Definitions

  • the present invention relates to peptides, nucleic acids and cells for use in immunotherapeutic methods.
  • the present invention relates to the immunotherapy of cancer.
  • the present invention furthermore relates to tumor-associated cytotoxic T cell (CTL) peptide epitopes, alone or in combination with other tumor-associated peptides that serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses.
  • CTL cytotoxic T cell
  • the present invention relates to several novel peptide sequences and their variants derived from HLA class I and HLA class II molecules of human tumor cells that can be used in vaccine compositions for eliciting anti-tumor immune responses.
  • B-cell chronic lymphocytic leukemia also known as chronic lymphoid leukemia (CLL) is the most common type of leukemia.
  • CLL cancers of the white blood cells (leukocytes).
  • CLL affects B cell lymphocytes.
  • B cells originate in the bone marrow, develop in the lymph nodes, and normally fight infection by producing antibodies.
  • B cells grow out of control and accumulate in the bone marrow and blood, where they crowd out healthy blood cells.
  • CLL is a stage of small lymphocytic lymphoma (SLL), a type of B-cell lymphoma, which presents primarily in the lymph nodes.
  • SLL and SLL are considered the same underlying disease, just with different appearances.
  • CLL is a disease of adults, but, in rare cases, it can occur in teenagers and occasionally in children (inherited). Most (>75%) people newly diagnosed with CLL are over the age of 50, and the majority are men, with a median age of 70 years at the time of diagnosis. Though less common, CLL sometimes affects people between 30 and 39 years of age. The incidence of CLL increases very quickly with increasing age.
  • CLL is very rare in Asian countries, such as Japan and China, and may account for as few as 10 percent of all leukemias in those regions.
  • CLL chronic lymphoid leukemia
  • the present invention employs peptides that stimulate the immune system of the patient and act as anti-tumor-agents in a non-invasive fashion.
  • the present invention relates to a peptide comprising an amino acid sequence selected from the group of SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016 or a variant sequence thereof which is at least 80%, preferably at least 90%, homologous (preferably at least 80% or at least 90% identical) to SEQ ID NO: 1 to SEQ ID NO: 225 or SEQ ID NO: 543 to SEQ ID NO: 1016, wherein said variant induces T cells cross-reacting with said peptide, or a pharmaceutical acceptable salt thereof, wherein said peptide is not the underlying full-length polypeptide.
  • the present invention further relates to a peptide of the present invention comprising a sequence that is selected from the group SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016 or a variant thereof, which is at least 80%, preferably at least 90%, homologous (preferably at least 80% or at least 90% identical) to SEQ ID NO: 1 to SEQ ID NO: 225 or SEQ ID NO: 543 to SEQ ID NO: 1016, wherein said peptide or variant thereof has an overall length for SEQ ID NO: 1 to SEQ ID NO: 225 of between 8 and 100, preferably between 8 and 30, and most preferred of between 8 and 14 amino acids, and for SEQ ID NO: SEQ ID NO: 543 to SEQ ID NO: 1016 of between 12 and 100, preferably between 12 and 30, and most preferred of between 12 to 18 amino acids.

  • CD8-positive T-cells which recognise Class I molecules of the major histocompatibility complex (MHC)-bearing peptides of usually 8 to 10 amino acid residues derived from proteins or defect ribosomal products (DRIPS) located in the cytosol, play an important role in this response.
  • MHC-molecules of the human are also designated as human leukocyte-antigens (HLA).
  • MHC class I molecules There are two classes of MHC-molecules: MHC class I molecules that can be found on most cells having a nucleus. MHC molecules are composed of an alpha heavy chain and beta-2-microglobulin (MHC class I receptors) or an alpha and a beta chain (MHC class II receptors), respectively. Their three-dimensional conformation results in a binding groove, which is used for non-covalent interaction with peptides. MHC class I present peptides that result from proteolytic cleavage of predominantly endogenous proteins, DRIPs and larger peptides.
  • MHC class I receptors alpha heavy chain and beta-2-microglobulin receptors
  • MHC class II receptors alpha and a beta chain
  • MHC class II molecules can be found predominantly on professional antigen presenting cells (APCs), and primarily present peptides of exogenous or transmembrane proteins that are taken up by APCs during the course of endocytosis, and are subsequently processed.
  • APCs professional antigen presenting cells
  • Complexes of peptide and MHC class I molecules are recognized by CD8-positive cytotoxic T-lymphocytes bearing the appropriate TCR (T-cell receptor), whereas complexes of peptide and MHC class II molecules are recognized by CD4-positive-helper-T cells bearing the appropriate TCR. It is well known that the TCR, the peptide and the MHC are thereby present in a stoichiometric amount of 1:1:1.
  • CD4-positive helper T cells play an important role in inducing and sustaining effective responses by CD8-positive cytotoxic T cells.
  • TAA tumor associated antigens
  • the identification of CD4-positive T-cell epitopes derived from tumor associated antigens (TAA) is of great importance for the development of pharmaceutical products for triggering anti-tumor immune responses (Gnjatic S, et al. Survey of naturally occurring CD4+ T cell responses against NY-ESO-1 in cancer patients: correlation with antibody responses. Proc Natl Acad Sci USA. 2003 Jul. 22; 100(15):8862-7).

  • IFN ⁇ interferon-gamma
  • CD4-positive T cells recognizing peptides from tumor-associated antigens presented by HLA class II molecules can counteract tumor progression via the induction of antibody (Ab) responses.
  • TAA tumor associated antigens
  • HLA class II molecules Since the constitutive expression of HLA class II molecules is usually limited to cells of the immune system, the possibility of isolating class II peptides directly from primary tumors was not considered possible. However, Dengjel et al. were successful in identifying a number of MHC Class II epitopes directly from tumors (WO 2007/028574, EP 1 760 088 B1; (Dengjel et al., 2006).
  • the antigens that are recognized by the tumor specific cytotoxic T lymphocytes can be molecules derived from all protein classes, such as enzymes, receptors, transcription factors, etc. which are expressed and, as compared to unaltered cells of the same origin, up-regulated in cells of the respective tumor.
  • CD8 and CD4 dependent Since both types of response, CD8 and CD4 dependent, contribute jointly and synergistically to the anti-tumor effect, the identification and characterization of tumor-associated antigens recognized by either CD8+ CTLs (ligand: MHC class I molecule+peptide epitope) or by CD4-positive T-helper cells (ligand: MHC class II molecule+peptide epitope) is important in the development of tumor vaccines.
  • the present invention also relates to two new and very useful MHC class II peptides (according to SEQ ID NO: 543 to SEQ ID NO: 1016). These peptides are particularly useful in the diagnosis and/or treatment of CLL and other cancers over-expressing and/or over—presenting the antigens the peptides are derived from respectively, such as AML.
  • the present invention also relates to so-called length variants of the inventive MHC class II peptides according to SEQ ID NO: 543 to SEQ ID NO: 1016.
  • the length variants are generally N- and/or C-terminally extended (between 1 and 5, preferably 1 to 10 amino acids) or N- and/or C-terminally shortened (between 1 and 5 amino acids) peptides, which still can bind to MHC, and elicit a cellular immune response as described herein.
  • peptides binding to class II proteins are not constrained in size and can vary from 11 to 30 amino acids in length.
  • the peptide binding groove in the MHC class II molecules is open at both ends, which enables binding of peptides with relatively longer length.
  • flanking regions are also important for the specificity of the peptide to the class II allele (see, for example, Meydan C, et al., Prediction of peptides binding to MHC class I and II alleles by temporal motif mining. BMC Bioinformatics. 2013; 14 Suppl 2: S13).
  • the person of skill in the art will be able to identify the binding motif, and thus identify the possibilities for extensions and/or deletions of the MHC class II peptides according to Table 1c, in order to create length variants.
  • MHC-class-1-binding peptides are usually 8-12 amino acid residues in length and usually contain two conserved residues (“anchors”) in their sequence that interact with the corresponding binding groove of the MHC-molecule. In this way each MHC allele has a “binding motif” determining which peptides can bind specifically to the binding groove.
  • peptides In the MHC class I dependent immune reaction, peptides not only have to be able to bind to certain MHC class I molecules being expressed by tumor cells, they also have to be recognized by T cells bearing specific T cell receptors (TCR).
  • TCR T cell receptors
  • the antigens that are recognized by the tumor specific cytotoxic T lymphocytes can be molecules derived from all protein classes, such as enzymes, receptors, transcription factors, etc. which are expressed and, as compared to unaltered cells of the same origin, up-regulated in cells of the respective tumor.
  • the current classification of tumor associated antigens comprises the following major groups:
  • Cancer-testis antigens The first TAAs ever identified that can be recognized by T cells belong to this class, which was originally called cancer-testis (CT) antigens because of the expression of its members in histologically different human tumors and, among normal tissues, only in spermatocytes/spermatogonia of testis and, occasionally, in placenta. Since the cells of testis do not express class I and II HLA molecules, these antigens cannot be recognized by T cells in normal tissues and can therefore be considered as immunologically tumor-specific.
  • CT antigens are the MAGE family members or NY-ESO-1.
  • TAAs Differentiation antigens: These TAAs are shared between tumors and the normal tissue from which the tumor arose; most are found in melanomas and normal melanocytes. Many of these melanocyte lineage-related proteins are involved in the biosynthesis of melanin and are therefore not tumor specific but nevertheless are widely used for cancer immunotherapy. Examples include, but are not limited to, tyrosinase and Melan-A/MART-1 for melanoma or PSA for prostate cancer.
  • TAAs Overexpressed TAAs: Genes encoding widely expressed TAAs have been detected in histologically different types of tumors as well as in many normal tissues, generally with lower expression levels. It is possible that many of the epitopes processed and potentially presented by normal tissues are below the threshold level for T-cell recognition, while their overexpression in tumor cells can trigger an anticancer response by breaking previously established tolerance. Prominent examples for this class of TAAs are Her-2/neu, Survivin, Telomerase or WT1.
  • Tumor specific antigens arise from mutations of normal genes (such as ⁇ -catenin, CDK4, etc.). Some of these molecular changes are associated with neoplastic transformation and/or progression. Tumor specific antigens are generally able to induce strong immune responses without bearing the risk for autoimmune reactions against normal tissues. On the other hand, these TAAs are in most cases only relevant to the exact tumor on which they were identified and are usually not shared between many individual tumors.
  • TAAs arising from abnormal post-translational modifications may arise from proteins which are neither specific nor overexpressed in tumors but nevertheless become tumor associated by posttranslational processes primarily active in tumors. Examples for this class arise from altered glycosylation patterns leading to novel epitopes in tumors as for MUC1 or events like protein splicing during degradation which may or may not be tumor specific.
  • Oncoviral proteins are viral proteins that may play a critical role in the oncogenic process and, because they are foreign (not of human origin), they can evoke a T-cell response. Examples of such proteins are the human papilloma type 16 virus proteins, E6 and E7, which are expressed in cervical carcinoma.
  • the antigen should be expressed mainly by tumor cells and not or in comparably small amounts by normal healthy tissues or in another preferred embodiment the peptide should be over-presented by tumor cells as compared to normal healthy tissues. It is furthermore desirable, that the respective antigen is not only present in a type of tumor, but also in high concentrations (i.e. copy numbers of the respective peptide per cell).
  • Tumor-specific and tumor-associated antigens are often derived from proteins directly involved in transformation of a normal cell to a tumor cell due to a function e.g. in cell cycle control or suppression of apoptosis.
  • downstream targets of the proteins directly causative for a transformation may be upregulated and thus may be indirectly tumor-associated.
  • Such indirect tumor-associated antigens may also be targets of a vaccination approach (Singh-Jasuja et al., 2004). In both cases it is essential that epitopes are present in the amino acid sequence of the antigen, since such a peptide (“immunogenic peptide”) that is derived from a tumor associated antigen should lead to an in vitro or in vivo T-cell-response.
  • any peptide able to bind a MHC molecule may function as a T-cell epitope.
  • a prerequisite for the induction of an in vitro or in vivo T-cell-response is the presence of a T cell with a corresponding TCR and the absence of immunological tolerance for this particular epitope.
  • TAAs are a starting point for the development of a tumor vaccine.
  • the methods for identifying and characterizing the TAAs are based on the use of CTL that can be isolated from patients or healthy subjects, or they are based on the generation of differential transcription profiles or differential peptide expression patterns between tumors and normal tissues.
  • the identification of genes over-expressed in tumor tissues or human tumor cell lines, or selectively expressed in such tissues or cell lines, does not provide precise information as to the use of the antigens being transcribed from these genes in an immune therapy. This is because only an individual subpopulation of epitopes of these antigens are suitable for such an application since a T cell with a corresponding TCR has to be present and immunological tolerance for this particular epitope needs to be absent or minimal. In a very preferred embodiment of the invention it is therefore important to select only those over- or selectively presented peptides against which a functional and/or a proliferating T cell can be found.
  • a functional T cell is defined as a T cell, which upon stimulation with a specific antigen can be clonally expanded and is able to execute effector functions (“effector T cell”).
  • the immunogenicity of the underlying peptides is secondary.
  • the presentation is the determining factor.
  • T-helper cells play an important role in orchestrating the effector function of CTLs in anti-tumor immunity.
  • T-helper cell epitopes that trigger a T-helper cell response of the T H1 type support effector functions of CD8-positive killer T cells, which include cytotoxic functions directed against tumor cells displaying tumor-associated peptide/MHC complexes on their cell surfaces.
  • tumor-associated T-helper cell peptide epitopes alone or in combination with other tumor-associated peptides, can serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses.

  • all quantitative data acquired for peptide candidates was inspected manually to assure data consistency and to verify the accuracy of the automated analysis. For each peptide a presentation profile was calculated showing the mean sample presentation as well as replicate variations. The profiles juxtapose CLL samples to a baseline of normal tissue samples. The presentation profile of an exemplary over-presented peptide is shown in FIG. 11 .

Abstract

    • Description of Related Art
  • B-cell chronic lymphocytic leukemia (B-CLL), also known as chronic lymphoid leukemia (CLL), is the most common type of leukemia.
  • Leukemias are cancers of the white blood cells (leukocytes). CLL affects B cell lymphocytes. B cells originate in the bone marrow, develop in the lymph nodes, and normally fight infection by producing antibodies. In CLL, B cells grow out of control and accumulate in the bone marrow and blood, where they crowd out healthy blood cells. CLL is a stage of small lymphocytic lymphoma (SLL), a type of B-cell lymphoma, which presents primarily in the lymph nodes. CLL and SLL are considered the same underlying disease, just with different appearances.
  • CLL is a disease of adults, but, in rare cases, it can occur in teenagers and occasionally in children (inherited). Most (>75%) people newly diagnosed with CLL are over the age of 50, and the majority are men, with a median age of 70 years at the time of diagnosis. Though less common, CLL sometimes affects people between 30 and 39 years of age. The incidence of CLL increases very quickly with increasing age.
  • In the United States, during 2012 about 16,060 new cases are expected to be diagnosed, and 4,580 patients are expected to die from CLL.
  • CLL is very rare in Asian countries, such as Japan and China, and may account for as few as 10 percent of all leukemias in those regions.
  • In view of the above, there remains a need for new efficacious and safe treatment option for cancers, in particular chronic lymphoid leukemia (CLL) and other cancers of the blood of different phenotypes which improve the well-being of the patients by not using excessive chemotherapeutic agents or other agents that may lead to severe side effects.
    • SUMMARY
  • The present invention employs peptides that stimulate the immune system of the patient and act as anti-tumor-agents in a non-invasive fashion.
  • In a first aspect of the present invention, the present invention relates to a peptide comprising an amino acid sequence selected from the group of SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016 or a variant sequence thereof which is at least 80%, preferably at least 90%, homologous (preferably at least 80% or at least 90% identical) to SEQ ID NO: 1 to SEQ ID NO: 225 or SEQ ID NO: 543 to SEQ ID NO: 1016, wherein said variant induces T cells cross-reacting with said peptide, or a pharmaceutical acceptable salt thereof, wherein said peptide is not the underlying full-length polypeptide.
  • The present invention further relates to a peptide of the present invention comprising a sequence that is selected from the group SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016 or a variant thereof, which is at least 80%, preferably at least 90%, homologous (preferably at least 80% or at least 90% identical) to SEQ ID NO: 1 to SEQ ID NO: 225 or SEQ ID NO: 543 to SEQ ID NO: 1016, wherein said peptide or variant thereof has an overall length for SEQ ID NO: 1 to SEQ ID NO: 225 of between 8 and 100, preferably between 8 and 30, and most preferred of between 8 and 14 amino acids, and for SEQ ID NO: SEQ ID NO: 543 to SEQ ID NO: 1016 of between 12 and 100, preferably between 12 and 30, and most preferred of between 12 to 18 amino acids.

  • B4GALT1 encodes a type II membrane-bound glycoprotein that appears to have exclusive specificity for the donor substrate UDP-galactose (RefSeq). B4GALT1 was shown to be up-regulated in a variety of highly metastatic cell lines such as human lung cancer and ovarian cancer cell lines and was described as a valuable candidate biomarker of invasive phenotype of colorectal cancer (Poeta et al., 2012; Zhou et al., 2012).
  • CP encodes a metalloprotein that binds most of the copper in plasma and is involved in the peroxidation of Fe(II)transferrin to Fe(III) transferrin (RefSeq).
  • CST3 encodes a member of the cystatin superfamily, which encompasses proteins that contain multiple cystatin-like sequences (RefSeq).
  • CTSH encodes a lysosomal cysteine proteinase, which is important in the overall degradation of lysosomal proteins (RefSeq). CTSH expression is increased in pathologic conditions including breast carcinoma, melanoma, gliomas, colorectal carcinoma and prostate carcinoma. CTSH-mediated processing of talin is thought to promote cancer cell progression by affecting integrin activation and adhesion strength (Jevnikar et al., 2013).
  • DNAJC5 encodes a member of the J protein family. J proteins function in many cellular processes by regulating the ATPase activity of 70 kDa heat shock proteins (RefSeq).
  • FAIM3 also known as TOSO encodes an Fc receptor for IgM (RefSeq). FAIM3 was identified as being over-expressed and associated with anti-apoptotic characteristics in chronic lymphocytic leukemia and it is regulated by B-cell receptor activation. These studies show that FAIM3 could be used as a prognostic marker for high-risk chronic lymphocytic leukemia (Pallasch et al., 2008; Yi et al., 2011; Yu et al., 2011).
  • FCER2 encodes a B-cell specific antigen and a low-affinity receptor for IgE. It has essential roles in B cell growth and differentiation, and the regulation of IgE production (RefSeq).
  • FMOD encodes a member of the family of small interstitial proteoglycans. The encoded protein possesses a central region containing leucine-rich repeats with 4 keratan sulfate chains, flanked by terminal domains containing disulphide bonds (RefSeq). FMOD was shown to be highly over-expressed in chronic lymphocytic leukemia cells. Hence, FMOD might serve as potential tumor-associated antigen in chronic lymphocytic leukemia (Mayr et al., 2005).
  • GALNT1 encodes a member of the UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase (GalNAc-T) family of enzymes (RefSeq). Studies have revealed that GALNT1 expression correlates with the degree of proliferation and recurrence in human breast cancer, ovarian cancer and bladder carcinoma. The latter suggests the use of GALNT1 as a clinical prognostic marker in human bladder carcinoma (Ding et al., 2012).
  • GLT8D1 encodes a member of the glycosyltransferase family (RefSeq). Studies revealed that GLT8D1 was ubiquitously up-regulated in the majority of human cancers, such as brain, liver, breast, lung, stomach, pancreas, colon, kidney, bladder, prostate and testis. GLT8D1-induced differentially methylated genes have strong potential as epigenetic biomarkers for early cancer screening, diagnostic, prognostic and therapeutic interventions (Teh et al., 2012).
  • GPI encodes a member of the glucose phosphate isomerase protein family (RefSeq). The GPI gene has been identified to be hypoxia inducible in human pancreatic cancer. The use of GPI inhibitors such as erythrose-4-phosphate diminishes the migratory and invasive capacities in bi-dimensional cultures of several breast cancer cell lines, suggesting that GPI inhibition could be a selective strategy to block tumor metastasis (Yoon et al., 2001; Gallardo-Perez et al., 2014).
  • GPX1 encodes a member of the glutathione peroxidase family (RefSeq). The GPX1 rs1050450 C>T polymorphism was associated with an increased risk of bladder cancer, but not prostate cancer. High expression of GPX1 in breast cancer cells of patients correlated with a worse clinical outcome and reduced overall survival of patients who underwent chemotherapy, implying that GPX1 could be used as a prognostic marker for these patients (Jardim et al., 2013; Men et al., 2014).
  • TFRC encodes the transferrin receptor and it is located on chromosome 3q29 (RefSeq). The expression rate of TFRC in oral squamous cell carcinoma was significantly higher than that in dysplasia, suggesting that oral squamous cell carcinoma disease progression might be related to TFRC expression. Anti-TFRC antibody blocked the interaction between transferrin and TFRC and, consequently, iron uptake. The resulting iron deprivation inhibited cell growth and induced apoptosis (Nagai et al., 2014).
  • UGCG encodes an enzyme that catalyzes the first glycosylation step in the biosynthesis of glycosphingolipids, which are membrane components containing lipid and sugar moieties (RefSeq). Studies have shown that UGCG is over-expressed in leukemia, breast cancer, renal cell cancer and papillary thyroid carcinomas. UGCG up-regulates MDR1 expression through activation of cSrc and beta-catenin signaling (Zhang et al., 2013; Liu et al., 2010).

  • Further, the present invention relates to a method for producing a personalized anti-cancer vaccine for an individual patient using a database (“warehouse”) of prescreened tumour associated peptides.
  • Stimulation of an immune response is dependent upon the presence of antigens recognised as foreign by the host immune system. The discovery of the existence of tumor associated antigens has raised the possibility of using a host's immune system to intervene in tumor growth. Various mechanisms of harnessing both the humoral and cellular arms of the immune system are currently being explored for cancer immunotherapy.
  • Specific elements of the cellular immune response are capable of specifically recognising and destroying tumor cells. The isolation of cytotoxic T-cells (CTL) from tumor-infiltrating cell populations or from peripheral blood suggests that such cells play an important role in natural immune defences against cancer. CD8-positive T-cells in particular, which recognise Class I molecules of the major histocompatibility complex (MHC)-bearing peptides of usually 8 to 10 amino acid residues derived from proteins or defect ribosomal products (DRIPS) located in the cytosol, play an important role in this response. The MHC-molecules of the human are also designated as human leukocyte-antigens (HLA).
  • There are two classes of MHC-molecules: MHC class I molecules that can be found on most cells having a nucleus. MHC molecules are composed of an alpha heavy chain and beta-2-microglobulin (MHC class I receptors) or an alpha and a beta chain (MHC class II receptors), respectively. Their three-dimensional conformation results in a binding groove, which is used for non-covalent interaction with peptides. MHC class I present peptides that result from proteolytic cleavage of predominantly endogenous proteins, DRIPs and larger peptides. MHC class II molecules can be found predominantly on professional antigen presenting cells (APCs), and primarily present peptides of exogenous or transmembrane proteins that are taken up by APCs during the course of endocytosis, and are subsequently processed. Complexes of peptide and MHC class I molecules are recognized by CD8-positive cytotoxic T-lymphocytes bearing the appropriate TCR (T-cell receptor), whereas complexes of peptide and MHC class II molecules are recognized by CD4-positive-helper-T cells bearing the appropriate TCR. It is well known that the TCR, the peptide and the MHC are thereby present in a stoichiometric amount of 1:1:1.
  • CD4-positive helper T cells play an important role in inducing and sustaining effective responses by CD8-positive cytotoxic T cells. The identification of CD4-positive T-cell epitopes derived from tumor associated antigens (TAA) is of great importance for the development of pharmaceutical products for triggering anti-tumor immune responses (Gnjatic S, et al. Survey of naturally occurring CD4+ T cell responses against NY-ESO-1 in cancer patients: correlation with antibody responses. Proc Natl Acad Sci USA. 2003 Jul. 22; 100(15):8862-7). At the tumor site, T helper cells, support a CTL friendly cytokine milieu Mortara L, et al. CIITA-induced MHC class II expression in mammary adenocarcinoma leads to a Th1 polarization of the tumor microenvironment, tumor rejection, and specific antitumor memory. Clin Cancer Res. 2006 Jun. 1; 12(11 Pt 1):3435-43) and attract effector cells, e.g. CTLs, NK cells, macrophages, granulocytes (Hwang M L, et al. Cognate memory CD4+ T cells generated with dendritic cell priming influence the expansion, trafficking, and differentiation of secondary CD8+ T cells and enhance tumor control. J Immunol. 2007 Nov. 1; 179(9):5829-38).
  • In the absence of inflammation, expression of MHC class II molecules is mainly restricted to cells of the immune system, especially professional antigen-presenting cells (APC), e.g., monocytes, monocyte-derived cells, macrophages, dendritic cells. In cancer patients, cells of the tumor have surprisingly been found to express MHC class II molecules (Dengjel J, et al. Unexpected abundance of HLA class II presented peptides in primary renal cell carcinomas. Clin Cancer Res. 2006 Jul. 15; 12(14 Pt 1):4163-70).
  • It was shown in mammalian animal models, e.g., mice, that even in the absence of CTL effector cells (i.e., CD8-positive T lymphocytes), CD4-positive T cells are sufficient for inhibiting manifestation of tumors via inhibition of angiogenesis by secretion of interferon-gamma (IFNγ).
  • Additionally, it was shown that CD4-positive T cells recognizing peptides from tumor-associated antigens presented by HLA class II molecules can counteract tumor progression via the induction of antibody (Ab) responses.
  • In contrast to tumor-associated peptides binding to HLA class I molecules, only a small number of class II ligands of tumor associated antigens (TAA) have been described to date.
  • Since the constitutive expression of HLA class II molecules is usually limited to cells of the immune system, the possibility of isolating class II peptides directly from primary tumors was not considered possible. However, Dengjel et al. were successful in identifying a number of MHC Class II epitopes directly from tumors (WO 2007/028574, EP 1 760 088 B1; (Dengjel et al., 2006).
  • The antigens that are recognized by the tumor specific cytotoxic T lymphocytes, that is, their epitopes, can be molecules derived from all protein classes, such as enzymes, receptors, transcription factors, etc. which are expressed and, as compared to unaltered cells of the same origin, up-regulated in cells of the respective tumor.
  • Since both types of response, CD8 and CD4 dependent, contribute jointly and synergistically to the anti-tumor effect, the identification and characterization of tumor-associated antigens recognized by either CD8+ CTLs (ligand: MHC class I molecule+peptide epitope) or by CD4-positive T-helper cells (ligand: MHC class II molecule+peptide epitope) is important in the development of tumor vaccines.
  • The present invention also relates to two new and very useful MHC class II peptides (according to SEQ ID NO: 543 to SEQ ID NO: 1016). These peptides are particularly useful in the diagnosis and/or treatment of CLL and other cancers over-expressing and/or over—presenting the antigens the peptides are derived from respectively, such as AML.
  • The present invention also relates to so-called length variants of the inventive MHC class II peptides according to SEQ ID NO: 543 to SEQ ID NO: 1016.
  • The length variants are generally N- and/or C-terminally extended (between 1 and 5, preferably 1 to 10 amino acids) or N- and/or C-terminally shortened (between 1 and 5 amino acids) peptides, which still can bind to MHC, and elicit a cellular immune response as described herein. As is known in the state of the art, peptides binding to class II proteins are not constrained in size and can vary from 11 to 30 amino acids in length. The peptide binding groove in the MHC class II molecules is open at both ends, which enables binding of peptides with relatively longer length. Though the “core” nine residues long segment contributes the most to the recognition of the peptide, the flanking regions are also important for the specificity of the peptide to the class II allele (see, for example, Meydan C, et al., Prediction of peptides binding to MHC class I and II alleles by temporal motif mining. BMC Bioinformatics. 2013; 14 Suppl 2: S13). Using the many software tools as available (e.g. as described above), the person of skill in the art will be able to identify the binding motif, and thus identify the possibilities for extensions and/or deletions of the MHC class II peptides according to Table 1c, in order to create length variants.
  • For a peptide to trigger (elicit) a cellular immune response, it must bind to an MHC-molecule. This process is dependent on the allele of the MHC-molecule and specific polymorphisms of the amino acid sequence of the peptide. MHC-class-1-binding peptides are usually 8-12 amino acid residues in length and usually contain two conserved residues (“anchors”) in their sequence that interact with the corresponding binding groove of the MHC-molecule. In this way each MHC allele has a “binding motif” determining which peptides can bind specifically to the binding groove.
  • In the MHC class I dependent immune reaction, peptides not only have to be able to bind to certain MHC class I molecules being expressed by tumor cells, they also have to be recognized by T cells bearing specific T cell receptors (TCR).
  • The antigens that are recognized by the tumor specific cytotoxic T lymphocytes, that is, their epitopes, can be molecules derived from all protein classes, such as enzymes, receptors, transcription factors, etc. which are expressed and, as compared to unaltered cells of the same origin, up-regulated in cells of the respective tumor.
  • The current classification of tumor associated antigens comprises the following major groups:
  • a) Cancer-testis antigens: The first TAAs ever identified that can be recognized by T cells belong to this class, which was originally called cancer-testis (CT) antigens because of the expression of its members in histologically different human tumors and, among normal tissues, only in spermatocytes/spermatogonia of testis and, occasionally, in placenta. Since the cells of testis do not express class I and II HLA molecules, these antigens cannot be recognized by T cells in normal tissues and can therefore be considered as immunologically tumor-specific. Well-known examples for CT antigens are the MAGE family members or NY-ESO-1.
  • b) Differentiation antigens: These TAAs are shared between tumors and the normal tissue from which the tumor arose; most are found in melanomas and normal melanocytes. Many of these melanocyte lineage-related proteins are involved in the biosynthesis of melanin and are therefore not tumor specific but nevertheless are widely used for cancer immunotherapy. Examples include, but are not limited to, tyrosinase and Melan-A/MART-1 for melanoma or PSA for prostate cancer.
  • c) Overexpressed TAAs: Genes encoding widely expressed TAAs have been detected in histologically different types of tumors as well as in many normal tissues, generally with lower expression levels. It is possible that many of the epitopes processed and potentially presented by normal tissues are below the threshold level for T-cell recognition, while their overexpression in tumor cells can trigger an anticancer response by breaking previously established tolerance. Prominent examples for this class of TAAs are Her-2/neu, Survivin, Telomerase or WT1.
  • d) Tumor specific antigens: These unique TAAs arise from mutations of normal genes (such as β-catenin, CDK4, etc.). Some of these molecular changes are associated with neoplastic transformation and/or progression. Tumor specific antigens are generally able to induce strong immune responses without bearing the risk for autoimmune reactions against normal tissues. On the other hand, these TAAs are in most cases only relevant to the exact tumor on which they were identified and are usually not shared between many individual tumors.
  • e) TAAs arising from abnormal post-translational modifications: Such TAAs may arise from proteins which are neither specific nor overexpressed in tumors but nevertheless become tumor associated by posttranslational processes primarily active in tumors. Examples for this class arise from altered glycosylation patterns leading to novel epitopes in tumors as for MUC1 or events like protein splicing during degradation which may or may not be tumor specific.
  • f) Oncoviral proteins: These TAAs are viral proteins that may play a critical role in the oncogenic process and, because they are foreign (not of human origin), they can evoke a T-cell response. Examples of such proteins are the human papilloma type 16 virus proteins, E6 and E7, which are expressed in cervical carcinoma.
  • For proteins to be recognized by cytotoxic T-lymphocytes as tumor-specific or -associated antigens, and to be used in a therapy, particular prerequisites must be fulfilled. The antigen should be expressed mainly by tumor cells and not or in comparably small amounts by normal healthy tissues or in another preferred embodiment the peptide should be over-presented by tumor cells as compared to normal healthy tissues. It is furthermore desirable, that the respective antigen is not only present in a type of tumor, but also in high concentrations (i.e. copy numbers of the respective peptide per cell). Tumor-specific and tumor-associated antigens are often derived from proteins directly involved in transformation of a normal cell to a tumor cell due to a function e.g. in cell cycle control or suppression of apoptosis. Additionally, downstream targets of the proteins directly causative for a transformation may be upregulated and thus may be indirectly tumor-associated. Such indirect tumor-associated antigens may also be targets of a vaccination approach (Singh-Jasuja et al., 2004). In both cases it is essential that epitopes are present in the amino acid sequence of the antigen, since such a peptide (“immunogenic peptide”) that is derived from a tumor associated antigen should lead to an in vitro or in vivo T-cell-response.
  • Basically, any peptide able to bind a MHC molecule may function as a T-cell epitope. A prerequisite for the induction of an in vitro or in vivo T-cell-response is the presence of a T cell with a corresponding TCR and the absence of immunological tolerance for this particular epitope.
  • Therefore, TAAs are a starting point for the development of a tumor vaccine. The methods for identifying and characterizing the TAAs are based on the use of CTL that can be isolated from patients or healthy subjects, or they are based on the generation of differential transcription profiles or differential peptide expression patterns between tumors and normal tissues.
  • However, the identification of genes over-expressed in tumor tissues or human tumor cell lines, or selectively expressed in such tissues or cell lines, does not provide precise information as to the use of the antigens being transcribed from these genes in an immune therapy. This is because only an individual subpopulation of epitopes of these antigens are suitable for such an application since a T cell with a corresponding TCR has to be present and immunological tolerance for this particular epitope needs to be absent or minimal. In a very preferred embodiment of the invention it is therefore important to select only those over- or selectively presented peptides against which a functional and/or a proliferating T cell can be found. Such a functional T cell is defined as a T cell, which upon stimulation with a specific antigen can be clonally expanded and is able to execute effector functions (“effector T cell”).
  • In case of TCRs and antibodies according to the invention the immunogenicity of the underlying peptides is secondary. For TCRs and antibodies according to the invention the presentation is the determining factor.
  • T-helper cells play an important role in orchestrating the effector function of CTLs in anti-tumor immunity. T-helper cell epitopes that trigger a T-helper cell response of the TH1 type support effector functions of CD8-positive killer T cells, which include cytotoxic functions directed against tumor cells displaying tumor-associated peptide/MHC complexes on their cell surfaces. In this way tumor-associated T-helper cell peptide epitopes, alone or in combination with other tumor-associated peptides, can serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses.
  • The inventors identified a novel category of ligandome-derived tumor-associated antigens (LiTAAs), which were frequently and exclusively detected in CLL patients. Specific immune recognition of the corresponding HLA ligands (LiTAPs) was observed exclusively in CLL patients, remarkably showing a direct correlation with the frequency of HLA restricted presentation. Furthermore, retrospective survival analysis of 33 CLL patients indicated a potential association of LiTAP-specific immune responses with improved overall survival in CLL patients.
  • Uses against further cancers are disclosed in the following description of the proteins of the peptides according to the invention.
  • As used herein and except as noted otherwise all terms are defined as given below.
  • The term “peptide” is used herein to designate a series of amino acid residues, connected one to the other typically by peptide bonds between the alpha-amino and carbonyl groups of the adjacent amino acids. The peptides are preferably 9 amino acids in length, but can be as short as 8 amino acids in length, and as long as 10, 11, 12, 13 or 14 and in case of MHC class II peptides they can be as long as 15, 16, 17, 18, 19 or 20 amino acids in length.
  • Furthermore, the term “peptide” shall include salts of a series of amino acid residues, connected one to the other typically by peptide bonds between the alpha-amino and carbonyl groups of the adjacent amino acids. Preferably, the salts are pharmaceutical acceptable salts of the peptides, such as, for example, the chloride or acetate (trifluoroacetate) salts.
  • The term “peptide” shall include “oligopeptide”. The term “oligopeptide” is used herein to designate a series of amino acid residues, connected one to the other typically by peptide bonds between the alpha-amino and carbonyl groups of the adjacent amino acids. The length of the oligopeptide is not critical to the invention, as long as the correct epitope or epitopes are maintained therein. The oligopeptides are typically less than about 30 amino acid residues in length, and greater than about 15 amino acids in length.
  • The term “the peptides of the present invention” shall include the peptides consisting of or comprising a peptide as defined above according to SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 527 to SEQ ID NO: 551 or SEQ ID NO: 552 to SEQ ID NO: 1016.
  • The term “polypeptide” designates a series of amino acid residues, connected one to the other typically by peptide bonds between the alpha-amino and carbonyl groups of the adjacent amino acids. The length of the polypeptide is not critical to the invention as long as the correct epitopes are maintained. In contrast to the terms peptide or oligopeptide, the term polypeptide is meant to refer to molecules containing more than about 30 amino acid residues.
  • A peptide, oligopeptide, protein or polynucleotide coding for such a molecule is “immunogenic” (and thus is an “immunogen” within the present invention), if it is capable of inducing an immune response. In the case of the present invention, immunogenicity is more specifically defined as the ability to induce a T-cell response. Thus, an “immunogen” would be a molecule that is capable of inducing an immune response, and in the case of the present invention, a molecule capable of inducing a T-cell response. In another aspect, the immunogen can be the peptide, the complex of the peptide with MHC, oligopeptide, and/or protein that is used to raise specific antibodies or TCRs against it.
  • A class I T cell “epitope” requires a short peptide that is bound to a class I MHC receptor, forming a ternary complex (MHC class I alpha chain, beta-2-microglobulin, and peptide) that can be recognized by a T cell bearing a matching T-cell receptor binding to the MHC/peptide complex with appropriate affinity. Peptides binding to MHC class I molecules are typically 8-14 amino acids in length, and most typically 9 amino acids in length.
  • In humans there are three different genetic loci that encode MHC class I molecules (the MHC-molecules of the human are also designated human leukocyte antigens (HLA)): HLA-A, HLA-B, and HLA-C. HLA-A*01, HLA-A*02, and HLA-B*07 are examples of different MHC class I alleles that can be expressed from these loci.

  • Therefore, for therapeutic and diagnostic purposes a peptide that binds with appropriate affinity to several different HLA class II receptors is highly desirable. A peptide binding to several different HLA class II molecules is called a promiscuous binder.
  • As used herein, reference to a DNA sequence includes both single stranded and double stranded DNA. Thus, the specific sequence, unless the context indicates otherwise, refers to the single strand DNA of such sequence, the duplex of such sequence with its complement (double stranded DNA) and the complement of such sequence. The term “coding region” refers to that portion of a gene which either naturally or normally codes for the expression product of that gene in its natural genomic environment, i.e., the region coding in vivo for the native expression product of the gene.
  • The coding region can be from a non-mutated (“normal”), mutated or altered gene, or can even be from a DNA sequence, or gene, wholly synthesized in the laboratory using methods well known to those of skill in the art of DNA synthesis.
  • The term “nucleotide sequence” refers to a heteropolymer of deoxyribonucleotides.
  • The nucleotide sequence coding for a particular peptide, oligopeptide, or polypeptide may be naturally occurring or they may be synthetically constructed. Generally, DNA segments encoding the peptides, polypeptides, and proteins of this invention are assembled from cDNA fragments and short oligonucleotide linkers, or from a series of oligonucleotides, to provide a synthetic gene that is capable of being expressed in a recombinant transcriptional unit comprising regulatory elements derived from a microbial or viral operon.
  • As used herein the term “a nucleotide coding (or encoding) for a peptide” refers to a nucleotide sequence coding for the peptide including artificial (man-made) start and stop codons compatible for the biological system the sequence is going to be expressed by.
  • The term “expression product” means the polypeptide or protein that is the natural translation product of the gene and any nucleic acid sequence coding equivalents resulting from genetic code degeneracy and thus coding for the same amino acid(s).
  • The term “fragment”, when referring to a coding sequence, means a portion of DNA comprising less than the complete coding region, whose expression product retains essentially the same biological function or activity as the expression product of the complete coding region.
  • The term “DNA segment” refers to a DNA polymer, in the form of a separate fragment or as a component of a larger DNA construct, which has been derived from DNA isolated at least once in substantially pure form, i.e., free of contaminating endogenous materials and in a quantity or concentration enabling identification, manipulation, and recovery of the segment and its component nucleotide sequences by standard biochemical methods, for example, by using a cloning vector. Such segments are provided in the form of an open reading frame uninterrupted by internal non-translated sequences, or introns, which are typically present in eukaryotic genes. Sequences of non-translated DNA may be present downstream from the open reading frame, where the same do not interfere with manipulation or expression of the coding regions.
  • The term “primer” means a short nucleic acid sequence that can be paired with one strand of DNA and provides a free 3′-OH end at which a DNA polymerase starts synthesis of a deoxyribonucleotide chain.
  • The term “promoter” means a region of DNA involved in binding of RNA polymerase to initiate transcription.
  • The term “isolated” means that the material is removed from its original environment (e.g., the natural environment if it is naturally occurring). For example, a naturally-occurring polynucleotide or polypeptide present in a living animal is not isolated, but the same polynucleotide or polypeptide, separated from some or all of the coexisting materials in the natural system, is isolated. Such polynucleotides could be part of a vector and/or such polynucleotides or polypeptides could be part of a composition, and still be isolated in that such vector or composition is not part of its natural environment.
  • The polynucleotides, and recombinant or immunogenic polypeptides, disclosed in accordance with the present invention may also be in “purified” form. The term “purified” does not require absolute purity; rather, it is intended as a relative definition, and can include preparations that are highly purified or preparations that are only partially purified, as those terms are understood by those of skill in the relevant art. For example, individual clones isolated from a cDNA library have been conventionally purified to electrophoretic homogeneity. Purification of starting material or natural material to at least one order of magnitude, preferably two or three orders, and more preferably four or five orders of magnitude is expressly contemplated. Furthermore, a claimed polypeptide which has a purity of preferably 99.999%, or at least 99.99% or 99.9%; and even desirably 99% by weight or greater is expressly contemplated.
  • The nucleic acids and polypeptide expression products disclosed according to the present invention, as well as expression vectors containing such nucleic acids and/or such polypeptides, may be in “enriched form”. As used herein, the term “enriched” means that the concentration of the material is at least about 2, 5, 10, 100, or 1000 times its natural concentration (for example), advantageously 0.01%, by weight, preferably at least about 0.1% by weight. Enriched preparations of about 0.5%, 1%, 5%, 10%, and 20% by weight are also contemplated. The sequences, constructs, vectors, clones, and other materials comprising the present invention can advantageously be in enriched or isolated form.
  • The term “active fragment” means a fragment that generates an immune response (i.e., has immunogenic activity) when administered, alone or optionally with a suitable adjuvant, to an animal, such as a mammal, for example, a rabbit or a mouse, and also including a human, such immune response taking the form of stimulating a T-cell response within the recipient animal, such as a human. Alternatively, the “active fragment” may also be used to induce a T-cell response in vitro.
  • As used herein, the terms “portion”, “segment” and “fragment,” when used in relation to polypeptides, refer to a continuous sequence of residues, such as amino acid residues, which sequence forms a subset of a larger sequence. For example, if a polypeptide were subjected to treatment with any of the common endopeptidases, such as trypsin or chymotrypsin, the oligopeptides resulting from such treatment would represent portions, segments or fragments of the starting polypeptide. When used in relation to polynucleotides, these terms refer to the products produced by treatment of said polynucleotides with any of the endonucleases.
  • In accordance with the present invention, the term “percent identity” or “percent identical”, when referring to a sequence, means that a sequence is compared to a claimed or described sequence after alignment of the sequence to be compared (the “Compared Sequence”) with the described or claimed sequence (the “Reference Sequence”). The Percent Identity is then determined according to the following formula:

  • Percent Identity=100 [1−(C/R)]
  • wherein C is the number of differences between the Reference Sequence and the Compared Sequence over the length of alignment between the Reference Sequence and the Compared Sequence, wherein
  • (i) each base or amino acid in the Reference Sequence that does not have a corresponding aligned base or amino acid in the Compared Sequence and
  • (ii) each gap in the Reference Sequence and
  • (iii) each aligned base or amino acid in the Reference Sequence that is different from an aligned base or amino acid in the Compared Sequence, constitutes a difference and
  • (iiii) the alignment has to start at position 1 of the aligned sequences;
  • and R is the number of bases or amino acids in the Reference Sequence over the length of the alignment with the Compared Sequence with any gap created in the Reference Sequence also being counted as a base or amino acid.
  • If an alignment exists between the Compared Sequence and the Reference Sequence for which the Percent Identity as calculated above is about equal to or greater than a specified minimum Percent Identity then the Compared Sequence has the specified minimum Percent Identity to the Reference Sequence even though alignments may exist in which the herein above calculated Percent Identity is less than the specified Percent Identity.
  • The original (unmodified) peptides as disclosed herein can be modified by the substitution of one or more residues at different, possibly selective, sites within the peptide chain, if not otherwise stated. Preferably those substitutions are located at the end of the amino acid chain. Such substitutions may be of a conservative nature, for example, where one amino acid is replaced by an amino acid of similar structure and characteristics, such as where a hydrophobic amino acid is replaced by another hydrophobic amino acid. Even more conservative would be replacement of amino acids of the same or similar size and chemical nature, such as where leucine is replaced by isoleucine. In studies of sequence variations in families of naturally occurring homologous proteins, certain amino acid substitutions are more often tolerated than others, and these are often show correlation with similarities in size, charge, polarity, and hydrophobicity between the original amino acid and its replacement, and such is the basis for defining “conservative substitutions.”
  • Conservative substitutions are herein defined as exchanges within one of the following five groups: Group 1-small aliphatic, nonpolar or slightly polar residues (Ala, Ser, Thr, Pro, Gly); Group 2-polar, negatively charged residues and their amides (Asp, Asn, Glu, Gln); Group 3-polar, positively charged residues (His, Arg, Lys); Group 4-large, aliphatic, nonpolar residues (Met, Leu, Ile, Val, Cys); and Group 5-large, aromatic residues (Phe, Tyr, Trp).
  • Less conservative substitutions might involve the replacement of one amino acid by another that has similar characteristics but is somewhat different in size, such as replacement of an alanine by an isoleucine residue. Highly non-conservative replacements might involve substituting an acidic amino acid for one that is polar, or even for one that is basic in character. Such “radical” substitutions cannot, however, be dismissed as potentially ineffective since chemical effects are not totally predictable and radical substitutions might well give rise to serendipitous effects not otherwise predictable from simple chemical principles.
  • Of course, such substitutions may involve structures other than the common L-amino acids. Thus, D-amino acids might be substituted for the L-amino acids commonly found in the antigenic peptides of the invention and yet still be encompassed by the disclosure herein. In addition, amino acids possessing non-standard R groups (i.e., R groups other than those found in the common 20 amino acids of natural proteins) may also be used for substitution purposes to produce immunogens and immunogenic polypeptides according to the present invention.
  • If substitutions at more than one position are found to result in a peptide with substantially equivalent or greater antigenic activity as defined below, then combinations of those substitutions will be tested to determine if the combined substitutions result in additive or synergistic effects on the antigenicity of the peptide. At most, no more than 4 positions within the peptide would simultaneously be substituted.
  • The peptides of the invention can be elongated by up to four amino acids, that is 1, 2, 3 or 4 amino acids can be added to either end in any combination between 4:0 and 0:4.
  • Combinations of the elongations according to the invention can be depicted from table 8:
  •
    C-terminus N-terminus
    4 0
    3 0 or 1
    2 0 or 1 or 2
    1 0 or 1 or 2 or 3
    0 0 or 1 or 2 or 3 or 4
    N-terminus C-terminus
    4 0
    3 0 or 1
    2 0 or 1 or 2
    1 0 or 1 or 2 or 3
    0 0 or 1 or 2 or 3 or 4
  • The amino acids for the elongation can be the peptides of the original sequence of the protein or any other amino acid. The elongation can be used to enhance the stability or solubility of the peptides.
  • The term “T-cell response” means the specific proliferation and activation of effector functions induced by a peptide in vitro or in vivo. For MHC class I restricted CTLs, effector functions may be lysis of peptide-pulsed, peptide-precursor pulsed or naturally peptide-presenting target cells, secretion of cytokines, preferably Interferon-gamma, TNF-alpha, or IL-2 induced by peptide, secretion of effector molecules, preferably granzymes or perforins induced by peptide, or degranulation.
  • Preferably, when the CTLs specific for a peptide according to the present invention are tested against the substituted peptides, the peptide concentration at which the substituted peptides achieve half the maximal increase in lysis relative to background is no more than about 1 mM, preferably no more than about 1 μM, more preferably no more than about 1 nM, and still more preferably no more than about 100 pM, and most preferably no more than about 10 pM. It is also preferred that the substituted peptide be recognized by CTLs from more than one individual, at least two, and more preferably three individuals.
  • Thus, the epitopes of the present invention may be identical to naturally occurring tumor-associated or tumor-specific epitopes or may include epitopes that differ by no more than 4 residues from the reference peptide, as long as they have substantially identical antigenic activity.
  • Stimulation of an immune response is dependent upon the presence of antigens recognized as foreign by the host immune system. The discovery of the existence of tumor associated antigens has now raised the possibility of using a host's immune system to intervene in tumor growth. Various mechanisms of harnessing both the humoral and cellular arms of the immune system are currently explored for cancer immunotherapy.
  • Specific elements of the cellular immune response are capable of specifically recognizing and destroying tumor cells. The isolation of cytotoxic T-cells (CTL) from tumor-infiltrating cell populations or from peripheral blood suggests that such cells play an important role in natural immune defences against cancer. CD8-positive T-cells in particular, which recognize class I molecules of the major histocompatibility complex (MHC)-bearing peptides of usually 8 to 12 residues derived from proteins or defect ribosomal products (DRIPS) located in the cytosols, play an important role in this response. The MHC-molecules of the human are also designated as human leukocyte-antigens (HLA).
  • MHC class I molecules can be found on most cells having a nucleus which present peptides that result from proteolytic cleavage of mainly endogenous, cytosolic or nuclear proteins, DRIPS, and larger peptides. However, peptides derived from endosomal compartments or exogenous sources are also frequently found on MHC class I molecules. This non-classical way of class I presentation is referred to as cross-presentation in literature.
  • Since both types of response, CD8 and CD4 dependent, contribute jointly and synergistically to the anti-tumor effect, the identification and characterization of tumor-associated antigens recognized by either CD8-positive CTLs (MHC class I molecule) or by CD4-positive CTLs (MHC class II molecule) is important in the development of tumor vaccines. It is therefore an object of the present invention, to provide compositions of peptides that contain peptides binding to MHC complexes of either class.
  • Considering the severe side-effects and expense associated with treating cancer better prognosis and diagnostic methods are desperately needed. Therefore, there is a need to identify other factors representing biomarkers for cancer in general and CLL in particular. Furthermore, there is a need to identify factors that can be used in the treatment of cancer in general and CLL in particular.
  • The present invention provides peptides that are useful in treating cancers/tumors, preferably CLL that over- or exclusively present the peptides of the invention. These peptides were shown by mass spectrometry to be naturally presented by HLA molecules on primary human CLL samples.
  • The source gene/protein (also designated “full-length protein” or “underlying protein”) from which the peptides are derived were shown to be highly overexpressed in diseased (e.g. cancerous) compared with normal tissues. “Normal tissues” in relation to this invention shall particularly mean a blood sample from a healthy donor and sub-populations of blood cells,especially white blood cells, (see example 2, and FIGS. 2a-2f ) demonstrating a high degree of tumor association of the source genes. Moreover, the peptides themselves are strongly over-presented on tumor tissue—“tumor tissue” in relation to this invention shall mean a blood sample from a patient suffering from CLL and sub-populations of blood cells,especially white blood cells, but not on normal tissues (see example 3 and FIGS. 3a-3e ).
  • HLA-bound peptides can be recognized by the immune system, specifically T lymphocytes/T cells. T cells can destroy the cells presenting the recognized HLA/peptide complex, e.g. cells presenting the peptides of the present invention that are derived from their underlying proteins.
  • The peptides of the present invention have been shown to be capable of stimulating T cell responses and/or are over-presented and thus can be used for the production of antibodies and/or TCRs, in particular sTCRs, according to the present invention (see example 4 and FIG. 4a-4g ). Furthermore, the peptides when complexed with the respective MHC can be used for the production of antibodies and/or TCRs, in particular sTCRs, according to the present invention, as well. Respective methods are well known to the person of skill, and can be found in the respective literature as well. Thus, the peptides of the present invention are useful for generating an immune response in a patient by which tumor cells can be destroyed. An immune response in a patient can be induced by direct administration of the described peptides or suitable precursor substances (e.g. elongated peptides, proteins, or nucleic acids encoding these peptides) to the patient, ideally in combination with an agent enhancing the immunogenicity (i.e. an adjuvant). The immune response originating from such a therapeutic vaccination can be expected to be highly specific against tumor cells because the target peptides of the present invention are not presented on normal tissues in comparable copy numbers, preventing the risk of undesired autoimmune reactions against normal cells in the patient.
  • A “pharmaceutical composition” is a composition suitable for administration to a human being in a medical setting. Preferably, said pharmaceutical composition is sterile and produced according to the GMP guidelines.
  • The pharmaceutical compositions comprise the peptides either in the free form or in the form of a pharmaceutically acceptable salt (see also above). As used herein, “a pharmaceutically acceptable salt” refers to a derivative of the disclosed peptides wherein the peptide is modified by making acid or base salts of the agent. For example, acid salts are prepared from the free base (typically wherein the neutral form of the drug has a neutral —NH2 group) involving reaction with a suitable acid. Suitable acids for preparing acid salts include both organic acids, e.g., acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methane sulfonic acid, ethane sulfonic acid, p-toluenesulfonic acid, salicylic acid, and the like, as well as inorganic acids, e.g., hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid phosphoric acid and the like. Conversely, preparation of basic salts of acid moieties which may be present on a peptide are prepared using a pharmaceutically acceptable base such as sodium hydroxide, potassium hydroxide, ammonium hydroxide, calcium hydroxide, trimethylamine or the like.
  • In an especially preferred embodiment, the pharmaceutical compositions comprise the peptides as salts of acetic acid (acetates), trifluoro acetates or hydrochloric acid (chlorides).
  • In addition to being useful for treating cancer, the peptides of the present invention are also useful as diagnostics. Since the peptides were generated from CLL (leukimea) cells and since it was determined that these peptides are not or at lower levels present in normal tissues (such as white blood cells), these peptides can be used to diagnose the presence of a cancer.
  • The presence of claimed peptides in blood samples can assist a pathologist in diagnosis of cancer. Detection of certain peptides by means of antibodies, mass spectrometry or other methods known in the art can tell the pathologist that the sample is malignant or generally diseased, or can be usesd as a biomarker for CLL. Presence of groups of peptides can enable classification or sub-classification of diseased tissues.
  • The detection of peptides on diseased tissue specimen can enable the decision about the benefit of therapies involving the immune system, especially if T-lymphocytes are known or expected to be involved in the mechanism of action. Loss of MHC expression is a well described mechanism by which infected of malignant cells escape immuno-surveillance. Thus, presence of peptides shows that this mechanism is not exploited by the analyzed cells.
  • The peptides of the present invention might be used to analyze lymphocyte responses against those peptides such as T cell responses or antibody responses against the peptide or the peptide complexed to MHC molecules. These lymphocyte responses can be used as prognostic markers for decision on further therapy steps. These responses can also be used as surrogate markers in immunotherapy approaches aiming to induce lymphocyte responses by different means, e.g. vaccination of protein, nucleic acids, autologous materials, adoptive transfer of lymphocytes. In gene therapy settings, lymphocyte responses against peptides can be considered in the assessment of side effects. Monitoring of lymphocyte responses might also be a valuable tool for follow-up examinations of transplantation therapies, e.g. for the detection of graft versus host and host versus graft diseases.
  • The peptides of the present invention can be used to generate and develop specific antibodies against MHC/peptide complexes. These can be used for therapy, targeting toxins or radioactive substances to the diseased tissue. Another use of these antibodies can be targeting radionuclides to the diseased tissue for imaging purposes such as PET. This use can help to detect small metastases or to determine the size and precise localization of diseased tissues.
  • Therefore, it is a further aspect of the invention to provide a method for producing a recombinant antibody specifically binding to a human major histocompatibility complex (MHC) class I or II being complexed with a HLA-restricted antigen, the method comprising: immunizing a genetically engineered non-human mammal comprising cells expressing said human major histocompatibility complex (MHC) class I or II with a soluble form of a MHC class I or II molecule being complexed with said HLA-restricted antigen; isolating mRNA molecules from antibody producing cells of said non-human mammal; producing a phage display library displaying protein molecules encoded by said mRNA molecules; and isolating at least one phage from said phage display library, said at least one phage displaying said antibody specifically binding to said human major histocompatibility complex (MHC) class I or II being complexed with said HLA-restricted antigen.
  • It is a further aspect of the invention to provide an antibody that specifically binds to a human major histocompatibility complex (MHC) class I or II being complexed with a HLA-restricted antigen, wherein the antibody preferably is a polyclonal antibody, monoclonal antibody, bi-specific antibody and/or a chimeric antibody.
  • Yet another aspect of the present invention then relates to a method of producing said antibody specifically binding to a human major histocompatibility complex (MHC) class I or II being complexed with a HLA-restricted antigen, the method comprising: immunizing a genetically engineered non-human mammal comprising cells expressing said human major histocompatibility complex (MHC) class I or II with a soluble form of a MHC class I or II molecule being complexed with said HLA-restricted antigen; isolating mRNA molecules from antibody producing cells of said non-human mammal; producing a phage display library displaying protein molecules encoded by said mRNA molecules; and isolating at least one phage from said phage display library, said at least one phage displaying said antibody specifically bindable to said human major histocompatibility complex (MHC) class I or II being complexed with said HLA-restricted antigen. Respective methods for producing such antibodies and single chain class I major histocompatibility complexes, as well as other tools for the production of these antibodies are disclosed in WO 03/068201, WO 2004/084798, WO 01/72768, WO 03/070752, and Cohen C J, et al.

  • Preferably, the antibody is binding with a binding affinity of below 20 nanomolar, preferably of below 10 nanomolar, to the complex, which is regarded as “specific” in the context of the present invention.
  • It is a further aspect of the invention to provide a method for producing a soluble T-cell receptor recognizing a specific peptide-MHC complex. Such soluble T-cell receptors can be generated from specific T-cell clones, and their affinity can be increased by mutagenesis targeting the complementarity-determining regions. For the purpose of T-cell receptor selection, phage display can be used (US 2010/0113300, Liddy N, et al. Monoclonal TCR-redirected tumor cell killing. Nat Med 2012 June;18(6):980-987). For the purpose of stabilization of T-cell receptors during phage display and in case of practical use as drug, alpha and beta chain can be linked e.g. by non-native disulfide bonds, other covalent bonds (single-chain T-cell receptor), or by dimerization domains (see Boulter J M, et al. Stable, soluble T-cell receptor molecules for crystallization and therapeutics. Protein Eng 2003 September; 16(9):707-711.; Card K F, et al. A soluble single-chain T-cell receptor IL-2 fusion protein retains MHC-restricted peptide specificity and IL-2 bioactivity. Cancer Immunol Immunother 2004 April; 53(4):345-357; and Willcox BE, et al. Production of soluble alphabeta T-cell receptor heterodimers suitable for biophysical analysis of ligand binding. Protein Sci 1999 November; 8 (11):2418-2423). The T-cell receptor can be linked to toxins, drugs, cytokines (see US 2013/0115191), domains recruiting effector cells such as an anti-CD3 domain, etc., in order to execute particular functions on target cells. Moreover, it could be expressed in T cells used for adoptive transfer.
  • Further information can be found in WO 2004/033685A1 and WO 2004/074322A1. A combination of sTCRs is described in WO 2012/056407A1. Further methods for the production are disclosed in WO 2013/057586A1.
  • In addition, they can be used to verify a pathologist's diagnosis of a cancer based on a biopsied sample.
  • In order to select over-presented peptides, a presentation profile is calculated showing the median sample presentation as well as replicate variation. The profile juxtaposes samples of the tumor entity of interest to a baseline of normal tissue samples. Each of these profiles can then be consolidated into an over-presentation score by calculating the p-value of a Linear Mixed-Effects Model (J. Pinheiro, et al. The nlme Package: Linear and Nonlinear Mixed Effects Models. 2007) adjusting for multiple testing by False Discovery Rate (Y. Benjamini and Y. Hochberg. Controlling the False Discovery Rate: A Practical and Powerful Approach to Multiple Testing. Journal of the Royal Statistical Society. Series B (Methodological), Vol.57 (No.1):289-300, 1995).
  • For the identification and relative quantitation of HLA ligands by mass spectrometry, HLA molecules from shock-frozen tissue samples were purified and HLA-associated peptides were isolated. The isolated peptides were separated and sequences were identified by online nano-electrospray-ionization (nanoESl) liquid chromatography-mass spectrometry (LC-MS) experiments. The resulting peptide sequences were verified by comparison of the fragmentation pattern of natural TUMAPs recorded from CLL samples with the fragmentation patterns of corresponding synthetic reference peptides of identical sequences. Since the peptides were directly identified as ligands of HLA molecules of primary tumors, these results provide direct evidence for the natural processing and presentation of the identified peptides on primary cancer tissue obtained from CLL patients.
  • The discovery pipeline XPRESIDENT® v2.1 (see, for example, US 2013-0096016, which is hereby incorporated by reference in its entirety) allows the identification and selection of relevant over-presented peptide vaccine candidates based on direct relative quantitation of HLA-restricted peptide levels on cancer tissues in comparison to several different non-cancerous tissues and organs. This was achieved by the development of label-free differential quantitation using the acquired LC-MS data processed by a proprietary data analysis pipeline, combining algorithms for sequence identification, spectral clustering, ion counting, retention time alignment, charge state deconvolution and normalization.
  • Presentation levels including error estimates for each peptide and sample were established. Peptides exclusively presented on tumor tissue and peptides over-presented in tumor versus non-cancerous tissues and organs have been identified.
  • HLA-peptide complexes from CLL tissue samples were purified and HLA-associated peptides were isolated and analysed by LC-MS (see examples). All TUMAPs contained in the present application were identified with this approach on primary CLL samples confirming their presentation on primary CLL.
  • All TUMAPs contained in the application at hand were identified with this approach on primary CLL samples confirming their presentation on primary CLL.
  • TUMAPs identified on multiple CLL tumor and normal tissues were quantified using ion-counting of label-free LC-MS data. The method assumes that LC-MS signal areas of a peptide correlate with its abundance in the sample. All quantitative signals of a peptide in various LC-MS experiments were normalized based on central tendency, averaged per sample and merged into a bar plot, called presentation profile. The presentation profile consolidates different analysis methods like protein database search, spectral clustering, charge state deconvolution (decharging) and retention time alignment and normalization.

  • The term “antibody” or “antibodies” is used herein in a broad sense and includes both polyclonal and monoclonal antibodies. In addition to intact or “full” immunoglobulin molecules, also included in the term “antibodies” are fragments or polymers of those immunoglobulin molecules and humanized versions of immunoglobulin molecules, so long as they exhibit any of the desired properties (e.g., specific binding of an CLL marker polypeptide, delivery of a toxin to an CLL (leukimea) cells expressing a CLL marker gene at an increased level, and/or inhibiting the activity of a CLL marker polypeptide) according to the invention.
  • Whenever possible, the antibodies of the invention may be purchased from commercial sources. The antibodies of the invention may also be generated using well-known methods. The skilled artisan will understand that either full length CLL marker polypeptides or fragments thereof may be used to generate the antibodies of the invention. A polypeptide to be used for generating an antibody of the invention may be partially or fully purified from a natural source, or may be produced using recombinant DNA techniques.
  • For example, a cDNA encoding a peptide according to the present invention, such as a peptide according to SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016 polypeptide, or a variant or fragment thereof, can be expressed in prokaryotic cells (e.g., bacteria) or eukaryotic cells (e.g., yeast, insect, or mammalian cells), after which the recombinant protein can be purified and used to generate a monoclonal or polyclonal antibody preparation that specifically bind the CLL marker polypeptide used to generate the antibody according to the invention.
  • One of skill in the art will realize that the generation of two or more different sets of monoclonal or polyclonal antibodies maximizes the likelihood of obtaining an antibody with the specificity and affinity required for its intended use (e.g., ELISA, immunohistochemistry, in vivo imaging, immunotoxin therapy). The antibodies are tested for their desired activity by known methods, in accordance with the purpose for which the antibodies are to be used (e.g., ELISA, immunohistochemistry, immunotherapy, etc.; for further guidance on the generation and testing of antibodies, see, e.g., Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1988, new 2nd edition 2013). For example, the antibodies may be tested in ELISA assays or Western blots. After their initial in vitro characterization, antibodies intended for therapeutic or in vivo diagnostic use are tested according to known clinical testing methods.
  • The term “monoclonal antibody” as used herein refers to an antibody obtained from a substantially homogeneous population of antibodies, i.e.; the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts. The monoclonal antibodies herein specifically include “chimeric” antibodies in which a portion of the heavy and/or light chain is identical with or homologous to corresponding sequences in antibodies derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, so long as they exhibit the desired antagonistic activity (U.S. Pat. No. 4,816,567, which is hereby incorporated in its entirety).
  • Monoclonal antibodies of the invention may be prepared using hybridoma methods. In a hybridoma method, a mouse or other appropriate host animal is typically immunized with an immunizing agent to elicit lymphocytes that produce or are capable of producing antibodies that will specifically bind to the immunizing agent. Alternatively, the lymphocytes may be immunized in vitro.
  • The monoclonal antibodies may also be made by recombinant DNA methods, such as those described in U.S. Pat. No. 4,816,567. DNA encoding the monoclonal antibodies of the invention can be readily isolated and sequenced using conventional procedures (e.g., by using oligonucleotide probes that are capable of binding specifically to genes encoding the heavy and light chains of murine antibodies).
  • In vitro methods are also suitable for preparing monovalent antibodies. Digestion of antibodies to produce fragments thereof, particularly, Fab fragments, can be accomplished using routine techniques known in the art. For instance, digestion can be performed using papain. Examples of papain digestion are described in WO 94/29348 and U.S. Pat. No. 4,342,566. Papain digestion of antibodies typically produces two identical antigen binding fragments, called Fab fragments, each with a single antigen binding site, and a residual Fc fragment. Pepsin treatment yields a a F(ab′)2 fragment and a pFc′ fragment.
  • The antibody fragments, whether attached to other sequences or not, can also include insertions, deletions, substitutions, or other selected modifications of particular regions or specific amino acids residues, provided the activity of the fragment is not significantly altered or impaired compared to the non-modified antibody or antibody fragment. These modifications can provide for some additional property, such as to remove/add amino acids capable of disulfide bonding, to increase its bio-longevity, to alter its secretory characteristics, etc. In any case, the antibody fragment must possess a bioactive property, such as binding activity, regulation of binding at the binding domain, etc. Functional or active regions of the antibody may be identified by mutagenesis of a specific region of the protein, followed by expression and testing of the expressed polypeptide. Such methods are readily apparent to a skilled practitioner in the art and can include site-specific mutagenesis of the nucleic acid encoding the antibody fragment.
  • The antibodies of the invention may further comprise humanized antibodies or human antibodies. Humanized forms of non-human (e.g., murine) antibodies are chimeric immunoglobulins, immunoglobulin chains or fragments thereof (such as Fv, Fab, Fab′ or other antigen-binding subsequences of antibodies) which contain minimal sequence derived from non-human immunoglobulin. Humanized antibodies include human immunoglobulins (recipient antibody) in which residues from a complementary determining region (CDR) of the recipient are replaced by residues from a CDR of a non-human species (donor antibody) such as mouse, rat or rabbit having the desired specificity, affinity and capacity. In some instances, Fv framework (FR) residues of the human immunoglobulin are replaced by corresponding non-human residues. Humanized antibodies may also comprise residues which are found neither in the recipient antibody nor in the imported CDR or framework sequences. In general, the humanized antibody will comprise substantially all of at least one, and typically two, variable domains, in which all or substantially all of the CDR regions correspond to those of a non-human immunoglobulin and all or substantially all of the FR regions are those of a human immunoglobulin consensus sequence. The humanized antibody optimally also will comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin.
  • Methods for humanizing non-human antibodies are well known in the art. Generally, a humanized antibody has one or more amino acid residues introduced into it from a source which is non-human. These non-human amino acid residues are often referred to as “import” residues, which are typically taken from an “import” variable domain. Humanization can be essentially performed by substituting rodent CDRs or CDR sequences for the corresponding sequences of a human antibody. Accordingly, such “humanized” antibodies are chimeric antibodies (U.S. Pat. No. 4,816,567), wherein substantially less than an intact human variable domain has been substituted by the corresponding sequence from a non-human species. In practice, humanized antibodies are typically human antibodies in which some CDR residues and possibly some FR residues are substituted by residues from analogous sites in rodent antibodies.
  • Transgenic animals (e.g., mice) that are capable, upon immunization, of producing a full repertoire of human antibodies in the absence of endogenous immunoglobulin production can be employed. For example, it has been described that the homozygous deletion of the antibody heavy chain joining region gene in chimeric and germ-line mutant mice results in complete inhibition of endogenous antibody production. Transfer of the human germ-line immunoglobulin gene array in such germ-line mutant mice will result in the production of human antibodies upon antigen challenge. Human antibodies can also be produced in phage display libraries.
  • Antibodies of the invention are preferably administered to a subject in a pharmaceutically acceptable carrier. Typically, an appropriate amount of a pharmaceutically-acceptable salt is used in the formulation to render the formulation isotonic. Examples of the pharmaceutically-acceptable carrier include saline, Ringer's solution and dextrose solution. The pH of the solution is preferably from about 5 to about 8, and more preferably from about 7 to about 7.5. Further carriers include sustained release preparations such as semipermeable matrices of solid hydrophobic polymers containing the antibody, which matrices are in the form of shaped articles, e.g., films, liposomes or microparticles. It will be apparent to those persons skilled in the art that certain carriers may be more preferable depending upon, for instance, the route of administration and concentration of antibody being administered.
  • The antibodies can be administered to the subject, patient, or cell by injection (e.g., intravenous, intraperitoneal, subcutaneous, intramuscular), or by other methods such as infusion that ensure its delivery to the bloodstream in an effective form. The antibodies may also be administered by intratumoral or peritumoral routes, to exert local as well as systemic therapeutic effects. Local or intravenous injection is preferred.
  • Effective dosages and schedules for administering the antibodies may be determined empirically, and making such determinations is within the skill in the art. Those skilled in the art will understand that the dosage of antibodies that must be administered will vary depending on, for example, the subject that will receive the antibody, the route of administration, the particular type of antibody used and other drugs being administered. A typical daily dosage of the antibody used alone might range from about 1 (μg/kg to up to 100 mg/kg of body weight or more per day, depending on the factors mentioned above. Following administration of an antibody for treating CLL, the efficacy of the therapeutic antibody can be assessed in various ways well known to the skilled practitioner. s secondary to CLL
  • Because the peptides as mentioned in the Tables above (specifically the ones associated with CLL) of the invention and thus their underlying polypeptides are highly expressed in CLL, and are expressed at rather to extremely low levels in normal cells, the inhibition of a protein selected from the group consisting of APOBEC3D, CDK14, RASGRF1, CDCA7L, CELSR1, AKAP2, CTDP1, DNMBP, TAGAP, ABCA6, DMXL1, PARP3, TP53I11, B4GALT1, IRF9, KDM2B, TBC1D22A, ZNF296, BACH2, PRR12, ZFAND5, ATP5G1, DMD, ARID5B, ZNF638, DDX46, RRM2B, BLNK, HSH2D, ERP44, METTL7A, ELP3, NLRP2, ZC3H12D, NELFE, ATP6V1C1, HLA-DMA, TUFM, EIF6, CKAP4, COBLL1, TMED4, TNFRSF13C, UBL7, CXorf21, ASUN, SL24D1, and TRAF3IP3 expression or of the activity thereof may be preferably integrated into a therapeutic strategy for treating or preventing CLL.
  • The principle of antisense therapy is based on the hypothesis that sequence-specific suppression of gene expression (via transcription or translation) may be achieved by intra-cellular hybridization between genomic DNA or mRNA and a complementary antisense species. The formation of such a hybrid nucleic acid duplex interferes with transcription of the target tumor antigen-encoding genomic DNA, or processing/transport/translation and/or stability of the target tumor antigen mRNA.
  • Antisense nucleic acids can be delivered by a variety of approaches. For example, antisense oligonucleotides or anti-sense RNA can be directly administered (e.g., by intravenous injection) to a subject in a form that allows uptake into tumor cells. Alternatively, viral or plasmid vectors that encode antisense RNA (or RNA fragments) can be introduced into cells in vivo. Antisense effects can also be induced by sense sequences; however, the extent of phenotypic changes is highly variable. Phenotypic changes induced by effective antisense therapy are assessed according to changes in, e.g., target mRNA levels, target protein levels, and/or target protein activity levels.
  • In a specific example, inhibition of CLL marker function by antisense gene therapy may be accomplished by direct administration of antisense lung tumor marker RNA to a subject. The antisense tumor marker RNA may be produced and isolated by any standard technique, but is most readily produced by in vitro transcription using an antisense tumor marker cDNA under the control of a high efficiency promoter (e.g., the
  • T7 promoter). Administration of anti-sense tumor marker RNA to cells can be carried out by any of the methods for direct nucleic acid administration described below.
  • An alternative strategy for inhibiting the function of a protein selected from the group consisting of APOBEC3D, CDK14, RASGRF1, CDCA7L, CELSR1, AKAP2, CTDP1, DNMBP, TAGAP, ABCA6, DMXL1, PARP3, TP53I11, B4GALT1, IRF9, KDM2B, TBC1D22A, ZNF296, BACH2, PRR12, ZFAND5, ATP5G1, DMD, ARID5B, ZNF638, DDX46, RRM2B, BLNK, HSH2D, ERP44, METTL7A, ELP3, NLRP2, ZC3H12D, NELFE, ATP6V1C1, HLA-DMA, TUFM, EIF6, CKAP4, COBLL1, TMED4, TNFRSF13C, UBL7, CXorf21, ASUN, SL24D1, and TRAF3IP3 using gene therapy involves intracellular expression of an anti-protein antibody or a portion of an anti-protein antibody. For example, the gene (or gene fragment) encoding a monoclonal antibody that specifically binds to a protein selected from the group consisting of APOBEC3D, CDK14, RASGRF1, CDCA7L, CELSR1, AKAP2, CTDP1, DNMBP, TAGAP, ABCA6, DMXL1, PARP3, TP53I11, B4GALT1, IRF9, KDM2B, TBC1D22A, ZNF296, BACH2, PRR12, ZFAND5, ATP5G1, DMD, ARID5B, ZNF638, DDX46, RRM2B, BLNK, HSH2D, ERP44, METTL7A, ELP3, NLRP2, ZC3H12D, NELFE, ATP6V1C1, HLA-DMA, TUFM, EIF6, CKAP4, COBLL1, TMED4, TNFRSF13C, UBL7, CXorf21, ASUN, SL24D1, and TRAF3IP3 and inhibits its biological activity is placed under the transcriptional control of a specific (e.g., tissue- or tumor-specific) gene regulatory sequence, within a nucleic acid expression vector. The vector is then administered to the subject such that it is taken up by CLL cells or other cells, which then secrete the anti-protein antibody, and thereby block biological activity of the respective polypeptide. Preferably, proteins are present on the cellular surface of CLL cancer cells.
  • In the methods described above, which include the administration and uptake of exogenous DNA into the cells of a subject (i.e., gene transduction or transfection), the nucleic acids of the present invention can be in the form of naked DNA or the nucleic acids can be in a vector for delivering the nucleic acids to the cells for inhibition of CLL tumor marker protein expression. The vector can be a commercially available preparation, such as an adenovirus vector (Quantum Biotechnologies, Inc. (Laval, Quebec, Canada). Delivery of the nucleic acid or vector to cells can be via a variety of mechanisms. As one example, delivery can be via a liposome, using commercially available liposome preparations such as LIPOFECTIN, LIPOFECTAMINE (GIBCO-25 BRL, Inc., Gaithersburg, Md.), SUPERFECT (Qiagen, Inc. Hilden, Germany) and TRANSFECTAM (Promega Biotec, Inc., Madison, Wis., US), as well as other liposomes developed according to procedures standard in the art. In addition, the nucleic acid or vector of this invention can be delivered in vivo by electroporation, the technology for which is available from Genetronics, Inc. (San Diego, US) as well as by means of a SONOPORATION machine (ImaRx Pharmaceutical Corp., Tucson, Arizona, US).
  • As one example, vector delivery can be via a viral system, such as a retroviral vector system that can package a recombinant retroviral genome. The recombinant retrovirus can then be used to infect and thereby deliver to the infected cells antisense nucleic acid that inhibits expression of a protein selected from the group consisting of APOBEC3D, CDK14, RASGRF1, CDCA7L, CELSR1, AKAP2, CTDP1, DNMBP, TAGAP, ABCA6, DMXL1, PARP3, TP53I11, B4GALT1, IRF9, KDM2B, TBC1D22A, ZNF296, BACH2, PRR12, ZFAND5, ATP5G1, DMD, ARID5B, ZNF638, DDX46, RRM2B, BLNK, HSH2D, ERP44, METTL7A, ELP3, NLRP2, ZC3H12D, NELFE, ATP6V1C1, HLA-DMA, TUFM, EIF6, CKAP4, COBLL1, TMED4, TNFRSF13C, UBL7, CXorf21, ASUN, SL24D1, and TRAF3IP3. The exact method of introducing the altered nucleic acid into mammalian cells is, of course, not limited to the use of retroviral vectors. Other techniques are widely available for this procedure including the use of adenoviral vectors, adeno-associated viral (AAV) vectors, lentiviral vectors, pseudotyped retroviral vectors. Physical transduction techniques can also be used, such as liposome delivery and receptor-mediated and other endocytosis mechanisms. This invention can be used in conjunction with any of these or other commonly used gene transfer methods.
  • The antibodies may also be used for in vivo diagnostic assays. Generally, the antibody is labeled with a radionucleotide (such as 111In, 99Tc, 14C, 131I, 3H, 32P or 35S) so that the tumor can be localized using immunoscintiography. In one embodiment, antibodies or fragments thereof bind to the extracellular domains of two or more targets of a protein selected from the group consisting of APOBEC3D, CDK14, RASGRF1, CDCA7L, CELSR1, AKAP2, CTDP1, DNMBP, TAGAP, ABCA6, DMXL1, PARP3, TP53I11, B4GALT1, IRF9, KDM2B, TBC1D22A, ZNF296, BACH2, PRR12, ZFAND5, ATP5G1, DMD, ARID5B, ZNF638, DDX46, RRM2B, BLNK, HSH2D, ERP44, METTL7A, ELP3, NLRP2, ZC3H12D, NELFE, ATP6V1C1, HLA-DMA, TUFM, EIF6, CKAP4, COBLL1, TMED4, TNFRSF13C, UBL7, CXorf21, ASUN, SL24D1, and TRAF3IP3, and the affinity value (Kd) is less than 1×10 μM.
  • Antibodies for diagnostic use may be labeled with probes suitable for detection by various imaging methods. Methods for detection of probes include, but are not limited to, fluorescence, light, confocal and electron microscopy; magnetic resonance imaging and spectroscopy; fluoroscopy, computed tomography and positron emission tomography. Suitable probes include, but are not limited to, fluorescein, rhodamine, eosin and other fluorophores, radioisotopes, gold, gadolinium and other lanthanides, paramagnetic iron, fluorine-18 and other positron-emitting radionuclides. Additionally, probes may be bi- or multi-functional and be detectable by more than one of the methods listed. These antibodies may be directly or indirectly labeled with said probes. Attachment of probes to the antibodies includes covalent attachment of the probe, incorporation of the probe into the antibody, and the covalent attachment of a chelating compound for binding of probe, amongst others well recognized in the art. For immunohistochemistry, the disease tissue sample may be fresh or frozen or may be embedded in paraffin and fixed with a preservative such as formalin. The fixed or embedded section contains the sample are contacted with a labeled primary antibody and secondary antibody, wherein the antibody is used to detect the expression of the proteins in situ.
  • The present invention thus provides a peptide comprising a sequence that is selected from the group of consisting of SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016 or a variant thereof which is 90% homologous to SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016, or a variant thereof that will induce T cells cross-reacting with said peptide.
  • The peptides of the invention have the ability to bind to a molecule of the human major histocompatibility complex (MHC) class-I and/or class II.
  • In the present invention, the term “homologous” refers to the degree of identity (see Percent Identity above) between sequences of two amino acid sequences, i.e. peptide or polypeptide sequences. The aforementioned “homology” is determined by comparing two sequences aligned under optimal conditions over the sequences to be compared. Such a sequence homology can be calculated by creating an alignment using, for example, the ClustalW algorithm. Commonly available sequence analysis software, more specifically, Vector NTI, GENETYX or other analysis tools are provided by public databases.
  • A person skilled in the art will be able to assess, whether T cells induced by a variant of a specific peptide will be able to cross-react with the peptide itself (Fong L, et al. Altered peptide ligand vaccination with Flt3 ligand expanded dendritic cells for tumor immunotherapy. Proc Natl Acad Sci USA. 2001 Jul. 17; 98(15):8809-14; Zaremba S, et al. Identification of an enhancer agonist cytotoxic T lymphocyte peptide from human carcinoembryonic antigen. Cancer Res. 1997 Oct. 15; 57(20):4570-7; Colombetti S, et al. Impact of orthologous melan-A peptide immunizations on the anti-self melan-A/HLA-A2 T cell cross-reactivity. J Immunol. 2006 Jun. 1; 176(11):6560-7; Appay V, et al. Decreased specific CD8+ T cell cross-reactivity of antigen recognition following vaccination with Melan-A peptide. Eur J Immunol. 2006 July; 36(7):1805-14).
  • By a “variant” of the given amino acid sequence the inventors mean that the side chains of, for example, one or two of the amino acid residues are altered (for example by replacing them with the side chain of another naturally occurring amino acid residue or some other side chain) such that the peptide is still able to bind to an HLA molecule in substantially the same way as a peptide consisting of the given amino acid sequence in consisting of SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016. For example, a peptide may be modified so that it at least maintains, if not improves, the ability to interact with and bind to the binding groove of a suitable MHC molecule, such as HLA-A*02 or -DR, and in that way it at least maintains, if not improves, the ability to bind to the TCR of activated CTL.
  • These CTL can subsequently cross-react with cells and kill cells that express a polypeptide that contains the natural amino acid sequence of the cognate peptide as defined in the aspects of the invention. As can be derived from the scientific literature (Godkin A, et al. Use of eluted peptide sequence data to identify the binding characteristics of peptides to the insulin-dependent diabetes susceptibility allele HLA-DQ8 (DQ 3.2). Int Immunol. 1997 Jun;9(6):905-11) and databases (Rammensee H. et al. SYFPEITHI: database for MHC ligands and peptide motifs. Immunogenetics. 1999 November; 50(3-4):213-9), certain positions of HLA binding peptides are typically anchor residues forming a core sequence fitting to the binding motif of the HLA receptor, which is defined by polar, electrophysical, hydrophobic and spatial properties of the polypeptide chains constituting the binding groove. Thus, one skilled in the art would be able to modify the amino acid sequences set forth in SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016, by maintaining the known anchor residues, and would be able to determine whether such variants maintain the ability to bind MHC class I or II molecules. The variants of the present invention retain the ability to bind to the TCR of activated CTL, which can subsequently cross-react with—and kill cells that express a polypeptide containing the natural amino acid sequence of the cognate peptide as defined in the aspects of the invention.
  • The amino acid residues that do not substantially contribute to interactions with the T-cell receptor can be modified by replacement with another amino acid whose incorporation does not substantially affect T-cell reactivity and does not eliminate binding to the relevant MHC. Thus, apart from the proviso given, the peptide of the invention may be any peptide (by which term the inventors include oligopeptide or polypeptide), which includes the amino acid sequences or a portion or variant thereof as given.
  • Longer peptides may also be suitable. It is also possible, that MHC class I epitopes, although usually between 8 and 11 amino acids long, are generated by peptide processing from longer peptides or proteins that include the actual epitope. It is preferred that the residues that flank the actual epitope are residues that do not substantially affect proteolytic cleavage necessary to expose the actual epitope during processing.
  • Accordingly, the present invention also provides peptides and variants of MHC class I epitopes wherein the peptide or variant has an overall length of between 8 and 100, preferably between 8 and 30, and most preferred between 8 and 14, namely 8, 9, 10, 11, 12, 13, 14 amino acids, in case of the class II binding peptides the length can also be 15, 16, 17, 18, 19, 20, 21 or 22 amino acids.
  • Of course, the peptide or variant according to the present invention will have the ability to bind to a molecule of the human major histocompatibility complex (MHC) class I. Binding of a peptide or a variant to a MHC complex may be tested by methods known in the art.
  • In a particularly preferred embodiment of the invention the peptide consists or consists essentially of an amino acid sequence according to SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016.
  • “Consisting essentially of” shall mean that a peptide according to the present invention, in addition to the sequence according to any of SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226: to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016 or a variant thereof contains additional N- and/or C-terminally located stretches of amino acids that are not necessarily forming part of the peptide that functions as an epitope for MHC molecules epitope.
  • Nevertheless, these stretches can be important to provide an efficient introduction of the peptide according to the present invention into the cells. In one embodiment of the present invention, the peptide is a fusion protein which comprises, for example, the 80 N-terminal amino acids of the HLA-DR antigen-associated invariant chain (p33, in the following “li”) as derived from the NCBI, GenBank Accession number X00497. In other fusions, the peptides of the present invention can be fused to an antibody as described herein, or a functional part thereof, in particular into a sequence of an antibody, so as to be specifically targeted by said antibody, or, for example, to or into an antibody that is specific for dendritic cells.
  • In addition, the peptide or variant may be modified further to improve stability and/or binding to MHC molecules in order to elicit a stronger immune response. Methods for such an optimization of a peptide sequence are well known in the art and include, for example, the introduction of reverse peptide bonds or non-peptide bonds.
  • In a reverse peptide bond amino acid residues are not joined by peptide (—CO—NH—) linkages but the peptide bond is reversed. Such retro-inverso peptidomimetics may be made using methods known in the art, for example such as those described in Meziere et al (1997) J. Immunol. 159, 3230-3237, incorporated herein by reference. This approach involves making pseudopeptides containing changes involving the backbone, and not the orientation of side chains. Meziere et al (1997) show that for MHC binding and T helper cell responses, these pseudopeptides are useful. Retro-inverse peptides, which contain NH—CO bonds instead of CO—NH peptide bonds, are much more resistant to proteolysis.
  • A non—peptide bond is, for example, —CH2—NH, —CH2S—, —CH2CH2—, —CH═CH—, —COCH2—, —CH(OH)CH2—, and —CH2SO—. U.S. Pat. No. 4,897,445 provides a method for the solid phase synthesis of non-peptide bonds (—CH2—NH) in polypeptide chains which involves polypeptides synthesized by standard procedures and the non-peptide bond synthesized by reacting an amino aldehyde and an amino acid in the presence of NaCNBH3.
  • Peptides comprising the sequences described above may be synthesized with additional chemical groups present at their amino and/or carboxy termini, to enhance the stability, bioavailability, and/or affinity of the peptides. For example, hydrophobic groups such as carbobenzoxyl, dansyl, or t-butyloxycarbonyl groups may be added to the peptides' amino termini. Likewise, an acetyl group or a 9-fluorenylmethoxy-carbonyl group may be placed at the peptides' amino termini. Additionally, the hydrophobic group, t-butyloxycarbonyl, or an amido group may be added to the peptides' carboxy termini.
  • Further, the peptides of the invention may be synthesized to alter their steric configuration. For example, the D-isomer of one or more of the amino acid residues of the peptide may be used, rather than the usual L-isomer. Still further, at least one of the amino acid residues of the peptides of the invention may be substituted by one of the well-known non-naturally occurring amino acid residues. Alterations such as these may serve to increase the stability, bioavailability and/or binding action of the peptides of the invention.
  • Similarly, a peptide or variant of the invention may be modified chemically by reacting specific amino acids either before or after synthesis of the peptide. Examples for such modifications are well known in the art and are summarized e.g. in R. Lundblad, Chemical Reagents for Protein Modification, 3rd ed. CRC Press, 2005, which is incorporated herein by reference. Chemical modification of amino acids includes but is not limited to, modification by acylation, amidination, pyridoxylation of lysine, reductive alkylation, trinitrobenzylation of amino groups with 2,4,6-trinitrobenzene sulphonic acid (TNBS), amide modification of carboxyl groups and sulphydryl modification by performic acid oxidation of cysteine to cysteic acid, formation of mercurial derivatives, formation of mixed disulphides with other thiol compounds, reaction with maleimide, carboxymethylation with iodoacetic acid or iodoacetamide and carbamoylation with cyanate at alkaline pH, although without limitation thereto. In this regard, the skilled person is referred to Chapter 15 of Current Protocols In Protein Science, Eds. Coligan et al. (John Wiley and Sons NY 1995-2000) for more extensive methodology relating to chemical modification of proteins.
  • Briefly, modification of e.g. arginyl residues in proteins is often based on the reaction of vicinal dicarbonyl compounds such as phenylglyoxal, 2,3-butanedione, and 1,2-cyclohexanedione to form an adduct. Another example is the reaction of methylglyoxal with arginine residues. Cysteine can be modified without concomitant modification of other nucleophilic sites such as lysine and histidine. As a result, a large number of reagents are available for the modification of cysteine. The websites of companies such as Sigma-Aldrich provide information on specific reagents.
  • Selective reduction of disulfide bonds in proteins is also common. Disulfide bonds can be formed and oxidized during the heat treatment of biopharmaceuticals.
  • Woodward's Reagent K may be used to modify specific glutamic acid residues. N-(3-(dimethylamino)propyl)-N′-ethylcarbodiimide can be used to form intra-molecular crosslinks between a lysine residue and a glutamic acid residue.
  • For example, diethylpyrocarbonate is a reagent for the modification of histidyl residues in proteins. Histidine can also be modified using 4-hydroxy-2-nonenal.
  • The reaction of lysine residues and other a-amino groups is, for example, useful in binding of peptides to surfaces or the cross-linking of proteins/peptides. Lysine is the site of attachment of poly(ethylene)glycol and the major site of modification in the glycosylation of proteins.
  • Methionine residues in proteins can be modified with e.g. iodoacetamide, bromoethylamine, and chloramine T.
  • Tetranitromethane and N-acetylimidazole can be used for the modification of tyrosyl residues. Cross-linking via the formation of dityrosine can be accomplished with hydrogen peroxide/copper ions.
  • Recent studies on the modification of tryptophan have used N-bromosuccinimide, 2-hydroxy-5-nitrobenzyl bromide or 3-bromo-3-methyl-2-(2-nitrophenylmercapto)-3H-indole (BPNS-skatole).
  • Successful modification of therapeutic proteins and peptides with PEG is often associated with an extension of circulatory half-life while cross-linking of proteins with glutaraldehyde, polyethyleneglycol diacrylate and formaldehyde is used for the preparation of hydrogels. Chemical modification of allergens for immunotherapy is often achieved by carbamylation with potassium cyanate.
  • A peptide or variant, wherein the peptide is modified or includes non-peptide bonds is a preferred embodiment of the invention. Generally, peptides and variants (at least those containing peptide linkages between amino acid residues) may be synthesized by the Fmoc-polyamide mode of solid-phase peptide synthesis as disclosed by Lukas et al. (Solid-phase peptide synthesis under continuous-flow conditions. Proc Natl Acad Sci USA. May 1981; 78(5): 2791-2795) and references therein. Temporary N-amino group protection is afforded by the 9-fluorenylmethyloxycarbonyl (Fmoc) group. Repetitive cleavage of this highly base-labile protecting group is done using 20% piperidine in N, N-dimethylformamide. Side-chain functionalities may be protected as their butyl ethers (in the case of serine threonine and tyrosine), butyl esters (in the case of glutamic acid and aspartic acid), butyloxycarbonyl derivative (in the case of lysine and histidine), trityl derivative (in the case of cysteine) and 4-methoxy-2,3,6-trimethylbenzenesulphonyl derivative (in the case of arginine). Where glutamine or asparagine are C-terminal residues, use is made of the 4,4′-dimethoxybenzhydryl group for protection of the side chain amido functionalities. The solid-phase support is based on a polydimethyl-acrylamide polymer constituted from the three monomers dimethylacrylamide (backbone-monomer), bisacryloylethylene diamine (cross linker) and acryloylsarcosine methyl ester (functionalizing agent). The peptide-to-resin cleavable linked agent used is the acid-labile 4-hydroxymethyl-phenoxyacetic acid derivative. All amino acid derivatives are added as their preformed symmetrical anhydride derivatives with the exception of asparagine and glutamine, which are added using a reversed N, N-dicyclohexyl-carbodiimide/1 hydroxybenzotriazole mediated coupling procedure. All coupling and deprotection reactions are monitored using ninhydrin, trinitrobenzene sulphonic acid or isotin test procedures. Upon completion of synthesis, peptides are cleaved from the resin support with concomitant removal of side-chain protecting groups by treatment with 95% trifluoroacetic acid containing a 50% scavenger mix. Scavengers commonly used include ethandithiol, phenol, anisole and water, the exact choice depending on the constituent amino acids of the peptide being synthesized. Also a combination of solid phase and solution phase methodologies for the synthesis of peptides is possible (see, for example, Bruckdorfer et al., 2004, and the references as cited therein).
  • Trifluoroacetic acid is removed by evaporation in vacuo, with subsequent trituration with diethyl ether affording the crude peptide. Any scavengers present are removed by a simple extraction procedure which on lyophilisation of the aqueous phase affords the crude peptide free of scavengers. Reagents for peptide synthesis are generally available from e.g. Calbiochem-Novabiochem (UK) Ltd, Nottingham NG7 2QJ, UK.
  • Purification may be performed by any one, or a combination of, techniques such as re-crystallization, size exclusion chromatography, ion-exchange chromatography, hydrophobic interaction chromatography and (usually) reverse-phase high performance liquid chromatography using e.g. acetonitril/water gradient separation.
  • Analysis of peptides may be carried out using thin layer chromatography, electrophoresis, in particular capillary electrophoresis, solid phase extraction (CSPE), reverse-phase high performance liquid chromatography, amino-acid analysis after acid hydrolysis and by fast atom bombardment (FAB) mass spectrometric analysis, as well as MALDI and ESI-Q-TOF mass spectrometric analysis.
  • A further aspect of the invention provides a nucleic acid (for example a polynucleotide) encoding a peptide or peptide variant of the invention. The polynucleotide may be, for example, DNA, cDNA, PNA, RNA or combinations thereof, either single- and/or double-stranded, or native or stabilized forms of polynucleotides, such as, for example, polynucleotides with a phosphorothioate backbone and it may or may not contain introns so long as it codes for the peptide. Of course, only peptides that contain naturally occurring amino acid residues joined by naturally occurring peptide bonds are encodable by a polynucleotide. A still further aspect of the invention provides an expression vector capable of expressing a polypeptide according to the invention.
  • A variety of methods have been developed to link polynucleotides, especially DNA, to vectors for example via complementary cohesive termini. For instance, complementary homopolymer tracts can be added to the DNA segment to be inserted to the vector DNA. The vector and DNA segment are then joined by hydrogen bonding between the complementary homopolymeric tails to form recombinant DNA molecules.
  • Synthetic linkers containing one or more restriction sites provide an alternative method of joining the DNA segment to vectors. Synthetic linkers containing a variety of restriction endonuclease sites are commercially available from a number of sources including International Biotechnologies Inc. New Haven, Conn., USA.
  • A desirable method of modifying the DNA encoding the polypeptide of the invention employs the polymerase chain reaction as disclosed by Saiki R K, et al. (Diagnosis of sickle cell anemia and beta-thalassemia with enzymatically amplified DNA and nonradioactive allele-specific oligonucleotide probes. N Engl J Med. 1988 Sep. 1; 319(9):537-41). This method may be used for introducing the DNA into a suitable vector, for example by engineering in suitable restriction sites, or it may be used to modify the DNA in other useful ways as is known in the art. If viral vectors are used, pox- or adenovirus vectors are preferred.
  • The DNA (or in the case of retroviral vectors, RNA) may then be expressed in a suitable host to produce a polypeptide comprising the peptide or variant of the invention. Thus, the DNA encoding the peptide or variant of the invention may be used in accordance with known techniques, appropriately modified in view of the teachings contained herein, to construct an expression vector, which is then used to transform an appropriate host cell for the expression and production of the polypeptide of the invention. Such techniques include those disclosed in U.S. Pat. Nos. 4,440,859, 4,530,901, 4,582,800, 4,677,063, 4,678,751, 4,704,362, 4,710,463, 4,757,006, 4,766,075, and 4,810,648.
  • The DNA (or in the case of retroviral vectors, RNA) encoding the polypeptide constituting the compound of the invention may be joined to a wide variety of other DNA sequences for introduction into an appropriate host. The companion DNA will depend upon the nature of the host, the manner of the introduction of the DNA into the host, and whether episomal maintenance or integration is desired.
  • Generally, the DNA is inserted into an expression vector, such as a plasmid, in proper orientation and correct reading frame for expression. If necessary, the DNA may be linked to the appropriate transcriptional and translational regulatory control nucleotide sequences recognized by the desired host, although such controls are generally available in the expression vector. The vector is then introduced into the host through standard techniques. Generally, not all of the hosts will be transformed by the vector. Therefore, it will be necessary to select for transformed host cells. One selection technique involves incorporating into the expression vector a DNA sequence, with any necessary control elements, that codes for a selectable trait in the transformed cell, such as antibiotic resistance.
  • Alternatively, the gene for such selectable trait can be on another vector, which is used to co-transform the desired host cell.
  • Host cells that have been transformed by the recombinant DNA of the invention are then cultured for a sufficient time and under appropriate conditions known to those skilled in the art in view of the teachings disclosed herein to permit the expression of the polypeptide, which can then be recovered.
  • Many expression systems are known, including bacteria (for example E. coli and Bacillus subtilis), yeasts (for example Saccharomyces cerevisiae), filamentous fungi (for example Aspergillus spec.), plant cells, animal cells and insect cells. Preferably, the system can be mammalian cells such as CHO cells available from the ATCC Cell Biology Collection.
  • A typical mammalian cell vector plasmid for constitutive expression comprises the CMV or SV40 promoter with a suitable poly A tail and a resistance marker, such as neomycin. One example is pSVL available from Pharmacia, Piscataway, N.J., USA. An example of an inducible mammalian expression vector is pMSG, also available from Pharmacia. Useful yeast plasmid vectors are pRS403-406 and pRS413-416 and are generally available from Stratagene Cloning Systems, La Jolla, Calif. 92037, USA. Plasmids pRS403, pRS404, pRS405 and pRS406 are Yeast Integrating plasmids (Ylps) and incorporate the yeast selectable markers HIS3, TRP1, LEU2 and URA3. Plasmids pRS413-416 are Yeast Centromere plasmids (Ycps). CMV promoter-based vectors (for example from Sigma-Aldrich) provide transient or stable expression, cytoplasmic expression or secretion, and N-terminal or C-terminal tagging in various combinations of FLAG, 3×FLAG, c-myc or MAT. These fusion proteins allow for detection, purification and analysis of recombinant protein. Dual-tagged fusions provide flexibility in detection.
  • The strong human cytomegalovirus (CMV) promoter regulatory region drives constitutive protein expression levels as high as 1 mg/L in COS cells. For less potent cell lines, protein levels are typically ˜0.1 mg/L. The presence of the SV40 replication origin will result in high levels of DNA replication in SV40 replication permissive COS cells. CMV vectors, for example, can contain the pMB1 (derivative of pBR322) origin for replication in bacterial cells, the b-lactamase gene for ampicillin resistance selection in bacteria, hGH polyA, and the f1 origin. Vectors containing the preprotrypsin leader (PPT) sequence can direct the secretion of FLAG fusion proteins into the culture medium for purification using ANTI-FLAG antibodies, resins, and plates. Other vectors and expression systems are well known in the art for use with a variety of host cells.
  • In another embodiment two or more peptides or peptide variants of the invention are encoded and thus expressed in a successive order (similar to “beads on a string” constructs). In doing so, the peptides or peptide variants may be linked or fused together by stretches of linker amino acids, such as for example LLLLLL, or may be linked without any additional peptide(s) between them.
  • The present invention also relates to a host cell transformed with a polynucleotide vector construct of the present invention. The host cell can be either prokaryotic or eukaryotic. Bacterial cells may be preferred prokaryotic host cells in some circumstances and typically are a strain of E. coli such as, for example, the E. coli strains DH5 available from Bethesda Research Laboratories Inc., Bethesda, Md., USA, and RR1 available from the American Type Culture Collection (ATCC) of Rockville, Md., USA (No ATCC 31343). Preferred eukaryotic host cells include yeast, insect and mammalian cells, preferably vertebrate cells such as those from a mouse, rat, monkey or human fibroblastic and colon cell lines. Yeast host cells include YPH499, YPH500 and YPH501, which are generally available from Stratagene Cloning Systems, La Jolla, Calif. 92037, USA. Preferred mammalian host cells include Chinese hamster ovary (CHO) cells available from the ATCC as CCL61, NIH Swiss mouse embryo cells NIH/3T3 available from the ATCC as CRL 1658, monkey kidney-derived COS-1 cells available from the ATCC as CRL 1650 and 293 cells which are human embryonic kidney cells. Preferred insect cells are Sf9 cells which can be transfected with baculovirus expression vectors. An overview regarding the choice of suitable host cells for expression can be found in, for example, the textbook of Paulina Balbá s and Argelia Lorence “Methods in Molecular Biology Recombinant Gene Expression, Reviews and Protocols,” Part One, Second Edition, ISBN 978-1-58829-262-9, and other literature known to the person of skill.
  • Transformation of appropriate cell hosts with a DNA construct of the present invention is accomplished by well-known methods that typically depend on the type of vector used. With regard to transformation of prokaryotic host cells, see, for example, Cohen et al (1972) Proc. Natl. Acad. Sci. USA 69, 2110, and Sambrook et al (1989) Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. Transformation of yeast cells is described in Sherman et al (1986) Methods In Yeast Genetics, A Laboratory Manual, Cold Spring Harbor, N.Y. The method of Beggs (1978) Nature 275,104-109 is also useful. With regard to vertebrate cells, reagents useful in transfecting such cells, for example calcium phosphate and DEAE-dextran or liposome formulations, are available from Stratagene Cloning Systems, or Life Technologies Inc., Gaithersburg, Md. 20877, USA. Electroporation is also useful for transforming and/or transfecting cells and is well known in the art for transforming yeast cell, bacterial cells, insect cells and vertebrate cells.
  • Successfully transformed cells, i.e. cells that contain a DNA construct of the present invention, can be identified by well-known techniques such as PCR. Alternatively, the presence of the protein in the supernatant can be detected using antibodies.
  • It will be appreciated that certain host cells of the invention are useful in the preparation of the peptides of the invention, for example bacterial, yeast and insect cells. However, other host cells may be useful in certain therapeutic methods. For example, antigen-presenting cells, such as dendritic cells, may usefully be used to express the peptides of the invention such that they may be loaded into appropriate MHC molecules. Thus, the current invention provides a host cell comprising a nucleic acid or an expression vector according to the invention.
  • In a preferred embodiment the host cell is an antigen presenting cell, in particular a dendritic cell or antigen presenting cell. APCs loaded with a recombinant fusion protein containing prostatic acid phosphatase (PAP) were approved by the U.S. Food and Drug Administration (FDA) on Apr. 29, 2010, to treat asymptomatic or minimally symptomatic metastatic HRPC (Sipuleucel-T) (Small E J, et al. Placebo-controlled phase III trial of immunologic therapy with sipuleucel-T (APC8015) in patients with metastatic, asymptomatic hormone refractory prostate cancer. J Clin Oncol. 2006 Jul. 1; 24(19):3089-94. Rini et al. Combination immunotherapy with prostatic acid phosphatase pulsed antigen-presenting cells (provenge) plus bevacizumab in patients with serologic progression of prostate cancer after definitive local therapy. Cancer. 2006 Jul. 1; 107(1):67-74).
  • A further aspect of the invention provides a method of producing a peptide or its variant, the method comprising culturing a host cell and isolating the peptide from the host cell or its culture medium.
  • In another embodiment the peptide, the nucleic acid or the expression vector of the invention are used in medicine. For example, the peptide or its variant may be prepared for intravenous (i.v.) injection, sub-cutaneous (s.c.) injection, intradermal (i.d.) injection, intraperitoneal (i.p.) injection, intramuscular (i.m.) injection. Preferred methods of peptide injection include s.c., i.d., i.p., i.m., and i.v. Preferred methods of DNA injection include i.d., i.m., s.c., i.p. and i.v. Doses of e.g. between 50 μg and 1.5 mg, preferably 125 μg to 500 μg, of peptide or DNA may be given and will depend on the respective peptide or DNA. Dosages of this range were successfully used in previous trials (Walter et al Nature Medicine 18, 1254-1261 (2012)).
  • Another aspect of the present invention includes an in vitro method for producing activated T cells, the method comprising contacting in vitro T cells with antigen loaded human MHC molecules expressed on the surface of a suitable antigen-presenting cell for a period of time sufficient to activate the T cell in an antigen specific manner, wherein the antigen is a peptide according to the invention. Preferably a sufficient amount of the antigen is used with an antigen-presenting cell.
  • Preferably the mammalian cell lacks or has a reduced level or function of the TAP peptide transporter. Suitable cells that lack the TAP peptide transporter include T2, RMA-S and Drosophila cells. TAP is the transporter associated with antigen processing.
  • The human peptide loading deficient cell line T2 is available from the American Type Culture Collection, 12301 Parklawn Drive, Rockville, Md. 20852, USA under Catalogue No CRL 1992; the Drosophila cell line Schneider line 2 is available from the ATCC under Catalogue No CRL 19863; the mouse RMA-S cell line is described in Karre et al 1985 (Ljunggren, H.-G., and K. Karre. 1985. J. Exp. Med. 162:1745).
  • Preferably, the host cell before transfection expresses substantially no MHC class I molecules. It is also preferred that the stimulator cell expresses a molecule important for providing a co-stimulatory signal for T-cells such as any of B7.1, B7.2, ICAM-1 and LFA 3. The nucleic acid sequences of numerous MHC class I molecules and of the co-stimulator molecules are publicly available from the GenBank and EMBL databases.
  • In case of a MHC class I epitope being used as an antigen, the T cells are CD8-positive CTLs.
  • If an antigen-presenting cell is transfected to express such an epitope, preferably the cell comprises an expression vector capable of expressing a peptide containing SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016, or a variant amino acid sequence thereof.
  • A number of other methods may be used for generating CTL in vitro. For example, autologous tumor-infiltrating lymphocytes can be used in the generation of CTL. Plebanski et al (1995) (Induction of peptide-specific primary cytotoxic T lymphocyte responses from human peripheral blood.Eur J Immunol. 1995 Jun.; 25(6):1783-7) make use of autologous peripheral blood lymphocytes (PLBs) in the preparation of CTL. Furthermore, the production of autologous CTL by pulsing dendritic cells with peptide or polypeptide, or via infection with recombinant virus is possible. Also, B cells can be used in the production of autologous CTL. In addition, macrophages pulsed with peptide or polypeptide, or infected with recombinant virus, may be used in the preparation of autologous CTL. S. Walter et al. 2003 (Cutting edge: predetermined avidity of human CD8 T cells expanded on calibrated MHC/anti-CD28-coated microspheres.J Immunol. 2003 Nov. 15; 171(10):4974-8) describe the in vitro priming of T cells by using artificial antigen presenting cells (aAPCs), which is also a suitable way for generating T cells against the peptide of choice. In the present invention, aAPCs were generated by the coupling of preformed MHC:peptide complexes to the surface of polystyrene particles (microbeads) by biotin:streptavidin biochemistry. This system permits the exact control of the MHC density on aAPCs, which allows to selectively elicit high- or low-avidity antigen-specific T cell responses with high efficiency from blood samples. Apart from MHC:peptide complexes, aAPCs should carry other proteins with co-stimulatory activity like anti-CD28 antibodies coupled to their surface. Furthermore such aAPC-based systems often require the addition of appropriate soluble factors, e. g. cytokines, like interleukin-12.
  • Allogeneic cells may also be used in the preparation of T cells and a method is described in detail in WO 97/26328, incorporated herein by reference. For example, in addition to Drosophila cells and T2 cells, other cells may be used to present antigens such as CHO cells, baculovirus-infected insect cells, bacteria, yeast, vaccinia-infected target cells. In addition plant viruses may be used (see, for example, Porta et al. (1994) Development of cowpea mosaic virus as a high-yielding system for the presentation of foreign peptides.Virology. 1994 Aug. 1; 202(2):949-55) which describes the development of cowpea mosaic virus as a high-yielding system for the presentation of foreign peptides.
  • The activated T cells that are directed against the peptides of the invention are useful in therapy. Thus, a further aspect of the invention provides activated T cells obtainable by the foregoing methods of the invention.
  • Activated T cells, which are produced by the above method, will selectively recognize a cell that aberrantly expresses a polypeptide that comprises an amino acid sequence of SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016.
  • Preferably, the T cell recognizes the cell by interacting through its TCR with the HLA/peptide-complex (for example, binding). The T cells are useful in a method of killing target cells in a patient whose target cells aberrantly express a polypeptide comprising an amino acid sequence of the invention wherein the patient is administered an effective number of the activated T cells. The T cells that are administered to the patient may be derived from the patient and activated as described above (i.e. they are autologous T cells). Alternatively, the T cells are not from the patient but are from another individual. Of course, it is preferred if the individual is a healthy individual. By “healthy individual” the inventors mean that the individual is generally in good health, preferably has a competent immune system and, more preferably, is not suffering from any disease that can be readily tested for, and detected.
  • In vivo, the target cells for the CD8-positive T cells according to the present invention can be cells of the tumor (which sometimes express MHC class II) and/or stromal cells surrounding the tumor (tumor cells) (which sometimes also express MHC class II; (Dengjel et al., 2006)).
  • The T cells of the present invention may be used as active ingredients of a therapeutic composition. Thus, the invention also provides a method of killing target cells in a patient whose target cells aberrantly express a polypeptide comprising an amino acid sequence of the invention, the method comprising administering to the patient an effective number of T cells as defined above.
  • By “aberrantly expressed” the inventors also mean that the polypeptide is over-expressed compared to normal levels of expression or that the gene is silent in the tissue from which the tumor is derived but in the tumor it is expressed. By “over-expressed” the inventors mean that the polypeptide is present at a level at least 1.2-fold of that present in normal tissue; preferably at least 2-fold, and more preferably at least 5-fold or 10-fold the level present in normal tissue.
  • T cells may be obtained by methods known in the art, e.g. those described above.
  • Protocols for this so-called adoptive transfer of T cells are well known in the art. Reviews can be found in: Gattinoni L, et al. Adoptive immunotherapy for cancer: building on success. Nat Rev Immunol. 2006 May; 6(5):383-93. Review. and Morgan RA, et al. Cancer regression in patients after transfer of genetically engineered lymphocytes. Science. 2006 Oct. 6; 314(5796):126-9).
  • Any molecule of the invention, i.e. the peptide, nucleic acid, antibody, expression vector, cell, activated CTL, T-cell receptor or the nucleic acid encoding it is useful for the treatment of disorders, characterized by cells escaping an immune response. Therefore any molecule of the present invention may be used as medicament or in the manufacture of a medicament. The molecule may be used by itself or combined with other molecule(s) of the invention or (a) known molecule(s).
  • Preferably, the medicament of the present invention is a vaccine. It may be administered directly into the patient, into the affected organ or systemically i.d., i.m., s.c., i.p. and i.v., or applied ex vivo to cells derived from the patient or a human cell line which are subsequently administered to the patient, or used in vitro to select a subpopulation of immune cells derived from the patient, which are then re-administered to the patient. If the nucleic acid is administered to cells in vitro, it may be useful for the cells to be transfected so as to co-express immune-stimulating cytokines, such as interleukin-2. The peptide may be substantially pure, or combined with an immune-stimulating adjuvant (see below) or used in combination with immune-stimulatory cytokines, or be administered with a suitable delivery system, for example liposomes. The peptide may also be conjugated to a suitable carrier such as keyhole limpet haemocyanin (KLH) or mannan (see WO 95/18145 and Longenecker, 1993). The peptide may also be tagged, may be a fusion protein, or may be a hybrid molecule. The peptides whose sequence is given in the present invention are expected to stimulate CD4 or CD8 T cells. However, stimulation of CD8 CTLs is more efficient in the presence of help provided by CD4 T-helper cells. Thus, for MHC Class I epitopes that stimulate CD8 CTL the fusion partner or sections of a hybrid molecule suitably provide epitopes which stimulate CD4-positive T cells. CD4- and CD8-stimulating epitopes are well known in the art and include those identified in the present invention.
  • In one aspect, the vaccine comprises at least one peptide having the amino acid sequence set forth SEQ ID No. 1 to SEQ ID No. 1016, and at least one additional peptide, preferably two to 50, more preferably two to 25, even more preferably two to 20 and most preferably two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen or eighteen peptides. The peptide(s) may be derived from one or more specific TAAs and may bind to MHC class I molecules.
  • In another aspect, the vaccine comprises at least one peptide having the amino acid sequence set forth in SEQ ID NO: 1 to SEQ ID NO: 225, SEQ ID NO: 226 to SEQ ID NO: 542 or SEQ ID NO: 543 to SEQ ID NO: 1016, and at least one additional peptide, preferably two to 50, more preferably two to 25, even more preferably two to 20 and most preferably two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen or eighteen peptides. The peptide(s) may be derived from one or more specific TAAs and may bind to MHC class I molecules.
  • The polynucleotide may be substantially pure, or contained in a suitable vector or delivery system. The nucleic acid may be DNA, cDNA, PNA, RNA or a combination thereof. Methods for designing and introducing such a nucleic acid are well known in the art. An overview is provided by e.g. (Pascolo et al., Human peripheral blood mononuclear cells transfected with messenger RNA stimulate antigen-specific cytotoxic T-lymphocytes in vitro.Cell Mol Life Sci. 2005 August; 62(15):1755-62). Polynucleotide vaccines are easy to prepare, but the mode of action of these vectors in inducing an immune response is not fully understood. Suitable vectors and delivery systems include viral DNA and/or RNA, such as systems based on adenovirus, vaccinia virus, retroviruses, herpes virus, adeno-associated virus or hybrids containing elements of more than one virus. Non-viral delivery systems include cationic lipids and cationic polymers and are well known in the art of DNA delivery. Physical delivery, such as via a “gene-gun” may also be used. The peptide or peptides encoded by the nucleic acid may be a fusion protein, for example with an epitope that stimulates T cells for the respective opposite CDR as noted above.
  • The medicament of the invention may also include one or more adjuvants. Adjuvants are substances that non-specifically enhance or potentiate the immune response (e.g., immune responses mediated by CTLs and helper-T (TH) cells to an antigen, and would thus be considered useful in the medicament of the present invention. Suitable adjuvants include, but are not limited to, 1018 ISS, aluminium salts, AMPLIVAX®, AS15, BCG, CP-870,893, CpG7909, CyaA, dSLIM, flagellin or TLRS ligands derived from flagellin, FLT3 ligand, GM-CSF, IC30, IC31, Imiquimod (ALDARA®), resiquimod, ImuFact IMP321, Interleukins as IL-2, IL-13, IL-21, Interferon-alpha or -beta, or pegylated derivatives thereof, IS Patch, ISS, ISCOMATRIX, ISCOMs, JuvImmune®, LipoVac, MALP2, MF59, monophosphoryl lipid A, Montanide IMS 1312, Montanide ISA 206, Montanide ISA 50V, Montanide ISA-51, water-in-oil and oil-in-water emulsions, OK-432, OM-174, OM-197-MP-EC, ONTAK, OspA, PepTel® vector system, poly(lactid co-glycolid) [PLG]-based and dextran microparticles, talactoferrin SRL172, Virosomes and other Virus-like particles, YF-17D, VEGF trap, R848, beta-glucan, Pam3Cys, Aquila's QS21 stimulon, which is derived from saponin, mycobacterial extracts and synthetic bacterial cell wall mimics, and other proprietary adjuvants such as Ribi's Detox, Quil, or Superfos. Adjuvants such as Freund's or GM-CSF are preferred. Several immunological adjuvants (e.g., MF59) specific for dendritic cells and their preparation have been described previously (Allison and Krummel, 1995 The Yin and Yang of T cell costimulation.Science. 1995 Nov. 10; 270(5238):932-3. Review). Also cytokines may be used. Several cytokines have been directly linked to influencing dendritic cell migration to lymphoid tissues (e.g., TNF-), accelerating the maturation of dendritic cells into efficient antigen-presenting cells for T-lymphocytes (e.g., GM-CSF, IL-1 and IL-4) (U.S. Pat. No. 5,849,589, specifically incorporated herein by reference in its entirety) and acting as immunoadjuvants (e.g., IL-12, IL-15, IL-23, IL-7, IFN-alpha. IFN-beta) (Gabrilovich, 1996 Production of vascular endothelial growth factor by human tumors inhibits the functional maturation of dendritic cells Nat Med. 1996 October; 2(10):1096-103).
  • CpG immunostimulatory oligonucleotides have also been reported to enhance the effects of adjuvants in a vaccine setting. Without being bound by theory, CpG oligonucleotides act by activating the innate (non-adaptive) immune system via Toll-like receptors (TLR), mainly TLR9. CpG triggered TLR9 activation enhances antigen-specific humoral and cellular responses to a wide variety of antigens, including peptide or protein antigens, live or killed viruses, dendritic cell vaccines, autologous cellular vaccines and polysaccharide conjugates in both prophylactic and therapeutic vaccines. More importantly it enhances dendritic cell maturation and differentiation, resulting in enhanced activation of TH1 cells and strong cytotoxic T-lymphocyte (CTL) generation, even in the absence of CD4 T cell help. The TH1 bias induced by TLR9 stimulation is maintained even in the presence of vaccine adjuvants such as alum or incomplete Freund's adjuvant (IFA) that normally promote a TH2 bias. CpG oligonucleotides show even greater adjuvant activity when formulated or co-administered with other adjuvants or in formulations such as microparticles, nanoparticles, lipid emulsions or similar formulations, which are especially necessary for inducing a strong response when the antigen is relatively weak. They also accelerate the immune response and enable the antigen doses to be reduced by approximately two orders of magnitude, with comparable antibody responses to the full-dose vaccine without CpG in some experiments (Krieg, 2006). U.S. Pat. No. 6,406,705 B1 describes the combined use of CpG oligonucleotides, non-nucleic acid adjuvants and an antigen to induce an antigen-specific immune response. A CpG TLR9 antagonist is dSLIM (double Stem Loop Immunomodulator) by Mologen (Berlin, Germany) which is a preferred component of the pharmaceutical composition of the present invention. Other TLR binding molecules such as RNA binding TLR 7, TLR 8 and/or TLR 9 may also be used.
  • Other examples for useful adjuvants include, but are not limited to chemically modified CpGs (e.g. CpR, Idera), dsRNA analogues such as Poly(I:C) and derivates thereof (e.g. AmpliGen®, Hiltonal®, poly-(ICLC), poly(IC-R), poly(I:C12U), non-CpG bacterial DNA or RNA as well as immunoactive small molecules and antibodies such as cyclophosphamide, sunitinib, Bevacizumab®, celebrex, NCX-4016, sildenafil, tadalafil, vardenafil, sorafenib, temozolomide, temsirolimus, XL-999, CP-547632, pazopanib, VEGF Trap, ZD2171, AZD2171, anti-CTLA4, other antibodies targeting key structures of the immune system (e.g. anti-CD40, anti-TGFbeta, anti-TNFalpha receptor) and SC58175, which may act therapeutically and/or as an adjuvant. The amounts and concentrations of adjuvants and additives useful in the context of the present invention can readily be determined by the skilled artisan without undue experimentation.
  • Preferred adjuvants are imiquimod, resiquimod, GM-CSF, cyclophosphamide, sunitinib, bevacizumab, interferon-alpha, CpG oligonucleotides and derivates, poly-(I:C) and derivates, RNA, sildenafil, and particulate formulations with PLG or virosomes.

  • The present invention further includes a method for producing a personalized pharmaceutical for an individual patient comprising manufacturing a pharmaceutical composition comprising at least one peptide selected from a warehouse of pre-screened TUMAPs, wherein the at least one peptide used in the pharmaceutical composition is selected for suitability in the individual patient. Preferably, the pharmaceutical composition is a vaccine.The method could also be adapted to produce T cell clones for down-stream applications such as TCR isolations.
  • A “personalized pharmaceutical” shall mean specifically tailored therapies for one individual patient that will only be used for therapy in such individual patient, including actively personalized cancer vaccines and adoptive cellular therapies using autologous patient tissue.
  • As used herein, the term “warehouse” shall refer to a group of peptides that have been pre-screened for immunogenicity and over-presentation in a particular tumour type. The term “warehouse” is not intended to imply that the particular peptides included in the vaccine have been pre-manufactured and stored in a physical facility, although that possibility is contemplated. It is expressly contemplated that the peptides may be manufactured de novo for each individualized vaccine produced, or may be pre-manufactured and stored.
  • The warehouse (e.g. in the form of a database) is composed of tumour-associated peptides which were highly overexpressed in the tumour tissue of several HLA-A, HLA-B and HLA-C positive CLL patients analyzed (see tables above). It contains MHC class I and MHC class II peptides. In addition to the tumor associated peptides collected from several GBM tissues, the warehouse may contain an HLA-A*02 and an HLA-A*24 marker peptide. These peptides allow comparison of the magnitude of T-cell immunity induced by TUMAPS in a quantitative manner and hence allow important conclusion to be drawn on the capacity of the vaccine to elicit anti-tumor responses. Secondly, it functions as an important positive control peptide derived from a “non-self” antigen in the case that any vaccine-induced T-cell responses to TUMAPs derived from “self” antigens in a patient are not observed. And thirdly, it may allow conclusions to be drawn, regarding the status of immunocompetence of the patient population.
  • HLA class I and II TUMAPs for the warehouse are identified by using an integrated functional genomics approach combining gene expression analysis, mass spectrometry, and T-cell immunology. The approach assures that only TUMAPs truly present on a high percentage of tumours but not or only minimally expressed on normal tissue, are chosen for further analysis. For peptide selection, CLL samples from patients and blood from healthy donors were analyzed in a stepwise approach:
  • 1. HLA ligands from the malignant material were identified by mass spectrometry
  • 2. Genome-wide messenger ribonucleic acid (mRNA) expression analysis by microarrays was used to identify genes over-expressed in the malignant tissue (CLL) compared with a range of normal organs and tissues
  • 3. Identified HLA ligands were compared to gene expression data. Peptides encoded by selectively expressed or over-expressed genes as detected in step 2 were considered suitable TUMAP candidates for a multi-peptide vaccine.
  • 4. Literature research was performed in order to identify additional evidence supporting the relevance of the identified peptides as TUMAPs
  • 5. The relevance of over-expression at the mRNA level was confirmed by redetection of selected TUMAPs from step 3 on tumor tissue and lack of (or infrequent) detection on healthy tissues
  • 6. To assess whether an induction of in vivo T-cell responses by the selected peptides may be feasible, in vitro immunogenicity assays were performed using human T cells from healthy donors as well as from CLL patients.
  • In an aspect, the peptides are pre-screened for immunogenicity before being included in the warehouse. By way of example, and not limitation, the immunogenicity of the peptides included in the warehouse is determined by a method comprising in vitro T-cell priming through repeated stimulations of CD8+ T cells from healthy donors with artificial antigen presenting cells loaded with peptide/MHC complexes and anti-CD28 antibody.
  • This method is preferred for rare cancers and patients with a rare expression profile. In contrast to multi-peptide cocktails with a fixed composition as currently developed the warehouse allows a significantly higher matching of the actual expression of antigens in the tumour with the vaccine. Selected single or combinations of several “off-the-shelf” peptides will be used for each patient in a multitarget approach. In theory an approach based on selection of e.g. 5 different antigenic peptides from a library of 50 would already lead to approximately 17 million possible drug product (DP) compositions.
  • In an aspect, the peptides are selected for inclusion in the vaccine based on their suitability for the individual patient based on the method according to the present invention as described herein, and as follows.
  • The HLA phenotype, transcriptomic and peptidomic data will be gathered from the patient's tumour material and blood samples to identify the most suitable peptides for each patient containing warehouse and patient-unique (ie. mutated) TUMAPs. Those peptides will be chosen, which are selectively or over-expressed in the patients tumor and, where possible, showed strong in vitro immunogenicity if tested with the patients individual PBMCs.
  • Preferably, the peptides included in the vaccine are identified by a method comprising: (a) identifying tumour-associated peptides (TUMAPs) presented by a tumor sample from the individual patient; (b) comparing the peptides identified in (a) with a warehouse (database) of peptides as described above; and (c) selecting at least one peptide from the warehouse (database) that correlates with a tumour-associated peptide identified in the patient. For example, the TUMAPs presented by the tumor sample are identified by: (al) comparing expression data from the tumor sample to expression data from a sample of normal tissue corresponding to the tissue type of the tumor sample to identify proteins that are over-expressed or aberrantly expressed in the tumor sample; and (a2) correlating the expression data with sequences of MHC ligands bound to MHC class I and/or class II molecules in the tumor sample to identify MHC ligands derived from proteins over-expressed or aberrantly expressed by the tumor. Preferably, the sequences of MHC ligands are identified by eluting bound peptides from MHC molecules isolated from the tumor sample, and sequencing the eluted ligands. Preferably, the tumor sample and the normal tissue are obtained from the same patient.
  • In addition to, or as an alternative to, selecting peptides using a warehousing (database) model, TUMAPs may be identified in the patient de novo and then included in the vaccine. As one example, candidate TUMAPs may be identified in the patient by (a1) comparing expression data from the tumor sample to expression data from a sample of normal tissue corresponding to the tissue type of the tumor sample to identify proteins that are over-expressed or aberrantly expressed in the tumor sample; and (a2) correlating the expression data with sequences of MHC ligands bound to MHC class I and/or class II molecules in the tumor sample to identify MHC ligands derived from proteins over-expressed or aberrantly expressed by the tumor. As another example, proteins may be identified containing mutations that are unique to the tumor sample relative to normal corresponding tissue from the individual patient, and TUMAPs can be identified that specifically target the mutation. For example, the genome of the tumour and of corresponding normal tissue can be sequenced by whole genome sequencing: For discovery of non-synonymous mutations in the protein-coding regions of genes, genomic DNA and RNA are extracted from tumour tissues and normal non-mutated genomic germline DNA is extracted from peripheral blood mononuclear cells (PBMCs). The applied NGS approach is confined to the re-sequencing of protein coding regions (exome re-sequencing). For this purpose, exonic DNA from human samples is captured using vendor-supplied target enrichment kits, followed by sequencing with e.g. a HiSeq2000 (Illumina). Additionally, tumour mRNA is sequenced for direct quantification of gene expression and validation that mutated genes are expressed in the patients' tumours. The resultant millions of sequence reads are processed through software algorithms. The output list contains mutations and gene expression. Tumour-specific somatic mutations are determined by comparison with the PBMC-derived germline variations and prioritized.. The de novo identified peptides may then be tested for immunogenicity as described above for the warehouse, and candidate TUMAPs possessing suitable immunogenicity are selected for inclusion in the vaccine.
  • In one exemplary embodiment, the peptides included in the vaccine are identified by: (a) identifying tumour-associated peptides (TUMAPs) presented by a tumor sample from the individual patient by the methdos described above; (b) comparing the peptides identified in a) with a warehouse of peptides that have been prescreened for immunogenicity and overpresentation in tumors as compared to corresponding normal tissue; (c) selecting at least one peptide from the warehouse that correlates with a tumour-associated peptide identified in the patient; and (d) optionally, selecting at least one peptide identified de novo in (a) confirming its immunogenicity.
  • In one exemplary embodiment, the peptides included in the vaccine are identified by: (a) identifying tumour-associated peptides (TUMAPs) presented by a tumor sample from the individual patient; and (b) selecting at least one peptide identified de novo in (a) and confirming its immunogenicity.
  • Once the peptides are selected, the vaccine is manufactured.
  • The vaccine preferably is a liquid formulation consisting of the individual peptides dissolved in 33% DMSO.
  • Each peptide to be included into a product is dissolved in DMSO. The concentration of the single peptide solutions has to be chosen depending on the number of peptides to be included into the product. The single peptide-DMSO solutions are mixed in equal parts to achieve a solution containing all peptides to be included in the product with a concentration of -2.5 mg/ml per peptide. The mixed solution is then diluted 1:3 with water for injection to achieve a concentration of 0.826 mg/ml per peptide in 33% DMSO. The diluted solution is filtered through a 0.22 pm sterile filter. The final bulk solution is obtained.
  • Final bulk solution is filled into vials and stored at −20° C. until use. One vial contains 700 μL solution containing 0.578 mg of each peptide. Of this, 500 μL (approx. 400 μg per peptide) will be applied for intradermal injection.

    • EXAMPLES Example 1
  • Identification and Quantitation of Tumor Associated Peptides Presented on the Cell Surface
  • Tissue Samples
  • Patients' tumor samples were provided by University of Tübingen, Tübingen, Germany. Written informed consents of all patients had been given. For ligandome analysis, PBMC from CLL patients (>80% CLL cell frequency) as well as PBMC from healthy volunteers (HVs) were isolated by density gradient centrifugation. Informed consent was obtained in accordance with the Helsinki protocol. This study was performed according to the guidelines of the local ethics committee. HLA typing was carried out by the Department of Hematology and Oncology, Tübingen. Samples were stored at −80° C. until further use.
  • Quantification of HLA Surface Expression
  • For comparison with healthy autologous B lymphocytes, quantification of HLA surface expression was performed in patient samples containing at least 0.5% CD5−CD19+ normal B cells. HLA surface expression was analyzed using the QIFIKIT® quantitative flow cytometric assay (Dako) according to the manufacturer's instructions. In brief, triplicates of each sample were stained with the pan-HLA class I specific monoclonal antibody (mAb) W6/32, HLA-DR specific mAb L243 (both produced in house) or IgG isotype control (BioLegend), respectively. Surface marker staining was carried out with directly labeled CD3 (BD), CD5 (BD) and CD19 (BD) antibodies. 7-AAD (BioLegend) was added as viability marker immediately prior to flow cytometric analysis on a FACSCanto Analyzer (BD).
  • Isolation of HLA Peptides from Tissue Samples
  • HLA class I and II molecules were isolated employing standard immunoaffinity purification as described previously. In brief, snap-frozen cell pellets were lysed in 10 mM CHAPS/PBS (AppliChem, St. Louis, Mo., USA/Gibco, Carlsbad, Calif., USA) containing 1× protease inhibitor (Complete, Roche, Basel, Switzerland). HLA molecules were single-step purified using the pan-HLA class I specific mAb W6/32 and the pan-HLA class II specific mAb TU39 respectively, covalently linked to CNBr-activated sepharose (GE Healthcare, Chalfont St Giles, UK). HLA:peptide complexes were eluted by repeated addition of 0.2% trifluoroacetic acid (TFA, Merck, Whitehouse Station, N.J., USA). Elution fractions E1-E8 were pooled and free HLA ligands were isolated by ultrafiltration using centrifugal filter units (Amicon, Millipore, Billerica, Mass., USA). HLA ligands were extracted and desalted from the filtrate using ZipTip C18 pipette tips (Millipore). Extracted peptides were eluted in 35 μl of 80% acetonitrile (ACN, Merck)/0.2% TFA, centrifuged to complete dryness and resuspended in 25 μl of 1% ACN/0.05% TFA. Samples were stored at −20° C. until analysis by LC-MS/MS.
  • Analysis of HLA Ligands by LC-MS/MS
  • Peptide samples were separated by reversed-phase liquid chromatography (nanoUHPLC, UltiMate 3000 RSLCnano,ThermoFisher, Waltham, Mass., USA) and subsequently analyzed in an on-line coupled LTQ Orbitrap XL hybrid mass spectrometer (ThermoFisher). Samples were analyzed in 5 technical replicates. Sample volumes of 5 μl (sample shares of 20%) were injected onto a 75 μm×2 cm trapping column (Acclaim PepMap RSLC, ThermoFisher) at 4 μl/min for 5.75 min. Peptide separation was subsequently performed at 50° C. and a flow rate of 175 nl/min on a 50 μm×50 cm separation column (Acclaim PepMap RSLC, ThermoFisher) applying a gradient ranging from 2.4-32.0% of ACN over the course of 140 min. Eluting peptides were ionized by nanospray ionization and analyzed in the mass spectrometer implementing a top 5 CID (collision induced dissociation) method generating fragment spectra for the 5 most abundant precursor ions in the survey scans. Resolution was set to 60,000. For HLA class I ligands, the mass range was limited to 400-650 m/z with charge states 2 and 3 permitted for fragmentation. For HLA class II, a mass range of 300-1,500 m/z was analyzed with charge states allowed for fragmentation.
  • Database Search and Spectral Annotation
  • For data processing, the software Proteome Discoverer (v1.3, ThermoFisher) was used to integrate the search results of the Mascot search engine (Mascot 2.2.04, Matrix Science) against the human proteome as comprised in the Swiss-Prot database (release: Sep. 27, 2013; 20,279 reviewed protein sequences contained). The search combined data of technical replicates and was not restricted by enzymatic specificity. Precursor mass tolerance was set to 5 ppm, fragment mass tolerance to 0.5 Da. Oxidized methionine was allowed as a dynamic modification. False discovery rates (FDR) were determined by the Percolator algorithm based on processing against a decoy database consisting of the shuffled target database. FDR was set at a target value of q≤0.05 (5% FDR). Peptide-spectrum matches (PSMs) with q≤0.05 were filtered according to additional, orthogonal parameters, to ensure spectral quality and validity. Mascot scores were filtered to ≥20. For HLA class I, peptide lengths were limited to 8-12 amino acids (aa) of length. For HLA class II, peptides were limited to 12-25 aa length. Protein grouping was disabled, allowing for multiple annotations of peptides (e.g. conserved sequences mapping into multiple proteins). For quality control, yield thresholds of ≥300 unique HLA class I ligands and ≥100 unique HLA class II ligands per sample were applied. HLA annotation was performed using SYFPEITHI or an extended in-house database.
  • Longitudinal Analysis of CLL Patient Ligandomes Over the Course of Therapy
  • For label-free quantification (LFQ) of the relative HLA ligand abundances over the course of therapy, the injected peptide amounts of paired samples were normalized and LC-MS/MS analysis was performed in 5 technical replicates for each sample.
  • In brief, relative amounts of substance of paired samples were calculated from average precursor ion intensities determined in dose-finding mass spectrometry runs and adjusted accordingly by dilution. Relative quantification of HLA ligands was performed by calculating the area under the curve of the corresponding precursor extracted ion chromatograms (XIC) using Proteome Discoverer 1.3. The ratios of the mean areas of the individual peptides in the 5 LFQ-MS runs of each sample were calculated and two-tailed t-tests were performed using an in-house Matlab script (v8.2, Mathworks).
  • Peptide Synthesis
  • The automated peptide synthesizer EPS221 (Abimed) was used to synthesize peptides using the 9-fluorenylmethyl-oxycarbonyl/tert-butyl (Fmoc/tBu) strategy as described. Synthetic peptides were used for validation of LC-MS/MS identifications as well as for functional experiments.
  • Amplification of Peptide-Specific T Cells
  • PBMC from CLL patients and healthy volunteers were cultured in RPMI1640 medium (Gibco) supplemented with 10% pooled human serum (PHS, produced in-house), 100 mM β-mercaptoethanol (Roth, Karlsruhe, Germany) and 1% penicillin/streptomycin (GE). For CD8+ T cell stimulation, PBMC were thawed and pulsed with 1 μg/ml per peptide. Peptide-pulsed PBMC (5-6×106 cells/ml) were cultured at 37° C. and 5% CO2 for 12 days. On day 0 and day 1.5 ng/ml IL-4 (R&D Systems, Minneapolis, Minn., USA) and 5 ng/ml IL-7 (Promokine, Heidelberg, Germany) were added to the culture medium. On days 3, 5, 7 and 9, 2 ng/ml IL-2 (R&D Systems) were added to the culture medium. Peptide-stimulated PBMC were functionally characterized by ELISPOT assays on day 12 and by intracellular cytokine staining on day 13 respectively. For CD4+ T-cell stimulation, culture was performed as described for CD8+ T cells with 2 modifications: pulsing was carried out with 10 μg/ml of HLA class II peptide and no IL-4 and IL-7 was added.
  • IFN-γ ELISPOT Assay
  • IFN-γ ELISPOT assays were carried out as described previously (33). In brief, 96-well nitrocellulose plates (Millipore) were coated with 1 mg/ml IFN-γ mAb (Mabtech, Cincinnati, Ohio, USA) and incubated over night at 4 ° C. Plates were blocked with 10% PHS for 2 h at 37° C. 5×105 cells/well of pre-stimulated PBMC were pulsed with 1 μg/ml (HLA class I) or 2.5 μg/ml (HLA class II) peptide and incubated for 24-26 h. Readout was performed according to manufacturer's instructions. Spots were counted using an ImmunoSpot S5 analyzer (CTL, Shaker Heights, Ohio, USA). T cell responses were considered to be positive when >15 spots/well were counted and the mean spot count per well was at least 3-fold higher than the mean number of spots in the negative control wells (according to the cancer immunoguiding program (CIP) guidelines).
  • Intracellular IFN-γ and TNF-α Staining
  • The frequency and functionality of peptide-specific CD8+ T cells was analyzed by intracellular IFN-γ and TNF-α staining. PBMC were pulsed with 1 μg/ml of individual peptide and incubated in the presence of 10 μg/ml Brefeldin A (Sigma, St. Louis, Mo., USA) and 10 μg/ml GolgiStop (BD) for 6-8 h. Cells were labeled using Cytofix/Cytoperm (BD), CD8-PECy7 (Beckman Coulter, Fullerton, Calif., USA), CD4-APC (BD Bioscience), TNF-α-PE (Beckman Coulter) and IFN-γ-FITC (BD). Samples were analyzed on a FACS Canto II.
  • The frequency of peptide-specific CD8+ T cells was determined by staining with anti-CD8 and HLA:peptide-tetramer-PE
  • Results
  • Primary CLL Cells Display No Loss or Down-regulation of HLA Expression Compared to Autologous Normal B Cells
  • HLA loss or down-regulation in malignancies may pose a major limitation for T cell based immunotherapy. Therefore, as a first step, the inventors determined the HLA expression levels on CD19+CD5+CLL cells compared to autologous CD19+CD5−B lymphocytes. HLA surface levels were quantified by flow cytometry in a panel of 7 CLL patients. HLA surface expression levels revealed patient-individual heterogeneity with total HLA class I molecule counts ranging from ˜42,500-288,500 molecules/cell on CLL cells and ˜32,000-256,500 molecules/cell on normal B cells. Patient individual analysis of HLA surface expression in triplicates revealed small, albeit significant differences in expression levels (P<0.01) for 4/7 patients (FIG. 1a ). HLA-DR expression ranged from ˜29,000-100,500 on CLL cells and ˜19,500-79,500 on B cells. Minor differences in HLA-DR levels (P<0.01) were detected for 5/7 patients. Statistical analysis of mean HLA surface expression on CLL cells compared to normal B cells showed no significant differences in HLA class I and II expression (FIGS. 1 c, 1 d). Taken together, these data demonstrate high levels of HLA class I and II expression on CLL cells without evidence of HLA loss or down-regulation compared to normal B cells.
  • LC-MS/MS identifies a vast array of naturally presented HLA class I & II ligands Mapping the HLA class I ligandomes of 30 CLL patients, the inventors were able to identify a total of 18,844 different peptides representing 7,377 source proteins, attaining >95% of maximum attainable coverage (FIG. 7). The numbers of different peptides identified per patient ranged from 345-2,497 (mean 1,131). Overall, peptides restricted by more than 30 different HLA-A and -B alleles (covering >99% of the Caucasian population_ENREF_27) were identified in this study. In the HV cohort of 30 PBMC donors, a total of 17,322 unique peptides representing 7,180 different source proteins were identified (>90% coverage). The HLA allele distribution in the HV cohort covered 100% of HLA-A and >80% of HLA-B alleles in the CLL patient cohort.
  • Analysis of the HLA class II ligandomes was performed for 20 CLL patients. A total of 5,059 unique peptides representing 1,486 source proteins was identified. The HLA class II HV cohort of 13 PBMC donors yielded 2,046 different peptides representing 756 source proteins.
  • Comparative Profiling of HLA Class I Ligandomes Reveals a Multitude of CLL-Associated Antigens
  • In order to identify novel CLL-associated antigens, the inventors compared the HLA ligand source proteomes of the CLL and HV cohorts. Overlap analysis of HLA source proteins revealed 2,148 proteins (29.1% of the mapped CLL source proteome) to be exclusively represented in the HLA ligandome of CLL (FIG. 2a ). With the aim of designing a broadly applicable off-the-shelf peptide vaccine, the inventors subsequently prioritized the selection of potential targets according to the following criteria:
  • CLL-exclusivity was defined as paramount criterion, followed by ranking of antigens according to frequency of representation in CLL ligandomes (FIG. 2b ). Our platform highlighted 49 source proteins (0.7% of the CLL source proteome) represented by 225 different HLA ligands showing CLL-exclusive representation in ≥20% of CLL patients. Applying the same antigen ranking strategy to HV PBMC exclusive antigens, a set of 71 ligandome-derived benign tissue-associated antigens (LiBAAs) and the 298 corresponding ligands (LiBAPs) were identified for use as internal control in immunological assays.
  • Apart from broadly represented CLL-LiTAAs suited for the design of off-the-shelf vaccines, a second panel of 2,099 CLL-exclusive antigens with representation frequencies <20% was identified by our platform. These targets lend themselves as repositories for more individualized therapeutic approaches.
  • Detection of Naturally Presented HLA Class I Ligands Derived from Established CLL-Associated Antigens by LC-MS/MS
  • Alongside the identification of novel CLL-associated antigens, a secondary approach focused on the ranking of the few established CLL-antigens within the present dataset of naturally presented HLA ligands. The inventors were able to identify 28 different HLA ligands representing 8 described CLL-associated antigens. Of note, only Fibromodulin (FMOD324-333, RINEFSISSF, HLA-A*23 (SEQ ID NO: 526) showed CLL-exclusive representation, ranking at #437 of CLL-antigens in the present dataset, due to low frequency of representation in the CLL patient cohort. The remaining seven antigens showed representation, both on CLL and HV PBMC, thus failing to fulfill the paramount criterion of CLL-exclusivity. However, for CD19, CD20, RHAMM and PRAME, CLL-associated overrepresentation of varying degrees was detected (FIG. 2c ).
  • Comparative Ligandome Profiling Identifies LiTAAs Shared Among Different Disease Stages and Risk Strata
  • In order to assess the applicability of the novel targets across different stages of disease, the inventors performed subset-specific ligandome profiling comparing patients in disease stages Binet A (n=9), B (n=7) and C (n=14). Overlap analysis of the 2,148 CLL-exclusive source proteins found 550 (25.6%) of them shared among at least two stages, with a core group of 137 proteins (6.1%) represented in patients of all three stages of disease (FIG. 2d ). Of note, 45/49 (91.8%) of LiTAAs belong to the core group of shared source proteins represented in all three subsets. Heatmap analysis of the representation frequencies of all 49 LiTAAs across Binet stages A, B and C is shown in FIG. 2 e.
  • Another focus was placed on determining the representation of LiTAAs in the subsets of high-risk patients carrying the 17p13 deletion (deli 7p, n=5) as compared to patients without this genetic aberration (no del17p, n=25). The inventors found 77.7% of the identified LiTAAs to be represented in both subsets (FIG. 2f ). Together, these data support the devised strategy of cohort-comprising analysis of HLA ligandomes for selection of broadly applicable targets.
  • Functional Characterization of HLA Class I LiTAPs Reveals CLL-Associated Immunoreactivity
  • In order to evaluate the immunogenicity and specificity of our HLA class I LiTAPs, the inventors next performed 12-day recall IFNy ELISPOT assays. A panel of 15 LiTAPs (6 A*02, 4 A*03 and 5 B*07 LiTAPs) was implemented for stimulation of HLA-matched PBMC obtained from CLL patients and healthy volunteers (FIG. 3a ). The inventors observed IFNy secretion for 14/15 (93.3%) of tested LiTAPs in CLL patients (3/4 A*03 (FIGS. 3c ), 6/6 A*02 and 5/5 B*07 LiTAPs (FIGS. 8c, 8f )), but not in healthy controls (0/10, FIG. 3b , FIGS. 8b, 8e ). These findings were confirmed exemplarily for PA*033 (DMXL11271-1279 SSSGLHPPK (SEQ ID NO:77)) by tetramer staining of CD8+ T cells and intracellular cytokine staining for IFNγ and TNFα (FIGS. 9a, 9b ). ELISPOT assays using HLA-matched benign tissue-derived LiBAPs were performed to control for the CLL-specificity of the observed LiTAP-directed immune recognition in CLL patients. The inventors tested a panel of 9 LiBAPs (3 A*02, 3 A* 03, 3*B*07) and observed no significant IFNγ secretion in any of the tested CLL patients (0/7 A*03 (FIG. 3d ), 0/10 A*02+ and 0/5 B*07 (FIGS. 8a, 8d )).
  • For the 14/15 LiTAPs showing immune recognition in 1 or more patients, the inventors calculated the allele-adjusted frequencies of HLA restricted presentation (as detected by LC-MS/MS) and the frequencies of immunoreactivity (as detected by ELISPOT) in CLL patients. Strikingly, a linear correlation of these two parameters was observed (Pearson's r=0.77, R2=0.59, FIG. 3e ). These findings suggest two main points: First, tumor-exclusive representation is prerequisite for immune recognition. Secondly, frequency of immune recognition can be directly deduced from the frequency of HLA restricted presentation for immunoreactive LiTAPs. Together, these data demonstrate the efficacy of our approach identifying immunologically relevant targets for CLL-specific peptide vaccines.
  • HLA Class II Ligandome Analysis Identifies Additional CD4+ T Cell Epitopes for Synergistic Vaccine Design
  • Because of the important indirect and direct roles CD4+ T cells play in anti-cancer immune responses, optimal vaccine design calls for the inclusion of additional HLA class II epitopes. The inventors performed overlap analysis of CLL and HV PBMC ligandomes and identified 937 proteins (63.0% of the identified CLL source proteins) to be exclusively represented in the ligandomes of CLL patients (FIG. 4a ). Applying the same antigen-ranking strategy as described for HLA class I, the inventors identified 73 HLA class II LiTAAs represented by 460 corresponding LiTAPs (FIG. 4b ). Functional characterization of a panel of 7 HLA class II LiTAPs (FIG. 4c ) in IFNy ELISPOT assays revealed significant IFNy secretion for 6/7 (85.7%) LiTAPs in CLL patients (FIG. 4e ), but not in healthy controls (0/10, FIG. 4d ). Next, the inventors performed combined analysis of HLA class I and II ligandomes in order to identify shared, synergistic targets. Overlap analysis of CLL-exclusive source proteins revealed 132 proteins to be represented both in HLA class I and II ligandomes (FIG. 4f ). Heatmap analysis identified 2 proteins displaying representation frequencies ≥20% in both ligandomes (B4GALT1 (26.7% class I/30.0% class II), HLA-DMA (20.0% class I/20% class II), FIG. 4g ). Strikingly, one of the class I LiTAPs (HLA-DMA206-214, HEIDRYTAI, B*18 (SEQ ID NO: 178)) was revealed to be completely embedded in the corresponding HLA class II LiTAP (VTHEIDRYTAIAY (SEQ ID No. 924)). Together, the inventors identified a panel of class II LiTAPs, which could be verified as T cell epitopes, as well as an array of potentially synergistic HLA class II ligands covering class I LiTAAs.
  • Longitudinal Analysis of CLL Patient Ligandomes Under Different Therapeutic Regimens
  • The scope of peptide based immunotherapy is maintenance therapy and eradication of MRD. As a consequence, peptide vaccination in CLL would take place after standard chemo-/immunotherapy. Therefore, the inventors analyzed HLA expression and performed ligandome profiling across different time points of CLL patients undergoing different therapeutic regimens.
  • The inventors quantified HLA class I and II surface expression in 4 patients undergoing rituximab treatment (Rt0 h, Rt24 h) and 1 patient receiving alemtuzumab (At0 h, At72 h, At7 d, FIGS. 10a-10d ). HLA surface expression showed patient-individual heterogeneity with no significant changes in mean HLA class I (Rt0 h=50,500, Rt24 h=48,000; At0 h=42,500, At7 d=61,500) and HLA class II (Rt0 h=36,500, Rt24 h=27,500; At0 h=47,000, At7 d=55,500) expression over the course of either therapeutic regimen.
  • Longitudinal HLA class I ligandome profiling was performed in single patients undergoing rituximab-bendamustin, alemtuzumab or ofatumumab treatment, respectively (FIGS. 5a-5c ). Differential presentation (≥2-fold change, p≤05) was observed for 11.1% of HLA class I ligands under rituximab-bendamustin treatment, for 21.6% of ligands under ofatumumab treatment and for 33.6% of ligands under alemtuzumab treatment. Overall, LiTAPs representing 8/49 (16.3%) LiTAAs were revealed to be differentially presented over the course of therapy. Taken together, these data demonstrate stable expression of surface HLA and robust presentation of LiTAPs over the course of different therapies.
  • Immune Responses Against LiTAPs Might be Associated with Improved Overall Survival of CLL Patients
  • As a last step, the inventors performed retrospective survival analysis of 33 CLL patients (FIG. 6a ) analyzed by ELISPOT assays comparing cases with 0-1 LiTAP-specific (n=23) versus >1 LiTAP-specific (n=10) T cell responses (FIG. 6b ). In the low-responding cohort 6/23 (26.1%) of patients, in the high-responding cohort 0/11 of patients died. Overall survival seems to be prolonged in the cohort showing >1 immune reactions.
    • Example 2
  • Synthesis of Peptides
  • All peptides were synthesized using standard and well-established solid phase peptide synthesis using the Fmoc-strategy. After purification by preparative RP-HPLC, ion-exchange procedure was performed to incorporate physiological compatible counter ions (for example trifluoro-acetate, acetate, ammonium or chloride).
  • Identity and purity of each individual peptide have been determined by mass spectrometry and analytical RP-HPLC. After ion-exchange procedure the peptides were obtained as white to off-white lyophilizates in purities of 90% to 99.7%.
  • All TUMAPs are preferably administered as trifluoro-acetate salts or acetate salts, other salt-forms are also possible. For the measurements of example 4, trifluoro-acetate salts of the peptides were used.
    • Example 3
  • MHC Binding Assays
  • Candidate peptides for T cell based therapies according to the present invention were further tested for their MHC binding capacity (affinity). The individual peptide-MHC complexes were produced by peptide-ligand exchange, where a cleavage-sensitive peptide is cleaved, and exchanged with the peptide of interest as analyzed. Only peptide candidates that can effectively bind and stabilize the peptide-receptive MHC molecules prevent dissociation of the MHC complexes. To determine the yield of the exchange reaction, an ELISA was performed based on the detection of the light chain (β2m) of stabilized MHC complexes. The assay was performed as generally described in Rodenko et al. (Rodenko et al., Nat Protoc. 1 (2006): 1120-1132).
  • 96 well MAXISorp plates (NUNC) were coated over night with 2 ug/ml streptavidin in PBS at room temperature, washed 4x and blocked for 1 h at 37° C. in 2% BSA containing blocking buffer. Refolded HLA-A*0201/MLA-001 monomers served as standards, covering the range of 15-500 ng/ml. Peptide-MHC monomers of the UV-exchange reaction were diluted 100 fold in blocking buffer. Samples were incubated for 1 h at 37° C., washed four times, incubated with 2 ug/ml HRP conjugated anti-β2m for 1 h at 37° C., washed again and detected with TMB solution that is stopped with NH2SO4. Absorption was measured at 450 nm. Candidate peptides that show a high exchange yield (preferably higher than 50%, most preferred higher than 75%) are generally preferred for a generation and production of antibodies or fragments thereof, and/or T cell receptors or fragments thereof, as they show sufficient avidity to the MHC molecules and prevent dissociation of the MHC complexes.

  • In Vitro Immunogenicity for MHC Class I Presented Peptides
  • In order to obtain information regarding the immunogenicity of the TUMAPs of the present invention, the inventors performed investigations using an in vitro T-cell priming assay based on repeated stimulations of CD8+ T cells with artificial antigen presenting cells (aAPCs) loaded with peptide/MHC complexes and anti-CD28 antibody. This way the inventors could show immunogenicity for HLA-A*0201 restricted TUMAPs of the invention, demonstrating that these peptides are T-cell epitopes against which CD8+ precursor T cells exist in humans.
  • In Vitro Priming of CD8+ T Cells
  • In order to perform in vitro stimulations by artificial antigen presenting cells loaded with peptide-MHC complex (pMHC) and anti-CD28 antibody, the inventors first isolated CD8+ T cells from fresh HLA-A*02 leukapheresis products via positive selection using CD8 microbeads (Miltenyi Biotec, Bergisch-Gladbach, Germany) of healthy donors obtained from the University clinics Mannheim, Germany, after informed consent.
  • PBMCs and isolated CD8+ lymphocytes were incubated in T-cell medium (TCM) until use consisting of RPMI-Glutamax (Invitrogen, Karlsruhe, Germany) supplemented with 10% heat inactivated human AB serum (PAN-Biotech, Aidenbach, Germany), 100 U/ml Penicillin/100 μg/ml Streptomycin (Cambrex, Cologne, Germany), 1 mM sodium pyruvate (CC Pro, Oberdorla, Germany), 20 μg/ml Gentamycin (Cambrex). 2.5 ng/ml IL-7 (PromoCell, Heidelberg, Germany) and 10 U/ml IL-2 (Novartis Pharma, Nürnberg, Germany) were also added to the TCM at this step.
  • Generation of pMHC/anti-CD28 coated beads, T-cell stimulations and readout was performed in a highly defined in vitro system using four different pMHC molecules per stimulation condition and 8 different pMHC molecules per readout condition.
  • The purified co-stimulatory mouse IgG2a anti human CD28 Ab 9.3 (Jung et al., Proc Natl Acad Sci USA 84 (1987): 4611-4615) was chemically biotinylated using Sulfo-N-hydroxysuccinimidobiotin as recommended by the manufacturer (Perbio, Bonn, Germany). Beads used were 5.6 μm diameter streptavidin coated polystyrene particles (Bangs Laboratories, Illinois, USA).
  • pMHC used for positive and negative control stimulations were A*0201/MLA-001 (peptide ELAGIGILTV (SEQ ID NO. 1017) from modified Melan-A/MART-1) and A*0201/DDX5-001 (YLLPAIVHI from DDX5, SEQ ID NO. 1018), respectively.
  • 800.000 beads/200 μI were coated in 96-well plates in the presence of 4×12.5 ng different biotin-pMHC, washed and 600 ng biotin anti-CD28 were added subsequently in a volume of 200 μl. Stimulations were initiated in 96-well plates by co-incubating 1×106 CD8+ T cells with 2×105 washed coated beads in 200 μl TCM supplemented with 5 ng/ml IL-12 (PromoCell) for 3 days at 37° C. Half of the medium was then exchanged by fresh TCM supplemented with 80 U/ml IL-2 and incubating was continued for 4 days at 37° C. This stimulation cycle was performed for a total of three times. For the pMHC multimer readout using 8 different pMHC molecules per condition, a two-dimensional combinatorial coding approach was used as previously described (Andersen et al., Nat. Protoc. 7 (2012): 891-902) with minor modifications encompassing coupling to 5 different fluorochromes. Finally, multimeric analyses were performed by staining the cells with Live/dead near IR dye (Invitrogen, Karlsruhe, Germany), CD8-FITC antibody clone SK1 (BD, Heidelberg, Germany) and fluorescent pMHC multimers. For analysis, a BD LSRII SORP cytometer equipped with appropriate lasers and filters was used. Peptide specific cells were calculated as percentage of total CD8+cells. Evaluation of multimeric analysis was done using the FlowJo software (Tree Star, Oreg., USA). In vitro priming of specific multimer+CD8+ lymphocytes was detected by by comparing to negative control stimulations. Immunogenicity for a given antigen was detected if at least one evaluable in vitro stimulated well of one healthy donor was found to contain a specific CD8+ T-cell line after in vitro stimulation (i.e. this well contained at least 1% of specific multimer+among CD8+ T-cells and the percentage of specific multimer+cells was at least 10× the median of the negative control stimulations).
  • In Vitro Immunogenicity for CLL Peptides
  • For tested HLA class I peptides, in vitro immunogenicity could be demonstrated by generation of peptide specific T-cell lines. As an exemplary result, peptide KFAEEFYSF (SEQ ID NO. 20) led to in vitro T-cell responses in 2 of 5 tested donors.
    • Example 5
  • Identification and Quantitation of Tumor Associated Peptides Presented on the Cell Surface
  • Tissue Samples:
  • In addition to the samples used for identification of peptides, an independent sample set comprising both normal and tumor (CLL) tissues was used for analysis/confirmation of HLA-A*02-associated peptides of the invention. Written informed consents of all patients had been given before surgery or autopsy. Tissues were shock-frozen immediately after excision and stored until isolation of TUMAPs at −70° C. or below.
  • Isolation of HLA Peptides from Tissue Samples
  • HLA peptide pools from shock-frozen tissue samples were obtained by immune precipitation from solid tissues according to a slightly modified protocol (Falk et al., Nature 351 (1991): 290-296; Seeger et al., Immunogenetics 49 (1999): 571-576) using the HLA-A*02-specific antibody BB7.2, the HLA-A, -B, C-specific antibody W6/32, CNBr-activated sepharose, acid treatment, and ultrafiltration.
  • Mass Spectrometry Analyses
  • The HLA peptide pools as obtained were separated according to their hydrophobicity by reversed-phase chromatography (nanoAcquity UPLC system, Waters) and the eluting peptides were analyzed in LTQ-velos and fusion hybrid mass spectrometers (ThermoElectron) equipped with an ESI source. Peptide pools were loaded directly onto the analytical fused-silica micro-capillary column (75 μm i.d.×250 mm) packed with 1.7 μm C18 reversed-phase material (Waters) applying a flow rate of 400 nL per minute. Subsequently, the peptides were separated using a two-step 180 minute-binary gradient from 10% to 33% B at a flow rate of 300 nL per minute. The gradient was composed of Solvent A (0.1% formic acid in water) and solvent B (0.1% formic acid in acetonitrile). A gold coated glass capillary (PicoTip, New Objective) was used for introduction into the nanoESl source. The LTQ-Orbitrap mass spectrometers were operated in the data-dependent mode using a TOP5 strategy. In brief, a scan cycle was initiated with a full scan of high mass accuracy in the orbitrap (R=30 000), which was followed by MS/MS scans also in the orbitrap (R=7500) on the 5 most abundant precursor ions with dynamic exclusion of previously selected ions. Tandem mass spectra were interpreted by SEQUEST and additional manual control. The identified peptide sequence was assured by comparison of the generated natural peptide fragmentation pattern with the fragmentation pattern of a synthetic sequence-identical reference peptide.
  • Label-free relative LC-MS quantitation was performed by ion counting i.e. by extraction and analysis of LC-MS features (Mueller et al., Proteomics. 7 (2007): 3470-3480). The method assumes that the peptide's LC-MS signal area correlates with its abundance in the sample. Extracted features were further processed by charge state deconvolution and retention time alignment (Mueller et al., J Proteome.Res 7 (2008): 51-61; Sturm et al., BMC. Bioinformatics. 9 (2008): 163). Finally, all LC-MS features were cross-referenced with the sequence identification results to combine quantitative data of different samples and tissues to peptide presentation profiles. The quantitative data were normalized in a two-tier fashion according to central tendency to account for variation within technical and biological replicates. Thus each identified peptide can be associated with quantitative data allowing relative quantification between samples and tissues. In addition, all quantitative data acquired for peptide candidates was inspected manually to assure data consistency and to verify the accuracy of the automated analysis. For each peptide a presentation profile was calculated showing the mean sample presentation as well as replicate variations. The profiles juxtapose CLL samples to a baseline of normal tissue samples. The presentation profile of an exemplary over-presented peptide is shown in FIG. 11.
