PRIORITY
[0001] This application claims the benefit of priority under 35 U.S.C. § 119(e) to U.S.
Provisional Application No. 62/516,667, filed June 7, 2017, the disclosure of which is incorporated herein by reference in its entirety.
BACKGROUND
[0002] One of the leading causes of death in the United States is cancer. The conventional methods of cancer treatment, like chemotherapy, surgery, or radiation therapy, tend to be either highly toxic or nonspecific to a cancer, or both, resulting in limited efficacy and harmful side effects. However, the immune system has the potential to be a powerful, specific tool in fighting cancers. In many cases tumors can specifically express genes whose products are required for inducing or maintaining the malignant state. These proteins may serve as antigen markers for the development and establishment of more specific anti-cancer immune response. The immune response may include the recruitment of immune cells that target tumors expressing these antigen markers. Additionally, the immune cells may express genes whose products are important to proper immune function and may serve as markers for specific types of immune cells. The boosting of this specific immune response has the potential to be a powerful anti-cancer treatment that can be more effective than conventional methods of cancer treatment and can have fewer side effects.

DETAILED DESCRIPTION
[0074] Additional aspects and advantages of the present disclosure will become apparent to those skilled in this art from the following detailed description, wherein illustrative aspects of the present disclosure are shown and described. As will be realized, the present disclosure is capable of other and different aspects, and its several details are capable of modifications in various respects, all without departing from the disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
[0075] As used herein, "potency" generally refers to measured bioactivity and may be quantified as an EC50 or IC50. Potency refers to the amount of a compound or conjugate needed to give an effect. For example, the potency of an immune- stimulatory compound which requires a lower amount of the immune- stimulatory compound compared with a different immune- stimulatory compound can be considered to have greater potency. Furthermore, the different immune- stimulatory compound requires a greater amount of the different immune- stimulatory compound to generate a response, and can therefore be considered lower potency. Potencies of bioactive compounds or conjugates may be measured over a concentration range and can be reported as those molar concentrations required to elicit or inhibit a percentage of the measured bioresponse. For example, a concentration required to stimulate 50% of observed maximal activity in the assay may be reported as an effective concentration 50 (EC50), to stimulate 90% activity as an EC90, or to stimulate 10% activity as an EC 10. For example, a concentration of an antagonist required to give 50% maximal inhibition of a biological activity may be reported as an inhibitory concentration 50 (IC50), to inhibit 90% as an IC90, or to inhibit 10% as an ICIO. This may allow for a comparison of the potencies of bioactive compounds on a molar basis by comparison of their EC or IC values for a given bioassay. For example, an immune- stimulatory conjugate or an immune- stimulatory compound with an EC50 or IC50 that is greater than 300 times the EC50 or IC50 of a control requires 300-fold higher, or more than 300-fold higher, concentration compared to the control to achieve a 50% bioresponse and has a potency weaker than the control by at least 300-fold. Therefore, an immune- stimulatory compound or conjugate that has an EC50 or IC50 not greater than about 300 times the EC50 or IC50 of a control compound may require no more than a 300-fold higher concentration than the control compound to achieve a 50% maximal bioresponse, no greater than 100 times the EC50 or IC50 requires no more than 100-fold higher concentration and no greater than 10 times the EC50 or IC50 requires no more than 10 times the concentration of the control. The potency of the immune- stimulatory compound or conjugate may be within 300-fold or better, 100-fold or better, or 10-fold or better the potency of the control.
[0076] As used herein, "control compound" refers to, in a case of an immune- stimulatory compound, the compound before attachment to a linker and antibody construct; in the case of an antibody construct, the construct before attachment of the linker and immune- stimulatory compound; or, in the case of a conjugate including an E3 ubiquitin ligase binding moiety, control compound refers to the immune- stimulatory compound attached to a linker that is attached to an E3 ubiquitin ligase binding moiety.
[0077] An "immune- stimulatory compound" as described herein, also referred to herein as an immune- stimulatory agent or molecule, refers to a molecule that stimulates the immune system by inducing activation or increasing activity of any of its components. For example, an immune stimulatory compound may bind directly to a component of the immune system and activate or increase an activity of the immune system or a component thereof. An immune stimulatory compound may also bind to an inhibitory component of the immune system and inactivate or decrease the activity of that component, thereby increasing an activity of the immune system. Immune- stimulatory compounds may have or cause antigenic specificity. In certain embodiments, an immune- stimulatory compound activates macrophages. In certain embodiments, an immune- stimulatory compound induces the secretion of cytokines by an antigen presenting cell. The increased activity or activation of the immune system may be evaluated using methods known in the field for evaluating an immune response (see, for example, J. Gratama, Cytometry A. 2008 Nov: 73(11): 971-4, the contents of which are incorporated herein in its entirety).
[0078] A "protein active site" as described herein, refers to a region of a protein target where a molecule (such as a substrate molecule or allosteric effector) binds to the target protein. The molecule may trigger a response upon binding to the the binding protein, e.g., inhibition of the activity of the binding protein or degradation of the binding protein. The protein active site includes the residues that interact with, e.g., bind covalently or non-covalently, a molecule such as an immune- stimulatory compound or a portion thereof. The protein active site may define a groove or pocket in the target protein wherein the interface between the groove or pocket and surrounding solvent is the solvent/active site interface of the protein active site.
[0079] The phrase "stimulate an immune response" refers to stimulating a response from immune cells that increases the activity or responsiveness of the immune system or a part thereof, such as, for example, inducing secretion of cytokines and/or chemokines, activating immune cells, e.g., T cells, B cells, macrophages, dendritic cells, etc., enhancing antigen presenting cell presentation of antigen, inducing antibody-dependent cell-mediated phagocytosis (ADCP), inducing antibody-dependent cell-mediated cytotoxicity (ADCC), NK cell or CD8+ T cell cytolytic activity, and/or blocking immune suppression.
[0080] As used herein, "homologous" or "homology" refer to the similarity or identity between a DNA, RNA, nucleotide, amino acid, or protein sequence to another DNA, RNA, nucleotide, amino acid, or protein sequence, respectively. Homology can be expressed in terms of a percentage of sequence identity of a first sequence to a second sequence. Percent (%) sequence identity with respect to a reference DNA sequence is the percentage of DNA nucleotides in a candidate sequence that are identical with the DNA nucleotides in the reference DNA sequence after aligning the sequences and introducing gaps, as necessary. Percent (%) sequence identity with respect to a reference amino acid sequence is the percentage of amino acid residues in a candidate sequence that are identical with the amino acid residues in the reference amino acid sequence after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity.

It will be understood that "substitution" or "substituted with" includes the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, i.e., a compound which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, etc. In certain embodiments, substituted refers to moieties having substituents replacing two hydrogen atoms on the same carbon atom, such as substituting the two hydrogen atoms on a single carbon with an oxo, imino or thioxo group. As used herein, the term "substituted" is contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and non-aromatic substituents of organic compounds. The permissible substituents can be one or more and the same or different for appropriate organic compounds.

[0105] In certain embodiments, the compounds disclosed herein have some or all of the 1H atoms replaced with H atoms. The methods of synthesis for deuterium-containing compounds are known in the art and include, by way of non-limiting example only, the following synthetic methods.
[0106] Deuterium substituted compounds are synthesized using various methods such as described in: Dean, Dennis C; Editor. Recent Advances in the Synthesis and Applications of Radiolabeled Compounds for Drug Discovery and Development. [In: Curr., Pharm. Des., 2000; 6(10)] 2000, 110 pp; George W.; Varma, Rajender S. The Synthesis of Radiolabeled Compounds via Organometallic Intermediates, Tetrahedron, 1989, 45(21), 6601-21; and Evans, E. Anthony. Synthesis of radiolabeled compounds, J. Radioanal. Chem., 1981, 64(1-2), 9-32.
[0107] Deuterated starting materials are readily available and are subjected to the synthetic methods described herein or otherwise known to provide for the synthesis of deuterium- containing compounds. Large numbers of deuterium-containing reagents and building blocks are available commercially from chemical vendors, such as Aldrich Chemical Co.
[0108] Compounds also include crystalline and amorphous forms of those compounds, pharmaceutically acceptable salts, and active metabolites of these compounds having the same type of activity, including, for example, polymorphs, pseudopolymorphs, solvates, hydrates, unsolvated polymorphs (including anhydrates), conformational polymorphs, and amorphous forms of the compounds, as well as mixtures thereof.
[0109] The phrases "parenteral administration" and "administered parenterally" as used herein means modes of administration other than enteral and topical administration, usually by injection, and includes, without limitation, intravenous, intramuscular, intraarterial, intrathecal,
intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal and intrasternal injection and infusion.
[0110] The phrase "pharmaceutically acceptable" is employed herein to refer to those
compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.
[0111] The phrase "pharmaceutically acceptable excipient" or "pharmaceutically acceptable carrier" as used herein means a pharmaceutically acceptable material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material. Each carrier must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not injurious to the patient. Some examples of materials which can serve as pharmaceutically acceptable carriers include: (1) sugars, such as lactose, glucose and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen- free water; (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer solutions; and (21) other non-toxic compatible substances employed in pharmaceutical formulations.
[0112] As used herein, "attached" refers to a covalent bond, between two or more groups.
Alternatively, attached may refer to the connection of two or more groups via a linker, e.g., a linker connecting a second binding domain to an antibody construct. A fusion may refer to a nucleic acid sequence of two separate domains being expressed in frame. For example, a binding domain can be attached as a fusion or by attachment (e.g., conjugation) via a linker to an antibody construct or other portion of a conjugate. For example, an antibody can be fused with an additional binding domain to create an antibody construct containing a fusion of the antibody and the additional binding domain. The antibody construct can be the result of the nucleic acid sequence of the binding domain being expressed in frame with the nucleic acid sequence of the antibody construct. The fusion can be the result of an in- frame nucleotide sequence encoding the antibody construct with the binding domain. As another example, an additional binding domain can be attached to an antibody construct via a linker, wherein the linker is attached (i.e., conjugated) to the binding domain and the linker is attached to the antibody construct. The binding domain can be linked to the linker by a chemical conjugation and the antibody construct can be linked to the linker by a chemical conjugation. The additional binding domain can be a second binding domain and/or a third binding domain as described herein. Furthermore, a binding domain can be a first binding domain attached to an Fc domain to produce the antibody construct as described herein, which may produce the first binding domain as a fusion with the Fc domain or a conjugate wherein the first binding domain can be linked to a linker and the linker can be linked to the Fc domain.

Tumor and Immune Cell Antigens
[0132] In cancer, there are several general groups of tumor antigens, including but not limited to: (i) viral tumor antigens which can be identical for any viral tumor of this type, (ii) carcinogenic tumor antigens which can be specific for patients and for the tumors, (iii) isoantigens of the transplantation type or tumor- specific transplantation antigens which can be different in all individual types of tumor but can be the same in different tumors caused by the same inciting biological event; and (iv) embryonic antigens.

[0135] Cluster of Differentiation 40 (CD40) is a member of the Tumor Necrosis Factor Receptor (TNF-R) family. CD40 can be a 50 kDa cell surface glycoprotein that can be constitutively expressed in normal cells, such as monocytes, macrophages, B lymphocytes, dendritic cells, endothelial cells, smooth muscle cells, fibroblasts and epithelium, and in tumor cells, including B-cell lymphomas and many types of solid tumors. Expression of CD40 can be increased in antigen presenting cells in response to IL-Ιβρ, IFN-γ, GM-CSF, and LPS induced signaling events.
[0136] Examples of agonistic CD40 monoclonal antibodies include CP-870,893, dacetuzumab, Chi Lob 7/4, SEA-CD40, ADC- 1013, 3C3, or 3G5.
[0137] Cluster of Differentiation 205 (CD205 or DEC-205) is a member of the C-type multilectin family of endocytic receptors, which can include the macrophage mannose receptor (MMR) and the phospholipase A2 receptor (PLA2R). DEC-205 can be a 205 kDa endocytic receptor highly expressed in cortical thymic epithelial cells, thymic medullary dendritic cells (CDl lc+ CD8+), subpopulations of peripheral dendritic cells (CDl lc+ CD8+). The DEC-205+ CDl lc+ CD8+ dendritic cells (DCs) can function in cross-presentation of antigens derived from apoptotic cells. Additionally, DEC-205 can be significantly upregulated during DC maturation. DEC-205 can also be expressed at moderate levels in B cells and low levels in macrophages and T cells.
[0138] After antigen binding to DEC-205, the receptor- antigen complex can be internalized whereupon the antigen can be processed and be presented on the DC surface by a major histocompatibility complex class II (MHC II) or MHC class I. DEC-205 can deliver antigen to DCs for antigen presentation on MHC class II and cross-presentation on MHC class I. DEC-205 mediated antigen delivery for antigen presentation in DCs without an inflammatory stimulus can result in tolerance. Conversely, DEC-205 mediated antigen delivery in DCs in the presence of a maturational stimulus (e.g., a CD40 agonist) can result in long-term immunity via activation of antigen- specific CD4+ and CD8+ T cells.
[0139] CD36 mannose scavenger receptor 1 is an oxidized LDL receptor with two
transmembrane domains located in the caveolae of the plasma membrane. It can be classified as a Class B scavenger receptor, which can be characterized by involvement in the removal of foreign substances and waste materials. This receptor can also be involved in cell adhesion, phagocytosis of apoptotic cells, and metabolism of long-chain fatty acids.
[0140] TNFR2 (tumor necrosis factor receptor 2), also known as TNFRSF1B (tumor necrosis factor receptor super family IB) and CD 120b, is a single-pass type I membrane protein and the member of TNFR superfamily containing 4 cysteine-rich domains (CRD) repeats. In addition to the full length membrane- anchored form, soluble TNFR2 can be generated via two distinct mechanisms: (1) shedding via proteolytic processing of the full membrane anchored from, and (2) translation from an alternatively spliced message encoding the extracellular domains of TNFR2. TNFR2 is the receptor with high affinity for TNF-alpha and approximately 5-fold lower affinity for homotrimeric lymphotoxin-alpha. TNFR2 (Tumor Necrosis Factor Receptor Type II) and TNF-receptor 1 form a heterocomplex that mediates the recruitment of two anti- apoptotic proteins, c-IAPl and C-IAP2, which possess E3 ubiquitin ligase activity. c-IAPl can potentiate TNF- induced apoptosis by the ubiquitination and degradation of TNF-receptor-associated factor 2, which mediates anti- apoptotic signals. Knockout studies in mice suggest a role of TNFR2 in protecting neurons from apoptosis by stimulating antioxidative pathways.

[0159] The HER2/neu (human epidermal growth factor receptor 2/receptor tyro sine-protein kinase erbB-2) is part of the human epidermal growth factor family. Overexpression of this protein can be shown to play an important role in the progression of cancer, for example, breast cancer. The HER2/neu protein can function as a receptor tyrosine kinase and autophosphorylates upon dimerization with binding partners. HER2/neu can activate several signaling pathways including, for example, mitogen-activated protein kinase, phosphoinositide 3-kinase,
phospholipase Cy, protein kinase C, and signal transducer and activator of transcription (STAT). Examples of antibodies that can target and inhibit HER2/neu can include trastuzumab and pertuzumab.
[0160] EGFR (epidermal growth factor receptor) encodes a member of the human epidermal growth factor family. Mutations that can lead to EGFR overexpression or over activity can be associated with a number of cancers, including squamous cell carcinoma and glioblastomas. EGFR can function as a receptor tyrosine kinase and ligand binding can trigger dimerization with binding partners and autophosphorylation. The phosphorylated EGFR can then activate several downstream signaling pathways including mitogen-activated protein kinase, phosphoinositide 3- kinase, phospholipase Cy, protein kinase C, and signal transducer and activator of transcription (STAT). Examples of antibodies that can target and inhibit EGFR can include cetuximab, panutumumab, nimotuzumab, and zalutumumab. One mutant variant of EGFR is EGFRvIII (epidermal growth factor receptor variant III, also referred to as de2-7EGFR). EGFRvIII is the result of an EGFR gene rearrangement in which exons 2-7 of the extracellular domain are deleted. This mutation can result in a mutant receptor incapable of binding to any known ligand. The resulting receptor can engage in a constitutive low-level signaling and can be implicated in tumor progression. Examples of antibodies that can target EGFRvIII can include AMG595 and ABT806.

HER3 can play an active role in cell proliferation and survival, and can be overexpressed, overactive, and/or mutated in various cancers. For example, HER3 can be overexpressed in breast, ovarian, prostate, colon, pancreas, stomach, oral, and lung cancers. The antibody patritumab can target and inhibit HER3.

An antigen binding domain can be in a scaffold, in which a scaffold is a supporting framework for the antigen binding domain. An antigen binding domain can be in a non-antibody scaffold. An antigen binding domain can be in an antibody scaffold. An antibody construct can comprise an antigen binding domain in a scaffold. The antibody construct can further comprise an Fc fusion protein product. In some embodiments, the antibody construct is an Fc fusion protein.
[0188] In some embodiments, an antibody construct can comprise an antigen binding domain that can specifically bind to a tumor antigen. A tumor antigen, also referred to as a tumor associated antigen, is an antigen that can be expressed by a cancer cell, a neoplastic tumor cell and/or within a tumor microenvironment. It is preferably not expressed or expressed at low levels on normal (non-cancerous) cells. For example, a tumor antigen can be an antigen expressed on a cell associated within a tumor, such as a neoplastic cell, or a tumor associated cell such as a stromal cell, endothelial cell, fibroblast, or tumor- infiltrating immune cell. For example, the tumor antigen Her2/Neu can be overexpressed by certain types of breast and ovarian cancer. A tumor antigen can also be ectopically expressed by a tumor and contribute to deregulation of the cell cycle, reduced apoptosis, metastasis, or escape from immune surveillance. Tumor antigens can generally be proteins or polypeptides derived therefrom, but also can be glycans, lipids, or other small organic molecules. Additionally, a tumor antigen can arise through increases or decreases in post-translational processing exhibited by a cancer cell compared to a normal cell, for example, protein glycosylation, protein lipidation, protein phosphorylation, or protein acetylation.

[0191] In certain embodiments, a binding domain specifically binds to an antigen selected from the group consisting of comprising Her2/Neu (CD340), EGFR, CMET, HER3, MUCl, MUCl 6,
EPCAM, MSLN, CA6, NAPI2B, TROP2, CEA, CLDN18.2, EGFRvIII, FAP, EphA2, RON,
LY6E, FRA, PSMA, DLL3, PTK7, LIV1, ROR1, MAGE- A3, and NY-ESO-1.
[0192] A binding domain of an antibody construct can be selected from any domain that specifically binds to an antigen, including but not limited to, from a monoclonal antibody, a polyclonal antibody, a recombinant antibody, or a functional fragment thereof, for example, a heavy chain variable domain (VH) and a light chain variable domain (VL), or from a non-antibody such as a DARPin, an affimer, an avimer, a knottin, a monobody, an affinity clamp, an ectodomain, a receptor ectodomain, a receptor, a cytokine, a ligand, an immunocytokine, a T-cell receptor, a VNAR, an anticalin, or a recombinant T-cell receptor. In some embodiments, a binding domain of an antibody construct is from a monoclonal antibody, a polyclonal antibody, a recombinant antibody, or a functional fragment thereof, for example, a heavy chain variable domain (VH) and a light chain variable domain (VL).
[0193] The antigen binding domain of an antibody construct can be at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% homologous to an antigen binding domain selected from, but not limited to, a monoclonal antibody, a polyclonal antibody, a recombinant antibody, or a functional fragment thereof, for example, a heavy chain variable domain (VH) and a light chain variable domain (VL), or from a non-antibody, such as a DARPin, an affimer, an avimer, a knottin, a monobody, an affinity clamp, an ectodomain, a receptor ectodomain, a receptor, a cytokine, a ligand, an immunocytokine, a T-cell receptor, a VNAR, an anticalin, or a
recombinant T-cell receptor.
[0194] A binding domain, for example an antigen binding domain from a monoclonal antibody, can comprise a light chain and a heavy chain. In one aspect, the monoclonal antibody binds to an antigen present on the surface of an antigen presenting cell (APC antigen) and comprises the light chain of an anti-APC antigen antibody and the heavy chain of an anti-APC antigen antibody, which bind an APC antigen. In another aspect, the monoclonal antibody binds to a tumor antigen comprises the light chain of a tumor antigen (anti-tumor) antibody and the heavy chain of a tumor antigen (anti-tumor) antibody, which bind to the tumor antigen.
[0195] An antibody construct can be an antibody. An antibody molecule can include of two identical light protein chains (light chains) and two identical heavy protein chains (heavy chains), all held together covalently by interchain disulfide linkages. Structurally, various functions of an antibody can be confined to discrete protein regions or domains. The sites that can recognize and can bind to antigen consist of three complementarity determining regions (CDRs; also referred to as hyper- variable regions) that lie within the variable heavy chain regions and within the variable light chain regions at the N-terminal ends of the two heavy and two light chains. The constant domains can provide the general framework of the antibody and may not be involved directly in binding the antibody to an antigen, but can be involved in various effector functions, such as participation of the antibody in antibody-dependent cellular cytotoxicity (ADCC).
[0196] The variable domains of natural light and heavy chains can have the same general structures, and each domain can comprise four framework regions, whose sequences can be somewhat conserved, connected by three CDRs. The four framework regions can largely adopt a β-sheet conformation and the CDRs can form loops connecting, and in some aspects forming part of, the β -sheet structure. The CDRs in each chain can be held in close proximity by the framework regions and, with the CDRs from the other chain, can contribute to the formation of the antigen binding site.
[0197] An antibody can include an antibody of any type, which can be assigned to different classes of immunoglobins, e.g., IgA, IgD, IgE, IgG, and IgM. Several different classes can be further divided into isotypes, e.g., IgGl, IgG2, IgG3, IgG4, IgAl, and IgA2. Exemplary heavy chain sequences of reference antibodies can be used to identify residue variants and mutants.
[0198] An exemplary heavy chain sequence for human IgGl heavy chain is that of the human IgGl antibody, and can comprise:

[0200] An exemplary heavy chain reference sequence for human IgG4 heavy chain can comprise:

[0201] The heavy-chain constant regions (Fc) that corresponds to the different classes of immunoglobulins can be α, δ, ε, γ, and μ. The light chains can be one of either kappa or κ and lambda or λ, based on the amino acid sequences of the constant domains. The Fc region can contain an Fc domain. An Fc receptor can bind an Fc domain. An Fc domain can comprise amino acid residues 216 to 447 of an IgGl, which are part of SEQ ID NO: 898. An Fc domain can comprise amino acid residues 216 to 442 of an IgG2, which are part of SEQ ID NO: 899. An Fc domain can comprise amino acid residues 216 to 444 of an IgG4, which are part of SEQ ID NO: 900. Antibody constructs can also include any fragment or recombinant forms thereof (e.g., scFVs and domain antibodies). Antibody constructs can also include any fragment or
recombinant forms thereof (e.g., scFVs and domain antibodies) of non-antibody scaffolds, including but not limited to anti-calins, affibodies, affilins, atrimers, avimers, bicyclic peptides, centyrins, Cys-knots, Darpins, fibronections, Kunitz domains, O-bodies, or peptibodies.
[0202] An antibody construct can comprise an antigen binding domain of an antibody. An antigen binding domain of an antibody can comprise one or more light chain CDRs (LCDRs) and one or more heavy chain CDRs (HCDRs), or one or more LCDRs or one or more HCDRs. For example, an antibody binding domain of an antibody construct can comprise one or more of the following: a light chain complementary determining region 1 (LCDR1), a light chain
complementary determining region 2 (LCDR2), or a light chain complementary determining region 3 (LCDR3). For another example, an antibody binding domain can comprise one or more of the following: a heavy chain complementary determining region 1 (HCDR1), a heavy chain complementary determining region 2 (HCDR2), or a heavy chain complementary determining region 3 (HCDR3). In some embodiments, an antigen binding domain comprises LCDR1, LCDR2, LCDR3, HCDR1, HCDR2 and HCDR3. Unless stated otherwise, the CDRs described herein can be defined according to the IMGT (the international ImMunoGeneTics information system).
[0203] An antigen binding domain can comprise only the heavy chain of an antibody. An antigen binding domain can comprise only the variable domain of the heavy chain of an antibody.
Alternatively, an antigen binding domain can comprise only the light chain of an antibody. An antigen binding domain can comprise only the variable light chain of an antibody.
[0204] An antibody construct can comprise an antibody fragment. An antibody fragment can include (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CHI domains; (ii) a F(ab')2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; and (iii) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody. Although the two domains of the Fv fragment, VL and VH, can be coded for by separate genes, they can be linked by a synthetic linker to be made as a single protein chain in which the VL and VH regions pair to form monovalent molecules. F(ab')2 and Fab' moieties can be produced recombinantly. [0205] An Fv can be the minimum antibody fragment which contains a complete antigen- recognition and antigen-binding site. This region can consist of a dimer of one heavy chain and one light chain variable domain in tight, non-covalent association. In this configuration the three hypervariable regions of each variable domain can interact to define an antigen-binding site on the surface of the VH-VL dimer. A single variable domain (or half of an Fv comprising only CDRs specific for an antigen) can recognize and bind antigen, although at a lower affinity than the entire binding site.
[0206] An antibody used herein can be chimeric or "humanized." Chimeric and humanized forms of non-human (e.g., murine) antibodies can be chimeric immunoglobulins,
immunoglobulin chains or fragments thereof (such as Fv, Fab, Fab', F(ab')2 or other target- binding subdomains of antibodies), which can contain minimal sequences derived from non- human immunoglobulin. In general, the humanized antibody can 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 frame work regions (FR) are those of a human immunoglobulin sequence. The humanized antibody can also comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin consensus sequence.
[0207] An antibody described herein can be a human antibody. As used herein, "human antibodies" can include antibodies having, for example, the amino acid sequence of a human immunoglobulin and include antibodies isolated from human immunoglobulin libraries or from animals transgenic for one or more human immunoglobulins that do not express endogenous immunoglobulins. Human antibodies can be produced using transgenic mice which are incapable of expressing functional endogenous immunoglobulins, but which can express human immunoglobulin genes. Completely human antibodies that recognize a selected epitope can be generated using guided selection. In this approach, a selected non-human monoclonal antibody, e.g., a mouse antibody, is used to guide the selection of a completely human antibody recognizing the same epitope
[0208] An antibody described herein can be a bispecific antibody or a dual variable domain antibody (DVD). Bispecific and DVD antibodies are monoclonal, often human or humanized, antibodies that have binding specificities for at least two different antigens.
[0209] An antibody described herein can be a derivatized antibody. For example, derivatized antibodies can be modified by glycosylation, deglycosylation, defucosylation, acetylation, pegylation, phosphorylation, amidation, derivatization by known protecting/blocking groups, proteolytic cleavage, or linkage to a cellular ligand or other protein. [0210] An antibody described herein can have a sequence that has been modified to alter at least one constant region-mediated biological effector function relative to the corresponding wild type sequence. For example, in some embodiments, the antibody can be modified to reduce at least one constant region-mediated biological effector function relative to an unmodified antibody, e.g., reduced binding or increased binding to the Fc receptor (FcR). FcR binding can be reduced or increased by, for example, mutating the immunoglobulin constant region segment of the antibody at particular regions necessary for FcR interactions.
[0211] An antibody described herein can be modified to acquire or improve at least one constant region-mediated biological effector function relative to an unmodified antibody, e.g., to enhance FcyR interactions. For example, an antibody with a constant region that binds FcyRIIA, FcyRIIB and/or FcyRIIIA with greater affinity than the corresponding wild type constant region can be produced according to the methods described herein.
[0212] An antibody described herein can bind to tumor cells, such as an antibody against a cell surface receptor or a tumor antigen.

[0275] The effect of the tumor antigen binding domain and the binding domain that binds to an antigen on the immune cell together can be to cluster the antibody constructs or conjugates on cells expressing tumor antigen, and thus clustering immune cells such as antigen presenting cells around cancerous cells and at tumor sites resulting in activation of the antigen presenting cell effector functions. This can include the activation of the antigen on the antigen presenting cell when a an antibody construct is bound to its antigen, such as activation of CD40, CD47, TNFR2, DEC-205, PD-L1, CD36 mannose scavenger receptor 1, DC-SIGN, CLEC9A, CLEC12A, BDCA-2, OX40L, 41BBL, CD204, MARCO, CLEC5A, Dectin 1, Dectin 2, CLECIOA, CD206, CD64, CD32A, CD 16 A, HVEM, CD38, TREM2, CSFIR, or CD32B. In some embodiments, this activation of the antigen on the antigen presenting cell only occurs when the tumor targeting antibody construct is bound to its tumor antigen. An antigen presenting cell effector function can include antibody dependent cellular cytotoxicity (ADCC) of the tumor antigen expressing cell, which can occur when a bispecific tumor targeting antibody construct is bound to its tumor antigen. In some embodiments, ADCC of the tumor antigen expressing cell only occurs with a bispecific tumor targeting antibody construct is bound to its tumor antigen. In certain

Signaling can suitably be measured in vitro using a cell line expressing the tumor antigen bound by the target antigen binding domain, and primary antigen presenting cells isolated from a human subject. Signaling can be assessed as cytokine release, chemokine release, or increased expression of cell surface markers. In certain embodiments, a bispecific tumor targeting antibody construct density of greater than 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10,000 or more per cell, resulting from the bispecific tumor targeting antibody construct binding to the tumor antigen, induces ADCC of the cells expressing tumor antigen. ADCC can suitably be measured in vitro using a cell line expressing the tumor antigen bound by the target antigen binding domain, and cells such as NK cells and/or macrophages isolated from a human subject. ADCC can be determined by the frequency of remaining tumor antigen expressing cells in the co-culture.
[0276] In some embodiments, the antibody constructs as described herein can specifically bind to a tumor antigen in a cluster of constructs or conjugates, and this clustering can induce a signal in an antigen presenting cell. The constructs as described herein can specifically bind to a tumor antigen in a cluster of constructs, and this clustering can induce antibody dependent cellular cytotoxicity.

[0277] Sequences that can be used to produce antibodies for antibody constructs can include leader sequences. Leader sequences can include signal sequences. Leader sequences useful with the antibody construct and methods described herein can include, but are not limited to, an amino acid sequence comprising MRLP AQLLGLLLLWFPGS RC (SEQ ID NO: 847),
MDWTWRILFLVAAATGAHS (SEQ ID NO: 848), and MRAWIFFLLCLAGRALA (SEQ ID NO: 849).
[0278] An antibody construct can comprise an Fc region with an Fc domain. An Fc domain is a structure that can bind to Fc receptors. An antibody construct can comprise an Fc domain. Fc domains can be bound by Fc receptors (FcRs). Fc domains can be from antibodies. An Fc domain can be at least 80% homologous to an Fc domain from an antibody. An Fc region can be in a scaffold. An Fc region with an Fc domain can be in an antibody scaffold. An Fc region with an Fc domain can be in a non-antibody scaffold. An antibody construct can comprise an Fc region with an Fc domain in an antibody scaffold. An antibody construct can comprise an Fc region with an Fc domain in a non-antibody scaffold. An Fc domain can be in a scaffold. An Fc domain can be in an antibody scaffold. An Fc domain can be in a non-antibody scaffold. An antibody construct can comprise an Fc domain in an antibody scaffold. An antibody construct can comprise an Fc domain in a non-antibody scaffold. Fc domains of antibodies, including those of the present disclosure, can be bound by Fc receptors (FcRs). An Fc domain can be a portion of the Fc region of an antibody. FcRs can bind to an Fc domain of an antibody. FcRs can bind to an Fc domain of an antibody bound to an antigen. FcRs are organized into classes (e.g. , gamma (γ), alpha (a) and epsilon (ε)) based on the class of antibody that the FcR recognizes. The FcaR class can bind to IgA and includes several isoforms, FcaRI (CD89) and Fco jR. The FcyR class can bind to IgG and includes several isoforms, FcyRI (CD64), FcyRIIA (CD32a), FcyRIIB (CD32b), FcyRIIIA (CD 16a), and FcyRIIIB (CD 16b). An FcyRIIIA (CD 16a) can be an FcyRIIIA (CD 16a) F158 variant. An FcyRIIIA (CD 16a) can be an FcyRIIIA (CD 16a) V158 variant. Each FcyR isoform can differ in affinity to the Fc region of the IgG antibody. For example, FcyRI can bind to IgG with greater affinity than FcyRII or FcyRIII. The affinity of a particular FcyR isoform to IgG can be controlled, in part, by a glycan (e.g., oligosaccharide) at position CH2 84.4 of the IgG antibody. For example, fucose containing CH2 84.4 glycans can reduce IgG affinity for FcyRIIIA. In addition, GO glucans can have increased affinity for FcyRIIIA due to the lack of galactose and terminal GlcNAc moiety.
[0279] Binding of an Fc domain to an FcR can enhance an immune response. FcR-mediated signaling that can result from an Fc region binding to an FcR can lead to the maturation of immune cells. FcR-mediated signaling that can result from an Fc domain binding to an FcR can lead to the maturation of dendritic cells. FcR-mediated signaling that can result from an Fc domain binding to an FcR can lead to antibody dependent cellular cytotoxicity. FcR-mediated signaling that can result from an Fc domain binding to an FcR can lead to more efficient immune cell antigen uptake and processing. FcR-mediated signaling that can result from an Fc region binding to an FcR can lead to more efficient dendritic cell antigen uptake and processing. FcR- mediated signaling that can result from an Fc region binding to an FcR can increase antigen presentation. FcR-mediated signaling that can result from an Fc region binding to an FcR can increase antigen presentation by immune cells. FcR-mediated signaling that can result from an Fc region binding to an FcR can increase antigen presentation by antigen presenting cells. FcR- mediated signaling that can result from an Fc domain binding to an FcR can increase antigen presentation by dendritic cells. FcR-mediated signaling that can result from an Fc domain binding to an FcR can promote the expansion and activation of T cells. FcR-mediated signaling that can result from an Fc domain binding to an FcR can promote the expansion and activation of CD8+ T cells. FcR-mediated signaling that can result from an Fc domain binding to an FcR can influence immune cell regulation of T cell responses. FcR-mediated signaling that can result from an Fc domain binding to an FcR can influence immune cell regulation of T cell responses. FcR-mediated signaling that can result from an Fc domain binding to an FcR can influence dendritic cell regulation of T cell responses. FcR-mediated signaling that can result from an Fc domain binding to an FcR can influence functional polarization of T cells (e.g., polarization can be toward a ¾1 cell response).
[0280] The profile of FcRs on a dendritic cell (DC) can impact the ability of the DC to respond upon stimulation. For example, most DC can express both CD32A and CD32B, which can have opposing effects on IgG-mediated maturation and function of DCs: binding of IgG to CD32A can mature and activate DCs in contrast with CD32B, which can mediate inhibition due to phosphorylation of immunoreceptor tyro sine-based inhibition motif (ITIM), after CD32B binding of IgG. Therefore, the activity of these two receptors can establish a threshold of DC activation. Furthermore, the difference in functional avidity of these receptors for IgG can shift their functional balance. Hence, altering the Fc domain binding to FcRs can also shift their functional balance, allowing for manipulation (either enhanced activity or enhanced inhibition) of the DC immune response.
[0281] A modification in the amino acid sequence of the Fc domain of an antibody construct can alter the recognition of an FcR for the Fc domain. However, such modifications can still allow for FcR-mediated signaling. A modification can be a substitution of an amino acid at a residue (e.g., wildtype) for a different amino acid at that residue. A modification can permit binding of an FcR to a site on the Fc domain or region that the FcR may not otherwise bind to. A modification can increase the binding affinity of an FcR to the Fc domain that the FcR may have reduced binding affinity for. A modification can decrease binding affinity of an FcR to a site on the Fc domain that the FcR may have increased binding affinity for. A modification can increase the subsequent FcR-mediated signaling after Fc binding to an FcR.
[0282] An antibody construct can comprise an Fc region with at least one amino acid change as compared to the sequence of the wild-type Fc region. An antibody construct can comprise an Fc domain with at least one amino acid change as compared to the sequence of the wild-type Fc domain. An amino acid change in an Fc region can allow the construct to bind to at least one Fc receptor with greater affinity compared to a wild-type Fc region. An amino acid change in an Fc domain can allow the antibody construct to bind to at least one Fc receptor with greater affinity compared to a wild-type Fc domain. An Fc region can comprise an amino acid sequence having at least one, two, three, four, five, six, seven, eight, nine or ten modifications but not more than 40, 35, 30, 25, 20, 15, or 10 modifications of the amino acid sequence relative to the natural or original amino acid sequence. An Fc domain can comprise an amino acid sequence having at least one, two, three, four, five, six, seven, eight, nine or ten modifications but not more than 40, 35, 30, 25, 20, 15, or 10 modifications of the amino acid sequence relative to the natural or original amino acid sequence. An Fc region can be an Fc region of an IgGl antibody. An Fc region can contain an Fc domain. An Fc region can be an Fc domain.

A modification can comprise a substitution at more than one amino acid residue such as at 3 different amino acid residues including S298A/E333A/K334A (IgGl AAA), according to the EU index of Kabat.

Other substitutions in an IgG Fc domain that affect its interaction with FcRn are disclosed in U.S. Patent No. 9,803,023 (the disclosure of which is incorporated by reference herein).
[0297] An antibody construct can be a monoclonal anti-CD40 human antibody comprising a sequence of the IgGl isoform that has been modified from the wildtype IgGl sequence. A modification can comprise a substitution at more than one amino acid residue such as at 5 different amino acid residues including L235V/F243L/R292P/Y300L/P396L (SBT-040- G1VLPLL). The numbering of amino acids residues is according to the EU index. The 5 amino acid residues can be located in a portion of an antibody sequence which can encode an Fc region of the antibody and in particular, can be located in portions of the Fc region that can bind to Fc receptors (i.e., the Fc domain). A modification can comprise a substitution at more than one amino acid residue such as at 3 different amino acid residues including S298A/E333A/K334A (SBT-040-G1AAA). The 3 amino acid residues can be located in a portion of an antibody sequence which can encode an Fc region of the antibody and in particular, can be located in portions of the Fc region that can bind Fc receptors (i.e., the Fc domain).
[0298] Binding of Fc receptors to an Fc region can be affected by amino acid substitutions. For example, SBT-040-VLPLL is an antibody with an amino acid sequence of a heavy chain of human anti-CD40 monoclonal antibody with modifications to a wild-type IgGl Fc domain (L235V/F243L/R292P/Y300L/P396L). Binding of some Fc receptors to the Fc region of SBT- 040-VLPLL can be enhanced compared to wild-type by as result of the
L235V/F243L/R292P/Y300L/P396L amino acid modifications. However, binding of other Fc receptors to the Fc region of SBT-040-VLPLL can be reduced compared to wild-type by the L235V/F243L/R292P/Y300L/P396L amino acid modifications. For example, the binding affinities of SBT-040-VLPLLto FcyRIIIA and to FcyRIIA can be enhanced compared to wild- type whereas the binding affinity of SBT-040-VLPLL to FcyRIIB can be reduced compared to wild-type. Binding of Fc receptors to an Fc region of are affected by amino acid substitutions. SBT-040-G1AAA antibody is an antibody with an amino acid sequence of a heavy chain of a human anti-CD40 monoclonal antibody with modifications to a wild-type IgGl Fc domain (S298A/E333A/K334A). Binding of Fc receptors to an Fc region of SBT-040-G1AAA can be enhanced compared to wild-type as a result of the S298A/E333A/K334A amino acid
modification. However, binding of some Fc receptors to the Fc region of SBT-040-G1AAA can be reduced compared to wild-type by S298A/E333A/K334A amino acid modification. Binding affinities of SBT-040-G1AAA to FcyRIIIA can be enhanced compared to wild-type whereas the binding affinity of SBT-040-G1AAA to FcyRIIB can be reduced compared to wildtype.
[0299] In some embodiments, the heavy chain of a human IgG2 antibody can be mutated at cysteines as positions 127, 232, or 233. In some embodiments, the light chain of a human IgG2 antibody can be mutated at a cysteine at position 214. The mutations in the heavy and light chains of the human IgG2 antibody can be from a cysteine residue to a serine residue.
[0300] While an antibody construct of the present disclosure can comprise a first binding domain and a second binding domain (or, in some cases, a third binding domain) with wild-type or modified amino acid sequences encoding the Fc region or Fc domain, the modifications of the Fc region or the Fc domain from the wild-type sequence may not significantly alter binding and/or affinity of the binding domains. For example, binding and/or affinity of an antibody
constructcomprising a first binding domain and a second binding domain (or, in some cases, a third binding domain) and having the Fc domain modifications of SBT-040-G1WT, SBT-040- G1VLPLL, or SBT-040-G1AAA may not be significantly altered by modification of an Fc region or Fc domain amino acid sequence compared to a wild-type sequence. Modifications of an Fc region or Fc domain from a wild-type sequence may not alter binding and/or affinity of a first binding domain that binds, for example, to CD40 or DEC-205. Additionally, the binding and/or affinity of the binding domains described herein, for example, a first binding domain, a second binding domain (or, in some cases, a third binding domain), and an Fc domain modification selected from SBT-040-G1WT, SBT-040-G1VLPLL, and SBT-040-G1AAA, may be comparable to the binding and/or affinity of wild-type antibodies.
[0301] In some embodiments, the binding profile of the Fc domain for Fey receptors can be retained in the antibody construct or conjugate, which can allow for delivery of the antibody construct or conjugate into immune cell types comprising the Fey receptors and can further immune activation by Fey receptor signaling. In some embodiments, APCs can be activated by an antibody construct or conjugate as described herein when the antibody construct or conjugate is bound to a tumor cell, undergoes Fey receptor mediated uptake, or undergoes Fey receptor mediated Antibody Dependent Cellular Phagocytosis (ADCP). In some embodiments, the antibody construct or conjugate can retain weak or no Fey receptor binding to allow for maximal immune activation or decreased toxicity of the immune- stimulatory compound due to the primary delivery of the antibody construct or conjugate into tumor cells by antibody antigen mediated endocytosis.
[0302] In some embodiments, the antibody construct or conjugate can comprise an IgGl Fc domain variant comprising N297A, N297G, K322A/L234A/L235A, or L234F/L235E/P331S, and lacks binding to an Fey receptor but can retain binding to FcRN in the presence of the immune-modulatory compound to allow for lower delivery of the conjugate into tumor cells or immune cells.
[0303] In some embodiments, an antibody construct or conjugate can comprise an Fc domain with higher affinity to one or more Fey receptors, which can result in greater immune activation than for an antibody construct or conjugate with an Fc domain that can bind to one or more Fey receptors with lower affinity.

Immune-Stimulatory Compounds
[0304] In some embodiments, the immune- stimulatory conjugates described herein further comprise an immune- stimulatory compound. An immune- stimulatory compound can be a small molecule, a compound or molecule that binds to a protein target and can activate the target protein' s function, or a compound that binds to a protein target and can inhibit the protein target's function, resulting in immune stimulation or modulation. In certain embodiments, an immune- stimulatory compound of a conjugate (i.e., attached to an antibody construct either directly or via a linker) can stimulate or activate its protein target with no or minimal processing of the conjugate. In certain embodiments, an immune- stimulatory compound of a conjugate (i.e., attached to an antibody construct either directly or via a linker) can inhibit its protein target with no or minimal processing of the conjugate. In this context, processing refers to degradation of the antibody construct or cleavage of the linker to liberate the immune- stimulatory compound or degredation product of the conjugate containing the immune- stimulatory compound. In certain embodiments, the protein target of the immune- stimulatory compound is an extracellular protein target and is located on the cell surface membrane or cellular compartments in communication with the cell surface, such as in the endoplasmic reticulum (ER). In certain embodiments, the protein target is intracellular, such as in the cytoplasm.
[0305] In some embodiments, an immune- stimulatory compound can activate immune cells. In some embodiments, an immune- stimulatory compound can reduce inhibition of immune cells. In some embodiments, an immune- stimulatory compound can stimulate immune activation by triggering degradation of a protein target.
[0306] In some embodiments, an immune- stimulatory compound can be a molecule or
compound whose action on its target can lead to immune stimulation by direct immune cell activation. In some embodiments, the immune activation can be indirect by alteration of the immune suppressive microenvironment of a tumor (e.g., removing an immunosuppressive signal or altering an immunosuppressive state). In some embodiments, the immune- stimulatory compound's activity can be both direct and indirect. In certain embodiments, an immune- stimulatory conjugate can alter the activity of its protein target in cells having an antigen bound by the conjugate as compared to activity of the protein target in non- antigen bearing cells (i.e., the immune- stimulatory activity is antigen-specific).
[0307] In certain embodiments, the immune- stimulatory compound can be coupled to an Fc domain or other portion of an antibody construct via a linker. In each of the embodiments described herein, the immune- stimulatory compound can be coupled to the antibody construct via a linker.
[0308] An immune- stimulatory compound can be a Pattern recognition receptor (PRR) agonist. Pattern recognition receptors (PRRs) can recognize pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). A PRR can be membrane bound. A PRR can be cytosolic. A PAMP molecule can be a toll-like receptor agonist. A PRR can be a to 11- like receptor (TLR). A PRR can be RIG-I-like receptor. A PRR can be a receptor kinase. A PRR can be a C-type lectin receptor. A PRR can be a NOD-like receptor. A PRR can be TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR7, TLR8, TLR9, TLR 10, TLR11, TLR 12, or TLR13.
[0309] A PRR agonist can be a damage-associated molecular pattern (DAMP) molecule. A DAMP molecule can be an intracellular protein. A DAMP molecule can be a heat-shock protein. A DAMP molecule can be an HMGB 1 protein. A DAMP molecule can be a protein derived from the extracellular matrix that is generated after tissue injury. A DAMP molecule can be a hyaluronan fragment. A DAMP molecule can be DNA. A DAMP molecule can be RNA. A DAMP molecule can be an S 100 molecule. A DAMP molecule can be a nucleotide(s). A DAMP molecule can be ATP. A DAMP molecule can be a nucleoside(s). A DAMP molecule can be an adenosine. A DAMP molecule can be uric acid.
[0310] In some embodiments, the immune- stimulatory compound can be a Toll-like receptor agonist, a RIG-I agonist, a STING agonist, a GPCR agonist, an ion channel agonist, a membrane transporter agonist, an ER protein agonist, a beta-catenin pathway inhibitor, a kinase inhibitor, a TNIK inhibitor, a Tankyrase inhibitor, a GPCR antagonist, an HSP90 inhibitor, or an AAA- ATPase p97 inhibitor. In some embodiments, the immune- stimulatory compound can be a Tolllike receptor agonist, a RIG-I agonist or a STING agonist. In some embodiments, the immune- stimulatory compound can be a beta-catenin pathway inhibitor, such as a TNIK inhibitor or a Tankyrase inhibitor.
[0311] In some embodiments, the immune- stimulatory compound is a Toll-like receptor agonist.
A toll- like receptor agonist can be any molecule that acts as an agonist to at least one toll- like receptor. In some embodiments, the Toll- like receptor agonist can be a molecule selected from a
CpG oligonucleotide, Poly G10, Poly G3, Poly I:C, a lipopolysaccharide, a zymosan, a bacterial flagella protein (e.g., flagellin), PamjCSIQ, PamCysPamSK4, dsRNA, ssRNA, a diacylated lipopeptide, a bacterial lipoprotein, a triacylated lipoprotein, lipoteichoic acid, or a peptidoglycan (such as a bacterial peptidoglycan).
[0312] In some embodiments, an immune- stimulatory compound is not a toll-like receptor agonist. In some embodiments, a toll- like receptor agonist is not a naturally occurring molecule, such as CpG oligonucleotide, a lipopolysaccharide, a zymosan, a bacterial flagella protein (e.g., flagellin), PamjCSIQ, PamCysPamSIQ, dsRNA, ssRNA, a diacylated lipopeptide, a bacterial lipoprotein, a triacylated lipoprotein, lipoteichoic acid, or a peptidoglycan (such as a bacterial peptidoglycan). In some further embodiments, a toll- like receptor agonist is not a synthetic nucleic acid, such as Poly G10, Poly G3 or Poly I:C.
[0313] In some embodiments, a toll- like receptor agonist can be a synthetic small molecule. A to 11- like receptor agonist can be imiquimod. A to 11- like receptor agonist can be CL307. A to 11- like receptor agonist can be S-27609. A toll-like receptor agonist can be resiquimod. A toll-like receptor agonist can be UC-IV150. A to 11- like receptor agonist can be gardiquimod. A to 11- like receptor agonist can be motolimod. A toll-like receptor agonist can be a motolimod analog. A to 11- like receptor agonist can be VTX-1463. A to 11- like receptor agonist can be GS-9620. A tolllike receptor agonist can be GSK2245035. A toll- like receptor agonist can be TMX-101. A tolllike receptor agonist can be TMX-201. A toll- like receptor agonist can be TMX-202. A toll- like receptor agonist can be isatoribine. A toll-like receptor agonist can be AZD8848. A toll-like receptor agonist can be MEDI9197. A to 11- like receptor agonist can be 3M-051. A to 11- like receptor agonist can be 3M-852. A toll-like receptor agonist can be 3M-052. A toll-like receptor agonist can be 3M-854A. A toll-like receptor agonist can be S-34240. A toll-like receptor agonist can be CL663. A to 11- like receptor agonist can be KU34B.
[0314] A RIG-I agonist can be KIN1148. A RIG-I agonist can be SB-9200. A RIG-I agonist comprises a 5'ppp-dsRNA.

[0329] In certain embodiments, an immune- stimulatory compound of a conjugate (i.e, attached to an antibody construct either directly or via a linker) has a biological potency no less than at least about 0.33%, about 1%, about 5%, about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85%, about 90%, about 95%, or about 100% of the potency of the control (free) immune- stimulatory compound (i.e., not attached to an antibody construct).
[0330] The specificity of the antigen-binding domain (of a conjugate) for an antigen can be influenced by the attachment of an immune- stimulatory compound to an antibody construct. In various embodiments, an antigen-binding domain of the conjugate can bind to its antigen with at least about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85%, about 90%, about 95%, or about 100% of the specificity of the antigen-binding domain for the antigen in the absence of attachment of the immune- stimulatory compound.
[0331] The specificity of the Fc domain (of a conjugate) for an Fc receptor can be influenced by the attachment site of an immune- stimulatory compound (directly or via a linker). In some embodiments, the Fc domain of a conjugate retains the specificity of the unconjugated Fc domain to bind to an Fc receptor. In specific embodiments, the Fc domain of the conjugate can bind to an Fc receptor with at least about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85%, about 90%, about 95%, or about 100% of the specificity of the Fc domain to the Fc receptor in the absence of attachment of the immune- stimulatory compound.
[0332] In some embodiments, the Fc domain of a conjugate has an altered specificity for an Fc receptor relative to the corresponding unconjugated Fc domain. In specific embodiments, the Fc domain of the conjugate can bind to an Fc receptor with at least about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85%, about 90%, about 95%, or about 100% loss of specificity of the Fc domain to the Fc receptor as compared to an Fc domain of a conjugate not attached to an immune- stimulatory compound (in the absence of the immune- stimulatory compound). In some embodiments, the Fc domain is an Fc null.
[0333] The affinity of the antigen-binding domain of a conjugate to an antigen can be influenced by the attachment of an immune- stimulatory compound attached to the antibody construct. In some embodiments, the affinity of the antigen-binding domain of the conjugate for binding to an antigen is at least about 1%, about 5%, about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85%, about 90%, about 95%, or about 100% of the affinity of the antigen-binding domain to the antigen in the absence of the immune- stimulatory compound (not attached to the antibody construct).
[0334] The affinity of the Fc domain to an Fc receptor of a conjugate can be influenced by attachment of an immune- stimulatory compound to the antibody construct (either directly or indirectly). In some embodiments, the Fc domain of the conjugate can bind to an Fc receptor with at least about 1%, about 5%, about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85%, about 90%, about 95%, or about 100% of the affinity of the Fc domain to the Fc receptor in the absence of the immune- stimulatory compound attached to the antibody construct. In some embodiments, the Fc domain of the conjugate can bind to an Fc receptor with a reduced affinity of at least about 1%, about 5%, about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85%, about 90%, about 95%, or about 100% of the affinity of the Fc domain to the Fc receptor in the absence of attachment the immune- stimulatory compound (directly or via a linker). In some embodiments, the Fc domain is an Fc null.
[0335] The Kd for binding of an antigen-binding domain to an antigen when an immune- stimulatory compound is attached to the antibody construct can be about 2 times, about 3 times, about 4 times, about 5 times, about 6 times, about 7 times, about 8 times, about 9 times, about 10 times, about 15 times, about 20 times, about 25 times, about 30 times, about 35 times, about 40 times, about 45 times, about 50 times, about 60 times, about 70 times, about 80 times, about 90 times, about 100 times, about 110 times, or about 120 times greater than the Kd for binding of the antigen binding domain to the antigen in the absence of the immune- stimulatory compound attached to the antibody construct.
[0336] In some embodiments, the Kd for binding of an Fc domain to an Fc receptor when an immune- stimulatory compound is attached to an antibody construct can be about 2 times, about 3 times, about 4 times, about 5 times, about 6 times, about 7 times, about 8 times, about 9 times, about 10 times, about 15 times, about 20 times, about 25 times, about 30 times, about 35 times, about 40 times, about 45 times, about 50 times, about 60 times, about 70 times, about 80 times, about 90 times, about 100 times, about 110 times, or about 120 times greater than the Kd for binding of the Fc domain to the Fc receptor without the immune- stimulatory compound attached to the antibody construct.
[0337] In some embodiments, the Kd for binding of an Fc domain to a Fc receptor when the immune- stimulatory compound is attached to the antibody construct can be about 2 times, about 3 times, about 4 times, about 5 times, about 6 times, about 7 times, about 8 times, about 9 times, about 10 times, about 15 times, about 20 times, about 25 times, about 30 times, about 35 times, about 40 times, about 45 times, about 50 times, about 60 times, about 70 times, about 80 times, about 90 times, about 100 times, about 110 times, or about 120 times less than the Kd for binding of the Fc domain to the Fc receptor when the immune- stimulatory compound is not attached to the antibody construct.
[0338] Affinity is the strength of the sum total of noncovalent interactions between a single binding site of a molecule, for example, an antibody, and the binding partner of the molecule, for example, an antigen. The affinity can also measure the strength of an interaction between an Fc domain of an antibody and an Fc receptor. Unless indicated otherwise, as used herein, "binding affinity" refers to intrinsic binding affinity which reflects a 1: 1 interaction between members of a binding pair (e.g., antibody and antigen or Fc domain and Fc receptor). The affinity of a molecule
X for its partner Y can generally be represented by the dissociation constant (Kd). Affinity can be measured by common methods known in the art. Specific illustrative and exemplary
embodiments for measuring binding affinity are described in the following. [0339] In some embodiments, an antibody construct (e.g., an antibody or antigen-binding fragment thereof) can have a dissociation constant (Kd) for an antigen or Fc receptor of about 1 μΜ, about 100 nM, about 10 nM, about 5 nM, about 2 nM, about 1 nM, about 0.5 nM, about 0.1 nM, about 0.05 nM, about 0.01 nM, or about 0.001 nM or less (e.g., 10"6 or less, 10"8 M or less, from 10"8 M to 10"13 M, or from 10"9 M to 10"13 M). An affinity matured antibody can be an antibody with one or more alterations in one or more complementarity determining regions (CDRs), compared to a parent antibody, which may not possess such alterations, such alterations resulting in an improvement in the affinity of the antibody for antigen. These antibodies can bind to their antigen with a Kd of about 5xl0"9 M, about 2xl0"9 M, about lxlO"9 M, about 5xl0"10 M, about lxlO"10 M, about 5xl0"u M, about lxlO"11 M, about 5xl0"12 M, about lxlO"12 M, or less. In some embodiments, the antibody construct (e.g., affinity matured antibody) can have an increased affinity of at least 1.5-fold, 2-fold, 2.5-fold, 3-fold, 4-fold, 5-fold, 10-fold, 20-fold, or greater as compared to an antibody construct without alterations in one or more CDRs.
[0340] Kd can be measured by any suitable assay. For example, Kd can be measured by a radiolabeled antigen binding assay (RIA). For example, Kd can be measured using surface plasmon resonance assays (e.g., using a BIACORE®-2000 or a BIACORE®-3000).
[0341] The molar ratio or drug-antibody ratio of a conjugate refers to the number of immune- stimulatory compounds attached to an antibody construct in a conjugate or preparation of immune- stimulatory conjugates. The molar ratio can refer to the number of immune- stimulatory compounds attached (e.g., conjugated) to an antibody construct of a particular conjugate and is an integer, such as from 0-8 or 0 to 20. The molar ratio can also refer to the average number of immune- stimulatory compounds attached to antibody constructs in a mixture of conjugates, such as in a pharmaceutical composition.
[0342] The molar ratio can be determined, for example, by Liquid Chromatography/Mas s Spectrometry (LC/MS), in which the number of immune- stimulatory compounds attached to the antibody construct can be directly determined. Additionally, as non- limiting examples, the molar ratio can be determined based on hydrophobic interaction chromatography (HIC) peak area, by liquid chromatography coupled to electrospray ionization mass spectrometry (LC-ESI-MS), by UV/Vis spectroscopy, by reversed-phase-HPLC (RP-HPLC), or by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS).
[0343] In some embodiments, the molar ratio of immune- stimulatory compound to antibody construct can be less than 8 or less than 20. In other embodiments, the molar ratio of immune- stimulatory compound to an antibody construct can be 8, 7, 6, 5, 4, 3, 2, or 1. In some embodiments, the average molar ratio of immune- stimulatory compounds to antibody constructs in a composition can be less than 8, such as about 3 to 5 or about 2. In other embodiments, the average molar ratio of immune- stimulatory compounds to antibody constructs in a composition can be 8, 7, 6, 5, 4, 3, 2, or 1 or fractions hereof, or such as about 3.5 or about 1.8.
[0344] In a conjugate, an antibody construct (e.g., an antibody) can be linked to an immune- stimulatory compound in such a way that the antibody construct can still bind to an antigen and the Fc domain of the antibody construct can still bind to an FcR. In a conjugate, an antibody construct can be linked to an immune- stimulatory compound in such a way that the linking does not interfere with the ability of the antigen binding domain of the antibody construct to bind to its antigen, the ability of the Fc domain of the antibody construct to bind to an FcR, or FcR- mediated signaling resulting from the Fc domain of the antibody construct binding to an FcR. In a conjugate, an immune- stimulatory compound can be linked to an antibody construct in such a way that the linking does not interfere with the ability of the immune- stimulatory compound to bind to its receptor or otherwise can induce a biological effect. In some embodiments, a conjugate can produce stronger immune stimulation and a greater therapeutic window than components of the conjugate alone. For example, in an anti-tumor or anti-CD40 antibody linked to a TLR agonist, the combination of CD40 agonism, TLR agonism and an accessible Fc domain of the anti-CD40 antibody resulting in FcR-mediated signaling can produce stronger immune stimulation and a greater therapeutic window than the CD40 agonism, TLR agonism, or the FcR- mediated signaling alone.
[0345] In some embodiments, a conjugate can comprise a first binding domain, wherein the first binding domain contributes to immune- stimulatory activity; a first and second binding domain, wherein the second binding domain contributes to immune stimulatory activity; or a first binding domain and second binding domain, wherein the first binding domain and the second binding domain contribute to immune- stimulatory activity. The first binding domain and the second binding domain can contribute to the same immune- stimulatory activity. The first binding domain and the second binding domain can contribute to different immune- stimulatory activities.
[0346] In some embodiments, a conjugate in which the first binding domain contributes to immune- stimulatory activity can increase the immune- stimulation of the conjugate.
Immune-Stimulatory Compound Potency and Binding Activity
[0347] In certain embodiments, an immune- stimulatory compound has similar activity when bound to the antibody construct as when not bound to the antibody construct. In certain embodiments, the immune- stimulatory compound maintains the same level of potency and/or binding affinity when bound to an antibody construct as compared to the unbound immune- stimulatory compound. [0348] For many known antibody-drug conjugates, the payload/drug of the conjugate is a cytotoxic agent that acts on an intracellular target. The antibody generally targets a certain tumor marker on the surface of a cancer cell and upon binding of the antibody to the tumor cell, the cancer cell then internalizes the antibody-cytotoxic agent conjugate. The cytotoxic agent is released within the cell through enzymatic cleavage or other cleavage of the agent's linkage to the antibody or through enzymatic degradation of the antibody. The released cytotoxic agent or degredation product acts on the intracellular target of the cytotoxic agent to kill the cancer cell. Important to the mechanism of action of many antibody-cytotoxic agent conjugates is: (1) that the cytotoxic agent is bound to the antibody with a linker, wherein the linker is not cleaved until exposed to enzymes or conditions inside a target cell, e.g., a cancer cell; (2) that the cytotoxic agent is released from the antibody inside of the cell to perform its cytotoxic function; and (3) that the cytotoxic agent is not active or minimally active (i.e., in a prodrug form) when bound to the antibody such that the cytotoxic agent does not indiscriminately kill cells and harm organ systems distributed thorught the body on the path to the cancer cell.
[0349] In certain aspects, the immune- stimulatory conjugates of the disclosure operate under a different paradigm from such antibody-cytotoxic agent conjugates. The immune- stimulatory conjugates of the disclosure can be designed in a way that the payload immune- stimulatory compound has the same potency, similar potency, or increased potency when bound to the antibody construct as compared to the unbound immune- stimulatory compound and in contrast to antibody-cytotoxic agent conjugates. The immune- stimulatory conjugates of the disclosure may perform, and in some cases preferably perform, the intended function of the compound, i.e., stimulate or modulate the function of immune cells or other target cells, without prior release of the compound from the conjugate (i.e., while attached to the antibody construct). The features of the immune- stimulatory compound-conjugates and assays that enable these functions and others are described further herein.
[0350] The potency of the immune- stimulatory compound of the conjugate may not be significantly reduced relative to the potency of the un-attached (free) immune- stimulatory compound. In particular, the potency of the immune- stimulatory compound of the conjugate (i.e., as part of the conjugate or covalently bound to the antibody construct) is preferably no greater than 500-fold less, no greater than 400-fold less, no greater than 300-fold less, no greater than 200-fold less, no greater than 100-fold less, no greater than 50-fold less, or no greater than 10- fold less than the potency of a control compound, wherein the control compound is the unbound immune- stimulatory compound. For example, for an immune- stimulatory conjugate represented by the structure: Ab - L - C, wherein A is an antibody construct, L is a linker, and C is an immune- stimulatory compound, the immune- stimulatory activity of C of the conjugate A - L - C is preferably no greater than 500-fold less, no greater than 400-fold less, no greater than 300-fold less, no greater than 200-fold less, no greater than 100-fold less, no greater than 50-fold less, or no greater than 10-fold less than the potency of the immune- stimulatory compound, C, unbound from the immune- stimulatory conjugate, A - L - C, in the absence of processing of the immune- stimulatory conjugate in a cell.
[0351] In particular embodiments, the potency of an immune- stimulatory compound of the conjugate (i.e., covalently bound to the antibody construct) is near or equivalent to the potency of the unbound immune- stimulatory compound, such as within about 10-fold, within about 8-fold, within about 5-fold, or within about 2-fold of the potency of the unbound immune- stimulatory compound. The potency of the immune- stimulatory compound of the conjugate may be greater than the potency of the unbound immune- stimulatory compound, such as about 2-fold or greater, 5-fold or greater, 10-fold or greater, 100-fold or greater, 200-fold or greater, 300-fold or greater, 400-fold or greater, or even 500-fold or greater than the potency of the unbound immune- stimulatory compound. In certain embodiments, the tolerability of an immune- stimulatory compound when part of a construct is greater than the tolerability of the unbound immune- stimulatory compound in a subject.
[0352] In certain embodiments, the potency of the immune- stimulatory compound when bound to a 5-500 atom linker is the same, similar, or increased as compared to the potency of the immune- stimulatory compound not bound to the 5-500 atom linker. In certain embodiments, the tolerability of the immune- stimulatory compound in a subject when bound to a 5-500 atom linker is the same, similar, or increased as compared to the tolerability of the immune- stimulatory compound not bound to the 5-500 atom linker.
[0353] The "5-500 atom linker" referred to herein has 5 to 500 consecutive atoms from end to end. When attached to an immune- stimulatory compound and to an antibody construct, a 5-500 atom linker has 5-500 consecutive atoms between the point of attachment to the immune- stimulatory compound and the point of attachment to the antibody construct. A 5-500 atom linker can have, for example, from about 50 to about 500 atoms, such as about 50 to about 300 atoms or such as about 50 to about 200 atoms. A 5-500 atom linker can have, for example, from about 25 to about 500 atoms, such as about 25 to about 300 atoms or such as about 25 to about 200 atoms. In certain embodiments, the linker includes one or more peptide bonds. In certain embodiments, the linker includes one or more ethylene glycol groups. In certain embodiments, the linker includes a peptide backbone and one or more side chains. In certain embodiments, the linker is not cleaved from the immune- stimulatory compound in the assay evaluating potency.
[0354] Exemplary 5-500 atom linkers include Fleximer linkers, linkers with one or more carbamate or amide linkages and linkers represented by the formula:
Figure imgf000209_0001
antibody construct, R is hydrogen, Ci-ioalkyl, sulfonate and methyl sulfonate and the wavy line indicates an attachment to the rest of the linker or to the immune- stimulatory compound.
[0355] In some embodiments, the linker is a non-cleavable linker. Examples of non-cleavable linkers include the following:
Figure imgf000209_0002
wherein Rx is a reactive moiety for attachment to the antibody construct, R is hydrogen, Q. loalkyl, sulfonate and methyl sulfonate and the wavy line indicates an attachment to the rest of the linker or to the immune- stimulatory compound.
[0356] Further examples of non-cleavable linkers include:
Figure imgf000210_0001
wherein the wavy line indicates an attachment to the rest of the linker or to the immune- stimulatory compound.
[0357] In some embodiments, the potency of an immune- stimulatory compound when bound to a 5-500 atom linker can be no greater than 500-fold less, no greater than 400-fold less, no greater than 300-fold less, no greater than 200-fold less, no greater than 100-fold less, no greater than 50-fold less, or no greater than 10-fold less than the potency of a control compound, wherein the control compound is the unbound immune- stimulatory compound. For example, for compounds suitable for use in the conjugates of the disclosure, the immune- stimulatory activity of the immune- stimulatory compound bound to a 5-500 atom linker, represented by the formula: C - L* , wherein L* is a 5-500 atom linker, is preferably no greater than 500-fold less, no greater than 400-fold less, no greater than 300-fold less, no greater than 200-fold less, no greater than 100- fold less, no greater than 50-fold less, or no greater than 10-fold less than the potency of the immune- stimulatory compound, C, unbound from linker L*.
[0358] In particular embodiments, the potency of the immune- stimulatory compound bound to a 5-500 atom linker is equivalent to the potency of the unbound immune- stimulatory compound, such as within about 10-fold, within about 8-fold, within about 5-fold, or within about 2-fold of the potency of the unbound immune- stimulatory compound. One exemplary embodiment is depicted in FIGURE 16, wherein the designed inhibitor bound to a linker surrogate, L* as discussed herein, displays a similar EC50 value relative to the compound unbound from the linker. In certain embodiments, the potency of the immune- stimulatory compound bound to a 5- 500 atom linker may be greater than the potency of the unbound immune- stimulatory compound, such as about 2-fold or greater, 5-fold or greater, 10-fold or greater, 100-fold or greater, 200-fold or greater, 300-fold or greater, 400-fold or greater than 500-fold than the potency of the unbound immune- stimulatory compound. In certain embodiments, the tolerability of the immune- stimulatory compound bound to an antibody construct by a 5-500 atom linker may be greater than the potency of the unbound immune- stimulatory compound, such as about 2-fold or greater, 5-fold or greater, 10-fold or greater, 100-fold or greater, 200-fold or greater, 300-fold or greater, 400-fold or greater than 500-fold than the potency of the unbound immune- stimulatory compound.
[0359] "Unbound immune- stimulatory compound" or reference to an immune- stimulatory compound without specifying its connection to a linker or antibody, as used herein, refers to a compound with immune- stimulatory activity that is not bound to a linker (such as the linkers described herein) and not part of an immune- stimulatory conjugate, as described herein. In certain embodiments, the "control compound" as compared to a conjugate or linker-bound immune- stimulatory compound is the unbound immune- stimulatory compound. Unbound immune- stimulatory compounds are generally not suitable for direct attachment to an antibody construct (such as an antibody) without a linker, such as those described herein. An unbound immune- stimulatory compound may be a synthetic precursor to an immune- stimulatory conjugate, wherein the immune- stimulatory compound may be modified by attaching a linker such as the linkers described herein and optionally further bound to an antibody to form an immune- stimulatory conjugate.
[0360] In certain aspects, the potency of the immune- stimulatory compound of the conjugate, the potency of the immune- stimulatory compound bound to a 5-500 atom linker, and the potency of the unbound immune- stimulatory compound may be determined using a PBMC assay as described in Example 7.
[0361] The immune- stimulatory conjugates of the disclosure can be engineered to maintain, not significantly reduce, or increase the potency of the immune- stimulatory compound in the conjugate relative to the unbound immune- stimulatory compound. In certain embodiments, a highly potent immune- stimulatory compound, e.g., the unbound immune- stimulatory agent has an EC50 of less than 500 nM, such as less than 400 nM, such as less than 300 nM, such as less than 200 nM, such as less than 100 nM, such as less than 50 nM, or such as less than 10 nM, is used as an immune- stimulatory compound of the conjugates herein.
[0362] In designing an immune- stimulatory conjugate of the disclosure, an unbound immune- stimulatory compound can be bound to a linker at a position on the immune- stimulatory compound that does not interfere with the ability of the immune- stimulatory compound to interact with its protein binding site. For example, a linker can be attached to an immune- stimulatory compound at a solvent accessible site on the compound when the compound would be bound to its protein target. For example, as depicted in FIGURE 20A, an antibody 3405 bound to a linker 3410 is bound to an immune- stimulatory compound 3415. The linker 3410 is bound to a position of the immune- stimulatory compound 3415 such that the linker 3410 and/or antibody 3405 does not interfere with the interaction between the immune- stimulatory compound 3415 and the active site 3425 of a target protein 3420 (FIGURE 20B). The linker 3410 may extend out from the active site 3425 of the target protein 3420 at the solvent/active site interface 3430.
[0363] The potency of the unbound immune- stimulatory compound may also be evaluated relative to the potency of the immune- stimulatory compound bound to a 5-500 atom linker as a surrogate for the immune- stimulatory conjugate. Evaluating the potency of the immune- stimulatory compound bound to a 5-500 atom linker, as described herein, can be predictive of the activity of the immune- stimulatory compound in the conjugate. For example, as depicted in
FIGURE 20C, a linker 3410 is bound to an immune- stimulatory compound 3415. The linker 3410 is bound to a portion of the immune- stimulatory compound 3415 such that the linker 3410 does not interfere with the interaction between the immune- stimulatory compound 3415 and the active site 3425 of a target protein 3420. FIGURE 20D depicts the unbound immune- stimulatory compound 3415 in the active site 3425 of a target protein 3420.
[0364] In certain embodiments, the binding position of the linker 3410 on the immune- stimulatory compound 3415 may be determined using target protein crystal structures and active site protein modeling. As depicted in FIGURE 15B and FIGURE 15C an immune- stimulatory compound, such as the left-hand compound of FIGURE 15A, may be modeled in an active site of a target protein and the positioning of the linker attachment to the immune- stimulatory compound may be selected based on this modeling. For example, the modeling may indicate that positioning of a linker on the 4-position of the benzimidazole of the left-hand compound of
FIGURE 15A would extend from the active site and not interfere with the active site interactions of the compound as depicted in FIGURE 15B and FIGURE 15C.
[0365] The linker can be covalently bound to the immune- stimulatory compound at a position on the immune- stimulatory compound that is at or near the solvent interface of the protein active site, as determined by modeling of the immune- stimulatory compound in the protein active site. In certain embodiments, the linker is covalently bound to the immune- stimulatory compound at a position on the immune- stimulatory compound such that when the immune- stimulatory compound is positioned in the protein active site, the linker extends out from the protein active site into the solvent, as determined by modeling of the immune- stimulatory compound in the protein active site. FIGURE 17B and FIGURE 17C depict binding of the left-hand compound of FIGURE 17A. A linker may be positioned on the phenyl ring to extend out of the protein active site, e.g., see left portion of right-hand compound of FIGURE 17A. FIGURE 18B and FIGURE 18C depict binding of the left-hand compound of FIGURE 18A. The trifluoromethyl substituent on the phenyl group may be replaced with a linker at this position to extend out of the protein active site, e.g., see left portion of right-hand compound of FIGURE 18A. FIGURE 19B and FIGURE 19C depict binding of the left-hand compound of FIGURE 19A with the linker (left side of right hand molecule) positioned to extend out of the protein active site.
[0366] In certain embodiments, the immune- stimulatory compounds have similar binding affinity to a protein active site when bound to the antibody construct as when not bound to the antibody construct. In certain embodiments, the immune- stimulatory compounds maintain the binding affinity to a protein active site when bound to an antibody construct as compared to the binding affinity of the unbound immune- stimulatory compound.
[0367] In certain embodiments, the Kd for binding of the immune- stimulatory compound of the conjugate to a protein active site is no greater than 50 times the Kd for binding of a control compound to the protein active site, wherein the control compound is the unbound immune- stimulatory compound. (As used herein, the phrase "of the conjugate" refers to the immune- stimulatory compounds while attached to the antibody construct, usually via a linker(s).) For example, the Kd for binding of the immune- stimulatory compound of the conjugate to the protein active site may be no greater than 40 times, no greater than 30 times, no greater than 20 times, or no greater than 10 times the Kd for binding of the unbound immune- stimulatory compound to the protein active site. In certain embodiments, the Kd for binding of the immune- stimulatory compound of the conjugate to the protein active site is no greater than 10 times the Kd for binding of a control compound to the protein active site, wherein the control compound is the unbound immune- stimulatory compound. The Kd for binding of the immune- stimulatory compound of the conjugate to the protein active site may be no greater than 9 times, no greater than 8 times, no greater than 7 times, no greater than 6 times, no greater than 5 times, no greater than 4 times, no greater than 3 times, or no greater than 2 times the Kd for binding of the unbound immune- stimulatory compound to the protein active site.
[0368] In certain embodiments, the Kd for binding of the immune- stimulatory compound of the conjugate to the protein active site is close to or equivalent to the Kd for binding of a control compound, such as within about 10 times, within about 8 times, within about 6 times, within about 5 times, within about 4 times, within about 3 times or within about 2 times the binding affinity of the unbound immune- stimulatory compound. In certain embodiments, the Kd for binding of the immune- stimulatory compound of the conjugate to the protein active site is less than the Kd for binding of the unbound immune- stimulatory compound.
[0369] In certain embodiments, the binding affinity to a protein active site of an immune- stimulatory compound bound to a 5-500 atom linker, as described herein, is the same, similar, or increased as compared to the binding affinity of the immune- stimulatory compound not bound to the 5-500 atom linker. In particular embodiments, the binding affinity of the immune- stimulatory compound when bound to a 5-500 atom linker is no greater than 40 times, no greater than 30 times, no greater than 20 times, or no greater than 10 times the Kd for binding of the unbound immune- stimulatory compound to the protein active site.
[0370] In certain embodiments, the binding affinity to a protein active site of the immune- stimulatory compound bound to a 5-500 atom linker is no greater than 10 times the Kd for binding of a control compound to the protein active site, wherein the control compound is the unbound immune- stimulatory compound. The binding affinity to a protein active site of the immune- stimulatory compound bound to a 5-500 atom linker may be no greater than 9 times, no greater than 8 times, no greater than 7 times, no greater than 6 times, no greater than 5 times, no greater than 4 times, no greater than 3 times, or no greater than 2 times the Kd for binding of the unbound immune- stimulatory compound to the protein active site.
[0371] In certain embodiments, the binding affinity to a protein active site of the immune- stimulatory compound bound to a 5-500 atom linker is close to or equivalent to the Kd for binding of a control compound, such as within about 10 times, within about 8 times, within about 6 times, within about 5 times, within about 4 times, within about 3 times or within about 2 times the binding affinity of the unbound immune- stimulatory compound. In certain embodiments, the binding affinity to a protein active site of the immune- stimulatory compound bound to a 5-500 atom linker is less than the Kd for binding of the unbound immune- stimulatory compound.
[0372] In certain aspects, the binding affinity of the immune- stimulatory compound of the conjugate, the binding affinity of the immune- stimulatory compound bound to a 5-500 atom linker, and the binding affinity of the unbound immune- stimulatory compound may be determined using an assay such as a Bio-layer Interferometry (BLI) as described in Example 8.
[0373] In certain embodiments, the immune- stimulatory compound binds to a cell membrane or ER protein target. In certain embodiments, the immune- stimulatory compound binds to a cell membrane or ER protein target and is other than a TLR agonist. In some embodiments, the immune- stimulatory compound is a kinase inhibitor and the protein active site is a kinase active site. Kinase inhibitors are a type of enzyme inhibitor that block the action of at least one protein kinase, which are enzymes that can add at least one phosphate group to a protein and thereby modulate its function or activity. In certain embodiments, the immune- stimulatory compound is a kinase inhibitor. In some embodiments, the kinase inhibitor targets a protein kinase that acts on both serine and threonine residues. In certain embodiments, the kinase inhibitor targets protein kinases that act on tyrosine residues. In certain embodiments, the kinase inhibitor targets protein kinases that act on serine, threonine and tyrosine residues. In other embodiments, the kinase inhibitor targets protein kinases that act on amino acids other than serine, threonine and tyrosine, such as histine kinases. The kinase inhibitors may target ALK, Bcr-Abl, BRAF, BTK, c-KIT, EGFR, ErbB2, JAK, MEK, MET, PDGFRB, RET, ROS 1, Syk, SRC, TGFpR2, TNIK, TNKS, TNKS2, TrkA, TrkB, TrkC, VEGFR1, VEGFR2, VEGFR3, PI3K, AKT, mTOR, and
combinations thereof.
[0374] In various embodiments, when the immune- stimulatory compound is a kinase inhibitor, the linker is covalently bound to the kinase inhibitor at a position on the kinase inhibitor that is at or near the solvent interface of the kinase active site when the inhibitor is bound to the protein target, as determined by modeling of the kinase inhibitor in the kinase active site. In certain embodiments, the linker is covalently bound to the kinase inhibitor at a position on the kinase inhibitor such that when the kinase inhibitor is bound to the active site, the linker extends out from the kinase active site into the solvent, as determined by modeling of the kinase inhibitor in the kinase active site.

In certain embodiments, the EC50 or IC50 of the immune- stimulatory compound-linker construct is no greater than 10-fold higher than the EC50 or IC50 of a control compound, wherein the control compound is the unbound immune- stimulatory compound. In an exemplary embodiment, the potency of the immune- stimulatory compound-linker construct is equivalent to or greater than the potency of a control compound, wherein the control compound is the unbound immune- stimulatory compound.
[0379] In some aspects, the present disclosure provides an immune- stimulatory conjugate comprising: (a) an immune- stimulatory compound that binds to a protein active site and stimulates an immune response through target inhibition (e.g., inhibition of a protein); (b) an antibody construct comprising an antigen binding domain and an Fc domain, wherein the antigen binding domain binds to a first antigen and wherein the Fc domain binds to an Fc receptor; and (c) a linker, wherein the linker is covalently bound to the antibody construct and the linker is covalently bound to the immune- stimulatory compound; wherein the Kd for binding of the immune- stimulatory compound of the conjugate to the protein active site is no greater than 100 times the Kd for binding of a control compound to the protein active site or wherein the IC50 of the immune- stimulatory compound of the conjugate is no greater than 300-fold the IC50 of a control compound, wherein the control compound is the unbound immune- stimulatory compound, and optionally wherein the Kd for binding of the Fc domain of the conjugate to an Fc receptor is no greater than about 100 times the Kd for binding of a control antibody to the Fc receptor, wherein the control antibody is the antibody construct itself.

Linkers
[0387] The immune- stimulatory compounds and salts thereof described herein may be attached, i.e., covalently attached, to a linker, e.g., a cleavable linker or a non-cleavable linker, and to an antibody construct and referred to as an immune- stimulatory compound conjugate, an immune- stimulatory conjugate or a conjugate. Linkers of the conjugates described herein may not affect the binding of active portions of a conjugate, e.g., the first binding domains, Fc domains, second antigen binding domains, antibodies, immune- stimulatory compounds or the like, to a target molecule, which can be a cognate binding partner such as an antigen. A conjugate can comprise multiple linkers. These linkers can be the same linkers or different linkers. A linker described herein can be a multi-functional linker linking two small molecule binding moieties and linking the linked small molecules to an antibody. A linker also may be referred to as a linker of a linker moiety.
[0388] A linker can be short, flexible, rigid, cleavable, non-cleavable, hydrophilic, or hydrophobic. A linker can contain segments that have different characteristics, such as segments of flexibility or segments of rigidity. The linker can be chemically stable to extracellular environments, for example, chemically stable in the blood stream, or may include linkages that are not stable. The linker can include linkages that are designed to cleave and/or immolate or otherwise breakdown specifically or non- specifically inside cells. A cleavable linker can be sensitive to enzymes. A cleavable linker can be cleaved by enzymes such as proteases. A cleavable linker can have a valine-citrulline or a valine- alanine dipeptide. A valine-citrulline- or valine-alanine-containing linker also can contain a pentafluorophenyl group. A valine-citrulline- or valine-alanine-containing linker also can contain a succinimide group or a maleimide group. A valine-citrulline- or valine-alanine-containing linker can also contain a para aminobenzoic acid (PABA) group. A valine-citrulline or valine- alanine (VA)-containing linker or a glycine-glycine- phenylalanine-glycine (GGFG) tetrapeptide-containing linker also can contain a PABA group and a pentafluorophenyl group. A peptide-based valine-citrulline or valine- alanine linker can contain a PABA group and a succinimide group. [0389] A non-cleavable linker is protease insensitive and insensitive to cleavage by other intracellular processes. A non-cleavable linker can be maleimidocaproyl linker. A
maleimidocaproyl linker can comprise N-maleimidomethylcyclohexane-l-carboxylate. A maleimidocaproyl linker can contain a succinimide group. A linker can be a combination of a maleimidocaproyl group and one or more polyethylene glycol molecules. A linker can be a maleimide-PEGx linker, where x = 2-12. A linker can be a combination of a maleimidocaproyl linker containing a succinimide group and one or more polyethylene glycol molecules. A linker can contain a maleimide(s) linked to polyethylene glycol molecules in which the polyethylene glycol can allow for more linker flexibility or can be used.
[0390] A linker can also include an alkylene, alkenylene, alkynylene, polyether, polyester, polyamide, polyamino acids, polypeptides, cleavable peptides, or amino benzylcarbamates. A linker can contain a maleimide at one end and an N-hydroxysuccinimidyl ester at the other end. A linker can contain a lysine with an N-terminal amine acetylated, and a valine-citrulline peptide cleavage site. A linker can be a link created by a microbial transglutaminase, wherein the link can be created between an amine-containing moiety and a moiety engineered to contain glutamine as a result of the enzyme catalyzing a bond formation between the acyl group of a glutamine side chain and the primary amine of a lysine chain. A linker can contain a reactive primary amine. A linker can be a Sortase A linker. A Sortase A linker can be created by a Sortase A enzyme fusing an LPXTG recognition motif (SEQ ID NO: 672) to an N-terminal GGG motif to regenerate a native amide bond. A linker created can therefore link a moiety attached to the LPXTG recognition motif (SEQ ID NO: 672) with a moiety attached to the N-terminal GGG motif.
[0391] In the conjugates described herein, an immune- stimulatory compound is linked to the antibody construct by way of a linker. The linker attaching the compound or a salt thereof to the antibody construct may be short, long, hydrophobic, hydrophilic, flexible or rigid, or may be composed of segments that each independently have one or more of the above-mentioned properties such that the linker may include segments having different properties. A linker may be polyvalent such that it covalently links more than one compound or salt to a single site on the antibody construct, or monovalent such that covalently it links a single compound or salt to a single site on the antibody construct.
[0392] As will be appreciated by skilled artisans, the linkers attach the immune- stimulatory compounds to the antibody construct by covalent linkages between the linker(s) and the antibody construct and compound. As used herein, the expression "linker" is intended to include (i) unconjugated forms of the linker that include a functional group capable of covalently linking the linker to an immune- stimulatory compound and a functional group capable of covalently linking the linker to an antibody; (ii) partially conjugated forms of the linker that include a functional group capable of covalently linking the linker to an antibody and that is covalently linked to an immune- stimulatory compound, or vice versa; and (iii) fully conjugated forms of the linker that is covalently linked to both an immune- stimulatory compound and an antibody.
[0393] Exemplary polyvalent linkers that may be used to link many immune- stimulatory compounds to an antibody construct are described. In some embodiments, the conjugate uses any linker as disclosed in U.S. Patent No. 9,254,339, U.S. Patent No. 9,144,615, U.S. Patent No. 8,821,850, U.S. Patent No. 8,808,679, U.S. Patent No. 8,685,383, U.S. Patent No. 8,524,214, or Published U.S. Publication No. 2011/0243892, in which each of these references are herein incorporated by reference in their entirety. For example, Fleximer® linker technology has the potential to enable high-DAR conjugates with good physicochemical properties. As shown below, the Fleximer® linker technology is based on incorporating drug molecules into a solubilizing poly-acetal backbone via a sequence of ester bonds. The methodology renders highly-loaded conjugates (DAR up to 20) whilst maintaining good physicochemical properties.

Figure imgf000220_0001
[0394] To utilize the Fleximer® linker technology depicted in the scheme above, an aliphatic alcohol can be present or introduced into the immune- stimulatory compound. The alcohol moiety is then attached to an alanine moiety, which is then synthetically incorporated into the Fleximer® linker. Liposomal processing of the conjugate in vitro releases the parent alcohol-containing drug.
[0395] Cleavable linkers can be cleavable in vitro and in vivo. Cleavable linkers can include chemically or enzymatically unstable or degradable linkages. Cleavable linkers can rely on processes inside the cell to liberate an immune- stimulatory compound, such as reduction in the cytoplasm, exposure to acidic conditions in the lysosome, or cleavage by specific proteases or other enzymes within the cell. Cleavable linkers can incorporate one or more chemical bonds that are either chemically or enzymatically cleavable while the remainder of the linker can be non- cleavable. [0396] A linker can contain a chemically labile group such as a hydrazone and/or disulfide group. Linkers comprising chemically labile groups can exploit differential properties between the plasma and some cytoplasmic compartments. The intracellular conditions that can facilitate immune- stimulatory compound release for hydrazone-containing linkers can be the acidic environment of endosomes and lysosomes, while the disulfide containing linkers can be reduced in the cytosol, which can contain high thiol concentrations, e.g., glutathione. The plasma stability of a linker containing a chemically labile group can be increased by introducing steric hindrance using substituents near the chemically labile group.
[0397] Acid-labile groups, such as hydrazone, can remain intact during systemic circulation in the blood's neutral pH environment (pH 7.3-7.5) and can undergo hydrolysis and can release the immune- stimulatory compound once the immune- stimulatory conjugate is internalized into mildly acidic endosomal (pH 5.0-6.5) and lysosomal (pH 4.5-5.0) compartments of the cell. This pH dependent release mechanism can be associated with nonspecific release of the compound. To increase the stability of the hydrazone group of the linker, the linker can be varied by chemical modification, e.g., substitution, allowing tuning to achieve more efficient release in the lysosome with a minimized loss in circulation.
[0398] Hydrazone-containing linkers can contain additional cleavage sites, such as additional acid-labile cleavage sites and/or enzymatically labile cleavage sites. Immune- stimulatory conjugates can include exemplary hydrazone-containing linkers can include, for example, the following structures:
Figure imgf000221_0001
wherein D is an immune- stimulatory compound, Ab is an antibody construct, -NH- or -S-
(connected to Ab) are part of the antibody construct, and n represents the number of compounds bound to linkers bound to the antibody construct. In certain linkers, such as linker (la), the linker can comprise two cleavable groups- a disulfide and a hydrazone moiety. For such linkers, effective release of the unmodified free immune- stimulatory compound can require acidic pH or disulfide reduction and acidic pH. Linkers such as (lb) and (Ic) can be effective with a single hydrazone cleavage site.
[0399] Other acid-labile groups that can be included in linkers include czs-aconityl-containing linkers, cis- Aconityl chemistry can use a carboxylic acid juxtaposed to an amide bond to accelerate amide hydrolysis under acidic conditions.
[0400] Cleavable linkers can also include a disulfide group. Disulfides can be
thermodynamically stable at physiological pH and can be designed to release the immune- stimulatory compound upon internalization inside cells, wherein the cytosol can provide a significantly more reducing environment compared to the extracellular environment. Scission of disulfide bonds can require the presence of a cytoplasmic thiol cofactor, such as (reduced) glutathione (GSH), such that disulfide-containing linkers can be reasonably stable in circulation, selectively releasing the immune- stimulatory compound in the cytosol. The intracellular enzyme protein disulfide isomerase, or similar enzymes capable of cleaving disulfide bonds, can also contribute to the preferential cleavage of disulfide bonds inside cells. GSH can be present in cells in the concentration range of 0.5-10 mM compared with a significantly lower concentration of GSH or cysteine, the most abundant low-molecular weight thiol, in circulation at approximately 5 μΜ. Tumor cells, where irregular blood flow can lead to a hypoxic state, can result in enhanced activity of reductive enzymes and therefore even higher glutathione concentrations. The in vivo stability of a disulfide-containing linker can be enhanced by chemical modification of the linker, e.g., use of steric hindrance adjacent to the disulfide bond.
[0401] Immune- stimulatory conjugates can include exemplary disulfide-containing linkers having the following structures:
Figure imgf000222_0001
wherein D is an immune- stimulatory compound, Ab is an antibody construct, -NH- or -S- (connected to Ab) are part of the antibody construct, n represents the number of compounds bound to linkers bound to the antibody construct and R is independently selected at each occurrence from hydrogen or Ci-ioalkyl, for example. Increasing steric hindrance adjacent to the disulfide bond can increase the stability of the linker. Structures such as (Ila) and (lie) can show increased in vivo stability when one or more R groups is selected from a lower alkyl such as methyl.
[0402] Another type of linker that can be used is a linker that is specifically cleaved by an enzyme. For example, the linker can be cleaved by a lysosomal enzyme. Such linkers can be peptide-based or can include peptidic regions that can act as substrates for enzymes. Peptide based linkers can be more stable in plasma and extracellular milieu than chemically labile linkers.
[0403] Peptide bonds can have good serum stability, as lysosomal proteolytic enzymes can have very low activity in blood due to endogenous inhibitors and the unfavorably high pH value of blood compared to lysosomes. Release of an immune- stimulatory compound from an antibody construct can occur due to the action of lysosomal proteases, e.g., cathepsin and plasmin. These proteases can be present at elevated levels in certain tumor tissues. The linker can be cleavable by a lysosomal enzyme. The lysosomal enzyme can be, for example, cathepsin B, β- glucuronidase, or β-galactosidase.
[0404] The peptide can be selected from tetrapeptides such as Gly-Phe-Leu-Gly, Ala- Leu- Ala- Leu, Gly-Gly-Phe-Gly or dipeptides such as Val-Cit, Val-Ala, and Phe-Lys. Dipeptides can have lower hydrophobicity compared to longer peptides, depending on amino acid composition. A peptide can also include non-natural amino acids or a mix of natural and non-natural amino acids.
[0405] A variety of dipeptide-based cleavable linkers can be used in the immune- stimulatory conjugates described herein.
[0406] Enzymatically cleavable linkers can include a self-immolative spacer to spatially separate the immune- stimulatory compound from the site of enzymatic cleavage. The direct attachment of an immune- stimulatory compound to a peptide linker can result in proteolytic release of an amino acid adduct of the immune- stimulatory compound, thereby impairing its activity. The use of a self-immolative spacer can allow for the elimination of the fully active, chemically unmodified immune- stimulatory compound upon amide bond hydrolysis.
[0407] One self-immolative spacer can be a bifunctional /?ara-aminobenzyl alcohol group, which can link to the peptide through an amino group of the immune- stimulatory compound, forming an amide bond, while amine containing immune- stimulatory compounds can be attached through carbamate functionalities to the benzylic hydroxyl group of the linker (to give a p- amidobenzylcarbamate, PABC). The resulting pro-immune-stimulatory compound can be activated upon protease-mediated cleavage, leading to a 1,6-elimination reaction releasing the unmodified immune- stimulatory compound, carbon dioxide, and remnants of the linker. The following scheme depicts the fragmentation of p- amidobenzyl carbamate and release of the immune- stimulator compound:
Figure imgf000224_0001
X-D
wherein X-D represents the unmodified immune- stimulatory compound. Heterocyclic variants of this self-immolative group have also been described.
[0408] The enzymatically cleavable linker can be a B-glucuronic acid-based linker. Facile release of the immune- stimulatory compound can be realized through cleavage of the B-glucuronide glycosidic bond by the lysosomal enzyme B-glucuronidase. This enzyme can be abundantly present within lysosomes and can be overexpressed in some tumor types, while the enzyme activity outside cells can be low. B-Glucuronic acid-based linkers can be used to circumvent the tendency of an immune- stimulatory conjugate to undergo aggregation due to the hydrophilic nature of B-glucuronides. In certain embodiments, B-glucuronic acid-based linkers can link an antibody construct to a hydrophobic immune- stimulatory compound. The following scheme depicts the release of an immune- stimulatory compound (D) from an immune- stimulatory con ugate containing a B-glucuronic acid-based linker and an antibody construct (Ab):
Figure imgf000224_0002
[0409] A variety of cleavable β-glucuronic acid-based linkers useful for linking drugs such as auristatins, camptothecin and doxorubicin analogues, CBI minor-groove binders, and psymberin to antibodies have been described. These β-glucuronic acid-based linkers may be used in the conjugates described herein. In certain embodiments, the enzymatically cleavable linker is a β- galacto side-based linker. β-Galactoside is present abundantly within lysosomes, while the enzyme activity outside cells is low.
[0410] Additionally, immune- stimulatory compounds containing a phenol group can be covalently bonded to a linker through the phenolic oxygen. One such linker relies on a methodology in which a diamino-ethane "Space Link" is used in conjunction with traditional "PABO" -based self-immolative groups to deliver phenols. Methylene carbamate linkers have also been described that allow linkages to hydroxyl groups on compounds.
[0411] Immune- stimulatory compounds containing a tertiary amine can be covalently bond to a linker to the tertiary amine by creating a quaternary amine linkage.
[0412] Cleavable linkers can include non-cleavable portions or segments, and/or cleavable segments or portions can be included in an otherwise non-cleavable linker to render it cleavable. By way of example only, polyethylene glycol (PEG) and related polymers can include cleavable groups in the polymer backbone. For example, a polyethylene glycol or polymer linker can include one or more cleavable groups such as a disulfide, a hydrazone or a dipeptide.
[0413] Other degradable linkages that can be included in linkers can include ester linkages formed by the reaction of PEG carboxylic acids or activated PEG carboxylic acids with alcohol groups on an immune- stimulatory compound, wherein such ester groups can hydrolyze under physiological conditions to release the immune- stimulatory compound. Hydrolytically degradable linkages can include, but are not limited to, carbonate linkages; imine linkages resulting from reaction of an amine and an aldehyde; phosphate ester linkages formed by reacting an alcohol with a phosphate group; acetal linkages that are the reaction product of an aldehyde and an alcohol; orthoester linkages that are the reaction product of a formate and an alcohol; and oligonucleotide linkages formed by a phosphoramidite group, including but not limited to, at the end of a polymer, and a 5' hydroxyl group of an oligonucleotide.
[0414] A linker can contain an enzymatically cleavable peptide moiety, for example, a linker comprising structural formula (Ilia), (Mb), (IIIc), or (Hid):

Figure imgf000226_0001

In particular embodiments, the dipeptide can be selected from: Val-Cit; Cit-Val; Ala- Ala; Ala-Cit; Cit-Ala; Asn-Cit; Cit-Asn; Cit-Cit; Val-Glu; Glu-Val; Ser-Cit; Cit-Ser; Lys-Cit; Cit-Lys; Asp-Cit; Cit-Asp; Ala-Val; Val-Ala; Phe-Lys; Lys-Phe; Val-Lys; Lys-Val; Ala-Lys; Lys-Ala; Phe-Cit; Cit-Phe; Leu- Cit; Cit-Leu; Ile-Cit; Cit-Ile; Phe-Arg; Arg-Phe; Cit-Trp; and Trp-Cit, or salts thereof.
[0416] In certain embodiments, the peptide can be selected from a di-peptide or tri-peptide of non-natural amino acids, a mixture of natural and non-natural amino acids, amino acid analogs or a mixture of amino acids and amino acid analogs.

[0425] Although cleavable linkers can provide certain advantages, the linkers comprising the conjugate described herein need not be cleavable. For non-cleavable linkers, the immune- stimulatory compound release may not depend on the differential properties between the plasma and some cytoplasmic compartments. The release of an active form of the immune- stimulatory compound can occur after internalization of the immune- stimulatory conjugate via antigen- mediated endocytosis and delivery to lysosomal compartment, where the antibody construct can be degraded to the level of amino acids through intracellular proteolytic degradation. This process can release an immune- stimulatory compound derivative, which is formed by the immune- stimulatory compound, the linker, and the amino acid residue to which the linker was covalently attached (e.g., a cysteine residue). The immune- stimulatory compound derivative from immune- stimulatory conjugates with non-cleavable linkers can be more hydrophilic and less membrane permeable, which can lead to less bystander effects and less nonspecific toxicities compared to immune- stimulatory conjugates with a cleavable linker. Immune- stimulatory conjugates with non-cleavable linkers can have greater stability in circulation than immune- stimulatory conjugates with cleavable linkers. Non-cleavable linkers can be alkylene chains, or can be polymeric, such as, for example, based upon polyalkylene glycol polymers, amide polymers, or can include segments of alkylene chains, polyalkylene glycols and/or amide polymers. The linker can contain a polyethylene glycol segment having from 1 to 6 ethylene glycol units.
[0426] The linker can be non-cleavable in vivo, for example, a linker according to the
formulations below:
Figure imgf000245_0001
thereof, wherein: R is selected from hydrogen, Ci-ioalkyl, sulfonate and methyl sulfonate; Rx is a moiety including a functional group capable of covalently linking the linker to an antibody construct; and ^ represents the point of attachment of the linker to an immune- stimulatory compound.
[0427] Exemplary embodiments of linkers according to structural formula (Va)-(Ve) that may be included in the conjugates described herein include the linkers illustrated below (as illustrated, the linkers include a group suitable for covalently linking the linker to an antibody construct, and represents the point of attachment to an immune- stimulatory compound):
0428]
Figure imgf000245_0002
Figure imgf000246_0001
[0429] Attachment groups (also referred to as reactive groups herein) that are used to attach the linkers to an antibody construct can be electrophilic in nature and include, for example, maleimide groups, activated disulfides, active esters such as NHS esters and HOBt esters, haloformates, acid halides, alkyl, and benzyl halides such as haloacetamides. There are also emerging technologies related to "self- stabilizing" maleimides and "bridging disulfides" that can be used in accordance with the disclosure.
[0430] One example of a "self- stabilizing" maleimide group that hydrolyzes spontaneously under conjugation conditions to give a conjugate species with improved stability is depicted in the schematic below. Thus, the maleimide attachment group is reacted with a sulfhydryl of an antibody to give an intermediate succinimide ring, after which the succinmide ring hydrolizes opens to form a ring opened form. The hydro lyzed form of the attachment group is resistant to deconjugation in the presence of plasma proteins.

[0431] A method for bridging a pair of sulfhydryl groups derived from reduction of a native hinge disulfide bond has been disclosed and is depicted in the schematic below. An advantage of this methodology is the ability to synthesize homogenous DAR4 conjugates by full reduction of
IgGls (to give 4 pairs of reactive sulfhydryls) followed by reaction with 4 equivalents of the alkylating agent. Conjugates containing "bridged disulfides" are also claimed to have increased stability.

[0432] Similarly, as depicted below, a maleimide derivative that is capable of bridging a pair of sulfhydryl groups has been developed.

[0434] Exemplary embodiments of linkers according to structural formulae (Via) and (VIb) that can be included in the conjugates described herein can include the linkers illustrated below (as illustrated, the linkers can include a group suitable for covalently linking the linker to an antibody construct):

[0435] Exemplary embodiments of linkers according to structural formula (Vic) that can be included in the immune- stimulatory conjugates described herein can include the linkers illustrated below (as illustrated, the linkers can include a group suitable for covalently linking the linker to an antibod construct):
Figure imgf000252_0002
Figure imgf000253_0001
wherein the wavy line indicates a point of attachment to the immune- stimulatory compound.
[0436] As is known by skilled artisans, the linker selected for a particular immune- stimulatory conjugate may be influenced by a variety of factors, including but not limited to, the site of attachment to the antibody construct (e.g., lysine, cysteine, glutamine, glutamate or other amino acid residue(s)), structural constraints of the drug pharmacophore and the lipophilicity of the drug. The specific linker selected for a conjugate should seek to balance these different factors for the specific antibody construct/immune stimulatory compound combination.
[0437] For example, ADCs with cytotoxic agents have been observed to effect killing of bystander antigen-negative cells present in the vicinity of the antigen-positive tumor cells. The mechanism of bystander cell killing by ADCs has indicated that metabolic products formed during intracellular processing of the ADCs may play a role. Neutral and/or hydrophobic cytotoxic metabolites generated by metabolism of the ADCs in antigen-positive cells appear to play a role in bystander cell killing while charged or hydrophilic metabolites may be prevented from diffusing across the membrane into the medium and therefore cannot affect bystander killing. In certain embodiments as described herein, the linker for an immune- stimulatory conjugate is selected to attenuate the bystander effect caused by cellular metabolites of the conjugate. In certain embodiments, the linker is selected to increase the bystander effect.
[0438] The properties of the linker may also affect aggregation of the conjugate under conditions of use and/or storage. Typically, ADCs reported in the literature contain no more than 3-4 drug molecules per antibody molecule. Attempts to obtain higher drug-to-antibody ratios ("DAR") often failed, particularly if both the drug and the linker were hydrophobic, due to aggregation of the ADC. In many instances, DARs higher than 3-4 could be beneficial as a means of increasing potency. In instances where the drug is hydrophobic in nature, it may be desirable to select linkers that are relatively hydrophilic as a means of reducing aggregation, especially in instances where DARs greater than 3-4 are desired. Thus, in certain embodiments, the linker of an immune- stimulatory conjugate incorporates chemical moieties that reduce aggregation of the conjugate during storage and/or use. A linker may incorporate polar or hydrophilic groups such as charged groups or groups that become charged under physiological pH to reduce the aggregation of the conjugate. For example, a linker may incorporate charged groups such as salts or groups that deprotonate, e.g., carboxylates, or protonate, e.g., amines, at physiological pH.
[0439] In particular embodiments, the aggregation of the conjugates during storage or use is less than about 40% as determined by size-exclusion chromatography (SEC). In particular
embodiments, the aggregation of the conjugates during storage or use is less than 35%, such as less than about 30%, such as less than about 25%, such as less than about 20%, such as less than about 15%, such as less than about 10%, such as less than about 5%, such as less than about 4%, or even less, as determined by size-exclusion chromatography (SEC).
General method for interchain cysteine-based bioconjugations
[0440] An antibody construct can be conjugated to a linker via cysteine-based bioconjugation.
An antibody construct can be exchanged into an appropriate buffer, for example, phosphate, borate, PBS, histidine, Tris-Acetate at a concentration of about 2 mg/mL to about 10 mg/mL with an appropriate number of equivalents of a reducing agent, for example, dithiothreitol or tris(2- carboxyethyl)phosphine. The resultant solution can be stirred for an appropriate amount of time and temperature to effect the desired reduction. A construct of an amino-pyrazinecarboxamide compound and a linker can be added as a solution with stirring. Dependent on the physical properties of the linker-pay load, a co-solvent can be introduced prior to the addition of the linker- payload to facilitate solubility. The reaction can be stirred at room temperature for about 1 hour to about 12 hours depending on the observed reactivity. The progression of the reaction can be monitored by liquid chromatography-mass spectrometry (LC-MS). Once the reaction is deemed complete, the remaining free linker-pay load can be removed by applicable methods and the antibody conjugate can be exchanged into the desired formulation buffer. Such cysteine-based conjugates can be synthesized starting with an antibody (rnAb) and linker-payload, e.g., 7 equivalents, using the conditions described in Scheme A below (Conjugate = antibody conjugate). Monomer content and drug-antibody ratios can be determined by methods described herein.

[0442] The conjugates described herein may also comprise antibody constructs and constructs having immune-modulatory activity through targeted degradation of proteins. As used herein, such conjugates are termed immune-modulatory conjugates and have a direct or indirect effect on the immune system. In some embodiments, the conjugates can target proteins involved in immune activation, inhibition or regulation. In some embodiments, the conjugates can target proteins in tumor cells and cause cell death or apoptois and indirectly stimulate the immune system. In various embodiments, proteolysis targeting modules (PTM) are attached (e.g., conjugated) through a linker to an antibody construct to form immune-modulatory conjugates.
[0443] In certain embodiments, an immune-modulatory conjugate comprises an antibody construct, a linker, and two binding moieties. The linker can be a multifunctional linker (W) that can covalently attach two binding moieties (X and Y) to form a proteolysis targeting module (X- W-Y) designed to induce degradation of a protein target. A PTM can comprise a first binding moiety (X) that can bind to a protein target (the moiety also referred to as a target protein binding moiety or protein targeting moiety) and a second binding moiety (Y) that can bind to an E3 ubiquitin ligase. The multi-functional linker also can covalently attach the PTM to a residue(s) (e.g., lysine, cysteine or engineered residue) on an antibody construct (Z) (e.g., an antibody) to form an immune-modulatory conjugate, as shown below:

[0444] In some aspects, an immune-modulatory conjugate comprises a proteolysis targeting module that can bind to a protein active site and can stimulate an immune response through protein target degradation; an antibody construct comprising an antigen binding domain and an Fc domain, wherein the antigen binding domain can bind to a first antigen; and a multifunctional linker, wherein the linker is covalently bound to the antibody construct and to protein targeting moiety (a first binding moiety) and an E3 ubiquitin ligase binding moiety (second binding moiety). In some embodiments, the Fc domain is an Fc null. In some embodiments, the Fc domain is a wild-type IgG that can bind to Fey receptors. In some embodiments, the Fc domain can bind to an Fc receptor, wherein the IQ for binding of the Fc domain of the conjugate to an Fc receptor is no greater than about 100 times the Kd for binding of a control antibody construct to the Fc receptor, wherein the control antibody construct is the unconjugated antibody construct. In some embodiments, the Kd for binding of the first binding moiety of the conjugate to the protein active site is no greater than 100 times the Kd for binding of a control compound to the protein active site or wherein the IC50 of the first binding moiety of the conjugate is no greater than 300-fold the IC50 of a control compound, wherein the control compound is the free first binding moiety. In some embodiments, the proteolysis targeting module can be comprised of: a) a small molecule that can bind a protein target, degredation or inhibition of which is immune stimulatory, b) a multi-functional linker that can be covalently bonded to elements a) and c); and c) a small molecule that can bind to an E3 ubiquitin ligase.
[0445] In some embodiments, the proteolysis targeting module can be comprised of a) a small molecule that can bind to a protein target, inhibition or degredation of which is immune stimulatory, b) a multi-functional linker that can be covalently bonded to elements a) and c); and c) a small molecule that can bind an E3 ubiquitin ligase, wherein the proteolysis targeting module can increase degradation of the protein target within a cell.

The PTM is attached to the antibody construct via another linker, as further described below.
[0447] In other embodiments, the proteolysis targeting module can be comprised of a) a first binding moiety that can bind to an immune stimulatory target, b) a second linker that can attach the first binding moiety to element c), and c) a compound that can bind to an E3 ubiquitin ligase, wherein the PTM can increase degradation of the immune- stimulatory target in cells expressing antigen of the first binding domain or second binding domain of the conjugate (containing the PTM) compared to degradation of the immune- stimulatory target in cells not expressing, or expressing lower levels of, antigen of the first binding domain or second binding domain of the conjugate.
[0448] These conjugates can be made by various methods. It is understood that one skilled in the art may be able to make these compounds by similar methods or by combining other methods known to one skilled in the art. It is also understood that one skilled in the art would be able to make, in a similar manner as described herein by using the appropriate starting materials and modifying the synthetic route as needed.

A linker can be a link created between an unnatural amino acid on a construct by reacting with oxime bond that was formed by modifying a ketone group with an alkoxyamine on an immune- stimulatory compound. The immune- stimulatory compound can comprise one or more rings selected from carbocyclic and heterocyclic rings. The immune- stimulatory compound can be covalently bound to a linker by a bond to an exocyclic carbon or nitrogen atom on the immune- stimulatory compound. A linker can be attached to an immune- stimulatory compound via an exocyclic nitrogen or carbon atom of an immune- stimulatory compound. The Kd for binding of a binding domain of any of these conjugates to its antigen can be about 2 times, about 3 times, about 4 times, about 5 times, about 6 times, about 7 times, about 8 times, about 9 times, about 10 times, about 15 times, about 20 times, about 25 times, about 30 times, about 35 times, about 40 times, about 45 times, about 50 times, about 60 times, about 70 times, about 80 times, about 90 times, about 100 times, about 110 times, or about 120 times greater than the Kd for binding of the binding domain to its antigen in the absence of the immune- stimulatory compound. The Kd for binding of the binding domain of any of these conjugates to its antigen can be less than 10 nM. The Kd for binding of the binding domain of any of the conjugates to its antigen can be less than 100 nM, less than 50 nM, less than 20 nM, less than 5 nM, less than 1 nM, or less than 0.1 nM. The Kd for binding of the Fc domain of any of the conjugates to an Fc receptor can be about 2 times, about 3 times, about 4 times, about 5 times, about 6 times, about 7 times, about 8 times, about 9 times, about 10 times, about 15 times, about 20 times, about 25 times, about 30 times, about 35 times, about 40 times, about 45 times, about 50 times, about 60 times, about 70 times, about 80 times, about 90 times, about 100 times, about 110 times, or about 120 times greater than the Kd for binding of the Fc domain to the Fc receptor in the absence of the immune- stimulatory compound. The Kd for binding of the Fc domain of any of the conjugates to an Fc receptor can be less than 10 nM. The Kd for binding of the Fc domain of any of the conjugates to an Fc receptor can be less than 100 nM, less than 50 nM, less than 20 nM, less than 5 nM, less than 1 nM, or less than 0.1 nM.
[0517] In some embodiments, in a conjugate, an antibody can be linked to an immune- stimulatory compound in such a way that the antibody construct, such as an antibody, can still bind to an antigen and the Fc domain of the antibody construct, can still bind to an FcR. In a conjugate, an antibody construct is linked to an immune- stimulatory compound in such a way that the linking does not interfere with ability of the antigen binding domain of the antibody construct to bind to antigen, the ability of the Fc domain of the antibody construct to bind to an FcR, or FcR-mediated signaling resulting from the Fc domain of the antibody construct from binding to an FcR. In a conjugate, an immune- stimulatory compound can be linked to an antibody construct in such a way the linking does not interfere with the ability of the immune- stimulatory compound to bind to its receptor. A conjugate can produce stronger immune stimulation and a greater therapeutic window than components of the conjugate alone.

Any one of the additional administrations can be administered to the subject in need thereof every 21 days, every 14 days, every 10 days, every 7 days, every 4 days or every day after the first administration over the course of a cycle. The additional administrations can also be administered to the subject in need thereof less than 21 days, or less than 14 days, less than 10 days, less than 7 days, less than 4 days, or less than 1 day after the first administration. The one or more administrations can occur more than once per day, more than once per week or more than once per month. Cycles of administration of a
pharmaceutical composition can be weekly, biweekly, every three weeks, monthly, every six weeks, every two months, or the like.
[0540] Suitable doses of an immune- stimulatory conjugate with a DAR of 1-8 can be from about 0.05 mg/kg to about 20 mg/kg or about 0.5 mg/kg to about 20 mg/kg, or about 1 mg/kg to about 10 mg/kg. Doses of conjugates with greater DARs can be scaled accordingly.
Increased dosages and reduced side-effects
[0541] In certain embodiments, the conjugates can comprise two binding domains, one of which binds to a tumor antigen and another of which binds to a target on an immune cell such as an antigen presenting cell and can be administered in a dosage that is about 10%, about 25%, about 50%, about 100% or greater than an antibody from which one of the tumor antigen binding domains or binding domains that bind to an antigen on an immune cell, such as an antigen presenting cell (APC), is derived. For example, a common regimen for administering pertuzumab comprises 840 mg intravenous (IV) administered as an initial dose over 60 minutes, followed every 3 weeks thereafter by 420 mg IV over 30 to 60 minutes. An initial dosage of a conjugate having a binding domain of pertuzumab and a second binding domain binding to an immune cell antigen can range from 900 mg to 1700 mg or more and a maintenance dose can range from 450 mg to 900 mg or more. An increased initial dose and/or maintenance dose can be used with an immune stimulatory conjugate or pharmaceutical composition of this disclosure, such as bispecific tumor targeting compositions comprising a tumor antigen binding domain that binds a tumor antigen with at least 80% or 100% sequence identity to CD5, CD19, CD20, CD25, CD37, CD30, CD33, CD45, CAMPATH-1, BCMA, CS-1, PD-L1, B7-H3, B7-DC (PD-L2), HLD-DR, carcinoembryonic antigen (CEA), TAG-72, EpCAM, MUC1, MUC15, MUC16, fo late-binding protein, A33, G250, pro state- specific membrane antigen (PSMA), ferritin, GD2, GD3, GM2, Ley, CA-125, CA19-9, epidermal growth factor, pl85HER2, IL-2 receptor, EGFRvIII (de2-7 EGFR), fibroblast activation protein (FAP), tenascin, a metalloproteinase, endosialin, vascular endothelial growth factor, ανβ3, WT1, LMP2, HPV E6 E7, Her-2/neu, p53 nonmutant, NY-ESO-1,

[0542] In certain embodiments, using an immune- stimulatory conjugate of this disclosure can allow administration of a conjugate that comprises a binding domain that binds to an antigen on an antigen presenting cell at greater levels than an antibody alone comprising a binding domain that binds to that molecule on an antigen presenting cell. In certain embodiments, a bispecific immune- stimulatory conjugate that comprises a binding domain that binds to an antigen on an antigen presenting cell can be administered at levels equivalent to that of an antibody from which the binding domain is derived.
[0543] In certain embodiments, the immune- stimulatory conjugate can be administered at a dose higher than the maximum tolerated dose for that immune- stimulatory compound administered in the absence of attachment to an antibody construct.
[0544] In certain embodiments, administration of an immune stimulatory conjugate can be associated with fewer side effects than an antibody from which one of binding domains is derived. In certain embodiments, administration of the immune stimulatory conjugate can be associated with fewer side effects than when the immune- stimulatory compound is administered alone. In certain embodiments, administration of immune- stimulatory conjugate with a chemotherapeutic agent can be associated with fewer side effects than when the
chemotherapeutic agent is administered with the immune- stimulatory compound. In certain embodiments, the chemotherapeutic agent can be an alkylating agent (e.g., cyclophosphamide, ifosfamide, chlorambucil, busulfan, melphalan, mechlorethamine, uramustine, thiotepa, nitrosoureas, or temozolomide), an anthracycline (e.g., doxorubicin, adriamycin, daunorubicin, epirubicin, or mitoxantrone), a cytoskeletal disruptor (e.g., paclitaxel or docetaxel), a histone deacetylase inhibitor (e.g., vorinostat or romidepsin), an inhibitor of topoisomerase (e.g., irinotecan, topotecan, amsacrine, etoposide, or teniposide), a kinase inhibitor (e.g., bortezomib, erlotinib, gefitinib, imatinib, vemurafenib, or vismodegib), a nucleoside analog or precursor analog (e.g., azacitidine, azathioprine, capecitabine, cytarabine, fluorouracil, gemcitabine, hydroxyurea, mercaptopurine, methotrexate, or thioguanine), a peptide antibiotic (e.g., actinomycin or bleomycin), a platinum-based agent (e.g., cisplatin, oxaloplatin, or carboplatin), or a plant alkaloid (e.g., vincristine, vinblastine, vinorelbine, vindesine, podophyllotoxin, paclitaxel, or docetaxel). In some embodiments, the chemotherapeutic agent can be a nucleoside analog. In some embodiments, the chemotherapeutic agent can be gemcitabine. In certain embodiments, the additional therapeutic agent can be radiation therapy.

Plasmid expressing HER2 was transfected into HEK293 cells, and the cells were treated with DMSO, PROTAC T-20, HER2 antibody (IgGl), or Her2 Antibody-Protac conjugate (050-T11020). Whole cell lysates were prepared from cells after 2 (left blot), 24 (middle blot), or 48 (right blot) hours incubation and quantitated with a BCA assay. Equal amounts of lysates were run on protein gels, transferred to PVDF, and TGFPR2 (top), TGFpRl (middle), or control actin (bottom) was detected using commercially available reagents. At both tested concentrations of the conjugate, the level of target TGFPR2 was diminished at 24 and 48 hours of treatment as demonstrated by the diminished signal of TGFPR2 in the lanes containing 050-T11020. For the 2 hour blot, from left to right, the lanes represent DMSO; T-20 5 μΜ; 050 IgG 1 μΜ; 050-T11020 1 μΜ; and 050-T11020 0.5 μΜ. For the 24 hour blot, from left to right, the lanes represent DMSO; T-20 5 μΜ; 050 IgG 0.5 μΜ; 050 IgG 1 μΜ; 050-T11020 0.5 μΜ; and 050-T11020 1 μΜ.

A thick black line denotes 100 precent. The medium-gray bars at the left of each data set represent the data obtained at 2 hours of treatment. The darkest gray bars in the middle of each data set represent the data obtained at 24 hours. The lightest gray bars at the right of each data set represent the data obtained at 48 hours.

[0598] FIGURE 21C provides a quantification of the western blot data for TGFpRl shown in FIGURE 21 A. To quantitate the amount of protein degradation, the signals on the Western blot were adjusted to actin loading control and data was presented as a percent of matched control on the y-axis, which is labeled as 0 to 200 in intervals of 20. The medium-gray bars at the left of each data set represent the data obtained at 2 hours of treatment. The darkest gray bars in the middle of each data set represent the data obtained at 24 hours. The lightest gray bars on the right of each data set represent the data obtained at 48 hours. On the x-axis, from the left to right, the data sets are T20 5 μΜ; 050-11020 0.5 μΜ; and 050-11020 1 μΜ. Consistent with the western blot data, the amount of TGFpRl protein remained fairly constant throughout the treatment period.
[0599] FIGURE 22A and FIGURE 22B show the results of an assay for antigen targeted degradation of TGFPR2 by an antibody conjugate with PROTACs having VHL or Cereblon E3 binding moieties. BT474 cells were plated and treated the following day with either a T-15 PROTAC or a T-20 PROTAC, a conjugate of a HER2 antibody TGFpR2-VHL binding
PROTAC (050-T05020), a conjugate of a HER2 antibody TGFpR2-Cereblon binding PROTAC (050-T05015), or a conjugate of a TROP2 antibody TGFpR2-VHL binding PROTAC (130- T05020). Whole cell lysates were prepared 24 hours after treatment and quantitated with a BCA assay. Equal amounts of lysates were run on protein gels, transferred to PVDF, and TGFPR2 and actin were detected using commercially available reagents. FIGUGRE 22A shows that HER2- antigen specific degradation was found with both the HER2 binding PROTAC conjugates, but not with the control TROP2-binding PROTAC conjugate, as indicated by the retained signal of the TGFPR2 protein (top blot; actin control is bottom blot). The lanes, from left to right, represent DMSO; T-15 300 nM; T-20 300 nM; PBS; unlabeled; 050-T05015 0.5 mM; 050- T05020 0.5 μΜ; and 130-T05020 0.5 μΜ.
[0600] FIGURE 22B provides a quantitation of FIGURE 22A, and was determined by normalizing the TGFPR2 signals to actin loading control. The data are presented as a percent of vehicle control on the y-axis, which is labeled as 0 to 120 in intervals of 20. The x-axis, from left to right, represents T-15 300 nM; T-20 300 nM; 050-T05015; 050-T0520; and 130-T05020. The thick black line is at 100 of the y-axis.
[0601] FIGURE 23A and FIGURE 23B show the results of an assay for cellular levels of TGFpR2 and TGFpRl in the presence of a TGFpR2/TGFpRl-VHL PROTAC (T-20) with or without the addition of a proteasome inhibitor. Normal human lung fibroblasts were treated with or without proteasome inhibitor MG-132 followed by the addition of DMSO or T-20. Whole cell lysates were prepared and then quantitated with a BCA assay. Equal amounts of lysates were run on protein gels and transferred to PVDF membrane. TGFpRl, TGFPR2, and actin were detected using commercially available reagents. FIGURE 23A provides the western blot results of the assay. The results demonstrate that the addition of the proteasome inhibitor protected TGFpRl and TGFPR2 against degradation induced by T-20, as indicated by rescue of the TGFPR2 and TGFpR2 signals by addition of MG-132 in the presence of T-20. TGFpR2 is the top row, TGFpRl is the middle row, and actin is the bottom row. The left blots lanes represent, from left to right, MG132 concentrations of 0 (shown as -); 10; and 50 followed by addition of DMSO. The right blots represent, from left to right, MG132 concentrations of 0 (shown as -); 10; and 50 μΜ followed by addition of 5 μΜ T-20.
[0602] FIGURE 23B provides quantification of the results of the FIGURE 23A, and was obtained by adjusting the western signal to the actin loading control. The data are presented as a percent of the matched vehicle control on the y-axis, which is labeled from 0 to 100 at intervals of 10. The light gray bars represent the data for TGFPR2 and the dark gray bars represent the data for TGFpRl. The x-axis, from left to right, is labeled as T-20; T-20 + 10 μΜ MG132; and T-20 + 50 μΜ MG132.

[0630] The mAb (3-8 mg/mL in PBS) was exchanged into HEPES (100 mM, pH 7.0, 1 mM DTP A) via molecular weight cut-off centrifugal filtration (Millipore, 30 kDa). The resultant mAb solution was transferred to a tared 50 mL conical tube. The mAb concentration was determined to be 3-8 mg/mL by A28o. To the mAb solution was added TCEP (2.0-4.0 equivalents, 1 mM stock) at room temperature and the resultant mixture was incubated at 37 °C for 30-90 minutes, with gentle shaking. Upon being cooled to room temperature, a stir bar was added to the reaction tube. With stirring, the linker-pay load from Examples 1 and 2 (5-10 equivalents, 10 mM DMSO) was added dropwise. The resultant reaction mixture was allowed to stir at ambient temperature for 30-60 minutes, at which point N-ethyl maleimide (3.0 equivalents, 100 mM DMA) was added. After an additional 15 minutes of stirring, N-acetylcysteine (6.0-11.0 equivalents, 50 mM HEPES) was added. The crude ADC was then exchanged into PBS and purified by preparative SEC (e.g. HiLoad 26/600, Superdex 200pg) using PBS as the mobile phase. The pure fractions were concentrated via molecular weight cut-off centrifugal filtration (Millipore, 30 kDa), sterile filtered, and transferred to 15 mL conical tubes. Drug-antibody construct ratios (molar ratios) were determined by methods described in Example 4 below.

General Procedure for the Determination of the Drug- Antibody-Ratios [0631] Hydrophobic Interaction Chromatography
[0632] 10 μL· oΐ a 6 mg/mL solution of a conjugate is injected into an HPLC system set-up with a TOSOH TSKgel Butyl-NPR™ hydrophobic interaction chromatography (HIC) column (2.5 μΜ particle size, 4.6 mm x 35 mm) attached. Then, over the course of 18 minutes, a method is run in which the mobile phase gradient is run from 100% mobile phase A to 100% mobile phase B over the course of 12 minutes, followed by a six-minute re-equilibration at 100% mobile phase A. The flow rate is 0.8 mL/min and the detector is set at 280 nM. Mobile phase A is 1.5 M ammonium sulfate, 25 mM sodium phosphate (pH 7). Mobile phase B is 25% isopropanol in 25 mM sodium phosphate (pH 7). Post-run, the chromatogram is integrated and the molar ratio is determined by summing the weighted peak area.
Mass Spectrometry
One microgram of immune- stimulatory conjugate (antibody construct immune- stimulatory compound conjugate) is injected into an LC/MS such as an Agilent 6550 iFunnel Q-TOF equipped with an Agilent Dual Jet Stream ESI source coupled with Agilent 1290 Infinity UHPLC system. Raw data is obtained and is deconvoluted with software such as Agilent MassHunter Qualitative Analysis Software with BioConfirm using the Maximum Entropy deconvolution algorithm. The average mass of the conjugates is calculated by the software, which used top peak height at 25% for the calculation. This data is then imported into another program to calculate the molar ratio of the conjugates such as Agilent molar ratio calculator

Briefly, carboxymethylated dextran biosensor chips (CM5, BIACORE, Inc.) are activated with N-ethyl-N'-(3-dimethylaminopropyl)-carbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS) according to the supplier's instructions. Antigen is diluted with 10 mM sodium acetate, pH 4.8, to 5 μg/mL (~0.2 μΜ) before injection at a flow rate of 5 μΕ/ητίηυίε to achieve approximately 10 response units (RU) of coupled protein. Following the injection of antigen, 1 M ethanolamine is injected to block unreacted groups. For kinetics measurements, two-fold serial dilutions of Fab (0.78 nM to 500 nM) are injected in PBS with 0.05% polysorbate 20 (TWEEN-20™) surfactant (PBST) at 25 °C at a flow rate of approximately 25 μΕ/ηιίη. Association rates (kon) and dissociation rates (koff) are calculated using a simple one-to-one Langmuir binding model (BIACORE® Evaluation Software version 3.2) by simultaneously fitting the association and dissociation sensorgrams. The equilibrium dissociation constant (IQ) is calculated as the ratio k0ff/kon. See, e.g., Chen et al., J. Mol. Biol. 293:865-881 (1999). If the on-rate exceeds 106 M- l s- 1 by the surface plasmon resonance assay above, then the on-rate can be determined by using a fluorescent quenching technique that measures the increase or decrease in fluorescence emission intensity (excitation=295 nm; emission=340 nm, 16 nm band-pass) at 25 °C of a 20 nM anti-antigen antibody (Fab form) in PBS, pH 7.2, in the presence of increasing concentrations of antigen as measured in a spectrometer, such as a stop- flow equipped spectrophometer (Aviv Instruments) or a 8000-series SLM-AMINCO™
spectrophotometer (ThermoSpectronic) with a stirred cuvette.

EXAMPLE 8
General Procedure for measuring the Kd of kinase inhibitor by BLI
[0636] Measurement of the Kd for a kinase target is determined using the following reactants: (1) immune- stimulatory conjugate, (2) non-conjugated immune- stimulatory compound-linker constructs, and (3) non-conjugated immune- stimulatory control compound is performed using an Octet Red 96 instrument (ForteBio) with a biotin coated biosensor chip. As a negative control and baseline setting for the conjugate, the unconjugated control antibody is also included as a binding reactant (4). Purified, active, recombinant strep-tagged protein kinase domain is immobilized onto the bio-sensor surface at several concentrations. The analysis for each reactant is performed in the following steps: (1) baseline acquisition (60 s); (2) loading of the kinase domain onto the biotin coated biosensor (120 s); (3) second baseline acquisition (60 s); (4) association of the reactant (120 s); and (5) dissociation of reactant (480-900 s). The control reactant (1) is used at 6 concentrations of 3-fold concentration series diluted from a DMSO stock into PBS buffer for incubations. Data are analyzed using Octet Data Analysis Software 9.0 (ForteBio) and fitted to the 1: 1 binding model. Equilibrium dissociation constants (KD) are calculated by the ratio of kon to kDff. Reactants (2-4) are then used at 6 concentrations of 3-fold concentration series bracketing the observed Kd for reactant (1). Reactant (3) is diluted from a DMSO stock into PBS buffer for incubations. The antibody reactants (2) and (4) are diluted for incubations into PBS/0. l%BSA/0.02%Tween 20. Data for reactants (2-4) are analyzed using Octet Data Analysis Software 9.0 (ForteBio) and fitted to the 1: 1 binding model. Equilibrium dissociation constants (KD) are calculated by the ratio of kon to kDff.
EXAMPLE 9
CEA-TNIK Immune-stimulatory Compounds Retain Inhibitor Affinity for TNIK
[0637] The Kd for CEA-TNIK immune- stimulatory conjugates with TNIK inhibitors and the inhibitors as free, control compounds are determined using Bio-layer Inter ferometry with an Octet Red instrument (ForteBio) as follows. Dual N-terminal tagged (strep, GST) active kinase TNIK kinase (aa 1-367) is expressed as a recombinant protein by baculo virus in sf9 insect cells and purified by a GST-affinity column. The TNIK kinase is captured onto the surface of biotin- coated biosensor wells at several different loading concentrations. The analysis for each reactant is performed in the following steps: (1) baseline acquisition (60 s); (2) loading of the kinase domain onto the biotin coated biosensor (120 s); (3) second baseline acquisition (60 s); (4) association of the reactant (120 s); and (5) dissociation of reactant (480-900 s). First, the control compound is used at 6 concentrations of 3-fold concentration series diluted from a DMSO stock into PBS buffer for incubations. Data are analyzed using Octet Data Analysis Software 9.0 (ForteBio) and fitted to the 1: 1 binding model. Equilibrium dissociation constants (KD) are calculated by the ratio of kon to kDff. Next, the CEA-TNIK conjugates are then used at 6 concentrations of 3-fold concentration series bracketing the observed Kd for reactant (1).
Reactant (3) is diluted from a DMSO stock into PBS buffer for incubations. The antibody reactants (2) and (4) are diluted for incubations into PBS/0. l%BSA/0.02%Tween 20. Data for reactants (2-4) are analyzed using Octet Data Analysis Software 9.0 (ForteBio) and fitted to the 1: 1 binding model. Equilibrium dissociation constants (KD) are calculated by the ratio of kon to k0ff. The results show that the Kd of the tested CEA-TNIK immune- stimulatory conjugates is measured at 1-10 times the Kd of its control compound.
EXAMPLE 10
Immune-Stimulatory Conjugates Inhibit Signaling by A2aR without Processing
[0638] To demonstrate immune- stimulatory conjugates do not require extensive processing for activity, immune- stimulatory conjugates with A2aR inhibitors are tested in a short-term cell- based assay for antagonism of signaling by a cell surface GPCR. CHO transfectants expressing human A2aR are seeded into 96-well white bottom plates at 2-3xl04 cells/well in the absence of G418 20 hours prior to assay. Equimolar titrations of immune- stimulatory compounds and immune- stimulatory conjugates (conjugates containing the immune- stimulatory compounds at DARs 2 to 4) are added to the cells, incubated for 15-30 minutes, followed by addition of 10 nM adenine and 10 further minutes of incubation. Irrelevant immune- stimulatory compounds and conjugates are used as negative controls. (In some experiments, adenine deaminase (3U/ml) and adenosine 5' [ ,β-methylene] diphosphate (50uM) are added along with test items to lower cAMP baseline for the assay.) After the 10-minute incubation, cAMP levels are measured by an HTRF assay using a GS cAMP Assay Kit (CisBio) and an Envision multi-modal plate reader (Perkin-Elmer). The results show that the immune- stimulatory conjugates inhibit the cAMP increase generated by A2aR activation within minutes indicating that little to no processing is needed for immune- stimulatory activity and do so with IC50s close to those of the non- conjugated immuno stimulatory compound.

MG-132. After treatment, media is aspirated and cells are rinsed with ice cold PBS. Ice cold lysis buffer (20 mM TrisHCl pH 7.5, 150 mM NaCl, 1% Triton X-100, 2 mM EDTA and 10% glycerol) containing phosphatase and protease inhibitors is added to wells and cells are removed from the plate using a cell scraper. Lysates are transferred to a 1.5 ml tube and rocked for one hour at 4°C with vortexing every -15 minutes. Tubes are spun at 8500xg for 10 minutes and supernatants are drawn into an insulin needle twice. Cell lysates are frozen at -80°C. Protein concentration is determined using a BCA assay and equal amounts of samples are boiled with reducing loading buffer. The samples are then subjected to electrophoresis on 4-20%
polyacrylamide gels which are then transferred to PVDF membranes. Blocking and staining are done in 5% w/v soy milk PBS with 0.05% Tween 20 and washing using PBS with 0.05% Tween.
For PROTACs and immune-modulatory conjugates targeting TGFPR2, blots are incubated overnight with rocking at 4°C with 1:200 primary anti-TGFpR2 antibody (Santa Cruz, sc-17791).
For PROTACs and immune-modulatory conjugates targeting TGFpRl, blots are incubated overnight with rocking at 4°C with 1:3000 primary anti-TGFpRl antibody (R&D, MAB5871).
Loading controls are detected with 1: 15000 diluted primary antibody incubation at room temperature for 1 hour with rocking (Tubulin - Abeam, ab7291 ; Actin - Abeam, ab8224).
Secondary antibodies are diluted 1: 10000 and blots are incubated for 1 hour at room temperature with rocking (Jackson ImmunoResearch, 115-035-003 or 112-035-003). ECL reagent is used to detect the signal and blots are imaged using the ChemiDoc MP (Biorad). Analysis of densitometry is done using the ImageLab software and signals are adjusted based on loading control.
