Definitions
- Diagnostic kit for a cancer secreting hCG or hCG fragments and means intended for the therapy of such cancer.
- the present invention relates to a method for the treatment of cancer secreting hCG or fragments of hCG and means for implementing this method.
- Human gonadotropic chorionic hormone Human gonadotropic chorionic hormone
- hCG is an oligomeric glycoprotein consisting of the non-covalent association of two subunits ⁇ (hCG- ⁇ ) and ⁇ (hCG- ⁇ ). It belongs to the family of gonadothyreotropic hormones also comprising folliculotropic hormone (FSH), luteotropic hormone (LH) and thyreotropic hormone (TSH). HCG is secreted physiologically by the trophoblast from the start of pregnancy and stimulates the corpus luteum to maintain the synthesis of steroid hormones essential for implantation of the embryo.
- FSH folliculotropic hormone
- LH luteotropic hormone
- TSH thyreotropic hormone
- hCG and / or its subunits are also secreted by a majority of trophoblastic tumors and certain non-trophoblastic tumors, thus constituting biological markers which can help in the diagnosis or prognosis and in the monitoring of these tumors (Bellet and al. Rev. Prat. 40: 1677-1990).
- hCG- ⁇ is detectable in healthy men ( ⁇ 1 ng / ml) and women over 45 years of age without menopause ( ⁇ 3 ng / ml). In contrast, hCG- ⁇ is not detectable in the normal population.
- trophoblastic tumors In the case of trophoblastic tumors, it has been shown that benign (hydatidiform moles) and malignant (choriocarcinomas) placental tumors are characterized by an important serum hCG / hCG- ⁇ ratio: the percentage of free hCG which is 0.05 to 1% during normal pregnancies amounts to 1-5% in the case of moles and exceeds 5% in choriocarcinomas.
- This serum hCG / hCG- ⁇ ratio is used as a control for the development of testicular tumors: a percentage of hCG- ⁇ becoming less than 5% is often characteristic of a favorable development of the tumor during treatment. This ratio will rise quickly in the event of an unfavorable development or a relapse.
- hCG- ⁇ not detectable in healthy individuals, is found in many patients with certain non-trophoblastic tumors (tumors of the bladder, pancreas, cervix, tumors without primitive found, endometrial and lung tumors).
- the subject of the present invention is a method of treating cancer secreting hCG or fragments of hCG which consists in
- the polypeptides are formed by a chain of 9 to 40 amino acids corresponding to a part of the primary sequence of hCG. They may in particular be polypeptides comprising from 15 to 40 amino acids or, in the case of polypeptides capable of being recognized by cytotoxic T lymphocytes, shorter polypeptides having in particular from 9 to 11 amino acids.
- set of polypeptides covering at least part of the primary sequence of hCG denotes a set of polypeptides as defined above which correspond to successive sequences of hCG or of its fragments or better which correspond to sequences overlapping.
- At least one set of polypeptides will be used which covers the primary sequence of the ⁇ subunit of hCG or at least part of this sequence.
- the synthesis of the ⁇ subunit is dependent on an ultigenic group comprising 7 genes (Talmadge et al., Nucl. Acids Res. 12, 8415, 1984). Analysis of the nucleotic sequences shows that three of these genes (1, 3, 5) have an identical structure, four others of these genes (2, 6, 7 and 8) encode a variant at codon 117 with substitution. alanine instead of an aspartic acid.
- a study of gene expression shows that genes 1, 3 and 5 are expressed by the normal placenta.
- tumourogenesis processes involving non-trophoblastic cells the expression of several genes leads to both the secretion of the normal protein and of a protein mutated to 117.
- ⁇ subunit denotes both the normal protein and the protein mutated at 117.
- polypeptide corresponding to the antigen responsible for the state of immunization means a polypeptide which has the same sequence as one of the polypep ⁇ tides responsible for the state of immunization or a sequence resulting from the combination of sequences at least partial of the polypeptides responsible for the state of immunization.
- the state of immunization with respect to one of the polypeptides can be identified by a test for stimulating the proliferation of T lymphocytes by the polypeptides, or also by a test for cytotoxicity of T lymphocytes against vis the polypeptides.
- the recognized polypeptides are formed by a sequence of at least 9 amino acids corresponding to a part of the primary sequence of 1'hCG.
- the polypeptides interact with the class I molecules of the major histocompatibility complex of the patient. Each class I molecule interacts with peptides with specific motifs.
- the present invention also relates to a diagnostic kit for a cancer secreting hCG or hCG fragments comprising a set of polypeptides covering at least part of the primary sequence of 1'hCG.
- the subject of the present invention is also a composition intended for the immunotherapy of cancers secreting hCG or hCG fragments comprising an effective dose of a polypeptide corresponding to at least part of the primary sequence of hCG and in particular a polypeptide corresponding to at least part of the primary sequence of the hCG ⁇ subunit and a pharmaceutically acceptable vehicle.
- the present invention also relates to the use of a polypeptide corresponding to at least a part of the primary sequence of 1'hCG and in particular of a polypeptide corresponding to at least a part of the primary sequence of the ⁇ subunit hCG for the manufacture of a composition for the immunotherapy of cancers secreting hCG or fragments of hCG.
- poly ⁇ peptides can be used in free form or in a more immunogenic form, in particular a form in which the peptide is coupled to a polylysine matrix according to the MAP technique (Posnett et al. J. Biol. Chem. 263, 17, 1988).
- the polypeptide is advantageously administered with an adjuvanting immunity.
- adjuvants of immunity we may cite muramyldipeptide and SAF-1 (Allison et al., J. Immunol. Methods 45, 157, 1986).
- polypeptide can be protected at its NH 2 and COOH terminal ends in order to reduce the risks of degradation.
- the BCG vaccine (Bacillus Calmette Guérin) constituted by living attenuated strains of tuberculous bacillus (see in particular D. Lamm et al, New England Journal of Medicine 325, 17, 1205, 1991).
- the present invention therefore further relates to a composition intended for the immunotherapy of cancers secreting hCG or hCG fragments comprising an effective dose of a polypeptide corresponding to at least part of the primary sequence of hCG and an effective dose of BCG in a pharmaceutically acceptable vehicle.
- immunotherapy can be carried out with doses of polypeptides from 1 to 100 mg administered in particular at the level of the tumor.
- the polypeptides can be administered in the case of bladder cancer, as is already practiced in the case of immunotherapy with BCG, that is to say by intravesical instillation one week after resection. tumor, then this administration is repeated every week for 6 weeks and additional intravesical administration is performed 3, 6, 12, 18 and 24 months later.
- Percutaneous or general administrations are also possible. Description of the figures.
- Fig. 1 shows the proliferation of lymphocytes from a patient with bladder cancer in the presence of hCG, free ⁇ and ⁇ subunits and various polypeptides.
- Fig. 2 shows the proliferation of lymphocytes from another patient with bladder cancer in the presence of free ⁇ and ⁇ subunits and different polypeptides.
- Fig. 3A shows the proliferation of lymphocytes from a patient with bladder cancer in the presence of different polypeptides.
- Fig. 3B shows the proliferation of lymphocytes from a patient with testicular cancer in the presence of different polypeptides.
- PBMC mononuclear cells
- the PBMCs are cultured (2 ⁇ 10 5 cells per well) in RPMI 1640 supplemented with 10% human AB serum, 2 mM L-glutamine, 100 IU / ml of penicillin and 100 ⁇ g / ml of streptomycin, in the presence of polypeptide at different concentrations.
- the cells are then incubated at 37 ° C with 5% C0 2 for 5 days.
- a ⁇ Ci of tritiated thymidine is then added to each well.
- the cells are collected 18 hours later and The incorporation of the radioactivity is analyzed by spectrometry in a scintillation liquid using a ⁇ counter.
- FIG. 1 We have given in FIG. 1 the results of proliferation of lymphocytes from a patient with bladder cancer in the presence
- results demonstrate a significant proliferation with the polypeptide corresponding to the sequence 95-115 of the ⁇ subunit of hCG as well as with the polypeptide corresponding to the sequence 25-59 of the ⁇ subunit of the hCG.
- the 95-115 hCG- ⁇ and 25-59 hCG- ⁇ polypeptides can be used for immunotherapy in the patient tested.
- FIG. 2 results of the same type on lymphocytes from another patient with bladder cancer.
- the results demonstrate a significant proliferation with the polypeptide corresponding to the sequence 31 - 50 of the ⁇ subunit of hCG as well as with the polypeptide corresponding to the sequence 41 - 61 of the ⁇ subunit of the hCG.
- hCG- ⁇ and 41-61 hCG- ⁇ polypeptides 31 - 50 can be used for immunotherapy.
- FIG. 3A We have given in FIG. 3A the results of PBMC proliferation tests of another patient with bladder cancer secreting the ⁇ subunit of hCG in the presence of different polypeptides covering the entire ⁇ subunit of hCG (50 ⁇ m).
- T cells from a patient with testicular cancer secreting hCG- ⁇ , proliferated in the presence of the peptide hCG- ⁇ (20-47) (Fig. 3B).
- PBMCs isolated by Ficoll gradient are tested for their cytotoxic action against autologous targets (patient B lymphocytes immortalized by Epstein-Barr virus) labeled with chromium 51 and serving as cells presenting the hCG polypeptides. . Cytotoxicity is evaluated by counting the radioactivity due to the release of 51 Cr from the lysed target.
