| Publication Date: | November 27, 2012 |
| Appl. No: | 12/571602 |
| Application Filed: | October 01, 2009 |
| Abstract: | The present invention relates to immunotherapeutic peptides and their use in immunotherapy, in particular the immunotherapy of cancer. The present invention discloses tumor-associated T-helper cell peptide epitopes, alone or in combination with other tumor-associated peptides that serve as active pharmaceutical ingredients of vaccine compositions which stimulate anti-tumor immune responses. In particular, the composition of the peptides of the present invention can be used in vaccine compositions for eliciting anti-tumor immune responses against gliomas. |

| Claim: | 7. The pharmaceutical composition according to claim 6 , wherein the adjuvant is selected from the group consisting of colony-stimulating factors, GM-CSF, imiquimod, and resiquimod. |
| Claim: | 8. The pharmaceutical composition according to claim 6 , comprising two to four adjuvants. |
| Claim: | 9. The pharmaceutical composition according to claim 8 , wherein at least two of the adjuvants are selected from the group consisting of CP-870,893, CpG7909, GM-CSF, imiquimod, and resiquimod. |
| Claim: | 10. The pharmaceutical composition according to claim 1 , additionally comprising at least one antigen presenting cell. |
| Claim: | 11. The pharmaceutical composition according to claim 10 , wherein the antigen presenting cell is a dendritic cell. |
| Claim: | 12. The pharmaceutical composition according to claim 10 , wherein the at least one antigen presenting cell: a) is pulsed or loaded with the peptide; or b) comprises an expression construct encoding the peptide. |
| Claim: | 13. The pharmaceutical composition of claim 1 , wherein the composition is administered intravenously, infra-arterially, intra-peritoneally, intramuscularly, intradermally, intratumorally, orally, dermally, nasally, buccally, rectally, vaginally, by inhalation, or by topical administration. |
| Claim: | 14. A method for treating and/or preventing a cancer in a patient, the method comprising administering to the patient a therapeutically effective amount of the pharmaceutical composition of claim 1 . |
| Claim: | 15. The method according to claim 14 , wherein the pharmaceutical composition is an anti-cancer vaccine. |
| Claim: | 16. The method of claim 15 , wherein the cancer is one or more of cancer of the buccal cavity and/or pharynx, cancer of the digestive tract, cancer of the colon, rectum, or anus, cancer of the respiratory tract, breast cancer, cancer of the cervix uteri, vagina, or vulva, cancer of the uterine corpus or ovary, cancer of the male genital tract, cancer of the urinary tract, bone or soft tissue cancer, Kaposi sarcoma, melanoma of the skin, ocular melanoma, non-melanoma eye cancer, cancer of the brain and central nervous system, cancer of the thyroid and other endocrine glands, Hodgkin Lymphoma, Non-Hodgkin Lymphoma, myeloma, renal cancer, colorectal cancer, lung cancer, breast cancer, pancreatic cancer, prostate cancer, gastric cancer, GIST or glioblastoma. |
| Claim: | 17. The method according to claim 15 , wherein the cancer is colorectal cancer. |
| Claim: | 18. The pharmaceutical composition according to claim 1 , wherein the second immunogenic peptide is selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 4 to SEQ ID NO: 12, and a variant thereof that is at least 80% identical to that of SEQ ID NO:1, SEQ ID NO: 2, or SEQ ID NO: 4 to SEQ NO: 12. |
| Claim: | 19. The pharmaceutical composition of claim 1 , wherein the second peptide consists of a core sequence consisting of SEQ ID NO: 1, SEQ ID NO: 2, or SEQ ID NO: 4 to SEQ ID NO:7 with extensions of 1 to 10 amino acids on the C-terminal and/or the N-terminal of the core sequence. |
| Claim: | 20. The pharmaceutical composition, of claim 1 , wherein the second peptide consists of an amino acid sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 4 to SEQ ID NO: 8. |
