Abstract

A method of treating a patient who has glioblastoma and/or gastric cancer includes administering to said patient a composition containing a population of activated T cells that selectively recognize cells in the patient that aberrantly express a peptide. A pharmaceutical composition contains activated T cells that selectively recognize cells in a patient that aberrantly express a peptide, and a pharmaceutically acceptable carrier, in which the T cells bind to the peptide in a complex with an MHC class I molecule, and the composition is for treating the patient who has glioblastoma and/or gastric cancer. A method of treating a patient who has glioblastoma and/or gastric cancer includes administering to said patient a composition comprising a peptide in the form of a pharmaceutically acceptable salt, thereby inducing a T-cell response to the glioblastoma and/or gastric cancer.

Claims

1. A method of eliciting an immune response in a patient who has cancer, comprising administering to the patient a composition comprising a population of activated T cells that selectively recognize the cancer cells that present a peptide consisting of the amino acid sequence of RLLDSVSRL (SEQ ID NO:

39),

wherein the activated T cells are produced by contacting T cells with the peptide loaded human class I or II MHC molecules expressed on the surface of an antigen-presenting cell for a period of time sufficient to activate the T cells,

wherein said cancer is selected from the group consisting of gastric cancer, melanoma, bladder cancer, and non-small cell lung cancer.

2. The method of claim 1, wherein the T cells are autologous to the patient.

3. The method of claim 1, wherein the T cells are obtained from a healthy donor.

4. The method of claim 1, wherein the T cells are obtained from tumor infiltrating lymphocytes or peripheral blood mononuclear cells.

5. The method of claim 1, wherein the activated T cells are expanded in vitro.

6. The method of claim 1, wherein the peptide is in a complex with the class I MHC molecule.

7. The method of claim 1, wherein the antigen presenting cell is infected with recombinant virus expressing the peptide.

8. The method of claim 7, wherein the antigen presenting cell is a dendritic cell or a macrophage.

9. The method of claim 5, wherein the expansion is in the presence of an anti-CD28 antibody and IL-12.

10. The method of claim 1, wherein the population of activated T cells comprises CD8-positive cells.

11. The method of claim 1, wherein the contacting is in vitro.

12. The method of claim 1, wherein the composition further comprises an adjuvant.

13. The method of claim 12, wherein the adjuvant is selected from the group consisting of anti-CD40 antibody, imiquimod, resiguimod, GM-CSF, cyclophosphamide, Sunitinib, bevacizumab, interferon-alpha, interferon-beta, CpG oligonucleotides and derivatives, poly-(I:

C) and derivatives, RNA, sildenafil, and particulate formations with poly(lactid co-glycolid) (PLG), virosomes, interleukin (IL)-1, IL-2, IL-4, IL-7, IL-12, IL-13, IL-15, IL-21, and IL-23.

14. The method of claim 1, wherein the immune response comprises a cytotoxic T cell response.

15. The method of claim 1, wherein the immune response is capable of killing the cancer cells.

16. The method of claim 1, wherein the class I MHC molecule is HLA-A*02.

17. The method of claim 1, wherein the cancer is non-small cell lung cancer.

18. A method of eliciting an immune response in a patient who has gastric cancer, melanoma, bladder cancer, and/or non-small cell lung cancer, comprising administering to said patient a composition comprising a peptide in the form of a pharmaceutically acceptable salt, wherein said peptide consists of the amino acid sequence of RLLDSVSRL (SEQ ID NO:

39), thereby inducing a T cell response to the gastric cancer, melanoma, bladder cancer, and/or non-small cell lung cancer.

19. The method of claim 18, wherein the T cell response is a cytotoxic T cell response.

20. The method of claim 18, wherein the cancer is non-small cell lung cancer.
