Abstract

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

Claims

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

72), wherein said cancer is selected from the group consisting of small cell lung cancer, non-small cell lung cancer, small cell lung cancer, renal cell cancer, brain cancer, gastric cancer, colorectal cancer, hepatocellular cancer, pancreatic cancer, prostate cancer, leukemia, breast cancer, Merkel cell carcinoma, melanoma, ovarian cancer, urinary bladder cancer, uterine cancer, gallbladder and bile duct cancer, and esophageal cancer.

2. The method of claim 1, wherein the activated T lymphocytes are produced by a method comprising contacting in vitro T cells with the peptide loaded onto a human class I MHC molecule expressed on the surface of an antigen-presenting cell for a period of time sufficient to activate said T cells.

3. The method of claim 2, wherein the antigen presenting cell is infected with a recombinant virus expressing the peptide.

4. The method of claim 3, wherein the antigen presenting cell is a dendritic cell or a macrophage.

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

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

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

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

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

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

11. The method of claim 10, wherein the adjuvant is selected from the group consisting of anti-CD40 antibody, imiquimod, resiquimod, 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.

12. The method of claim 8, wherein the expansion is in the presence of an anti-CD28 antibody and IL-12.

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

14. The method of claim 1, wherein the cancer is small cell lung cancer.

15. The method of claim 1, wherein the cancer is ovarian cancer.

16. The method of eliciting an immune response of claim 1, wherein the cancer cells are killed.
