Abstract

A method of treating a patient who has melanoma 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 melanoma. A method of treating a patient who has melanoma 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 melanoma.

Claims

1. A method of treating a patient who has melanoma, comprising administering to said patient a composition comprising a population of activated T cells that selectively recognize cells in the patient that aberrantly express a peptide, wherein said peptide consists of the amino acid sequence of SLYSYFQKV (SEQ ID NO:

33), wherein the peptide is in a complex with an MHC molecule.

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 derived from tumor infiltrating lymphocytes or peripheral blood mononuclear cells.

5. The method of claim 1, further comprising expanding T cells in vitro.

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

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

8. The method of claim 7, wherein the adjuvant is selected from the group consisting of imiquimod, resiguimod, GM-CSF, cyclophosphamide, Sunitinib, bevacizumab, interferon-alpha, CpG, oligonucleotides and derivatives, poly-(I:

C) and derivatives, RNA, sildenafil, and particulate formations with PLG and virosomes.

9. The method of claim 1, wherein the activated T cells are cytotoxic T cells produced by contacting T cells, in vitro, with an antigen presenting cell that expresses the peptide in a complex with an MHC class I molecule on the surface of the antigen presenting cell, for a period of time sufficient to activate said T cell specifically against the peptide.

10. The method of claim 9, wherein the antigen presenting cell is infected with a recombinant virus expressing the peptide.

11. The method of claim 10, wherein the antigen presenting cell is a dendritic cell or a macrophage.

12. The method of claim 9, further comprising stimulating the activated T cells in the presence of an anti-CD28 antibody and IL-12 to clonally expand the T cells.

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 melanoma is uveal melanoma.

15. A method of treating a patient who has melanoma, 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 SLYSYFQKV (SEQ ID NO:

33), thereby inducing a T-cell response to the melanoma.
