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.

First claim

The invention claimed is:

1. A method of treating cancer in a HLA-A*02+ patient having a cancer overexpressing a SPINK2 polypeptide comprising the amino acid sequence of SEQ ID NO: 251 and presenting at its surface a peptide consisting of SEQ ID NO: 251 in the context of a complex with an MHC class I molecule, said method comprising administering to said patient an effective amount of activated antigen-specific CD8+ cytotoxic T cells to selectively eliminate the cancer cells, wherein said activated antigen-specific CD8+ cytotoxic T cells are produced by contacting CD8+ cytotoxic T cells with an antigen presenting cell presenting at its surface a peptide consisting of SEQ ID NO: 251 in the context of a complex with an MHC class I molecule in vitro, wherein said cancer is selected from the group consisting of acute myeloid leukemia, lymphoid neoplasm diffuse large B-cell lymphoma, and non-Hodgkin lymphoma.

2. The method of claim 1 , wherein the cytotoxic T cells produced by contacting CD8+ cytotoxic T cells with an antigen presenting cell presenting at its surface a peptide consisting of SEQ ID NO: 251 in the context of a complex with an MHC class I molecule are cytotoxic T cells autologous to the patient.

3. The method of claim 1 , wherein the cytotoxic T cells produced by contacting CD8+ cytotoxic T cells with an antigen presenting cell presenting at its surface a peptide consisting of SEQ ID NO: 251 in the context of a complex with an MHC class I molecule are cytotoxic T cells obtained from a healthy donor.

4. The method of claim 1 , wherein the cytotoxic T cells produced by contacting CD8+ cytotoxic T cells with an antigen presenting cell presenting at its surface a peptide consisting of SEQ ID NO: 251 in the context of a complex with an MHC class I molecule are cytotoxic T cells isolated from tumor infiltrating lymphocytes or peripheral blood mononuclear cells.

5. The method of claim 1 , wherein the cytotoxic T cells produced by contacting CD8+ cytotoxic T cells with an antigen presenting cell presenting at its surface a peptide consisting of SEQ ID NO: 251 in the context of a complex with an MHC class I molecule are expanded in vitro before being administered to the patient.

6. The method of claim 5 , wherein the cytotoxic T cells are expanded in vitro in the presence of an anti-CD28 antibody and IL-12.

7. The method of claim 1 , wherein the effective amount of activated antigen-specific CD8+ cytotoxic T cells to selectively eliminate the cancer cells are administered in the form of a composition.

8. The method of claim 7 , wherein said composition further comprises an adjuvant.

9. The method of claim 8 , wherein said adjuvant is selected from imiquimod, resiquimod, GM-CSF, cyclophosphamide, sunitinib, interferon-alpha, CpG oligonucleotides, poly-(I:C), RNA, sildenafil, particulate formulations with poly(lactid co-glycolid) (PLG) and virosomes.

10. The method of claim 1 , wherein the antigen presenting cell is a dendritic cell or a macrophage.

11. The method of claim 1 , wherein the antigen presenting cell is infected with a recombinant virus expressing the peptide consisting of SEQ ID NO: 251.

12. The method of claim 1 , wherein the antigen presenting cell is an artificial antigen presenting cell (aAPC) comprising an anti-CD28 antibody coupled to its surface.

13. The method of claim 1 , wherein the cancer is acute myeloid leukemia.
