## 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

### Claim 1

A method of treating a patient who has cancer, comprising administering to said patient a population of activated T cells that kill cancer cells that present a peptide consisting of the amino acid sequence of ALYHQSPLL (SEQ ID NO: 45),
wherein said cancer is selected from head and neck squamous cell carcinoma, non-small cell lung cancer, esophageal cancer, and ovarian cancer.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 1)

The method of claim 1, wherein the population of activated T cells are administered in the form of a composition.

### Claim 7 (depends on 6)

The method of claim 6, wherein the composition further comprises an adjuvant.

### Claim 8 (depends on 7)

The method of claim 7, wherein the adjuvant is selected from 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, particulate formulations with poly(lactide co-glycolide) (PLG), virosomes, interleukin (IL)-1, IL-2, IL-4, IL-7, IL-12, IL-13, IL-15, IL-21, and IL-23.

### Claim 9 (depends on 1)

The method of claim 1, wherein the activated T cells are cytotoxic T cells produced by contacting T cells 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.

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 1)

The method of claim 1, wherein the cancer is head and neck squamous cell carcinoma.

### Claim 12 (depends on 1)

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

### Claim 13 (depends on 1)

The method of claim 1, wherein the cancer is esophageal cancer.

### Claim 14 (depends on 1)

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

### Claim 15

A method of eliciting an immune response in a patient who has cancer, comprising administering to said patient a population of activated T cells that kill cancer cells that present a peptide consisting of the amino acid sequence of ALYHQSPLL (SEQ ID NO: 45),
wherein said cancer is selected from head and neck squamous cell carcinoma, non-small cell lung cancer, esophageal cancer, and ovarian cancer.

### Claim 16 (depends on 15)

The method of claim 15, wherein the activated T cells are cytotoxic T cells produced by contacting T cells 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.

### Claim 17 (depends on 15)

The method of claim 15, wherein the cancer is head and neck squamous cell carcinoma.

### Claim 18 (depends on 15)

The method of claim 15, wherein the cancer is non-small cell lung cancer.

### Claim 19 (depends on 15)

The method of claim 15, wherein the cancer is esophageal cancer.

### Claim 20 (depends on 15)

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