Peptides, combination of peptides, and cell based medicaments for use in immunotherapy against urinary bladder cancer and other cancers

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.

AI Technical Summary

Benefits of technology

The patent text describes a method of making peptides that can be used to diagnose cancer and other diseases. These peptides can be added to tissue samples to help with diagnosis and can also be used as biomarkers for urinary bladder cancer. The peptides can be added to the tissue sample to increase their stability or solubility. Overall, this method can help with the diagnosis and classification of diseased tissues.

Problems solved by technology

BCG treatment is in general well tolerated by patients but can be fatal especially by the immunocompromised patients.

The treatment of patients who failed the BCG therapy is challenging.

The patients who failed the BCG treatment are at high risk for developing of muscle-invasive disease.

In general, the treatment of advanced bladder cancer with muscle invasion known as muscle-invasive bladder carcinoma (MIBC) or metastatic bladder cancer is challenging and remained substantially unchanged over the last few decades.

Nowadays available options for treatment of progressed bladder cancer are insufficiently effective.

The adjuvant application of chemotherapy by the treatment of MIBC is limited by the high surgical complication rate after radical cystectomy.

Furthermore, patients with impaired renal function are ineligible for treatment with cisplatin.

The development of molecularly targeted therapies remains challenging due to high degree of genetic diversity of bladder cancer.

Since the constitutive expression of HLA class II molecules is usually limited to immune cells, the possibility of isolating class II peptides directly from primary tumors was previously not considered possible.

However, the identification of genes over-expressed in tumor tissues or human tumor cell lines, or selectively expressed in such tissues or cell lines, does not provide precise information as to the use of the antigens being transcribed from these genes in an immune therapy.
