Peptides and combination of peptides for use in immunotherapy against ovarian cancer and other cancers

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.

METHOD FOR PREDICTING THE SURVIVAL TIME OF A PATIENT SUFFERING FROM A CANCER
20230086718 · 2023-03-23 ·

The present invention relates to the prediction of the survival time of a patient suffering from a cancer. The inventors identified in blood from healthy donors a subpopulation of WIT cells that expresses CD73 and displays immunosuppressive phenotype and functions (i.e., production of immunosuppressive molecules and inhibition of αßT cell proliferation). Furthermore, they detected the presence of CD73+ γδ T cells in immune infiltrates of freshly resected breast cancer specimens. Altogether, these data suggest that part of γδ T cells infiltrated in the breast cancer microenvironment presents a regulatory phenotype characterized by CD73 expression, and are likely to display pro-tumor functions through the mechanisms they described in vitro. Thus, the invention relates to a method for predicting the survival time of a patient suffering from a cancer comprising i) determining in a sample obtained from the patient the level of Gamma/Delta T cells expressing CD73 ii) comparing the expression level determined at step i) with its predetermined reference value and iii) providing a good prognosis when the level of Gamma/Delta T cells expressing CD73 determined at step i) is lower than its predetermined reference value, or providing a bad prognosis when the level of Gamma/Delta T cells expressing CD73 determined at step i) is higher than its predetermined reference value.

Methods and Compositions for the Diagnosis of Ovarian Cancer
20230063827 · 2023-03-02 ·

A diagnostic reagent or device comprises at least one ligand capable of specifically complexing with, binding to, or quantitatively detecting or identifying the biomarker chloride intracellular channel protein 4 (CLIC4) or an isoform, pro-form, modified molecular form including posttranslational modification, or unique peptide fragment or nucleic acid fragment thereof. An alternative diagnostic reagent or device comprises ligand or ligands capable of specifically complexing with, binding to, or quantitatively detecting or identifying multiple tropomyosin biomarkers. Optionally, such reagent or device includes a signaling molecule and/or a substrate on which the ligand is immobilized. Other reagents and methods of diagnosing ovarian cancer include use of CLIC4 ligands and/or multiple tropomyosin ligands with an additional ovarian cancer biomarker. For example, CLIC4 combined with one or more of CLIC1 and/or one or multiple members of the tropomyosin family, e.g., TPM1, TPM2, TPM3 or TPM4, and further optionally including CTSD-30 kDa and/or PRDX-6, among other ovarian cancer biomarkers can form a characteristic diagnostic pattern or profile of expression that is diagnostic of the disease. Still other embodiments are described.

USE OF HUMAN EPIDIDYMIS PROTEIN 4 (HE4) FOR ASSESSING RESPONSIVENESS OF MUC 16-POSITIVE CANCER TREATMENT

The present invention relates to methods and kits or articles of manufacture related thereto that may find use, inter alia, in assessing responsiveness of cancers to MUC16 antagonists by monitoring HE4 expression. In some embodiments, the methods include measuring the level of expression of HE4 in a sample from a subject; comparing the level of expression of HE4 in the sample with the level of expression of HE4 in a sample previously obtained from the subject; and, optionally, administering to the subject a therapeutically effective amount of a MUC16 antagonist.
