The invention provides methods or compositions for enhancing the potency of a targeted cancer immunotherapy in a subject by using a superantigen in combination with an immunopotentiator (for example, a PD-1 inhibitor).

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.

Provided is a ROBO1 CAR-NK cell carrying a suicide gene, and a preparation method and application thereof. In order to increase the safety and controllability of a CAR-NK therapy, on the basis of a present ROBO1 CAR-NK cell, a suicide gene switch element is integrated into a genome by means of a lentiviral transfection technology to form a CAR-NK carrying a suicide gene. By adding the suicide gene, the CAR-NK cell can be better controlled, and the clinical safety is further improved.

The invention relates to a peptide comprising an amino acid sequence selected from the group consisting of (i) SEQ ID NO: 1 to SEQ ID NO: 216, and (ii) a variant sequence thereof which maintains capacity to bind to MHC molecule(s) and/or induce T cells cross-reacting with said variant peptide, or a pharmaceutically acceptable salt thereof.

Disclosed is the use of a combination of an anti-PD-1 antibody and a VEGFR inhibitor in the preparation of a drug for treating cancers.

The present invention relates to immunoconjugates anti-AXL antibodies and compositions for treatment of non-small cell lung cancer.

Provided is a method for enhancing the potency of a targeted cancer immunotherapy in a subject by using a superantigen in combination with a PD-1 inhibitor.

The present invention relates to T cell receptors (TCRs) that bind the HLA-A*02 restricted peptide SLLQHLIGL (SEQ ID NO: 1) derived from the germline cancer antigen PRAME. Said TCRs may comprise non-natural mutations within the alpha and/or beta variable domains relative to a native PRAME TCR. The TCRs of the invention are particularly suitable for use as novel immunotherapeutic reagents for the treatment of malignant disease.

Novel chimeric antigen receptors (CARs) are provided. When the CARs herein are expressed on the surface of immune cells, such immune cells may be directed to osteosarcoma cells as demonstrated with our in vivo data. In a murine intraperitoneal model, the tumor growth was significantly delayed for T cells expressing a CAR comprising a scFv from TP1 or TP3 antibodies. Immune cells expressing the CARs herein display therapeutic effect in the form of decreased tumor volume in a murine model simulating metastatic osteosarcoma. Combined with the finding that stem cells from healthy bone marrow were not significantly affected by T cells expressing any of the CARs, this disclosure provides an attractive cell therapeutic alternative for treatment of osteosarcoma.

A method of selecting a treatment for a subject having cancer is disclosed. The method comprises: (a) determining a level of catalytic activity of at least one DNA repair enzyme in a biological sample of the subject; and (b) selecting an immune checkpoint regulator as a treatment for a subject having a statistically significant different level of catalytic activity of said DNA repair enzyme as compared to the catalytic activity of said DNA repair enzyme in a biological sample of a healthy subject.
