Disclosed herein are methods for selecting cancer patients for autologous cancer vaccine therapy and methods for predicting survival of cancer patients after autologous cancer vaccine therapy comprising, measuring the level of soluble programmed cell death protein-1 (sPD-1) in the blood of the patient.

Provided are novel anti-MFI2 antibodies and antibody drug conjugates, and methods of using such anti-MFI2 anti-bodies and antibody drug conjugates to treat cancer.

The present invention relates to a method of assessing, predicting or monitoring the sensitivity of a subject having a tumor or cancer to an immunotherapeutic molecule acting on the subject's T cells, to a method of selecting an appropriate treatment of cancer, to a method of screening or identifying a compound suitable for improving the treatment of a cancer, and to the use of corresponding kits. The method of predicting or monitoring the sensitivity of a subject having a tumor to an immunotherapeutic molecule acting on the subject's T cells typically comprises a step a) of determining, in a biological sample from said subject, the expression level of soluble CD25 (sCD25) and, when the expression level is determined, a step b) of comparing at least said expression level to a reference expression level, thereby assessing whether the subject having a tumor is responsive or resistant to the immunotherapeutic molecule.

Provided herein are methods and kits for predicting and monitoring a cancer patient's response to treatment with a therapeutic agent by measuring the amount of myeloid derived suppressor cells (MDSC) having the profile CDl11b.sup.+CD33.sup.+HLA-DR.sup.− and/or CDl11b.sup.+CD33.sup.+HLA-DR.sup.low, and optionally by further measuring various suppressive features of the patient's immune system. Also provided herein are methods of treating a cancer patient comprising as an initial step determining whether the cancer patient would be responsive to treatment with the therapeutic agent as described above and wherein the patient is found to be responsive, administering the therapeutic agent.

A set of phosphorylated peptides are presented by HLA A*0101, A*0201, A*0301, B*4402, B*2705, B*1402, and el B*0702 on the surface of melanoma cells. They have the potential to (a) stimulate an immune response to the cancer, (b) to function as immunotherapeutics in adoptive T-cell therapy or as a vaccine, (c) to facilitate antibody recognition of the tumor boundaries in surgical pathology samples, and (d) act as biomarkers for early detection of the disease. Phosphorylated peptides are also presented for other cancers.

Antibodies specific to MUC18 (a.k.a. MCAM or CD146) and antibody-drug conjugates (ADCs) comprising such. Also provided herein are uses the the anti-MUC18 antibodies or ADCs for therapeutic and diagnostic purposes.

The disclosure features compositions and methods that may be used to detect the presence of tumor cell-derived exosomes in a patient (e.g., a human patient) having cancer. The compositions and methods described herein may also be used to evaluate the patient's prognosis, as well as monitor the likelihood of the patient to benefit from therapy, such as immunotherapy. The disclosure also features antibodies that specifically bind chondroitin sulphate proteoglycan 4 (CSPG4), as well as antigen-antibody complexes containing the same.

The present invention provides methods for identifying circulating melanoma cells (CMCs) in a biological sample and methods for diagnosing metastatic melanoma in a subject. The methods disclosed can be used on non-enriched blood samples to identify CMC using detectable agents that are specific for a biomarker of CMCs and assessing the morphology of the cells having the detectable agents. The presence or absence of a detectable agent in combination with morphological characteristics of the cells can be used diagnose a subject with metastatic melanoma based on the number of CMCs is present in the sample.

The present invention relates inter alia to the development of monoclonal antibodies against Loricrin and methods for determining whether a subject with melanoma has an increased risk of metastasis using said antibodies.

Nucleic acids and proteins having a mutant C-RAF sequence, and methods of identifying patients having cancer who are likely to benefit from a combination therapy and methods of treatment are provided.
