Abstract: The present invention relates to a method of predicting assessing or monitoring the sensitivity of a subject having a cancer to a combination therapy, preferably to a therapy combining an immunotherapeutic agent and an anti-angiogenic agent, and to corresponding kits and uses thereof. The method of predicting, assessing or monitoring the sensitivity of a subject having a cancer or malignant tumor to a proposed combination therapy typically comprises a step a) of determining, in a biological sample from said subject, the presence, absence or expression level or proportion of at least one biomarker, for example at least two biomarkers, and when the expression level or proportion is determined a step b) of comparing said expression level or proportion to reference expression level(s) or to reference expression ratio(s), thereby predicting, assessing or monitoring whether the subject having a tumor is responsive or resistant to the proposed combination therapy.

Abstract: The present invention relates to a method of predicting, assessing or monitoring the sensitivity of a subject having a cancer to an immunotherapy, preferably to an immunotherapy combining at least two immunotherapeutic agents, and to corresponding kits and uses thereof. The method of predicting, assessing or monitoring the sensitivity of a subject having a tumor to an immunotherapy typically comprises a step of assessing, before any immunotherapeutic treatment step in the subject, the presence of CD4+CD25highCD39high T cells in a tumor sample of the subject, the presence of CD4+CD25highCD39high T cells in the tumor sample of the subject being indicative of sensitivity of the subject to the immunotherapy, and the absence of CD4+CD25highCD39high T cells in the tumor sample of the subject being indicative of resistance of the subject to the immunotherapy.

Abstract: Humanized or chimeric anti-CD81 (cluster of differentiation 81) monoclonal antibodies are provided. The antibodies bind to human CD81, and find use in various therapeutic methods, including without limitation the reduction or prevention of tumor metastasis. Further provided are heavy chain and light chain variable region sequences as well as associated complementarity-determining region (CDR) sequences.
