METHOD FOR IDENTIFYING CANCER PATIENTS THAT BENEFIT FROM ANTI-CLEVER-1 TREATMENT

A method for pre-treatment identification of cancer patients that respond to anti-CLEVER-1 therapy comprising an administration of an agent capable of binding to CLEVER-1 in a patient. In the method, the presence of CLEVER-1 expressing cells is detected in a tumor sample obtained from a cancer patie...

Summary:A method for pre-treatment identification of cancer patients that respond to anti-CLEVER-1 therapy comprising an administration of an agent capable of binding to CLEVER-1 in a patient. In the method, the presence of CLEVER-1 expressing cells is detected in a tumor sample obtained from a cancer patient, by immunohistochemistry staining by a mouse monoclonal IgG2a kappa STAB-1 antibody (clone 4G9), and a percentage of intra-tumoral CLEVER-1 expressing cells from the total amount of viable intra-tumoral cells present in the stained sample is calculated. A tumor sample which shows substantial percentage of CLEVER-1 expressing intra-tumoral cells is an indication that the cancer patient is responsive to the anti-CLEVER-1 therapy. L'invention concerne une méthode d'identification de prétraitement de patients cancéreux qui répondent à une thérapie anti-CLEVER-1 comprenant une administration d'un agent capable de se lier à CLEVER-1 chez un patient. Dans la méthode, la présence de cellules exprimant CLEVER-1 est détectée dans un échantillon tumoral obtenu d'un patient cancéreux, par coloration immunohistochimique par un anticorps IgG2a kappa STAB-1 monoclonal murin (clone 4G9), et un pourcentage de cellules exprimant CLEVER-1 intratumorales à partir de la quantité totale de cellules intratumorales viables présentes dans l'échantillon coloré est calculé. Un échantillon de tumeur qui présente un pourcentage substantiel de cellules intratumorales exprimant CLEVER-1 est une indication que le patient cancéreux est sensible à la thérapie anti-CLEVER-1.
