Title
(EN) BIOMARKERS FOR CD47 BLOCKADE THERAPY
(FR) BIOMARQUEURS POUR UNE THÉRAPIE DE BLOCAGE DE CD47
Abstract
(EN)
Subjects responsive to a CD47 blocking agent, such as SIRPαFc, exhibit an elevated level of expression of one or more markers. Accordingly, subjects with elevated levels of the markers are treated with CD47 blocking agents while subject that are not responsive and 5 do not have elevated levels of markers are not selected for treatment. The markers are selected from CHIT1, SPP1, FCγR3A and FCγR2A.
(FR)
Des sujets sensibles à un agent de blocage de CD47, tel que SIRPαFc, présentent un taux élevé d'expression d'un ou de plusieurs marqueurs. En conséquence, des sujets ayant des taux élevés des marqueurs sont traités avec des agents de blocage de CD47 tandis que les sujets qui n'y sont pas sensibles et qui ne présentent pas de taux élevés de marqueurs ne sont pas sélectionnés pour le traitement. Les marqueurs sont choisis parmi CHIT1, SPP1, FCγR3A et FCγR2A.
