In vivo B-cell depletion in mouse models clearing patient-derived B-CLL cells
“B cell depletion by ublituximab was also observed in in vivo mouse models of the clearance of cells derived from a patient suffering from B cell chronic lymphocytic leukaemia (B-CLL).”
No in vivo MS model run; EAE feasibility questioned because of rodent CD20 cross-reactivity and strong immunogenicity in monkeys
“However, the feasibility of such a model due to ublituximab cross-reaction with rodent CD20 and its the strong immunogenicity observed in nonhuman primate studies, is questioned.”
EMA: SCID mouse B-CLL clearance studies are proof of concept for B-cell depletion, confirmed clinically
“The performed studies in immunocompromised mice models (SCID and SCID NOD) of the clearance of human B-CLL provide evidence that ublituximab can deplete tumoral B cell. This can be considered a proof of concept, also confirmed in clinical setting.”
