Crovalimab

Description: Crovalimab (SKY59, RO7112689) is an Fc-engineered and pH-dependent humanised monoclonal antibody that binds to complement C5 and blocks its cleavage into C5a and C5b, thereby inhibiting MAC formation and intravascular haemolysis. It can rebind to the FcRn receptor under acidic pH conditions and return to the bloodstream, making it suitable for the treatment of paroxysmal nocturnal haemoglobinuria (PNH). Target: Complement System. References: Taku Fukuzawa, et al. Long lasting neutralization of C5 by SKY59, a novel recycling antibody, is a potential therapy for complement-mediated diseases.
