Compliance for Clinical Use

Mechanism and Biochemical Profile

Pegcetacoplan acetate is a PEGylated cyclic peptide that directly binds complement components C3 and C3b, effectively blocking convertase-mediated C3 cleavage and downstream complement cascade activation. By preventing C3b opsonization and membrane attack complex assembly, the compound inhibits both extravascular and intravascular hemolysis while preventing tissue damage, supporting its therapeutic utility in complement-mediated diseases such as paroxysmal nocturnal hemoglobinuria, geographic atrophy, and C3 glomerulopathy.

Appendix RUO and cGMP Quality Standards
