Overview

Ra Pharmaceuticals developed synthetic macrocyclic peptide drugs targeting the complement system. Its lead asset, zilucoplan—a subcutaneous C5 inhibitor—completed Phase II trials for gMG and PNH and entered Phase III for gMG before the company was acquired by UCB in April 2020. Preclinical programs targeted additional complement-related indications. Zilucoplan showed promise as a once-daily self-administered therapy with potential applications across several rare autoimmune disorders.[2][4]
