ZILBRYSQ (zilucoplan sodium)
Zilbrysq treats adults with generalized myasthenia gravis who test positive for anti-acetylcholine receptor antibodies. As a complement inhibitor, it helps manage the autoimmune response that characterizes this condition. This therapy provides a targeted approach for patients whose immune systems produce specific antibodies that interfere with nerve and muscle communication.
How ZILBRYSQ Works
This drug works by binding to the C5 complement protein, which prevents it from breaking down into the components that form the terminal complement complex. This action is thought to reduce the buildup of these complexes at the neuromuscular junction. By limiting this specific immune activity, the medication helps protect the areas where nerves and muscles interact.

ZILBRYSQ Boxed Warning
SERIOUS MENINGOCOCCAL INFECTIONS ZILBRYSQ, a complement inhibitor, increases the risk of serious infections caused by Neisseria meningitidis [see Warnings and Precautions (5.1) ] . Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early.

WARNING: SERIOUS MENINGOCOCCAL INFECTIONS ZILBRYSQ, a complement inhibitor, increases the risk of serious infections caused by Neisseria meningitidis [see Warnings and Precautions (5.1) ] . Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early. Complete or update vaccination for meningococcal bacteria (for serogroups A, C, W, Y, and B) at least 2 weeks prior to the first dose of ZILBRYSQ, unless the risks of delaying therapy outweigh the risk of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccination against meningococcal bacteria in patients receiving a complement inhibitor. See Warnings and Precautions (5.1) for additional guidance on the management of the risk of serious infections caused by meningococcal bacteria. Patients receiving ZILBRYSQ are at increased risk for invasive disease caused by Neisseria meningitidis , even if they develop antibodies following vaccination. Monitor patients for early signs and symptoms of serious meningococcal infections and evaluate immediately if infection is suspected. Because of the risk of serious meningococcal infections, ZILBRYSQ is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called ZILBRYSQ REMS [see Warnings and Precautions (5.2) ] . WARNING: SERIOUS MENINGOCOCCAL INFECTIONS See full prescribing information for complete boxed warning. ZILBRYSQ increases the risk of serious and life-threatening infections caused by Neisseria meningitidis . ( 5.1 ) Complete or update meningococcal vaccination at least 2 weeks prior to the first dose of ZILBRYSQ, unless the risks of delaying ZILBRYSQ outweigh the risks of developing a serious infection.
