EPYSQLI (eculizumab-aagh)
EPYSQLI is indicated for the treatment of Paroxysmal Nocturnal Hemoglobinuria; Atypical Hemolytic Uremic Syndrome; Generalized Myasthenia Gravis.
How EPYSQLI Works
EPYSQLI is a monoclonal antibody that binds with high affinity to the complement protein C5, inhibiting its cleavage into C5a and C5b. This action prevents the generation of the terminal complement complex C5b-9, which otherwise mediates intravascular hemolysis in PNH and thrombotic microangiopathy in aHUS. In patients with gMG, the drug is presumed to work by reducing the deposition of this terminal complement complex at the neuromuscular junction.

EPYSQLI Boxed Warning
SERIOUS MENINGOCOCCAL INFECTIONS Eculizumab products, complement inhibitors, increase the risk of serious infections caused by Neisseria meningitidis [ see Warnings and Precautions ( 5.1 ) ].

WARNING: SERIOUS MENINGOCOCCAL INFECTIONS Eculizumab products, complement inhibitors, increase 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 EPYSQLI, unless the risks of delaying therapy with EPYSQLI outweigh the risk of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations 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 eculizumab products 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, EPYSQLI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called EPYSQLI REMS [ see Warnings and Precautions ( 5.2 ) ]. WARNING: SERIOUS MENINGOCOCCAL INFECTIONS See full prescribing information for complete boxed warning. Eculizumab products increase the risk of serious and life-threatening infections caused by Neisseria meningitidis. Complete or update meningococcal vaccination at least 2 weeks prior to the first dose of EPYSQLI, unless the risks of delaying EPYSQLI outweigh the risk of developing a serious infection. Comply with the most current Advisory Committee on Immuniz
EPYSQLI is a lower-cost alternative to Soliris with no clinically meaningful differences. Requires prescriber approval to substitute.
