Generalized Myasthenia Gravis Clinical Trial
Official title:
A Phase 3, Randomized, Double-Blind, Placebo-Controlled Study With an Open-label Extension Period to Evaluate the Efficacy and Safety of Telitacicept in Patients With Generalized Myasthenia Gravis
The purpose of this study is to evaluate the efficacy and safety of telitacicept in the treatment of generalized myasthenia gravis.
Myasthenia gravis (MG) is an autoimmune disease that affects the neuromuscular junction on the postsynaptic membrane. The predominant manifestation is muscle weakness, which typically worsens with repeated muscle exertion, such that function is usually the best in the morning with more pronounced weakness at the end of the day. A major challenge in MG is the lack of therapies that cure the disease. Telitacicept is a fully human TACI-Fc fusion protein that targets B-lymphocyte stimulator (BLyS) and A proliferating-inducing ligand (APRIL), neutralizing their interactions with receptors on B cells. The blockage of BLyS and APRIL interaction with their respective cell membrane receptors (transmembrane activator and CAML interactor [TACI], B-cell maturation antigen, and BLyS receptors) by telitacicept would inhibit B-cell proliferation and maturation. This suppression at the proximal portion of the immune response could alleviate autoimmune symptoms. This study is a randomized, double-blind, placebo-controlled Phase 3 study with an open-label extension to evaluate the efficacy and safety of telitacicept in a global patient population with gMG. ;
