Summary
The purpose of this 3-period study is to confirm the efficacy and safety of batoclimab in participants with gMG. In Period 1, participants will be randomized 1:1:1 to receive batoclimab 680 milligrams (mg) subcutaneously (SC) once a week (QW) or 340 mg SC QW or placebo. The primary efficacy endpoint will be assessed by change in the myasthenia gravis activities of daily living (MG- ADL) score in acetylcholine receptor antibody seropositive (AChRAb+) participants. In Period 2, participants previously treated with batoclimab will be re-randomized to stay on batoclimab (340 mg SC QW or 340 mg SC every two weeks) or receive placebo treatment. The secondary endpoint of maintenance of efficacy will be assessed by change in the MG- ADL score in AChRAb+ participants. Participants demonstrating a response to batoclimab during either Period 1 or 2 may enter the long-term extension (Period 3).
