Detailed Description

This study is a randomized, double-blind, placebo-controlled, multicenter, Phase III study, to evaluate the efficacy, safety and tolerability of remibrutinib in gMG patients who are on stable SOC treatment. Approximately 180 eligible participants will be randomized in a ratio of 1:1, to receive either remibrutinib or matching placebo. The study consists of a Core Part (6-months double-blind treatment) and an Extension Part (up to 60-month open-label treatment).
