Researchers are evaluating nipocalimab, a drug given intravenously or subcutaneously, for adults with generalized myasthenia gravis gMG, a condition causing muscle weakness. This Phase 3 study aims to compare the effectiveness and safety of nipocalimab against a placebo and to understand how the drug works in the body when given by injection under the skin versus through a vein. The study includes a subcutaneous substudy to explore these differences in delivery methods. Participants receive nipocalimab intravenous infusions every two weeks for up to 24 weeks during a double-blind placebo-controlled phase. Those completing this phase can enter an open-label extension, choosing to continue receiving intravenous nipocalimab or switch to the subcutaneous form given weekly for eight weeks, with the option to continue longer in a long-term extension. Placebo is also given intravenously every two weeks in the control group during the double-blind phase. Throughout the study, participants undergo regular assessments including muscle function scores, quality of life evaluations, and blood tests measuring antibody levels and drug concentration. Researchers monitor safety by tracking adverse events and changes in clinical and laboratory parameters. The study measures changes in activities of daily living related to myasthenia gravis over time. Participation may last several years, as long-term monitoring continues after the initial treatment phases to evaluate ongoing effects and safety.

Researchers are evaluating the efficacy, safety, and tolerability of remibrutinib compared to a placebo in adult patients with Generalized Myasthenia Gravis gMG who are already on stable standard-of-care treatments. This multicenter Phase III study is randomized, double-blind, and placebo-controlled, aiming to provide important information about remibrutinibs impact on gMG symptoms. Participants will be randomly assigned to one of two groups one receiving remibrutinib tablets orally, and the other receiving matching placebo tablets, both during a 6-month core treatment period. Following this, participants can join an extension phase lasting up to 60 months, where all will receive open-label remibrutinib tablets orally. During the study, participants will undergo various assessments to monitor their symptoms and quality of life, including the Myasthenia Gravis Activity of Daily Living MG-ADL score and other clinical scales. Safety and tolerability will also be closely observed throughout the core and extension periods. The total duration of participation may extend up to nearly six years, including both study phases.

Researchers are evaluating the effectiveness and safety of a new oral cladribine formulation in adults with Generalized Myasthenia Gravis gMG. This phase 3 clinical trial compares cladribine to a placebo to understand its sustained benefits, the need for retreatment, and long-term safety. The study also includes a component to analyze how the drug is processed in the body and features interviews to learn about participants experiences with cladribine treatment. The trial is organized into three periods a double-blind placebo-controlled DBPC period where participants receive either placebo or cladribine in two separate oral courses a blinded extension BE period where initial placebo recipients switch to cladribine doses and some receive retreatment if needed and a retreatment RT period where participants may receive additional cladribine or placebo based on clinical need. Doses include low and high oral cladribine, administered as scheduled treatment courses. Participants will undergo various assessments including evaluations of muscle weakness and daily living activities using specific scales like the MG-ADL and QMG. Researchers will monitor safety through tracking adverse events, laboratory tests, and heart monitoring. Pharmacokinetic blood sampling will measure cladribine levels at multiple time points. The study duration extends up to week 144, during which participants responses and safety are closely observed to understand the drugs effects over time.
