Compares treatment options for Generalized Myasthenia Gravis
Official title A Phase III Study to Investigate Efficacy, Safety and Tolerability of Iptacopan Compared With Placebo in Participants Aged 18 to 85 Years With gMG.
ClinicalTrials.gov ID: NCT06517758
What this study is testing
What is Iptacopan?
Iptacopan is an investigational medicine, given as a pill taken by mouth, being studied as a potential treatment for generalized myasthenia gravis.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study is a randomized, double-blind, placebo-controlled, multicenter, Phase III study, to evaluate efficacy, safety and tolerability of iptacopan in patients with AChR+ gMG who are on stable SOC treatment. Participants who meet the eligibility criteria will be randomized in a ratio of 1:1, to receive either iptacopan or matching placebo, for 6 months (180 days) while continuing on a stable SOC treatment.
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
