ADAPT Forward 2 - ISA2 - a Study to Evaluate the Safety, Tolerability and Efficacy of Empasiprubart IV Monotherapy in Participants With AChR-Ab Seropositive Generalized Myasthenia Gravis (ADAPT Forward2)
ISA2 to Master Protocol ARGX-999-2-MG-2000 - an Exploratory, Phase 2a, Randomized, Double-Blinded, Placebo-Controlled Study to Evaluate the Safety, Tolerability, and Efficacy of Empasiprubart IV Monotherapy in Participants With AChR-Ab Seropositive Generalized Myasthenia Gravis
This study is part of the ADAPT Forward platform study (NCT07294170). ADAPT Forward is a platform study with the aim to look at how safe different drugs are and how well they work for people with myasthenia gravis. The goal is to find the best therapeutic approach to reduce patients' side effects and improve their quality of life.
The aim of this ISA2 is to investigate the effects of empasiprubart in participants with AChR-Ab seropositive generalized myasthenia gravis (gMG).
The ADAPT Forward master protocol is registered on https://clinicaltrials.gov/study/NCT07294170

調査の概要
状態
詳細な説明
Once the master protocol and ISA2 screening periods are completed, eligible participants will be randomized to receive empasiprubart IV or placebo in the double-blinded treatment period (DBTP). All participants will then receive open-label efgartigimod PH20 SC PFS in the safety follow-up period.
The study duration for each participant is approximately up to 45 weeks.
