ADAPT Forward master protocol testing multiple regimens for generalized myasthenia gravis

Official title: A Master Protocol for an Exploratory, Phase 2a, Proof-of-Concept Platform Study to Evaluate the Safety, Tolerability, and Efficacy of Multiple Regimens in Participants With Myasthenia Gravis

Run by argenx · NCT07294170 · Data updated 2026-11-12

This platform tests several drug regimens, including efgartigimod IV and empasiprubart IV, in adults with generalized myasthenia gravis to find safer and more effective treatment combinations.

Is this trial a fit for you?

Likely a good fit

Adults (at least 18 years old) with clinician-diagnosed generalized myasthenia gravis who are stable on background MG therapies are the intended participants.

Probably not a fit

People with other autoimmune diseases or unstable medical conditions, or those who are MGFA Class V, are unlikely to benefit or be eligible for participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

ADAPT Forward uses a single master protocol that lets multiple intervention-specific appendices (ISAs) run under the same overall framework. The design includes a common master screening period, ISA-specific screening, an ISA treatment period of variable duration and design, and ISA safety follow-up periods. The initial ISA will test empasiprubart IV as an add-on to efgartigimod IV in AChR-antibody positive participants with a partial response to efgartigimod. Sites in California, Florida, and Maryland will follow ISA-specific procedures for enrollment, treatment, and follow-up.

Why it matters

Potential benefit: If successful, the program could identify treatment combinations that reduce symptoms and side effects and improve quality of life for people with generalized myasthenia gravis.

How similar studies have gone: FcRn-targeting agents such as efgartigimod have shown benefit in gMG in prior trials, but using empasiprubart as an add-on within this platform is a relatively novel approach.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Is at least 18 years of age and the local legal age of consent for clinical studies
* Has been diagnosed with MG with consistent clinical features per the investigator's clinical judgment
* If receiving MG therapy, including nonsteroidal immunosuppressive drugs (NSIDs), corticosteroids, or acetylcholinesterase (AChE) inhibitors either in combination or alone, the participant should receive a stable dosage before master protocol screening

Exclusion Criteria:

* Known autoimmune disease or any medical condition other than the indication under study that would interfere with an accurate assessment of clinical symptoms of MG or puts the participant at undue risk
* Is MGFA (Myasthenia Gravis Foundation of America) Class V
