New drug aims to build muscle in rare muscular dystrophy

NCT ID NCT07435129

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 2 study tests a drug called apitegromab in 60 adults with facioscapulohumeral muscular dystrophy (FSHD), a genetic condition that causes muscle weakness. Participants will receive either the drug or a placebo every 4 weeks for a year. The main goal is to see if the drug increases total lean muscle volume, with a secondary focus on muscle function and safety.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

apitegromab (a lab-made antibody that blocks a protein called myostatin, which limits muscle growth)

What this could lead to

If it works, this could point toward a treatment that helps people with FSHD build and maintain muscle, slowing the disease's progression.

What could go wrong

This is an early Phase 2 trial with only 60 people, so results may not apply to everyone. The main goal is muscle volume, not yet proven to improve daily life. Side effects from the IV infusions are possible.
