Experimental gene therapy targets rare muscle disease
NCT ID NCT05224505
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests a gene therapy called ATA-100 for people with LGMDR9, a rare genetic muscle disease that causes progressive weakness. Six adults receive a single intravenous infusion of the therapy, which delivers a working copy of the FKRP gene. The main goal is to check safety and tolerability over five years, with secondary measures looking at muscle function and breathing.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ATA-100 (a gene therapy that delivers a working FKRP gene via a harmless virus)
What this could lead to
If successful, this could point toward a treatment that slows or stops muscle weakening in people with LGMDR9.
What could go wrong
This is a very early, small Phase 1 trial with only 6 participants, so safety and dosing are still being tested. It may not lead to a working treatment, and gene therapies can sometimes cause immune reactions.
