Summary

This study tested a single dose of a gene therapy called PF-06939926 in 23 people with Duchenne muscular dystrophy (DMD), both those who could still walk and those who could not. The main goal was to check safety and side effects over one year. The trial was stopped early, but researchers looked at how well the therapy was tolerated and measured changes in muscle strength and function.
