New study tracks bone safety of DMD drug vamorolone over years
NCT ID NCT06713135
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows about 80 boys with Duchenne muscular dystrophy who have already taken vamorolone in earlier studies. Researchers want to see how safe the drug is over a longer time, especially its effect on bone health, like spine fractures. The boys continue taking vamorolone while doctors monitor them for side effects and fractures.
