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.
