Overview
This study aims to assess safety and effectivness of long-term treatment with vamorolone in boys with Duchenne Muscular Dystrophy (DMD) who have completed prior studies with vamorolone.
Description
All subjects in this study have completed previous studies with vamorolone and continued to receive vamorolone under special programs: Compassionate Use Program [CUP], Named Patient Program [NPP] or Expanded Access Protocol [EAP]. All subjects will continue treatment with vamorolone under Guardian protocol instead. The primary objective of this study is to evaluate the safety of long-term treatment with vamorolone in boys with Duchenne Muscular Dystrophy regarding vertebral fractures. Secondary study objectives will evaluate the safety of long-term treatment with vamorolone on non-vertebral fractures, cataracts, delayed puberty, overall safety as well as ambulatory and non-ambulatory function.
