Full description

All patients enrolled should suffer from moderate to severe skin fibrosis at the screening stage. The study period is 52 week. The study contains two stages, a 24-week blind stage following with open stage for another 24-week period of time. Subjects will receive pirfenidone or placebo randomized in the first 24-week and will all receive pirfenidone treatment in the second 24-week, with of combination of low dose steroids.
