Clinical Trial Summary

In an earlier clinical trial, RAPIDS-1, conducted in scleroderma patients with or without digital ulcers at baseline, bosentan significantly reduced the number of new digital ulcers versus placebo. The purpose of the present trial (RAPIDS-2) is to evaluate the prevention and healing effects of bosentan versus placebo on digital ulcers over a 24-week treatment period.
