Trial Summary

What is the purpose of this trial?

The DUAL-2 study is designed as a multicenter, double-blind two-period study with an initial fixed 16-week Period 1, followed by a Period 2 of variable duration. All patients completing Period 1 continue on their original randomized treatment into Period 2, until the last randomized patient has completed Period 1. Patients are randomized in a 1:1:1 ratio (macitentan 3mg: macitentan 10mg: placebo). The primary objective is to demonstrate the effect of macitentan on the reduction of the number of new digital ulcers in patients with systemic sclerosis and ongoing digital ulcers (DU). Other objectives include: * the evaluation of the efficacy of macitentan on hand functionality and DU burden at Week 16 in SSc patients with ongoing DU disease. * the evaluation of the safety and tolerability of macitentan in these patients. * the evaluation of the efficacy of macitentan on time to first DU complication during the entire treatment period.
