NCT00070590

Brief Summary

Clinical and experimental studies suggest that bosentan could delay the progression of interstitial lung disease (ILD) associated with systemic sclerosis (SSc), a condition for which no established efficacious treatment is available. The present trial investigates a possible use of oral bosentan, which is currently approved for the treatment of symptoms of pulmonary arterial hypertension (PAH) WHO Class III and IV, to a new category of patients suffering from ILD associated with SSc.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline to End-of-Study in 6-minute walk distance.

Secondary Outcomes (2)

  • Time to death (all causes) or to worsening of PFTs up to End-of-Study.

  • Worsening of PFTs (on 2 consecutive tests at least 4 weeks apart) is defined as: decrease from baseline ≥ 10% in FVC OR decrease from baseline ≥ 15% in DLco AND ≥ 6% in FVC
