  Purpose
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.

Condition Intervention Phase
Pulmonary Fibrosis Scleroderma, Systemic Drug: Bosentan Phase 2 Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Placebo-controlled, Multicenter Study to Assess the Efficacy, Safety and Tolerability of Bosentan in Patients With Interstitial Lung Disease Associated With Systemic Sclerosis

Primary Outcome Measures:
  • Change from baseline to End-of-Study in 6-minute walk distance.

Secondary Outcome Measures:
  • 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

Estimated Enrollment: 132
Study Start Date: July 2003
Study Completion Date: September 2005
Primary Completion Date: September 2005 (Final data collection date for primary outcome measure)
