Efficacy and Safety of Oral Bosentan in Pulmonary Fibrosis Associated With Scleroderma - Full Text View

Sponsor:	Actelion
Information provided by:	Actelion
ClinicalTrials.gov Identifier:	NCT00070590

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.

Study Design:	Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study
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
