About this 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

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

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

Secondary outcomes (2)
  1. Time to death (all causes) or to worsening of PFTs up to End-of-Study.

  2. 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

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Bosentan in people with Pulmonary Fibrosis and Scleroderma, Systemic, run by Actelion.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline to End-of-Study in 6-minute walk distance.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00070590, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Feb 2025.
