What is being measured

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

  1. Extent of Exposure to Bosentan in Patients With Idiopathic Pulmonary Fibrosis (IPF)

    Mean extent of exposure to bosentan treatment in months

    Measured: Start of study to end of study, up to 21 months

Secondary outcomes (4)
  1. Number of Patients Exposed to Bosentan Over Time

    Numbers of participants exposed to bosentan treatment over time

    Measured: Start to end of study, up to 21 months

  2. Adverse Events (AE) Leading to Discontinuation of Study Drug.

    Number of participants with at least one AE that led to permanent discontinuation of study treatment.

    Measured: Start to end of study, up to 21 months

  3. Treatment-emergent Serious Adverse Events (SAE)

    Number of participants with at least one SAE during the study.

    Measured: up to 21 months plus 28 days after the end of study drug

  4. Occurrence of Liver Function Test (LFT: Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST)) Abnormality.

    Number of participants with an increase in ALT and/or AST to > 3 times upper limit of normal during the study.

    Measured: up to 21 months, plus 24 hours after the end of study treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Bosentan in people with Idiopathic Pulmonary Fibrosis, 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?

The sponsor lists 3 inclusion and 5 exclusion criteria. 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 4 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 phase mean?

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?

Yes. Results are posted in the registry (first posted 3 Aug 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Extent of Exposure to Bosentan in Patients With Idiopathic Pulmonary Fibrosis (IPF) (time frame: Start of study to end of study, up to 21 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Feb 2025.
