Being tested
Matching Placebo, N-acetylcysteine, Pirfenidone
Medical subject headings
Idiopathic Pulmonary Fibrosis

What is being measured

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

  1. Percentage of Participants With Dose Reductions

    Percentage of participants with dose reductions in N-Acetylcysteine and placebo cohorts during the 24-week treatment period.

    Measured: From baseline up to 24 weeks

  2. Percentage of Participants With Early Treatment Discontinuations

    Percentage of participants with early treatment discontinuations in N-Acetylcysteine and placebo cohorts during the 24-week treatment period.

    Measured: From baseline up to 24 weeks

  3. Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs)

    An adverse event (AE) is defined as any untoward medical occurrence in a participant who is administered a study treatment regardless of whether or not the event has a causal relationship with the treatment. An AE, therefore, could be any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the study treatment, whether or not related to the treatment.

    Measured: Until 28 days from last dose of study treatment (Week 28)

  4. Percentage of Participants With Treatment-Emergent Serious Adverse Events (SAEs)

    A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose results in death, is life threatening, requires hospitalization or prolongation of hospitalization, or results in disability/incapacity, or congenital anomaly/birth defect.

    Measured: Until 28 days from last dose of study treatment (Week 28)

  5. Percentage of Participants With Treatment-Emergent Adverse Events Resulting in Permanent Discontinuation of Study Treatment

    Measured: Until 28 days from last dose of study treatment (Week 28)

  6. Percentage of Participants With Treatment-Emergent Deaths of All Causes

    Measured: Until 28 days from last dose of study treatment (Week 28)

  7. Percentage of Participants With Treatment-Emergent Adverse Events That Led to Dose Reduction or Temporary Discontinuation of Study Treatment

    Measured: Until 28 days from last dose of study treatment (Week 28)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing N-acetylcysteine and Pirfenidone in people with Idiopathic Pulmonary Fibrosis, run by Hoffmann-La Roche at 69 sites in 8 countries.

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 5 inclusion and 14 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 20 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 69 sites in Germany, France, Italy, United Kingdom, Sweden and 3 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 20 May 2016). 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?

Percentage of Participants With Dose Reductions (time frame: From baseline up to 24 weeks). The study lists 7 primary outcomes in all. 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 20 May 2016.
