BACKGROUND: Pulmonary fibrosis is a major complication of the Acute Respiratory Distress Syndrome (ARDS). Pirfenidone is an approved treatment for idiopathic pulmonary fibrosis. It may attenuate ARDS-related fibrosis and decrease the need for prolonged ventilation. Accordingly, we aimed to evaluate the effect of pirfenidone on ventilator-free days in patients with ARDS. METHODS: In a multi-center, randomized, double-blind, placebo-controlled trial, we plan to randomly assign 130 adults invasively ventilated for ARDS to receive pirfenidone or placebo for up to 28 days. The primary outcome is days alive and ventilator free at 28 days. Secondary outcomes include ICU-free days, hospital free days all at 28 day, ICU mortality and hospital mortality. We will also assess fibroproliferative changes on high-resolution CT scans at ICU discharge and quality of life. Data analysis will be on an intention-to-treat basis. DISCUSSION: The trial is ongoing and currently recruiting. It will be the first randomized controlled study to investigate whether, compared to placebo, pirfenidone increases the number of days alive and ventilator-free in patients with ARDS. Its double-blind multicenter design will provide internal validity, minimal bias, and a degree of external validity. If our hypothesis is confirmed, this treatment would justify larger trials of this intervention. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov with the trial identification NCT05075161.
