About this trial
Acute respiratory distress syndrome (ARDS) is a severe form of acute lung injury and a major cause of Intensive Care Unit (ICU) admission worldwide. Despite a large number of randomized clinical trials, a specific and effective pharmacological approach for patients with ARDS is still lacking.
Fibroproliferation is a crucial part of the host defence response, and severe fibrotic lung disease affects ARDS patients even years after acute phase resolution.
Pirfenidone is an oral anti-fibrotic drug, approved and largely used for treatment of idiopathic pulmonary fibrosis (IPF). The effect of Pirfenidone in ARDS has been evaluated only in animal models.
This is a randomized controlled study to evaluate for the first time the efficacy of Pirfenidone in ARDS.
