- How to Read a Study Record
- To characterize the efficacy of reparixin in ameliorating lung injury and systemic inflammation and expediting clinical recovery and liberation from mechanical ventilation in adult patients with moderate to severe ARDS (PaO2/FIO2 ratio ≤ 200).
- To evaluate the safety of reparixin vs. placebo in patients enrolled in the study.
|Condition or disease||Intervention/treatment||Phase|
|Acute Respiratory Distress Syndrome, Adult||Drug: Reparixin 600mg Other: Matching Placebo||Phase 2|
Phase 2, randomized, double-blinded, placebo controlled, multicenter study. All patients will receive therapy in line with current standard-of-care as it pertains to ARDS management (protocolized ventilator management will be made available to all sites in accordance with currently accepted standard of care). Patients will be randomized (1:1) to either reparixin or placebo. Duration of treatment will be 14 days.
The study will consist of 4 study periods:
Screening Randomization and Baseline assessments, Treatment (14 days with discretionary extension up to 21 days), Follow-up (up to 28 days or hospital discharge, whichever occurs first, and then up to day-60).
|Study Type :||Interventional (Clinical Trial)|
