Treatment of Acute Respiratory Distress Syndrome with Sivelestat Sodium

Efficacy of Sivelestat Sodium in the Treatment of ARDS With SIRS, a Multicenter Double-blind Randomized Controlled Clinical Trial

Phase 4 Interventional Sichuan Provincial People's Hospital · NCT04909697

This study is testing if a new medication called sivelestat sodium can help patients with Acute Respiratory Distress Syndrome and Systemic Inflammatory Response Syndrome by protecting their lungs from damage.

What this trial studies

This clinical trial evaluates the efficacy of sivelestat sodium, a specific inhibitor of neutrophil elastase, in treating patients with Acute Respiratory Distress Syndrome (ARDS) who also have Systemic Inflammatory Response Syndrome (SIRS). The study aims to prevent lung tissue injury caused by the inflammatory cascade associated with ARDS. It is a multicenter randomized controlled trial designed to provide robust evidence on the effectiveness of this treatment approach. Participants will receive either sivelestat sodium or saline as a control.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 who meet the Berlin diagnostic criteria for ARDS and have specific oxygenation levels.

Not a fit: Patients with chronic respiratory diseases, single cardiogenic pulmonary edema, or those with a poor prognosis are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients suffering from ARDS by reducing lung injury.

How similar studies have performed: While previous observational studies have shown promise for sivelestat sodium, this is one of the first prospective multicenter randomized controlled trials evaluating its efficacy in ARDS.
