Infusion of iloprost for 72 hours in patients on mechanical ventilation with acute respiratory failure

Efficacy and Safety of 72-hour Infusion of Prostacyclin (1 ng/kg/Min) in Mechanically Ventilated Patients With Infectious Pulmonary Endotheliopathy - a Multicenter Randomized, Placebo-controlled, Blinded, Investigator-initiated Trial

Phase 2 Interventional Rigshospitalet, Denmark · NCT06319274

This study is testing if giving a medication called iloprost for 72 hours can help patients on mechanical ventilation with severe breathing problems caused by infections feel better and live longer.

What this trial studies

This clinical trial investigates the efficacy and safety of continuous intravenous administration of low-dose iloprost compared to a placebo in 450 mechanically ventilated patients suffering from acute respiratory failure due to infectious causes. The study aims to determine if iloprost can improve endothelial function and reduce all-cause mortality at day 28 by restoring vascular integrity in patients with significant endothelial damage. Eligible patients will be those requiring mechanical ventilation and exhibiting specific biomarkers indicative of endothelial dysfunction. The trial will last for 72 hours, during which patients will receive either iloprost or isotonic saline.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients aged 18 and older who are mechanically ventilated due to suspected pulmonary infections.

Not a fit: Patients with septic shock, severe heart failure, or those who have previously participated in similar trials may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce mortality rates in critically ill patients with acute respiratory failure.

How similar studies have performed: Previous studies have shown promising results with iloprost in improving endothelial function in similar patient populations, indicating potential for success in this trial.
