Brief Summary:
The primary hypothesis was that early aspirin administration will decrease the rate of developing acute lung injury during the first 7 days after presentation to the hospital.

Condition or disease Intervention/treatment Phase
Acute Respiratory Distress Syndrome Drug: Aspirin Drug: Lactose powder Phase 2

Detailed Description:

Acute respiratory distress syndrome (ARDS) remains a life-threatening critical care syndrome characterized by alveolar-capillary membrane injury and hypoxemic respiratory failure. The median time to onset of ARDS is 2 days after hospital presentation. Therefore, the period between hospital presentation and the development of ARDS presents a brief window of opportunity for ARDS prevention.

This was a multicenter, double-blind, placebo-controlled, parallel-group, Phase 2b, randomized clinical trial. Development of ARDS was defined by Berlin criteria (modified to require invasive mechanical ventilation) within 7 days of hospital admission. The first dose of study drug or placebo was administered within 24 hours after presentation to the hospital. Important co-interventions were standardized across sites using a web-based tool, Checklist for Lung Injury Prevention. Study participants were screened daily for receipt of mechanical ventilation and determination of the partial pressure of arterial oxygen (PaO2) or oxygen saturation to fraction of inspired oxygen ratio (SpO2:FIO2). If the participant's SpO2:FIO2 ratio was consistently below 315, hypoxemia was confirmed with measurement of arterial blood gas. Chest radiographs for all intubated patients with a SpO2:FIO2 of 300 or less were independently reviewed by both site investigator and a member of the trial's executive committee. Study participants who died or were discharged from the hospital before day 7 without meeting criteria for ARDS were adjudicated as not having ARDS.

Primary Outcome Measures :
  1. Number of Participants Who Developed Acute Respiratory Distress Syndrome (ARDS) Within 7 Days [ Time Frame: Within seven days from hospital presentation ]
    ARDS was defined by Berlin criteria (modified to require invasive mechanical ventilation) within 7 days of hospital admission.

Secondary Outcome Measures :

  2. Number of Participants With ARDS or Mortality Within 7 Days [ Time Frame: within 7 days ]
  3. Number of Subjects With Mechanical Ventilation at Any Time During Hospitalization [ Time Frame: approximately 7 days ]
  4. Mean Number of Days Participants Were Ventilator-Free To Day 28 [ Time Frame: baseline, Day 28 ]
  5. Number of Subjects Admitted to Intensive Care Unit (ICU) [ Time Frame: 7 days ]
  6. Mean Hospital Length of Stay [ Time Frame: approximately 7 days ]
