Run by University Hospital Tuebingen · NCT04208126 · Data updated 2026-11-12

This study is testing whether starting ECMO treatment right away or waiting to see if other treatments work first is better for people with severe respiratory failure caused by ARDS.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have been diagnosed with severe ARDS within 96 hours of symptom onset.

Probably not a fit

Patients who are not committed to full intensive care support or those who are pregnant will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial is a prospective randomized multicenter trial that investigates the timing of Extracorporal Membrane Oxygenation (ECMO) treatment in patients with Acute Respiratory Distress Syndrome (ARDS). Patients will be assigned to receive ECMO immediately upon admission to the intensive care unit or to undergo conservative treatment initially, with ECMO as a rescue option if conservative therapy fails. The study aims to enroll patients within 24 hours of ARDS symptom onset and will follow them for 90 days to assess outcomes such as mortality and organ failure scores.

Why it matters

Potential benefit: If successful, this study could improve survival rates and quality of life for patients with severe ARDS.

How similar studies have gone: Previous studies have explored ECMO in ARDS, but this specific timing comparison is novel and has not been extensively tested.
