What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compares two oxygen therapy strategies for adults in the ICU with severe breathing failure. One group gets high-flow oxygen alone, the other gets high-flow oxygen plus CPAP sessions. The goal is to see if adding CPAP reduces the need for a breathing tube and lowers the risk of death within 90 days. About 1,084 participants will be enrolled.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Continuous positive airway pressure (CPAP) and high-flow nasal cannula oxygen therapy
What this could lead to
If it works, this could show that adding CPAP to high-flow oxygen helps more people survive severe breathing failure without needing a breathing tube.
What could go wrong
This is a large trial, but earlier studies on CPAP for this condition have had mixed results. The treatment may not lower death rates and could cause discomfort or delays in needed intubation.

Inclusion Criteria: 1. Adults (≥ 18 years old) 2. Admitted in the ICU for ≤ 24 hours 3. De novo hARF defined by the three following criteria: 1. Respiratory rate \> 25 breaths/min or signs of respiratory distress such as labored breathing or paradoxical inspiration 2. PaO2/FiO2 ≤ 200 mmHg under HFNC with flow ≥ 45 L/min, actual FiO2 being considered. 3. Uni or bilateral pulmonary infiltrate on chest X-ray or CT scan 4. Informed consent from the patient or her/his next of kin or another substitute decision maker, or inclusion procedure in emergency if the patient is unable to consent Exclusion Criteria: 1. Refusal of study participation by the patient or the proxy 2. Anatomical factors precluding the use of a nasal cannula or CPAP 3. Long term oxygen 4.

Known pregnancy or breastfeeding 8. Absence of coverage by the French statutory health care insurance system (including AME) 9. Abdominal, thoracic or cardiac surgery within the last 6 days 10. Use of vasopressors (norepinephrine\>0.3 mcg/kg/min) 11. Glasgow coma scale \< 13 12. Urgent need for endotracheal intubation 13. Patients at an end-of-life stage receiving compational oxygenation 14. Exacerbation of a chronic respiratory disease 15. Legal protection (curatorship or tutorship) 16. Undrained pneumothorax
