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 Results may not be published yet.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 tests whether awake patients with acute breathing failure who lie face down (prone positioning) for at least 10 hours a day for 3 days are less likely to need a breathing tube or die within 28 days, compared to standard care. The trial will include 342 intensive care unit patients with pneumonia-related breathing failure in Germany. The goal is to see if this simple, low-cost technique can improve outcomes.

What this could mean

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

Active substance
Awake prone positioning (lying face down while awake)
What this could lead to
If it works, this could provide a simple, low-cost way to help patients with respiratory failure avoid needing a breathing tube and reduce the risk of death.
What could go wrong
This is a relatively early study (Phase NA) and previous evidence is mostly from COVID-19 patients. It may not work for other causes of respiratory failure, and lying face down can be uncomfortable or difficult for some patients.

Inclusion Criteria: * The focus of this trial is to treat patients with respiratory failure. The inclusion criteria are selected accordingly. Patients meeting all of the criteria listed below will be included in the study: * Patients in the intensive care unit * High possibility of Pneumonia (community-acquired pneumonia or hospital-acquired pneumo-nia) either diagnosed by chest x-ray or computed tomography or clinically diagnosed at least with one of the following signs * Appearance of purulent secretions or changes in characteristics (color, odor, quantity, consistency) * Cough or dyspnea or tachypnea * Evocative auscultation * Presence of acute hypoxemic respiratory failure (PaO2/FIO2 ≤ 300 mmHg or SpO2/FiO2 ≤ 315) Exclusion Criteria: * Patients are excluded from the study if any of the following criteria are met at screening or before ran-domization, a detailed list is shown in the study manual: * Age below 18 * Pregnant woman * Patient is unlikely/unable to awake prone positioning, or to be compliant as indicated by the treating team * Prolonged need (≥ 4 days) for HFNO, NIV or CPAP before study inclusion * Urgent need for endotracheal intubation * Invasive Mechanical Ventilation * Shock o Defined as need for vasopressor ≥ 0.4 mcg/kg/min to maintain a mean blood pressure of ≥ 65 mmHg or systolic blood pressure ≥ 90 mmHg * Participation in another clinical interventional trial in the last 3 months * Previous Participation in the PROSA Trial * Long-term oxygenation therapy (LTOT) or continuous positive airway pressure (CPAP) therapy before hospital admission * Treatment
