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 Results may not be published yet.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

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 pirfenidone, a drug already used for a different lung disease, can prevent scarring in patients with severe acute respiratory distress syndrome (ARDS). About 130 people on ventilators will receive either pirfenidone or a placebo through a feeding tube. The goal is to see if the drug helps them spend fewer days on a ventilator and improves recovery.

What this could mean

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

Active substance
Pirfenidone
What this could lead to
If it works, this could provide a new treatment to prevent long-term lung damage in patients with severe respiratory failure.
What could go wrong
This is an early test in humans for ARDS, so the drug may not work as hoped. Side effects from pirfenidone, like nausea or liver issues, are possible.
