What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers compare the Trilogy ventilator, a portable breathing machine, with conventional mechanical ventilators in people who need breathing support. Participants use each device for one hour while set to their usual breathing mode and prescription settings. The study measures blood gas levels and oxygen saturation to see whether the Trilogy delivers similar breathing support. This small trial includes 11 adults who are clinically stable and require ventilation through a mask or tube.

What this could mean

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

Active substance
Trilogy portable ventilator
What this could lead to
If the Trilogy device matches conventional ventilators, it could offer a more portable option for people who need breathing support outside a hospital.
What could go wrong
This is a small study of 11 people, so the results may not apply to everyone. Participants must be clinically stable, and the short one-hour testing period may not reflect long-term use.
