Not yet recruiting This study
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 Results may not be published yet.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.

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

Researchers are testing whether a monthly injection of berobenatide can reduce the severity of obstructive sleep apnea and lower body weight in adults who have overweight or obesity and use a PAP breathing machine. The trial enrolls about 258 adults with moderate to severe sleep apnea. Participants receive either berobenatide or a placebo injection and attend sleep studies and health checks so researchers can compare the effects on breathing pauses, weight, and other health measures.

What this could mean

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

Active substance
berobenatide, an experimental once-monthly injectable drug
What this could lead to
If it works, this could offer a monthly injection that eases sleep apnea and supports weight loss for people who use a PAP machine.
What could go wrong
The drug is still experimental, and the trial may show it does not improve sleep apnea or weight enough to matter. Injections can cause side effects, and results in this group may not apply to everyone with sleep apnea.
