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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tested a new weekly injection called UBT251 in 205 overweight or obese adults to see if it helps with weight loss. Participants received different doses of the drug or a placebo for 24 weeks. The main goal was to measure the percentage change in body weight, with additional checks on waist size, BMI, and blood fats. The trial is now complete, and results will help decide if larger studies are needed.

What this could mean

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

Active substance
UBT251 injection (a weekly shot for weight loss)
What this could lead to
If successful, this could lead to a new weekly injection option for managing obesity and related health issues like high blood pressure or fatty liver.
What could go wrong
This is an early Phase 2 study with only 205 people, so results may not apply to everyone. The drug may cause side effects or fail to show meaningful weight loss compared to placebo.
