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 Results may not be published yet.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

Summary

This study tests an experimental drug called GSK5764227, given alone or with other treatments, in 320 people with advanced gastrointestinal cancers that have not responded to prior therapy. The main goal is to see if the drug can shrink tumors and how safe it is. It is an early-stage trial, so results will help determine if larger studies are warranted.

What this could mean

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

Active substance
GSK5764227 (an experimental biologic drug)
What this could lead to
If successful, this could point toward a new treatment option for people with advanced gastrointestinal cancers that have stopped responding to prior therapies.
What could go wrong
This is an early-phase trial (Phase 1/2) with a small number of participants, so the drug may not work as hoped or could have unexpected side effects. Results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
