New hope for stomach and bowel cancers? experimental drug enters human trials
NCT ID NCT06885034
First seen Jun 26, 2026 · Last updated Aug 04, 2026 · Updated 5 times
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.
