New antibody drug shows promise in fighting advanced cancers
NCT ID NCT04452955
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 trial is testing an experimental drug called PRL3-zumab in 51 people with advanced solid tumors that cannot be removed by surgery or have spread. The drug is given as an IV infusion every two weeks. The main goal is to see how long the cancer stays under control and whether tumors shrink.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PRL3-zumab
- What this could lead to
- If successful, this could provide a new treatment option for people with advanced solid tumors that have not responded to other therapies.
- What could go wrong
- This is an early Phase 2 trial with only 51 participants, so results may not apply to all patients. The drug may not shrink tumors or improve survival, and side effects are still being studied.
