New cancer drug injected into tumors shows promise in early trial
NCT ID NCT07395258
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests a new drug called BI 3923948, given as injections into the tumor, either alone or with a checkpoint inhibitor (ezabenlimab) given by IV. It includes about 60 adults with advanced solid tumors that have spread and are not responding to other treatments. The main goal is to find a safe dose and see if the combination can shrink tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BI 3923948 (injected into the tumor) and ezabenlimab (a checkpoint inhibitor given by IV)
- What this could lead to
- If it works, this could point toward a new treatment option for advanced solid tumors that have not responded to other therapies.
- What could go wrong
- This is a very early Phase 1 trial with only 60 participants, so the drug may not work or could have serious side effects. The trial is currently suspended, which adds uncertainty.
