New hope for tough blood cancers? early trial launches
NCT ID NCT07572006
First seen Jun 25, 2026 · Last updated Aug 28, 2026 · Updated 4 times
Summary
This early-stage trial is testing an experimental drug called JNJ-95804306 in people with blood cancers like leukemia that have come back or not responded to standard treatments. The study has two parts: first, finding a safe dose, and then checking if the drug shrinks tumors when used alone or with standard care. About 280 participants will take part across multiple sites.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- JNJ-95804306
- What this could lead to
- If successful, this could point toward a new treatment option for people with blood cancers that have not responded to other therapies.
- What could go wrong
- This is an early Phase 1 trial, so the drug may not be effective or may cause serious side effects. It is also small and focused on safety, not proof of benefit.
