New experimental drug BMS-986500 enters first human trials for advanced cancers
NCT ID NCT06997029
First seen Jun 25, 2026 · Last updated Jul 10, 2026 · Updated 3 times
Summary
This early-stage trial is testing an experimental drug called BMS-986500 in people with advanced solid tumors or breast cancer that has not responded to prior treatments. The study will first test the drug alone, then in combination with other cancer drugs (palbociclib and fulvestrant) for breast cancer patients. The main goals are to check safety, find the right dose, and see how the body processes the drug. About 234 participants are being recruited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BMS-986500 (an experimental drug)
- What this could lead to
- If successful, this could point toward a new treatment option for advanced solid tumors and breast cancer that has stopped responding to other therapies.
- What could go wrong
- This is a very early Phase 1 trial focused on safety and dosing, not effectiveness. The drug may not work or could have serious side effects. Results may not apply to all patients.
