New drug combo shows promise in early cancer trial
NCT ID NCT04649385
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tested a new drug called BGB-15025, alone or with another drug (tislelizumab), in 157 people with advanced solid tumors that had stopped responding to standard treatments. The main goal was to check safety and find the best dose. The study is now complete, and results will help guide future research.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BGB-15025 (HPK1 inhibitor) and tislelizumab (anti-PD-1 antibody)
- What this could lead to
- If successful, this could lead to a new treatment option for advanced solid tumors that have stopped responding to standard therapies.
- What could go wrong
- This is an early Phase 1 trial focused on safety and dosing, so it is too soon to know if the drug works. Side effects are possible, and the drug may not shrink tumors.
