New pill aims to shrink Hard-to-Treat cancers
NCT ID NCT07029399
First seen Jun 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This early-stage trial tests an experimental oral drug called NKT5097 in adults with advanced solid tumors, especially breast cancer. The drug works by breaking down two proteins that help cancer cells grow. Researchers want to find the safest dose and see if it can shrink tumors, either alone or with other drugs.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- NKT5097 (oral tablet that degrades CDK2 and CDK4 proteins)
- What this could lead to
- If it works, this could lead to a new treatment option for advanced breast cancer and other solid tumors that have stopped responding to standard therapies.
- What could go wrong
- This is an early Phase 1 trial, so the drug may not be safe or effective. Side effects are unknown, and it will take years to know if it helps patients.
