New drug cocktail targets Hard-to-Treat cancers
NCT ID NCT06618287
First seen Jun 25, 2026 · Last updated Sep 15, 2026 · Updated 9 times
Summary
This study tests a new drug called BMS-986507, alone or with other cancer medicines, in adults with advanced lung or breast cancer that has spread. The goal is to check safety, side effects, and how well the drugs work. About 416 participants will receive different combinations to find the best dose.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BMS-986507 (also called Iza-bren or Izalontamab brengitecan) combined with other drugs like osimertinib, pembrolizumab, nivolumab, or pumitamig
- What this could lead to
- If successful, this could point toward new treatment options for people with advanced lung or breast cancer that has not responded to other therapies.
- What could go wrong
- This is an early-phase trial (phase 1/2a) with a small number of participants, so the main goal is safety, not proof of effectiveness. The combinations may cause side effects or fail to shrink tumors.
This is an AI summary of the original study and may miss details. Read our disclaimer.
