Can a Four-Drug combo erase Triple-Negative breast cancer before surgery?
NCT ID NCT06910072
First seen Aug 13, 2026 · Last updated Aug 19, 2026 · Updated 3 times
Summary
This trial is testing whether combining chemotherapy with two immunotherapy drugs, given before surgery, can completely eliminate triple-negative breast cancer in people with stage II-III disease. Participants will receive six cycles of the combination, and the main goal is to see how many achieve a pathological complete response (no cancer cells left in the removed tissue). The study also tracks side effects and long-term outcomes like event-free survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A combination of chemotherapy (paclitaxel polymeric micelles and carboplatin) and two immunotherapy drugs (iparomilimab and tuvonralimab) given before surgery.
- What this could lead to
- If successful, this approach could increase the chance of eliminating the tumor before surgery, potentially improving long-term outcomes for people with triple-negative breast cancer.
- What could go wrong
- This is an early-phase study with a small number of participants, so results may not be conclusive. The combination may cause significant side effects, and the benefit over standard treatment is not yet proven.
