New drug combo shows promise in Hard-to-Treat breast cancer
NCT ID NCT03959891
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial is testing whether adding an experimental drug called Ipatasertib to standard hormone therapy can help control metastatic hormone receptor positive breast cancer. The study involves 77 women whose cancer has spread and is no longer responding to usual treatments. Researchers are primarily checking for safety and side effects, while also tracking how long the cancer stays under control.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Ipatasertib (an AKT inhibitor) combined with hormone therapies like fulvestrant or letrozole
- What this could lead to
- If it works, this could point toward a new treatment option for metastatic hormone receptor positive breast cancer that has stopped responding to standard therapies.
- What could go wrong
- This is an early Phase 1 trial with only 77 participants, so it is primarily testing safety. The drug may not shrink tumors or improve survival, and side effects could be significant.
