New drug cocktail targets Hard-to-Treat breast cancer

NCT ID NCT07405801

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial is testing whether adding a drug called inavolisib to two standard treatments (ribociclib and fulvestrant) can shrink tumors or slow cancer growth in people with advanced hormone-receptor-positive, HER2-negative breast cancer that has a specific genetic change (loss of chromosome 8p) but no PIK3CA mutation. About 80 participants will be randomly assigned to receive either the three-drug combo or a placebo plus the two standard drugs. The study is currently recruiting.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

inavolisib, ribociclib, and fulvestrant

What this could lead to

If successful, this could offer a new targeted treatment option for people with a specific type of advanced breast cancer that has stopped responding to hormone therapy.

What could go wrong

This is an early phase 2 trial with only 80 participants, so results may not apply to everyone. The combination may cause side effects or fail to improve outcomes compared to standard care.
