New drug cocktail aims to wipe out breast cancer before surgery

NCT ID NCT07245797

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests whether adding the drug inavolisib to a standard pre-surgery regimen (pertuzumab, trastuzumab, and nab-paclitaxel) can improve outcomes for people with a specific genetic mutation (PIK3CA) in HER2-positive early breast cancer. About 164 participants will receive either the combo with or without inavolisib before surgery. The main goal is to see if the cancer disappears completely by the time of surgery.

What this could mean

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

Active substance

inavolisib plus pertuzumab and trastuzumab (subcutaneous) and nab-paclitaxel

What this could lead to

If successful, this could point toward a more effective pre-surgery treatment for a specific type of breast cancer, potentially increasing the chance of no cancer remaining at surgery.

What could go wrong

This is a small, early-phase (phase 2) trial, so results may not confirm benefit. Adding inavolisib may also increase side effects without improving outcomes.
