NCT ID NCT05660083

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

Summary

This phase 2 trial is testing a combination of three drugs—alpelisib, L-NMMA, and nab-paclitaxel—in people with a rare, aggressive form of breast cancer called metaplastic breast cancer (MpBC) that has spread or is locally advanced. The study aims to find the best dose and see if the combo can shrink tumors. About 36 adults whose cancer is HER2-negative and has not responded to prior treatments will participate.

Active substance

alpelisib, L-NMMA (iNOS inhibitor), and nab-paclitaxel

What this could lead to

If successful, this could offer a new treatment option for people with a rare and aggressive form of breast cancer that has not responded to standard therapies.

What could go wrong

This is a small, early-phase trial (36 people) testing a combination of drugs, so results may not apply widely. Side effects like high blood sugar, blood clots, and high blood pressure are possible.
