First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests a combination of two drugs—entinostat and oral paclitaxel—in 50 people with HR-positive, HER2-negative advanced breast cancer who have already tried 2 to 4 prior treatments. The goal is to see if the combo can delay cancer growth. Participants take both drugs by mouth, and the study measures how long they live without the disease getting worse.
