NCT ID NCT04841148

First seen Apr 14, 2026 · Last updated Apr 26, 2026 · Updated 4 times

Summary

This study tests whether adding a drug called palbociclib to either hydroxychloroquine or avelumab can eliminate dormant breast cancer cells hiding in the bone marrow. These cells can cause cancer to return years later. The trial involves 96 people with early-stage ER+ breast cancer who still have these hidden cells after standard treatment. The goal is to see if these combinations can clear the cells and reduce the risk of recurrence.
