Summary

This phase II trial is testing whether patients with early HER2-positive or triple-negative breast cancer who had a complete response to pre-surgery treatment and have no cancer DNA in their blood can safely receive less therapy after surgery. The goal is to reduce side effects while keeping the cancer from coming back. The study involves 120 participants and uses drugs like pembrolizumab, trastuzumab, and pertuzumab.
