Promising drug cocktail aims to control aggressive breast cancer
NCT ID NCT06690840
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a combination of three drugs (atezolizumab, vinorelbine, and cyclophosphamide) in people with advanced triple-negative breast cancer that has spread. Participants have already received immunotherapy before. The goal is to see if this new mix can shrink tumors or slow the disease. About 45 people will take part.
