Overview
Brief Summary
To evaluate the efficacy and safety of trilaciclib combined with standard treatment project as a neoadjuvant treatment for triple negative breast cancer
Detailed Description
Trilaciclib indication: Trilaciclib, a CDK4/6 inhibitor, was used before chemotherapy to reduce the incidence of bone marrow suppression and approved by the FDA for small cell lung cancer patients in 2021.
