Treatment Patterns, Clinical Events, and Costs of Care for Patients With Triple Negative Metastatic Breast Cancer: A Retrospective US Claims Database Study

Our study focused on patients with mTNBC with the greatest unmet need, namely those ineligible for immunotherapy. In patients with mTNBC, most of whom received chemotherapy as standard of care, CEIs presented both a clinical and economic burden, highlighting the need for newer treatments that balance total costs of care with adverse events and clinical benefit.
