Optimizing the Integration of ADCs into the Treatment of HR-Positive and Triple-Negative Metastatic Breast Cancer — Video Lecture

Faculty

TARGET AUDIENCE
This activity is intended for medical oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of breast cancer.

LEARNING OBJECTIVES

• Evaluate published clinical research findings with TROP2-directed antibody-drug conjugates (ADCs) for HR-positive and triple-negative metastatic breast cancer (mBC), and consider the current role of these agents in patient care.
• Assess the biological rationale for the evaluation of HER2-directed ADCs for patients with HER2-low and HER2-ultralow mBC, and optimally integrate FDA-approved agents into clinical algorithms.
• Discern the side effects and toxicities associated with FDA-approved ADCs in the treatment of mBC, and identify strategies to manage and mitigate them.
• Recall ongoing trials evaluating investigational ADCs or novel strategies involving approved ADCs for mBC, and appropriately counsel patients regarding enrollment.
