TARGET AUDIENCE
This program is intended for medical oncologists, breast surgeons, radiation oncologists and other healthcare professionals involved in the diagnosis and treatment of breast cancer.

LEARNING OBJECTIVES

• Evaluate published and emerging clinical research findings with TROP2-directed antibody-drug conjugates (ADCs) for HR-positive and triple-negative metastatic breast cancer (mBC), and consider the current and future 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 care of patients with mBC, and identify management and mitigation strategies.
• Recall ongoing trials evaluating investigational ADCs or novel strategies involving approved ADCs for mBC, and appropriately counsel patients regarding enrollment.
