Optimizing the Management of Metastatic Triple-Negative Breast Cancer — Webinar Proceedings

Faculty

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

LEARNING OBJECTIVES

• Evaluate published research findings, clinical factors (eg, PD-L1, HER2 and BRCA status) and individual preferences in the selection and sequencing of available therapeutic agents and strategies for patients with metastatic triple-negative breast cancer (mTNBC).
• Review published research data supporting the use of TROP2-targeted antibody-drug conjugate (ADC) therapy in combination with anti-PD-1/PD-L1 antibodies for patients with newly diagnosed mTNBC, and use this information to make appropriate treatment recommendations.
• Assess recently presented clinical research findings with TROP2-directed ADC monotherapy as first-line treatment for mTNBC, and optimally incorporate these agents into the care of patients with this disease.
• Understand the biological rationale for the evaluation of HER2-directed ADCs for patients with HER2-low mTNBC, and identify patients for whom treatment with this approach would be appropriate.
• Recognize the spectrum, frequency and severity of treatment-emergent adverse events associated with agents and approaches commonly used for mTNBC, and develop strategies to monitor for, prevent and manage these complications.
• Assess the mechanisms of action of, early data with and ongoing clinical trials evaluating other novel agents and treatment strategies under development for mTNBC.
