Optimizing the Use and Safety of ADCs in Metastatic Breast Cancer: Indications, Toxicity Profiles, and Proactive Management

As part of this performance and quality improvement initiative, Reshma L. Mahtani, D.O. reviews the latest clinical evidence, guideline recommendations, and emerging strategies to support the coordinated care of patients receiving antibody-drug conjugates (ADCs). Through expert-led presentations and case-based discussions, participants will explore approaches to optimizing ADC utilization across the continuum of care.

Healthcare professionals will gain practical strategies to improve interdisciplinary collaboration, recognize and manage ADC-related adverse events, and support timely interventions that enhance patient safety and treatment outcomes. This activity is designed to equip clinicians with actionable knowledge that can be applied directly in practice to deliver high-quality, patient-centered care for individuals receiving—or being considered for—ADC therapy.

Target Audience

Breast Medical Oncologists, Radiation Oncologists, Emergency Medicine Physicians, Infusion Nurses, Nurse Navigators, Advanced Practice Registered Nurses, Pharmacists, Pharmacy Technicians, Physician Assistants/Physician Associates, Pulmonologists, Radiologists, Schedulers, Medical Assistants, Patient Care Facilitators, and all personnel involved in the care of the breast cancer patient.

Learning Objectives

Upon completion of this conference, participants should be better able to:

  • Discuss indications of the different ADCs in metastatic breast cancer
  • Differentiate the toxicity profiles of datopotamab deruxtecan (Dato-DXd), sacituzumab govitecan, and trastuzumab deruxtecan (T-DXd) (fatigue, nausea, diarrhea, stomatitis, neutropenia).
  • Discuss evidence-based, proactive strategies to prevent and manage ADC-related adverse events, including antiemetic protocols, diarrhea management algorithms, growth factor use, oral care for stomatitis, and dose-modification approaches.
  • Discuss clinical and radiographic signs of ADC-associated ILD/pneumonitis and management.
