Antibody Drug Conjugates in Hormone Receptor Positive Disease – ASCENT-07 and Beyond

Panelists discuss how results from antibody-drug conjugate trials, including those that fail primary endpoints, provide critical insights for refining sequencing strategies in hormone receptor–positive disease.

In this section, Dr. Traina and the panel review first-line ADCs, specifically the ASCENT-07 trial investigating sacituzumab govitecan versus standard chemotherapy in metastatic hormone receptor-positive breast cancer. The results did not meet prespecified efficacy endpoints for progression-free survival, but insightful subgroup and secondary analysis provide value, enhancing understanding of ADC sequencing. Panelists discuss the importance of target selection (HER2 vs. Trop-2) in ADC efficacy, highlight differing responses in hormone receptor vs. triple negative disease, and emphasize how real-world drug access post-progression influences trial data interpretation. Lessons from negative trials are recognized as equally critical as positive data, providing guardrails for future therapy sequencing.
