Key clinical point: Sacituzumab govitecan (SG) was more effective than chemotherapy in improving progression-free survival (PFS) and showed a manageable safety profile in patients with heavily pretreated, endocrine-resistant, hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2−) advanced breast cancer (BC).
Major finding: SG vs chemotherapy significantly improved PFS (hazard ratio [HR] 0.66; P = .0003), with PFS rates being 46% vs 30% at 6 months and 21% vs 7% at 12 months, respectively. The most common grade ≥3 treatment-related adverse events with SG vs chemotherapy were neutropenia (51% vs 38%) and diarrhea (9% vs 1%).
Study details: Findings are the primary results of the phase 3 TROPiCS-02 trial including 543 patients with HR+/HER2− locally recurrent inoperable/metastatic BC who had received prior cyclin-dependent kinase 4/6 inhibitor with 2-4 lines of chemotherapy and were randomly assigned to receive SG or chemotherapy.
Disclosures: This study was supported by Gilead Sciences Inc. Four authors declared being employees of or stockowners in Gilead Sciences. The other authors reported ties with several sources, including Gilead.
