Trodelvy OK’d for Pre-treated Metastatic Breast Cancer
FDA has approved a Gilead Sciences supplemental BLA for Trodelvy (sacituzumab govitecan-hziy) for treating adult patients with unresectable locally advanced or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer who have received endocrine-based therapy and at least two additional systemic therapies in the metastatic setting. Approval was based on results from the Phase 3 TROPiCS-02 study that showed “statistically significant and clinically meaningful progression-free survival and overall survival data,” the company says. “Three times as many people treated with Trodelvy were progression free at one year versus those treated with chemotherapy (21% versus 7%).”
Gilead says the therapy’s safety profile in TROPiCS-02 was similar to prior studies, and no new safety signals were identified in the target patient population. The most frequent serious adverse reactions observed in the study were diarrhea (5%), febrile neutropenia (4%), neutropenia (3%), abdominal pain, colitis, neutropenic colitis, pneumonia, and vomiting (each 2%).
Trodelvy was previously approved for treating certain patients with pre-treated HR+/HER2- metastatic breast cancer and it has an accelerated approval for certain patients with second-line metastatic urothelial cancer.
