Roche’s Giredestrant Promising Data in Early Breast Cancer
Roche says its investigational selective estrogen receptor degrader (SERD) giredestrant significantly improved invasive disease-free survival in people with early-stage, ER-positive/HER2-negative breast cancer, marking the first time an oral SERD has shown superiority to standard endocrine therapy in the adjuvant setting.
The Phase 3 lidERA trial reached its primary endpoint at a planned interim analysis, demonstrating giredestrant’s statistically significant and clinically meaningful benefit over standard endocrine monotherapy, according to the company. Overall survival data remain immature, though Roche reported a positive trend, and safety data were consistent with prior studies and showed no unexpected signals, it adds.
Roche says giredestrant is being studied across five company-sponsored Phase 3 trials spanning early-stage, endocrine-sensitive, and resistant advanced disease, including combinations with CDK4/6 inhibitors, everolimus, and Phesgo (pertuzumab, trastuzumab, and hyaluronidase).
