What's Happening?
Daiichi Sankyo and Merck have commenced the HERTHENA-Breast04 phase 3 trial, evaluating patritumab deruxtecan in patients with metastatic hormone receptor-positive, HER2-negative breast cancer. The trial aims to assess the drug's efficacy and safety compared to standard treatments. Patritumab deruxtecan, a HER3-directed antibody drug conjugate, has shown promise in earlier studies. The trial will enroll approximately 1,000 patients globally, focusing on those who have progressed following endocrine and CDK4/6 inhibitor therapy.
