Официальное название

A Phase III Randomized Controlled Clinical Study Comparing BL-M07D1 With Physician's Choice of Chemotherapy in Patients With HER2-Expressing Platinum-Resistant Recurrent Epithelial Ovarian Cancer, Fallopian Tube Cancer, and Primary Peritoneal Cancer

Обзор

This trial is a registrational Phase III, randomized, open-label, multicenter study to evaluate the efficacy and safety of BL-M07D1 in patients with HER2-expressing platinum-resistant recurrent epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer.
