Professor Philipp Harter, Director, Department of Gynaecology and Gynaecologic Oncology, Evangelische Kliniken Essen-Mitte, Germany, and principal investigator for the trial, said: “The primary aim of first-line treatment of patients with advanced ovarian cancer is long-term control over the disease, but still too many patients progress quickly and face poor clinical outcomes today. Data from the DUO-O trial interim progression-free survival analysis provide evidence for further improvement with olaparib and durvalumab combination versus chemotherapy and bevacizumab alone in patients without tumour BRCA mutations.”
