Lynparza and Imfinzi combination improved progression-free survival in newly diagnosed patients with advanced ovarian cancer without tumour BRCA mutations in DUO-O Phase III trial
Positive high-level results from a planned interim analysis of the DUO-O Phase III trial showed treatment with a combination of Lynparza (olaparib), Imfinzi (durvalumab), chemotherapy and bevacizumab demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) versus chemotherapy plus bevacizumab (control arm) in newly diagnosed patients with advanced high-grade epithelial ovarian cancer without tumour BRCA mutations. Patients were treated with Imfinzi in combination with chemotherapy and bevacizumab followed by Imfinzi, Lynparza and bevacizumabas maintenance therapy.
In an additional arm, Imfinzi, chemotherapy plus bevacizumab showed a numerical improvement in PFS versus the control arm but did not reach statistical significance at this interim analysis.
At the time of this planned interim analysis, the overall survival (OS) and other secondary endpoints are immature and will be formally assessed at a subsequent analysis.
Ovarian cancer is one of the most common gynaecologic cancers.1 Over two thirds of patients are diagnosed with advanced disease which can progress quickly, often within two years, diminishing their quality of life despite treatment. Unfortunately, 50-70% of patients with advanced disease die within five years.2-5
Philipp Harter, Director, Department of Gynaecology and Gynaecologic Oncology, Evangelische Kliniken Essen-Mitte, Germany and principal investigator for the trial, said: “DUO-O showcases the power of academia and industry collaboration in advancing new treatment combinations for patients with ovarian cancer. I’m grateful for the academic cooperative study groups and patients around the world that made this trial possible and look forward to sharing the results with the clinical community.”
Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “While there has been significant progress for patients with advanced ovarian cancer, an unmet need still remains. These data from the DUO-O trial provide encouraging evidence for this Lynparza and Imfinzi combination in patients without tumour BRCA mutations and reinforce our continued commitment to finding new treatment approaches for these patients. It will be important to understand the key secondary endpoints as well as data for relevant subgroups.
AstraZeneca in oncology
AstraZeneca is leading a revolution in oncology with the ambition to provide cures for cancer in every form, following the science to understand cancer and all its complexities to discover, develop and deliver life-changing medicines to patients.
The Company’s focus is on some of the most challenging cancers. It is through persistent innovation that AstraZeneca has built one of the most diverse portfolios and pipelines in the industry, with the potential to catalyse changes in the practice of medicine and transform the patient experience.
By harnessing the power of six scientific platforms – Immuno-Oncology, Tumour Drivers and Resistance, DNA Damage Response, Antibody Drug Conjugates, Epigenetics and Cell Therapies – and by championing the development of personalised combinations, AstraZeneca has the vision to redefine cancer treatment and, one day, eliminate cancer as a cause of death.
AstraZeneca (LSE/STO/Nasdaq: AZN) is a global, science-led biopharmaceutical company that focuses on the discovery, development and commercialisation of prescription medicines, primarily for the treatment of diseases in three therapy areas – Oncology, Cardiovascular, Renal & Metabolism and Respiratory & Immunology.
