Matulonis, MD, director, Gynecologic Oncology, Dana-Farber Cancer Institute, professor of Medicine, Harvard Medical School, discusses results from the phase II open-label, single-arm QUADRA study evaluating niraparib in patients with relapsed ovarian cancer who have received ≥3 prior chemotherapy regimens during the 2018 ASCO Annual Meeting.

During the 2018 ASCO Annual Meeting, Ursula A. Matulonis, MD, director, Gynecologic Oncology, Dana-Farber Cancer Institute, professor of Medicine, Harvard Medical School, discusses results from the phase II open-label, single-arm QUADRA study evaluating niraparib (Zejula) in patients with relapsed ovarian cancer who have received ≥3 prior chemotherapy regimens.

There was a 29% response rate found with niraparib, which is a very exciting result in this heavily pretreated population, Matulonis says. In patients with heavily pretreated ovarian cancer with a germlineBRCAmutation, the response rate was over 40%, while patients with platinum-resistant ovarian cancer had a response rate of approximately 25%.
