A new drug application (NDA) to the FDA has been completed for niraparib as a maintenance treatment for women with recurrent platinum-sensitive ovarian, fallopian tube, or primary peritoneal cancer, according to the company developing the PARP1/2 inhibitor, Tesaro.
Patient demographics were well balanced between the arms for each cohort. In the germline BRCA
group, the median age was 57 years and 65.9% had an ECOG performance status (PS) of 0. In the placebo group, the median age was 58 years and 73.8% of patients had an ECOG PS of 0. Overall, 48.6% and 53.8% of patients had received ≥3 prior therapies, in the niraparib and placebo arms, respectively.
Across both cohorts, the majority of patients had stage III cancer (68.8% to 74.1%). Approximately half of patients had achieved a complete response to prior platinum-based therapy and a quarter had received prior bevacizumab. In the non-BRCA
