BERLIN, July 08, 2016 (GLOBE NEWSWIRE) -- ENGOT (European Network of Gynaecological Oncology Trial Groups), today announced that the Phase 3 ENGOT-OV16/NOVA trial of niraparib successfully achieved its primary endpoint of progression-free survival (PFS). This trial is led by NSGO (Nordic Society of Gynaecological Oncology) in partnership with TESARO, Inc. and is the first successful Phase 3 trial of a PARP inhibitor to be completed in ovarian cancer. More than 500 patients with recurrent disease who were in response to their most recent platinum-based chemotherapy regimen enrolled in the trial.
As previously reported, this trial demonstrated that niraparib significantly prolonged PFS compared to control among patients who are germline BRCA mutation (gBRCAmut) carriers, among patients who are not germline BRCA mutation (non-gBRCAmut) carriers but who have homologous recombination deficient (HRD) tumors as determined by the Myriad myChoice®HRD test, and overall in patients who are not germline BRCA mutation carriers.
“The data suggest that niraparib, if approved, will be a step forward in the management of our patients and a potential new treatment option for ovarian cancer patients,” said Mansoor Raza Mirza, M.D., Study Chair and Medical Director of NSGO.
“ENGOT with their collaborative clinical trial groups has put a lot of effort to bring this trial to success and this is a great example how today international collaboration between academic groups and industry can benefit patients,” said Christian Marth, President of ENGOT.
“We are extremely grateful to the patients, caregivers, and investigators, including our partners at ENGOT, who participated in this trial. The results of this study demonstrate that a single, daily, oral dose of niraparib is superior to control in prolonging PFS in women with recurrent ovarian cancer,” said Mary Lynne Hedley, Ph.D., President and COO of TESARO. “In keeping with our mission of responsible drug development, ENGOT-OV16/NOVA was designed to define those patients most likely to benefit from niraparib treatment and, in so doing, optimize the benefit/risk profile for patients. We believe we have achieved that goal and look forward to our presentation of the full data set from this study at the European Society for Medical Oncology (ESMO) congress in October.”
About the Phase 3 ENGOT-OV16/NOVA Clinical Trial
NOVA is a double-blind, placebo-controlled, international Phase 3 trial of niraparib that planned to enroll 490 patients with recurrent ovarian cancer who were in a response to their most recent platinum-based chemotherapy. Patients were enrolled into one of two independent cohorts based on germline BRCA mutation status. One cohort enrolled patients who were germline BRCA mutation carriers (gBRCAmut), and the second cohort enrolled patients who were not germline BRCA mutation carriers (non-gBRCAmut). The non-gBRCAmut cohort included patients with HRD-positive tumors, including those with somatic BRCA mutations and other HR defects, and patients with HRD-negative tumors. Within each cohort, patients were randomized 2:1 to receive niraparib or placebo and were treated continuously with placebo or 300 milligrams of niraparib, dosed as three 100 milligram tablets once per day, until progression. The primary endpoint of this study was progression-free survival (PFS). Secondary endpoints include patient-reported outcomes, chemotherapy-free interval length, PFS2, overall survival, and other measures of safety and tolerability.
The most common (≥10%) treatment-emergent grade 3/4 adverse events among all patients treated with niraparib were thrombocytopenia (28.3%), anemia (24.8%) and neutropenia (11.2%). Adverse events were generally managed via dose modifications. The discontinuation rate was 14.7% for niraparib treated patients and 2.2% for control.
More information about this trial is available at clinicaltrials.gov/show/NCT01847274.
Niraparib is an investigational agent and, as such, has not been approved by the U.S. FDA or any other regulatory agencies.
About Niraparib
Niraparib is an oral, once-daily PARP inhibitor that is currently being evaluated in three ongoing pivotal trials. TESARO is building a robust niraparib franchise by assessing activity across multiple tumor types and by evaluating several potential combinations of niraparib with other therapeutics. The ongoing development program for niraparib includes the Phase 3 trial in patients with ovarian cancer (the NOVA trial) as described above; a registrational Phase 2 treatment trial in patients with ovarian cancer (the QUADRA trial); a Phase 3 trial for the treatment of patients with BRCA-positive breast cancer (the BRAVO trial); and a Phase 3 trial in patients with first-line ovarian cancer (the PRIMA trial). Several collaborator-sponsored studies are also underway, including combination trials of niraparib plus pembrolizumab and bevacizumab. Janssen Biotech has licensed rights to develop and commercialize niraparib specifically for patients with prostate cancer worldwide, except in Japan
