Niraparib is an oral, once-daily inhibitor of poly ADP ribose polymerase (PARP). The drug is being developed for the treatment of various cancer types.

PRIMA is a randomised, double-blind, placebo-controlled trial that compared the efficacy of niraparib to placebo.

The trial involved a personalised starting dose of once-a-day 200mg niraparib in participants with a baseline weight of less than 77kg or platelet count of less than 150K/μL and 300mg in all other subjects.

The Phase III study met its primary endpoint demonstrating a statistically significant improvement in progression-free survival, irrespective of the biomarker status.

In addition, the safety and tolerability profile of the drug was observed to be consistent with that of prior studies.

GSK chief scientific officer and R&D president Dr Hal Barron said: “Almost 300,000 women around the world are diagnosed with ovarian cancer every year, yet only about 15% of patients are currently eligible to receive PARP inhibitors as their initial therapy. These exciting data demonstrate that Zejula has the potential to significantly benefit even more women with this devastating cancer.”

Apart from the PRIMA study, niraparib is being studied in the Phase III BRAVO trial for germline BRCA-mutated, metastatic breast cancer and Phase II QUADRA study in ovarian cancer patients.

The drug is also undergoing studies as a combination therapy for metastatic, triple-negative breast cancer and platinum-sensitive ovarian cancer.

Janssen Biotech licensed global rights, excluding Japan, to develop and commercialise the drug for prostate cancer.
