–  Submission based on data from the Phase III PRIMA clinical study that demonstrated clinically meaningful outcomes of niraparib maintenance treatment in the first-line setting regardless of biomarker status

LONDON, UK I February 27, 2020 I GlaxoSmithKline plc announced that the European Medicines Agency (EMA) has validated the company’s Type II Variation (T2V) for Zejula (niraparib) as a maintenance treatment in the first-line setting for women with advanced ovarian cancer who responded to platinum-based chemotherapy regardless of biomarker status. Validation of the T2V confirms that the submission is accepted and begins the formal review process by the EMA’s Committee for Human Medicinal Products (CHMP).

The submission is based on data from the PRIMA study (ENGOT-OV26/GOG-3012), which demonstrated clinically meaningful outcomes of niraparib treatment in the first-line maintenance setting.i Results from the PRIMA study were presented at the 2019 European Society for Medical Oncology Congress and simultaneously published in the New England Journal of Medicine. The PRIMA study enrolled women who responded to first-line treatment with platinum-based chemotherapy, including those with high risk of disease progression, a population with high unmet need and previously under-represented in first-line ovarian cancer studies.

In Europe, ovarian cancer is the sixth deadliest cancer among women and more than 65,000 women are diagnosed each year.ii Most women are diagnosed with advanced (stage III or IV) ovarian cancer and have a five-year survival rate of ~30%.iii Despite high response rates to platinum-based chemotherapy in the first-line, approximately 85% of women with advanced ovarian cancer will see their disease return.iv With each recurrence, the time a woman may spend without her cancer progressing until the next recurrence gets shorter.

About PRIMA
PRIMA is a double-blind, randomised Phase III study designed to evaluate niraparib versus placebo in women being treated first-line for stage III or IV ovarian cancer. The study assessed the efficacy of niraparib as maintenance therapy, as measured by progression free survival. Patients in complete or partial response to first-line platinum-based chemotherapy were randomised 2:1 to niraparib or placebo.

About Zejula (niraparib)
Niraparib is an oral, once-daily PARP inhibitor that is currently being evaluated in multiple pivotal trials. GSK is building a robust niraparib clinical development programme by assessing activity across multiple tumour types and by evaluating several potential combinations of niraparib with other therapeutics. The ongoing development programme for niraparib includes several combination studies, including a Phase III study as a first-line triplet maintenance treatment in ovarian cancer (FIRST).

Important Information for ZEJULA

Zejula approved indication:
Zejula is indicated as monotherapy for the maintenance treatment of adult patients with platinum‑sensitive relapsed high grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in response (complete or partial) to platinum‑based chemotherapy.
