ZEJULA (niraparib tosylate)

Orphan Drug Breakthrough Therapy Priority Review Fast Track
Oncology Approved 2017-03-27

Zejula (niraparib tosylate) is a PARP inhibitor indicated for the maintenance treatment of adult patients with advanced or recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer. It is utilized for patients who have achieved a complete or partial response to platinum-based chemotherapy. For first-line maintenance, the drug is indicated for patients with homologous recombination deficiency (HRD)-positive status, while for recurrent cases, it is indicated for patients with germline BRCA mutations. Treatment selection requires the use of an FDA-approved companion diagnostic to identify appropriate biomarkers.

How ZEJULA Works

Niraparib inhibits PARP-1 and PARP-2 enzymes, which play a critical role in the repair of DNA. The drug's activity involves the inhibition of enzymatic activity and the increased formation of PARP-DNA complexes, resulting in DNA damage and cell death. This cytotoxicity is particularly effective in tumor cells with homologous recombination deficiency or BRCA mutations, where DNA repair pathways are already compromised.
