- Summary
Niraparib is a poly-ADP ribose polymerase inhibitor used to treat recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer responding to platinum based chemotherapy.

- Zejula
- Generic Name
- Niraparib
- DrugBank Accession Number
- DB11793
- Background
Niraparib is an orally active poly (ADP-ribose) polymerase (PARP) inhibitor. By blocking the enzymes responsible for DNA repair, niraparib induces cytotoxicity in cancer cells.6 Niraparib is selective towards PARP-1 and PARP-2.2 First approved by the FDA on March 27, 2017,3 niraparib is used to treat epithelial ovarian, fallopian tube, or primary peritoneal cancer.6 Niraparib was approved by the European Commission on November 16, 2017 7 and by Health Canada on June 27, 2019.8

Niraparib mediated cytotoxic effects in tumour cell lines with or without deficiencies in BRCA1/2. Decreased tumour growth was observed in both mouse xenograft models of human cancer cell lines with deficiencies in BRCA1/2 and human patient-derived xenograft tumour models with homologous recombination deficiency (HRD) that had either mutated or wild-type BRCA1/2.6
In vitro studies suggest that niraparib inhibits dopamine, norepinephrine, and serotonin transporters, which may explain its off-target cardiovascular effects such as increased pulse rate and blood pressure.2
- Mechanism of action
Niraparib is a potent and selective inhibitor of poly(ADP-ribose) polymerase (PARP) enzymes, PARP-1 and PARP-2.7,8 PARPs play an important role in DNA repair. They recognize and repair cellular DNA damage, such as single-strand breaks (SSBs) and double-strand breaks (DSBs). Different DNA repair pathways exist to repair these DNA damages, including the base excision repair (BER) pathway for SSBs and BRCA-dependent homologous recombination for DSBs.4 If BER is impaired, SSBs accumulate and become DSBs, forcing cells to rely on other repair pathways, mainly the homologous recombination (HR) and the nonhomologous end joining, to repair DNA damages.1 However, some cells can have defective or deficient HR resulting from specific mutations in DNA repair genes, such as BRCA1 and 2.2 Inhibiting PARPs in the presence of HR deficiency leads to a phenomenon called 'synthetic lethality,' whereby the PARP inhibitor impedes BER, leading to genetic instability and cell death.1,2
Selectivity towards PARP-1 and PARP-2 is 100-fold higher than for other PARP family members.2 Niraparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes resulting in DNA damage, apoptosis, and cell death.6,7,8
Target Actions Organism APoly [ADP-ribose] polymerase 1 inhibitorHumans APoly [ADP-ribose] polymerase 2 inhibitorHumans - Absorption
Following a single-dose administration of 300 mg niraparib, the mean (±SD) peak plasma concentration (Cmax) was 804 (±403) ng/mL. The exposure (Cmax and AUC) of niraparib increased in a dose-proportional manner with daily doses ranging from 30 mg (0.1 times the approved recommended dose) to 400 mg (1.3 times the approved recommended dose). The accumulation ratio of niraparib exposure following 21 days of repeated daily doses was approximately 2-fold for doses ranging from 30 to 400 mg. The Tmax is about three hours.6
The absolute bioavailability of niraparib is approximately 73%. Food does not appear to affect drug exposure.6
- Volume of distribution
The average (±SD) apparent volume of distribution (Vd/F) was 1,220 (±1,114) L. In a population pharmacokinetic analysis, the Vd/F of niraparib was 1,074 L in patients with cancer.6
- Protein binding
Niraparib is 83% bound to human plasma proteins.6
- Metabolism
Niraparib is primarily metabolized by carboxylesterases (CEs) to form M1, which is a major inactive metabolite. The M1 metabolite can subsequently undergo glucuronidation mediated by UDP-glucuronosyltransferases (UGTs) to form the M10 metabolite.6 In a mass balance study, M1 and M10 were the major circulating metabolites.7 The M1 metabolite can also undergo methylation, monooxygenation, and hydrogenation to form other minor metabolites.5

- Route of elimination
Niraparib is eliminated via multiple pathways, including liver metabolism, hepatobiliary excretion, and renal elimination.8 Following administration of a single oral 300-mg dose of radio-labeled niraparib, the average percent recovery of the administered dose over 21 days was 47.5% (range: 33.4% to 60.2%) in urine and 38.8% (range: 28.3% to 47.0%) in feces. In pooled samples collected over 6 days, unchanged niraparib accounted for 11% and 19% of the administered dose recovered in urine and feces, respectively.6
- Half-life
Following multiple daily doses of 300 mg of niraparib, the mean half-life (t1/2) is 36 hours.6
- Clearance
In a population pharmacokinetic analysis, the apparent total clearance (CL/F) of niraparib was 16.2 L/h in patients with cancer.6
