Niraparib Description:

 

Niraparib (also known as MK-4827) is a potent, orally bioavailable and selective inhibitor of PARP1/2 with IC50 of 3.8 nM and 2.1nM for PARP 1 and 2 respectively. Niraparib is approved by the US FDA on 27 March 2017 for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete or partial response to platinum-based chemotherapy. Niraparib demonstrated high activity in cancer cells with mutant BRCA-1 and BRCA-2 with IC50 in the 10−100 nM range. It is >330-fold selective against PARP3, V-PARP and Tank1. In a whole cell assay, MK-4827 inhibited PARP activity with EC50 of 4 nM. MK-4827 also inhibited proliferation of cancer cells with mutant BRCA-1 and BRCA-2 with CC50 in the 10-100 nM range. MK-4827 strongly enhanced the effect of radiation on a variety of human tumor xenografts, both p53 wild type and p53 mutant.

USP Standard Pharma Grade PARP Inhibitor Niraparib / MK-4827 Raw Powder For CAS 1038915-60-4

 

Medical uses
The drug is approved by the US FDA for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete or partial response to platinum-based chemotherapy.

In a study with 553 patients, progression-free survival (PFS) for patients with a deleterious or suspected deleterious BRCA mutation in the germline was 21.0 months under niraparib therapy, as compared to 5.5 months under placebo. Patients without such a mutation had a PFS of 9.3 months under niraparib versus 3.9 months under placebo.

 

 

Side effects
The most common side effects in studies were low blood cell counts, namely thrombocytopenia (in 61% of patients, severe in 29%), anemia (in 50%, severe in 25%) and neutropenia (in 30%, severe in 20%). Other, mostly mild to moderate side effects included nausea, fatigue, and constipation. In a study running over 250 days (median), 15% of patients had to permanently discontinue niraparib due to adverse effects.
