Niraparib (MK-4827) displays excellent PARP 1 and 2 inhibition. Inhibition of PARP in the context of defects in other DNA repair mechanisms provide a tumor specific way to kill cancer cells. Niraparib is in development with TESARO, under licence from Merck & Co, for the treatment of cancers (ovarian, fallopian tube and peritoneal cancer, breast cancer, prostate cancer and Ewing's sarcoma). Niraparib was characterized in a number of preclinical models before moving to phase I clinical trials, where it showed excellent human pharmacokinetics suitable for once a day oral dosing, achieved its pharmacodynamic target for PARP inhibition, and had promising activity in cancer patients. It is currently being tested in phase 3 clinical trials as maintenance therapy in ovarian cancer and as a treatment for breast cancer.

Sample Use Guides

In Vivo Use Guide

Niraparib (PO, 110-210 mg) successfully inhibited poly(ADP-ribose) polymerase (PARP) during a phase I trial in patients with BRCA-deficient or sporadic cancers associated with homologous recombination repair defects. Niraparib (PO, 30-210 mg) was well tolerated during a phase I trial in patients with BRCA-deficient or sporadic cancers associated with homologous recombination repair defects. Maximum tolerated dose (MTD) of niraparib in patients with advanced solid tumours was 300 mg.

Route of Administration: Oral

In Vitro Use Guide

Niraparib (MK-4827) inhibited proliferation of cancer cells with mutant BRCA-1 and BRCA-2 with CC(50) in the 10-100 nM range.
