Overview

Generic Name(s):
niraparib
Trade Name(s):
Zejula
NCI Definition [1]:
An orally bioavailable inhibitor of poly (ADP-ribose) polymerase (PARP) types 1 and 2 (PARP-1 and -2), with antineoplastic activity. Upon administration, niraparib binds to and inhibits the activity of PARP-1 and -2, thereby inhibiting PARP-1 and -2-mediated DNA repair, enhancing the accumulation of DNA strand breaks, promoting genomic instability and resulting in apoptosis. The PARP family of proteins catalyzes post-translational ADP-ribosylation of nuclear proteins and is activated by single-strand DNA (ssDNA) breaks.

Biomarker-Directed Therapies

Niraparib has been investigated in 72 clinical trials, of which 66 are open and 6 are closed. Of the trials investigating niraparib, 23 are phase 1 (19 open), 11 are phase 1/phase 2 (10 open), 31 are phase 2 (30 open), and 7 are phase 3 (7 open).

BRCA1 Loss, BRCA1 Mutation, and BRCA2 Loss are the most frequent biomarker inclusion criteria for niraparib clinical trials.

Breast carcinoma, malignant solid tumor, and fallopian tube carcinoma are the most common diseases being investigated in niraparib clinical trials [2].
