An oral targeted therapy used to treat advanced ovarian, fallopian tube, and peritoneal cancers.
AKEEGA with prednisone is indicated for the treatment of adult patients with deleterious or suspected deleterious BRCA2 -mutated ( BRCA2 m) metastatic castration-sensitive prostate cancer (mCSPC). AKEEGA with prednisone is indicated for the treatment of adult patients with deleterious or suspected deleterious BRCA -mutated ( BRCA m) metastatic castration-resistant prostate cancer (mCRPC). Select patients for therapy based on an FDA-approved test for AKEEGA [see Dosage and Administration (2.1) ] . AKEEGA is a combination of niraparib, a poly (ADP-ribose) polymerase (PARP) inhibitor, and abiraterone acetate, a CYP17 inhibitor indicated with prednisone for the treatment of adult patients with: deleterious or suspected deleterious BRCA2 -mutated ( BRCA2 m) metastatic castration-sensitive prostate cancer (mCSPC). deleterious or suspected deleterious BRCA -mutated ( BRCA m) metastatic castrat…
12.1 Mechanism of Action Niraparib is an inhibitor of PARP enzymes, including PARP-1 and PARP-2, that play a role in DNA repair. In vitro studies have shown that 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. Increased niraparib‑induced cytotoxicity was observed in tumor cell lines with or without deficiencies in BRCA1/2 . Niraparib decreased tumor growth in mouse xenograft models of human cancer cell lines with deficiencies in BRCA1/2 and in human patient‑derived xenograft tumor models with homologous recombination deficiency (HRD) that had either mutated or w…
