An oral targeted therapy used to treat advanced ovarian and prostate cancers.
RUBRACA is a poly (ADP-ribose) polymerase (PARP) inhibitor indicated: Ovarian cancer for the maintenance treatment of adult patients with a deleterious BRCA mutation (germline and/or somatic)-associated recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy. ( 1.1 ) Prostate cancer for the treatment of adult patients with a deleterious BRCA mutation (germline and/or somatic)-associated metastatic castration-resistant prostate cancer (mCRPC) who have been treated with androgen receptor-directed therapy. Select patients for therapy based on an FDA-approved companion diagnostic for RUBRACA. ( 1.2 , 2.1 ) 1.1 Maintenance Treatment of BRCA -mutated Recurrent Ovarian Cancer RUBRACA is indicated for the maintenance treatment of adult patients with a deleterious BRCA mutation (germline and/or somatic)-a…
12.1 Mechanism of Action Rucaparib is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP-1, PARP-2, and PARP-3, which play a role in DNA repair. In vitro studies have shown that rucaparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes resulting in DNA damage, apoptosis, and cancer cell death. Increased rucaparib-induced cytotoxicity and anti-tumor activity was observed in tumor cell lines with deficiencies in BRCA1/2 and other DNA repair genes. Rucaparib has been shown to decrease tumor growth in mouse xenograft models of human cancer with or without deficiencies in BRCA .
