MedKoo CAT#: 200422
Description: Olaparib, also known as AZD-2281 or KU-59436 , is a small molecule inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) with potential chemosensitizing, radiosensitizing, and antineoplastic activities. Olaparib selectively binds to and inhibits PARP, inhibiting PARP-mediated repair of single strand DNA breaks; PARP inhibition may enhance the cytotoxicity of DNA-damaging agents and may reverse tumor cell chemoresistance and radioresistance. PARP catalyzes post-translational ADP-ribosylation of nuclear proteins and can be activated by single-stranded DNA breaks. Olaparib was approved in 2014 for treating advanced ovarian cancer.

Olaparib (AZD-2281, trade name Lynparza) is an FDA-approved chemotherapeutic agent, developed by KuDOS Pharmaceuticals and later by AstraZeneca. It is an inhibitor of poly ADP ribose polymerase (PARP), an enzyme involved in DNA repair. It acts against cancers in people with hereditary BRCA1 or BRCA2 mutations, which includes many ovarian, breast, and prostate cancers. Early Phase I trials were promising, and olaparib underwent Phase II trials. However, in December 2011, AstraZeneca announced following interim analysis of a phase-II study which indicated that the previously reported progression free survival benefit was unlikely to translate into an overall survival benefit, that it would not progress into Phase III development for the maintenance treatment of serous ovarian cancer, and took a charge of $285 million. The decision to discontinue development of the drug was reversed in 2013, with AstraZeneca posting a new Phase III trial of Olaparib for patients with BRCA mutated ovarian cancer in April 2013. On December 19, 2014, the FDA approved olaparib as monotherapy (at 400 mg taken twice per day) for patients with germline BRCA mutated (gBRCAm) advanced ovarian cancer who have been treated with three or more prior lines of chemotherapy.
