Olaparib is a selective and potent inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, PARP1 and PARP2. PARP inhibitors represent a novel class of anti-cancer therapy and they work by taking advantage of a defect in DNA repair in cancer cells with BRCA mutations and inducing cell death.
Olaparib is used to treat a number of BRCA-associated tumours, including ovarian cancer, breast cancer, pancreatic cancer, and prostate cancer. It was first approved by the FDA and EU in December 2014, and by Health Canada in April 2016.
Ovarian cancer
Olaparib is indicated for the maintenance treatment of adults with deleterious or suspected deleterious germline or somatic BRCA-mutated advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to first-line platinum-based chemotherapy.
Olaparib is indicated in combination with bevacizumab for the maintenance treatment of adults with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to first-line platinum-based chemotherapy and whose cancer is associated with homologous recombination deficiency (HRD)-positive status defined by either: a deleterious or suspected deleterious BRCA mutation, and/or genomic instability.
Olaparib is indicated for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer, who are in complete or partial response to platinum-based chemotherapy.
Breast cancer
Olaparib is indicated for the adjuvant treatment of adult patients with deleterious or suspected deleterious gBRCAm human epidermal growth factor receptor 2 (HER2)-negative high risk early breast cancer who have been treated with neoadjuvant or adjuvant chemotherapy.
Olaparib is indicated for the treatment of adult patients with deleterious or suspected deleterious gBRCAm, HER2-negative metastatic breast cancer, who have been treated with chemotherapy in the neoadjuvant, adjuvant, or metastatic setting. Patients with hormone receptor (HR) positive breast cancer should have been treated with a prior endocrine therapy or be considered inappropriate for endocrine therapy.
Pancreatic cancer
Olaparib is indicated for the maintenance treatment of adult patients with deleterious or suspected deleterious gBRCAm metastatic pancreatic adenocarcinoma whose disease has not progressed on at least 16 weeks of a first-line platinum-based chemotherapy regimen.
Prostate cancer
Olaparib is indicated for the treatment of adult patients with deleterious or suspected deleterious germline or somatic homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC) who have progressed following prior treatment with a hormone agent, such as enzalutamide or abiraterone.
It is also indicated in combination with abiraterone and prednisone or prednisolone for the treatment of adult patients with deleterious or suspected deleterious BRCA-mutated (BRCAm) metastatic castration-resistant prostate cancer (mCRPC).
