3 Mateo J, Carreira S, Sandhu S, et al. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. The results also showed olaparib could extend survival by over three months, on average. Richard R. Kerr. They cover the use of the drugs in men whose prostate cancer has spread, or metastasized, and whose disease has stopped responding to standard hormone treatments, often called castration-resistant disease. FDA approves 2 PARP inhibitors for certain men with prostate cancer. Olaparib is a PARP inhibitor that improves clinical outcomes in BRCA1/2-mutated metastatic breast cancer, as well as ovarian, prostate, and pancreatic cancers [1-4]. It works by stimulating the immune system to fight cancer.

Olaparib and Radium Ra 223 Dichloride in Treating Men With Metastatic Castration-Resistant Prostate Cancer That Has Spread to the Bone. Trial of PARP inhibitors in Prostate Cancer (TOPARP-A) showed olaparib, a PARP inhibitor, to be most effective in mCRPC harboring impaired DNA repair mechanisms after progressing on one or two regimens of chemotherapy ( N Engl J Med 2015;373:1697-1708). OLAPARIB and RUCAPARIB (PARP inhibitors): These newly FDA approved agents now offer a much needed additional treatment option for men with metastatic castration resistant prostate cancer (mCRPC). Olaparib is a selective inhibitor of enzymes of the poly (ADP-ribose) polymerase family (e.g., PARP-1, PARP-2, and PARP-3). Olaparib works by interfering with a ⦠Dna-Repair defects and olaparib in metastatic prostate cancer. This phase II trial studies how well durvalumab and olaparib work in treating prostate cancer in men predicted to have specific genetic mutations (a high neoantigen load). Conclusions: In men with metastatic castration-resistant prostate cancer who had disease progression while receiving enzalutamide or abiraterone and who had alterations in genes with a role in homologous recombination repair, olaparib was associated with longer progression-free survival and better measures of response and patient-reported end points than either enzalutamide or abiraterone. Olaparib is a drug that counteracts the effects of a BRCA gene mutation, and was licensed for use in ovarian cancer in December last year. ... Olaparib ⦠More serious adverse events were observed in patients who received olaparib and abiraterone than abiraterone alone. The somatic and germline mutational landscape of mCRPC shows that ~15-25% have HRD gene alterations. 1.

In 2019, results from the PROfound trial showed olaparib delayed the progression of metastatic prostate cancer in men whose cancer cells have faulty DNA repair genes by around four months, compared to standard treatments like enzalutamide and abiraterone. Dna-Repair defects and olaparib in metastatic prostate cancer. Venous Thromboembolic Events: Including pulmonary embolism, occurred in 7% of patients with metastatic castration-resistant prostate cancer who received LYNPARZA plus androgen deprivation therapy (ADT) compared to 3.1% of patients receiving enzalutamide or abiraterone plus ADT in the PROfound study. Participants are randomized (1:1) and receive either carboplatin (AUC 5, IV) every 21 days, first or olaparib taken orally (300 mg), twice daily in 28 day cycles, until intolerance, complete response, or progression by Prostate Cancer Working Group 3 (PCWG3) criteria. The FDA approved olaparib for treatment of certain men with metastatic castration-resistant prostate cancer. Lynparza is indicated as monotherapy for the treatment of adult patients with metastatic castration-resistant prostate cancer (mCRPC) and BRCA1/2 mutations (germline and/or somatic) who have progressed following prior therapy that included a new hormonal agent. Any prior treatment for castration-resistant prostate cancer (CRPC) with carboplatin, cisplatin, cabazitaxel or olaparib. The results, published last week, showed Olaparib to be effective in men with advanced prostate cancer who had one of 15 genetic mutations in their prostate cancer. Olaparib has antitumour activity against metastatic castration-resistant prostate cancer with DDR gene aberrations, supporting the implementation of genomic stratification of metastatic castration-resistant prostate cancer in clinical practice.
