Two PARP Inhibitors OK’d for New Prostate Cancer Indication
Although poly ADP-ribose polymerase (PARP) inhibitors are not new to the market, two of them recently gained approval for use in prostate cancer for the first time. The therapies will bring a new option for the treatment of certain subpopulations of patients.
On May 19, the FDA expanded the label of AstraZeneca and Merck & Co., Inc.’s Lynparza (olaparib) to include the treatment of people with deleterious or suspected deleterious germline or somatic homologous recombination repair gene-mutated metastatic castration-resistant prostate cancer who have progressed following treatment with Xtandi (enzalutamide) or Zytiga/Yonsa (abiraterone acetate). Lynparza also has approvals in breast, ovarian and pancreatic cancers.
