Pamiparib for germline BRCA mutation-associated recurrent advanced ovarian, fallopian tube or primary peritoneal cancer

Epithelial ovarian cancers are gynecological malignancies with the poorest prognosis. Intensive research over the past few years has demonstrated ovarian cancer is a type of cancer in which new molecularly targeted drugs significantly affect patients' fate and prognosis. These drugs are poly [ADP-ribose] polymerase (PARP) inhibitors, which are used for maintenance treatment. These molecules continue to be intensively studied--their combination with other targeted therapies is carefully evaluated as more of them are discovered. Four PARP inhibitors have been approved by the U.S. Food and Drug Administration (FDA) so far. Olaparib, rucaparib and niraparib are approved for various indications in epithelial ovarian cancer, fallopian tube or primary peritoneal cancer, while the PARP inhibitors for the treatment of breast cancer are olaparib and talazoparib. Olaparib is also approved for the treatment of pancreatic cancer as well as prostate cancer, and rucaparib is also approved for prostate cancer. Pamiparib (Partruvix) is a new, selective inhibitor of PARP-1 and PARP-2 which was discovered by BeiGene Ltd. On April 30, 2021, pamiparib obtained its first registration worldwide--it was approved in China for the treatment of women with recurrent ovarian, fallopian tube or primary peritoneal cancer with confirmed germline BRCA mutation.
