NameTalazoparib
Groups
  • investigational
  • approved
DescriptionTalazoparib is an inhibitor of mammalian polyadenosine 5’-diphosphoribose polymerases (PARPs), enzymes responsible for regulating essential cellular functions, such as DNA transcription and DNA repair.[L47236] Developed by Pfizer, talazoparib was first approved by the FDA in October 2018 [A260346] and by the EMA in June 2019.[L47296] It was approved by Health Canada in September 2020.[L47301] Talazoparib is currently used in the treatment of BRCA-mutated breast cancer and HRR-mutated prostate cancer.[L47236, L47301, L47306]
Synonyms
  • Talazoparib tosylate
  • Talazoparib
Brand NamesTalzenna
IndicationTalazoparib is indicated for the treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) HER2-negative locally advanced or metastatic breast cancer. This indication is approved by the FDA, EMA, and Health Canada.[L47236, L47301, L47306] In the US, talazoparib is also indicated in combination with [enzalutamide] for the treatment of adult patients with HRR gene-mutated metastatic castration-resistant prostate cancer (mCRPC).[L47236]
