Enzalutamide | Xtandi | MDV3100|ASP9785 | Hormone - Anti-androgens 55 | Xtandi (enzalutamide) is a second-generation small molecule inhibitor of androgen receptor, thereby resulting in decreased tumor growth (PMID: 24009414, PMID: 25945058). Xtandi (enzalutamide) is FDA-approved for use in patients with castration-resistant prostate cancer, metastatic hormone-sensitive prostate cancer, and non-metastatic castration-sensitive prostate cancer with biochemical recurrence at high risk for metastasis (FDA.gov). |
Talazoparib | Talzenna | BMN673 | PARP Inhibitor (Pan) 31 | Talzenna (talazoparib) is an inhibitor of PARP1 and PARP2, which prevents the DNA repair of single strand DNA breaks, thus causing the accumulation of DNA strand breaks, genomic instability and apoptosis, and leads to lethality in homologous recombination repair deficient cells (PMID: 28242752). Talzenna (talazoparib) is FDA approved for use in patients with ERBB2 (HER2)-negative breast cancer harboring deleterious or suspected deleterious germline BRCA mutations, and in combination with Xtandi (enzalutamide) in patients with homologous recombination repair gene (ATM, ATR, BRCA1/2, CDK12, CHEK2, FANCA, MLH1, MRE11A, NBN, PALB2, or RAD51C)-mutated metastatic castration-resistant prostate cancer (FDA.gov). |
