New FDA Approved PARP Inhibitor: Talzenna (Talazoparib) & Xtandi |

The FDA recently approved a new PARP inhibitor, Talzenna (talazoparib) to be used alongside Xtandi (enzalutamide) for homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer. The HRR genetic mutations evaluated in the trial that led to FDA approval were ATM, ATR, BRCA1, BRCA2, CDK12, CHEK2, FANCA, MLH1, MRE11A, NBN, PALB2, and RAD51C.
In this video, PCRI's Alex and Medical Oncologist Mark Scholz, MD, explains how Talzenna and Xtandi work, surveys side effects and side effect mitigation, and provide context for how this treatment protocol compares to other similar therapies and the situations in which a patient and his doctor may consider Talzenna + Xtandi as a treatment for his case of prostate cancer.
