An evaluation of talazoparib plus enzalutamide for the treatment of metastatic castration-resistant prostate cancer

Emerging biomarkers like TMPRSS2-ERG and RB1 gene mutations have been recently reported as potential predictors of clinical outcome in the TALAPRO-2 all-comers population. Genomic markers for homologous recombination deficiency (HRD) are other potential drivers of response to PARPi/ARPI combination. Further investigation is needed to refine treatment strategies, including targeting non-HRR mutations, and to expand the role of this combination therapy in earlier stages of prostate cancer.
