Neeraj Agarwal, MD, of the Huntsman Cancer Institute, University of Utah, discusses phase III results from the TALAPRO-2 study, which suggested an improvement in radiographic progression-free survival with the combination of talazoparib and enzalutamide over standard-of-care enzalutamide alone as first-line treatment in patients with metastatic castration-resistant prostate cancer. The improvement was seen regardless of homologous recombination repair gene mutations. The combination regimen delayed the time to chemotherapy and worsening in global health status and quality of life. (Abstract LBA17).
