ESMO Hot Topic Express | Updated Results on Patient Outcomes, Drug Exposure, Safety, and Quality of Life Relevance in the TALAPRO-2 Study
In recent years, there have been groundbreaking advancements in the exploration of treatment modalities for prostate cancer, particularly in the use of PARP inhibitors in combination with novel hormonal therapies, offering new hope for the treatment of metastatic castration-resistant prostate cancer (mCRPC). The TALAPRO-2 study has demonstrated that the combination of talazoparib with enzalutamide significantly improves radiographic progression-free survival (rPFS) in the overall mCRPC patient population (HR=0.63; 95% CI, 0.51–0.78; P<0.0001) and in mCRPC patients with homologous recombination repair (HRR) gene defects (HR=0.45; 95% CI, 0.33–0.61; P<0.0001) compared to placebo in combination with enzalutamide[1]. As a result, the combination therapy of talazoparib and enzalutamide received FDA approval on June 20th of this year for first-line use in mCRPC patients with HRR gene mutations.
