Carboplatin-Enhanced Therapy in BRCA-Mutated or Neuroendocrine-Differentiated Aggressive Metastatic Castration-Sensitive Prostate Cancer

The current standard of patients with de novo metastatic hormone sensitive prostate cancer (mHSPC) is to offer androgen deprivation therapy (ADT) with androgen receptor pathway inhibitors (ARPI). In addition, upfront 6 cycles of docetaxel, if patient is eligible, and prostate radiotherapy for those with low-volume disease are recommended. BRCA mutations (BRCAm) and neuroendocrine differentiation (NED) confer a poor prognosis in mHSPC and the current standard of care for these patients remains suboptimal. While PARP inhibitors have shown efficacy in BRCAm castration-resistant prostate cancer, concerns exist about their toxicity and resistance when used earlier in the mHSPC setting. Carboplatin has demonstrated activity in BRCAm and neuroendocrine tumors but has not been extensively studied in mHSPC. The combination of carboplatin and docetaxel is expected to enhance treatment efficacy and delay progression.
