Detailed Summary

This is a prospective, randomized, open-label phase II study comparing cognitive outcomes between men with metastatic and non-metastatic castration resistant prostate cancer (CRPC) or metastatic hormone sensitive prostate cancer (HSPC). Approximately 132 patients will be enrolled. Eligible patients will be randomized in a 1:1 fashion to treatment with enzalutamide 160 mg orally daily or darolutamide 600 mg orally twice daily, in combination with standard LHRH agonist based treatment. Cognitive assessments will be performed using modules from Cambridge Neuropsychological Test Automated Battery (CANTAB) an internationally recognized software for assessing cognitive function and impairment.
