Exposure‐Response Assessment of Enzalutamide and Its Major Metabolites in a Real‐World Cohort of Patients with Metastatic Castration‐Resistant Prostate Cancer

Abstract

Enzalutamide is an oral agent for the treatment of metastatic castration‐resistant prostate cancer (mCRPC); N‐desmethyl enzalutamide is its active metabolite, which has clinically relevant anti‐androgen capacities similar to enzalutamide, and carboxylic acid enzalutamide is an inactive metabolite. The aim of our study was to investigate the relationship between enzalutamide and N‐desmethyl enzalutamide exposure and treatment response in a real‐world cohort of patients with mCRPC.
