N-Desmethylapalutamide is a nonsteroidal antiandrogen (NSAA) and the major active metabolite of apalutamide, an NSAA which is used as a hormonal antineoplastic agent in the treatment of metastatic prostate cancer.[1] It has similar activity to that of apalutamide and, with apalutamide therapy, circulates at similar concentrations to those of apalutamide at steady state.[1] N-Desmethylapalutamide is formed from apalutamide in the liver by the cytochrome P450 enzymes CYP2C8 and CYP3A4.[1]
