ORM-15341, also known as BAY-1896953, is a nonsteroidal antiandrogen (NSAA) and the major active metabolite of darolutamide (ODM-201, BAY-1841788), an NSAA which is under development as a hormonal antineoplastic agent for the treatment of metastatic prostate cancer.[2][3][4][5] Similarly to its parent compound, ORM-15341 acts as a highly selective, high-affinity, competitive silent antagonist of the androgen receptor (AR).[2][3][4][5] Both agents show much higher affinity and more potent inhibition of the AR relative to the other NSAAs enzalutamide and apalutamide, although they also possess much shorter and comparatively less favorable terminal half-lives.[2][3][4][5] They have also been found not to activate certain mutant AR variants that enzalutamide and apalutamide do activate.[2][3][4][5] Both darolutamide and ORM-15341 show limited central nervous system distribution, indicating peripheral selectivity, and little or no inhibition or induction of cytochrome P450 enzymes such as CYP3A4, unlike enzalutamide and apalutamide.[2][3][4][5]
