ODM-201 (also known as BAY-1841788) is a non-steroidal antiandrogen, specifically, a full and high-affinity antagonist of the androgen receptor (AR), that is under development by Orion and Bayer HealthCare for the treatment of advanced, castration-resistant prostate cancer (CRPC).[2][3]

Relative to enzalutamide (MDV3100 or Xtandi) and apalutamide (ARN-509), two other recent non-steroidal antiandrogens, ODM-201 shows some advantages.[3] ODM-201 appears to negligibly cross the blood-brain-barrier.[3] This is beneficial due to the reduced risk of seizures and other central side effects from off-target GABAA receptor inhibition that tends to occur in non-steroidal antiandrogens that are structurally similar to enzalutamide.[3] Moreover, in accordance with its lack of central penetration, ODM-201 does not seem to increase testosterone levels in mice or humans, unlike other non-steroidal antiandrogens.[3] Another advantage is that ODM-201 has been found to block the activity of all tested/well-known mutant ARs in prostate cancer, including the recently-identified clinically-relevant F876L mutation that produces resistance to enzalutamide and apalutamide.[3] Finally, ODM-201 shows higher affinity and inhibitory efficacy at the AR (Ki = 11 nM relative to 86 nM for enzalutamide and 93 nM for apalutamide; IC50 = 26 nM relative to 219 nM for enzalutamide and 200 nM for apalutamide) and greater potency/efficaciousness in non-clinical models of prostate cancer.[3]

ODM-201 has been studied in phase I and phase II clinical trials and has thus far been found to be effective and well-tolerated,[4] with the most commonly reported side effects including fatigue, nausea, and diarrhea.[5][6] No seizures have been observed.[6][7] As of July 2015, ODM-201 is in phase III trials for CRPC.[3]

ORM-15341 is the main active metabolite of ODM-201.[3] It, similarly, is a full antagonist of the AR, with an affinity (Ki) of 8 nM and an IC50 of 38 nM.[3]
