Apalutamide (INN) (developmental code name ARN-509, also JNJ-56021927) is a non-steroidal antiandrogen that is under development for the treatment of prostate cancer.[1] It is similar to enzalutamide both structurally and pharmacologically,[2] acting as a selective competitive antagonist of the androgen receptor (AR), but shows some advantages, including greater potency and reduced central nervous system permeation.[1][3][4] Apalutamide binds weakly to the GABAA receptor similarly to enzalutamide, but due to its relatively lower central concentrations, may have a lower risk of seizures in comparison.[1][3][5] The drug has been found to be effective and well-tolerated in clinical trials thus far,[2][4] with the most common side effects reported including fatigue, nausea, abdominal pain, and diarrhea.[6][3][5] Apalutamide is currently in phase III clinical trials for castration-resistant prostate cancer.[7]

Recently, the acquired F876L mutation of the AR identified in advanced prostate cancer cells was found to confer resistance to both enzalutamide and apalutamide.[8][9] A newer antiandrogen, ODM-201, is not affected by this mutation, nor has it been found to be affected by any other tested/well-known AR mutations.[10]

Apalutamide may be effective in a subset of prostate cancer patients with acquired resistance to abiraterone acetate.[2]
