EPI-506 (developed by Essa Pharma; structure undisclosed as of 2015)[1] is an experimental antiandrogen in phase I/II development for prostate cancer.[2] It is the successor of EPI-001 and targets the N-terminal domain of the androgen receptor (AR). This mechanism of action is believed to allow the drug to block signaling from the AR and its splice variants.[3][4] EPI-506 is a prodrug of EPI-002, one of the four stereoisomers of EPI-001.[5]
