Fispemifene (INN, USAN) (developmental code name HM-101) is a nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group that was developed for the treatment of male hypogonadism but was abandoned and never marketed.[1][2][3] It reached phase II clinical trials for this indication before development was terminated in March 2016.[1] The drug failed to achieve statistical significance on key effectiveness endpoints in clinical trials and was discontinued by its developer for strategic reasons.[1]
