Apricus Biosciences Confirms Clinical Strategy for Its Novel Treatment for Symptomatic Secondary Hypogonadism Fispemifene

Apricus Expects to Report Top-Line Phase 2b Data in Q1 2016

SAN DIEGO, Dec. 1, 2015 (GLOBE NEWSWIRE) -- Apricus Biosciences, Inc. (Nasdaq:APRI), a biopharmaceutical company advancing innovative medicines in urology and rheumatology, today reaffirmed its regulatory and clinical strategy for the development of fispemifene in response to the Complete Response Letter issued to Repros Therapeutics Inc. (RPRX) by the Food and Drug Administration (FDA). Apricus is developing fispemifene, a SERM (selective estrogen receptor modulator) for the treatment of sexual dysfunction in men with symptomatic secondary hypogonadism.

"Apricus has worked with the FDA to develop our clinical strategy for fispemifene," commented Barbara Troupin, M.D., Chief Medical Officer of Apricus. "For our ongoing Phase 2b study, we developed a protocol that addresses the FDA's suggestions for clearly defining the target patient population, designating clinical benefits which are both important and relevant to the target population, and using symptom-based endpoints aimed at assessing those specific benefits in this population. As a result, we believe we are well-positioned to bring a first-in-class SERM product to the U.S. market."

Apricus expects to report results from the Phase 2b fispemifene trial in the first quarter of 2016 and, if successful, will continue to work closely with the FDA to plan registration studies of fispemifene in 2016.

Phase 2b Trial Design

The Phase 2b proof-of-concept clinical trial is a randomized, double-blind, placebo-controlled, parallel arm, multi-center study in up to 160 hypogonadal men aged 18 to 64 who present with sexual dysfunction related to secondary hypogonadism, or low levels of testosterone. The study will evaluate the safety and tolerability of oral fispemifene, and will assess the effects of treatment on the sexual symptoms using patient reported outcome (PRO) endpoints. The study will also assess relevant pharmacodynamic and pharmacokinetic parameters to evaluate the ability of fispemifene to endogenously increase the serum testosterone level.
