NATESTO® Spermatogenesis Study Final Results Accepted for Presentation at the American Society for Reproductive Medicine 75th Annual Scientific Conference

• Final study results accepted for “Late Breaking Presentation” on October 16, 2019

TORONTO–(BUSINESS WIRE)–Acerus Pharmaceuticals Corporation (TSX:ASP, OTCQB:ASPCF) today announced that the NATESTO^® Spermatogenesis Study results have been accepted for presentation as a “Late-Breaking Abstract” by the American Society for Reproductive Medicine (ASRM). The study results will be presented at the 75^th ASRM Scientific Congress & Expo in Philadelphia, PA October 12-16, 2019.

Dr. Ranjith Ramasamy, MD, Associate Professor and Director of Reproductive Urology at the University of Miami School of Medicine and the study’s principal investigator, will present the data in conjunction with Dr. Thomas Masterson, MD, Fellow in Reproductive Urology at the University of Miami School of Medicine.

Late-breaking abstracts highlight novel and practice-changing studies and will be presented at ASRM’s “Late-Breaking Abstract” session beginning at 10:45 AM ET on Wednesday, October 16, 2019. The NATESTO^® Spermatogenesis Study is one of only six abstracts accepted for presentation by ASRM. Abstracts are accepted for presentation based on the impact of the study findings.

The NATESTO^® Spermatogenesis Study is investigating the impact of NATESTO^® on sperm production and sperm quality parameters. This Phase IV, single-site, prospective study is evaluating hypogonadal men, ages 18 to 55, completing a six-month treatment period with NATESTO^® to restore clinically low serum testosterone levels with the goal of maintaining sperm concentration, motility, and total motile sperm count.

Interim results presented to date demonstrate that almost all subjects completing the six-month treatment period not only had serum testosterone levels return to the normal range, but all measures of semen parameters including sperm concentration, sperm motility, and total motile sperm count (TMSC) remained unchanged through three months and six months of therapy.

No additional information regarding the results from the NATESTO^® Spermatogenesis Study will be available until the data is released on October 16, 2019.
