Acerus Announces Publication of Results for NATESTO® Spermatogenesis Study in Journal of Urology

Acerus Pharmaceuticals Corporation (TSX:ASP, OTCQB:ASPCF) (“Acerus” or the “Company”) today announced the acceptance of the NATESTO® Spermatogenesis Study results for publication in an upcoming issue of the Journal of Urology.

The single-institution, open-label, single-arm trial was conducted between November 2017 and September 2019 at the University of Miami's Department of Urology. The study concluded that NATESTO^® was found to be both effective in restoring hypogonadal men to normal testosterone levels, while also simultaneously improving both erectile function and quality of life. Importantly, gonadotropin hormones remained within normal ranges and semen parameters were preserved through 6 months of treatment in 95% of men.

“Testosterone therapy is typically considered as a contraceptive and contraindicated in men interested in fertility. However, results from our clinical trial present a paradigm shift in the treatment of men with testosterone deficiency. The short-acting property of NATESTO® likely preserves gonadotropins and sperm parameters as compared to other commonly used testosterone therapies that are typically long-acting,” said the study’s principal investigator Dr. Ranjith Ramasamy, MD, Associate Professor and Director of Reproductive Urology at the University of Miami School of Medicine.

The study authors estimate that up to 16% of men being prescribed testosterone therapy (TTh) are under 39 years old. The most commonly prescribed testosterone therapies, injections and topical gels, can impair semen parameters and can cause azoospermia (absence of sperm in the semen) in up to 2/3^rds of men. Therapies such as clomiphene citrate, a selective estrogen receptor modulator (SERM), are widely used off-label to preserve spermatogenesis while simultaneously increasing testosterone. Many of these off-label products can have several adverse reactions; therefore, identifying alternatives to increase testosterone in men without impacting gonadotropin levels and sperm parameters is paramount.

The Phase IV clinical trial investigating the impact of nasally administered NATESTO® on restoration of testosterone and preservation of fertility parameters evaluated 44 subjects through 3 months, and 33 subjects through 6 months of treatment. Mean testosterone increased from 231 ng/dL to 652 ng/dL after 6 months of NATESTO® treatment. There was improvement across all domains of erectile function (based in IIEF-15), with particularly significant improvements in sexual desire and overall satisfaction. Additionally, sperm concentration, sperm motility, and total motile sperm count were maintained through 6 months of NATESTO® treatment. Key data are summarized in the following table.

“We now have clinical evidence demonstrating that a testosterone therapy has been proven to restore serum testosterone levels while maintaining gonadotropin hormones within the normal range, while also maintaining sperm concentration, motility, and total motile sperm count," said Ed Gudaitis, President and Chief Executive Officer of Acerus. “This clearly distinguishes NATESTO® from all other testosterone replacement therapies and can create a clinical paradigm shift across the spectrum of male reproductive health. Publication of the study in a high impact journal like the Journal of Urology indicates the clinical significance of these findings.”

Acerus will evaluate options with respect to NATESTO® product labeling claims as it relates specifically to these study results and data.
