Aytu BioScience Provides Study Update for Spermatogenesis Study of Natesto (R), the Only FDA-Approved, Nasally-Administered Testosterone Treatment
Interim Results Demonstrated Preservation of Sperm Parameters After Six Months of Treatment with Nasally-Administered Natesto Testosterone Gel
Natesto Spermatogenesis Study Presentation Awarded Presidential Citation at ENDO 2019 Scientific Meeting
ENGLEWOOD, CO / ACCESSWIRE / March 27, 2019 / Aytu BioScience, Inc. (NASDAQ: AYTU), a specialty pharmaceutical company focused on global commercialization of novel products addressing significant medical needs, is providing an enrollment update for the ongoing Natesto Spermatogenesis Study, the Phase 4 clinical trial investigating the impact of nasally-administered Natesto on preservation of fertility parameters. This study is being conducted at the University of Miami’s Department of Urology, and Dr. Ranjith Ramasamy, MD, the Director of Reproductive Urology, is the study’s principal investigator.
To date, 56 patients have been enrolled in the study, and 15 subjects have completed treatment at six months. Interim results published to date demonstrate that all three measured fertility parameters are preserved after three and six months of Natesto treatment.
Additionally, the presentation of the Natesto Spermatogenesis Study was awarded with a Presidential citation at the 101st Annual Endocrine Society Meeting held March 23-26 in New Orleans, LA. Lead author and University of Miami urology chief resident Tom Masterson, MD presented interim data for the ongoing study and received the Presidential citation. The Presidential Poster Competition awards presenting fellows and trainees for research excellence and impact of the research in the field of endocrinology.
The Natesto Spermatogenesis Study is investigating the impact of Natesto, the only FDA approved, nasally-administered testosterone treatment, on sperm production. This 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.
Of the 56 subjects enrolled to date, 43 subjects have completed one month of Natesto therapy, 23 subjects have completed three months, and 15 subjects have completed the full six-month treatment period equivalent to two rounds of spermatogenesis.
Interim results demonstrate that 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 statistically unchanged through three months and six months of therapy.
Traditional testosterone replacement therapy (TRT), as a whole, has been known to decrease gonadotropin levels, diminish sperm production and function, and decrease the natural production of endogenous testosterone in men being treated with TRT. Maintenance of fertility and family planning is an important discussion topic for the more than 2 million men considering testosterone replacement therapy. Therefore, the effect of Natesto possibly minimizing the impact on sperm production would be clinically impactful and novel by providing a safe and effective approach for treating men with hypogonadism.
Josh Disbrow, Aytu BioScience’s Chief Executive Officer commented, ”We congratulate Dr. Masterson, Dr. Ramasamy, and their entire research group for receiving the prestigious Presidential citation at ENDO 2019 for their ongoing work with the Natesto Spermatogenesis Study. Their work surrounding Natesto is exciting, and these data may represent a true paradigm shift in how clinicians treat Low T. We’re encouraged by the positive results to date demonstrating preservation of fertility parameters with Natesto. Further, it is encouraging to see the high level of patient enrollment achieved to date in this novel study. We’re looking forward to observing Dr. Ramasamy’s group’s continued progress with this study and seeing the final results this summer.”
The entire study group is expected to complete the full six-month treatment period during summer 2019, and the full data will be reported soon thereafter.
Interim results were previously published in August 2018 in European Urology Focus.
