ENGLEWOOD, Colo., Nov. 30, 2016 /PRNewswire/ -- Aytu BioScience, Inc. (OTCQX: AYTU), a specialty pharmaceutical company focused on global commercialization of novel products in the field of urology, today announced the summary of findings that demonstrated significant clinical improvements in erectile function and mood in hypogonadal men treated with Natesto® nasal testosterone gel (NTG). Natesto, Aytu's FDA-approved nasal testosterone gel, was launched in late July 2016.
The multi-center Phase 3 study, which was conducted in the U.S., investigated the safety and efficacy of Natesto nasal testosterone gel administered intranasally to 306 men. Male hypogonadism is a clinical syndrome resulting from failure of the testes to produce physiologic levels of testosterone due to disruption of the hypothalamic-pituitary-gonadal axis and is often characterized by mood disturbances, reduced energy levels, and impaired sexual function. This prospective study quantified observed improvement in these key clinical parameters among men taking Natesto.
The study's investigators reported, "NTG achieves large, clinical improvements in erectile function and mood within 30 days of initiating treatment, with the added bonus of improvements in sexual desire. NTG is a safe, effective, and unique form of testosterone therapy and is approved for use in the United States." The results of this study are expected to be presented at an upcoming scientific conference.
"This study further validates the safety and efficacy of Natesto, the only FDA-approved nasally administered testosterone replacement therapy and demonstrates clear improvements in many of the physiologic and psychological effects often experienced by men with hypogonadism," said Josh Disbrow, Chief Executive Officer of Aytu BioScience, Inc. "Specifically, for the first time this study showed that, due to Natesto's unique pharmacokinetic profile, men experiencing mood disturbances, reduced energy levels, and impaired sexual function saw improvements in these parameters in as little as 30 days following the initiation of treatment with Natesto, with durable improvements that lasted through the duration of this study."
The study was a 90-day, randomized, open-label, dose-ranging study in hypogonadal men with sequential safety extensions out to 1 year. Natesto (125 uL/nostril, 11.0mg testosterone/dose) was self-administered using a multiple-dose dispenser either twice daily (BID) or 3 times a day (TID) for a total dose of 22.0mg or 33.0mg, respectively. Titration was performed based on blood levels to achieve the eugonadal range (300 -1050 ng/dL). Erectile function and mood were assessed at baseline (day 0), and 30 day intervals through the 90-day treatment period using the International Index of Erectile Function (IIEF) and Positive and Negative Affect Schedule (PANAS), respectively.
Treatment with Natesto led to statistically significant improvements in each of the 5 domains of erectile function (F(3,813) = 83.96 p < .001). Most of the benefit was evident by Day 30 (t = -9.8714, df = 288, p-value < .001). Similar to erectile function, NTG produced clinically and statistically significant improvements in mood (PANAS) by Day 30, with continued improvements seen through study completion.
