Natesto ''MY-T study'' - First Study to Demonstrate Improvement of Low T Symptoms in Men After Switching to Natesto from Topical Testosterone Gels

ENGLEWOOD, CO / ACCESSWIRE / March 19, 2019 / Aytu BioScience, Inc. (NASDAQ: AYTU), a specialty pharmaceutical company focused on global commercialization of novel products addressing significant medical needs, announced two recent publications summarizing findings from the Phase 4, Natesto® ''MY-T study.'' The MY-T study is the first clinical trial documenting that patients' hypogonadal symptoms improved after switching to Natesto from a topical testosterone gel. Further, the results confirmed the majority of patients prefer Natesto over topical testosterone gels and had higher levels of treatment satisfaction.

The MY-T study was a prospective, multi-centered, open-label study investigating symptom improvement and patient satisfaction with Natesto treatment in subjects that have previously been on topical testosterone therapy, and those that were naïve to testosterone treatment. The original articles are entitled, ''MY-T study: Symptom-based titration decisions when using testosterone nasal gel, Natesto®'' and ''The MY-T study: Patient satisfaction and preference.''

The two manuscripts were recently e-published ahead of print in the Canadian Urologic Association Journal, and the lead author is Jay Lee, MD, Department of Surgery, Division of Urology, University of Calgary.

This clinical trial is the first to document patient preference of hypogonadal men previously treated with topical testosterone gel (for at least three months), before being switched to the Natesto intranasal application. Twenty-four testosterone-naïve and 93 testosterone-experienced hypogonadal men (total n = 117) were treated with Natesto for either 90 or 120 days. Hypogonadal symptoms were improved by 15% (p < 0.0001) through 90 days of Natesto treatment for all treatment groups.

The testosterone-experienced men were given a treatment satisfaction questionnaire immediately prior to ending their topical testosterone gel treatment, and then subsequently upon switching to Natesto. Within 30 days of beginning Natesto treatment (and continuing through the full treatment period), there was a 20% increase in how ''effective'' the subject felt Natesto was compared to the topical gel. Additionally, there was a 30% increase in how ''convenient'' the subject felt Natesto was compared to the previously used topical gel.

Overall, 67.2% of Natesto-treated men agreed or strongly agreed that they preferred Natesto over topical testosterone gel. Further, the testosterone experienced subjects reported ease of use, convenience, efficacy/effectiveness, and travel friendliness as primary ''likes'' of the Natesto therapy.

The MY-T study's authors concluded, ''For patients switching from a topical medication to [Natesto] testosterone nasal gel (TNG), effectiveness, convenience and symptoms all demonstrated significant improvements indicating that the divided dose, ultradian profile with TNG is at least, and possibly more, efficacious than the steady state profile provided by topical testosterone. When followed-up 30 days post-treatment, the majority of patients in this study reported having made the switch to TNG as their preferred choice of medication for testosterone replacement.''

The MY-T study was supported by Acerus Pharmaceuticals.

Aytu BioScience is supporting an investigator-initiated trial studying Natesto's effects on serum testosterone levels, gonadotropin levels, and semen parameters to assess Natesto's ability to increase testosterone levels while preserving male fertility parameters.
