TORONTO--(BUSINESS WIRE)-- Acerus Pharmaceuticals Corporation (TSX:ASP) today announced the Health Canada approval of NATESTO™, the first and only nasal gel for testosterone replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone (hypogonadism).1

NATESTO™ is the lowest dose testosterone gel replacement therapy to be approved in Canada, with the majority of men achieving normal testosterone levels in a Phase III study. In addition, NATESTO™ demonstrated significant improvements in erectile function, intercourse satisfaction, orgasmic function, sexual desire, overall satisfaction and positive mood versus baseline.

The product utilizes an innovative, bioadhesive nasal gel technology, allowing for convenient, ‘no-touch’ administration within seconds, rapid absorption and reduced risk of secondary transference to women and children. NATESTO™ has a recommended twice-daily starting dose, which can be adjusted up to a three times daily dose if needed.1

“NATESTO™ addresses many of the gaps with current testosterone replacement therapies,” said Tom Rossi, President and Chief Executive Officer of Acerus. “Health Canada’s approval of NATESTO™ is a momentous event for Acerus, as it represents the opportunity to introduce a unique and novel option for the treatment of men with hypogonadism.”

The prescription testosterone replacement market in Canada represents approximately $70M in sales with stable growth over the past few years. It is estimated that hypogonadism affects approximately 40% of men aged 45 or older2, although less than 5% of these men are actually diagnosed and treated for the condition.3

“The approval of a new testosterone nasal gel formulation increases the number of options available for Canadian men with hypogonadism,” stated Dr. Alvaro Morales, Emeritus Professor of Urology, Queen’s University and Chair, Canadian Men’s Health Guidelines Task Force on Testosterone Deficiency. “The low dose of testosterone required, as documented in the multicentre clinical trial conducted in the United States, and the reduced risk of secondary transfer are interesting features of this preparation.”

NATESTO™ is expected to be commercially available in Canada by mid-2016.

About the NATESTO™ Phase III Study

NATESTO™ was evaluated in a multicentre, open-label, 90-day treatment period followed by two sequential safety extension periods of 90 and 180 days that enrolled 306 hypogonadal men, with a mean age of 54 years (range 28-80 years). During the initial treatment period (Days 1-30), 228 patients and 78 patients were treated with 22 mg and 33 mg of testosterone daily, respectively. On Day 45 of the trial, patients were maintained at the same dose or were titrated to three times a day, based on an assessment of 24-hour average serum testosterone concentration. At Day 90, the majority of patients had met the primary endpoint with an average serum total testosterone concentration within the normal range.

Secondary endpoints included assessments of sexual function and mood. Treatment with NATESTO™ produced significant improvements from baseline in erectile function, intercourse satisfaction, orgasmic function, sexual desire and overall satisfaction. In addition, the overall mean summary scores showed a significant increase in positive mood versus baseline.

The incidence of adverse events with NATESTO™ was low. Prostate-specific antigen (PSA) showed a modest increase, consistent with small increases in dihydrotestosterone (DHT) and DHT/T levels. All of these findings are suggestive of an excellent safety profile. NATESTO™ was well-tolerated and well-accepted.1
