Positive Preclinical Results and Patent Allowed for Aequus' Once-Weekly Transdermal Aripiprazole


VANCOUVER, BRITISH COLUMBIA--(Marketwired - July 23, 2015) - Aequus Pharmaceuticals Inc. ("Aequus") (TSX VENTURE:AQS) announced today they have successfully completed an in vivo feasibility study with AQS-1301, a proprietary transdermal patch containing the psychoactive drug, aripiprazole. A pharmacokinetic study was conducted in animals in order to estimate the effectiveness of the novel formulation in delivering therapeutic amounts of the drug over a 7 day period.

"We were very pleased that the patch delivered drug at a very consistent rate over the 7 day period. This is an essential feature of a once-weekly therapeutic," said Douglas Janzen, Chairman and CEO of Aequus. Estimates from the experimental data predict that therapeutic levels of aripiprazole will be achieved with a reasonably-sized patch in human clinical trials expected to begin later this year.

Aequus also announced it has received a Notice of Allowance from the U.S. Patent Trademark Office (USPTO) for a pharmaceutical formulation patent application that covers AQS-1301, a once-weekly transdermal formulation of aripiprazole. The patent to be issued from this allowed application is titled "Aripiprazole compositions and methods for its transdermal delivery". Similar applications have been filed with the European Patent Office (EPO) and the Patent Cooperation Treaty (PCT). This is the first approved of several patent applications filed covering AQS-1301, which Aequus has exclusively licensed from Transdermal Research Pharm Laboratories.

"We will continue to be focused on building on our patent portfolio as we further investigate AQS-1301," said Anne Stevens, COO and Director of Aequus. "Today's events greatly support the commercial potential of this product which we believe could provide increased benefits to patients in need of this important drug."

The oral, once-daily formulation of aripiprazole is currently marketed under the trade name Abilify®, which is an atypical antipsychotic used for the treatment of bipolar I disorder, schizophrenia, irritability associated with autistic disorder, and major depressive disorder. Abilify® is a market leader in the U.S., and Aequus believes it has limitations due to its daily dosing regimen which is associated with a high rate of non-adherence and relapse. Aequus' proposed transdermal, once-weekly aripiprazole patch is designed to consistently deliver aripiprazole over a seven-day period at levels comparable to currently marketed once-daily formulations. By delivering aripiprazole over seven days in a comfortable, convenient and easy-to-use weekly patch, AQS-1301 is intended to promote enhanced patient compliance.
