IntelliPharmaCeutics Announces Issuance Of U.S. And Canadian Patents Covering Aspects Of Its PODRAS Overdose Technology

Published: Dec 21, 2016

TORONTO, Dec. 21, 2016 (GLOBE NEWSWIRE) -- Intellipharmaceutics International Inc. (Nasdaq:IPCI) (TSX:I) ("Intellipharmaceutics" or the "Company"), a pharmaceutical company specializing in the research, development and manufacture of novel and generic controlled-release and targeted-release oral solid dosage drugs, today announced that U.S. Patent No. 9,522,119 and Canadian Patent No. 2,910,865 were issued by the U.S. Patent and Trademark Office  and the Canadian Intellectual Property  Office in respect of “Compositions and Methods for Reducing Overdose”.  The issued patents cover aspects of the Company’s Paradoxical OverDose Resistance Activating System ("PODRAS™") delivery technology, which is designed to prevent overdose when more pills than prescribed are swallowed intact. Preclinical studies of prototypes of oxycodone with PODRAS technology suggest that, unlike other third-party abuse-deterrent oxycodone products in the marketplace, if more tablets than prescribed are deliberately or inadvertently swallowed, the amount of drug active released over 24 hours may be substantially less than expected. However, if the prescribed number of pills is swallowed, the drug release should be as expected.

In April 2015, the United States Food and Drug Administration ("FDA") published Guidance for Industry: Abuse-Deterrent Opioids — Evaluation and Labelingwhich cited the need for more efficacious abuse-deterrence technology.  In this Guidance, the FDA stated, "opioid products are often manipulated for purposes of abuse by different routes of administration or to defeat extended-release properties, most abuse-deterrent technologies developed to date are intended to make manipulation more difficult or to make abuse of the manipulated product less attractive or less rewarding.  It should be noted that these technologies have not yet proven successful at deterring the most common form of abuse—swallowing a number of intact capsules or tablets to achieve a feeling of euphoria."

"The issuance of these patents represents a significant advance in our abuse deterrence technology platform. We believe that the platform has the potential to positively differentiate the Company’s technology from others of which we are aware, and may represent an important step toward addressing the FDA’s concern over the ingestion of a number of intact pills or tablets," said Dr. Isa Odidi, Chief Executive Officer of Intellipharmaceutics. "In addition to its use with opioids, the PODRAS platform is potentially applicable to a wide range of drug products that are intentionally or inadvertently abused and cause harm by overdose to those who ingest them."

On November 25, 2016, the Company announced  that it filed a New Drug Application ("NDA") with the FDA seeking authorization to market its Rexista® abuse-deterrent oxycodone hydrochloride extended release tablets in the 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 60 mg and 80 mg strengths. The issuance of these patents provides the Company the opportunity to accelerate its PODRAS™ development plan by pursuing proof of concept studies in humans. The Company intends to incorporate this technology in an alternate Rexista® product candidate.  There can be no assurance that any Rexista® product candidate will receive FDA approval or that, if approved, it will be successfully commercialized.

About Intellipharmaceutics

Intellipharmaceutics International Inc. is a pharmaceutical company specializing in the research, development and manufacture of novel and generic controlled-release and targeted-release oral solid dosage drugs. The Company’s patented Hypermatrix™ technology is a multidimensional controlled-release drug delivery platform that can be applied to the efficient development of a wide range of existing and new pharmaceuticals. Based on this technology platform, Intellipharmaceutics has developed several drug delivery systems and a pipeline of products (some of which have received FDA approval) and product candidates in various stages of development, including Abbreviated New Drug Applications (“ANDAs”) filed with the FDA (and one Abbreviated New Drug Submission filed with Health Canada) in therapeutic areas that include neurology, cardiovascular, gastrointestinal tract, diabetes and pain.

Intellipharmaceutics also has NDA 505(b)(2) specialty drug product candidates in its development pipeline. These include Rexista® (abuse deterrent oxycodone hydrochloride extended release tablets), based on its proprietary nPODDDS™ novel Point Of Divergence Drug Delivery System (for which an NDA has been filed with the FDA), and Regabatin™ XR (pregabalin extended-release capsules). Our current development effort is increasingly directed towards improved difficult-to-develop controlled-release drugs which follow an NDA 505(b)(2) regulatory pathway. The Company has increased its research and development emphasis towards new product development, facilitated by the 505(b)(2) regulatory pathway, by advancing the product development program for both Rexista® and Regabatin™.  The 505(b)(2) pathway (which relies in part upon the approving agency’s findings for a previously approved drug) both accelerates development timelines and reduces costs in comparison to NDAs for new chemical entities. An advantage of our strategy for development of NDA 505(b)(2) drugs is that our product candidates can, if approved for sale by the FDA, potentially enjoy an exclusivity period which may provide for greater commercial opportunity relative to the generic ANDA route.
