Intellipharmaceutics Announces FDA Acceptance for Filing of NDA for Rexista (oxycodone hydrochloride extended release) Abuse Deterrent Opioid Analgesic
TORONTO, Feb. 02, 2017 (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 the U.S. Food and Drug Administration ("FDA") has accepted for filing the Company's previously-announced New Drug Application ("NDA") 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 FDA has determined that the Company's application is sufficiently complete to permit a substantive review, and has set a target action date under the Prescription Drug User Fee Act ("PDUFA") of September 25, 2017.
Rexista is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. The submission is supported by pivotal pharmacokinetic studies that demonstrated that Rexista is bioequivalent to OxyContin® (oxycodone hydrochloride extended release). The submission also includes abuse-deterrent studies conducted to support abuse-deterrent label claims related to abuse of the drug by various pathways, including oral, intra-nasal and intravenous, having reference to the FDA's "Abuse-Deterrent Opioids — Evaluation and Labelling" guidance published in April 2015.
The abuse-deterrent properties incorporated into Rexista are designed to make the product unlikable and discourage or make it more difficult to manipulate for the purpose of abuse or misuse via common routes of administration including: ingestion following chewing, licking or crushing; insufflation; inhalation; or injection. If approved, Rexista may be the only abuse-deterrent oxycodone product with properties that may provide early warning of drug abuse if the product is manipulated or abused. The Company previously announced the results of a food effect study which showed that Rexista can be administered with or without a meal (i.e., no food effect), providing another point of differentiation from currently marketed oral oxycodone extended release products.
The CEO of Intellipharmaceutics, Dr. Isa Odidi, said, "The acceptance of filing of our NDA for Rexista represents an important step towards the commercialization of a potentially best—in-class abuse-deterrent oxycodone hydrochloride extended release product. We look forward to working with the FDA during their review of our NDA submission."
There can be no assurance that we will not be required to conduct further studies for Rexista, that the FDA will ultimately approve the NDA for the sale of Rexista in the U.S. market, or that it will ever be successfully commercialized.
More About Rexista
Our Rexista (abuse deterrent oxycodone hydrochloride extended release tablets) NDA product candidate is intended as an abuse and alcohol-deterrent controlled-release oral formulation of oxycodone hydrochloride for the relief of pain. The Rexista long-acting formulation of oxycodone is intended to present a significant barrier to tampering when subjected to various forms of physical and chemical manipulation commonly used by abusers. It is also designed to prevent dose dumping when inadvertently co-administered with alcohol. Dose dumping is the rapid release of an active ingredient from a controlled-release drug into the blood stream that can result in increased toxicity, side effects, and a loss of efficacy. Dose dumping can result by consuming the drug through crushing, taking with alcohol, extracting with other beverages, vaporizing or injecting. In addition, when crushed or pulverized and hydrated, the proposed extended release formulation is designed to coagulate instantaneously and entrap the drug in a viscous hydrogel, which is intended to prevent syringing, injecting and snorting. Our Rexista formulation is difficult to abuse through the application of heat or an open flame, making it difficult to inhale the active ingredient from burning. Our Rexista formulation contains a blue dye that is emitted once the tablet is tampered with or crushed, and may act as a deterrent to a user who attempts to abuse it orally or via the intra-nasal route.
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 Application ("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.
