Provides Composition of Matter Coverage to 2037
MENLO PARK, Calif., June 13, 2018 (GLOBE NEWSWIRE) -- Corium International, Inc. (NASDAQ:CORI), a commercial stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty transdermal products, announced today that the United States Patent and Trademark Office (PTO) has issued a cornerstone patent related to the company’s Corplex Donepezil Transdermal Delivery System (TDS), a once-weekly patch that delivers the most commonly prescribed medication for Alzheimer’s patients. U.S. Patent No. 9,993,466 provides coverage of the drug product and its unique design features, including composition elements that achieve a sustained, controlled and effective delivery of donepezil across the skin for the 7-day wear period. In addition, the PTO recently issued a notice of allowance on another patent related to methods of transdermal delivery of donepezil using the product described in U.S. Patent No. 9,993,466. As previously announced, the Corplex Donepezil TDS has achieved positive results in clinical bioequivalence testing, and Corium is preparing to file a New Drug Application for the product based on these results.
"Our novel Corplex TDS design and formulation technologies were enabling for the once-weekly transdermal delivery of Donepezil," said Parminder "Bobby" Singh, Ph.D., Chief Technology Officer and Vice President, R&D at Corium, and a co-inventor on the patent. "The issuance of this patent highlights our innovation in the transdermal delivery of molecules such as donepezil that have previously been very challenging to transport across the skin with traditional patch technologies."
The new patent is eligible for listing in the U.S. FDA Orange Book, and its life extends at least to July 2037. It is the first to issue of a series of pending Corium patent applications relating to various aspects of Corplex Donepezil, as well as similar products.
About Alzheimer's Disease and Donepezil
Alzheimer's disease is a progressive brain disorder in which the brain cells degenerate and die, causing a steady decline in memory and mental function. According to the Alzheimer’s Association, an estimated 5.7 million Americans are living with Alzheimer's disease in 2018; by 2050, this number is projected to rise to 13.8 million. Alzheimer's disease is the most common cause of dementia among older adults. Dementia ranges in severity from mild, when it is just beginning to affect a person's functioning, to moderate, and severe, when the person must depend on others for the basic activities of day-to-day life.
Donepezil (the active ingredient in Aricept®) is the most widely prescribed medication in a class of Alzheimer's drugs known as cholinesterase inhibitors, and is approved for the treatment of mild, moderate and severe disease. Donepezil is currently only available in tablet or orally disintegrating tablet form, each administered once daily, presenting compliance challenges for family members and caregivers who cannot rely on patients to consistently take their daily tablets, and is known to cause gastrointestinal side effects, including nausea, vomiting and loss of appetite.
Corium's Corplex system is a novel commercial-stage platform technology designed to broadly enable the transdermal delivery of small molecules, many of which have not previously been amenable to transdermal delivery. Corium's Corplex technology has been successfully commercialized in Procter & Gamble's Crest® Whitestrips products, and is being utilized in therapeutic products under development.
Corium International, Inc. is a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty pharmaceutical products that leverage the company's broad experience with advanced transdermal and transmucosal delivery systems.
