Corium Receives March 11, 2022 PDUFA Date for New Drug Application for ADLARITY® Patch (donepezil transdermal system) for Treatment of Patients with Alzheimer's Disease


BOSTON, Oct. 12, 2021 /PRNewswire/ -- Corium, Inc., a commercial-stage biopharmaceutical company leading the development and commercialization of novel central nervous system (CNS) therapies, announced today the U.S. Food and Drug Administration (FDA) set a Prescription Drug User Fee (PDUFA) target action date of March 11, 2022 for Corium's new drug application (NDA) for once-weekly ADLARITY (donepezil transdermal system), its lead investigational product and a patch formulation of donepezil for the treatment of patients with dementia due to mild, moderate, or severe Alzheimer's disease. If approved, ADLARITY would be Corium's second CNS product approved for the U.S. market in 12 months.

"Having ADLARITY under consideration by the FDA reflects the significant R&D expertise at Corium. With ADLARITY, Corium has leveraged our innovative Corplex technology to improve the most commonly used first-line treatment for patients with Alzheimer's," said Perry J. Sternberg, President and CEO of Corium. "Our team at Corium is committed to addressing the unmet treatment needs for the Alzheimer's community and others impacted by CNS diseases by developing innovative medicines. We look forward to the FDA's decision early next year."

ADLARITY is a transdermal formulation of donepezil made possible by Corium's proprietary Corplextechnology. Corplex enables transdermal therapeutics that incorporate small molecule drugs previously thought incapable of delivery through the skin. The ADLARITY transdermal patch is constructed to be worn for seven days with consistent adhesion, a delivery method that avoids the difficulties associated with daily delivery of an oral medication for patients with significant memory problems. Corium also is developing Corplex for the delivery of drugs to treat patients with other CNS conditions, diseases in other therapeutic areas and consumer products beyond those for which it currently is used.

Donepezil, the most prescribed medication in a class of Alzheimer's drugs known as cholinesterase inhibitors, is the active ingredient in Aricept®. The FDA previously approved donepezil as a once-daily tablet and as an orally disintegrating tablet for the treatment of patients with mild, moderate, or severe forms of the disease. With the slow and steady releasing of donepezil, the ADLARITY transdermal system regularly delivers the drug through the skin, a design meant to avoid gastrointestinal tract absorption and associated side effects. Corium is seeking approval of two transdermal ADLARITY doses capable of delivering, respectively, 5 or 10 milligrams of donepezil daily.

Corium is pursuing the approval of ADLARITY via the FDA's 505(b)(2) regulatory pathway and referencing Aricept data. Corium resubmitted the ADLARITY NDA to address questions asked by the FDA in a July 2020 complete response letter. The resubmitted NDA includes data from three clinical trials conducted following receipt of the FDA letter. 

About Alzheimer's Disease
Alzheimer's disease is a progressive and irreversible brain disorder that lacks a cure. It involves changes in brain tissue including abnormal buildup of proteins as well as loss of neuron function.1 The resulting damage leads to the loss of remembering, reasoning, and thinking abilities. The related behavioral changes include the loss of independence in activities of daily living and self-care.2,3

Globally, more than 55 million people have dementia and Alzheimer's disease may account for 60 to 70 percent of patients, according to the World Health Organization.4 In the United States, an estimated 6.2 million Americans aged 65 and older live with Alzheimer's disease in 2020, but by 2030, the number is projected to increase to 8.2 million, and in 2040, 11.1 million.5,6  The U.S. Centers for Disease Control and Prevention estimates that in 2020, more than 11 million Americans provided an estimated 15.3 billion hours of unpaid care for patients with Alzheimer's disease, a contribution valued at $257 billion.7 Alzheimer's disease is the sixth leading cause of death in U.S. adults.8
