Following review of Corium's pre-IND submission, which included summary results from a Phase 1 pharmacokinetic (PK) study of the product candidate, the
"We are pleased with the FDA's positive feedback on our bioequivalence-based clinical development plan," said
"We look forward to advancing our once-weekly Alzheimer's products through clinical trials, and pursuing a streamlined regulatory pathway. These new transdermal therapeutics are designed to deliver drugs that collectively address an estimated 90% of the current market, and have the potential to improve the lives of patients and their caregivers."
Corium recently reported results of studies on its optimized formulation of Corplex Memantine, which demonstrated delivery of the required dose of memantine over seven days in a pig study while also indicating acceptable skin tolerability. In preparation for a pilot BE trial, the company next plans to conduct a human PK study of this optimized formulation in healthy subjects to confirm skin tolerability and sustained delivery over one week.
Bioequivalence clinical studies are designed to assess the biological equivalence of pharmaceutical products based on the similarity of their PK profiles to those of already-approved drugs, and are generally performed in healthy subjects. These studies are relatively short in duration of treatment, and provide a development path that is substantially less costly and more streamlined compared to standard clinical development programs.

About Alzheimer's Disease and Memantine
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. An estimated 5.1 million Americans suffered from Alzheimer's disease in 2015; by 2025, this number is estimated to reach 7.1 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.
Memantine (the active ingredient in Namenda®) is one of the most widely prescribed medications for the treatment of moderate to severe dementia of the Alzheimer's type. Memantine is the only
Memantine and donepezil (the active ingredient in Aricept®) together represent approximately 90% of the units sold for the treatment of Alzheimer's disease in the United States.
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. Corplex advanced transdermal and transmucosal systems are broadly adaptable for use in multiple drug categories and indications, and
have the potential to reduce quantities of active ingredient utilized in transdermal products. Additionally, Corplex transdermal patches can enable efficient drug delivery, and adhere to either wet or dry surfaces for an extended period of time. Corium's Corplex technology has been successfully commercialized in Procter & Gamble's
