Lexaria Examining Potential Therapeutic Use of DehydraTECH-CBD in Dementia

KELOWNA, BC / ACCESSWIRE / November 10, 2022 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces that study program DEM-A22-1 is expected to begin on November 15, 2022. This is Lexaria's first-ever study to investigate whether its patented DehydraTECH-processed cannabidiol ("CBD") may potentially have therapeutic utility against dementia.

Lexaria has previously evidenced the efficacy of DehydraTECH-CBD in human hypertension studies with no serious side effects. Clinical studies have established that there are connections between hypertension and dementia: individuals who have high blood pressure are more likely to develop vascular dementia, which is the second most common form of dementia following Alzheimer's disease. "Vascular dementia is caused by reduced blood flow to the brain, which starves brain cells of the oxygen and nutrients they need to function correctly". Others have conducted research evidencing therapeutic potential of cannabinoids including CBD in a variety of neurodegenerative diseases.

Lexaria has previously demonstrated in animal studies that DehydraTECH-CBD crosses the blood brain barrier ("BBB") much more effectively than originally thought possible. Given the propensity of DehydraTECH-CBD to cross the BBB; the established fact that DehydraTECH-CBD lowers human blood pressure; and the fact that CBD is known to act with vasodilation properties, Lexaria is excited to investigate whether DehydraTECH-CBD might have some positive effect on dementia.


Study DEM-A22-1 is a dose-ranging, two-month program in a total of 32 Long Evans rats that will be dosed with DehydraTECH-CBD. The study is a novel object recognition test which is widely used to assess memory in rodents, and is being utilized to investigate whether CBD enables cognitive performance enhancements in this model, potentially of utility in dementia treatment. Extensive use of cameras will be used to monitor and evaluate animal behaviour.

Study DEM-A22-1 will be undertaken by a leading, third-party testing laboratory located in Canada. The laboratory work is expected to complete in late January 2023 with data and reporting to follow thereafter. Depending on the outcomes, study DEM-A22-1 may be followed by additional investigations potentially including DehydraTECH-processed nicotine as another agent known to enhance cognitive performance when delivered effectively. Lexaria will provide further updates and any relevant material findings in due course from this study as they become available.


Dementia is a term describing loss of cognitive abilities related to memory, language, problem solving abilities and more. Alzheimer's disease is the most common type of dementia, followed by vascular dementia. According to the World Health Organization, 55 million people are currently suffering from dementia with roughly 10 million additional people being diagnosed each year.

Drugs used to treat dementia represented a $15.5 billion market in 2021, expected to double to a $32.3 billion annual market by 2030, in part due to the generally aging populations. Certain trials are underway to also investigate the use of nicotine for possible utility related to dementia, where some clinical success has already been reported.

Although Lexaria's current study DEM-A22-1 is utilizing only DehydraTECH-CBD in order to discover any effects that CBD might have on dementia, Lexaria is considering additional future studies that might utilize either nicotine alone, or nicotine in combination with CBD. Results from study DEM-A22-1 will be reported as soon as available, likely in April 2023.
