Lexaria’s DehydraTECH-CBD Lowers Blood Glucose Levels in Diabetes Animal Study

• Blood glucose levels reduced by 19.9% with DehydraTECH-CBD
• Improvements in kidney function also demonstrated

KELOWNA, BC / ACCESSWIRE / June 16, 2023 / Lexaria Bioscience Corp. (Nasdaq:LEXX)(Nasdaq:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms is pleased to report upon additional findings from its diabetes animal study DIAB-A22-1, and also provide updates on two other applied R&D programs.

Diabetes: DIAB-A22-1

As announced on March 2, 2023, Lexaria completed initial testing using DehydraTECH-CBD in its diabetes animal model study that produced three positive outcomes including weight loss in obese diabetic-conditioned animals, together with improved triglyceride and cholesterol levels. Following this, Lexaria undertook a further round of analysis to explore additional study outcomes, including the use of an alternate blood glucose assay detection system with higher detection sensitivity than was used in the initial testing round.

Using the Antech hexokinase blood chemistry test panel methodology, Lexaria discovered that blood glucose levels were statistically significantly lowered by 19.9 ± 7% in the obese diabetic-conditioned animals treated with the DehydraTECH-CBD 30 mg/Kg dose (yellow bar above) (*p<0.05) compared to the obese vehicle control animals. This appears to be a new discovery of a property not generally known to be associated with generic CBD treatment.

Kidney function was also evaluated compared to the vehicle control animals by examination of the levels of blood urea nitrogen ("BUN"), creatinine, and assessment of the BUN/creatinine ratio. BUN levels were reduced by 27.9% +/- 5% (***p<0.001) in the obese animals receiving DehydraTECH-CBD. Creatinine levels were also improved with a 16.8% +/-7% increase in the obese animals receiving DehydraTECH-CBD, although this improvement was not statistically significant.

Astonishingly, the calculated BUN/creatinine ratio in the obese animals being treated with DehydraTECH-CBD returned to a healthy range nearly equal to that of the lean animals, with a 55.1% +/-16% reduction (*p<0.05) (yellow bars above indicate DehydraTECH-CBD treatment). This may reflect an effect of DehydraTECH-CBD to correct abnormal kidney function in this animal model as another prospective benefit in treating pathological conditions commonly associated with diabetes.

DehydraTECH-CBD's ability to reduce blood sugar levels in animals is extremely encouraging and certainly warrants additional investigation. According to the Center for Disease Control, managing your blood sugar levels is important to avoid diabetes-related conditions such as vision loss, heart disease, and kidney disease. Generic CBD has not, in general, been found to be effective in controlling blood sugars and the Company has not yet discovered whether DehydraTECH-CBD might be effective in blood-sugar control in humans.

Dementia: DEM-A22-1

As announced on November 10, 2022, study DEM-A22-1 was undertaken in thirty-two Long Evans rats using the established novel object recognition test ("NOR"), which is used to assess memory in rodents, in order to investigate whether DehydraTECH-CBD enables any pro-cognitive performance enhancements in this model, potentially of use in dementia treatment.

The findings from this study were generally unremarkable and several unexpected study complications may have muted efficacy distinction ability. Most notably, the aged rats where cognitive impairment was expected to be most obvious did not, in fact, adequately exhibit this impaired tendency, making "improvements" difficult to measure. Also, animals in the high dose DehydraTECH-CBD cohort exhibited reduced locomotor activity, which may have indicated that treatment at this level produced sedative activity, also masking any prospective cognitive improvement. Together, these inconclusive results may point to required study design improvements necessary for a more concrete set of results.

While this research did not produce any notable outcomes, Lexaria now recognizes that previous research by other investigators using CBD in this animal model has required dosing over a much longer duration (over a period of several weeks in order to demonstrate NOR enhancement), than Lexaria has thus far evaluated-. Lexaria will consider this if further testing is considered in future, potentially also including DehydraTECH-processed nicotine, as previously announced, as another agent known to enhance cognitive performance when effectively delivered.

Epilepsy: EPIL-A21-1

As announced on November 29, 2022, Lexaria successfully completed two parts of its EPIL-A21-1 study program designed to evaluate the effectiveness of its DehydraTECH-CBD compared to one of the world's leading anti-seizure medications, Epidiolex®, in reducing seizure activity using an established, vehicle-controlled, acute animal seizure model induced by electrical stimulation ("MES"). The findings from this work appear to demonstrate that DehydraTECH-CBD had effectiveness at lower doses and with greater rapidity than Epidiolex®.

Since that time, Lexaria has also completed a final MES study under its EPIL-A21-1 program designed to establish an ED50 (i.e., the dose required to achieve seizure inhibition in 50% of the animals tested) for DehydraTECH-CBD in this animal model, where ED50 determination is a common performance metric in preclinical animal studies for developmental therapeutics. This ED50 study was designed with an objective to hopefully corroborate Lexaria's prior MES experimental findings. Lexaria is pleased to confirm that the outcome demonstrated that DehydraTECH-CBD was most effective at a dose of 75 mg/Kg, also as previously reported from the initial round of work in this animal model which compared favourably to Epidiolex® that generally required a higher dose of 100 mg/Kg to achieve comparable findings.

About DehydraTECH

DehydraTECH is a patented drug delivery formulation and processing platform technology Lexaria has developed and is investigating for a variety of beneficial molecules. DehydraTECH is designed to improve the way active molecules enter the bloodstream upon oral ingestion. DehydraTECH has also demonstrated enhanced delivery of certain active molecules into brain tissue, which Lexaria believes to be of particular importance for centrally active compounds. Lexaria has also developed DehydraTECH formulations for other applications demonstrating superior bio-absorption when administered intraorally and topically.
