Those same three groups (E, F, and G) achieved mostly superior blood sugar control results as compared to the Placebo Group throughout the duration of the Study and mostly superior blood sugar control results as compared to the SOC Group at the 4^th and 8^th week durations, but inferior results compared to the SOC Group by the 12^th week duration.

Most of the DehydraTECH-CBD formulation groups (A, B, C, and D) achieved their best weight-control performance during the final 4 weeks of the Study, implying that a longer-term study may be required to determine the full extent of weight loss possible with DehydraTECH-CBD. Those same four formulation groups (A, B, C, and D) all achieved superior blood sugar control performance than the Placebo Group at the 8^th and 12^th week, and mostly superior blood sugar control performance to SOC Group at the 4^th and 8^th week periods. The SOC Group achieved its best blood sugar control in the final four weeks of the study.

Animal Weights (grams)

Notes

- Groups A through D were different DehydraTECH-CBD compositions
- Groups E and F were reformulated Rybelsus DehydraTECH compositions
- Groups G and H used pure GLP-1 drugs (semaglutide and liraglutide respectively) in DehydraTECH compositions
- Recalculations led to slight changes from earlier reported data
- Group K received only water as a placebo control versus the other groups that received water+drug at dosing
- Group L received unadulterated Rybelsus® with no DehydraTECH processing

Both of the combination drug groups (I and J) achieved superior body-weight control performance to both the Placebo Group and SOC Group at the 12^th week, but inferior blood sugar control across most time points.

Blood Sugar Levels (mmol/L)

The two groups of the Study (I and J), that combined doses of either DehydraTECH-semaglutide or DehydraTECH-liraglutide with DehydraTECH-CBD were generally worse performers than either of the drugs alone with respect to blood sugar control, although, regarding reduced body-weight control, they were nonetheless generally superior to both the Placebo Group and the SOC Group.

"Overall, the findings from our animal study showed benefits of DehydraTECH-processing with all drugs studied alone or in combination relative to the Rybelsus® control formulation," said John Docherty, President & CSO of Lexaria Bioscience Corp. "This Study is strongly supportive of our plans to advance to our upcoming Phase 1b chronic dosing clinical study in Australia through our Australian subsidiary, Lexaria (AU) Pty Ltd, which we have endeavoured to design to allow for maximum impacts upon blood glucose and body weight control while also evaluating safety and tolerability in humans."

All body weight and blood glucose findings from the Study, including from the SOC Group and Placebo Group, have now been received. Additional data processing and interpretation remains, including the analyses of brain and blood absorption pharmacokinetic results and more. Lexaria has not yet received this data from the third-party lab and will report upon same when results are available.

About the Study
The Study model selected - diabetic Zucker rates with unlimited food and water provided 24 hours per day - is a more stringent model design than that used in most studies primarily focused on weight loss. As such, it is expected that weight loss results within this Study would be less than other third-party weight loss studies and that weight gain would not be unexpected. The primary rational for conducting this Study was to perform a relative comparison of many different formulations and test for relative differences between them in a diabetic state purposefully perpetuated for the duration of the Study. Future animal work that is primarily focused on weight loss - already under design by Lexaria - will use a study model more typical of weight loss studies that do not provide 24-hour unlimited food and water.

Study WEIGHT-A24-1 was completed using diabetic, pre-conditioned Zucker rats. Each group of the Study was dosed for a 12-week period following the initial acclimation period. During the Study, over 1,500 blood plasma samples were collected from the total starting rat population of 72 animals for purposes of detailed PK drug delivery analyses. Because of the small animal population in each Study group, statistical significance was not necessarily expected - though achieved in some instances - and commentary on apparent trends has been noted. Body weight and blood glucose readings were taken prior to Study start continuing at regular intervals during and at conclusion of the dosing period. Brain tissue is also in the process of being analysed to help determine whether DehydraTECH processing results in higher brain absorption than non-DehydraTECH groups, as Lexaria has evidenced numerous times in previous animal studies. The Study also included a comprehensive battery of liver and kidney function testing and blood chemistry analyses that remain to be analysed and reported. LC-MS/MS and other techniques were used to analyse samples.

About Lexaria Bioscience Corp. & DehydraTECH
DehydraTECH™ is Lexaria's patented drug delivery formulation and processing platform technology which improves the way active pharmaceutical ingredients (APIs) enter the bloodstream through oral delivery. Since 2016, Lexaria has developed and investigated DehydraTECH with a variety of beneficial molecules in oral and topical formats. DehydraTECH has repeatedly demonstrated the ability to increase bio-absorption and has also evidenced an ability to deliver some drugs more effectively across the blood brain barrier, which Lexaria believes to be of particular importance for centrally active compounds. Lexaria operates a licensed in-house research laboratory and holds a robust intellectual property portfolio with 46 patents granted and many patents pending worldwide.
