DehydraTECH-liraglutide is outperforming DehydraTECH-semaglutide
Select DehydraTECH-CBD formulations appear to continue to outperform DehydraTECH-semaglutide
KELOWNA, BC / ACCESSWIRE / August 22, 2024 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces that it has received and can now report on 8-week body weight results from ongoing animal study WEIGHT-A24-1 (the "Study").
This Study is the only study carried out anywhere in the world today, to evaluate the relative performance of liraglutide processed with DehydraTECH. In humans, semaglutide has been shown in other studies to be more than twice as effective at promoting weight loss as liraglutide. Thus, the continued outperformance of DehydraTECH-liraglutide compared to DehydraTECH-semaglutide is of particular interest. In this Study, the liraglutide in Study group H was administered orally even though it is injected when used by patients under the brand names Saxenda® or Victoza®.
Animal Weights (grams)
DehydraTECH Groups | End of Acclimation Period | Day 28 | % Change to Day 28 | Day 56 | % Change to Day 56 |
A: CBD1 | 427.9 | 432.6 | +1.10% | 438.0 | +2.36% |
B: CBD2 | 394.6 | 393.3 | -0.33% | 386.1 | -2.15% |
C: CBD3 | 416.0 | 408.8 | -1.72% | 407.3 | -2.08% |
D: CBD4 | 431.2 | 431.7 | +0.11% | 434.2 | +0.69% |
E: Rybelsus1 w/SNAC | 394.9 | 394.6 | -0.06% | 401.4 | +1.65% |
F: Rybelsus2 w/SNAC | 406.2 | 409.1 | +0.70% | 406.7 | +0.11% |
G: Semaglutide No SNAC | 394.2 | 394.8 | +0.15% | 399 | +1.21% |
H: Liraglutide No SNAC | 392.2 | 385.7 | -1.65% | 373.6 | -4.74% |
Average | 407.1 | 406.3 | -0.21% | 405.8 | -0.37% |
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
For context, in Lexaria's diabetic animal study DIAB-A22-1 reported on March 2, 2023, the obese control group of animals that received no treatment, experienced 3.04% weight gain during the first 28 days of that study.
DehydraTECH-CBD groups B and C are also outperforming all of the Rybelsus® and semaglutide DehydraTECH composition groups regardless of whether the semaglutide has or has not been processed with the salcaprozate sodium technology known as "SNAC". Lexaria is strongly encouraged by the robust performance achieved so far from its DehydraTECH-CBD.
Readers are cautioned to not compare results of this animal study to human weight loss studies, primarily because unlimited food and water has been provided to the animals for the entire duration of this Study. Offered unlimited food, many rats will reach morbid obesity. The primary value in this Study is the relative performance of the different Study groups, which should provide directional evidence for additional future work.
During the initial acclimation phase of 34 days before the beginning of dosing, the animals gained 10.9% body weight on average. Actual weight decreases or slower rates of weight gain have since been achieved in the 8 weeks of dosing in all Study groups receiving DehydraTECH drug therapies.
The Study is ongoing and additional results are expected.
About the Study
Study WEIGHT-A24-1 is underway using diabetic, pre-conditioned Zucker rats. Each arm of the Study is expected to be dosed for a 12-week period following the initial acclimation period. During the Study, over 1,500 blood plasma samples will be 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 arm, statistical significance is not expected and instead, 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. Upon completion of the Study, brain tissue will be analysed to help determine whether DehydraTECH processing results in higher brain absorption than non-DehydraTECH arms, as Lexaria has evidenced numerous times in previous similar animal studies. The Study will also include a comprehensive battery of liver and kidney function testing and blood chemistry analyses. LC-MS/MS and other techniques will be used to analyse samples. All animal groups are offered unlimited access to food throughout the course of the Study.
