Positive Partial 12-Week Blood Sugar Results from Lexaria's GLP-1 Diabetes Animal Study
DehydraTECH-liraglutide and select DehydraTECH-CBD formulations were the top performing blood sugar groups
KELOWNA, BC / ACCESSWIRE / October 24, 2024 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces that it has received partial 12-week (final) blood sugar results from the recently completed animal study WEIGHT-A24-1 (the "Study").
Blood Sugar Levels (mmol/L) | |||||||
DehydraTECH | Day 7 | Day | % | Day 56 | % | Day 84 | % |
A: CBD1 | 27.4 | 26.2 | -4.31% | 26.9 | -1.90% | 27.7 | 1.09% |
B: CBD2 | 28.4 | 29.2 | 2.73% | 26.6 | -6.22% | 27.3 | -3.76% |
C: CBD3 | 26.4 | 24.9 | -5.99% | 27.1 | 2.46% | 27.5 | 3.85% |
D: CBD4 | 24.6 | 27.9 | 13.16% | 26.8 | 8.94% | 27.0 | 9.75% |
E: Rybelsus1 | 26.4 | 25.5 | -3.60% | 26.8 | 1.33% | 26.8 | 1.59% |
w/SNAC | |||||||
F: Rybelsus2 | 24.9 | 26.8 | 7.70% | 26.4 | 5.96% | 27.3 | 9.58% |
w/SNAC | |||||||
G: Semaglutide | 26.3 | 25.9 | -1.52% | 27.8 | 5.54% | 26.9 | 2.13% |
No SNAC | |||||||
H: Liraglutide | 26.4 | 25.8 | -2.08% | 25.2 | -4.56% | 23.3 | -11.54% |
No SNAC | |||||||
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
Lexaria is strongly encouraged that the DehydraTECH-liraglutide and DehydraTECH-CBD groups A and B outperformed all three of the Rybelsus® and pure semaglutide DehydraTECH composition groups regardless of whether the semaglutide had or had not been processed with the salcaprozate sodium technology known as "SNAC". Rybelsus®, which utilizes Novo Nordisk's proprietary SNAC technology, is the world's only orally administered GLP-1 drug brand.
Study data for four additional animal groups (I, J, K, and L), including a positive control group of Rybelsus® that has not been processed with DehydraTECH, will be available soon. Of the eight Study groups reported on today, DehydraTECH-CBD group B and the sole DehydraTECH-liraglutide group H were both successful in reducing blood sugar levels, while the other six groups, including all three of the Rybelsus® and pure semaglutide DehydraTECH composition groups, were not.
This Study is the world's first to evaluate the relative performance of liraglutide processed with DehydraTECH. Thus, the outperformance of DehydraTECH-liraglutide compared to the other groups is of notable interest and was unexpected. In this Study, the processed liraglutide in Study group H was administered orally even though it is injected when used by patients under the brand names Saxenda® or Victoza®.
Usually, injected versions of drugs have greater efficacy than orally administered versions of the same drug because of superior pharmacokinetics ("PK"). Lexaria's DehydraTECH drug delivery technology has historically enhanced the PK of orally administered drugs, opening a potential for viability in commercial markets.
Additional data from this Study is pending, including body weight and blood glucose findings from the second Study cohort that included positive and vehicle (placebo) control arms. Analyses of brain and blood absorption pharmacokinetic results is also underway, although unforeseen delays at the third-party laboratories involved is affecting timing of completion of this work. Lexaria is working with these laboratories to minimize further delays and will report on these data as soon as possible.
About the Study
Study WEIGHT-A24-1 was completed using diabetic, pre-conditioned Zucker rats. Each arm 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 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 were offered unlimited access to food throughout the course of the Study.
