Positive Partial 12-Week Body Weight Results from Lexaria's GLP-1 Diabetes Animal Study
DehydraTECH-liraglutide and select DehydraTECH-CBD formulations were the top performing weight loss groups
Accelerated rates of weight loss were experienced during the final 4 weeks of the study in all DehydraTECH groups
KELOWNA, BC / ACCESSWIRE / October 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 partial 12-week (final) body weight results from the recently completed animal study WEIGHT-A24-1 (the "Study").
Animal Weights (grams)
DehydraTECH | End of | Day | % | Day | % | Day | % |
A: CBD1 | 427.9 | 432.6 | +1.10% | 438.0 | +2.36% | 432.3 | +1.046% |
B: CBD2 | 394.6 | 393.3 | -0.33% | 386.1 | -2.15% | 374.9 | -4.996% |
C: CBD3 | 416.0 | 408.8 | -1.72% | 407.3 | -2.08% | 402.5 | -3.237% |
D: CBD4 | 431.2 | 431.7 | +0.11% | 434.2 | +0.69% | 419.0 | -2.829% |
E: Rybelsus1 | 394.9 | 394.6 | -0.06% | 401.4 | +1.65% | 393.6 | -0.321% |
F: Rybelsus2 | 406.2 | 409.1 | +0.70% | 406.7 | +0.11% | 403.1 | -0.780% |
G: Semaglutide | 394.2 | 394.8 | +0.15% | 399.0 | +1.21% | 394.1 | -0.017% |
H: Liraglutide | 392.2 | 385.7 | -1.65% | 373.6 | -4.74% | 369.1 | -5.880% |
Average | 407.1 | 406.3 | -0.21% | 405.8 | -0.37% | 398.6 | -2.127% |
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 select DehydraTECH-CBD groups B, C, and D outperformed all three of the Rybelsus® and 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.
This Study is the world's first 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 outperformance of DehydraTECH-liraglutide compared to DehydraTECH-semaglutide is of notable interest. 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®.
Teva Pharmaceuticals (NYSE:TEVA) on June 24, 2024, announced the authorized launch of a generic version of Novo Nordisk's Victoza® as injected liraglutide and noted that Victoza had annual sales of $1.656 billion as of April, 2024.
Lexaria notes that it has already filed patent applications to recognize the unique outperformance of liraglutide once processed with DehydraTECH delivery technology.
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 has provided directional evidence for additional future work. For context, in an older Lexaria diabetic animal study DIAB-A22-1 reported on March 2, 2023 , the obese control group of animals that received no drug treatment , experienced 3.04% weight gain during the first 28 days of that study.
During the initial acclimation phase of 34 days before the beginning of dosing in this Study, the animals gained 10.9% body weight on average. Actual weight decreases or slower rates of weight gain have since been achieved in the 12 weeks of dosing in all Study groups receiving DehydraTECH drug therapies. Importantly, accelerated rates of weight loss were experienced in all DehydraTECH groups during the final 4 weeks of the study.
Additional data from this Study is pending including blood glucose findings from the animals reported herein, as well as 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 are offered unlimited access to food throughout the course of the Study.
