• Absorption improvements appear to continue with DehydraTECH-processed Rybelsus® vs. Rybelsus® tablets even under "fed" conditions

  • DehydraTECH-treated Rybelsus® does absorb through a mouth-melt product format

KELOWNA, BC / August 29, 2024 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces that tolerability and additional pharmacokinetic ("PK") results from human pilot study #2, GLP-1-H24-2, (the "Study") have been received. Lexaria's DehydraTECH-processed Rybelsus® capsules demonstrated superior tolerability in delivering the GLP-1 drug semaglutide versus commercially available Rybelsus®.

We were pleased to find that none (0) of the 9 people taking the DehydraTECH-processed Rybelsus® swallowed as a capsule experienced any adverse events whatsoever. However, of the 9 human volunteers in the Study taking the Rybelsus® tablet, 6 of them experienced mild adverse events. Five of those same 6 people experienced mild adverse events from taking the dissolvable oral mouth-melt format of DehydraTECH-processed Rybelsus®.

These tolerability findings nicely build upon the those from Lexaria's previous human pilot study #1, GLP-1-H24-1, which also showed the DehydraTECH-processed Rybelsus® capsules to be generally better tolerated than the Rybelsus® tablets that demonstrated instances of moderate nausea or diarrhea.

Combined with the 7 people involved in Lexaria's first human pilot study examining DehydraTECH processing of semaglutide capsules, a total of 16 people have now been dosed with comparable DehydraTECH-processed semaglutide capsules and Rybelsus® tablets. Of those 16 people, 13 or 81%, experienced mild or moderate side effects with the Rybelsus® tablet and only 7 people, or 44%, experienced only mild side effects with the Rybelsus® that was processed with DehydraTECH and administered via capsules. Most of the side effects experienced in all cases were of a gastrointestinal nature including belching, diarrhea and nausea that are commonly associated with GLP-1 drugs, although intensity was lower in all instances with the DehydraTECH-processed Rybelsus® capsules in pilot study #1 or absent altogether in the present Study.

The continuing evidence of decreased adverse events with the DehydraTECH-processed Rybelsus® capsules compared to commercially available Rybelsus® tablets is encouraging. Other reports have noted that Rybelsus® generally produces slightly higher incidences of several common side effects as compared to the injectable product Ozempic®, which outsells Rybelsus® by a factor of almost five-fold. DehydraTECH's ability to improve oral tolerability could, in future, however, help to drive increased use of oral GLP-1 product formats, if proven definitively through thorough registered clinical testing.

Lexaria also reports that the third arm of the Study that evaluated a DehydraTECH-processed Rybelsus® formulation as an in-mouth dissolvable tablet also showed some promise from a conceptual perspective. Across the 18 blood draws from the 20-minute mark until the 24-hour mark in the Study, the average blood concentration level (nmol/) of the Rybelsus® tablet was 3.93; for the DehydraTECH-processed Rybelsus® mouth-melt it was 1.27 or 32.3% of the Rybelsus® tablet results; and for the DehydraTECH-processed Rybelsus® it was 4.20 or 106.9% of the Rybelsus® tablet results.

The Company is unaware whether the in-mouth dissolvable tablet product format has ever been used before to attempt to deliver a GLP-1 drug. As such, there was a real possibility that it would fail to do so. Instead, it delivered roughly one-quarter to one-third of the quantity of drug into blood as the Rybelsus® tablet. If this absorption is additive to the existing gastrointestinal absorption, this could be a very interesting incrementally positive result.

This was the first Study designed to investigate whether DehydraTECH-enhanced semaglutide can absorb at any level systemically through the sublingual/buccal tissues of the mouth and throat with some effective drug delivery into the bloodstream.

As this published study notes, the level of expected weight loss associated with GLP-1 drugs is directly correlated with the quantity of GLP-1 drug circulating in the blood stream. It is for this reason that Lexaria is constantly pursuing any and all improvements in drug delivery that are possible.

About the Study
Design characteristics of the Study are comparable to Lexaria's initial human pilot study. The DehydraTECH-semaglutide test articles were compound formulated using crushed Rybelsus®tablets strictly for research purposes. The Study is designed to measure tolerability and side effects, blood levels of semaglutide, blood glucose and insulin levels. Blood samples were taken multiple times during the first 10 hours post dosing; a final blood draw was taken 24 hours after dosing; and a standardized meal was allowed pre-dosing and fed to the test subjects at a point in time after dosing. Nine healthy subjects were dosed in each of the first two study arms, and seven were dosed in the final study arm.

About Semaglutide
Rybelsus® (semaglutide) is the only GLP-1 drug approved by the FDA for oral dosing to treat diabetes and weight loss. The FDA has also approved semaglutide marketed as Ozempic® and Wegovy®, administered by injection, to treat diabetes and weight loss. All three of these drugs are owned and manufactured by Novo Nordisk®.

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.

Trend toward higher overall absorption under fed conditions evidenced with DehydraTECH®-processed Rybelsus®

KELOWNA, BC / August 27, 2024 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces that the first results from human pilot study #2, GLP-1-H24-2 (the "Study"), have been received. Lexaria's DehydraTECH®-processed Rybelsus® evidenced a trend toward higher overall absorption compared to Rybelsus® that was not processed with DehydraTECH.

Since Lexaria has already demonstrated superior pharmacokinetic performance of its DehydraTECH-processed Rybelsus® under the recommended dosing conditions on an empty stomach in previously announced human pilot study #1, GLP-1-H24-1, it was deemed to be of scientific interest to learn whether the DehydraTECH advantages were also experienced under fed conditions. The DehydraTECH-processed Rybelsus® evidenced higher semaglutide levels in 17 of the 19 blood draws taken until the 24-hour completion of the study averaging 18.8% higher semaglutide levels over the course of the study compared to Rybelsus® alone, although the differences were variable and not significant statistically with such a small sample size.

The two arms of the Study being reported today compared equal 7 mg semaglutide doses from a Rybelsus® swallowed tablet versus a DehydraTECH-processed Rybelsus® swallowed capsule. The volunteers in this Study were administered the drugs while they were in a "fed" state, as compared to an earlier study that demonstrated a 43% peak blood level improvement wherein the volunteers were administered the drug in a "fasted" state. It should be noted that Novo Nordisk™, the owner and manufacturer of Rybelsus®, recommends taking Rybelsus® on an empty stomach, because studies have shown that Rybelsus administration under fed conditions leads to decreased systemic absorption. Their label reads, "Take RYBELSUS® by mouth on an empty stomach when you first wake up with a sip of plain water (no more than 4 ounces)."

"Lexaria is delighted that our contracted clinical research organization was able to complete the active phase of the Study on schedule," said Chris Bunka, Chief Executive Officer of the Company. "The results of these Study arms have shown that DehydraTECH appears to continue to offer pharmacokinetic improvements even when dosed under fed conditions, reinforcing DehydraTECH's beneficial delivery kinetics."

Next steps moving forward in Lexaria's 2024 GLP-1 experimental program will include finalization of our ongoing animal study, which has already produced positive results as previously announced, and continued progress toward initiation of our planned upcoming 12-week chronic human study, which will be conducted under fasted dosing conditions. Data from the tolerability evaluations and the mouth melt absorption Study arm will also be available soon.

  • DehydraTECH-liraglutide is outperforming DehydraTECH-semaglutide

  • Select DehydraTECH-CBD formulations appear to continue to outperform DehydraTECH-semaglutide

KELOWNA, BC / 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®.

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.

  • DehydraTECH-liraglutide is showing apparent superiority to DehydraTECH-semaglutide

  • Select DehydraTECH-CBD formulations are showing apparent superiority to DehydraTECH-GLP-1 at 4 and 8 weeks

KELOWNA, BC / August 21, 2024 / Lexaria Bioscience Corp. (NASDAQ:LEXX) & (NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces that it has received 4-week and 8-week blood glucose results from ongoing animal study WEIGHT-A24-1 (the "Study").

DehydraTECH-liraglutide (Group H) and two DehydraTECH-CBD formulations (Groups A & B) were the top performers in the Study at day 56, with blood sugar level reductions of 2.50%, 1.90% and 1.53% respectively. This appears to support Lexaria's belief that DehydraTECH-CBD may have utility, especially if used together with a GLP-1 drug, in diabetic control. Animal testing of combination DehydraTECH-CBD with DehydraTECH-GLP-1 drugs is ongoing and in the final phases of the Study.

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 16.7% blood sugar concentration increases, relative to baseline by day 56 of that study. In the current Study, each of the 8 active groups of animals either experienced a smaller increase, or an actual decrease in blood sugar level relative to baseline as compared to the obese control group in the previous study. Interestingly, none of the animals receiving semaglutide experienced actual decreases by day 56 although some decreases were observed at day 28.

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

The continued relative outperformance of DehydraTECH liraglutide is extremely interesting, in part because of Lexaria's proprietary DehydraTECH technology and its applicability to GLP-1 molecules. In other human studies, semaglutide tends to outperform liraglutide in blood sugar control, when not processed with DehydraTECH.

Liraglutide is currently available commercially by Novo Nordisk® sold under the brand names Victoza® and Saxenda®, but the related patents have begun to expire and open the door to new competitors. For example, Teva Pharmaceutical Industries Ltd® recently launched the first generic injectable version of this GLP-1 drug. Although liraglutide was administered as an oral DehydraTECH-enabled dose in this Study, it is currently only sold and prescribed as a subcutaneous injection (see below for more context).

The Study is ongoing and additional results are expected soon.

About Liraglutide
Liraglutide is owned by Novo Nordisk® and sold under the Victoza® and Saxena® brands which generated $1.6 billion in combined revenue in 2022. Liraglutide is currently administered only by injection, after attempts to utilize the sodium salcaprozate ("SNAC") technology found in semaglutide (and sold as the oral tablet Rybelsus®) failed to deliver sufficient performance to enable an oral form factor.

Previous investigators reported that "the absorption enhancing action of SNAC is thought to be highly dependent on the specific agent it is enhancing, which means that carefully tailored co-formulation is required rather than co-administration. The structure of liraglutide (a structurally distinct analog of GLP-1RA) was found to be unfavorable for co-formulation with SNAC on account of its stronger membrane-binding properties, which reduced transcellular passage, as well as its greater tendency to oligomerize, which countered the monomerizing effects of SNAC. In a preclinical study, plasma exposure was significantly higher for semaglutide than liraglutide after oral dosing with SNAC."

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 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 Study.

Monomeric form of GLP-1 drug preserved by DehydraTECH

KELOWNA, BC / August 19, 2024 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces positive findings from its applied research program together with the National Research Council of Canada ("NRC") that evaluated important mode of action facets of DehydraTECH processed with the glucagon-peptide 1 ("GLP-1") drug, semaglutide.

This highly technical work program examined the molecular properties of DehydraTECH-processed pure semaglutide in comparison to the commercially available semaglutide formulation Rybelsus® using simulated gastric fluid and thereby mimicking conditions in the human gut. A battery of testing methods were employed, including polyacrylamide gel electrophoresis ("PAGE"), size exclusion chromatography ("SEC"), electrospray ionization mass spectrometry ("ESI-LCMS") and dynamic light scattering ("DLS").

Findings from the PAGE and SEC analyses in particular clearly showed not only that semaglutide was efficiently released in the simulated gastric fluid environment with each of two formulations tested, but also that the semaglutide in both formulations was likely in monomeric form. This result is compelling because the available published literature describing Rybelsus® notes that it occurs in simple monomeric form in the human gut due to its proprietary salcaprozate sodium ("SNAC") ingredient chemistry.

This property is important because it allows for permeation of the gastric epithelium for delivery systemically by resisting a tendency to otherwise complex in the gut into larger oligomeric form. Therefore, it is encouraging that Lexaria's DehydraTECH technology also appears to achieve the desired monomeric form without the presence of SNAC.

Novo Nordisk® paid a total of ~US$1.8 billion in 2020 to acquire the SNAC technology that is now utilized within Rybelsus® tablets.

Findings from the DLS and ESI-LCMSS testing were less conclusive experimentally, although the latter also appeared to show monomerization of the semaglutide samples similar to the PAGE and SEC analyses.

These findings help to build upon Lexaria's growing dataset around DehydraTECH amenability to GLP-1 formulation and oral delivery performance. Further experimentation is under consideration with Lexaria's partners at the NRC to expand upon this work, possibly including experimentation under additional parameters mimicking human gut conditions.
