Lexaria Bioscience Corp. (NASDAQ:LEXX) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, announces that dosing began on schedule on June 14th with Human Pilot Study #7 (GLP-1-H26-7) that is evaluating two oral DehydraTECH-semaglutide ("DHT-sema") compositions against Novo Nordisk's® ("Novo") commercially available Wegovy® tablets, over a 5-week duration (the "Study").

Lexaria is seeking to preserve the superior safety and tolerability profiles evidenced in its previous glucagon-like peptide-1 ("GLP-1") studies such as Human Study #4 (GLP-1-H24-4), combined with pharmacokinetic ("PK") performance that matches or exceeds the Wegovy® tablet control. Previous Lexaria salcaprozate sodium ("SNAC")-inclusive DHT-sema single dose studies such as Human Pilot Studies #1 and #2 (GLP-1-H24-1 and GLP-1-H24-2) evidenced PK performance that matched or exceeded the Rybelsus® control arm and also evidenced noteworthy safety and tolerability profiles.

The results of this Study are expected to be carefully reviewed by the pharmaceutical industry in order to evaluate the possibility of entering into commercial relationships focused on Lexaria's proprietary DehydraTECH™ technology.

The Study is investigating three separate arms to assess safety & tolerability as well as PK properties that will compare SNAC-inclusive, DHT-sema compositions formulated in both tablet and capsule formats to commercially available Wegovy® tablets. The Study is being conducted under fasted pre-dose conditions similar to the advised administration criteria of Novo's oral semaglutide products. The 5-week dosing duration was selected in order to allow for achievement of steady state concentration levels, meaning that the semaglutide blood quantities in each arm will be expected to reach an equilibrium level that balances drug input with natural bodily elimination.

The Study is exploring several new DehydraTECH™ enhancements not previously evaluated, which include but are not limited to the following two main improvements:

(1) First, an oral tablet DHT-sema composition will be used by Lexaria for the first time, as opposed to only the capsule compositions administered in all our previous DehydraTECH™ GLP-1 studies. Novo's Rybelsus® and Wegovy® oral semaglutide medications use specially formulated tablets designed to temporarily adhere to the stomach lining and disintegrate and dissolve releasing agents in a focal manner that aids in optimizing absorption of semaglutide into the human body. For the first time ever, Lexaria has attempted to mimic and integrate certain physical properties of the Rybelsus® and Wegovy® SNAC-inclusive tablet delivery modality into its DHT-sema tablets to follow established industry standards and thereby increase the likelihood of subsequent commercial pharmaceutical relationships.

(2) Second, both the Lexaria DHT-sema tablet and capsule test articles will be formulated with SNAC, which will be the first time these formulations will be evaluated over a multi-dose, multi-week time period in humans. The five-week dosing duration of the Study is expected to be long enough to reach so-called steady-state, which is when drug concentrations in the body reach a constant concentration. As noted above, Human Pilot Studies #1 and #2 (GLP-1-H24-1 and GLP-1-H24-2), conducted in 2024 and 2025 which incorporated SNAC (but did not use tablets), were limited by single-dose study designs and therefore of much shorter duration.

The Study is fully funded from existing corporate resources.
