• DehydraTECH-processed tirzepatide from Zepbound® is being tested in an oral dose format

KELOWNA, BC / ACCESSWIRE / November 25, 2024 / Lexaria Bioscience Corp. (Nasdaq:LEXX) (Nasdaq:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms is pleased to announce that dosing has been completed for human pilot study #3 (the "Study") investigating a DehydraTECH-processed version of the dual action glucagon-like peptide-1 ("GLP-1") + glucose-dependent insulinotropic peptide ("GIP") receptor agonist tirzepatide (sold commercially as Zepbound®) in an oral dose format.

The Study has been dosed in nine (9) healthy volunteers. The final seven-day dosing phase, wherein all subjects received the opposite treatment condition from that which they received during the initial dosing phase, was completed on November 16^th. The initial dosing phase of either a seven-day regimen of oral DehydraTECH-processed tirzepatide capsules or a single injected tirzepatide dose was reported upon positively several weeks ago.

No serious adverse events have been observed thus far during both dosing visits, which serves as a point of interest given Lexaria's desire to create an effective oral version of Eli Lilly's™ tirzepatide products, which currently only exist in an injectable form.

The DehydraTECH composition for the Study was compound-formulated using the commercially available Zepbound® injectable formulation as the tirzepatide input material. Tolerability (side effects), blood absorption levels (pharmacokinetics or "PK"), and blood sugar control are being evaluated in the Study.

Tirzepatide is currently approved for use in the United States under the brand names Zepbound® and Mounjaro®, both owned by Eli Lilly™. These two brands combined are expected to generate approximately $15 billion in revenue in 2024. Eli Lilly™ recently announced that tirzepatide evidenced a 94% reduction in risk of progression to type 2 diabetes over a three-year study, and a reduction of 23% of bodyweight, on average, maintained for three years.

In two previous human pilot studies, Lexaria has evidenced that the oral administration of semaglutide (sold by Novo Nordisk® under the brands Rybelsus®, Ozempic®, and Wegovy®) processed with DehydraTECH yielded improvements in absorption rates and a reduction in both blood sugar and in adverse events, as compared to Rybelsus® tablets alone. The two drugs, semaglutide and tirzepatide, are believed to constitute over 90% of all revenue generated in the GLP-1 / GIP sector today.

Through the Study, Lexaria is attempting to evidence meaningful absorption rates of tirzepatide in an oral format, which is not available in the market today since it is currently administered only by injection. The Company expects that data analysis will occur in December with results available in January, 2025.

About the Study

Many design characteristics of the Study, also referred to as Study GLP-1-H24-3, are similar to Lexaria's initial GLP-1 human pilot study #1. The DehydraTECH-tirzepatide test articles were compound formulated using Zepbound®, strictly for research purposes, and dosed to the subjects under fasted conditions. The Study is designed to measure tolerability and side effects, blood levels of tirzepatide, and blood glucose levels. The DehydraTECH-tirzepatide composition was formulated at a strength of 20 mg tirzepatide administered orally daily for seven days. The Zepbound® formulation had a strength of 2.5 mg tirzepatide administered once via injection with the subject monitored over the same seven-day duration applicable with the oral DehydraTECH-tirzepatide condition. Blood samples were taken multiple times during the first 12 hours post dosing on the first day of each treatment phase, with a final blood draw taken 24 hours after dosing; and, a standardized meal was fed to the test subjects at a point in time after dosing. Single blood samples were also taken daily on each of the second through eighth days following commencement of each dosing visit. A total of 9 healthy subjects completed dosing with each test article following a randomized, cross over study design across two study phases.
