DehydraTECH(TM)-enhanced Amycretin and Retatrutide Yield Significant Absorption Improvements in Lexaria's 2026 Animal Study #2
Rhea-AI Summary
Lexaria Bioscience (NASDAQ:LEXX) reported pharmacokinetic results from its 2026 Animal Study #2 in dogs, evaluating DehydraTECH 3.0 (DHT3.0) tablet and capsule formulations of next‑generation GLP‑1 drugs amycretin and retatrutide versus prior DehydraTECH 2.0 (DHT2.0) formulations and intravenous dosing benchmarks.
For amycretin, the best DHT3.0 tablet (ALT 2) achieved an AUC D of 4,967.78 hr*ng/mL/(mg/kg) and absolute bioavailability of 1.65%, a 481.14% increase over the DHT2.0 reference tablet and more than double the 0.70% absolute bioavailability reported in published oral amycretin research without DehydraTECH. All three DHT3.0 amycretin tablets exceeded the DHT2.0 reference tablet, and DHT3.0 with sodium caprate outperformed SNAC-enabled versions.
For retatrutide, all three DHT3.0 tablets and all three DHT3.0 capsules surpassed their respective DHT2.0 SNAC-based references. The top DHT3.0 retatrutide tablet (ALT 2) showed a 4,552.20% absorption improvement versus the reference tablet, while the best DHT3.0 capsules (ALT 1 and ALT 2) in 7 mg format reached 0.26% absolute bioavailability compared to intravenous dosing. Lexaria stated that these findings support its strategic partnering efforts for oral delivery of next‑generation GLP‑1 drugs, while emphasizing that further, including human, studies are required.
Positive
- Amycretin DHT3.0 tablet +481.14% bioavailability vs DHT2.0
- Amycretin absolute bioavailability 1.65% vs 0.70% in published non‑DehydraTECH oral amycretin data
- Retatrutide DHT3.0 tablet +4,552.20% absorption vs DHT2.0 reference
- DHT3.0 retatrutide capsules 0.26% absolute bioavailability at 7 mg dose
- All DHT3.0 amycretin tablets outperformed the DHT2.0 SNAC-based reference tablet
- All DHT3.0 retatrutide tablets and capsules outperformed their DHT2.0 SNAC-based references
Negative
- Retatrutide DHT3.0 oral bioavailability 0.26% remains below published semaglutide dog range of 0.33–0.63%
- Lexaria notes inter-species variability and limited published comparators, indicating results require extensive human studies for validation
News Explained
The update completes dog pharmacokinetic testing but leaves further reporting and human validation unresolved; it changes the evidence base, not ownership.
Lexaria reports that blood-plasma pharmacokinetic testing is complete for its self-sponsored 2026 Animal Study #2, adding dog-study evidence for partnering outreach rather than announcing a financing, license, or ownership change.
The release’s “significant” and “astonishing” framing describes relative absorption versus DHT2.0 reference formulations; Lexaria also says retatrutide reproducibility is unknown and that inter-species differences may affect the amycretin comparison with published primate data.
The completed pharmacokinetic testing is not the end of the disclosed work: tolerability and other study data remain subject to further analysis and reporting, while extensive human studies would be required to validate oral retatrutide.

KELOWNA, BC / ACCESS Newswire / August 24, 2026 / Lexaria Bioscience Corp. (NASDAQ:LEXX) ("Lexaria" or the "Company"), a global innovator in oral drug delivery platforms, announces that blood plasma pharmacokinetic ("PK") bioanalysis testing has been completed in its 2026 Animal Study #2 (GLP-1-A26-2, the "Study"). The Study examined oral delivery of 2 next-generation glucagon-like peptide-1 ("GLP-1") drugs, amycretin and retatrutide, in a total of 18 different study arms in dogs following formulation and processing using Lexaria's patented DehydraTECHTM ("DHT") drug delivery enabling platform technology formulated in oral tablet and capsule formats.
The Study utilized both Lexaria's DehydraTECH-GLP-1 2.0 ("DHT2.0") formulation tested against Lexaria's new DehydraTECH-GLP-1 3.0 ("DHT3.0") formulations together with potentially complementary commercially available gastrointestinal absorption enhancer compounds; salcaprozate sodium ("SNAC") or sodium caprate. Lexaria is testing DHT3.0 formulations in anticipation of supporting existing and future business development initiatives for the next generation of GLP-1 drugs under development around the world.
"Lexaria never stops innovating in our pursuit of the most effective oral drug delivery possible," said Richard Christopher, CEO of Lexaria. "Not only are our latest enhancements producing clear improvements in performance over earlier versions of DehydraTECH, but those improvements demonstrate our rapidly growing understanding of the interactions between DehydraTECH and the next generation of GLP-1 drugs."

All 3 of the DHT3.0-amycretin tablet variations achieved superior absorption than the amycretin reference tablet ("REF DHT2.0 Tablet") that used DHT2.0 and SNAC. Lexaria considers these improvements in DHT3.0 performance to be deeply meaningful relative to our ultimate goal of attracting widespread adoption of DHT technology within the multi-billion-dollar GLP-1 sector and its next-generation drugs. If confirmed with further testing including human studies, DHT3.0 GLP-1 formulations could eventually be of interest to pharmaceutical companies working towards adoption of their own proprietary weight loss drugs.

About the Study and Absolute Bioavailability
The primary goals of this Study were to investigate compatibility of amycretin and retatrutide with Lexaria's DHT-3.0 formulation and processing technology together with certain potentially complementary commercially available gastrointestinal absorption enhancer compounds, centered around PK performance and tolerability. Blood samples were taken at multiple timepoints over a 24-hour post-dosing period to quantify the PK performance of each composition. There were a total of 9 study arms for each of amycretin and retatrutide, including 1 intravenous arm each to provide
Absolute bioavailability is the fraction of an active drug substance that reaches the systemic circulation following non-intravenous administration compared to an intravenous given dose. This figure is noteworthy particularly when compared to available published scientific literature.
As in Animal Study #1 (GLP-1-A26-1) announced on April 15th, this Study also evaluated alternative DHT formulations to those previously explored or commercially available. The present Study included 1 capsule and 1 tablet composition for each of amycretin and retatrutide using sodium caprate which has itself been shown to influence gastrointestinal absorption.
Retatrutide is owned by Eli Lilly and Company®, whereas amycretin is owned by Novo Nordisk®, and are two of the most powerful, next generation GLP-1 peptide drugs under pre-commercial development in the world today, presently in advanced clinical testing only in injectable formats despite increasing consumer interest and demand for oral GLP-1 therapies.
Additional Study information including tolerability and other data will be released in due course upon completion of all relevant analysis and reporting. This was a self-sponsored Lexaria Study that was fully funded from existing corporate resources.
