• Clinical study will evaluate safety and tolerability of Lexaria's patented DehydraTECH-CBD as a potential treatment for hypertension
• California-based InClin to provide CRO services to manage and expedite the study
• Lexaria is working with its regulatory and clinical advisors toward upcoming IND submission

KELOWNA, BC / ACCESSWIRE / April 24, 2023 / Lexaria Bioscience Corp. (Nasdaq:LEXX) (Nasdaq:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces it has awarded the contract for clinical research organization ("CRO") services for its expected upcoming Food and Drug Administration ("FDA")-registered, U.S. Phase 1b Investigational New Drug ("IND") hypertension study HYPER-H23-1 with its patented DehydraTECH-powered cannabidiol ("DehydraTECH-CBD") to California-based InClin, Inc.

Study HYPER-H23-1 is entitled 'A Phase 1b Randomized, Double-Blind, Placebo-Controlled Study of the Safety, Pharmacokinetics, and Pharmacodynamics of DehydraTECH-CBD in Subjects with Stage 1 or Stage 2 Hypertension' . The primary objective of the study will be to evaluate safety and tolerability in 120 hypertensive patients, and secondary objectives will include efficacy evaluation in reducing blood pressure together with detailed pharmacokinetic testing.

InClin is about to begin study start-up and preparatory activities to enable Lexaria to "hit the ground running" with patient dosing as soon as possible after the expected FDA IND filing and review is completed. Lexaria anticipates filing the IND this summer with hoped-for FDA authorization within about 60 days, resulting in the Phase 1(b) trial aggressively targeting commencement of patient dosing as early as October 2023.

The study start-up services to be provided by InClin include but are not limited to: clinical site evaluation and selection, personnel and site training, project management, clinical database design and management, quality assurance support, medical writing, study documentation creation, biostatistics and programming, support vendor coordination, Independent Review Board ("IRB") submissions and more.

Lexaria had a successful outcome following its FDA pre-IND meeting as announced on August 10, 2022. Since then, the Company has been working tirelessly with its regulatory and clinical advisors on refining the study plan and preparing for the IND submission pursuant to the pre-IND guidance it received from the FDA. The Company is in the process of performing the drug product manufacturing and stability testing required as part of the upcoming IND submission, compliant with current Good Manufacturing Practice ("cGMP") regulations. Assembling the stability data from its cGMP-manufactured batch production work is one of the last requirements prior to Lexaria submitting its formal IND application to the FDA this summer.

Lexaria's five previous human clinical studies conducted from 2018 through 2022, which were not conducted under FDA-registration but are expected to be integral to successful filing and review of its upcoming IND submission, were carried out in an aggregate total of 134 healthy and hypertensive persons. These foundational studies evidenced significant reductions in resting blood pressure over both acute and multi-week dosing regimens, and also produced zero serious adverse events; suggesting that DehydraTECH-CBD has the potential to have pronounced clinical benefits relative to available anti-hypertensive therapeutics.

Lexaria is aware of only a handful of other published research studies, mostly in young, healthy and normotensive volunteers, that have investigated whether a sustained decrease in resting blood pressure is possible following multiple weeks of oral CBD dosing; none of which have been successful in achieving this. DehydraTECH-CBD is currently unique in its evidenced superior power to reduce blood pressure over other oral CBD formulations.

Findings from Lexaria's latest study HYPER-H21-4 demonstrated a potentially novel mechanism of action of DehydraTECH-CBD in reducing blood pressure which may be explained, at least in part, by its interaction with the human sympatho-chromaffin system via catestatin modulation as detailed in the peer-reviewed and published respected journal, " Biomedicine and Pharmacotherapy ". This is of significance because the FDA has previously laid out clear guidelines for sponsors who seek to develop new anti-hypertensive drugs, specifically defining the need for medications that offer novel and complementary modes of action. Data gathered from study HYPER-H21-4 suggested that DehydraTECH-CBD had the potential to offer additive blood pressure reduction benefits on top of any degree of improvements that standard of care medications achieved for patients prior to DehydraTECH-CBD dosing.

About DehydraTECH-CBD

DehydraTECH-CBD is a unique CBD formulation Lexaria has developed and is optimizing based on its patented and proprietary DehydraTECH drug delivery technology. DehydraTECH is designed to improve the way active molecules enter the bloodstream upon oral ingestion. DehydraTECH has also demonstrated enhanced delivery of certain active molecules including CBD into brain tissue, which Lexaria believes to be of particular importance for the effectiveness of its DehydraTECH-CBD specifically against hypertension because of the significant influence of central mediation upon blood pressure. Lexaria has also developed DehydraTECH-CBD formulations for other applications demonstrating superior bio-absorption when administered intraorally and topically.
