KELOWNA, BC / November 10, 2021 / Lexaria Bioscience Corp. (Nasdaq:LEXX)(Nasdaq:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, announces its plans for several new and ongoing DehydraTECH^TM applied R&D programs for 2022. The studies mentioned herein are only a fraction of Lexaria's 2022 work programs.

"Calendar 2022 will continue to see significant milestones in utilizing DehydraTECH-CBD for investigation of heart disease and hypertension; and separately, for oral nicotine delivery as an alternative to smoking", said Chris Bunka, CEO of Lexaria Bioscience Corp. "We are delighted to announce that DehydraTECH as an enhanced drug delivery platform will also be evaluated for characteristics and potential treatment options for hormone replacement, dementia, rheumatoid disease and diabetes."

Heart disease is the #1 killer in the US, responsible for the deaths of 659,000 Americans each year; and cigarette smoking is the #3 killer in the US, responsible for the deaths of 480,000 Americans per year. Lexaria continues its unwavering commitment to lessening the loss of life in these areas and will detail these advanced work programs in the heart disease and nicotine sectors in separate communications.

During 2022, Lexaria will also be conducting pharmacokinetic ("PK") and efficacy modelling studies in animals to evaluate DehydraTECH's ability to improve the delivery characteristics of many other drugs or active pharmaceutical ingredients ("APIs") and determine whether there might be commercial benefit to continue with further pursuit within different market sectors. The following studies are part of approximately 12 applied R&D programs planned for 2022 (tentative start dates are included):

HOR-A22-1: April, 2022. This PK study will evaluate the ability of DehydraTECH to enhance the delivery characteristics of estrogen. Estrogen helps to control the menstrual cycle but also controls cholesterol and protects bone health. The hormone replacement market is estimated at $46.5 billion in 2027.

DEM-A22-1: July, 2022. This efficacy study will evaluate DehydraTECH-CBD with and without nicotine for the potential treatment of dementia. Alzheimer's disease is the most common form of dementia and accounts for at least 60% of all cases, and nicotine is already showing promising results related to Alzheimer's treatment. An estimated 55 million people worldwide are currently affected by dementia, with 78 million expected to be living with some form of dementia by 2030. The dementia drug treatment market is estimated at $19.6 billion in 2026.

RHEUM-A22-1: October, 2022. This efficacy study will focus on the ability of DehydraTECH-CBD to potentially affect treatment of rheumatoid disease. Given CBD's postulated efficacy related to inflammation, Lexaria will explore a possible role for CBD in this area of investigation. Rheumatic diseases are autoimmune and inflammatory diseases that cause the immune system to attack joints, bones, muscles and organs. There are over 100 rheumatic diseases including Fibromyalgia, Lupus, Osteoarthritis, Rheumatoid Arthritis and more. The Rheumatoid Arthritis therapeutics market alone is expected to be over $30 billion per year by 2025.

DIAB-A22-1: November, 2022. This efficacy study will explore the ability of DehydraTECH-CBD to potentially affect treatment of diabetes. Diabetes prevents the body from making enough insulin, resulting in abnormal blood sugar levels. Diabetes is the 7^th largest cause of death in the US and there is currently no cure. Investigation of CBD related to diabetes is in early stages, though there are some areas of ongoing investigation. CBD has shown some ability to reduce the incidence of diabetes in mice. The prescription drug market used to treat diabetes is expected to be a $77.9 billion global market in 2024.

Lexaria raised approximately USD$15 million in funding during 2021 which has enabled the active work programs of 2021 and supported significant advances in the fields of heart disease, oral nicotine, and antiviral research. Lexaria's budget for applied R&D during 2022 is fully funded and includes each of the R&D programs noted within this press release. Lexaria's objective for its R&D programs is to build significant value for all Lexaria stakeholders while pursuing policies for significant improvements to human health.

Lexaria is debt free and expects its current cash reserves to meet all its needs until at least Q2, 2023. Lexaria plans to seek strategic corporate business partners for many of its specific drug investigations after sufficient data has been generated which, if successful, could generate any combination of up-front, milestone, and/or royalty payments to Lexaria.

In other news, Lexaria has engaged Barretto Pacific Corporation to provide various investor relations related services for compensation of USD$56,000 for the first four months, and USD$12,000 per month thereafter for the remainder of the 1-year term. Lexaria has also retained the consulting services of Mei Kuo for a 3-month period ending January 08, 2022, for public relations, marketing and similar related services in return for payment of USD$15,000 per month. No stock or options have or will be issued in relation to either contract.

• DehydraTECH-CBD also being evaluated in three other human clinical studies
• Positive studies would support Lexaria's regulatory approval plans

KELOWNA, BC / November 3, 2021 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, announces a significant new study to expand its hypertension clinical program and provides updates on three ongoing human clinical studies evaluating its proprietary DehydraTECH-CBD for potentially treating hypertension and heart disease.

"HYPER-H21-4 is the most ambitious study Lexaria has ever undertaken and is enabled from the successful outcomes from our other 2021 human hypertension studies," said Chris Bunka, CEO of Lexaria Bioscience Corp. "Outcomes from this study could support Lexaria's goals related to pursuit of regulatory approvals for DehydraTECH-CBD for potential use as a treatment for high blood pressure."

HYPER-H21-4

HYPER-H21-4 is expected to consist of 60 volunteers between the ages of 45-70 using three 150 mg doses of DehydraTECH-CBD, every day for the 6-week duration of the study. The study will use a double blinded, randomized cross-over design, and utilize a placebo control. Some volunteers will already be using leading standard of care hypertension drugs such as ACE inhibitors with or without diuretics to help evaluate the efficacy of DehydraTECH CBD with and without other hypertension treatments. The extended duration of the study will allow Lexaria to gather critical data monitoring extended use of DehydraTECH-CBD and will evaluate the potential for longer term health benefits. Study protocols are being readied for submission to the Independent Review Board ("IRB") and approval is anticipated by January, 2022.

HYPER-H21-4 is more comprehensive than any work previously undertaken by Lexaria and many types of analysis will be performed including 24-hour ambulatory blood pressure (which is the primary outcome); arterial stiffness and autonomic balance; brain structure and function through brain magnetic resonance imaging ("MRI"); blood biomarkers (including lipids such as cholesterol and more); renal, hepatic, sleep quality / daytime sleepiness / sleep disorders; actigraphy, geriatric depression scale, perceived stress, and Beck anxiety inventory. The wide range of data collection could provide additional insights into the benefits of DehydraTECH-CBD that might otherwise remain hidden from view.

HYPER-H21-4 is expected to produce an enormous amount of data that, if positive, should be supportive of Lexaria's plans to enter regulatory pathways anticipated to result in eventual regulatory approval to use DehydraTECH-CBD to treat hypertension and perhaps other forms of cardiovascular disease. This study is entirely funded through the Company's existing cash resources and is not subject to any financing requirement.

Updates on Other Hypertension Studies

HYPER-H21-1

Partial results, related only to BP readings, were released on July 29, 2021, as summarized below. This study was conducted in 24 adult volunteers, used a single dose of 300 mg of DehydraTECH-CBD, and measured results over a number of hours. Pending analyses and results include speed and rate of absorption of the CBD and its main metabolites, as well as evaluation of inflammatory markers associated with cardiovascular disease and gold-standard biomarkers of nitric oxide. This latter measure is expected to provide mechanistic insight into the witnessed reduction in blood pressure via vasodilation. Those results were originally expected to be released by October, but are now due by early December due to certain supply chain challenges.

BP reduction from baseline was greatest when measured via systolic pressure. In the subset of volunteers who were Stage 2 hypertensive, peak systolic BP reductions from baseline were observed of as much as approximately 13 mmHg by the 50-minute time point with DehydraTECH-CBD, and systolic BP remained depressed throughout almost the entire 3-hour duration of the study. For reference, other studies of coronary heart disease ("CHD") have concluded that "lowering systolic pressure by 10 mm Hg or diastolic pressure by 5 mm Hg using any of the main classes of drugs reduced CHD events (fatal and nonfatal) by about a quarter and stroke by about a third, regardless of the presence or absence of vascular disease and of pretreatment BP. Heart failure is also reduced by about 25%."

HYPER-H21-2

Partial results were released on September 7, 2021 as summarized below. This study was conducted in 16 adult volunteers, used three doses of 150 mg each of DehydraTECH-CBD, and measured results over a 24-hour ambulatory time-period. Pending analyses and results to be concluded include additional blood pressure subset analyses, sleep quality and other data analyses that are in progress and final results are expected in early December.

At selected times during the 24-hour study, volunteers with mild to moderate hypertension averaged as much as a 20 mmHg (i.e., 23%) decrease in BP relative to placebo. Over the 24-hour ambulatory monitoring period, volunteers averaged a significant reduction of 7.0% (p < 0.001) in systolic pressure with DehydraTECH-CBD relative to placebo.

HYPER-H21-3

DehydraTECH-CBD manufacturing for this study is complete and the clinical test articles have been delivered to the study location where dosing is expected to begin in mid-November or thereabouts, and dosing is expected to be complete by mid-December. Thereafter, the BP findings are expected to be reportable by the end of January, 2022.

HYPER-H21-3 will be conducted in 16 adult volunteers and will utilize a single dose of 300mg of DehydraTECH-CBD. This study is designed to evaluate acute pulmonary hypertension and cardiovascular effects under severe stress. Exposure to acute reductions in oxygen tension (i.e., hypoxia) causes rapid hypoxic pulmonary vasoconstriction ("HPV") and, as a consequence of this HPV response, pulmonary arterial pressure increases. If this increase in pressure becomes too high, as is the case in many cardiac pathologies, an excess of fluid in the lungs can occur that causes difficulty with breathing. The extent to which DehydraTECH-CBD may act as a novel treatment for HPV, and potentially as an alternative treatment for pulmonary hypertension, is unknown. Thus, the primary objective of this study is to evaluate the effect of DehydraTECH-CBD on pulmonary vascular function in normotensive individuals exposed to hypoxia. The magnitude of HPV, blood pressure, heart rate, blood samples, and pulmonary gas exchange data will be collected and analyzed.

Hypertension and Cardiovascular Disease Markets

About 1.28 billion people worldwide suffer from hypertension - elevated blood pressure-in a market valued at $28 billion per year and is recognized as one of the world's top health problems. Only 21% of people with hypertension have it under control which demonstrates enormous unmet need. Hypertension is one subset of the broader cardiovascular disease category, which is expected to be a $146 billion market in 2022.

"Among persons 50 years of age or older, isolated systolic hypertension is the most common form of hypertension, and systolic blood pressure becomes more important than diastolic blood pressure as an independent risk predictor for coronary events, stroke, heart failure, and end-stage renal disease ("ESRD"). The Global Burden of Disease Study identified elevated blood pressure as the leading risk factor, among 67 studied, for death and disability-adjusted life-years lost during 2010."

Drugs focused on blood pressure and related conditions are some of the best selling drugs in the world. Lipitor, used to treat high cholesterol and reduce the risk of heart disease, has generated $94.7 billion in revenue from 1992 until 2017. Plavix is used to prevent heart attack and stroke, has sold $46.5 billion from 1992 until 2017. There are several hypertension drugs that each generate $1 billion per year or more in revenue.

• New study EPIL-A21-1 will compare effectiveness of FDA-approved Epidiolex to DehydraTECH^TM-CBD for reducing seizure activity

KELOWNA, BC / November 1, 2021 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, has commenced an important new study exploring whether DehydraTECH^TM-CBD evidences superior ability to inhibit seizure activity compared to both generic cannabidiol ("CBD") and Epidiolex.

Epidiolex is the first and only FDA-approved CBD medication for the treatment of seizures associated with two rare and severe forms of paediatric epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.

Experts in respirology and neurobiology are among the talented team assembled to conduct the study which is designed to investigate if DehydraTECH-CBD has similar or superior levels of efficacy in treating seizures as does the world's only CBD-based seizure medication, Epidiolex. Lexaria's seizure program has been developed due to the significant gains in systemic delivery and brain uptake that Lexaria has repeatedly evidenced and announced from other studies comparing DehydraTECH-CBD with concentration-matched controls, which it believes has potential to improve therapeutic efficacy for a range of disease conditions affecting the central nervous system including epilepsy.

Epidiolex was developed by GW Pharmaceuticals plc ("GW") and is now sold by Jazz Pharmaceuticals ("Jazz") subsequent to the 2021 US$7.2 billion takeover of GW by Jazz.

Animal study EPIL-A21-1 has entered early-stage preparatory work and results are expected by Q3 2022. This animal study is being conducted by a leading US-based independent laboratory using advanced DehydraTECH 2.0 formulations and is fully funded through existing Lexaria resources.

In other developments, Lexaria is pleased to report its first patent award for DehydraTECH in Mexico. The patent award protects Lexaria's proprietary DehydraTECH for use with cannabinoids and nicotine. The Company has also been awarded another patent in Japan for the use of DehydraTECH utilizing non-psychoactive cannabinoids, nicotine, vitamins, or non-steroidal anti-inflammatory ("NSAID") substances. This latest patent award in Japan becomes Lexaria's 5th patent awarded in 2021. Lexaria's patented DehydraTECH currently benefits from 23 granted patents in the countries of the USA, Australia, the European Union, India, Japan, and Mexico. Lexaria continues to build its intellectual property portfolio in these and other countries.

About Epidiolex

Epidiolex is an FDA-approved prescription CBD available in an oral solution to treat Lennox-Gastaut syndrome and Dravet syndrome in children two years of age and older. Epidiolex's effectiveness was studied in three randomized clinical trials involving a total of 516 patients and was shown to be effective in reducing the frequency of seizures when compared to placebo. In September 2019, Epidiolex was approved for use in all 27 member countries of the European Union.
