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

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

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.

ABBVIE'S ALLEGED MISCONDUCT

AbbVie is one of the world's largest pharmaceutical companies. The company's revenues will come under significant pressure in the coming years when its best-selling drug, Humira, will lose patent protection in 2023. Accordingly, AbbVie's future revenue and earnings depend in large part on its ability to develop new sources of revenue to offset Humira's lost sales. Rinvoq-an anti-inflammatory drug manufactured by AbbVie and used to treat rheumatoid arthritis (RA) and other diseases by inhibiting Janus kinase (JAK) enzymes-was touted as one such drug. Rinvoq was initially approved in the United States to treat only moderate to severe RA. However, AbbVie was actively pursuing additional treatment indications and, in 2020, asked the U.S. Food and Drug Administration (FDA) to approve Rinvoq for the treatment of several other diseases.

As is relevant here, Rinvoq is similar to other JAK inhibitor drugs, including Xeljanz, manufactured by Pfizer Inc. When the FDA approved Xeljanz in 2012 for the treatment of RA, it required an additional safety trial to evaluate Xeljanz's risk of triggering certain serious side effects. Beginning in February 2019, the FDA repeatedly warned the public that the safety trial indicated that Xeljanz's use could lead to serious heart-related issue, cancer, and other adverse events. Notwithstanding the similarities between Rinvoq and Xeljanz, during the Class Period, Defendants assured investors that Rinvoq was far safer than Xeljanz and not subject to the same regulatory risks.

However, investors began to learn the truth about Rinvoq's significant risks on June 25, 2021, when AbbVie revealed that the FDA was delaying its review of expanded treatment applications for Rinvoq due to the safety concerns associated with Xeljanz. On this news, the price of AbbVie common stock declined $1.76 per share, or approximately 1.5%, from a close of $114.74 per share on June 24, 2021, to close at $112.98 per share on June 25, 2021.

Then, on September 1, 2021, the FDA announced that final results from the Xeljanz safety trial established an increased risk of serious adverse events, even with low doses of Xeljanz. As a result, the FDA determined that it would require new and updated warnings for Xeljanz and Rinvoq because Rinvoq "share[s] similar mechanisms of action with Xeljanz" and "may have similar risks as seen in the Xeljanz safety trial." The FDA also indicated that it would further limit approved indications for Rinvoq as a result of these safety concerns. On this news, the price of AbbVie common stock declined $8.51 per share, or more than 7%, from a close of $120.78 per share on August 31, 2021, to close at $112.27 per share on September 1, 2021.

After the Class Period, on December 3, 2021, AbbVie announced that the FDA had updated Rinvoq's label to require additional safety warnings and limit marketing of Rinvoq to only its use after treatment with other drugs has failed. On January 11, 2022, Defendants admitted that these changes to Rinvoq's label would negatively impact sales, forcing the Company to reduce its long-term guidance for Rinvoq's sales in 2025.

The complaint alleges that, throughout the Class Period, the Defendants made materially false and/or misleading statements, about the company's business and operations. Specifically, Defendants misrepresented and/or failed to disclose that: (1) safety concerns about Xeljanz extended to Rinvoq and other JAK inhibitors; (2) as a result, it was likely that the FDA would require additional safety warnings for Rinvoq and would delay the approval of additional treatment indications for Rinvoq; and (3) therefore, Defendants' statements about the company's business, operations, and prospects lacked a reasonable basis, As a result of the Defendants' wrongful acts and omissions, and the significant decline in the market value of AbbVie's securities, AbbVie investors have suffered significant damages.

WHAT CAN I DO?

AbbVieinvestors may, no later than June 6, 2022, seek to be appointed as a lead plaintiff representative of the class through Kessler Topaz Meltzer & Check, LLP or other counsel, or may choose to do nothing and remain an absent class member. Kessler Topaz Meltzer & Check, LLP encourages AbbVie investors who have suffered significant losses to contact the firm directly to acquire more information.
