Cardiol Therapeutics Announces Filing of 2020 Year-End Financial Statements and MD&A

Cardiol Therapeutics Inc. (TSX: CRDL) (OTCQX: CRTPF) (FSE: CT9) ("Cardiol" or the "Company"), a clinical-stage biotechnology company focused on developing innovative anti-inflammatory therapies for the treatment of cardiovascular disease, today filed its audited Financial Statements and Management's Discussion and Analysis for the year ended December 31, 2020. Both are available under the Company's profile on SEDAR at www.sedar.com and on the Company's website at www.cardiolrx.com.

David Elsley, President and Chief Executive Officer of Cardiol, commented: "2020 was a very exciting year for Cardiol Therapeutics. We made extraordinary progress in our research and clinical development programs, while significantly strengthening our financial position. We are particularly excited about the progress made across our research and development programs supporting the development of CardiolRx™, our pharmaceutically produced extra-strength oral formulation of cannabidiol and lead drug candidate for the treatment of acute inflammatory heart disease."

"Notably, receiving Investigational New Drug ("IND") approval from the FDA for our Phase II/III study in hospitalized COVID-19 patients with prior history of, or risk factors for cardiovascular disease ("CVD"), has presented a unique opportunity to investigate the impact of the cardioprotective properties of CardiolRx on a composite endpoint consisting of one or more of several common significant adverse outcomes in this patient population, including all-cause mortality, requirement for ICU admission and/or ventilatory support, as well as cardiovascular complications, including the development of heart failure, acute myocardial infarction, myocarditis, stroke, or new sustained or symptomatic arrhythmia. We believe successful outcomes from this study will support an emergency use authorization and/or a new drug application and will provide invaluable clinical data with respect to the therapeutic potential of CardiolRx™ in the treatment of other inflammatory heart diseases, including acute myocarditis and heart failure."

"Based on the large body of experimental evidence of the anti-inflammatory and cardioprotective properties of cannabidiol in models of cardiovascular disease, we also believe CardiolRx has the potential to offer a breakthrough therapy for acute myocarditis that would be eligible for designation as an orphan drug. Acute myocarditis is an inflammatory condition of the heart, usually resulting from viral infection, and currently represents a leading cause of sudden cardiac death in children and otherwise healthy young adults. In support of our plans to file an IND application with the FDA for an international Phase II clinical trial in acute myocarditis, we initiated and completed a Phase I double-blind, placebo-controlled, randomized study designed to assess safety, tolerability, and pharmacokinetics of single, followed by multiple day ascending doses of CardiolRx administered orally to 51 healthy adult subjects. As we anticipated, CardiolRx was shown to be well tolerated with no serious adverse events reported in the study."

"We also made significant progress in the development of a novel subcutaneous ("SC") formulation of cannabidiol that we believe represents an entirely new approach to the delivery of this important medicine for the treatment of chronic inflammatory heart disease. The first experimental data from Cardiol-sponsored research utilizing a SC cannabidiol formulation were accepted for presentation at the American College of Cardiology's 69th Annual Scientific Session & Expo together with the World Congress of Cardiology, held virtually from March 28 -30, 2020. The study found that cannabidiol administered SC significantly reduced hypertrophy and produced a dose-dependent reduction of key inflammation markers, decreases in fibrosis, and lower BNP expression in an experimental model of non-ischemic heart failure. These data support our long-standing view concerning the anti-inflammatory, anti-fibrotic, and cardioprotective properties of pharmaceutically produced cannabidiol, and serve as an encouraging scientific foundation for our plans to clinically develop a SC formulation of cannabidiol for the treatment of chronic heart failure, which remains a leading cause of death and hospitalization in North America, with associated annual healthcare costs in the U.S. alone exceeding $30 billion."

"In parallel with advancing important research and clinical development programs focused on inflammatory heart disease, we are also developing an attractive commercial opportunity for our high purity cannabidiol formulation by addressing poorly served segments of the $575 million medicinal cannabinoid market in Canada, particularly patients who should not take THC. Through an exclusive supply agreement with Medical Cannabis by Shoppers™, a subsidiary of Shoppers Drug Mart Inc., in late 2020 we commercially introduced Cortalex™, a THC-free (

"I believe the proposed acquisition of GW Pharma for US$7.2 billion in early 2021, together with the 2020 acquisition of MyoKardia for US$13 billion, underscores the potential value proposition for enterprises focused on cannabidiol-based medicines and on the development of new treatments for cardiovascular disease. With a robust research and development pipeline, world-class R&D collaborators, and an experienced management team, we are well positioned to build a leadership position in the development of therapies to address the underlying inflammatory component in heart disease."

Highlights during the 2020 Fiscal Period
