About Cardiol Therapeutics

Cardiol Therapeutics Inc. (NASDAQ: CRDL) (TSX: CRDL) is a clinical-stage life sciences company focused on the research and clinical development of cannabidiol as an anti-fibrotic and anti-inflammatory therapy for the treatment of cardiovascular disease ("CVD"). The Company's lead product candidate, CardiolRx™, is a pharmaceutically produced oral cannabidiol formulation that is being clinically developed for use in cardiovascular medicine. CardiolRx™ is currently being evaluated in a Phase II/III multi-national, randomized, double-blind, placebo-controlled study (the LANCER trial). LANCER is designed to evaluate the efficacy and safety of CardiolRx™ as a cardioprotective therapy to reduce major cardiovascular and respiratory events in patients hospitalized with COVID-19 who have a prior history of, or risk factors for, CVD, and to investigate the influence CardiolRx™ has on key biomarkers associated with heart disease. Cardiol has also received IND authorization from the FDA to conduct a Phase II multi-national, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of CardiolRx™ in acute myocarditis, which remains an important cause of acute and fulminant heart failure in young adults and is a leading cause of sudden cardiac death in people less than 35 years of age. In addition, Cardiol is developing a subcutaneous formulation of CardiolRx™ for the treatment of fibrosis and inflammation in the heart that is associated with the development and progression of heart failure - a leading cause of death and hospitalization in the developed world, with associated healthcare costs in the U.S. exceeding $30 billion annually.
