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 clinical studies to evaluate the efficacy and safety of CardiolRx™ in two orphan drug indications: (i) a Phase II multi-national, randomized, double-blind, placebo-controlled trial in acute myocarditis, an important cause of acute and fulminant heart failure in young adults and the leading cause of sudden cardiac death in people less than 35 years of age; and (ii) a Phase II multicenter open-label pilot study  in recurrent pericarditis (inflammation of the pericardium), which is associated with symptoms including debilitating chest pain, shortness of breath, and fatigue, and results in physical limitations, reduced quality of life, emergency department visits, and hospitalizations.

In addition, Cardiol is developing a subcutaneous formulation of CardiolRx™ for the treatment of fibrosis and inflammation 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.
