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 anti-inflammatory and anti-fibrotic therapies for the treatment of cardiovascular diseases ("CVD"). The Company's lead product candidate, CardiolRx™, is an oral pharmaceutical that is being clinically developed for use in CVD.

Cardiol has 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 (the "ARCHER" 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 multi-center 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, CardiolRx is 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 is also developing a subcutaneous formulation of cannabidiol targeting the inflammation and fibrosis 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.
