Overview
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 heart disease. The Company’s lead drug candidate, CardiolRx™ (cannabidiol) oral solution, is pharmaceutically manufactured and in clinical development for use in the treatment of heart disease. It is recognized that cannabidiol inhibits activation of the inflammasome pathway, an intracellular process known to play an important role in the development and progression of inflammation and fibrosis associated with myocarditis, pericarditis, and heart failure.
Cardiol has received Investigational New Drug Application authorization from the United States Food and Drug Administration to conduct clinical studies to evaluate the efficacy and safety of CardiolRx™ in two diseases affecting the heart: (i) 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; and (ii) 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 a leading cause of sudden cardiac death in people less than 35 years of age.
Cardiol is also developing a novel subcutaneously administered drug formulation of cannabidiol intended for use in heart failure – a leading cause of death and hospitalization in the developed world, with associated healthcare costs in the United States exceeding $30 billion annually.

Key Projects
Orphan Drug Program for Recurrent Pericarditis
In January 2023, Cardiol announced that the first patient has been enrolled in the company-sponsored Phase II open-label pilot study investigating the tolerance, safety, and efficacy of CardiolRx™ in patients with recurrent pericarditis. The study will also assess the improvement in objective measures of disease, and during an extension period, assess the feasibility of weaning concomitant background therapy including corticosteroids, while taking CardiolRx™.
Pericarditis refers to inflammation of the membrane or sac that surrounds the heart (the pericardium) that is most frequently triggered from a viral infection. Recurrent pericarditis is the most common complication following an initial acute episode of pericarditis, and patients may have multiple recurrences. Symptoms include debilitating chest pain, shortness of breath, and fatigue, resulting in physical limitations, reduced quality of life, emergency department visits, and hospitalizations. Infrequent but life-threatening complications associated with pericarditis include a large accumulation of pericardial fluid, scarring, and constriction of the heart which may limit heart function. The disease is diagnosed in 0.2% of all cardiovascular in-hospital admissions and is responsible for 5% of emergency room admissions for chest pain in North America and Western Europe. Recurrent pericarditis is the re-appearance of symptoms after a symptom-free period of at least 4 – 6 weeks following an initial acute episode of pericarditis. These recurrences appear in 15% to 30% of acute cases and usually within 18 months. Furthermore, up to 50% of patients with a recurrent episode of pericarditis experience more recurrences. Standard first-line medical therapy consists of non-steroidal anti-inflammatory drugs or aspirin with or without colchicine. Corticosteroids such as prednisone are second-line therapy in patients with continued recurrence and inadequate response to conventional therapy. The only FDA-approved therapy for recurrent pericarditis, launched in 2021, is generally used as a third-line intervention in patients with a third or fourth recurrence. The number of cases of patients seeking and receiving treatment for recurrent pericarditis annually in the U.S. is estimated at 38,000. Hospitalization due to recurrent pericarditis is often associated with a 5 – 8 day length of stay and cost per stay is estimated to range between $20,000 and $30,000 in the United States.
The Phase II pilot study is expected to enroll 25 patients at clinical centers in the United States that specialize in pericarditis care. The protocol has been designed in collaboration with thought leaders in pericardial disease. The study chairman is Dr. Allan L. Klein, director of the Center of Pericardial Diseases and professor of medicine, Heart and Vascular Institute at the Cleveland Clinic. The primary efficacy endpoint is the change, from baseline to eight weeks, in patient-reported pericarditis pain using an 11-point numeric rating scale (NRS). The NRS is a validated clinical tool employed across multiple conditions with acute and chronic pain, including previous studies of recurrent pericarditis. Additional endpoints during extension period include the NRS score after 26 weeks of treatment, and changes in inflammatory marker C-reactive protein (CRP), a commonly used clinical marker of inflammation.
“We are excited to be the first clinical center to administer this investigational drug in a patient with recurrent pericarditis, a debilitating inflammatory heart disease associated with symptoms that adversely affect quality of life and physical activity,” commented Dr. Paul C. Cremer, cardiologist, Center for the Diagnosis and Treatment of Pericardial Diseases, Section of Cardiovascular Imaging, Department of Cardiovascular Medicine, Heart, Vascular and Thoracic Institute, Cleveland Clinic, and study site principal investigator. “Along with other collaborating research centers throughout the U.S., we look forward to full enrollment of participants into this pilot study and to determining the potential of this therapy to treat pericarditis and to reduce the risk of its recurrence.”
In the US, an orphan drug designation is granted for pharmaceuticals being developed to treat medical conditions affecting fewer than 200,000 people. These conditions are referred to as orphan diseases. The assignment of orphan status to a disease and to drugs developed to treat it is a matter of public policy in many countries and has yielded medical breakthroughs that might not otherwise have been achieved. In the US and the European Union, orphan drugs are eligible for accelerated marketing approvals and companies developing orphan drugs typically receive other incentives, including a prolonged period of market exclusivity that can extend over seven years, during which the drug developer has sole rights to market the drug.
Recurrent pericarditis is an orphan disease in the United States, thereby making CardiolRx™ eligible for orphan drug status under the FDA’s Orphan Drug Designation program.
Independent advisors and key investigators comprising six highly distinguished thought leaders in cardiology from the Cleveland Clinic, the Mayo Clinic, the Monash Victoria Heart Institute, and the University of Virginia, have been established to design, oversee, and guide Cardiol’s Phase II multi-center open-label pilot study in patients with recurrent pericarditis.
Orphan Drug Program for Acute Myocarditis
In August 2022, Cardiol enrolled its first patient in ARCHER, the company’s multi-center, international, double-blind, randomized, placebo-controlled trial designed to study the safety and tolerability of CardiolRx™, as well as its impact on myocardial recovery, in patients presenting with acute myocarditis.
Myocarditis is an acute inflammatory condition of the heart muscle (myocardium) characterized by chest pain, impaired cardiac function, atrial and ventricular arrhythmias, and conduction disturbances. Although the symptoms are often mild, myocarditis remains an important cause of acute and fulminant heart failure and is a leading cause of sudden cardiac death in people under 35 years of age. Although viral infection is the most common cause of myocarditis, the condition can also result from bacterial infection, commonly used drugs and mRNA vaccines, as well as therapies used to treat several common cancers, including chemo-therapeutic agents and immune checkpoint inhibitors.
In a proportion of patients, the inflammation in the heart persists and causes decreased heart function with symptoms and signs of heart failure, and as such treatment is based on standard-of-care recommendations for heart failure. This includes diuretics, ACE inhibitors, angiotensin receptors blockers, beta blockers, and aldosterone inhibitors. For those with a fulminant presentation, intensive care is often required, with the use of inotropic medications (to increase the force of the heart muscle contraction). Severe cases frequently require ventricular assist devices or extracorporeal oxygenation and may necessitate heart transplantation.
There are no FDA-approved therapies for acute myocarditis. Patients hospitalized with the condition experience an average 7-day length of stay and a 4 – 6% risk of in-hospital mortality, with average hospital charge per stay estimated at $110,000 in the United States.
“The US orphan drug program was successfully utilized to accelerate the first FDA approval of CBD for the treatment of rare forms of pediatric epilepsy, and significant shareholder value was created in the process,” stated Cardiol President and CEO David Elsley. “Given the mortality and significant morbidity risk associated with acute myocarditis, we believe there is a similar opportunity in pursuing an expedited development program of our CardiolRx™ pharmaceutical CBD formulation for this serious orphan disease which has no accepted standard of care.”
The primary efficacy endpoints of the ARCHER trial consist of extracellular volume (ECV) and global longitudinal strain (GLS). The secondary efficacy endpoint is left ventricular ejection fraction. Since people with acute myocarditis have impaired heart function, current treatment is based on standard-of-care recommendations for heart failure. This includes diuretics, ACE inhibitors, angiotensin receptors blockers, beta blockers, and aldosterone inhibitors. For those with a severe and sudden onset presentation, intensive care is often required, with the use of inotropic medications (to increase the force of the heart muscle contraction) and occasionally, heart-lung bypass or ventricular assist devices. There is otherwise no specific treatment for acute myocarditis although some patients have responded to immuno-suppressive therapy (azathioprine) in combination with steroids, but the data are not conclusive enough for this to be the recommended therapy.
An independent clinical steering committee, comprising 10 highly distinguished thought leaders in cardiology from the Cleveland Clinic, the Mayo Clinic, the Houston Methodist DeBakey Heart and Vascular Center, the University of Ottawa Heart Institute, McGill University Health Centre, the University of Pittsburgh Medical Center, University Medicine Berlin, Tel Aviv “Sourasky” Medical Center, São Paulo University Medical School, and Pitié Salpêtrière Hospital (Sorbonne University), has been established to design, oversee, and guide Cardiol’s Phase II multi-national ARCHER trial in acute myocarditis.
Cardiol Therapeutics’ Heart Failure Program
Heart failure affects more than 64 million people globally and associated healthcare costs exceed $30 billion annually in the U.S. alone. Heart failure is a chronic, progressive syndrome in which the heart muscle is unable to pump enough blood to meet the body’s needs for blood and oxygen. People with heart failure suffer from shortness of breath, rapid heart rate, edema, reduced exercise capacity, often struggle with simple daily activities, and are frequently hospitalized. For many, these symptoms significantly reduce their quality of life. Known causes of heart failure include ischemic heart disease and myocardial infarction (heart attack), hypertension, valvular heart disease, inflammatory diseases of the heart such as myocarditis and cardiomyopathies, anti-cancer therapies, and inherited metabolic diseases.
Heart failure remains a leading cause of morbidity and mortality worldwide and persists as a growing health and economic burden. In the United States alone, 6 million people over the age of 20 are living with heart failure, and this number is projected to increase to >8 million by 2030. The total annual cost attributed to heart failure is projected to increase to $69.8 billion by 2030. Recent reporting indicates that in the United States there are 3.3 million physician visits with a primary diagnosis of heart failure annually, and 1.5 million emergency department visits attributable to the syndrome. Total deaths attributed to heart failure annually in the United States have been reported in the range of 86,000 to >300,000, and hospitalizations range from 800,000 to 1.3 million. The 5-year mortality rate for those with heart failure has been reported at 52.6% overall.
Cardiol is developing CRD-38, a novel proprietary drug formulation designed to deliver cannabidiol by subcutaneous administration. They are undertaking IND-enabling activities to support clinical evaluation of CRD-38 as a therapeutic strategy in heart failure care – a leading cause of death and hospitalization in the developed world, with associated health-care costs in the United States exceeding $30 billion annually. In addition, Cardiol has an active discovery program focused on developing additional novel therapeutic approaches to address inflammation and fibrosis associated with the development and progression of heart diseases.
Published third-party research has shown that cannabidiol reduces inflammatory activation of the endothelial lining of blood vessels and aids endothelial vasorelaxation, resulting in improved blood flow. Cannabidiol has also been shown to attenuate a number of measures of inflammation in models of diabetes, a common comorbidity in heart failure patients, and to reduce myocardial fibrosis in a model of inflammatory heart disease.
Cannabidiol is lipid soluble, virtually insoluble in water, highly sensitive to deactivation in the liver via first-pass metabolism when taken orally and is rapidly cleared from the body. This results in a low overall bioavailability when taken orally. Cardiol’s subcutaneously administered drug formulation is designed to minimize first-pass metabolism, optimize and maintain blood levels of the drug, and target inflammation and increased fibrosis in the heart. Cardiol believes that overcoming the low bioavailability issues associated with cannabidiol will significantly broaden the therapeutic potential of this molecule.
