About Cardiol Therapeutics
Cardiol Therapeutics Inc. (NASDAQ: CRDL) (TSX:
CRDL) is a late-stage life sciences company focused on advancing the development of anti-inflammatory and anti-fibrotic therapies
for heart disease. The Company's lead small-molecule drug candidate, CardiolRx™, modulates inflammasome pathway activation,
an intracellular innate immune system response known to play an important role in the development and progression of inflammation and
fibrosis associated with pericarditis, myocarditis, and heart failure.
The MAVERIC Program is evaluating CardiolRx™
for the treatment of recurrent pericarditis, an inflammatory disease of the pericardium associated with symptoms including debilitating
chest pain, shortness of breath, and fatigue, which can lead to physical limitations, reduced quality of life, emergency department visits,
and hospitalizations. The program comprises the completed Phase II MAvERIC-Pilot study (NCT05494788) and the ongoing pivotal Phase III
MAVERIC trial (NCT06708299). The U.S. FDA has granted Orphan Drug Designation to CardiolRx™ for the treatment of pericarditis,
including recurrent pericarditis.
The ARCHER Program also studied CardiolRx™,
specifically in acute myocarditis--an important cause of acute and fulminant heart failure in young adults and a leading cause of sudden
cardiac death in individuals under 35 years of age. The program comprises the completed Phase II ARCHER study (NCT05180240), which evaluated
the safety, tolerability, and efficacy of CardiolRx™ in this patient population.
The Company is also developing CRD-38, a novel, subcutaneously
administered drug formulation intended for the treatment of inflammatory heart disease, including heart failure--a leading cause of death
and hospitalization in the developed world, with associated healthcare costs in the United States exceeding US$30 billion per year.
