Study Endpoints

Primary Endpoints

Recurrence of pericarditis
24 weeks

proportions of patients free from a new episode of recurrent pericarditis\* from the timepoint of stopping the IL-1 blocker to Week 24

11-point NRS Pain Score
8 weeks

Change in pain score from baseline using 11-point NRS after 8 weeks of treatment. Nominal Rating Scale from 0 to 10, where 0 represents no pain and 10 maximum pain.

Extracellular Volume (ECV)
12 weeks post randomization

Change of ECV from baseline at 12 weeks, measured by cardiac Cardiac MRI. ECV is measuring the degree of edema and fibrosis. The unit of measure was percentage. It was the percentage of myocardial tissue that is extracellular space (i.e. fraction of the myocardium occupied by extracellular matrix and interstitial fluid).

Global Longitudinal Strain (GLS)
12 weeks post randomization

The outcome was the change in GLS from baseline at 12 weeks, measured by cardiac Cardiac MRI. GLS is a predictor of cardiac function. The unit of measure is percentage. It is the percent change in myocardial length relative to its original (end-diastolic) length along the long axis. Longitudinal strain during systole is usually negative, because the ventricle shortens; normal peak GLS in healthy adults is around -20% (i.e., 20% shortening relative to original length)

Secondary Endpoints

Percentage of days with no or minimal pain
24 weeks
Change in Left-ventricular Ejection Fraction (LVEF) From Baseline at 12 Weeks

Frequently asked questions about CardiolRx

What is CardiolRx used for?

CardiolRx is an investigational small molecule being developed for cardiovascular conditions, specifically acute myocarditis and recurrent pericarditis. It is a Phase 2 drug candidate from Cardiol Therapeutics Inc. (CRDL) that has been studied in clinical trials for these inflammatory heart conditions.

What does CardiolRx target?

CardiolRx is a small molecule therapeutic being developed by Cardiol Therapeutics Inc. (CRDL) for cardiovascular inflammatory conditions. While the specific molecular target is not disclosed in available information, it is being investigated for its effects on myocardial recovery in acute myocarditis and for reducing recurrent pericarditis episodes.

Who makes CardiolRx?

CardiolRx is being developed by Cardiol Therapeutics Inc., a biopharmaceutical company traded on the stock exchange under the ticker CRDL. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with acute myocarditis and recurrent pericarditis.

What phase is CardiolRx in?

CardiolRx is currently in Phase 2 clinical development. It has completed two Phase 2 trials: one in acute myocarditis (NCT05180240) and one in recurrent pericarditis (NCT05494788). A Phase 3 trial in recurrent pericarditis (NCT06708299) is currently recruiting participants.

What clinical trials is CardiolRx in?

CardiolRx has been studied in two completed Phase 2 trials: NCT05180240 in acute myocarditis with 109 participants and NCT05494788 in recurrent pericarditis with 27 participants. A Phase 3 trial, NCT06708299, is currently recruiting for recurrent pericarditis with a target enrollment of 110 participants.

Is CardiolRx FDA approved?

CardiolRx is not FDA approved. It is an investigational drug currently in clinical development. It has received orphan drug designation from the FDA, which is granted to drugs intended to treat rare diseases, but this does not mean it is approved for marketing.
