About this study

Official title: CardiolRxTM in Recurrent Pericarditis (MAVERIC Phase 3) A Randomized, Double-blind, Placebo-controlled Trial

Multi-center, randomized, double-blind, placebo-controlled, phase-3 Trial. Patients with a history of recurrent pericarditis who are being treated with an IL-1 blocker for at least 12 months, scheduled to be discontinued, will be approached for potential trial participation.

Double-blind treatment will be initiated 10 - 16 days prior to the last scheduled dose of the IL-1 blocker and continued for 24 weeks.

The objective is to assess whether patients remain free of pericarditis recurrence while receiving CardiolRx.

Read the detailed description

Double-blind, randomized, placebo-controlled Phase-3 trial. The primary objective is to assess whether patients remain free of pericarditis recurrence while receiving CardiolRx.

Before any trial-related procedure is performed, written informed consent will be obtained. After informed consent is obtained, patients will be screened for eligibility.

The highest NRS pain score within the past 7 days is to be assessed prior to randomization at Visit 1 (Day 1). Baseline blood samples for central laboratory assessment of hs-CRP and pharmacokinetic assessments should also be collected prior to randomization at Visit 1 (Day 1).

All other screening assessments will be performed at any time within 7 days prior to randomization at Visit 1 (Day 1) and include the following: Physical examination, vital signs, 12-lead ECG; C-SSRS and blood draws for local laboratory assessments (see Section 17.2).

Eligible patients will be randomized at Visit 1 (Day 1) to either CardiolRx or matching placebo in a 1:1 ratio. Double-blind trial therapy will be initiated in the evening of Day 1, 10 - 16 days (no additional time window is allowed) prior to the last scheduled dose of the IL-1 blocker and after all baseline assessments are completed. Trial therapy will be administered for 24 weeks.

Vital signs, ECG recording and blood draws for local and central laboratory analyses will be carried out at selected visits. Concomitant medications and (S)AEs will be recorded at all visits.

Final efficacy assessments will take place at Visit 9, 24 weeks after randomization and start of trial therapy and include a physical exam, vital signs, pain score NRS collection, a 12-lead ECG, a C-SSRS, as well as blood draws for local and central laboratory assessments.

A virtual safety follow-up visit (Visit 10) will be scheduled 4 weeks after the last trial therapy administration.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. time to pericarditis recurrence

    time to a new episode of recurrent pericarditis* from the timepoint of stopping the IL-1 blocker to Week 24

    Measured: 24 weeks

Secondary outcomes (2)
  1. Proportions of patients free from a new episode of recurrent pericarditis

    Proportions of patients free from a new episode of recurrent pericarditis from the timepoint of stopping the IL-1 blocker to week 24

    Measured: 24 weeks

  2. Percentage of days with no or minimal pain

    The percentage of days with no or minimal pain as assessed by an NRS score ≤ 2 from the timepoint of stopping the IL-1 blocker to Visit 9 (Week 24)

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing CardiolRx in people with Recurrent Pericarditis, run by Cardiol Therapeutics Inc. at 27 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 10 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 27 sites in United States, Italy, Canada, Greece. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Andrea B Parker, MSc., PhD (+1 289 910 0862, andrea.parker@cardiolrx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

time to pericarditis recurrence (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06708299, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Sep 2026.
