Study Summary

Among patients with colchicine-resistant glucocorticoid-dependent idiopathic RP (idiopathic recurrent pericarditis during at least a second recurrence, having met the 2015 European Society of Cardiology criteria for pericarditis at least once), HCQ 400mg daily is associated with a reduce the risk of recurrence.

The above hypothesis will be tested with a randomized, prospective, parallel, open label clinical trial. The expected study duration is approximately 12 months from the time the first subject is enrolled (planned for February 2023) to the time of study's termination date (December 2024). The researchers will obtain approval by the institutional review board (IRB).

Eligibility Criteria

Inclusion

Inclusion Criteria:

Male or female patients aged≥18 years
Idiopathic recurrent pericarditis with at least 2 recurrences
Recurrent pericarditis defined as a first episode of acute pericarditis followed byrecurrences (at least two recurrences for this study). First episode of pericarditisis diagnosed when at least two of the following criteria were present: pericarditistypical chest pain (sharp and pleuritic, improved by sitting up and leaning forward),pericardial friction rubs, widespread ST segment elevation or PR interval (PR)depressions not previously reported, and new or worsening pericardial effusion.Recurrence is diagnosed when chest pain recurs and one or more of the following signsis present: fever, pericardial friction rub, ECG changes, echocardiographic evidenceof new or worsening pericardial effusion, and elevations in the white blood cellcount, erythrocyte sedimentation rate or C-reactive protein. To be enrolled in thisstudy, elevation of C-reactive protein is mandatory both in the first attack and inthe following recurrences. The investigators differentiate recurrences from incessantpericarditis, term used to define patients with continued activity of pericarditis (with a symptom-free interval of < 6 weeks)
Specific aetiologies excluded, including tuberculous, neoplastic or purulentaetiologies, post-cardiac injury syndromes, and rheumatic autoimmune diseases.
Female subjects must be postmenopausal, or incapable of pregnancy or permanentlysterile, or if of childbearing potential must agree to use highly-effective method ofcontraception.
Signed written informed consent by the patient for participation in the study andagreement to comply with the medication and the follow-up schedule.

Exclusion

Exclusion Criteria:

Ophthalmologic contraindications
Structural heart disease
Corrected QT interval >440msec in men and >450msec in women
Left ventricular hypertrophy >13mm in men and >11mm in woman
Known allergy or intolerance to hydroxychloroquine
Life expectancy of < 12 months
Complex congenital heart disease
History of ventricular arrhythmias other than isolated extrasystoles
Women who are pregnant (as evidenced by pregnancy test if pre-menopausal)
Known channelopathy such as Brugada syndrome, long QT syndrome, or Catecholaminergicmonomorphic ventricular tachycardia
On the heart transplant list

Study Description

Recurrent pericarditis (RP) along with pericardial tamponade and constrictive pericarditis are potential complications of acute pericarditis. They appear most frequently in secondary forms of pericarditis as compared with idiopathic acute pericarditis. Among the above-mentioned complications, RP is a highly problematic and disabling condition, which severely impairs the quality of life of affected patients, since it often requires emergency department visits and hospitalizations.

Moreover, the side effects of treatment constitute an additional concern both for the managing physicians and affected patients. In the most recent guidelines for the diagnosis and management of pericardial diseases of the European Society of Cardiology (ESC), a stepwise approach has been proposed for the treatment of RP including 4 treatment lines according to disease severity and individual response to treatment. Among them hydroxychloroquine (HCQ), an anti-malarial drug with immunomodulatory properties could potentially have a role as a third step treatment. HCQ, is an established treatment for all patients with systemic lupus erythematosus (SLE) including those with serositis (pericarditis, pleuritis) but data on HCQ efficacy for refractory idiopathic RP (IRP) are very scant.

The potential Anti-interleukin-1 agents are characterized by some disadvantages such as a long duration of therapy as well as high costs. In addition to this, only patients with a clear inflammatory pattern are candidates. Patients with mild or doubtful symptoms and/or normal or near normal levels of C-Reactive protein are not good candidates for anti-IL-1 therapy.

The investigators propose a randomized, prospective, parallel, open label, clinical trial, which will provide data on the efficacy and safety of HCQ in colchicine-resistant glucocorticoid-dependent idiopathic RP. The trial will have two study arms: HCQ 400mg daily vs. Colchicine continued. Patients with RP (idiopathic recurrent pericarditis during at least a second recurrence, having met the 2015 European Society of Cardiology criteria for pericarditis at least once) will be randomized to HCQ vs. Colchicine and will receive optimal post-recurrence care (increase the dose of methylprednisolone by 8 mg and then decrease by 2 mg every 2 weeks) in both arms.
