Abstract
BACKGROUND Rilonacept, a once-weekly interleukin-1 alpha and beta cytokine trap, reduced pericarditis recurrence in the phase 3 study, RHAPSODY (Rilonacept Inhibition of Interleukin-1 Alpha and Beta for Recurrent Pericarditis: A Pivotal Symptomatology and Outcomes Study). The RHAPSODY long-term extension further explored recurrent pericarditis natural history and treatment duration decision-making during 24 additional months of open-label rilonacept treatment. METHODS AND RESULTS Seventy-four patients commenced the long-term extension, with a median (maximum) total rilonacept duration of 22 (35) months. Individually, 18 months after the most proximal pericarditis recurrence, investigators decided to continue rilonacept on study, suspend rilonacept for off-treatment observation (rescue allowed), or discontinue the study. The annualized incidence of pericarditis recurrence on rilonacept up to the 18-month decision milestone was 0.04 events/patient-year versus 4.4 events/patient-year prestudy while on oral therapies. At the 18-month decision milestone, 64% (33/52) continued rilonacept, 15% (8/52) suspended rilonacept for observation, and 21% (11/52) discontinued the study. Among the 33 patients (1/33; 3.0%) continuing rilonacept (median time to recurrence could not be estimated due to too few events), a single recurrence occurred 4 weeks after a treatment interruption. Among patients suspending rilonacept, 75% (6/8) experienced recurrence (median time to recurrence, 11.8 weeks [95% CI, 3.7 weeks to not estimable]). There was a 98% reduction in risk of pericarditis recurrence among patients continuing rilonacept treatment after the 18-month decision milestone versus those suspending treatment for observation (hazard ratio, 0.02; P<0.0001). CONCLUSIONS In the RHAPSODY long-term extension, continued rilonacept treatment resulted in continued response; treatment suspension at the 18-month decision milestone was associated with pericarditis recurrence.

Abstract
Importance Pericarditis is the most common form of pericardial disease. Recurrence of pericarditis affects 15% to 30% of patients after the initial episode of pericarditis. Up to 50% of patients with the first recurrence have additional recurrences. These patients often progress to have colchicine-resistant and corticosteroid-dependent disease. Rapidly evolving cardiac magnetic resonance imaging techniques and novel targeted therapies have paved the way for imaging-guided therapy for recurrent pericarditis. However, the optimal application of these recent advances remains unclear. Observations A search was conducted using the PubMed and Cochrane databases for English-language studies, management guidelines, meta-analyses, and review articles published until April 2022 on recurrent pericarditis. Following the 2015 European Society of Cardiology guidelines for the diagnosis and management of pericardial diseases, new clinical trials and registry data have emerged that demonstrate the efficacy of interleukin-1 blockers in recurrent pericarditis. In addition, new observational data have come to light supporting the use of cardiac magnetic resonance imaging in the diagnosis, risk stratification, and management of such patients. Conclusions and Relevance Advances in imaging and targeted therapies have led to a paradigm shift in the management of recurrent pericarditis. This narrative review summarizes the established and emerging data on the diagnosis and treatment of recurrent pericarditis with special emphasis on the role of cardiac magnetic resonance imaging and interleukin-1 blockers in the current era of tailored therapy for recurrent pericarditis.
