Long-term goflkicept therapy for patients with idiopathic recurrent pericarditis: results of the interim analysis of an ongoing open-label extension study

Aim. To evaluate the long-term safety and efficacy of goflkicept treatment in patients with idiopathic recurrent pericarditis (IRP). Materials and methods. This report presents the interim analysis of an ongoing open-label extension (OLE) clinical trial of goflkicept in patients with IRP (NCT 05673902), as a continuation of the core study (NCT04692766). The study assessed the frequency of pericarditis recurrence, time to recurrence after 12 and 60 weeks of goflkicept therapy, changes in C-reactive protein level, chest pain intensity, pericardial effusion size, and adverse events (AEs). Results. All patients remained in clinical-laboratory remission during the 60 weeks of goflkicept treatment. The recurrence frequency was 31.3% (5/16) after 60 weeks and 90% (9/10) after 12 weeks of goflkicept treatment (p0.001). A total of 64 AEs were reported in 16 patients (94.1%), mostly of mild to moderate severity. The most common AEs were infections, occurring in 11 patients (64.7%). Nine serious adverse events were reported in 5 patients, none of which were considered drug-related. There were no deaths. Conclusion. Long-term goflkicept therapy resulted in a significant reduction in the risk of recurrence and prolonged remission without an increase in adverse events.
