HAMILTON, Bermuda, Aug. 31, 2020 (GLOBE NEWSWIRE) -- Kiniksa Pharmaceuticals, Ltd. (Nasdaq: KNSA) (Kiniksa), a biopharmaceutical company focused on discovering, acquiring, developing and commercializing therapeutic medicines for patients with significant unmet medical need, presented findings from a real-world patient survey assessing the substantial impact of recurrent pericarditis on health-related quality of life at ESC Congress 2020, the annual meeting of the European Society of Cardiology.

The results of the patient survey highlight the severe and complex impact of recurrent pericarditis on both physical and mental quality of life. Furthermore, this study highlights the unmet need for a therapy that can rapidly resolve pericarditis episodes with the potential to prevent future recurrences, saidQasim Rizvi, Chief Commercial Officer and SVP of Operations at Kiniksa. The pivotal Phase 3 trial of rilonacept in recurrent pericarditis demonstrated a high degree of statistical significance on the primary and all major secondary endpoints, therefore we plan to submit an sBLA to the FDA in recurrent pericarditis this year. In preparation for commercialization we are continuing to generate additional evidence on the burden of recurrent pericarditis and also increasing disease awareness among payers, physicians and advocacy groups. We look forward to bringing this potential treatment to patients as soon as possible.

Martin LeWinter, MD, Larner College of Medicine, University of Vermont, was the lead author of the virtual poster Clinical Characteristics and Health-Related Quality of Life of Patients with Recurrent Pericarditis in the United States: Findings from a Patient Survey. The materials are available through the Science section of Kiniksas website (www.Kiniksa.com).

This study represents the first real-world analysis of patient-reported health-related quality of life in recurrent pericarditis, saidMartin LeWinter, MD, Larner College of Medicine, University of Vermont. Quantifying the impact of recurrent pericarditis on important health-related quality of life measures, including physical and emotional well-being, has enabled a more complete appreciation of the overall burden of recurrent pericarditis. For example, we found that pericarditis pain significantly impacts the ability to work, to be with family members, and to sleep for many patients at a level greater than that reported for many other debilitating diseases. These insights can help clinicians and patients evaluate treatment options and ultimately may contribute to improving outcomes.

Kiniksa reported positive data from RHAPSODY, a global, randomized withdrawal design, pivotal Phase 3 clinical trial of rilonacept in recurrent pericarditis. RHAPSODY showed that rilonacept improved clinically meaningful outcomes associated with the unmet medical need in recurrent pericarditis for patients in the study. The primary efficacy endpoint of time-to-first adjudicated pericarditis recurrence in the randomized withdrawal period was highly statistically significant: rilonacept treatment resulted in a 96% reduction in risk of recurrent pericarditis events (Hazard Ratio = 0.04, p<0.0001). All major secondary endpoints were also highly statistically significant.

Rilonacept was discovered and developed by Regeneron Pharmaceuticals, Inc. (Regeneron) and is approved by the U.S. Food and Drug Administration (FDA) under the brand name ARCALYST for the treatment of for Cryopyrin-Associated Periodic Syndromes (CAPS). Kiniksa licensed rilonacept from Regeneron in 2017 for evaluation in diseases believed to be mediated by both interleukin-1 alpha (IL-1) and interleukin-1 beta (IL-1), including recurrent pericarditis. The FDA granted Breakthrough Therapy designation to rilonacept for recurrent pericarditis in 2019 and Orphan Drug designation to rilonacept for pericarditis in 2020. Based on the Phase 3 RHAPSODY data, the Biologic License Application (BLA) for CAPS will transfer to Kiniksa, and the company plans to submit a supplemental Biologic License Application (sBLA) in recurrent pericarditis to the FDA this year.Upon receipt of FDA approval for rilonacept in recurrent pericarditis, Kiniksa will assume the sales and distribution of rilonacept for the approved indications inthe United Statesand evenly split profits on sales with Regeneron.

About Recurrent Pericarditis Recurrent pericarditis is a painful and debilitating autoinflammatory cardiovascular disease that typically presents with chest pain and is often associated with changes in electrical conduction and sometimes buildup of fluid around the heart, called pericardial effusion. Patients with pericarditis are deemed recurrent if they have an additional episode after a symptom-free period of 4-6 weeks and chronic if symptoms from any one episode last longer than three months. Recurrent pericarditis symptoms impair qualify of life, limit physical activities, and lead to frequent emergency department visits and hospitalizations. Claims analysis, cross validated with published research estimates, supports a prevalent population of approximately 40,000 patients in the U.S. seeking and receiving medical treatment. There are currently no FDA-approved treatments for recurrent pericarditis.

About Rilonacept Rilonacept is a weekly, subcutaneously-injected, recombinant fusion protein that blocks IL-1 and IL-1 signaling. Rilonacept was discovered and developed by Regeneron and is approved by the FDA under the brand name ARCALYST for the treatment of CAPS, specifically Familial Cold Autoinflammatory Syndrome and Muckle-Wells Syndrome. Rilonacept for the treatment of deficiency of the interleukin-1 receptor antagonist (DIRA) is currently pending FDA approval following the submission of an sBLA in June 2020. Rilonacept in recurrent pericarditis is an investigational drug. The FDA granted Breakthrough Therapy designation to rilonacept for recurrent pericarditis in 2019 and Orphan Drug designation to rilonacept for pericarditis in 2020.

Important information about ARCALYST (rilonacept) Injection

IL-1 blockade may interfere with immune response to infections. Serious, life-threatening infections have been reported in patients taking ARCALYST. ARCALYST should be discontinued if a patient develops a serious infection. Taking ARCALYST with TNF inhibitors is not recommended because this may increase the risk of serious infections.

Patients should not receive a live vaccine while taking ARCALYST. It is recommended that prior to initiation of therapy with ARCALYST patients receive all recommended vaccinations, as appropriate, including pneumococcal vaccine and inactivated influenza vaccine. In the initial development program for ARCALYST, six serious adverse reactions were reported by four patients: Mycobacterium intracellular infection, gastrointestinal bleeding and colitis, sinusitis and bronchitis and Streptococcus pneumoniae meningitis. The most commonly reported adverse reactions associated with ARCALYST were injection site reaction and upper respiratory tract infection. Patients should be monitored for changes in their lipid profiles and provided with medical treatment if warranted. Treatment with immunosuppressants, including ARCALYST, may result in an increase in risk of malignancies. Hypersensitivity reactions associated with ARCALYST administration in clinical studies have been rare. If a hypersensitivity reaction occurs, administration of ARCALYST should be discontinued and appropriate therapy initiated.
