- PDUFA goal date of March 21, 2021 - HAMILTON, Bermuda, Nov. 23, 2020 (GLOBE NEWSWIRE) -- Kiniksa Pharmaceuticals, Ltd. (Nasdaq: KNSA) (“Kiniksa”), a biopharmaceutical company with a pipeline of assets designed to modulate immunological pathways across a spectrum of diseases, today announced that the U.S. Food and Drug Administration (FDA) accepted the supplemental Biologics License Application (sBLA) for rilonacept in recurrent pericarditis. The FDA granted priority review to the application and assigned a Prescription Drug User Fee Act (PDUFA) goal date of March 21, 2021. Rilonacept is a weekly, subcutaneously-injected, recombinant dimeric fusion protein that blocks interleukin-1 alpha (IL-1?) and interleukin-1 beta (IL-1?) signaling. The FDA granted Breakthrough Therapy designation to rilonacept for the treatment of recurrent pericarditis in 2019 and Orphan Drug designation to rilonacept for the treatment of pericarditis in 2020. The regulatory submission was based on positive data from RHAPSODY, a pivotal Phase 3 trial of rilonacept in recurrent pericarditis. RHAPSODY met its prespecified primary and all major secondary efficacy endpoints, showing that rilonacept treatment in the trial improved clinically meaningful outcomes associated with the significant unmet medical need in recurrent pericarditis. RHAPSODY data were recently published in The New England Journal of Medicine simultaneously with a late-breaking scientific presentation at the American Heart Association’s Scientific Sessions 2020. “We are thrilled to receive the FDA’s acceptance of the sBLA submission for rilonacept in recurrent pericarditis with priority review, said Sanj K. Patel, Chief Executive Officer and Chairman of the Board of Kiniksa. “Rilonacept has the potential to become the first FDA-approved therapy for this painful and debilitating autoinflammatory disease. We are committed to bringing this potential treatment option to patients as soon as possible.” Rilonacept was discovered and developed by Regeneron Pharmaceuticals, Inc. (Regeneron) and is approved by the FDA for the treatment of Cryopyrin-Associated Periodic Syndromes (CAPS) under the brand name ARCALYST®. Kiniksa licensed rilonacept from Regeneron in 2017 for evaluation in diseases believed to be mediated by both IL-1? and IL-1?, including recurrent pericarditis. Based on positive RHAPSODY data, the Biologic License Application (BLA) for CAPS transferred to Kiniksa. If approved by the FDA for recurrent pericarditis, Kiniksa will take responsibility for sales and distribution of rilonacept for all the approved indications in the United States and evenly split profits with Regeneron, as described in the Rilonacept License Agreement. Kiniksa is obligated to pay regulatory milestones to Regeneron of up to an aggregate of $27.5 million through the time of a potential approval of rilonacept in recurrent pericarditis, of which $7.5 million is expected to be paid in the fourth quarter of 2020. Kiniksa continues to prepare for the potential commercial launch of rilonacept in recurrent pericarditis. The company has been generating evidence on disease burden, building disease awareness with payers, physicians, and advocacy groups, and establishing core capabilities such as distribution, patient services and data management. About RHAPSODY 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. There are currently no FDA-approved treatments for recurrent pericarditis. About the Rilonacept License Agreement with Regeneron About Rilonacept Important information about ARCALYST® (rilonacept) Injection 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.
