Official Title: Continuation of a Pilot Open-Label Study of IL 1 Trap in Adult Subjects With Autoinflammatory Diseases: A Therapeutic Approach to Study Pathogenesis
Brief Summary:
Autoinflammatory diseases are illnesses characterized by episodes of inflammation that, unlike autoimmune disorders, lack the production of high titer autoantibodies or antigen-specific T cells. There is growing genetic and clinical evidence that Interleukin-1 (IL-1) plays a pathogenic role in several of these diseases. This exploratory study aims to examine the utility of the experimental drug candidate, IL 1 Trap (Regeneron Pharmaceuticals, Inc.) in the treatment of adult subjects with the autoinflammatory disorders Neonatal Onset Multisystem Inflammatory Disease (NOMID), Muckle-Wells Syndrome (MWS), and Familial Cold Autoinflammatory Syndrome (FCAS), Familial Mediterranean Fever (FMF), and adult Still's disease. FMF is associated with mutations in pyrin encoding MEFV. NOMID, MWS and FCAS are associated with mutations in cryopyrin-encoding CIAS1.
This pilot study is designed to address: 1) the utility of IL 1 Trap in the treatment of subjects with diseases known to respond to IL-1 blockade (NOMID/MWS/FCAS) as shown by response to treatment with anakinra [Kineret]; 2) the response to IL-1 blockade of subjects with Adult Still's disease and colchicine-resistant FMF once the efficacy of IL-1 Trap has been established in NOMID/MWS/FCAS subjects; and 3) the biochemistry and genetics of autoinflammatory diseases and IL-1 related inflammation.
IL-1 Trap is a recombinant fusion protein with picomolar affinity for IL-1 and a half-life of approximately 7.5 days in humans. This agent is currently in Phase 2 clinical studies for the treatment of rheumatoid arthritis and initial studies have shown activity against clinical and biochemical indicators of inflammation. Compared with anakinra, this agent may exhibit improved dosing convenience, potential for fewer injection site reactions, and improved efficacy due to the extremely high
