All Clinical Trials for KINERET

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00069329 ↗ Anakinra to Treat Patients With Neonatal Onset Multisystem Inflammatory Disease Terminated National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Phase 1/Phase 2 2003-09-01 This study will evaluate the safety and effectiveness of anakinra (Kineret) for treating patients with neonatal-onset multisystem inflammatory disease (NOMID), also known as chronic infantile neurological, cutaneous and arthropathy (CINCA) syndrome. This disease can cause rash, joint deformities, brain inflammation, eye problems, and learning difficulties. Immune suppressing medicines commonly used to treat other pediatric rheumatologic diseases do not suppress NOMID symptoms and, if used long-term and in high doses, can cause harmful side effects. Anakinra, approved by The Food and Drug Administration for treating rheumatoid arthritis in adults, blocks a substance called IL-1 that may be an important factor in causing the inflammation in NOMID.
NCT00094900 ↗ Interleukin-1 Trap to Treat Autoinflammatory Diseases Completed National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Phase 2 2004-10-01 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 affinity of IL-1Trap for its target. In this study, biochemical, genetic, and clinical correlates of autoinflammatory disease will initially be measured at baseline following a withdrawal of any TNF or IL-1 inhibitor medications where applicable. Subjects will receive a course of therapy with IL-1 Trap that is predicted to provide an estimated 3-4 weeks of anti-inflammatory activity. Clinical, biochemical, and genetic correlates of inflammation will be measured at appropriate intervals to ascertain response and to further elucidate disease mechanisms. Subjects will be eligible, based on clinical response, to enter a 1- year extension phase with IL-1 Trap. Those subjects who complete the 1-year extension phase, and maintain improved clinical and laboratory parameters compared to baseline values, may continue to receive study medication at their current dose until the study drug is commercially available. Investigator comment: This protocol (from the NIH standpoint) is a continuation of the ongoing protocol 05-AR-0014, with a new change in study sponsor, the NIH replacing Regeneron as sponsor. this protocol therefore still contains background and procedural information that refer to patients with FMF and FCAS and or MWS and Still's disease, however only patients with Still's disease will be newly enrolled from this point on, enrollment for the FCAS and or MWS patients has already been completed and it has been decided to not enroll any more FMF patients because the number of subjects is too low to reach reasonable conclusions, in addition it has been difficult to recruit patients that are eligible. The background section and study procedures have largely been left as in the currently IRB approved protocol.
NCT00117091 ↗ Anakinra (Kineret®) in Combination With Disease Modifying Anti-Rheumatic Drugs (DMARDS) in Subjects With Active Rheumatoid Arthritis (RA) Completed Amgen Phase 3 1969-12-31 The purpose of this study is to evaluate the percentage of subjects in Australian clinical practice continuing treatment with Anakinra (Kineret®) at the end of study week 48 in subjects with active RA. The continued use of Kineret® will be based on pre-defined response assessment criteria for subjects with active RA.
NCT00121043 ↗ Evaluating Kineret® (Anakinra) in Rheumatoid Arthritis (RA) Subjects Using aSelf-Reported Questionnaire Completed Amgen Phase 4 1969-12-31 The primary purpose of this study is to assess the ease-of-use of SimpleJectTM compared to pre-filled syringe(s) when using Kineret® in RA subjects. The secondary purpose of this study is to assess the level of fear and anxiety associated with the use of both injection methods, to assess safety when using SimpleJectTM and to evaluate the Ease-of-Administration Questionnaire (EAQ) in terms of the quality of items, item performance, and the instrument reliability.
NCT00121056 ↗ REKinDLE: Registry With Enbrel® or Kineret® in a Database Using Longitudinal Evaluations Completed Amgen 2002-09-01 The purpose of this study is to determine if Enbrel® or Kineret® will have a positive effect on subject functionality as measured by the Health Assessment Questionnaire Disability Index (HAQDI).
