Study of Sarilumab Given by Subcutaneous Injection to Children and Teens Aged 1 to 17 with Systemic Juvenile Idiopathic Arthritis Including a Long-Term Extension Phase

What this Trial Is About

Researchers are studying the use of sarilumab, a drug given by injection, in children and adolescents aged 1 to 17 years who have systemic juvenile idiopathic arthritis sJIA. The study aims to understand how the drug behaves in the body, its effects, and its long-term safety for treating this condition. This trial is a phase 2, open-label study sponsored by Sanofi, designed to find the best dose and treatment schedule for young patients with sJIA. Participants will receive sarilumab injections under the skin at doses that increase during the study based on body weight. The treatment includes a 12-week core phase where patients receive the drug, followed by a 144-week extension phase for continued treatment. After completing treatment, a 6-week follow-up period will monitor patients. The study includes careful dose adjustments and long-term observation to assess the drugs impact. Throughout the study, participants will undergo various assessments including blood tests to measure drug levels, evaluations of disease activity using scales like the Investigator Global Assessment and ParentPatient Global Assessment, and tracking of symptoms and medication use. Safety will be monitored continuously by recording any side effects or local reactions to injections. The total participation time is about 166 weeks, during which the researchers will collect data on how well sarilumab works and how safe it is for children and adolescents with sJIA.
