Objective: To evaluate rates of clinically inactive disease (CID) and remission in patients with juvenile idiopathic arthritis (JIA) receiving tofacitinib using the 2021 Juvenile Arthritis Disease Activity Score (JADAS) thresholds and American College of Rheumatology (ACR) criteria.
Methods: This post hoc analysis included patients with active JIA (polyarticular-course JIA, psoriatic arthritis, or enthesitis-related arthritis) enrolled in a phase III randomized withdrawal study of tofacitinib. In part 1 (weeks 0-18), patients received open-label tofacitinib.
Objectives: The aim of the study was to establish an international multicenter registry to collect data on patients with Multisystem Inflammatory Syndrome in Children (MIS-C), in order to highlight a relationship between clinical presentation, age of onset and geographical distribution on the clinical outcome.
Study Design: Multicenter retrospective study involving different international societies for rare immunological disorders.1009 patients diagnosed with MIS-C between March and September 2022, from 48 centers and 22 countries were collected.
Background: Tofacitinib is an oral Janus kinase inhibitor. This trial assessed the efficacy and safety of tofacitinib versus placebo in patients with polyarticular course juvenile idiopathic arthritis (JIA).
Methods: This double-blind, withdrawal phase 3 trial enrolled patients with polyarticular course JIA (extended oligoarthritis, rheumatoid factor-positive or rheumatoid factor-negative polyarthritis, or systemic JIA without active systemic features) aged 2 years to younger than 18 years, and was done at 64 centres of the Paediatric Rheumatology International Trials Organisation and Pediatric Rheumatology Collaborative Study Group networks in 14 countries.
