An Observational Study to Assess Change in Disease Activity and Adverse Events of Adalimumab in Chinese Pediatric Participants With Polyarticular Juvenile Idiopathic Arthritis (pJIA)

AbbVie20 enrolled

Overview

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease affecting children, characterized by chronic synovitis with systemic multi-organ damage. Polyarticular juvenile idiopathic arthritis (pJIA) is a subtype of JIA defined as disease involving more than five joints in the first 6 months of disease. This study will assess how safe and effective adalimumab (Humira®) is in treating pediatric participants with pJIA in China real-world setting. Adalimumab is an approved drug for the treatment of pJIA. Approximately 50 participants age 2 to 17 who are prescribed adalimumab for the treatment of pJIA in routine clinical practice will be enrolled at multiple sites in China. Participants will receive adalimumab per their physician's usual prescription. Individual data will be collected for 52 weeks. No additional study-related tests will be conducted during the routine physician visits. Only data which are routinely collected during a regular visit will be utilized for this study.

Outcomes

Primary Outcomes

Change from Baseline in Physician's Global Assessment (PhGA) of Participant's Disease Activity by Visual Analog Scale (VAS)

PhGA measured by 100 mm VAS. VAS scores range from 0 to 100 points, 0=very good and 100=very bad.

Time frame: Up to 52 Weeks

Change from Baseline in Participants Experiencing Joint Pain

Participants Experiencing Joint Pain

Time frame: Up to 52 Weeks

Change from Baseline in Participants Experiencing Joint Swelling

Participants Experiencing Joint Swelling

Time frame: Up to 52 Weeks

Number of Active Joints Count

Active joints are defined as joints with swelling not due to deformity or joints with limitation of passive motion \[LOM\] and with pain and/or tenderness. Higher scores represent higher disease activity.

Time frame: Up to 52 Weeks

Number of joints with limitation of passive motion (LOM)

Number of joints with LOM

Time frame: Up to 52 Weeks

Number of joints with pain on passive motion (POM)

Number of joints with POM

Time frame: Up to 52 Weeks

Change from Baseline of C-Reactive Protein (CRP) and/or Erythrocyte Sedimentation Rate (ESR) levels

CRP and/or ESR level assessed as part of the physician's site routine car

Time frame: Up to 52 Weeks

Change from Baseline in Parent's or Child's Global Assessment of Participant's Disease Activity (Pa/ChGA) by Visual Analog Scale (VAS)

Pa/ChGA measured by 100 mm VAS. VAS scores range from 0 to 100 points, 0=very good and 100=very bad.

Time frame: Up to 52 Weeks

Change from Baseline in Physical function measured by Childhood Health Assessment Questionnaire (CHAQ)

The CHAQ assessed physical function. Scores go from 0= no disability to 3 = severe disability.

Time frame: Up to 52 Weeks

Change from baseline in dosage of corticosteroid

Time frame: Up to 52 Weeks

Number of Participants with Adverse Events

An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with the treatment. The investigator assesses the relationship of each event to the use of study drug.
