Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessing Humira persistence | Up to 30 days after the last dose of the study drug (approximately 52 weeks) | Persistence is defined as the time (in days) between the start date of HUMIRA (adalimumab) treatment and the earliest date of discontinuation of Humira (adalimumab) or drop out of study, or lost to follow up. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients with Humira adherence | Up to Week 48 of treatment | The adherence to Humira will be assessed. |
| Proportion of patients with 50% American College of Rheumatology (ACR) pediatric responses | Up to Week 48 of treatment | It is defined as 50% improvement respectively in a minimum of three core set criteria with worsening of one variable by no more than 30%. |
| Proportion of patients with 70% American College of Rheumatology (ACR) pediatric responses | Up to Week 48 of treatment | It is defined as 70% improvement respectively in a minimum of three core set criteria with worsening of one variable by no more than 30%. |
| Change from baseline in physician overall disease activity | From Week 0 to Week 48 of the treatment period | This is measured using Visual Analog Scale (VAS). |
| Change from baseline in patient (if appropriate in age) or parent overall well-being | From Week 0 to Week 48 of the treatment period | This is measured using Visual Analog Scale (VAS). |
| Assessing Childhood Health Assessment Questionnaire-Disability Index (CHAQ-DI) score | Up to 48 weeks of the treatment period | Childhood Health Assessment Questionnaire-Disability Index (CHAQ-DI) score is assessed. |
| Change from baseline in number of joints with active arthritis | From Week 0 to Week 48 of the treatment period | The change in number of joints with active arthritis is assessed. |
| Proportion of patients with 30% American College of Rheumatology (ACR) pediatric responses | Up to Week 48 of treatment | It is defined as 30% improvement respectively in a minimum of three core set criteria with worsening of one variable by no more than 30%. |
| Change from baseline in Erythrocyte Sedimentation Rate (ESR) | From Week 0 to Week 48 of the treatment period | The Erythrocyte Sedimentation Rate is assessed. |
| Change from baseline in 10-joint Juvenile Arthritis Disease Activity Score (JADAS10) | From Week 0 to Week 48 of the treatment period | 10-joint Juvenile Arthritis Disease Activity Score is assessed. |
| Proportion of patient with low diseases activity (1.1 - 2 score) | Up to 48 weeks of the treatment period | This is assessed based on JADAS10 score. |
| Proportion of patient with moderate disease activity (2.1 - 4.2 score) | Up to 48 weeks of the treatment period | This is assessed based on JADAS10 score. |
| Proportion of patients with missed dosed of HUMIRA | Up to 48 weeks of the treatment period | The proportion of patients with missed dosed of HUMIRA is assessed. |
| Proportion of patients with predefined Extra-articular manifestations (EAMs) | Up to 48 weeks of the treatment period | The proportion of patients with predefined EAMs is assessed. |
| Proportion of patients with any comorbidity | Up to 48 weeks of the treatment period | Patients with any comorbidities are assessed. |
| Change from baseline in number of joints with limited range of motion | From Week 0 to Week 48 of the treatment period | The change in number of joints with limited range of motion is assessed. |
