Summary

The purpose of this study is to compare the effectiveness of weekly subcutaneously administered Methotrexate for maintaining relapse-free sustained steroid/Enteral Nutrition -free 1-year remission compared with: * daily oral Azathioprine / 6 mercaptopurine in low risk paediatric Crohn's disease * subcutaneously administered adalimumab in high risk paediatric Crohn's disease

Detailed description

In this randomized controlled trial PIBDNet (pediatric inflammatory bowel diseases network) aims to compare the following treatment strategy by dividing patients into two risk groups for aggressive disease evolution: the effectiveness of Methotrexate versus Azathioprine / 6 mercaptopurine for the maintenance of remission in Crohn's disease in children who are at low risk for aggressive disease and the effectiveness of Methotrexate versus adalimumab in the high risk group. PIBDNet hypothesizes that Methotrexate is superior to Azathioprine / 6 mercaptopurine for maintaining remission in Crohn's disease in the low risk strata and adalimumab is superior to Methotrexate in the high risk strata. In addition, the ancillary study is planned to analyse of Adalimumab treated patients from inclusion (TOP-Down) versus patients switched to Adalimumab due to failure of immunomodulator therapy (STEP-Up).

Conditions

• Crohn's Disease

Interventions

Type	Name	Description
DRUG	Methotrexate	Subcutaneous methotrexate once weekly 15mg/m2 body surface area (19, 30), with a maximal dose of 25mg/week. Odansetron (Zofran) premedication (4-8mg 1Hour prior to injection) is recommended, folate acid substitution (15mg po, 3 days after Methotrexate injection, for children \<20kg: 1x 5mg) is recommended.
DRUG	Adalimumab	Subcutaneous Adalimumab started at a dose of 160mg followed by 80mg 2 weeks later and then 40mg every 2 weeks in patients over 40kg. In patients \< 40kg sc doses of Adalimumab are as follows: induction 160mg/1,73m2 BSA (max 160mg), followed by 80mg/1,73m2 Body surface area (max 80mg) 2 weeks later and maintenance of 40mg/1,73m2 Body surface area (max 40mg) every 2 weeks, all doses rounded up to the nearest 5 multiplications.
DRUG	Azathioprine / 6 Mercaptopurine	Oral Azathioprine /6mercaptopurine at a dose of 2.5 mg/kg once daily rounded to the nearest multiplication of 12.5mg or oral 6mercaptopurine at a dose of 1.5mg/kg once daily rounded to the nearest multiplication of 12.5mg.
