Brief Summary
The purpose of this study is to determine if vitamin D as an adjuvant therapy can improve the outcome (i.e. fewer relapses) and the quality of life, including levels of physical activity, in children diagnosed Crohn's disease (CD).

Outcome Measures
Primary Outcomes (1)
Relapse
A relapse is defined as the occurrence of clinical symptoms (\> 2 bowel movements per day, abdominal pain, fever, weight loss, perianal disease or extra-intestinal symptoms) and a pediatric Crohn's disease Activity Index (PCDAI) less than 10. The PCDAI is a validated and reproducible tool that was developed by consensus at a meeting of pediatric (Inflammatory bowel disease) IBD experts and subsequently validated in 12 North American institutions. It includes 11 domains, with clinical symptoms, physical examination, laboratory parameters, and growth. The PCDAI score can range from 0-100, with higher scores signifying more active disease. A score \< 10 is consistent with inactive disease; 11-30 indicates mild disease; \> 30 suggests moderate to severe disease. The PCDAI has been used in many pediatric trials.
Within 52 weeks after randomization in the study

Between randomization and Week 52
Improvement of the Quality of life
At week 26 and week 52
Other Outcomes (1)
Change in the level of physical activities
Between randomization and 52 weeks
Study Arms (2)
Experimental Arm:
EXPERIMENTALExperimental: Vitamin D3 3000 or 4000 UI/day then 2,000 UI/day 3000 UI or 4,000 UI/day as induction therapy (according to weight) for 4 weeks then 2,000 UI/day as maintenance therapy for 48 weeks. The administration of vitamin D will be considered as an adjunct to conventional therapy (corticosteroids, exclusive enteral nutrition or immunosuppressive agents (ISA).
Control Arm:
ACTIVE COMPARATORActive Comparator: Vitamin D3 600 UI/day then 600 UI/day 600 UI/day as induction therapy for 4 weeks, then 600 UI/day as maintenance therapy for 48 weeks. The administration of vitamin D will be considered as an adjunct to conventional therapy (corticosteroids, exclusive enteral nutrition or immunosuppressive agents (ISA)).
Interventions
3000 or 4000 UI/ day: Weight at inclusion \< 40 kg : 1 ml per day of the selected concentration at induction and 1ml per day of the selected concentration at maintenance. Weight at inclusion ≥ 40 kg : 1 ml per day of the selected concentration at induction and 1 ml per day of the selected concentration at maintenance 600 UI/ day: Weight at inclusion \< 40 kg :1 ml per day of the selected concentration (600 IU) at induction and 1 ml per day of the selected concentration (600 IU) at maintenance. Weight at inclusion ≥ 40 kg : 1 ml per day of the selected concentration (600 IU) at induction and 1 ml per day of the selected concentration (600 IU) at maintenance
Eligibility Criteria
You may qualify if:
- Age at randomization between 4 and 17 years inclusively
- Receiving a stable dose for at least 4 weeks of any of the following drugs: Thiopurines, Methotrexate, or TNF-α inhibitors (Infliximab/Adalimumab)
You may not qualify if:
- History of surgery resulting in a permanent colostomy or ileostomy (because of the inability to calculate PCDAI at baseline)
- Patients who have already been included in the pilots vitamin D trials
- Patients actively enrolled in other CD drug trials.

- Masking Details
- The vitamin D will be donated by a pharmaceutical company. It will be dispensed in anonymized bottles with the content similar in color and taste in order to keep patients unaware of their allocation. We will implement a number of study maneuvers aimed at minimizing measurement biases. These include: (1) masking of the data; (2) documenting the use of major co-interventions such as other multivitamin supplements.
