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 with newly diagnosed Crohn's disease (CD).

Outcome Measures
Primary Outcomes (1)
Occurrence of at least one relapse within 52 weeks after randomization in the trial.
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) \> 30. 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.

Study Arms (2)
Vitamin D3 3000 or 4000 UI/day then 2,000 UI/day
EXPERIMENTAL3000 UI or 4,000 UI/day as induction therapy (according to weight) for 4 weeks then 2,000 UIday 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)).
Vitamin D3 800 UI/day then 800 UI/day
ACTIVE COMPARATOR800 UI/day as induction therapy for 4 weeks, then 800 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
* Weight at inclusion \< 40 kg : 3 capsules of 1000 UI per day at induction and 2 capsules of 1000 UI per day at maintenance. * Weight at inclusion ≥ 40 kg : 4 capsules of 1000 UI per day at induction and 2 capsules of 1000 UI per day at maintenance.
* Weight \< 40 kg: 2 capsules of 400 UI per day and 1 capsules of placebo at induction and 2 capsules of 400 UI per day at maintenance * Weight ≥ 40 kg: 2 capsules of 400 UI per day and 2 capsules of placebo at induction and 2 capsules of 400 UI per day at maintenance
Eligibility Criteria
You may qualify if:
- Age at randomization between 9 and 18 years inclusively
- Interval between diagnosis and randomization between 2 weeks and 6 months after the diagnosis
- Concurrent treatment with corticosteroids and/or enteral nutrition and/or thiopurines (azathioprine, 6-mercaptopurine) and/or methotrexate and/or 5-aminosalicylic acid (5-ASA) and/or TNF-α inhibitors (Infliximab, Adalimumab).
You may not qualify if:
- Patient diagnosed with severe complex perianal fistulizing CD (defined as the presence at diagnosis of a high intersphincteric, transsphincteric, extrasphincteric, or suprasphincteric complex perianal fistula)
- Known chronic liver cholestasis (defined by an elevation of conjugated bilirubin and/or gamma glutamyl transferase \> 3 upper limit normal)
- Known renal dysfunction requiring chronic dialysis or creatinine ≥ 100 micromol/L.
- Known congenital bone disease
- Known cystic fibrosis or other exocrine pancreatic insufficiency.
- Currently treated with anticonvulsants metabolized through cytochrome P-450
- Unable to take oral capsule form.
