NCT02186275

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.

    within 52 weeks after inclusion in the study

Secondary Outcomes (5)

  • the lapse of time from randomization to first relapse

    from randomization to first relapse

  • the number of relapses per patient per year

    within 52 weeks after randomization in the trial

  • the duration of corticotherapy

    between randomization and 52 weeks later

  • The number of CD related hospitalizations

    between randomization and 52 weeks later

  • The quality of life

    at 26 weeks and 52 weeks

Other Outcomes (2)

  • Change in the level of physical activities

    between randomization and 52 weeks later

  • Changes in bone mineral density

    between randomization and 52 weeks later

Study Arms (2)

Vitamin D3 3000 or 4000 UI/day then 2,000 UI/day

EXPERIMENTAL

3000 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)).

Drug: Vitamin D3: 3000 or 4000 UI/day then 2,000 UI/day

Vitamin D3 800 UI/day then 800 UI/day

ACTIVE COMPARATOR

800 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)).

Drug: Vitamin D3 800 UI/day then 800 UI/day

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.

Also known as: Cholecalciferol
Vitamin D3 3000 or 4000 UI/day then 2,000 UI/day

* 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

Also known as: Cholecalciferol
Vitamin D3 800 UI/day then 800 UI/day
