Conditions rheumatoid arthritis, vitamin d deficiency
Treatments placebo sugar pill, ergocalciferol
Sponsor Johns Hopkins University
Start date January 2009
End date December 2011
Trial size 140 participants
Trial identifier NCT01426347, VDRA


The purpose of this study is to investigate the effect of vitamin D repletion on disease activity and disability in patients with rheumatoid arthritis.

The investigators hypothesize that rheumatoid arthritis (RA) patients with vitamin D deficiency have greater disease activity and disability, compared to RA patients with normal vitamin D levels. The investigators also hypothesize that vitamin D treatment in these deficient patients will result in a decrease in RA disease activity and disability.

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking double blind (subject, investigator, outcomes assessor)
Primary purpose treatment
(Placebo Comparator)
RA Patients with vitamin D deficiency will be randomized to placebo and active intervention arms. Patients in the placebo arm will receive I placebo pill per week for 16 weeks. After completing this arm, they will cross-over to the active treatment arm.
placebo sugar pill Placebo
Intervention includes 1 sugar pill once a week for 16 weeks dispensed as a capsule.
(Active Comparator)
Patients with vitamin D deficiency will be randomized to either active or placebo group. In the active group, patients will receive ergocalciferol 50,000 IU per week for 16 weeks.
ergocalciferol Vitamin D
Ergocalciferol 50,000 IU per week for 16 weeks
