An interventional study of vitamin D3 in Vitamin D Deficiency, sponsored by University of British Columbia. Status unknown at 1 site in Canada. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2018-05-23.
Sponsored by University of British Columbia · Not applicable, Interventional, and Prevention
This study is to assess whether a single oral loading dose of 100,000 IU vitamin D3 prior to allogeneic hematopoietic stem cell transplant (aHSCT) can achieve optimal 25 hydroxy-vitamin D3(25-OH-D3) levels (>75nmol/L) at one month post aHSCT, and maintain adequate levels for at least three months, compared to our standard practice of 2000 IU vitamin D3 daily. 25-OH-D3 levels will be measured prior to vitamin D3 supplementation, and 30 as well as 100 days post vitamin D supplementation. We hypothesize that the intervention will prevent vitamin D insufficiency or deficiency in aHSCT recipients, therefore benefit aHSCT-associated morbidity, including osteoporosis.
This is a randomized non-blinded single centre prospective clinical trial designed to validate whether a single oral loading dose of 100,000 IU vitamin D3 prior to allogeneic hematopoietic stem cell transplant (aHSCT) can achieve optimal 25 hydroxy-vitamin D3(25-OH-D3) levels (>75nmol/L) at one month post aHSCT, and maintain adequate levels for at least three months, compared to our standard practice of 2000 IU vitamin D3 daily.
84 patients will be enrolled. Following completion of all baseline data collection, participants will be randomized 1:1 to the intervention group or the control group on the admission day for aHSCT
Patients in the intervention group will receive a single oral loading dose of 100,000 IU vitamin D3, with subsequent vitamin D3 2000 IU daily. Patients assigned to the control group will receive our current standard of care, 2000 IU vitamin D3 daily.
772 studies on the registry are indexed under Vitamin D Deficiency; 61 are open to participants now.
This study's planned enrollment of 84 is close to the median of 77 across 564 interventional studies indexed under Vitamin D Deficiency.

Exclusion Criteria:
Participants assigned to the intervention group will receive a single oral loading dose of 100,000 IU vitamin D3 on the day of hospital admission for aHSCT, with subsequent vitamin D3 2000 IU daily.
Dietary Supplement: vitamin D3
Participants assigned to the control group will be advised to take our current vitamin D regimen (2000 IU vitamin D3 daily).
a single oral loading dose of 100,000 IU vitamin D3 on the day of hospital admission for aHSCT, then 2000 IU vitamin D3 daily.
To assess the efficacy of 100,000 IU vitamin D3 prior to aHSCT
To assess the efficacy (the proportion of patients achieving sufficient serum 25-OH-D3 level) after a single oral loading dose of 100,000 IU vitamin D3 prior to aHSCT, with subsequent vitamin D3 2000 IU daily, in preventing vitamin D insufficiency/deficiency in the first 100 days post-aHSCT.
