Clinical Trial Summary

The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is a randomized clinical trial in 25,871 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or fish oil (1 gram of omega-3 fatty acids) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study is being conducted among a sub-cohort of 771 participants in VITAL and will test the efficacy and safety of high-dose vitamin D supplementation vs. placebo on skeletal health and body composition.


Description:

The VITAL: Effects on Bone Structure and Architecture is an ancillary study of the parent VITAL. This study has enrolled a sub-cohort of 771 VITAL participants at the NIH-sponsored Harvard Catalyst Clinical and Translational Science Center (CTSC). The following measurements will be performed at baseline and 2 years post-randomization to determine whether high-dose vitamin D supplementation vs. placebo: 1) produces small increases or reduces bone loss in spine, hip, and total body areal bone density as assessed by dual x-ray absorptiometry (DXA); 2) reduces bone turnover as assessed by biomarkers of bone resorption and formation; 3) improves (a) volumetric bone mineral density (vBMD) and measures of bone structure as assessed by peripheral quantitative computed tomography (pQCT) and (b) bone microarchitecture as assessed by high resolution pQCT (HR-pQCT) at the distal radius and tibia as well as trabecular bone score (TBS) at the spine; and 4) results in changes in body composition as assessed by DXA. Parallel assessments of the effects of omega-3 fatty acids will be performed. This study may elucidate the mechanisms through which high-dose vitamin D may prevent age-related fractures and provide new insights into the role of vitamin D on skeletal health and body composition. We are currently analyzing the effects of daily dietary supplements of fish oil (1 gram of omega-3 fatty acids) vs. placebo on skeletal health and body composition.

Outcome

Type Measure Description Time frame Safety issue
Other Body Composition To determine whether vitamin D and/or omega-3 supplementation results in changes in body composition as assessed by DXA: total body fat and lean mass, and fat mass index and lean mass index, regional fat and lean mass and derived ratios. 2 years
Primary Change in Bone Density To determine whether vitamin D and/or omega-3 supplementation produces small increases or reduces bone loss in spine, hip, and total body areal bone density, as assessed by DXA. Reported values are rounded up. 2 years
Primary Bone Turnover P1NP To determine whether vitamin D and/or omega-3 supplementation reduces bone turnover, assessed biomarkers of bone formation (propeptide of type 1 collagen [P1NP]). 2 years
Primary Bone Turnover Beta Crosslaps To determine whether vitamin D and/or omega-3 supplementation reduces bone turnover, assessed biomarkers of bone resorption (beta crosslaps). 2 years
Secondary Change in Bone Structure To determine whether vitamin D and/or omega-3 supplementation results in changes in bone structure. 2 years
