Vitamin D Deficiency Clinical Trial
Official title:
Evaluation of a Transdermal Vitamin D3 Delivery System, D3forME
A clinical need exists for non-oral vitamin D administration. This study is designed to test a new proprietary transdermal system. It is looking to see if this new system will safely and successfully deliver vitamin D3 to humans.
This will be conducted in 3 stages. The hypotheses of this work are as follows:
1. The D3forME topical supplement patch will effectively and safely raise serum 25(OH)D3 in
humans.
2. The 25(OH)D3 increment with a daily 4,000 IU D3forME topical supplement patch will be
superior to a placebo patch.
3. The 25(OH)D3 increment with a daily 4,000 IU D3forME topical supplement patch will be
non-inferior to that achieved with 4,000 IU of oral vitamin D3 daily.
4. The 25(OH)D3 increase achieved with the D3forME topical supplement patch will not differ
between young and older adults.
To test these hypotheses, this research will be conducted in three stages:
Stage 1: Open Label Proof of Concept Pilot Study. This study will document safety and
tolerability of daily D3forME topical supplement patches containing 4,000 IU of vitamin D3 in
15 healthy adult men and women.
The specific aims of this study are to:
1. Document the change in serum 25(OH)D3 with daily transdermal vitamin D3 dosing of 4,000
IU using the D3forME topical supplement patch.
2. Evaluate safety and skin tolerability of the D3forME topical supplement patch.
Stage 2: Efficacy study. In this randomized, double blind placebo controlled study of four
months duration involving 40 healthy adult men and women (n = 20 per group) the specific aims
are to:
1. Evaluate the safety and efficacy of daily D3forME topical supplement patches to increase
serum 25(OH)D3.
2. Determine if the 25(OH)D3 increase achieved by 4,000 IU of daily D3forME topical
supplement patches is superior to placebo.
Stage 3: Non-inferiority study. In this randomized, double blind placebo controlled study of
six months duration involving 220 healthy adult men and women in two age cohorts, (18-40
years and 65-85 years), the specific aims are to:
1. Determine if the 25(OH)D3 increase achieved by 4,000 IU of daily D3forME topical
supplement patches is not inferior to that achieved by 4,000 IU oral vitamin D3
supplementation.
2. Assess if the 25(OH)D3 increase achieved by daily D3forME topical supplement patches
differs between young and old adults.
As an exploratory endpoint, the potential effect of body fat on response to daily D3forME
topical supplement patches will be evaluated using DXA to measure body composition in the
efficacy and non-inferiority studies (stages 2 and 3 above).
Open-label Proof of Concept Pilot Study. This open label study will evaluate the safety of a
once daily D3forME topical supplement patches containing 4,000 IU of vitamin D3.
Additionally, it will begin evaluating the efficacy of this approach on serum 25(OH)D3. This
pilot study will include 15 healthy community dwelling men and women age 18-75 years without
conditions contraindicating D supplementation or known skin conditions that could potentially
interfere with cutaneous vitamin D3 delivery. Volunteers will be recruited from the Madison,
WI area.
Stage 2: Randomized Double-blind, Placebo Controlled Efficacy Study: This study will include
40 adults (n = 20 in each group) using the same inclusion/exclusion criteria
Stage 3: Non-inferiority Study: This phase will include 220 adults randomly assigned to one
of three treatment arms: n = 100 transdermal patch/placebo oral, n = 100 oral
supplementation/placebo patch and n = 20 placebo oral and placebo patch) using the same
inclusion/exclusion criteria as the noted above, except for age, which will be limited to
18-40 and 65-85. Additionally, each treatment arm will be equally divided into two cohorts,
"young;" age 18-40 and "old;" age 65-85 years.
