Vitamin D Levels Following Topical Application of Vitamin D Ointment (VITD-001)

Vitamin D Levels in Subjects With Vitamin D Deficiency Following Topical Application of Three Doses of Vitamin D Ointment - A Proof of Concept Study

This is a pre-post open label trial to assess the change in Vitamin D blood levels following treatment with three doses of topical Vitamin D3 in subjects with existing Vitamin D deficiency.

Study Overview

• Status: Completed
• Conditions: Vitamin D Deficiency
• Intervention / Treatment: Drug: Dose 1; Drug: Dose 2

Detailed Description

The proposed study investigates safety and efficacy of a new topical vitamin D3 compound. The purpose of this Phase 1 trial is to determine whether topical application makes Vitamin D bioavailable to the systemic circulation in sufficient quantities to treat hypovitaminosis D. The study will assess the change in serum 25-hydroxy (25-OH) vitamin D concentrations following 3 doses of 100,000 IU or 3 doses of 300,000 IU of topical vitamin D3 ointment in volunteers with vitamin D deficiency. Adults with serum 25-OH vitamin D concentrations of < 20 ng/ml will receive a total of 300,000 IU or 900,000 IU in divided doses of topical vitamin D once per week for three weeks. Two 0.75 ml applicators of ointment will be applied to each upper arm (50,000 IU or 150,000 IU per arm) by study staff. Blood will be drawn at baseline prior to the first dose (Day 0) and on Days 7, 14, and 21. Total serum 25-OH vitamin D will be assayed at each draw. Parathyroid hormone, a measure of clinical effects of low vitamin D levels, will be checked at baseline and on day 21. Serum albumin adjusted calcium levels will be checked with each draw to check for possible effects of too much vitamin D absorption. The study will determine whether the topical application of Vitamin D ointment is able to correct existing vitamin D deficiency.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Dose 1; Three topical applications of 100,000 units for a total of 300,000 units of vitamin D3 in a newly formulated ointment will be applied to the upper arms over three weeks.

Vitamin D levels will be checked on days 7, 14, and 21.; Other Names: cholecalciferol; 25-OH Vitamin D
Experimental: Dose 2; Three topical applications of 300,000 units for a total of 900,000 units of vitamin D3 in a newly formulated ointment will be applied to the upper arms over three weeks.	Drug: Dose 2; Subjects with vitamin D deficiency will be given 300,000 units of topical vitamin D on days 0,7, and 14. Vitamin D levels will be checked on days 7, 14, and 21.; Other Names: cholecalciferol
