A Pilot Study of Vitamin D in Boys With X-linked Adrenoleukodystrophy
Not Recruiting
Trial ID: NCT02595489
Purpose
In this pilot study, the investigators will assess the safety of two high-dose regimens of
oral vitamin D supplementation and measure the effects of vitamin D supplementation on
markers of oxidative stress and inflammation in the blood and brain of study participants
before, during, and after taking vitamin D supplements.
The goal of the study is to establish research measures (i.e. biomarkers) and an optimal dose
for vitamin D supplementation in boys with the X-linked adrenoleukodystrophy (ALD) genotype.
