Open Label Clinical Trial of Vitamin D in Children With Autism

October 8, 2019 updated by: University of California, San Francisco

Open Label Clinical Trial of Vitamin D Dosage Tolerability, and Effect on Behavioral Measures in Children With Autism

Primary: to investigate tolerability of interventional high dose Vitamin D3 supplementation, titrated to reach serum levels near the high end of the reference range (30-100 ng/ml), in vitamin D deficient pediatric Autism Spectrum Disorder (ASD) patients.

The study will determine if initial safety and effect estimates predict that a double blind randomized control trial (RCT) with a larger set of patients will be worthwhile in the localization of this treatment aimed at improving the symptoms of ASDs.

Exploratory: to determine efficacy of high dose D3 replacement for improvement in the core symptoms of autism, including sociability, eye contact, anger outbursts, stimming behavior, and sleep, as determined by parental and clinical evaluation scales.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical Global Impression Scale - Improvement (CGI-I)
Time Frame: Baseline and 12 weeks from Baseline
Assessment of global changes in severity of autistic symptoms. CGI-I scores formulated by the clinician based on parent interview of changes in the child's behavior and from direct clinical observation, where scores of 0 = no improvement,1 = minimally improved, 2 = much improved, and 3 = very much improved.
Baseline and 12 weeks from Baseline
