About this study

Official title: Double-Blind Placebo Controlled, Cross-over Trial of Subcutaneous B12 on Behavioral and Metabolic Measures in Children With Autism.

We will be testing a specific dietary supplement, methylcobalamin (vitamin B12). Follow-up assessments with our clinical team will take place over the 12-week study period so that we can record any changes in development. The main goal of this study is to determine if subcutaneous injections of vitamin B12 given every three days can positively affect behavior and development in children with autism.

Hypothesis: Methylcobalamin injections will improve measures of executive function, speech, and socialization in children with autism, and will be associated with metabolic improvement.

Read the detailed description

Autism is a complex neurodevelopmental disorder that is thought to involve an interaction between multiple and variable susceptibility genes (Keller \& Persico, 2003), epigenetic effects (Beaudet, 2002), and environmental factors (London, 2000). The increase in the prevalence of autistic spectrum disorders from 4-5/10,000 in the 1980s to 30-60/10,000 in the last decade has raised great concern (Bertrand et al., 2001; DeStefano et al., 2004; Steinhausen et al., 1986; Yeargin-Allsopp et al., 2003). Research into potential therapeutic interventions designed to ameliorate the metabolic and clinical symptoms of autism is urgently needed to reduce the enormous public health burden of this disorder and to improve the quality of life for affected children and their families. Nutritional supplementation through subcutaneous injections of methyl B12 is a current treatment for children with autism that has anecdotal reports of remarkable clinical improvements and few side effects. However there are no published studies to support its clinical benefit.

Comparison: Injections of methylcobalamin compared to injections of sterile saline over a six week period.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • methylcobalaminDrug

    Also called Vitamin B-12, Methyl-B12

    Methylcobalamin (25,000μg/ml), at a dosage of 64.5μg/kg, or saline placebo administered subcutaneously, once every three days for six weeks. At six weeks, subjects cross over to the other treatment given every three days for another six weeks. Post 12 weeks, treatment with open label methylcobalamin will continue once every three days, for six months.

  • saline placeboOther

    Also called saline

    Methylcobalamin (25,000μg/ml), at a dosage of 64.5μg/kg, or saline placebo administered subcutaneously, once every three days for six weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing methylcobalamin in people with Autistic Disorder, run by University of California, San Francisco at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary measure is the Clinical Global Impression Scale -Improvement supplemented by videos taken at all visits and rated blindly to measure executive function, speech, and language, and socio-economic development. (time frame: 12 Weeks to 6 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00273650, which also lists 18 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Oct 2019.
