Trial summary

Vitamin D likely plays a role in the geography of Multiple Sclerosis (MS), and patients at risk and with MS have relatively low Vitamin D levels compared to their normal counterparts. This trial examines the safety of high dose oral Vitamin D3 titrated up to a maximum of 40,000 IU per day over a 12 month period. Read more about this study

About this study

Official title: A Phase I/II Dose-Escalation Trial of Vitamin D3 With Calcium Supplementation in Patients With Multiple Sclerosis

Vitamin D likely plays a role in the geography of Multiple Sclerosis (MS), and patients at risk and with MS have relatively low Vitamin D levels compared to their normal counterparts.

This trial examines the safety of high dose oral Vitamin D3 titrated up to a maximum of 40,000 IU per day over a 12 month period. Fifty patients matched for MS and non-MS characteristics will be divided into two groups: one group receiving the high dose Vitamin D regimen, and the other restricted to a maximum of 4000 IU per day. The hypothesis is that patients with MS can tolerate seemingly high doses of Vitamin D3 without adverse events and/or calcium-related abnormalities. It is also hypothesized that those receiving the higher doses will demonstrate improved relapse and disability status compared to controls, and that the treatment group will show improved markers of bone health and immune indicators of reduced inflammation.

TreatmentExperimentalStarting dose of 4,000 IU per day of Vitamin D3 titrating up to a dose of 40,000 IU per day of Vitamin D3 by month six. In the second six-month part of the trial, patients titrate back down to 4,000 IU per day of Vitamin D3 and then discontinue it completely at the end of the 12 month trial period.
Receives: Dietary Supplement: Vitamin D3
ControlOtherPatients are allowed to supplement with up to 4,000 IU per day of Vitamin D3 if desired.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Vitamin D3 in people with Multiple Sclerosis, run by University of Toronto at 1 site in Canada.

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 3 inclusion and 8 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 28 Mar 2008. 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 Canada. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

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?

Serum calcium (time frame: at each dose change). 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 NCT00644904, which also lists 3 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 28 Mar 2008.
