About this study

Official title: Role of Vitamin D on the Relapse Rate of Multiple Sclerosis

Vitamin D3 supplementation reduces the incidence of multiple sclerosis.Although clinical cross-sectional studies have demonstrated vitamin D3 as a positive mediator in preventing relapses and disease progression, prospective randomized control trials are nevertheless necessary to confirm these statements and to determine the most efficacious, safe, and the minimum required doses. This hypothesis is going to be tested through a randomized triple blinded controlled trial in which after randomization, one group of patients will receive vitamin D and second group will receive placebo. Both groups are going to be followed in a similar way over a period of one year with follow ups at 4, 8 and 12 months. Vitamin D levels is going to be performed at 0,4, 12 month interval. MRI is going to be done at the beginning and end of trial.The number of relapses and the physical disability will be calculated through the Expanded disability status scale (EDSS).

Read the detailed description

Study Objectives:

  • To estimate the prevalence of vitamin D deficiency in Saudi Multiple Sclerosis(MS) patient coming to King Khalid hospital, multiple sclerosis clinic.
  • To compare the difference in the relapse rate among Multiple Sclerosis patients who are taking vitamin D3 (50,000 IU per week) versus those who are not taking Vitamin D3 supplements.
  • To assess and compare the improvement in the Expanded Disability Status scale and clinical symptoms among those who are taking vitamin D3 versus those who are on placebo

Study Design: A single centre, triple-blinded, parallel randomized placebo controlled trial.

Methods: All eligible patients with clinical definite MS will be assigned a computer-generated Identification number by the statistician and through randomization divided into two groups, one group receiving vitamin D3 (the intervention arm) and other getting placebo (the control arm). All patients will continue with their routine pre-intervention trial treatment for relapse and remission phases of multiple sclerosis. The first treatment group will receive 50,000 IU units of vitamin D3 per week . The control arm patients, instead of vitamin D3 will receive a placebo supplement that looks, smells and tastes the same as the vitamin D3 for 52 weeks. Compliance with the study treatment will be verified by asking the patients about missed doses and by counting used and unused bottles.

All patients will be asked questions related socio-demographic data, vitamin D related dietary products, physical activity questions, exposure to sunlight and variation according to season, use of sunscreen, body coverage when in sunlight and any previous treatment for Multiple Sclerosis, including any vitamin D supplements. Every follow up visit shall include documentation of complete neurologic and medical history and findings. This will be a triple-blinded trial. The patient, the treating physician and the statistician will be masked to the type of treatment each patient receives.Sealed envelopes containing the vitamin D3 or placebo are going to be handed over to the physician with the computer assigned number of the patient. At each follow-up visit all patients will be required to bring their envelopes along with empty/ filled bottles to assess their compliance with the treatment.

The treating physician will follow all the patients at set regular intervals: 0 (baseline), 4, 8, and 12 months to assess the relapses and the EDSS scores and also to check for any adverse effects arising because of the vitamin D3 supplements. Patients who are going to miss their appointment shall be contacted by the project staff to set another appointment in the subsequent week. All patients are going to be emphasized about the importance of these clinical visits and their compliance with the treatment. All patients will be evaluated by the same treating physician.

The record says: status not confirmed, as of the sponsor's last update on 20 Dec 2012. 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 Saudi Arabia. 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 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.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Prof. Abdulkader Daif, M.D (0966-0504205164, adaif@ksu.edu.sa), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Relapse rate in patients with Multiple Sclerosis (time frame: 12 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 NCT01753375, which also lists 7 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 20 Dec 2012.
