About this study

Official title: A Local Interventional Study in a Cohort of Patients With GPA, MPA and EGPA (PART 2 of "Vitamin D Status in ANCA-associated Vasculitis: Analysis of RDCRN-VCRC and Local Clinic Cohorts of Patients With GPA, MPA and EGPA")

This prospective study will assess if 12 months of vitamin D3 (cholecalciferol) supplementation, in patients with AAV (GPA, MPA, and EGPA) who have deficient or insufficient 25(OH)D3 status at enrollment, correlates with improved disease activity and/or lower frequency of relapse (compared to historical data and a previously conducted cross sectional study (part I) that assessed vitamin D status in a cohort of similar patients).

Read the detailed description
  1. Subject cohorts: Patients with a diagnosis of AAV from the MSH Rheumatology clinic in a cohort of consecutive patients over a 3 month recruitment period.
  2. Study Design, Data Collection: Patients with insufficient and/or deficient vitamin D status at study enrolment will be instructed to take 12 months of vitamin D3 (cholecalciferol) supplementation (1000 IU for those not on vitamin D, or to increase the dose up to 2000 IU per day for those already on vitamin D) vs. those with sufficient status who will be observed for 12-months.
  3. Study Duration: 12 months.
  4. Study Endpoints: Vitamin D status vs. disease activity.

What participants receive

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

  • vitamin DDietary supplement

    Patients with insufficient and/or deficient vitamin D status (<75 nmol/L) at study enrolment will be instructed to take a 12-month supply of vitamin D3 supplementation (to a maximum of 2,000 IU/day) vs. those with sufficient status will be observed for 12-months

Study groups in NCT04280601
Study groupRoleWhat they receive
Low vitamin level at baselineOtherAt specific time points we will measure vitamin D status (baseline and 12-months) and re-enforcing vitamin D supplementation in those with insufficient or deficient vitamin D levels. More specifically, we will ask patients with insufficient or deficient vitamin D levels at enrollment to increase vitamin D intake by 1,000 IU units (to a maximum of 2,000 IU if the patient is already on vitamin D supplementation) for the 12 month period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Disease activity and disease relapse (using BVAS)

    Number of patients with active disease (BVAS score) or disease relapse (new item on the BVAS, in patients previously in remission) between enrollment and month 12, according to the study arm intervention (normal baseline vitamin D level vs. low baseline level and asked to increase vitamin D intake)

    Measured: 12 months

Secondary outcomes (4)
  1. Renal function (GFR)

    Number of patients with progressive renal AAV-related disease (worsening GFR) in each study arm between enrollments and month 12

    Measured: 12 Months

  2. Cardiovascular events

    Number of patients with cardiovascular events (IM, stroke) in each study arm between enrollments and month 12

    Measured: 12 Months

  3. Interstitial lung disease diagnosis or progression (imaging and PFT)

    Number of patients with new diagnosis of ILD or worsening of ILD in each study arm (based on clinical, and either imaging and/or PFT findings) between enrollments and month 12

    Measured: 12 Months

  4. Glucocorticoid use (and cumulative dose, mg)

    Use of glucocorticoids (including cumulative dose) in each study arm between enrollment and month 12

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing vitamin D in people with ANCA-associated Vasculitis and Granulomatosis With Polyangiitis, run by Christian Pagnoux 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 3 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 14 Mar 2023. 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.

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?

Disease activity and disease relapse (using BVAS) (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 14 Mar 2023.
