About this study

Official title: The Effect of Vitamin D3 to Maintain Surgical Remission in Postoperative Crohn's Disease: a Placebo-controlled Randomized Trial

The majority of patients with Crohn's disease (CD) need to undergo surgical bowel resection. Postoperative recurrence of the disease is virtually inevitable and continues to be one of the most challenging therapeutic problems in inflammatory bowel diseases. Medical treatments to prevent recurrence have had limited effect. Anti-tumor necrosis factor (TNF) agents appear promising but are hampered by immunogenicity, side effects and high cost.

Vitamin D has recently received a lot of scientific attention and was found to have strong anti-inflammatory and antifibrotic effects in gut and liver inflammation. Many CD patients appear to have deficiency in Vitamin D. A controlled trial to prevent relapse of CD in medical (not surgical) remission suggested a preventive effect for Vitamin D but marginally missed its endpoint because of lack of power.

The ultimate proof of the anti-inflammatory effect of Vitamin D in CD can best be studied in the prevention of postoperative recurrence.

Read the detailed description

Our objective is to study the prophylactic effect of Vitamin D3 to prevent post-operative recurrence of Crohn's disease (CD), with an endoscopic endpoint 6 months after surgery as the primary outcome. Endoscopy has been an established surrogate marker for future clinical relapse. Secondary objectives include clinical recurrence rates at 6 months, the difference in recurrence rates among patients with and without low Vitamin D levels at baseline, the effects of Vitamin D3 on quality of life parameters, resource use and related costs.

ANTICIPATED OUTCOME This study will provide proof of the anti-inflammatory effect of vitamin D, which to our opinion can best be studied in a post-operative setting. Since post-operative recurrence is frequent, a safe and cost-effective therapy is highly needed for this indication. The hypothesis is that patients who receive vitamin D treatment will have less frequent and less severe endoscopic recurrence.

What is being measured

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

  1. Proportion of patients with clinically significant endoscopic recurrence at 6 months of vitamin D3 treatment postoperatively, defined as endoscopic Rutgeerts' score ≥i2.

    Measured: 0-6 months

Secondary outcomes (5)
  1. 1. Clinical CD recurrence measured with CDAI among the 2 groups at week 26 (CDAI ≥220)

    Measured: 0-6 months

  2. 2. NOD2 gene mutations: the difference in response to vitamin D treatment in patients NOD2+ versus patients NOD2-.

    Measured: 0-6 months

  3. 3. Difference in significant recurrence among all patients with low vitamin D at baseline

    Measured: 0-6 months

  4. 4. Quality of life, measured by one validated questionnaire for IBD patients (IBD-Q) and two general questionnaires (SF-36 and EuroQol)

    Measured: 0-6 months

  5. 5. Any adverse events

    Measured: 0-6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Vitamin D in people with Crohn's Disease, run by Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) at 1 site in Netherlands.

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 6 inclusion and 12 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 7 Dec 2017. 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 Netherlands. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Proportion of patients with clinically significant endoscopic recurrence at 6 months of vitamin D3 treatment postoperatively, defined as endoscopic Rutgeerts' score ≥i2. (time frame: 0-6 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 NCT02010762, which also lists 1 linked publication.

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 7 Dec 2017.
