About this study

Official title: Combined Therapy With NB-UVB Phototherapy and Oral Vitamin D Supplementation in Patients With Vitiligo: a Randomized-clinical Trial, Triple-blind, Placebo-controlled

A randomized clinical trial that treats vitiligo patients with oral vitamin D and Narrow-Band Ultraviolet B (NB-UVB) phototherapy (intervention group); or placebo and NB-UVB phototherapy (control group). We will evaluate if the group supplemented with vitamin D achieves a higher repigmentation rate than the control group, proving the relevance of vitamin D as an immunomodulator in the pathophysiology of vitiligo. These findings may support the use of vitamin D as an economic, safe, and adjuvant treatment for vitiligo.

Read the detailed description

A randomized clinical trial, triple-blind, placebo-controlled treating patients with diagnosed vitiligo. The intervention group will be treated with oral vitamin D 5,000 IU per day and NB-UVB phototherapy. The control group will be treated with placebo and NB-UVB phototherapy. We will evaluate the efficacy (repigmentation rate) and improvement of the quality of life with vitamin D and phototherapy versus placebo and phototherapy.

Our objectives are:

  • Evaluate if the use of the supplementation with oral vitamin D accelerates the repigmentation rate in vitiligo lesions treated with NB-UVB phototherapy, achieving a lower accumulated dose of phototherapy.
  • Compare basal blood levels of vitamin D before and after treatment completion.
  • Compare quality of life of the intervention group with the control group.
  • Associate pigmentation rates between intervention and control group obtained with tools that assess activity of disease, such as, Vitiligo Area and Severity Index (VASI) and Vitiligo European Task Force (VETF) score.
  • Compare results in quality of life between intervention and control group obtained with tools, such as, Vitiligo-Specific Quality-of-Life Instrument (VitiQoL) and Dermatology Life Quality Index (DLQI).

What is being measured

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

  1. VASI score - Vitiligo Area and Severity Index (VASI)

    The VASI score is used to assess the severity and extent of Vitiligo. VASI is calculated using a formula that includes contributions from all body regions (possible range, 0-100). The body is divided into 6 separate and mutually exclusive sites (head/neck, hands, upper extremities [excluding hands], trunk, lower extremities [excluding feet], and feet), with percentage of vitiligo involvement estimated in hand units by the same investigator throughout the study.

    Measured: Week 0

  2. VASI score - Vitiligo Area and Severity Index (VASI)

    The VASI score is used to assess the severity and extent of Vitiligo. VASI is calculated using a formula that includes contributions from all body regions (possible range, 0-100). The body is divided into 6 separate and mutually exclusive sites (head/neck, hands, upper extremities [excluding hands], trunk, lower extremities [excluding feet], and feet), with percentage of vitiligo involvement estimated in hand units by the same investigator throughout the study.

    Measured: Week 12

  3. VASI score - Vitiligo Area and Severity Index (VASI)

    The VASI score is used to assess the severity and extent of Vitiligo. VASI is calculated using a formula that includes contributions from all body regions (possible range, 0-100). The body is divided into 6 separate and mutually exclusive sites (head/neck, hands, upper extremities [excluding hands], trunk, lower extremities [excluding feet], and feet), with percentage of vitiligo involvement estimated in hand units by the same investigator throughout the study.

    Measured: Week 24

Secondary outcomes (10)
  1. VETF score - Vitiligo European Task Force (VETF) score

    The VETF is a validated scoring system that assesses 3 dimensions of the disease (extent, staging, and spreading/progression). (1) the extent of vitiligo will be estimated as the percentage of vitiligo involvement of 5 body sites. (2) Stage of vitiligo will be assessed as 0 (normal pigmentation), 1 (incomplete depigmentation), 2 (complete depigmentation), 3 (partial hair whitening [<30%]), and 4 (complete hair whitening). (3) Spreading of vitiligo will be scored as 0 (stable disease), -1 (observed ongoing subclinical repigmentation), and +1 (additional patches in a given area or observed ongoing subclinical depigmentation). The VETF score calculated as follows:

    VETF Extent or Staging or Spreading = Sum of all specific values for that category from all body sites (% of Area affected for Extent; 0-20 for Staging; -5 to +5 for Spreading).

    Measured: Week 0

Questions about this trial

What is this clinical trial studying?

A study testing Oral Vitamin D and NB-UVB Phototherapy in people with Vitiligo and Vitiligo, Generalized, run by Hospital Universitario Dr. Jose E. Gonzalez at 1 site in Mexico.

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 10 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 Feb 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 Mexico. 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.

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?

VASI score - Vitiligo Area and Severity Index (VASI) (time frame: Week 0). The study lists 3 primary outcomes in all. 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 Feb 2023.
