About this study

Official title: The Reflection of Skin Color on the Efficacy of Narrow Band UVB in Stabilization of Active Cases of Vitiligo

Vitiligo is a disease in which autoimmunity plays a major role. Multiple treatment options are available, of which narrow-band UVB is a cornerstone, acting through immunosuppression and repigmentation by stimulating reservoir melanocytes.

It's expected that this immunsupression is lower in darker skin types, where increased basal melanin might act as a barrier.

Read the detailed description

Vitiligo is acquired depigmentation disorder. Several theories were hypothesized for causing vitiligo, of which the autoimmune theory is the most accepted.

The main targets of therapy are stabilization of the disease activity through immunosuppression, and repigmentation through stimulation of reservoir melanocytes proliferation and migration.

Narrow band ultraviolet phototherapy (NB-UVB) remains the cornerstone treatment of vitiligo. NB-UVB can induce both immunosuppression and repigmentation. Several factors can modulate the efficacy of NB-UVB therapy in treatment of vitiligo cases, including patient's age, lesion site, duration of the disease, and duration of the therapy.

The immunosuppressive function of NB-UVB was first detected in 1963 by Hanisko and Suskind, who observed that the contact hypersensitivity response in skin sensitized to dinitrochlorobenzene (DNCB) was reduced if skin was previously exposed to suberythemal doses of UVB.

Present evidence suggests that UVB suppress immune system through generation of T-suppressor cells, which inhibit the effector cells of Th1 type. It appears that UV-induced immunosuppression depresses the function of Th1 cells and enhances the activity of Th2 cells via cytokines such as Interleukin 10.

It's expected that this immunsupression is lower in darker skin types, where increased basal melanin might act as a barrier. However, skin was previously divided to UVB-resistant and UVB-sensitive (UVB-R and UVB-S) based on the contact hypersensitivity testing, regardless of the skin type. Moreover, A study on NB-UVB phototherapy for psoriasis revealed that photoadaptation during NB-UVB therapy Is Independent of skin type.

What participants receive

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

  • Oral dexamethasone minipulseDrug

    Also called Narrow band UVB

    50 patients will receive mini pulse dexamethasone therapy in a dose of 3 mg/ day for adults or 1.5 mg/day for children on two consecutive days per week plus NB-UVB phototherapy at starting dose of 0.3 J/cm2, at a rate of 3 times per week for 6 months (72 sessions) with gradually increasing increments.

  • Placebo oral tabletDrug

    Also called Narrow band UVB

    50 patients will receive placebo having the same color, form and packaging as the dexamethasone therapy for 6 months plus NB-UVB phototherapy at starting dose of 0.3 J/cm2, at a rate of 3 times per week for 6 months (72 sessions) with gradually increasing increments

What is being measured

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

  1. Detecting number of participants with clinical activity of vitiligo

    Appearance of new lesions or expansion of pre-existing lesions by clinical examination.

    Measured: At 6 months after treatment.

  2. Photography to detect activity of vitiligo

    New lesions in each area will be counted.

    Measured: Change from baseline (first visit) at 6 months after treatment.

  3. Elevation of serum Vitiligo activity markers.

    A 5 cc blood sample will be withdrawn from each patient for:

    ELISA assessment of CXCL-10 (Pg/ml)

    Measured: Change from baseline at 6 months after treatment.

  4. Elevation of PCR levels of serum Vitiligo activity markers

    A 5 cc blood sample will be withdrawn from each patient for:

    PCR assessment of m-RNA of CXCL-10 as markers of disease activity.

    Measured: Change from baseline at 6 months after treatment.

Model description
100 patients with non-segmental vitiligo are randomized to either NB-UVB therapy with placebo versus NB-UVB combined with mini-oral pulse steroids therapy. Vitligo activity will be assessed according to the VIDA scoring system. Skin type, extent of vitiligo using VES score, photography of all areas according to the VES areas at a fixed distance of 50 cm from the patient, and using a 1 cm diameter circular white sticker for reference later will be done. All patients will receive NB-UVB phototherapy at starting dose of 0.3 J/cm2, 3 times per week for 6 months (72 sessions) with gradually increasing increments according until faint erythema is attained at which point the dose is fixed. 100 patients will be randomized into 2 groups; 50 patients will receive mini pulse dexamethasone therapy in a dose of 3 mg/ day for adults or 1.5 mg/day for children on two consecutive days per week while the other 50 patients will receive placebo having the same color, form and packaging for 6 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Oral dexamethasone minipulse in people with Vitiligo, run by Ain Shams University at 1 site in Egypt.

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 4 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: status not confirmed, as of the sponsor's last update on 24 Jul 2019. 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 Egypt. 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 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.

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

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

Contact Mahy ElBassiouny, Ass.Lecturer (002 01002202651, mahyelbasyouni@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Detecting number of participants with clinical activity of vitiligo (time frame: At 6 months after treatment.). The study lists 4 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.
