The purpose of this study is to determine if topical ruxolitinib 1.5% will provide repigmentation in vitiligo lesions.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The hypothesis is that JAK inhibitors can also successfully treat vitiligo. Lesional skin of both alopecia areata and vitiligo primarily contain T cells in a TH1 response as opposed to a mixed cell infiltrate such as in psoriasis or lichen planus. Both alopecia areata and vitiligo are TH1 mediated diseases dependent on the production of IFN-gamma to drive the response. CD8+ T cells are both necessary and sufficient for melanocyte destruction in vitiligo (van den Boorn JG et al 2009) and CD8+NKG2D+ T cells are also necessary and sufficient for hair loss in alopecia areata (Gilhar A et al 2013).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percent Change in Vitiligo Area Severity Index (VASI) Score From Baseline to Week 20
Time Frame: Baseline to Week 20
The VASI for each body region (hands, upper extremities, trunk, lower extremities, feet) is determined by the product of the area involved in hand prints and the extent of depigmentation within each hand print unit measured patch (0-100). Area involved is measured by hand prints (1 hand print = 1%) with a possible range of 0-100. Degree of depigmentation is measured as: 1.00 (100%) = complete depigmentation, no pigment present, 0.90(90%)=specks of pigment present, 0.75(75%)=depigmented area exceeds the pigmented area, 0.50(50%)=pigmented and depigmented areas are equal, 0.25(25%)=pigmented area exceeds depigmented area, 0.10(10%)=only specks of depigmentation present, and 0.0(0%)=no depigmentation present.
Baseline to Week 20

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percent Change in Body Surface Area (BSA) of Repigmentation
Time Frame: Baseline and Week 20
Area involved is measured by hand prints (1 hand print = 1%) with a possible range of 0-100.
Baseline and Week 20
Number of Subjects Who Achieve a Physician Global Vitiligo Assessment (PGVA) of Clear or Almost Clear
Time Frame: Baseline and Week 20
Baseline and Week 20
Percent Change in Vitiligo European Task Force (VETF) Assessment - Body Surface Area
Time Frame: Baseline and Week 20
Vitiligo European Task Force assessment consisted of three components: Extent of disease reflecting the body surface area (0-100%), disease staging (0-20), and disease progression (-5 +5). Staging is based on cutaneous and hair pigmentation assessing the largest patch in each body area (head/neck, trunk, arms, legs, and hands/feet); Stage 0=normal pigmentation, Stage 1=incomplete pigmentation, Stage 2=complete depigmentation, Stage 3= partial hair whitening (<30%), Stage 4= complete hair whitening. Disease progression is based on assessing the largest patch in each body area; Score 0= similar limits, Score 1= progressive vitiligo (ongoing subclinical depigmentation), Score -1= regressive vitiligo (ongoing subclinical repigmentation). Where a higher number indicates more severe disease spread and a negative number indicates improving disease. These three subsets are evaluated and reported independently and not mutually related to each other.
Baseline and Week 20
Mean Dermatology Life Quality Index (DLQI) Scores
Time Frame: Baseline and Week 20
DLQI is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired. The percent change was calculated from the mean DLQI at baseline and week 20
