Promoting Repigmentation After Epidermal Cell Suspension Grafting and preVENTing the Loss of Melanocytes Using Topical Ruxolitinib for Vitiligo in Resistant Areas. Prospective Monocentric Interventional Study With Blinded Evaluation

Medical approaches remain the gold standard treatment for non-segmental forms of vitiligo. Topical ruxolitinib cream has demonstrated its efficacy and good tolerance for treating vitiligo. While about 30% of patients will achieve at least 90% of repigmentation on the face after 1 year of treatment, some locations on the body, such as hands, feet, bony prominences remain highly challenging, and most patients won't get satisfactory repigmentation on those areas despite months of application of topical treatments, even when combined with UV. The poor rate of repigmentation in these locations are probably explained by the difficulty to stimulate the differentiation and proliferation of melanocytes stem cells in those areas. To study the efficacy at 3 months of epidermal cell suspension grafting followed by twice daily applications topical 1.5% ruxolitinib cream compared to epidermal cell suspension grafting followed by placebo in vitiligo resistant areas.There will be 2 arms with intra individual comparison. Both groups will receive epidermal cell suspension (provided by Cutiss®). After 7 days the dressing will be removed. Each grafted side of the body will be randomly assigned to receive twice daily application of topical 1.5% ruxolitinib cream (Group A) or twice daily application of placebo cream (Group B). After 3 months, both sides will be treated by twice daily applications of topical ruxolitinib for 3 additional months.There will be 8 visits in total during the 7 months duration for each subject.

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.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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
Repigmentation of the target area
Time Frame: At three months and visit inclusion.
The primary objective will be assessed using the depigmentation of the target lesion. A drawing of the target lesions will be done at V1 (week 0), V5 (week 12) and V6 (wk24). Repigmentation of the target area will be calculated using Image J software in order to have an objective measurement of the response. We will define success as a repigmentation ≥50%, repigmentation being define as the difference of depigmentation between M3 and M0.
At three months and visit inclusion.
