Interventions

  • Ruxolitinib Topical — DRUG
    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.
  • Placebo — DRUG
    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.

Study Details

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.

Arms

  • Experimental: Group treatment
    There will be 2 arms with intra individual comparison. 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 After 3 months, both sides will be treated by twice daily applications of topical ruxolitinib for 3 additional months.
  • Placebo Comparator: group placebo
    Each grafted side of the body will be randomly assigned to receive 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.
