NCT05872477 | COMPLETED | Vitiligo

Promoting Repigmentation After Epidermal Cell Suspension Grafting and preVENTing the Loss of Melanocytes Using Topical Ruxolitinib for Vitiligo in Resistant Areas
Sponsor:

Nice University Hospital Center

Brief Summary:

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.

  • 10. Allergy to ruxolitinib cream, xylocaine or hyaluronic acid or trypsin (Viticell® must not be utilised with patients who are hypersensitive to hyaluronic acid or trypsin)
  • 11. Active infection
  • 12. Patients with thromboembolic risk

  • 16. Participants with active acute bacterial, fungal, or viral skin infection within 1 week before baseline;
  • 17. Participants with concurrent malignant disease or a history of that in the 5 years preceding the baseline visit except for adequately treated non metastatic malignancies;
  • 18. Participants with current and/or history of liver disease, including known hepatitis B or C, with hepatic or biliary abnormalities;
  • 19. Participants with current and/or history of tuberculosis;
  • 20. Participants who have used depigmentation treatments for past treatment of vitiligo or other pigmented areas.
