Evaluation of Non-cultured Epidermal Cellular Grafting vs Hyaluronic Acid for Repigmenting Vitiligo and Piebaldism

A Multicenter Double-blind Placebo-controlled Trial of Non-cultured Epidermal Cellular Grafting Versus Hyaluronic Acid for Repigmenting Stable Leukoderma (Vitiligo and Piebaldism)

The purpose of this study is to assess the efficacy of autologous epidermal cells suspension grafting using a newly developed device named VITICELL® compared to placebo.

The secondary objective is to evaluate safety of VITICELL® and global satisfaction of patient and investigator.

Inclusion Criteria:

• Men and women aged over 18 years old with a diagnosis of non-scaring leukoderma that has been stable over the last 2 years (non-segmental, segmental vitiligo and piebaldism)
• For non-segmental vitiligo: symmetrical vitiligo lesions, or parts of a lesion. A part of at least 1 cm2 (1 x 1 cm), but preferable 4 cm2 (2x2 cm) and preferably in the center of each lesions (left/right) should be treated.

The minimum distance between the normal pigmented skin and the test area should preferably be at least 0.5 cm.

• For segmental vitiligo lesion and piebaldism: all lesions possible if two parts of at least 1 cm2 (1 x 1 cm), but preferably 4 cm2 (2 x 2 cm) in the lesion can be treated. The minimum distance between the 2 areas should be 2 cm and between test areas and to the normal pigmented skin preferably at least 0.5 cm.
• Medical treatments of vitiligo failed (in case of vitiligo: at least cream treatment for 6 months).
• Absence of infected lesion
• Negative serology (HIV-hepatitis B and C- Syphilis)
• Without treatment one month for cream and 3 months for phototherapy

Exclusion Criteria:

• Hypersensibility to local anaesthetics or one of the components of the device (trypsin, hyaluronic acid)
• Indication against biopsies
• Patient with a history of melanoma
• Positive serology (ongoing serious systemic disease, herpes, HIV, hepatitis B and C-Syphilis)
• Positive pregnancy test
• History of keloidal scars and presence of Koebner's phenomenon (type 1 and type 2b)
• Infected lesion
• Test areas not on fingers and toes vitiligo areas in case of non-segmental vitiligo
• Test areas not on facial non segmental vitiligo
• Pregnant women, or lactating
• Age <18years
• Major deprived of their freedom by administrative or legal decision, or being the subject of a legal protection measure, or out of state to express their consent
