Autologous Cell Suspension Grafting Using ReCell in Vitiligo and Piebaldism Patients: a Randomized Controlled Study on the Recipient Site Preparation
In Brief
A Phase 4 clinical trial evaluating ReCell, Full surface CO2 laser 200 mJ, and 2 other interventions for Segmental Vitiligo and Piebaldism. Completed, enrolled 10 participants across 1 site.
Detailed Summary
The purpose of this study is to assess the efficacy and safety of ReCell grafting after CO2 laser abrasion with superficial full surface ablation, fractional laser treatment and conventional (deep) full surface CO2 laser ablation, to assess the practical aspects and the patient reported outcome and to assess the cellular composition of the graft.
Study Details
Timeline
Interventions
A split-thickness skin biopsy will be taken from the hip region of the patient. The skin biopsy that is obtained will be treated in the ReCell kit (Avita Medical Europe Ltd, Cambridge, UK): it will be placed in the heated enzyme solution, containing trypsin, in the device for 15-20 minutes to allow cell disaggregation. After that period, the biopsy will be taken from the enzyme solution and will be dipped in sodium lactate buffer solution. The biopsy will then be scraped to disaggregate the cells from the dermal epidermal junction. The epidermal cells are drawn up in a syringe. The prepared suspension will be dripped on both donor and acceptor site.
