Trial Summary

What is the purpose of this trial?

This trial tests a new treatment for people with stable vitiligo, a condition where patches of skin lose their color. The treatment uses the RECELL Device to create a mixture of the patient's own skin cells, which is then applied to the discolored areas. Patients also use a special light therapy at home to help improve the results.

Will I have to stop taking my current medications?

The trial requires that you stay on any current immunosuppressive therapy for the duration of the study. However, if you are taking medications like anticoagulants, you may need to stop if the investigator thinks they could affect your safety or the study's goals.

What data supports the effectiveness of the treatment RECELL® Autologous Cell Harvesting Device for vitiligo?

Research shows that the RECELL system, used for stable vitiligo, can be effective in repigmentation, as it involves harvesting skin cells that help restore color to affected areas. Similar techniques, like epidermal skin grafting, have been shown to be safe and effective in improving the appearance of vitiligo.12345

Is the spray-on skin cell treatment safe for humans?

The spray-on skin cell treatment, also known as the ReCell system, has been shown to be safe in studies for treating stable vitiligo. It is a simple and safe technique with low rates of complications, and it does not require complex laboratory facilities.12567

How does the RECELL® Autologous Cell Harvesting Device treatment for vitiligo differ from other treatments?

The RECELL® Autologous Cell Harvesting Device is unique because it involves spraying a suspension of a patient's own skin cells onto the affected area, which can accelerate repigmentation without the need for painful surgical procedures or local anesthesia, unlike traditional skin grafting methods.1891011

Eligibility Criteria

This trial is for adults with stable vitiligo, which hasn't changed in the past year. They should have tried topical therapy or phototherapy without success and be willing to stick to their current immunosuppressive drugs and at-home phototherapy during the study. Participants must not use other treatments or join another trial for 24 weeks.
