HREC ethics approval number 2023.216

Vitiligo causes white patches on your skin when the cells that provide colour to your skin are destroyed. Non-segmental Vitiligo affects both sides of the body, such as both knees and both hands.

The investigational drug for this study is Ritlecitinib and is given as an oral tablet. Ritlecitinib is a treatment for diseases of a similar nature to vitiligo, and has been well tolerated in previous clinical trials.

The purpose of this research project is to measure how safe and effective this medication is in treating participants with non-segmental vitiligo. Ritlecitinib selectively inhibits the body’s immune response. The outcome of this project could support new treatments to increase quality of life in people with non-segmental vitiligo.
