Combination Approach With Ritlecitinib and nbUVB Compared to Ritlecitinib Alone for Treating Vitiligo

Following central randomization, patients will be assigned to receive either ritlecitinib 100mg daily (QD) or a combined therapy using ritlecitinib 100mg QD + twice weekly narrowband UVB treatment for a duration of 52 weeks. At the end of this period, all participants will continue for the open-label phase, receiving ritlecitinib 100mg QD. Eligible participants will be stratified by Fitzpatrick Skin Type (FST, also known as phototype).
