This clinical trial is focused on studying the effects of a treatment for vitiligo, a condition that causes patches of skin to lose their color. The study involves adults with progressive, non-segmental vitiligo, which means the condition affects both sides of the body symmetrically. The treatment being tested is a combination of a medication called anifrolumab and a type of light therapy known as phototherapy. Anifrolumab, also known by its code name MEDI-546, is given through an intravenous infusion every four weeks. Phototherapy involves exposing the skin to ultraviolet B (UVB) light twice a week.
The purpose of the study is to evaluate how effective this combination treatment is in helping the skin regain its color over a period of 36 weeks. Participants will be randomly assigned to receive either the combination of anifrolumab and phototherapy or phototherapy alone. The study will monitor changes in skin pigmentation using a scoring system called the Vitiligo Area Scoring Index (VASI). This will help researchers understand how well the treatment works in repigmenting the skin.
Throughout the study, the safety and tolerability of the treatment will be assessed through clinical and biological exams. Participants will have regular check-ups to monitor their progress and any potential side effects. The study aims to provide valuable insights into the potential benefits of combining anifrolumab with phototherapy for individuals with vitiligo.
