This clinical trial is focused on studying the effectiveness and safety of a treatment for vitiligo, a condition that causes patches of skin to lose their color. The study involves a combination of two treatments: methotrexate, a medication often used to treat certain autoimmune diseases, and a type of light therapy called UVB TL01 phototherapy. The purpose of the study is to evaluate how well this combination works in helping the skin regain its color in adults with progressive vitiligo, which means the condition is getting worse or spreading.
Participants in the study will receive either the combination of methotrexate and UVB TL01 phototherapy or a placebo. The study will last for about eight months, during which the participants will be monitored to see how much of their skin regains color. The study will also assess the safety of the treatment by checking for any side effects. The main goal is to see the percentage of skin that repigments, or regains color, in those receiving the combination treatment.
Throughout the study, various assessments will be conducted to measure changes in skin color and quality of life. These assessments will include the VASI score, which measures the extent of skin repigmentation, and the DLQI score, which evaluates the impact of skin conditions on daily life. Blood and skin samples will also be taken to check for any changes in inflammation. The study aims to provide valuable information on whether this combination treatment can be an effective option for people with vitiligo.
