Filter by:The purpose of this study is to learn about the safety and effects of the study medicine ritlecitinib for the possible treatment of nonsegmental vitiligo. Vitiligo causes white patches on your skin when the cells that give your skin color are destroyed. Nonsegmental means that it can affect both sides of the body such as both knees and both hands. Ritlecitinib has been tested in earlier clinical studies and has a favorable safety profile. At present there are no approved medications taken by mouth to treat nonsegmental vitiligo. This study is seeking participants who: - Are 18 years of age or older. - are confirmed to have nonsegmental vitiligo for at least 3 months. - Are willing to stop all other treatments that they may be taking for vitiligo. In this study participants will be chosen by chance, like drawing names out of a hat to receive 1 of 3 treatments: •Part I where two different amounts of ritlecitinib (50 mg and 100 mg) are taken once daily. It will be compared to placebo. Placebo is a dummy capsule. It doesn't have any medicine used in the study. Participants receiving placebo who have not responded to treatment after 52 weeks will be given 100 milligrams or 50 milligrams of ritlecitinib for the remaining 52 weeks of the study. • In Part II, participants will only receive 100 milligrams of ritlecitinib. About 1000 participants will take part in Part I and around 450 in Part II globally. The study will compare the experiences of people receiving ritlecitinib to those of the people who do not. This will help see if ritlecitinib is safe and effective. People in Part I will be in this study for about 26 months and people in Part II will be in this study for about 14 months. During the study, participants in part I will need to visit the study site at least 17 times. In part II, participants will visit at least 11 times. Participants will undergo various tests and procedures such as: - vitiligo rating, - physical examinations, - hearing tests, - blood tests, - x-ray, - ECG, - photographs of areas with vitiligo. Participants will be asked to complete questionnaires about their vitiligo.
Vitiligo affects 0.5 to 2% of worldwide population and has a demonstrated impact on the quality of life. Optimal treatment of vitiligo requires to target the auto-immune inflammatory response (to halt the depigmentation process), but also to induce the differentiation of melanocyte stem cells (to induce repigmentation). There is a well demonstrated discrepancy in the repigmentation response between anatomical areas of the body. Face and neck are the best responder with complete or almost complete repigmentation achieved in most cases under treatment. Trunk and limbs could have a complete or almost complete repigmentation in approximately half of the cases. The repigmentation is much more difficult in wrists, elbows, knees, proximal part of the hands. Finally, some areas such as the extremities of hands and feet, palms, soles, are almost impossible to repigment. The investigator hypothesize that there are some factors that are produced in the skin that prevent (or at least decrease) the differentiation but also probably the migration and proliferation of melanocytes. Primary objective To compare the mRNA expression of each types of cells in the skin of vitiligo patients compared to healthy volunteers according to body locations
The goal of this pilot clinical trial is to assess the effectiveness of psychodramatic psychotherapy in reducing the psychological distress and/or the skin condition in patients with vitiligo. The main questions it aims to answer are: 1. Is there any improvement in terms of psychological distress in patients with vitiligo participating in a psychodramatic psychotherapy, compared to a control group? 2. Is there any improvement in terms of skin condition in patients with vitiligo participating in a psychodramatic psychotherapy, compared to a control group? Participants in the experimental group will receive the dermatological drug treatment usually recommended for vitiligo, and in addition they will participate in a 6 months psychodramatic psychotherapy. Researchers will compare the results of the experimental group with the results of a control group including vitiligo patients who will receive the dermatological pharmacological treatment usually recommended for vitiligo and participate in a 6 months program of self-help activities.
The purpose of this study is to perform an in-depth analysis of the molecular pathways involved in lesions responding to current treatment and lesions not responding to current treatment
The purpose of this phase 2 study is to evaluate the effect and the safety of the combination of ANIFROLUMAB in combination with phototherapy in adult participants with non-segmental progressive vitiligo
Medical approaches remain the gold standard treatment for non-segmental forms of vitiligo. Topical ruxolitinib cream has demonstrated its efficacy and good tolerance for treating vitiligo. While about 30% of patients will achieve at least 90% of repigmentation on the face after 1 year of treatment, some locations on the body, such as hands, feet, bony prominences remain highly challenging, and most patients won't get satisfactory repigmentation on those areas despite months of application of topical treatments, even when combined with UV. The poor rate of repigmentation in these locations are probably explained by the difficulty to stimulate the differentiation and proliferation of melanocytes stem cells in those areas. To study the efficacy at 3 months of epidermal cell suspension grafting followed by twice daily applications topical 1.5% ruxolitinib cream compared to epidermal cell suspension grafting followed by placebo in vitiligo resistant areas.There will be 2 arms with intra individual comparison. Both groups will receive epidermal cell suspension (provided by Cutiss®). After 7 days the dressing will be removed. Each grafted side of the body will be randomly assigned to receive twice daily application of topical 1.5% ruxolitinib cream (Group A) or twice daily application of placebo cream (Group B). After 3 months, both sides will be treated by twice daily applications of topical ruxolitinib for 3 additional months.There will be 8 visits in total during the 7 months duration for each subject.
Vitiligo is a common acquired depigmentation skin and mucosal disease in dermatology, with or without white hair. Vitiligo with white hair is difficult to treat. Phototherapy and topical therapy are the first line treatment methods for vitiligo. The peripheral leukoplakia irradiation of phototherapy covers the central area of the leukoplakia and performs phototherapy on the edge of the leukoplakia and surrounding normal skin. This study aims to compare the efficacy and safety of peripheral leukoplakia ultraviolet family phototherapy and leukoplakia family combination in the treatment of vitiligo.
To collect, preserve, and/or distribute annotated biospecimens and associated medical data to institutionally approved, investigator-directed biomedical research to discover and develop new treatments, diagnostics, and preventative methods for specific and complex conditions.
Metformin modulates metabolism in multiple cell types and is currently used to reduce glucose levels and insulin resistance in diabetic patients. The investigators hypothesize that oral metformin can regulate the metabolism of CD8+ T cells, reduce their cytotoxic activity and thus serve as a novel treatment for vitiligo.
