This study is being conducted to determine the efficacy and safety of povorcitinib in participants with nonsegmental vitiligo.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of MK-6194 in participants with non-segmental vitiligo. The primary hypothesis is that at least 1 MK-6194 dose is superior to placebo with regards to percent change from baseline in Facial Vitiligo Area Scoring Index (F-VASI) at Week 24.
The CUV105 study will assess the efficacy and safety of afamelanotide and NB-UVB light in patients with vitiligo on the body and face versus NB-UVB light alone.
Vitiligo is an acquired, non contagious skin disorder characterised by depigmented patches of skin that may appear in a localised or very generalised distribution, and affecting 0.5-2.0% of the global population.There are however, limited population-based studies on the burden of vitiligo and disparities across people of different ethnicities and deprivation. The overall purpose of this study is to provide an estimate of the lifetime risk of vitiligo in the population overall and by sociodemographic subgroups. Moreover, to do a subgroup analysis in the vitiligo population to identify health-related disparities across people in different sex, age, deprivation and ethnicity. A detailed understanding of the burden of disease in different sociodemographic groups is vital to plan resource provision.
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
Vitiligo is a auto immune that impact 2% of the global population, regardless from the phototype. Even though it affects patients in a physical way through loss of pigmentation, it is also impacting them on a mental/emotional way.11-12 Current treatments offer a symptomatic solution to patients, however the response rate can be low and results can be slow. Pediatric patients in vitiligo deserves special care as frequently (50%), the disease onset is before 20 years of age and, in 25% of the cases, it starts before the age of 10 years.13 Also, the current treatments for children are limited since it can involve pain and claustrophobia. The combination therapy of the study could offer a painless and easy treatment to follow. If the combination of those two therapies can fasten and improve the response rate, this could be a good option to treat this condition not only in children, but also for adults patients.
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.
Vitiligo is characterized by the selective loss of melanocytes, which in turn leads to totally amelanotic, non-scaly, chalky-white macule with distinct margins Vitiligo is the most common depigmenting skin disorder, with an estimated prevalence of 0.5-2% of the population in both adults and children worldwide Tumor necrosis factor (TNF-α), a pro-inflammatory cytokine is necessary for Th1 mediated response and immune homeostasis and the up-regulation of TNF-α can result in chronic inflammatory and autoimmune diseases . previous studies revealed a rise in transcript and protein levels of TNF-α in vitiligo patients The prime location of melanocytes, keratinocytes and fibroblasts is the epidermal microenvironment and these cells are capable of TNF-α expression and secretion TNF-α acts as an autocrine as well as a paracrine manner to suppress the melanocyte growth and proliferation ( Tristetraprolin (TTP) zinc finger protein 36 (ZFP36) is Ribonucleic acid (RNA) binding protein that preferentially binds to Adenylate-uridylate-rich (AU-rich) regions in the 3' untranslated regions (3'UTR) of target genes . Additionally, Tristetraprolin functions by destabilizing mRNAs encoding for oncogenes, cytokines (as TNFα), and chemokines involved in the inflammatory processes, by favoring their degradation and/or preventing their efficient translation The expression of proinflammatory mediator genes is tightly controlled by post-transcriptional regulation, which is mediated by a set of immune-related RNA binding proteins, such as tristetraprolin, Roquin, and Regnase
