Vitiligo

The purpose of this study is to evaluate how well LY4005130 is tolerated and what side effects may occur in participants with non-segmental vitiligo (NSV) when compared with placebo. The study drug will be administered intravenously (IV) (into a vein in the arm). Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body. The study will last approximately 48 weeks, including screening.

This is a randomized, double-blind, placebo-controlled Phase Ib/II clinical trial of multiple subcutaneous injections of GR2301 in combination with phototherapy to evaluate the tolerability, safety, pharmacokinetics, and preliminary efficacy in trial participants with vitiligo. The trial will be conducted in two stages: a dose-escalation stage (Phase Ib) and an expansion cohort stage (Phase II).

Investigators plan to perform a pilot study that aims to characterize the microbiome of human vitiligo patients with both active and stable disease and compare this to the microbiome of age and sex matched controls. The investigators aim to answer the question whether the gut and skin microbiome of patients with vitiligo differs from the general population.

This study tests D-2570, an investigational drug, in people with non-segmental vitiligo to check its safety and effect on skin discoloration. Eligible participants will take D-2570, or a placebo, once daily for 24 weeks in a double-blind setting. Most will then continue into a 24-week extension phase, where those on 27 mg or placebo will switch to one of the lower doses. All participants will have a 4-week safety follow-up after treatment ends, with regular check-ups and blood tests throughout the study.

The goal of this clinical trial is to evaluate the efficacy and safety of Ruxolitinib Phosphate Cream in treating non-segmental vitiligo in children aged 2 to 11 years under real-world conditions. The main question\[s\] it aims to answer are: Primary Efficacy: What is the improvement rate (e.g., proportion of participants achieving F-VASI75) after 24 weeks of treatment with Ruxolitinib Phosphate Cream in this population? Safety Profile: What is the safety profile of the treatment over 24 weeks, specifically regarding the incidence of Application Site Acne, Application Site Pruritus, and other adverse events? Participants will: Apply Ruxolitinib Phosphate Cream topically to vitiligo lesions as prescribed by the investigator. Attend scheduled clinic visits at Weeks 4, 8, 12, and 24 for efficacy and safety assessments. Undergo standardized clinical photography and severity scoring of their vitiligo lesions at each visit. Report any adverse events or skin reactions experienced during the study period to the research team.

Vitiligo affects approximately 1 to 2% of the global population and significantly impacts people's quality of life. areas of high stress. Ritlecitinib, an orally administered inhibitor of JAK3 (Janus kinase)/ TEC (tyrosine kinase expressed in hepatocellular carcinoma) has shown effectiveness and safety for the treatment of vitiligo. In a phase 2b trial, three doses of ritlecitinib, 200/50 mg, 100/50 mg, and 50 mg, were all statistically significant versus placebo on the Facial Vitiligo Area Scoring Index (F-VASI) at week 24 in patients with active NSV. Considering that the immune process primarily contributes to depigmentation while ultraviolet (UV) radiation stimulates the differentiation and proliferation of melanocyte stem cells for re-pigmentation, the investigators propose that a combination therapy using ritlecitinib and narrowband UVB (nbUVB) could offer an optimal approach for treating vitiligo patients. The primary objective is thTo compare between the groups, the mean percentage change from baseline in F-VASI and T-VASI at week 52. 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). More specifically, there will be 2 strata based on FST targets: (1) FST I to III (2) FST I IV, to VI. Each FST stratum will target to enroll at least 50% participants into the study population. Stratified randomization across FST sub-groups will support the evaluation of a consistent benefit-risk profile across all FST strata. Enrollment of participants with active or stable nonsegmental vitiligo will be proactively managed without formally capping or stratifying. Throughout the study, there will be a total of 8 visits conducted: selection, inclusion, week 4, week 12, week 24, week 36, week 52 and week 72. In patients who volunteer, a skin biopsy will be performed on both the lesional and perilesional areas at baseline, week 4 and week 52. We aim to include between 12 and 20 volunteer patients. Serum and plasma samples will be collected at the screening visit, week 4, week 12, week 24, week 36, week 52 and week 72. A pregnancy test will be performed every 4 weeks i.e. at weeks 8, 16, 20, 28, 32, 40, 44, 48, 56, 60, 64 and 68;

Vitiligo is the most common depigmentation disorder affecting around 1% of the population worldwide. Fifty two percent of patients develop vitiligo before the age of 20 and around 80% develop vitiligo before the age of 30 years old.1 Vitiligo often presents in childhood and tends to be a lifelong disease, requiring prolonged courses of phototherapy. Currently no national or international registry for patients with vitiligo exists. Individual dermatologists maintain a database of such patients, however no coordinated efforts have been made to combine these individual registries into a broader national registry. Finally, recently published British Association of Dermatologists (BAD) guideline for the management of vitiligo, recommended the development of a national registry for people with vitiligo undergoing systemic or light therapy to identify outcomes and safety.

This study evaluates whether exosomes derived from human umbilical cord mesenchymal stem cells (hUMSCs-Exo) are safe and effective for treating vitiligo in adults. Vitiligo is a skin condition that causes white patches due to loss of pigment-producing cells. Current treatments have limitations, especially for patients with active disease who require oral steroids with significant side effects. This study is a single-center, randomized, controlled trial enrolling 96 adults aged 18 to 65 years with non-segmental vitiligo. Participants are divided into two groups based on disease activity: progressive vitiligo (new patches appearing or existing patches expanding in the past 3 months) and stable vitiligo (no changes in the past year). For progressive vitiligo, participants are randomly assigned to either: Experimental group: hUMSCs-Exo given by intravenous infusion every 2 weeks for 5 sessions, plus tacrolimus ointment and narrowband UVB light therapy, or Control group: oral prednisone (a standard steroid treatment) plus tacrolimus ointment and narrowband UVB light therapy For stable vitiligo, participants are randomly assigned to either: Experimental group: hUMSCs-Exo given by local injection into the white patches every 2 weeks for 5 sessions, plus tacrolimus ointment and narrowband UVB light therapy, or Control group: tacrolimus ointment plus narrowband UVB light therapy alone The treatment period lasts 12 weeks, with follow-up visits continuing to 24 weeks. The main outcome measures include improvement in skin repigmentation measured by the Vitiligo Area Scoring Index (VASI), changes in quality of life, and safety monitoring throughout the study. This study aims to establish a standardized approach for using hUMSCs-Exo in vitiligo treatment and to explore how exosomes may work by reducing oxidative stress and regulating immune responses.

The goal of this clinical trial is to analyze the effectiveness of SM-hUCMSC secretome administered via microneedling and intradermal microinjection as adjuvant therapy to NB-UVB, compared with NB-UVB alone, in terms of repigmentation, onset of improvement, safety, patient satisfaction, and vitiligo recurrence. The main questions it aims to answer are: * Are there differences in the level of vitiligo lesion repigmentation among the secretome therapy via microneedling, intradermal microinjection, and NB-UVB phototherapy groups? * Are there differences in the time to onset of repigmentation among the treatment groups? What are the safety profiles and adverse events associated with each treatment modality? * Are there differences in patient satisfaction and quality of life after undergoing each therapy? * Are there differences in vitiligo recurrence rates during the follow-up period among the treatment groups? Participants will be allocated into three groups as follows: * Group A receives NB-UVB combined with microneedling and topical 10% secretome. * Group B receives NB-UVB combined with intradermal secretome injection. * Group C receives NB-UVB alone. The intervention period lasts 12 weeks, with follow-up until week 24.

The goal of this clinical trial is to learn if adding mini-oral pulse steroid therapy improves the results of non-cultured epidermal cell suspension (NCES) surgery in patients with stable vitiligo. It will also evaluate the safety of this treatment approach. The main questions it aims to answer are: * Does adding mini-oral pulse steroid therapy reduce the development of a perilesional halo after NCES surgery? * Does the addition of steroids improve the degree of repigmentation and overall treatment outcomes in vitiligo lesions? Researchers will compare NCES surgery with mini-oral pulse steroids to NCES surgery alone to determine whether the steroid therapy improves surgical outcomes. Participants will: * Undergo NCES vitiligo surgery for stable segmental or non-acral vitiligo lesions. * Be randomly assigned to receive either surgery alone or surgery plus low-dose oral mini-pulse dexamethasone therapy. * Attend follow-up visits and clinical assessments for approximately 4 months. * Receive excimer laser sessions twice weekly after healing and have standardized photographs and scoring assessments to evaluate repigmentation.

The goal of this clinical trial is to learn how well 5 fluorouracil (5FU) with micro-needling works to treat limited vitiligo as compared to strong steroid applied on skin. It will also learn about the safety of both these treatments. The main questions it aims to answer are: * How well does 5FU with microneedling work to treat vitiligo by returning pigmentation in vitiligo patches as compared to steroid? * What is participant's satisfaction when treated with 5FU with microneedling as compared to steroid? * What skin problems do participants have when treated with FU with microneedling and steroid? Researchers will compare 5FU with microneedling to steroid application to see how well both work to return pigment in vitiligo patches. Participants will be divided into two groups. For Group A, 5 FU will be rubbed and absorbed on the vitiligo patch after micro-needling every 2 weeks. For group B, topical 0.05% clobetasol propionate ointment will be applied twice a day on the vitiligo patches for 12 weeks. Vitiligo patches will be assessed at the start of trial and then after 12 weeks of treatment.

The goal of this clinical trial is to learn if drug CGB-600 works to treat vitiligo on the face and neck in participants between 18-60 years of age. It will also learn about the safety of CGB-600. The main questions it aims to answer are: Does CGB-600 decrease the severity of vitiligo on the face and neck? What medical problems do participants have when taking drug CGB-600? Researchers will compare CGB-600 to a non-active drug (vehicle) to see if CGB-600 works to treat vitiligo. Participants will: Apply face twice daily for a period of 24 weeks. Visit the clinic 8 times for checkups and tests.

This multicenter retrospective observational registry study will collect existing clinical data from Italian centers to describe epidemiology, treatment patterns, clinical evolution, safety, and comorbidities in patients aged 12 years and older with psoriasis, atopic dermatitis, vitiligo, alopecia areata, or hidradenitis suppurativa.

This clinical trial aims to compare the efficacy and safety of central nevus removal versus conservative treatment in patients with halo nevus accompanied by non-segmental vitiligo. It is a single-center, prospective, randomized controlled trial involving 60 participants aged 6 to 45 years, who will be randomly assigned to either the nevus removal group or the conservative treatment group. The removal group will undergo surgical or laser excision of the central nevus followed by medication, while the conservative group will receive medication only. Both groups will be followed for 6 months. Outcomes include repigmentation assessment using vitiligo scoring indices, quality of life measures, and serial serum cytokine profiling. The study seeks to provide high-level evidence to guide clinical management of halo nevus with vitiligo. Key points: 1. For patients with halo nevus accompanied by non-segmental vitiligo. 2. For patients aged 6 to 45 years. 3. Compares nevus excision and conservative treatment. 4. Follows participants for 6 months. 5. Focuses on effectiveness and safety.

A novel approach for 5-Fluorouracil delivery based on a solid effervescent formulation is proposed . 5-Fluorouracil is water soluble (\~50mg/ml) and therefore has been used for the development of novel topical formulations including nano and microparticles intended for skin targeting. After hydration 5-Fluorouracil could form a complex, a suspension or even be formulated to generate effervescence. In effervescent technology, gas bubbles occur from the liquid after chemical reaction between alkali salts and organic acids (mainly citric or tartaric. Due to liberation in CO2 gas, the dissolution of drug in water is enhanced. The aim of this study is the development and clinical evaluation of topical 5-florouracil effervescent powder formulation in the treatment of vitiligo.

Vitiligo is a common chronic autoimmune skin disease that can occur on any part of the body and severely impacts patients' quality of life. Current treatment for vitiligo primarily include topical medications, phototherapy, systemic therapy and surgical interventions, but their efficacy is limited, often failing to achieve ideal therapeutic outcomes, and are associated with a high recurrence rate. This study is an investigator-initiated real-world research on the application of ruxolitinib cream for vitiligo treatment, with the primary objective of exploring the factors influencing the efficacy of ruxolitinib cream in treating vitiligo.

Vitiligo is a chronic autoimmune disorder characterized by depigmented patches on the skin, which can pose significant psychosocial challenges, particularly for individuals with darker skin tones. Compared to the general population, individuals with vitiligo are more likely to experience immune-mediated diseases or psychological comorbidities. Studies confirm that the combined prevalence of depression and anxiety among vitiligo patients reaches 8% and 35.8%, respectively. Notably, the anxiety prevalence rate is comparable to that seen in other severely debilitating skin conditions such as eczema and psoriasis. However, the progression, stability, and recurrence of vitiligo exhibit high unpredictability. Unlike other inflammatory skin diseases such as psoriasis or atopic dermatitis, there is currently a lack of objective, sensitive biological markers in clinical practice to predict disease activity, forecast treatment response, or assess long-term prognosis. Decisions primarily rely on the attending physician's assessment of disease activity, affected areas, severity, and repigmentation potential. Furthermore, clinical signs of active vitiligo are only observable in some active-phase patients, introducing delays and subjectivity. This leads to reactive treatment decisions, increasing the likelihood of missing the optimal intervention window. Cytokines are small-molecule polypeptides or glycoproteins synthesized and secreted by the body's cells, possessing diverse biological activities. They play a central role in physiological and pathological processes such as immune regulation, anti-infection, and anti-tumor responses. The "Twelve Cytokine Panel" is a clinical test utilizing advanced flow cytometry for the combined analysis of 12 core cytokines. The cytokines included in this test are IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17, IFN-α, IFN-γ, and TNF-α. This panel comprehensively reflects innate immune and T-cell immune responses, providing crucial laboratory evidence for evaluating the functional status of the immune system and inflammatory network. Cytokines serve as core messenger molecules in the autoimmune pathogenesis of vitiligo, forming a complex inflammatory network that governs the entire process of immune attacks against melanocytes. Consequently, detecting specific cytokine profiles not only deepens our understanding of vitiligo's disease mechanisms but also holds immense potential clinical value in assessing disease activity, monitoring treatment efficacy, and developing novel targeted therapies.

Vitiligo is a skin disorder that results in the formation of depigmented patches or hypopigmented macules due to selective destruction or reduction of melanocytes the cells that produce pigment in our skin. Vitiligo affects 0.1-2% of the World's population. People of all skin types and all ages can be affecte. In most of the cases, white patches develop or expand slowly overtime, and in some cases it never progress and remains stable . Vitiligo can be segmental or non-segmental depending upon the morphology of the clinical involvement. It can also be classified as stable or unstable based on the activity of disease. Steroids act as anti-inflammatory and immunosuppressant agents. Even if different classes of steroids are now available, the mid- potent ones (e.g. betamethasone dipropionate 0.05% cream, 0.05% clobetasol propionate ointment) are usually preferred for the treatment of young patients . Now days, topical corticosteroids are the most commonly prescribed agents in treatment of dermatologic conditions .Almost all treatments of vitiligo have borrowed from therapies whose prime targets have been another disease.

This randomized controlled trial aims to compare the efficacy of needling versus microneedling, both followed by narrowband UVB therapy, in achieving repigmentation in patients with localized stable non-segmental vitiligo.

The goal of this clinical trial is to learn if topical crisaborole ointment works to treat vitiligo. It will also learn about the safety of the drug. The main questions it aims to answer are: Can the drug cause repigmentation of vitiligo lesions when used as topical form after microneedling? What medical problems do participants have when the drug used? Participants will: Visit the clinic once every 2 weeks to have the microneedling sessions for 3 months. and also they will have narrow band UVB sessions two times per week. Record any side effect they have during or after the sessions.

This clinical study aims to compare the safety and effectiveness of two treatments-oral Tacrolimus capsules and Dexamethasone micro-pulse therapy-in children aged 4-12 years with rapidly progressing vitiligo. The study is a multicenter, randomized, controlled trial involving 90 participants, who will be divided equally into two groups. One group will receive daily Tacrolimus, while the other will take Dexamethasone on weekends. Over 24 weeks, doctors will monitor improvements in skin repigmentation, side effects, and overall health through regular check-ups and blood tests. The goal is to determine which treatment better controls disease progression and improves quality of life for children with vitiligo. Key Points: * For children with rapidly spreading vitiligo. * Compares two common medications. * Follows participants for 6 months. * Focuses on safety and effectiveness.

Assessing the additive value of mini-oral pulse steroid therapy in surgical treatment of acral and difficult to treat sites of vitiligo

this is a prospective, randomized controlled trial (RCT) investigating the immunological effects of narrowband UVB (NB-UVB) phototherapy-both as monotherapy and in combination with oral mini-pulse (OMP) steroids-in non-segmental vitiligo patients. The study evaluates changes in CXCL11 (a chemokine involved in T-cell recruitment) and TEMRA (terminally differentiated effector memory T cells re-expressing CD45RA) levels in serum before and after treatment.
