Psoriasis

This phase Ib trial studies the side effects of nivolumab and to see how well it works alone and in combination with other treatments, such as ipilimumab, cabozantinib, platinum containing therapy, and fluoropyrimidine, in treating patients with autoimmune disorders and cancer that has spread from where it first started (primary site) to nearby tissue, lymph nodes, or distant parts of the body (advanced), to other places in the body (metastatic) or cannot removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib blocks certain proteins, which may help keep tumor cells from growing. It may also prevent the growth of new blood vessels that tumors need to grow. Cabozantinib is a type of tyrosine kinase inhibitor and a type of angiogenesis inhibitor. Chemotherapy drugs, such as platinum containing therapies and fluoropyrimidine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab alone and in combination with other treatments, including ipilimumab, cabozantinib, platinum containing therapy, or fluoropyrimidine, may be safe, tolerable, and/or effective in treating patients with autoimmune disorders and advanced, metastatic, or unresectable cancer.

The purpose of this post-marketing study is to assess the amount of guselkumab in breast milk of lactating women receiving guselkumab as part of their standard clinical care provided by their treating physician, for any of the approved indications. This is a fully remote (virtual) study. Participants can complete all study-related activities, including consent, study visits, and breast milk sample collection, from home without attending an in-person study site.

This study will evaluate whether pentoxifylline, when used as an add-on treatment to standard topical therapy, is effective and safe for adults with mild-to-moderate plaque psoriasis. Participants will be randomly assigned to receive either pentoxifylline or placebo twice daily for 12 weeks, while continuing their standard topical treatment. The study will compare improvement in psoriasis severity, itch, physician assessment, quality of life, and adverse events between the two groups. Participants will be followed for a total of 16 weeks.

Psoriasis is a chronic inflammatory condition driven by a complex interplay between heritable and microenvironmental factors. Genome-wide heritability for psoriasis (PsO) is estimated at up to 50%. Although bearing genetic susceptibility at birth, most patients will remain disease free for years until an exposomal trigger activates the immunological pathway that leads to the first disease flare. In rare patients, the first flare is an isolated event, but in most patients it will evolve into a chronically relapsing-remitting disease characterized by lasting lesions and recurrent flares. Primary objective is to compare efficacy of bimekizumab versus topical corticosteroids on psoriasis clinical disease activity, assessed by PGA, at week 16 and week 24. Patients will be randomized 1:1 to receive either 320mg bimekizumab at weeks 0 (W0), W4, W8 and W12, or clobetasol ointment for 2 to 4 weeks until complete clearance of the lesion. After a maximum of 4 weeks topical clobetasol will be applied twice weekly on the site of lesion until week 16 then stopped. Patients will not receive active treatment between week 16-24. Between week 24-96 patients that flare can receive continuous topical clobetasol if needed. These patients will be considered non-responders at subsequent timepoints for the main analysis. If the patients worsen their psoriasis under the treatments given during the study and progress to moderate or severe psoriasis (PASI 10 and above) they will end their participation to the study to receive a treatment adapted to the new severity of their psoriasis. The patients will be referred to their dermatologist to receive the actual standard of care adapted to their new condition. During the study, the following assessments will be performed and samples will be collected

Dendritic cells (DC) paly a key role in the induction and chronicity of psoriasis by capturing the antigenes and activating the T cell repsonse. This activation requires their migration from the cutaneous sensitisation site to the lymph nodes. This migration requires an important intracellular metabolic activity, with a strong involvmenet of glucdic metabolism. This activity is linked with the systemic activity. This study aims to compare the migration and the phenotypic and metabolic caracteristics of blood and skin DCs in patients with or without psoriasis and with or without type 2 diabetes,

The main purpose of this study is to describe how well Guselkumab works after switching from Ustekinumab in participants with moderate to severe psoriasis in a routine clinical setting. A long-term skin disease that causes red, scaly and sometimes painful, itchy patches on the skin.

The purpose of this trial is to learn about a trial medicine called MK-8644. This trial is the first time researchers will give MK-8644 to people. This trial will help researchers learn about the safety of MK-8644 and if participants tolerate it. Tolerate means participants will receive MK-8644 in the trial unless they need to stop it due to health problems.

This study aims to assess the proportion of participants with moderate-to-severe plaque psoriasis who continue treatment with guselkumab over a two-year period.

This is a multicenter, prospective, randomized, open-label, controlled clinical investigation to evaluate whether Ceramol PSOR cream, used as an adjuvant treatment, is superior to a comparator emollient cream in patients with mild-to-moderate plaque psoriasis undergoing narrowband UVB phototherapy. Participants apply the assigned cream topically once daily throughout one standard phototherapy cycle (36 ± 3 UVB sessions). The study assesses clinical response (PASI, body surface area), subjective symptoms (pruritus and dryness/tightness VAS), quality of life (DLQI), treatment satisfaction, and adherence to both the investigational product and phototherapy.

Skin diseases, despite low mortality, significantly impair quality of life. This randomised controlled trial evaluates the efficacy of a digital toolkit comprising psychotherapeutic strategies in reducing QoL burden in patients with chronic inflammatory skin conditions. This toolkit is hosted on a mobile application and will be used by study participants randomised to the intervention arm over the 32 week study period.

Over 300 million people around the world struggle with skin conditions like eczema and psoriasis, which cause ongoing discomfort and emotional stress. In the UK, these conditions are diagnosed by doctors looking at the skin to assess the severity of the disease, but delays in seeing specialists contribute to long waiting times in the NHS. To tackle these problems, the investigators have created a device that safely uses sound waves to measure skin properties, like stiffness and moisture. Unlike just looking, this device gives clear, data-based insights into skin health, which the investigators hope will enable us to accurately measure disease severity without the need to wait for a dermatologist appointment. This should speed up specialist referrals and allow us to tailor treatment options more effectively, earlier on. In our study, we want to prove that these sound wave measurements match up with disease severity and treatment success in eczema and psoriasis cases. We'll compare the results with those from dermatologists. We are looking for 20 volunteers with eczema or psoriasis who are about to start treatment. Volunteers will be scanned with our device alongside their regular skin examinations. We'll gather some extra information through questions and photos (optional), but no additional treatments or painful procedures are involved.

This trial tests whether a Unani ointment (Marham-e-Asfedaj) plus an oral Unani formulation (Mundij wa Mushil-i Sawdā) works better than a active treatment (salicylic acid 3% solution, also combined with Mundij wa Mushil-i Sawdā) for treating chronic plaque psoriasis in adults. It will also check whether Marham-e-Asfedaj is safe to use. Main question: Does adding Marham-e-Asfedaj to Mundij wa Mushil-i Sawdā work better than adding salicylic acid 3% solution to Mundij wa Mushil-i Sawdā? What participants will do: * Take a Unani oral medicine (Mundij wa Mushil-i Sawdā) once a day for the first 40 days * Have two matching psoriasis patches treated differently - one side of the body (chosen at random) gets a Unani ointment (Marham-i-Asfedaj), and the other side gets a standard treatment (coal tar 1% + salicylic acid 3%). Both are applied twice daily from day 1 to day 60 * Give blood samples to check general health, liver, and kidney function, and have a small skin sample taken (biopsy) at the start (day 0) and end of treatment to see how the histological morphology has changed * Come in for check-ups on days 0, 15, 30, 45, and 60, with a final follow-up visit one month after treatment ends * Not use any other psoriasis treatment during the study, so the results reflect only the study treatments Trial duration: 60 days of treatment, plus a follow-up visit 1 month later - so each participant is involved for about 3 months total. What the study is measuring (outcome measures): * Severity of psoriasis, tracked using two standard scoring tools (PASI and SPI), checked five times during treatment * Quality of life, using a standard skin-disease questionnaire (DLQI), checked at the same visits * Skin changes under the microscope, comparing biopsy samples from before and after treatment * Safety, through blood tests checking overall health, liver, and kidney function

Background: The immune system is the part of the body that fights infection. Some people have immune deficiencies that cause skin rashes, make them get sick often with infections, or make it difficult for their skin to heal. Researchers want to learn more to better treat conditions that affect immune response. Objective: To learn about how the immune system and skin healing are related to each other. Eligibility: People ages 18-75 with primary immune deficiency, eczema, or psoriasis. Healthy volunteers are also needed. Design: Participants will be screened with a medical and medicine history and a physical exam. They may take a pregnancy test. Participants will discuss the medicines or supplements they take as well as skin products they use, such as soaps and lotions. Participants will have up to 4 skin biopsies taken from the forearm. A needle will inject an anesthetic into the skin where the biopsy will be done. A sharp tool that looks like a tiny cookie cutter will be used to remove a round plug of skin a bit smaller than the tip of a pencil. Participants will give at least 1 blood sample. Participants may have optional skin swab collection. A cotton swab will be used to swab the skin on the arm. Participants may have optional skin tape collection. A sticky strip of tape will be placed on the arm and then removed. Participants may give leftover samples taken as part of their regular medical care. Participation will last for about 4 days. Participants will have 2 visits that each last about 1 hour. They may be asked to repeat the study in the future.

This PMCF study is to obtain patient feedback using online questionnaires. There will be no involvement from healthcare professionals (HCPs) or investigator sites. Up to 100 Patients are being recruited by My Health Focus through their website. The study is performed throughout the UK except Northern Ireland with no sites involved in this study. Patients apply directly to participate in the study and the testing and questionnaire responses are completed at home.

The goal of this clinical trial is to demonstrate the feasibility of a trial that examines the impact of changes in dietary sodium intake on skin sodium levels, atopic dermatitis, and psoriasis. In addition, it aims to generate preliminary data to begin to answer the following questions: 1. Is there an association between skin sodium concentration and atopic dermatitis and psoriasis severity? 2. Are changes in dietary sodium are associated with changes in skin sodium concentration and atopic dermatitis and psoriasis severity? Researchers will compare sodium tablets to a placebo (a look-alike substance that contains no drug) to specifically examine the impact of altering sodium intake. Participants will: * Follow a low-salt diet for the duration of the 13-week study * Take sodium chloride tablets every day for 5 weeks followed by a placebo every day for 5 weeks after a 2-week washout period, or vice versa * Visit the clinic up to 4 times to answer questionnaires, provide bio samples, complete dietary recalls, and undergo non-contrast sodium MRI

This study is a multicenter, randomized, double-blind, placebo- and active-controlled Phase III clinical trial sponsored by Nanjing Shunxin Pharmaceutical Co., Ltd., a subsidiary of Chiatai Tianqing Pharmaceutical Group. The study aims to evaluate the efficacy and safety of once-daily oral TQH3906 capsules (24 mg) in adult participants with moderate to severe plaque psoriasis. TQH3906 is a highly selective TYK2 allosteric inhibitor targeting the JH2 domain, which blocks the IL-23 and Type I interferon inflammatory pathways. Approximately 400 eligible participants aged 18-75 years will be enrolled. Participants will be stratified based on prior biologic use and randomized in a 2:2:1 ratio to the TQH3906 group, the deucravacitinib active control group, or the placebo group. The trial includes a screening period, a 16-week double-blind controlled treatment phase, a 36-week open-label extension phase (during which all participants will receive TQH3906), and a 4-week safety follow-up after the last dose. The co-primary endpoints are the proportion of participants achieving sPGA 0/1 and PASI 90 response at Week 16. Secondary endpoints include improvements in scalp, nail, and palmoplantar psoriasis, Dermatology Life Quality Index (DLQI), long-term safety, and steady-state pharmacokinetic parameters. This study will collect comprehensive efficacy and safety data over 52 weeks to support the New Drug Application (NDA) for TQH3906 for the treatment of plaque psoriasis.

The main purpose of this study is to assess the effectiveness of adding tirzepatide to ixekizumab therapy in standard clinical practice in participants with moderate-to-severe plaque PsO and obesity or overweight with at least 1 weight-related comorbidity. The study will last up to 12 months.

This study is designed to provide treatment with deucravacitinib for participants with SLE/SjD (Systemic Lupus Erythematosus/Sjögren's Disease) and pediatric participants with PsO/PsA (Psoriasis/Psoriatic Arthritis) who have completed their qualified parent studies and/or long-term extension if applicable.

In this study, participants will have 3 or 4 total study visits over approximately 10 total weeks. There is a two week medication washout period in between the 1st and 2nd visits. This washout only applies if participants are using a prohibited psoriasis medication (such as topical steroids or oral psoriasis medications, like methotrexate). During the washout period, participants will have to stop the prohibited medication(s). If participants are not using any prohibited medications, then the 1st and 2nd visits can be combined and participants will only have 3 total in-person visits. Participants will be randomly assigned (by chance; like flipping a coin) to either the Mediterranean Diet or no dietary intervention. After 4 weeks on the diet, participants will start treatment with either Anti-IL-17 or Anti-IL-23 therapy. The biologic treatments will prescribed by the participants regular dermatologist and not as a part of the study.

Psoriasis, atopic dermatitis (eczema) and hidradenitis suppurativa are long-term skin conditions that flare and settle over time. Most of what happens to the skin happens at home, between hospital appointments. A dermatologist usually sees the skin only on the day of the visit, which may not reflect how the condition has been over the preceding months. This study sets up a long-term research collection, called a cohort, in which people with one of these three conditions take part from home. Once a month, participants use a certified digital health app on their own phone to answer a short set of questions about their symptoms and about how their skin affects daily life, and to take a standard set of photographs of their skin. Twice a year they answer a longer set of questions. Taking part takes about five minutes in most months and about twenty-five minutes twice a year. The app gives step-by-step guidance on lighting, distance and framing at the start of every photo session, so that the photographs can be compared from month to month. The photographs are reviewed by trained assessors, who score how severe the skin disease looks using the scoring systems established in dermatology research. Three assessors score each set of photographs independently, and their scores are combined according to rules that are set in advance. With the participant's permission, this information is combined with information already recorded during routine care, such as changes in treatment and hospital visits; with pharmacy records showing which medicines were dispensed; and with publicly available daily measurements of air quality, sunshine, ultraviolet radiation and pollen for the area where the participant lives. Bringing these together makes it possible to study how these conditions change over time, what happens in the period before a flare, and how treatment and the living environment relate to the course of the disease. The collected data are also intended to support the development of computer-based tools that could in future help assess skin disease from photographs. Taking part does not change the care a participant receives. The study does not provide medical advice, and the data collected are not used for diagnosis, treatment decisions or routine follow-up. Participants who experience worsening symptoms contact their treating physician as usual. The cohort is also designed so that studies of digital care tools can later be carried out within it, among participants who have agreed in advance to be approached. Each of those studies is registered separately.

The objective of the resarch is to study the cytokine profile of patients with psoriatic arthritis and psoriasis in order to better understand the pathophysiology of the disease and the contribution of cytokines to the presence or absence of joint involvement. This research will compare cytokines levels in sera, in PBMC culture after LPS or CD3/CD28 agonist antibodies, and in skin biopsy.

The primary objective of the CorEvitas Psoriasis Registry is to study the comparative safety of approved psoriasis therapies in a North American cohort of psoriasis subjects treated by dermatologists. This includes assessing the incidence and nature of adverse events of special interest, including malignancy, in a real world population of psoriasis patients on new biologic therapies (e.g. secukinumab). Secondary objectives include analyzing the epidemiology and natural history of the disease, comorbidities, current treatment practices, and comparative effectiveness.

The goal of this intervention study is to assess the Safety, Tolerability, Pharmacokinetics, and Immunogenicity of HCXT-2001 Tablets and HCXT-2001 Tablets(A) in Healthy Participants. The main parameters it aims to answer are: Does a single dose of HCXT-2001 Tablets and HCXT-2001 Tablets(A) in healthy participants impact the Safety, Tolerability, Pharmacokinetics, and Immunogenicity profiles? This study will be a - randomized, double blind, placebo-controlled study.

This is a 24-week prospective, single-arm cohort, study of patients initiating advanced therapy for the treatment of moderate-to-severe plaque PSO. Eligible patients must be willing to be seen in-person by their treating physician for a Baseline visit (with first dose of the advanced therapy occurring within 14 days), and at 16 (+/- 5 days) and 24 weeks (+14 days) calculated based on date of first dose of the advanced therapy and must provide informed consent prior to enrolling in the study or completing study-specific questionnaires or procedures. Data will be collected from both subjects and their treating dermatology provider at predetermined scheduled intervals (Baseline, Week 16 and Week 24) using a structured and standardized data collection tool.
