Psoriasis

This study is a randomized, double-blind, multi-center, parallel, phase II clinical trial, aiming to evaluate the efficacy and safety of SHR-1139 injection for adult patients with psoriasis. The trial includes a 4-week screening period, a 52-week treatment period, and a 12-week safety follow-up period. Approximately 60 patients with psoriasis are expected to participate.

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.

This trial is a Phase IIa clinical trial. Around 65 subjects will be enrolled into this study to primarily assess the treatment efficacy of 5% GM-XANTHO in patients with psoriasis, as well as the safety and tolerability of 5% GM-XANTHO. Two third of the total subjects will be given the investigational product, 5% GM-XANTHO, and the other third will take placebo. The treatment period will last for 28 consecutive days, followed by a safety follow-up for 2 weeks. During the study, there will be 8 scheduled visits to the clinical center.

Psoriasis is a common chronic inflammatory skin disease. Disease severity is commonly assessed using the Psoriasis Area and Severity Index (PASI), in which erythema is graded subjectively on a 0-4 scale. This visual assessment is prone to significant inter- and intra-rater variability. Although objective tools such as colorimeters provide accurate erythema measurement, their high cost limits routine clinical use. Smartphone imaging combined with artificial intelligence (AI) offers a practical alternative for objective assessment. However, variability in lighting conditions can affect image consistency. Incorporating a color calibration card enables accurate color normalization. This study aims to develop and validate an AI-based system for measuring erythema in psoriatic lesions using smartphone images with a color card, compared against a standard colorimeter to assess validity and reliability.

To assess the feasibility of AIGPP video interactions with psoriasis patients. To explore patient attitudes, trust, and comfort levels concerning AIGPP interactions in a healthcare setting, and to understand their influence on the patient-physician dynamic. To evaluate medication adherence over a 4-week period in patients with psoriasis randomized to weekly AI-generated automated physician providers (AIGPP) video interactions, weekly human video calls, or standard care (single follow up visit after 4 weeks). Adherence rates will be evaluated via a cap designed to record adherence attached to the study medication container.

Purpose and Hypotheses The purpose of this study is to find out if changing the diet and adding exercise can help children with psoriasis. Psoriasis is a skin condition that causes red, scaly patches and is linked to inflammation inside the body. We want to see if a special diet that avoids gluten and foods high in histamine can improve children's skin and reduce inflammation. We will also test if adding a fun physical therapy program with light exercise, stretching, and relaxation provides even more benefits, especially for their overall well-being and quality of life. Study Details: Study Duration: 14 weeks in total (this includes a 2-week screening period and the 12-week treatment period). Treatment Duration: 12 weeks. Visit Frequency: Participants will come to the clinic for assessments at the start of the study, after 6 weeks, and after 12 weeks. During the 12-week treatment period, participants in the exercise group will attend supervised physical therapy sessions three times a week. What Will Happen in the Study? Sixty (60) children aged 6 to 17 with mild to moderate psoriasis will be invited to take part. They will be put into one of three groups by chance, like drawing lots. One group will continue with their regular skin care. A second group will follow a special anti-inflammatory diet. This means they will avoid foods with gluten (like wheat bread) and foods high in histamine (like aged cheese or fermented foods) and will eat more fruits, vegetables, and healthy fish. A third group will follow the same diet and also take part in a physical therapy program three times a week. The physical therapy will include light exercise, fun movement activities, and relaxation exercises. Who Can Participate? We are looking for children who: Have been diagnosed with plaque psoriasis for at least 6 months. Have mild to moderate psoriasis. Are not taking any new psoriasis medications. Study Interventions: Dietary Intervention: A structured anti-inflammatory diet that is gluten-free and low in histamine. Physical Therapy: A supervised program of low-impact aerobic activities, stretching, and relaxation exercises. This study is not currently available through an expanded access program.

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.

The goal of this observational study is to evaluate nailfold capillaroscopic changes in patients with psoriasis and to assess their correlation with disease severity. The study will also explore differences in capillaroscopic findings across different clinical types of psoriasis and skin phototypes (Fitzpatrick classification). The study will include patients diagnosed with psoriasis attending dermatology outpatient clinics. Participants will undergo clinical assessment and nailfold capillaroscopy to detect microvascular changes.

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 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.

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.

Psoriatic arthritis (PsA) and ankylosing spondylitis (AS) are chronic inflammatory diseases within the spectrum of spondyloarthritis, characterized by immune-mediated inflammation and progressive functional impairment. Meteorin-like protein (Metrnl) is a novel adipomyokine with potential immunomodulatory and anti-inflammatory properties; however, its role in spondyloarthritis remains incompletely understood. This study aims to evaluate serum Metrnl levels in patients with PsA and AS compared with healthy controls and to investigate their association with disease activity, inflammatory markers, and clinical manifestations. The findings may provide insights into the potential role of Metrnl as a biomarker of disease activity and inflammation in spondyloarthritis.

To assess whether adding fractional laser to topical corticosteroid improves treatment outcomes in palmoplanter psoriasis compared to topical corticosteroid alone.

Everybody's skin has bacteria that normally lives on it. Previous research has shown that people with eczema (or atopic dermatitis \[AD\]) have much higher concentrations of a certain bacteria (S. aureus), especially when their disease is active but little is known about the role that this bacteria plays in psoriasis (i.e. disease severity, biomarkers and skin barrier function). The overarching purpose of this longitudinal study is to understand how the abundance of skin S. aureus (and several commensal bacteria) change as a consequence of standard of care treatment in the URMC dermatology clinics. Other assays and biospecimens will also be collected to address a number of questions.

Psoriasis is a common skin condition that leads to patches of scaled skin which can be inflamed, sore and itchy. It can affect any area of skin on the body, as well as nails, and can be widespread and severe. Over the past 20 years, many new treatments have been developed and approved for severe psoriasis. Most of these newer treatments are given by injection and, as a group, are known as biologics. Many people respond well to biologics and have a meaningful improvement in their condition. There is a smaller proportion of people who do not respond well, or develop side effects, and so must switch drugs to try and improve their condition. In some cases, people need multiple lines of biologic treatment. Currently very little is understood about how well people respond when they are treated with three or more biologics in a row, as very few trials have been done in these cases. This study aims to use data from people who have already been treated with biologics by their Dermatology teams in the NHS and use the information obtained during their normal clinic appointments to investigate this question. The investigators will assess how well people respond to each line of biologic drug (1st to 10th). They will look at whether people respond as well or less well over time, the more biologics they have. People can be included in the research if they are 18 or over and have been treated with a biologic for psoriasis in participating hospitals in the NHS in England. In this study the investigators are assessing data from events that have previously happened, and so no extra visits are required

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.

The goal of this clinical trial is to evaluate whether an electronic patient-reported outcome measure (ePROM)-guided flexible scheduling system can improve outpatient clinic resource utilisation in patients attending dermatology outpatient clinics for routine follow-up. The main questions it aims to answer are: * Does the intervention reduce the number of actualised outpatient visits over 12 months compared with standard fixed scheduling? * Does the intervention group achieve higher adherence to monthly ePROM monitoring, as measured by the proportion of completed ePROM submissions?

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.

Randomized, controlled trial, Proof of Concept, Phase 2 aimed to evaluate the effect of CBP-0276 in dose of 200mg twice dose a day, or placebo administrated for 36 weeks to improve Psoriasis Area and Severity Index (PASI)75 or static Physician's Global Assessment (sPGA) score of 0 or 1; PASI50, PASI90, PASI100, Scalp-specific Physician's Global Assessment (Ss-PGA) 0/1 with at least a 2-point improvement among patients with a baseline ss-PGA ≥3, sPGA 0, PSSD symptom score of 0 among patients with baseline score ≥1, Dermatology Life Quality Index (DLQI) 0/1 at Week 6,12,18,24, 30 and 36 among patients with baseline DLQI ≥2, adjusted by transcriptomics profile (post-hoc analysis), Percentage of subjects which achieve The Minimum Clinically Important Difference (MCID) on DLQI (a ≥4-point reduction from baseline) at Week 4 and 8, Frequency of solicited and unsolicited adverse events (SAEs and USAEs) (Medra), and Changes on inflammatory and anti-inflammatory cytokine levels during treatment (IL-17, IL-23, IL-6, TNF-alpha, IL1-b, IL-10).

Psoriasis is a chronic inflammatory disease that affects the skin and joints in 2-3 % of people in the United States. This inflammation of the skin, joints, and blood vessels in patients with psoriasis has been measured by older PET Scan technology but with limitations. With the new EXPLORER PET scanner technology, the investigators are testing to see if the EXPLORER is better than previous PET scanners and improve our ability to assess inflammation in patients. Also, it is known that the typical Western Diet - high in saturated fats, added sugars, and low in fiber - contributes to obesity and inflammation worldwide. There is evidence in animals that these signs of inflammation are reversible within 4 weeks when changed to a more balanced diet. Thus, this study aims to assess whether there are detectable decreases in inflammation of the skin and body of psoriasis patients who usually eat a Western Diet on an EXPLORER PET scan following 6 weeks of a more balanced diet.

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.

Chronic inflammatory skin diseases constitute a heterogeneous group of pathologies. They affect the skin but also other organs (joints, lungs, muscles, etc.). Their prognosis and response to treatments is extremely variable. The discovery of prognosis factors will help to precisely guide the treatment regimen and its intensification based on individual markers. The identification of new therapeutic targets is essential to develop new innovative treatments for inflammatory skin diseases. The main objective is to identify new cellular or molecular prognostic factors associated with treatment response at 1 year in inflammatory skin diseases. The secondary objectives are a better understanding of the pathophysiology of chronic inflammatory skin diseases, the identification of new cellular, molecular and microbiological prognostic factors associated with the clinical state after 10 years of evolution and the identification of prognostic markers of drug toxicity.

To evaluate the long-term efficacy of two maintenance treatment patterns of secukinumab-the standard maintenance group and the non-standard maintenance group-by assessing the median time to onset and incidence of secondary failure, as well as the time to regain response after dose escalation of secukinumab (including re-initiation of intensive dosing or shortening of the injection interval) in patients who experienced secondary failure.

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
