Active clinical trials for "Psoriasis"

The study has been designed with three components. Part A is an open label PK study followed by a randomized trial component (Part B) followed by open label Long Term Extension (LTE). The initial PK analysis is first done in adolescent subjects (12 to <18 years) before initiating the PK study in younger cohort (6 to <12 years)

Psoriasis is a systemic chronic inflammatory immune-mediated disease whose etiopathogenetic mechanisms involve genetic predisposition, and immunological and environmental factors. Its prevalence is about 3% in adults, and it is characterized by well-demarcated, erythematous plaques, covered by silvery-white scales, in elbows, knees, trunk, and scalp. However, psoriasis is far from being considered just a dermatologic condition because the cytokine's cascade, which lays behind its inflammatory and immune-mediated pathogenesis, can determine multiple systemic manifestations. In addition, several patients with psoriasis often complains of gastrointestinal (GI) symptoms. Therefore, authors focused their attention over the gut-skin axis and its possible pathogenetic and immunoregulatory role in psoriasis (i.e., altered gut barrier, increased blood concentration of gut microbiota-derived metabolites, systemic inflammation). In this context, several dietetic approaches (e.g., Mediterranean, low calories, protein-restricted, vegetarian diets, and gluten-free diet, GFD) have shown a certain efficacy in improve psoriasis cutaneous and systemic manifestations. In recent years, the existence of a wheat-related disorder in patients who do not suffer from CD or wheat allergy (WA) has been definitively ascertained and defined as Non-Celiac Wheat Sensitivity (NCWS). Its prevalence in the general population is unknown, but self-reported NCWS is around 10%. This condition is characterized by both GI and extraintestinal symptoms, which are triggered by wheat ingestion. In these patients, wheat ingestion might lead to alteration in intestinal permeability and gut microbiota and to systemic immune activation and inflammation. Based on the evidence of gut involvement in the pathogenesis and clinical manifestation of psoriasis, as well as on the ability of gluten/wheat to increase intestinal permeability, it could be hypothesized that gluten/wheat may represents one of the pathogenetic environmental factors of psoriasis and that its intake may be able to worsen symptoms in affected patients. The investigators hypothesize that a wheat-free diet (WFD) can reduce the inflammatory state and ameliorate the clinical symptoms in psoriasis patients. The successive clinical and immunologic reaction to the re-exposure to wheat ingestion, performed by an open challenge, will be also evaluated to confirm a wheat-dependent mechanism and to understand the underlining physiopathology.

Through the combination of clinical manifestations and omics, the investigators aim to explore the skin cell atlas in different stages of psoriasis lesions, establish a clinical classification standard for psoriasis, and guide the precise treatment of psoriasis.

The purpose of this study is to determine the efficacy and safety of the study drug recombinant anti-IL-17A humanized monoclonal antibody in Chinese participants with moderate-to-severe plaque psoriasis.

The aim of the present study is to evaluate the efficacy of intralesional injection of methotrexate in comparison with Intralesional Injection of Triamcinolone Acetonid in localized psoriasis (body surface area < 10%) .

Psoriasis, a common chronic inflammatory skin disease affecting approximately 2% of the population, is associated with increased cardiovascular (CV) risk. Despite the implication of inflammation in this excess risk, it remains unclear whether reducing inflammation reduces the risk of cardiac events. This study proposes to test whether Tildrakizumab, an FDA approved therapy for psoriasis that blocks IL-23 and the Th17 pathway of inflammation, improves coronary vascular function and coronary flow reserve, as measured by noninvasive imaging with cardiac positron emission tomography. In so doing, improvement in coronary vasoreactivity, endothelial function, and tissue perfusion may have beneficial effects on myocardial mechanics, left ventricular deformation and function and, ultimately, symptoms and prognosis. This research may offer novel insights into the contributors of CV risk in psoriasis and provide data to support the development of strategies to prevent cardiovascular events in psoriatic disease.

Psoriasis has been associated with an increasing risk for atherosclerosis. The investigators investigated whether surrogate markers of subclinical atherosclerosis, vascular dysfunction and myocardial dysfunction are impaired in patients with psoriasis compared to normal controls ,coronary artery disease patients and untreated hypertension subjects. The investigators also examined the effect of treatment with biological vs no biological agents on vascular and LV function in psoriasis.

The purpose of this study is to evaluate the efficacy and safety of guselkumab in pediatric participants aged greater than or equal to 6 through less than 18 years with chronic plaque psoriasis.

These studies are designed to assess the synergistic efficacy of topical 0.1% triamcinolone cream paired with 40,000 IU of oral vitamin D3 daily in treating mild to moderate psoriasis. The study is designed to have all subjects treated with triamcinolone cream (TAC) for 4 weeks, then will be randomized 1:1 into vitamin D3 or placebo for an additional 12 weeks. At that time, the study will become open-label and all subjects will be placed on (or continue) vitamin D3 for an additional 12 weeks. The study will take place over 28 weeks total.

This study seeks to evaluate the safety, tolerability, and efficacy of topical Duobrii® Lotion in adult subjects with mild plaque psoriasis.
