Active clinical trials for "Psoriasis"

Comparison of two dosing regimens of Alefacept in subjects weighing between 100kg and 150kg with moderate to severe Chronic Plaque Psoriasis

The study was double-blind, randomized, vehicle-controlled study with application of Ruxolitinib phosphate cream or vehicle cream in participants with stable plaque psoriasis applied once daily for 12 weeks without occlusive dressings. There were 4 treatment groups anticipated to have 50 participants in each.

Patients will be randomly assigned (1:1:1 ) either to ; NB-UVB photo-therapy alone , Acitretin therapy alone or NB-UVB photo-therapy combined with Acitretin therapy randomization will be done by closed envelopes . investigator will be blinded to study drug assignment , while patients and data interpreter will not be masked to study drug assignment.

Purpose and rationale: To define the role of IL-17 as a mediator of structural bone lesions in psoriasis patients and patients with PsA. Primary Objective is the improvement of the PsAMRIS synovitis score baseline vs. week 24. Drug tested is Secukinumab 300 mg administered weekly for 4 weeks, then 4 weekly s.c. with a duration total of 24 weeks. Indication for this study is Psoriasis (Pso) and psoriatic arthritis (PsA).

The study is designed to explore the kinetics of psoriasis symptoms, pruritus intensity and lesional biomarkers.

The purpose of this study is to determine if the calcitriol absorption in pediatric subjects is comparable to that in adults and adolescents, with no significant impact on calcium/phosphorus metabolism.

The purpose of this study is to determine the relationship between two types of cell signals, type I interferon (IFN) and tumor necrosis factor (TNF), in psoriatic skin prior to and during treatment with etanercept and correlate that information with the degree of the improvement in the psoriasis.

Dendritic cells are a key component of the inflammatory response seen in psoriasis. Several current psoriasis therapies have been shown to reduce the number of dendritic cells in patients with psoriasis, leading researchers to believe that therapies specifically targeting dendritic cells may lead to improvement in psoriasis. Research recently conducted in Dr. Gallo's lab at the University of California San Diego has shown that transgenic mice overexpressing the enzyme hyaluronidase have a significant decrease in the number of dendritic cells in the dermal component of their skin compared to wild type mice. If hyaluronidase overexpression in humans also decreases the number of dendritic cells in the dermis, then hyaluronidase therapy may improve the clinical presentation of psoriasis. In order to test this hypothesis, recombinant human hyaluronidase (Hylenex®) will be injected subcutaneously below a psoriatic plaque in human psoriasis patients every week for a total of 4 weeks. Each week the clinical appearance of the plaque will be documented. At the final visit skin biopsies of the treated plaque will be taken to visualize the histology of the plaque and look for changes in expression of different inflammatory markers.

This is a multi-center, open-label study to evaluate whether participants follow the duration of use instructions for short-term use of alclometasone dipropionate in a population of participants with itchy skin conditions who would use OTC treatments for relief. The study population will be composed of two different cohorts: chronic condition sufferers (eczema or psoriasis) and participants who suffer from occasional itchy skin experiences (such as poison ivy, oak, sumac, insect bites, or skin irritations due to jewelry, cosmetics, detergents, or soaps) where an anti-itch medication would be used.

The study will estimate the preference of rheumatoid arthritis (RA) and Plaque Psoriasis (PsO) patients who self inject etanercept for one of two experimental autoinjectors.
