Active clinical trials for "Psoriasis"

Psoriasis is a chronic skin disorder with a prevalence of approximately 1-3% worldwide. At present, there is no curative therapy available and the clinical course is unpredictable, but in the majority of cases psoriasis is a chronically remitting and relapsing disease. Several clinical subtypes of psoriasis exist with differences in manifestations and skin areas involved. Chronic stable plaque psoriasis (Psoriasis Vulgaris) is the commonest form of the disease, accounting for 85-90% of cases. The circumscribed infiltrated skin lesions are scaly and erythematous and often symmetrically distributed over the body. Several types of palliative therapies exist. The therapies are either topical or systemic. The severity of chronic plaque psoriasis is often determined by the percentage of body surface area (BSA) involved. For mild, moderate and severe chronic plaque psoriasis with BSA involvement of up to 20%, initial therapy is topical. Phototherapy and numerous systemic therapies are usually indicated when more than 20% of skin is affected. Severe plaque-type psoriasis requires systemic and long-term therapy in order to induce and maintain remission. Acitretin 25mg/day combined with a phototherapy regimen is a standard treatment that provides clinically significant efficacy, however many patients experience tolerability issues due to retinoid-related adverse events. Retinoid-related adverse events include but are not limited to: alopecia, dry mucus membranes, pruritus, photosensitivity, elevation of liver enzymes, elevation of serum triglycerides, cholesterol and decrease of HDL, arthralgias, myalgias, eye irritation, blepharitis, photophobia, conjunctivitis, headaches, nausea, anemia and leukemia. Reducing the acitretin dose from 25mg/day to 17.5mg/day may provide improved tolerability without compromising efficacy. The purpose of this study is to ascertain if reducing the acitretin dose from 25mg/day to 17.5mg/day will provide improved tolerability without compromising efficacy.

Topical corticosteroids are largely used in dermatology. The major problem related to their use is that the same mechanisms underlying their therapeutic effects (antiinflammatory and antiproliferative) may lead to adverse events. Conditions sensitive to corticosteroids require formulations with mild to moderate potency while high-potency corticosteroids era required in less responsive conditions. The aim of the present study is to compare the safety and efficacy of prednisolone acetate 0.5% cream (mild-potency non-fluoridated corticosteroid) versus betamethasone valerate 0.1% cream (high-potency fluoridated corticosteroid) in the treatment of mild to moderate cortisosensitive dermatosis (atopic dermatitis, contact dermatitis, seborrheic dermatitis and psoriasis). The study hypothesis is that 0.5% prednisolone cream will be as effective as 0.1% betamethasone cream and will be an alternative option to treat corticosensitive dermatosis in body areas where the use of fluoridated corticosteroids is contraindicated, such as the face.

Exploration of antipsoriatic effects of UVB-therapy +/- CYP-inhibitor Ketokonazol on affected psoriatic skin

RESTORE is an observational, open-label, multi-center, prospective, study enrolling Raptiva® (efalizumab) treated patients with moderate to severe chronic plaque psoriasis. The overall duration of the study is approximately 4 years. Patients will be followed from the time of study enrolment to study/treatment termination; thus active follow-up period will vary across subjects. Raptiva® (efalizumab)treated patients with moderate to severe chronic plaque psoriasis and meeting the inclusion/exclusion criteria specified will be eligible for participation in this study. Objectives: To document and quantify the incidences of adverse events in this patient population To explore the association of psoriasis treatments with changes in patient outcomes, quality of life, and treatment compliance.

Psoriasis is an immuno-mediated skin disorder, which affects about 2-3% of the population worldwide. For moderate-severe forms of psoriasis systemic immunosuppression is the treatment of choice. This clinical trial was initiated to compare the safety and effectiveness of mycophenolate mofetil and cyclosporine A for the treatment of psoriasis. Patients are randomized to receive either 2.5 mg/kg BW cyclosporine A or 1 g bid mycophenolate mofetil. If after six weeks no decrease in the PASI score occures cyclosporine A doses are increased to 5 mg/kg BW for additional six weeks. In the other arm mycophenolate mofetil is increased to 1 g tid for additional six weeks.

Psoriasis and metabolic disorders are well-known mutual comorbidities. The investigators hypothesized metformin can ameliorate both psoriasis and metabolic disorders mainly via gut microbiota modulation. The investigators design a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of treatment of metformin for psoriasis combined with disorders of glucose and lipid metabolism and to explore the role of gut microbiota during the process.

To compare the results of vitamin D plus UVB in treatment of psoriasis vulgaris with the results of UVB alone to study the relation between serum vitamin D and PASI score before and after treatment.

This study was designed as a multicenter, randomized, single blinded and placebo-controlled clinical trial. The aim of the study is to evaluate the clinical efficacy, safety and control of recurrence rate of plaque psoriasis with blood stasis syndrome, after treated with fire needle therapy.

To evaluate the effect and safety of treatment of psoriasis by human umbilical cord-derived mesenchymal stem cel

This is a 12-week treatment, singlecenter, open-label, single-arm, dose-selection, proof of concept study to determine a dosage of HSP 90 inhibitor (CUDC-305) that is tolerable and demonstrates preliminary efficacy for use in future efficacy Phase 2 trials. Male or female subjects aged 18 years or older with moderate to severe plaque psoriasis will be included in this study. Objectives are to determine the efficacy, safety and tolerability of CUDC-305 in patients with moderate to severe psoriasis.
