Filter by:IFN-gamma is a central player in the development of psoriasis lesions, which can be involved a variety of cellular processes in the skin. Dendritic cells are important cells in driving inflammation in psoriasis through the induction of T cells that produce IL-17 in psoriasis. Injecting IFN-g into the skin can increase the numbers of T cells and also inflammatory DCs that produce cytokines involved in IL-17 production. Thus, the investigators hypothesize that the dendritic cells present in the skin after IFN-g injection polarize IL-17-producing T cells.
Psoriatic Arthritis (PsA) is a comorbidity that affects a significant proportion of participants with moderate or severe psoriasis. The purpose of this study was to describe the profile of patients with moderate or severe plaque psoriasis (Ps) in Colombia and to evaluate adalimumab efficacy and safety profile.
To estimate the difference in effectiveness between treatment with etanercept 50 mg twice weekly (BIW) and treatment with etanercept 50 mg once weekly (QW) plus an as needed (PRN) topical agent for 12 weeks in adults with moderate to severe plaque psoriasis.
The main objective of this study is to compare the effects of CP-690,550 with the effects of placebo in patients being treated for moderate to severe chronic plaque psoriasis. This one-year study will also evaluate the safety and tolerability of CP-690,550 versus placebo.
This study is to evaluate the efficacy and safety of M518101 and the dose relationship among two doses of M518101 and placebo in male and female plaque psoriasis patients.
The purpose of this study is to determine whether AN2728 topical ointment is a safe and effective treatment for mild-to-moderate plaque-type psoriasis.
The purpose of this study is to evaluate the anti-psoriatic effect of LEO 27989 ointment and calcipotriol plus LEO 27989 ointment, using the psoriasis plaque test modified from the method developed by KJ Dumas and JR Scholtz.
The aim of the study is to intra-individually compare the dose-related efficacy of LAS41004 in a Psoriasis Plaque Test (PPT)
The purpose of this study is: To evaluate the efficacy of the drugs under study for treating chronic plaque psoriasis. - Population: 50 patients will be selected from both sexes, healthy, between 18 and 65 years with a clinical diagnosis of chronic plaque psoriasis with PASI <20%, according to the criteria of inclusion and exclusion.
This is a two-part study. The purpose of the pilot study (Part 1) is to optimize the acquisition, handling and shipping procedure for skin biopsies obtained from participants with plaque psoriasis. No treatment will be administered. Part 2 will include 2 cohorts. In Cohort 1, the effects of 16 weeks of treatment with either ustekinumab or etanercept on biomarkers in lesional skin in participants with moderate to severe psoriasis will be evaluated. In Cohort 2, biomarkers of lesional skin from participants with moderate to severe psoriasis who are not treated with biologic therapy will be evaluated over 16 weeks. The primary hypothesis is that treatment with ustekinumab reduces messenger RNA (mRNA) expression of genes in the interleukin 12 (IL-12) pathway that are modulated by interferon gamma (IFN-γ).
