Active clinical trials for "Psoriasis"

This is a retrospective, multi-center observational cohort study. This study will be implemented first in Germany (approximately 50 sites), the United Kingdom (approximately 20 sites) and Sweden (approximately 25 sites), followed by a selected number of countries in Europe, depending on apremilast local availability. The design of this apremilast retrospective study aims to provide clinical information regarding the treatment initiation and outcomes in psoriasis patients when prescribed apremilast in real world settings. In addition, this study is aiming at capturing physicians' and patients' treatment goals when initiating apremilast and whether these goals are achieved following apremilast use. This study is primarily descriptive in nature, and no a priori hypotheses are specified. Patients must voluntarily sign an informed consent form, be 18 or over, have been diagnosed with plaque psoriasis and have been treated with apremilast during the previous 5-7 months to participate in this study. They must not be involved in any other clinical study involving apremilast.

This study is being done to learn more about a less common "type" of psoriasis, called palmoplantar pustulosis (PPP). The majority of the current treatments used for this type of psoriasis have only a moderate effect on PPP. Thus, the investigators believe that PPP may be a different disease entity altogether, requiring different therapies. As such, the investigators hope to discover an immune signature for this condition. An immune "signature" is the unique way in which the combination of genes, cells, and proteins of the immune system work for each person. Because both psoriasis and the type of psoriasis patients have been diagnosed with, PPP, are conditions of abnormal immune system function, it is important to understand the overall function of the immune system in this condition (that is, find the immune "signature"). This study should help identify an immune system "signature" in people with PPP. The investigators have a laboratory technology which allows them to read the genetic "signatures" of a person's blood cells. Genes contain the instructions for making living things. Genes are contained in the cells' DNA (deoxyribonucleic acid). Most DNA is the same among humans, but the small differences people have in their DNA may explain why people develop different diseases. DNA and the genes it contains help produce RNA (ribonucleic acid), which in turn helps make proteins in people's cells. Differences in the types of proteins and the amount of those different proteins people's cells produce can affect a person's immune system. To help the investigators determine the immune "signature" in PPP, they will be examining the different genes, cells, and proteins that are active in patients with PPP versus patients who do not have the condition. The investigators will examine these genes, cells, and proteins in skin (through a skin sample) and in blood (through a blood draw). The goal is to develop new treatments for this skin condition. To do this, the investigators need to compare the skin and blood of patients with this particular type of psoriasis to the samples of healthy patients.

The purpose of this non-interventional, multicenter, post-marketing observational study (PMOS) was to assess rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), plaque psoriasis (PS), Crohn's disease (CD) and ulcerative colitis (UC) patients' adherence attitudes (beliefs) to maintenance therapy with adalimumab monotherapy or combination therapy with methotrexate (in participants with RA) and to investigate whether there were correlations between such beliefs and adherence to maintenance treatment.

This study is health economic analysis of medicinal treatment options for moderate-to-severe psoriasis vulgaris from the societal perspective. Efficacy data and other clinical outcomes will be derived from an up-to-date meta-analysis of randomized clinical trials (RCTs) for moderate-to-severe psoriasis. Direct and indirect costs will be extracted from various different sources, including summary of product characteristics (SPCs) and the German S3 guideline on psoriasis care, health care utilization data and official statistics. The study aims to investigate the comparative cost-effectiveness of biologic and conventional systemic treatments currently (as of June 1st, 2012) approved for moderate-to-severe plaque-type psoriasis in Germany. Effectiveness will be measured by means of the pooled (Psoriasis Area and Severity Index) PASI-75 response rates as reported in RCTs Direct cost as well as indirect cost will be considered.

The purpose of this study is to determine how patients use ustekinumab (label-recommended or other/missed dose interval) in Asia-Pacific countries.

Psoriasis vulgaris is no longer considered as a chronic inflammatory disease restricted to the skin. Evidence has accumulated in the past that psoriasis is a chronic inflammatory systemic disease. As in rheumatoid arthritis, the chronic inflammatory process plays a central role in the pathogenesis of associated comorbidities such as diabetes and cardiovascular disease. Since several years the armamentarium of psoriasis treatment has been broadened by the availability of TNF alpha blockers. These neutralize systemic TNF alpha which not only plays a central role in the pathogenesis of psoriasis but has also been linked to inflammatory pathways in diabetes and cardiovascular disease. While a few studies have investigated the positive effects of TNF alpha blockers on associated cardiovascular disease in rheumatoid arthritis patients, no research data exist on the effects of these therapeutic agents in patients with moderate to severe chronic plaque psoriasis. The present study aims at determining the effects of adalimumab, a potent and frequently prescribed TNF alpha blocker for the treatment of psoriasis, on different diabetic and cardiovascular risk factors in patients receiving this treatment as a remedy for moderate to severe plaque type psoriasis. The study is designed to explore whether adalimumab is capable to prevent or modulate psoriasis-associated comorbidities by blocking systemic inflammation. The effects of adalimumab will be compared with those of fumaric acids, which represent an established traditional systemic treatment option for moderate to severe psoriasis. Study hypothesis: Therapy with adalimumab will lead to an improvement of several parameters that reflect the risk for diabetes and cardiovascular disease in patients with chronic plaque psoriasis due to chronic inflammation. Endothelial dysfunction, as assessed by ultrasound flow mediated dilatation, will serve as primary outcome measure. Other risk factors such as blood lipids, hsCRP, IL-6, endothelial adhesion molecules, parameters of glucose metabolism and carotid intima-media thickness will be secondary outcomes. Aim: If adalimumab and/or fumaric acids will show a significant impact on the above mentioned parameters, these findings would offer a new perspective for the long term management of psoriatic patients and their comorbidities. Study design: Randomized, prospective, controlled, parallel group study Study population: 66 patients

The survey will be conducted with regard to the following aspects of treatment with Humira (adalimumab) in patients with psoriasis vulgaris and psoriatic arthritis receiving this drug: unknown adverse drug reactions, especially clinically significant adverse reactions incidence and conditions of occurrence of adverse reactions in the clinical setting factors that may affect the safety and effectiveness of Humira.

The purpose of this study is to evaluate the effectiveness and safety of adalimumab as used in routine clinical practice in adult patients with moderate to severe chronic plaque psoriasis in Spain.

Tachyphylaxis occurs when a medication is applied multiple times and a decreased response takes place. Many dermatologists believe that tachyphylaxis to topical steroids commonly occur. Other believe that tachyphylaxis can be explain by patient non-compliance with topical medications. This study is looking to prove or disprove the phenomenon of tachyphylaxis by using topical steroids in the psoriasis patient population. The investigators are looking to enroll 10 patients with symmetric, bilateral, and small psoriasis plaques. The investigators will either apply a strong topical steroid or a vehicle ointment to the plaques, which is be occluded with a band aid for a one week period. Weekly, the investigators will inspect the plaques for tachyphylaxis. This regimen will be repeated during phase 2, to see if there is change in the time to tachyphylaxis. This regimen will be repeated during phase 3, however, both plaques will be treated with steroid in this phase, and time to tachyphylaxis will be measured.

The purpose of the study is to compare the 3 ointment formulations containing LEO 29102 plus calcipotriol and Daivonex® ointment and Diprosone® ointment and to compare LEO 29102 plus calcipotriol to LEO 29102 alone and to calcipotriol alone in the same ointment vehicle, using the psoriasis plaque test modified from the method developed by KJ Dumas and JR Scholtz.
