Active clinical trials for "Psoriasis"

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.

The purpose of this study is to investigate the association between trough serum levels of etanercept, antibodies towards etanercept and its effectiveness in psoriasis patients.

The purpose of the study is to develop a database containing patient-reported information that may be used to understand and to increase awareness of the impact that moderate-to-severe plaque psoriasis can have on both daily life and life in general from a patient's perspective. The database will include self-reported patient narratives on the topic of the experience of having moderate-to-severe plaque psoriasis and will include information on treatments received, as well as de-identified clinical photographs taken over the course of the disease.

The expertise in the characterization of transcriptomics profile in lesional psoriatic skin and on the availability of innovative therapy for these patients.The investigators propose to follow the modification of the skin transcriptomics profile in psoriatic patients during successful Adalimumab biotherapy. Skin transcriptomics profiles of normal skin, psoriatic non lesional skin, and psoriatic lesional skin before and after biotherapy will be compared. The investigators will focus on the modification of the cytokine "signature" in these skin lesions and of some markers of keratinocyte inflammation. The modification of the transcriptomics profile induced by the biotherapy will be correlated to the clinical response Psoriasis Area and Severity Index.

Psoriasis is a chronic, debilitating skin disorder with an estimated prevalence of 2%. Psoriatic skin lesions start with initial pinhead-sized macules and then coalesce into plaques of varying sizes. Despite the great strides in the studies for psoriasis, it is still unclear why psoriatic skin lesions start with small macules and then spread peripherally. To study peripheral spreading of psoriasis, investigators plan to study small plaque psoriasis in comparison to large plaque psoriasis in the Korean population. Large plaque psoriasis is the most common form of psoriasis, seen in approximately 90% of all psoriasis participants. Large psoriatic plaques are >5 cm in size and localize to the extensor aspects of the elbows, knees, scalp, and genital area. On the other hand, small plaque psoriasis is the common or typical form of psoriasis that occurs particularly in Korea and other Asian countries. Korean small plaque psoriasis, even when chronic, remains <2 cm in size and is widely distributed on the upper trunk and proximal extremities. Investigators hypothesize that the expression of immune-related genes are different between small and large plaque psoriasis. The study of a genetically homogeneous cohort, characterized by the relatively high prevalence of small plaque psoriasis in the Korean population, may filter out spurious signals while allowing for significant associations to emerge from a relatively low number of participants. By comparing small and large plaque psoriasis, it is expected this study could lead to new understandings of the mechanisms involved in spreading of psoriatic plaques and provide new insights into psoriasis development.

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

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 the level of agreement between QuantiFeron -TB Gold test (QFT-G)and Tubeculin skin test (TST)for screening of latent tuberculosis in patients suffering from psoriasis.

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.
