Filter by:Patients with psoriasis seem to have increased risk for developing atherosclerosis. This may be due to the fact that psoriasis and atherosclerosis are both caused by inflammation and involvement of cells of the immune system. Atherosclerosis is frequently treated by statins (class of cholesterol lowering drugs), which lower bad cholesterol levels and also reduce inflammation. Some new evidences also suggest that therapy with statins may improve psoriasis skin disease. The current study aims are to evaluate whether a strong statin named Atorvastatin can improve psoriatic skin disease and functioning of the arteries. The study also aims to evaluate if the activity of these two diseases are related to levels of common inflammatory biomarkers (substance in blood) and whether Atorvastatin can change their levels.
The main aims of this study are to determine whether: a) psoriasis patients with or without arthritis have more cardiovascular inflammation than healthy subjects and b)3 months of etanercept (enbrel) therapy (prescribed to psoriasis patients with or without arthritis by their treating clinicians) will decrease cardiovascular inflammation.
The main objective of this study is to evaluate the long term safety of CP-690,550 in patients being treated for moderate to severe plaque psoriasis and/or psoriatic arthritis. This study will also to compare the efficacy of two oral doses of CP-690,550 (5 mg BID and 10 mg BID) after 16 weeks of treatment.
This study aims to see if patient quality of life can be approved after treatment with an injectable medication called ustekinumab for the treatment of generalized psoriasis. The investigators hypothesize that the investigators will see improvement in quality of life.
The purpose of this study is to assess the safety, tolerability, immunogenicity, and clinical effects of AMG 811 following single subcutaneous dose administration in subjects with moderate to severe psoriasis.
Background: Psoriasis is a chronic, immunologically-mediated, inflammatory skin disease and targeted therapies e.g. tumor necrosis factor (TNF)-α and TH-17 antagonists have become increasing important agents in the management of psoriasis. TNF, interleukin-17 (IL-17) and TH-17 play major roles in defense against infection. Large-scaled clinical trials and post-marking surveillance had shown these agents may increase susceptibility to infections. Most studies evaluate the reactivation of tuberculosis but the influence of targeted therapies on the viral infection has not been extensively investigated. TNF-α has been shown to contribute to the killing of cytomegalovirus (CMV)- and human papillomaviruses (HPV)-infected cells. Additionally, recent studies have shown a high prevalence of HPV DNA in psoriatic skin and increased HPV5 antibodies in patients with psoriasis. The prevalence of HPV in the skin was also affected by therapeutic modalities, such as psoralen-ultraviolet A (PUVA). Several case reports in which CMV, Epstein-Barr virus (EBV) and HPV infection complicated therapy with TNF-α antagonists have been reported. However, the study investigated the effect of TNF-α antagonists and other biologics on reactivation of latent viruses is limited. Only two studies investigated the short-term effect of infliximab on reaction of herpesviruses in patients of rheumatoid arthritis and Crohn's disease. The high prevalence of combination use of immunosuppressants, such as methotrexate alongside with TNF-α antagonists in these patients is different from patients with psoriasis. Additionally, various bacterium and fungi, such as Staphylococcus aureus, Malassezia are associated with provocation and/or exacerbation of psoriasis and recent studies had shown IL-17 is essential for the immune response to common fungus Candida albicans. Aim: The aim of this study is to prospectively investigate the effect of target therapies (TNF-α, TH-17 antagonist, IL-17 antagonists, tofacitinib and apremilast) on the activation of viruses, including CMV, EBV and HPV and the impact of biologics on the prevalence of surface colonization of microorganism, including HPV, bacteria and fungi, in patients with psoriasis. Methods and procedures: Our project consists of two related study. The first (Study 1), a prospective observational study, included patients with psoriasis who are going to undergo biologics therapy, the viral loads of CMV and EBV, HPV DNA detection in eyebrow hairs and skin scales, and bacterial, fungal cultures from skin scales were performed before the initiation, 12 and 24 weeks after initiation of the target therapies, 12 weeks after discontinuation of target therapies. This part of our project is to investigate the dynamic effect of biologics on the microorganisms in patients with psoriasis. The second part (Study 2), a case control study, recruits psoriasis patients who have started target therapies, they receive the sampling of blood, eyebrow hairs and skin scales for CMV, EBV and HPV investigations when they are enrolled. Control group compromised of age-and disease severity-matched psoriasis patients who are not treating with target therapies or other systemic antipsoriatic agents. Comparison of the prevalence of latent virus, virus reactivation, bacteria and fungi skin colonization between psoriasis patients who are treating with and without target therapies is performed. The aim of study 2 was to assess any difference of the status of latent virus or microorganism colonization in skins between psoriasis patients treated with and without target therapies.
The purpose of this study is to study the safety, tolerability and immunogenicity of AMG 557 following multiple subcutaneous dose administration in adults with moderate to severe psoriasis.
This is a dose-ranging study designed to investigate the efficacy and safety of Baricitinib in the treatment of participants with moderate to severe, chronic plaque psoriasis as assessed by the Psoriasis Area and Severity Index (PASI) score and routine safety assessments.
This is a randomized, placebo-controlled, ascending single dose study of KHK4827 to evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of subcutaneous or intravenous administration of KHK4827 in healthy male subjects or moderate to severe psoriasis patients.
The purpose of this study is to assess the safety and tolerability of CNTO 1959 following a single subcutaneous (SC, under the skin) dose administered to Japanese participants with moderate to severe plaque psoriasis.
