Active clinical trials for "Arteritis"

The primary objective of the study is to evaluate the efficacy of mavrilimumab (KPL-301) versus placebo, co-administered with a 26-week corticosteroid taper, for maintaining sustained remission for 26 weeks in subjects with new onset or relapsing/refractory giant cell arteritis (GCA).

This study was designed to evaluate the efficacy and safety of secukinumab compared to placebo to maintain disease remission up to 28 weeks including corticosteroid tapering, as well as up to 1 year (52 weeks) in patients with newly diagnosed or relapsing giant cell arteritis (GCA) who were naïve to biological therapy.

The objective of this observational prospective cohort study is to assess if: temporal artery stiffness measurement by applanation tonometry may help predict a final diagnosis of new-onset GCA In patients with a diagnosis of GCA, identify if temporal artery stiffness measured by applanation tonometry improves with treatment.

Takayasu's arteritis(TAK) is a rare systemic vasculitis which can cause ischemia or inflammation of the involved organs and increase the overall mortality rate.The traditional treatment of TAK is primarily empirical. The most commonly used drugs for treating active TAK are glucocorticosteroids(GC) and immunosuppressants. However, the genital toxicity of CYC has limited its long term use. In a pilot study carried out by the principal investigator of this study has shown that mycophenolate mofetil(MMF) combined with MTX is effective and with few adverse effects. The purpose of this prospective open-label study is to compare the efficacy and safety of GC+MMF+MTX with GC+CYC followed by GC+AZA for the treatment of active TAK. 150 patients with active TAK will be recruited and randomized in a 2:1 ratio to GC+MMF+MTX group and C+CYC and AZA group. Patients were followed for 52 weeks for efficacy and safety assessment.

Giant-cell arteritis (GCA) is an immune-mediated disease that mostly affects people older than 50 years of age. Glucocorticoid (GC) treatment dramatically alters the symptoms and course of GCA, reducing the likelihood of vascular complications that could lead e.g. to blindness. However, relapses usually occur when GC dosages are tapered, resulting in frequent re-treatment with high cumulative dosages of GC over time with substantial toxicity and morbidity (e.g. diabetes mellitus, infections, enhanced cardiovascular risk, osteoporotic fractures, cataracts). Therefore, novel therapies are needed that effectively reduce the dose and duration of GC treatment and provide more durable remissions of GCA. Tocilizumab (TCZ) is a humanized monoclonal antibody directed against the human interleukin-6 receptor (IL-6R). Elevated tissue and serum levels of IL-6 have been implicated in giant cell arteritis. Inhibition of IL-6 and/or its receptor therefore represents a new and novel approach for the treatment of RA. The primary endpoint is the proportion of patients that have achieved complete remission of disease after treatment with TCZ compared to treatment with placebo at week 12. All patients will receive glucocorticoids in a standardized form.

This is an open-label pilot study of tocilizumab (TCZ) 162 mg weekly administered subcutaneously for 52 weeks in combination with 8 weeks of oral prednisone.

It has been reported that around 40% of GCA patients are able to decrease the prednisone dose until 0.1 mg/Kg/d or less after 6 months of treatment. In this study, we hypothesized that adding 3 months of tocilizumab to prednisone could increase the percentage from 40 to 70%.

This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of tocilizumab in participants with GCA. The study will consist of 2 parts: a 52-week double-blind treatment period (Part 1) followed by a 104-week open label long-term follow-up period (Part 2). In Part 1 of the study eligible participants will be randomized to receive either tocilizumab every week (qw) or every 2 weeks (q2w) or placebo for 52 weeks, with tapering oral daily doses of prednisone. After Week 52, participants in remission will stop study treatment and enter long-term follow-up, whereas participants with disease activity or flares will receive open-label tocilizumab or other treatment at the discretion of the investigator for a maximum period of 104 weeks.

First-line tocilizumab treatment during 6 months could permit rapid steroid-tapering and induction of remission in Takayasu arteritis (TA).

When medical treatments fail, critical ischemia of the lower limb often leads to surgery, i.e. above knee femoro popliteal bypass. This bypass can be performed either with DACRON or PTFE prosthesis or with the autologous saphenous vein. Both technics are used but they have not been compared regarding bypass permeability and limb salvage. Thus, this study will compare the permeability rate of above knee femoro popliteal surgery whether performed with autologous vein versus prosthesis
