Active clinical trials for "Arteritis"

This study will evaluate the pharmacokinetics, pharmacodynamics, and safety of two dose levels of tocilizumab (TCZ) administered by intravenous (IV) infusion every 4 weeks (Q4W) to participants with giant cell arteritis (GCA).

Cortico-dependence is frequent in giant cell arteritis patients, and no drugs has proved its ability to prevent corticodependence. Hydrocychloroquine is a well tolerated immunomodulatory drug that may have a corticosteroid sparing potential according to immuno-pharmacological and clinical data. We have designed a multcentric double blind versus placebo randomized controled trial to assess the corticosteroid sparing effect of hydroxychloroquine in non complicated giant cell arteritis.

Two recent RCTs showed the ability of tocilizumab to induce and maintain remission of giant cell arteritis. Both studies used the dosing schemes for Rheumatoid Arthritis (i.e. 8mg/kg bodyweight i.v. in 4-weekly intervals and 162mg weekly s.c., respectively). In both trials glucocorticoids (GC) were initially administrated at medium to high doses with subsequent rapid reduction and discontinuation over 24 weeks. In case of relapse, GC doses were re-increased. The results of both studies suggest that GC could be reduced more rapidly. This would further reduce GC-induced adverse effects. Thus, the investigators propose to perform an open label single arm study to assess the efficacy of ultra-short co-medication with GC, using Simon's minimax two-stage design.

The aim of this national pragmatic observational study is to investigate whether the use of new diagnostic imaging modalities facilitates disease stratification that can potentially predict treatment response, relapse risk and complications and hence guide management strategies to improve disease control and reduce disease and treatment related damage.

The main purposes of this study is to analyze, in a randomized controlled trial, the effects of an exercise-based cardiac rehabilitation program (i) on biomarkers of endothelial function, (ii) on biomarkers of inflammation, (iii) on autonomic function, and (iv) on arterial stiffness in coronary artery disease patients (CAD). Additionally, the investigators aim to analyze the (v) contribution of age and the changes in traditional risk factors to the modification of the endothelial dysfunction and inflammation, and (vi) the contribution of the changes in inflammatory and endothelial function biomarkers to the modification of autonomic function and arterial stiffness. The investigators hypothesize that exercise training will improve the autonomic function, arterial stiffness and mitigate the endothelial dysfunction and inflammation in CAD patients even in the absence of significant changes in traditional risk factors. Thus, the investigators expect with the present study to promote, develop and expand the knowledge in this field by assessing the impact of exercise on a pool of markers that provide a wide picture of the pathophysiological processes underlying CAD.

Giant cell arteritis (GCA) and Takayasu's arteritis (TAK) are diseases that cause swelling of the arteries in the head, neck, upper body, and arms. TAK specifically affects the aorta, the largest blood vessel in the body, and its branches. Therapies are available to improve the symptoms of GCA and TAK, but relapse often occurs, and better treatments are needed. Abatacept is a drug that interacts with certain cells in the body that are involved with GCA and TAK. This study will evaluate the effectiveness of abatacept in treating GCA and TAK and preventing disease relapse.

Hypothesis: In giant cell arteritis (GCA), a short initial treatment with anti-TNF may allow a faster decrease of steroids dosage and therefore avoid some of the adverse events of steroids.

Cardiovascular disease (CVD) represents the leading cause of death worldwide. While medications, such as statins, significantly reduce atherosclerotic CVD (ASCVD) risk by lowering low density lipoprotein levels, they may also have pleiotropic effects on inflammation. The immunomodulatory effects of these medications are relevant to ASCVD risk reduction given that inflammation plays a central role in atherosclerotic plaque formation (atherogenesis) and influences the development of vulnerable plaque morphology. Patients on statins, however, may have residual inflammation contributing to incident ASCVD despite the potent LDL-lowering effects of statins. While new therapies, such as proprotein convertase subtilisin/kexin type 9 (PSCK9) inhibitors, further reduce incident ASCVD and drastically reduce LDL-C below that achieved by statin therapy alone, PCSK9 inhibitors may also have pleiotropic effects on inflammation. Thus, PCSK9 inhibitors may help reduce arterial inflammation to a level closer to that of patients without ASCVD. This study will apply a novel targeted molecular imaging approach, technetium 99m (99mTc)-tilmanocept SPECT/CT, to determine if residual macrophage-specific arterial inflammation is present with statin therapy and the immunomodulatory effects of PSCK9 inhibition. Given the continued high mortality and morbidity attributable to ASCVD, strong imperatives exist to better understand the immunomodulatory effects of lipid lowering therapies and residual inflammatory risk. This understanding, in turn, will inform the development of new ASCVD preventative and treatment strategies as well as elucidate other indications for established therapies.

This study will evaluate the safety and effectiveness of baricitinib in the treatment of giant cell arteritis. All participants will be taking prednisone at the start of the study. The prednisone will be reduced according to a standardized tapering schedule while participants continue to take one tablet of baricitinib daily for 52 weeks.

This is a multicenter, interventional, open-label, long-term extension study of Study WA28119 (NCT01791153) to evaluate the long-term safety of SC tocilizumab in participants with GCA who subsequently have flare or persisting disease activity. A maximum of 11 participants from six centers in France that participated in the WA28119 study will be enrolled. The entire study duration is anticipated to be approximately 160 weeks.
