Filter by:The purpose of this study is to assess the efficacy of a tocilizumab-based regimen compared with placebo on top of rapidly tapered glucocorticoid treatment in a double- blind, controlled fashion, focussing on glucocorticoid-free remission of disease.
Interleukin-6 (IL-6), a pro-inflammatory cytokine, has been found to have a crucial role in the pathogenesis of Giant cel arteritis (GCA). Based on this rationale, several recent studies demonstrated the efficacy of tocilizumab (TCZ), an anti-IL-6 targeted monoclonal antibody, for the treatment of patients with refractory GCA. Confirming previous reports,in a recent retrospective study the investigators successfully treated 10 patient with refractory GCA with TCZ. All patients achieved a complete disease remission evaluated by clinical, laboratory, and positron emission tomography (PET). In a considerable number of GCA patients treated with corticosteroids (CS) the therapy may be interrupted with no disease flares. No data are available on the management of patients achieving the remission with TCZ.
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.
To investigate the safety and efficacy of abatacept with steroid treatment in comparison to steroid treatment alone in up to a 28 week taper of steroid treatment to sustain remission of Giant Cell Arteritis in adults.
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.
The purpose of this study is to delineate the association of the 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (18F-FDG PET/CT) detected vasculitis pattern of the large vessels (PET positivity) and the clinical picture of Polymyalgia Rheumatica (PMR)/Giant Cell Arteritis (GCA) .
The purpose of this study is to collect existing tissue specimens from subjects enrolled in Vasculitis Clinical Research Consortium (VCRC) studies. Analysis of these tissue specimens and linked clinical data collected through VCRC studies may lead to the identification and development of a series of translational research projects. Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular diseases.
The purpose of this study is to determine whether ustekinumab is effective in the treatment of Giant Cell Arteritis (GCA)
Patients are treated with infusions of Tocilizumab (TCZ) or placebo for 5 months. Clinical evaluation is performed using PMR-AS. The PMR-AS is computed by summing the 5 variables after multiplying by 0.1 for weighting purposes: PMR-AS (activity scale = AS) = C reactive protein (CRP) (mg/dl) + patient scale (VASp) (0-10 scale) + physician scale (VASph) (0-10 scale) + morning stiffness(MST) [min]×0.1) + elevation of upper limbs (EUL) (0-3 scale). All the patients included are treated with glucocorticoid (GC).GC are reduced at each visit until the end of the study, depending on response to treatment and PMR-AS.
SYNOPSIS The giant cell arteritis (GCA) is the most frequent vasculitis in people over 50 years. Despite recent progress and physiopathogenic, corticosteroids remains the standard treatment for decades with a very good initial clinical efficacy but a high relapse rate (nearly 40% to 6,5 months) during its decay. This sensible population is particularly exposed to the side effects of corticosteroids, leading to think about savings strategies. But the association of immunosuppressive therapy and/or anti- TNFα has not demonstrated benefits in terms of efficiency or long-term tolerance to cumulative doses of prednisone. The responsibility of proinflammatory cytokines such as TNFα, IL- 6 and IL-1 has been studied in the pathogenesis of GCA in temporal artery walls and in mouse models. The primary pathogenic role of IL- 1 is based on the increase in serum or nuclear protein itself or that of its mRNA. The study of temporal artery biopsies has shown increased local production of IL- 1β mRNA, IL- 6 and TGFβ (indicative of macrophage activation ) and those of INFɣ and IL 2 (indicative of T lymphocyte activation). Recently, Ly et al (Ly KH JBS 2014) reported the efficacy of anakinra, a recombinant molecule of IL- 1RA specifically blocking the IL- 1 α/β, in three cases GCA refractory to conventional treatments. Here investigators propose a randomized, multicenter, controlled, double-blind study of anakinra against placebo in addition to corticosteroids in the treatment of GCA. This study will include 70 patients randomized equally in both arms: reference treatment (prednisone plus placebo) or the experimental treatment (prednisone + anakinra). Treatment with prednisone will be identical in the two arms, namely a dose of 0.7 mg/kg/day orally on day 1, followed by a progressive decrease in the dose pattern depending on the weight. In the experimental arm, dose of anakinra is the one usually used, ie 100 mg/day by subcutaneous injection from day 1 until the end of week 16 (S16). In the reference arm of the treatment, a placebo anakinra is associated with corticosteroid in the same packaging, duration and respecting the double-blind. Investigators thus hypothesized that the addition of anakinra to corticosteroid compared to placebo added to the latter, will show a significant decrease in GAC relapse rate. Indeed, the challenge of corticosteroid therapy in this disease is not so much a problem of initial effectiveness, than the adverse events related to relapses and steroid dependence.
