Filter by: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).
The aim of this study is to compare the use of FDG PET/CT to Ga-68 HA-DOTATATE (abbreviated DOTATATE) PET/CT in patients with active giant cell arteritis (GCA) started on prednisone to understand if DOTATATE can identify more areas of active blood vessel inflammation than FDG.
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 aim of this project is to prospectively evaluate the diagnostic accuracy of different imaging tools in specific giant cell arteritis disease subsets before and after treatment initiation. Diagnostic tools with high sensitivity and specificity are a prerequisite for optimal treatment of GCA patients. Specifically, the diagnostic accuracy of ultrasound (US) as compared to 18F-FDG PET/CT in new-onset, treatment naïve large vessel(LV)-GCA patients is investigated. Furthermore, long-term follow up including US, 18F-FDG PET/CT and cross sectional imaging is performed to explore the potential of imaging as monitoring and prognostic tools. In this observational cohort, the diagnostic accuracy of 18F-FDG PET/CT after three and ten days of glucocorticoid treatment in the subset of LV-GCA patients and the diagnostic accuracy of 18F-FDG PET/CT in cranial artery inflammation in new-onset, treatment naïve c-GCA patients as compared to a control group of patients with a previous diagnosis of malignant melanoma was also evaluated and is registered elsewhere (ClinicalTrials.gov Identifier: NCT03285945 and NCT03409913, respectively)
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.
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.
This study consists of two periods. The objective of Period 1 is to evaluate the efficacy of upadacitinib in combination with a 26-week corticosteroid (CS) taper regimen compared to placebo in combination with a 52-week CS taper regimen, as measured by the proportion of participants in sustained remission at Week 52, and to assess the safety and tolerability of upadacitinib in participants with giant cell arteritis (GCA). The objective of period 2 is to evaluate the safety and efficacy of continuing versus withdrawing upadacitinib in maintaining remission in participants who achieved sustained remission in Period 1.
Giant cell arteritis (GCA) is the most common form of vasculitis after age 50. It is a vasculitis affecting the large vessels, in particular the aorta and its collateral vessels, especially those in the external carotid area. Corticosteroids are the cornerstone of GCA treatment. They are very effective but are generally continued for 18 to 24 months or more since at least 30% of patients with GCA will relapse during their follow-up. Thus, the vast majority of patients treated for GCA have at least one adverse event from corticosteroid therapy, which is the main source of morbidity in these elderly patients. Reducing the use of corticosteroids, especially during relapses, is therefore a major objective to improve the treatment of patients with GCA. Methotrexate, abatacept and tocilizumab have been shown to be effective during GCA. However, the therapeutic effect of the first two is modest. As for tocilizumab, its use has many limitations: suspensive effect, many contraindications and there are no biological parameters available for reliable monitoring of inflammatory syndrome in these patients. Recent data have shown the major role of T helper (Th) Th1 and Th17 T cells in the pathophysiology of GCA. Th17 lymphocytes are sensitive to corticosteroid therapy but Th1 persists despite treatment and produces interferon-γ which activates macrophages and smooth muscle cells, leading to remodelling of the vascular wall responsible for ischemic GCA manifestations. Joint targeting of Th17 and Th1 responses is therefore necessary to fully treat the vascular inflammation that exists during GCA. Ustekinumab, which is a monoclonal antibody blocking the subunit common to IL-12 and IL-23 (p40), blocks the Th1 and Th17 responses, and could therefore be an excellent treatment for GCA. This study aims to evaluate the efficacy of ustekinumab for the treatment of GCA relapses. Very little data is available on the use of ustekinumab during GCA. Recently, 14 patients with refractory GCA, defined as the occurrence of at least 2 relapses and the inability to reduce the prednisone dose below 10 mg/d, received ustekinumab treatment. No patients relapsed during treatment while the median dose of prednisone was reduced from 20 to 5 mg/d. Ustekinumab has also been used successfully in a patient with refractory GCA. Under treatment, the patient did not have a new relapse and the dose of prednisone was reduced. In addition, there was a major decrease in the percentages of circulating Th1 and Th17 lymphocytes. However, to date, no controlled studies have been conducted to confirm the efficacy of ustekinumab during GCA relapses. This guarantees the originality and innovation of this study.
The purpose of this study is to describe medical practices in patients with GCA in terms of patient journey, diagnostic methods and specific GCA treatments since diagnosis.
The purpose of this study is to explore the safety, tolerability and activity of Nivolumab, a PD-1 inhibitor, in cohorts of patients with autoimmune disease. Two cohorts of patients will be enrolled, based on autoimmune disease type. Patients will be screened within 28 days prior to the start of dosing. Eligible patients will be enrolled in either of the two cohorts. Patients will receive treatment every two weeks, in an outpatient setting. One cycle is a 28-day period, with Nivolumab given on days 1 and 15 of a 28-day cycle. Subjects will be permitted to continue treatment beyond initial RECIST 1.1.
