Filter by:The purpose of this study is to demonstrate the efficacy and safety of subcutaneously (s.c.) administered secukinumab 300 mg in combination with glucocorticoid taper regimen compared to placebo in combination with glucocorticoid taper regimen, in adult patients with new onset of giant cell arteritis (GCA) who are in clinical remission and who are eligible for treatment with glucocorticoid-monotherapy as per current clinical practice and treatment guidelines for the targeted participant population, thereby supporting health technology assessments (HTAs) of secukinumab in Germany.
To determine the phenotype of patients having PMR symptoms and primary Sjogren syndrome (pSS), we used a French national call to identify patients combining both diseases and collected retrospective clinical and biological data.
Giant cell arteritis - Optimization of diagnostics
Giant cell arteritis (GCA) is the most common vasculitis in adults. The diagnosis of GCA is evoked by the association of clinical signs and biological anomalies (inflammatory syndrome) in patients over 50 years of age. On the other hand, starting a treatment implies being certain of the diagnosis which requires performing a temporal artery biopsy under local anesthesia. This examination is therefore an invasive procedure for patients whose sensitivity is not optimal. This is why imaging techniques (echo-Doppler or MRI of the temporal arteries) have been developed to look for signs of vasculitis without the need to perform a biopsy. However, these examinations lack sensitivity (=falsely concluding the absence of GCA) and specificity (=falsely concluding the presence of GCA). Recently, advances in imaging, and in particular positron emission tomography (PET), have made it possible to visualize the cephalic arteries, including the temporal artery. The aim of this study is therefore to evaluate the sensitivity and specificity of PET of the cephalic arteries for the diagnosis of GCA and to compare them with those of echo-Doppler and MRI of the temporal arteries.
Vasculitis occur when the body's immune system, rather than protecting the body, attacks blood vessels, causing injury to the vessel and the part of the body it supplies with blood. Vasculitis is rare, and there are a number of different types, which can affect both adults and children. We treat vasculitis with steroids and drugs aiming to damp down the activity of the immune system, but they often cause side effects. Some patients do not improve with this treatment, or cannot tolerate it and their vasculitis worsens; this is known as refractory vasculitis. Patients with refractory vasculitis are at high risk of health complications from the disease and its therapy and are in need of newer more effective treatments with fewer side effects. Biologics are drugs which are designed to precisely target parts of the immune system and may have fewer side effects. Biologics have been used for several years to treat vasculitis, particularly anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis or AAV. However, for many of the rarer types of vasculitis, and especially those vasculitis disease types that are not ANCA-associated, there is little information to support use of biologic therapies as effective treatments. The purpose of this trial is to find out whether biologics are effective and represent value for money for participants with refractory vasculitis. The trial will include patients with Non-ANCA-associated vasculitis (NAAV)
Tocilizumab and Sarilumab are first-line biological disease-modifying anti-rheumatic drug (bDMARD) which inhibits Interleukin 6 (IL-6) pathway through blockade of its receptor on the treatment of Rheumatoid Arthritis and other rheumatic diseases as Giant Cell Arteritis, Still's disease and Idiopathic Juvenile Arthritis. At present, there is a lack of evidence to recommend the treatment of one bDMARD over another. Seeking for genetic biomarkers to predict response to treatment could be key towards a personalized treatment strategy in rheumatology. The investigators aime to evaluate whether functional single nucleotide polymorphisms (SNPs) in the IL6R gene could predict response and/or toxicity in patients with rheumatic diseases treated with anti-IL-6 receptor drugs.
Giant cell arteritis (GCA) causes inflammation of the arteries and can lead to serious complications such as blindness, necessitating rapid diagnosis and treatment. Although older technology non-digital PET/CT scans are routinely used for the diagnosis of GCA in large arteries, they have not been able to reliably detect inflammation of the small arteries responsible for blindness. Recent technological advances have enabled PET/CT imaging of millimetric disease in the body, which are now able to resolve small arteries. In the proposed research study, patients who are suspected by their doctors to have GCA will undergo an ultrasound of the temporal arteries, and digital PET/CT scan after injection of radioactive glucose. Digital PET/CT scans will be interpreted for the presence of abnormal uptake in the large and small arteries, as well as for the presence of other causes of the patient's symptoms. The diagnostic accuracy of PET/CT and ultrasound will be evaluated with respect to an expert panel diagnosis of giant cell arteritis and compared. Results will be adjusted for lack of a perfect reference test using advanced statistics. The goal will be to see if digital PET/CT can become a single, integrated test to diagnose this disease.
Polymyalgia rheumatica (PMR) is an inflammatory disease causing shoulder, hip, and neck pain and stiffness, in adults aged 50 years or older. This study evaluates how safe and effective ABBV-154 is in participants with glucocorticoid-dependent PMR. Adverse events and change in disease activity will be assessed. ABBV-154 is an investigational drug being evaluated for the treatment of PMR. Participants will be randomized into 1 of 4 treatment groups or arms, each arm receiving a different treatment. There is a 1 in 4 chance that a participant will be assigned to placebo. Around 160 participants, of at least 50 years of age, with PMR will be enrolled in the study at approximately 95 sites worldwide. The study is compromised of a 52 week double-blind, placebo-controlled period and a follow-up visit 70 days after the last dose of the study drug. All participants will receive a glucocorticoid taper along with the assigned dose of ABBV-154 or placebo, subcutaneously (SC) every other week (eow). There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
This is a phase III study of efficacy and safety of secukinumab versus placebo, in combination with glucocorticoid taper regimen, in patients with giant cell arteritis (GCA)
A French multicenter randomised and placebo-controlled study recruiting patients who present neurovascular involvement related to GCA (> 60 years) with symptomatic (stroke) or asymptomatic forms. The aim of this study is to assess the efficacy of tocilizumab to induce complete remission of GCA with cerebrovascular involvement (clinical and biological) and absence of clinical and MRI ischemic stroke recurrence at 24 weeks.
