Filter by:The trial was designed as a single-center, randomized, double-blind, single-dose parallel controlled phase I study to evaluate the similarity of pharmacokinetics and safety of Meperizumab injection and NUCALA® in healthy male volunteers. The plan is to enroll 88 healthy subjects. After signing the written informed consent voluntarily, the subjects will undergo a series of examinations and information collection to determine whether they meet the inclusion criteria. The qualified subjects will be randomized and administered. Biological samples were collected and safety checked before and after administration according to protocol requirements. Adverse events occurred during the trial were collected, and the combination of drug use and non-drug treatment were asked and recorded in detail. When the 90% confidence interval of geometric mean ratio of the main pharmacokinetic parameters of Meperizumab injection and NUCALA® was within the range of 80.00%-125.00%, it was proved that the pharmacokinetic characteristics of the two were similar.
This study aims to investigate the efficacy and safety of depemokimab compared with mepolizumab in adults with relapsing or refractory EGPA receiving SoC therapy.
The purpose of this study is to compare mepolizumab-based regimen to conventional therapeutic strategy for remission induction in patients with Eosinophilic Granulomatosis with Polyangiitis.
The aim of this study is to identify the optimal maintenance therapy for granulomatosis with polyangiitis (GPA) by comparing the MTX (standard regimen) with Tofacitinib in terms of efficacy, i.e. in preventing relapses.
The purpose of this study is to identify the most promising therapeutic strategy for patients with granulomatosis with polyangiitis and inadequate response to standard of care therapy. It will evaluate the efficacy to induce remission of three different salvage strategies including: a combination of rituximab with addition of a conventional disease-modifying antirheumatic drugs (either methotrexate, azathioprine or mycophenolate mofetil, but preferentially methotrexate); tocilizumab; or abatacept.
Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as the Churg-Strauss syndrome, is a systemic necrotizing vasculitis that affects small and medium sized blood vessels. NUCALA® (mepolizumab 300 milligrams [mg], subcutaneous administration) was approved in Japan in 2018 for the treatment of EGPA in adult participants. This is a single-arm, multi-center, prospective, non-interventional study that aims to assess long-term (2 to 4 years) real-world safety and effectiveness of NUCALA. Approximately 120 participants who completed the NUCALA Post Marketing Surveillance (PMS) study (National Clinical Trial [NCT]03557060) will be enrolled in the study. NUCALA is a registered trademark of GlaxoSmithKline (GSK) group of companies.
Introduction: The etiology and therapy of eosinophilic lung diseases are still poorly understood. For individual forms of disease, such as eosinophilic asthma or eosinophilic granulomatosis with polyangiitis (EGPA), new therapeutic approaches exist that block the interleukin IL-5 or the IL-5 receptor. Eosinophilic manifestations of the respiratory tract can exclusively affect the lungs or occur as part of a systemic disease. The manifestations partially overlap and are clinically difficult to differentiate (e.g. eosinophilic asthma, Samter Triad, EGPA or hypereosinophilic syndrome (HES)). It is now known that blood eosinophil counts correlate with the level of eosinophils recruited to the airways. However, it is still unclear whether there is a blood eosinophilia without clinical relevance or whether there is a risk of organ damage (e.g. in HES). Hence, different subtypes of eosinophils with different polarization are discussed. Aim of the study: A registry of patients with eosinophilia and respiratory manifestation will be established at the University Hospital of Innsbruck. The course of disease will be evaluated prospectively in a non-interventional study. This study stands on three main clinical pillars with focus on further characterization of eosinophilic cells: 1. Patients will be included who switch from a previous application of the anti-IL5 antibody mepolizumab (production and administration of the injection from lyophysate through the doctor) to the pre-mixed pen (self-injection at home). 2. Furthermore, special focus is set on patients suffering from the so-called Samter Triad. In these patients, the control of asthma, nasal polyps and NSAID intolerance will be examined in an interdisciplinary fashion during the course of treatment. 3. Previous clinical studies at our Department indicate that some patients with severe eosinophilic asthma or Samter Triad could represent a mono-organic or limited manifestation of lymphoid HES. This hypothesis is tested by measuring additional chemokines, somatic mutations and FACS parameters in this subgroup to verify a clonal disease. In addition, translational research will differentiate resident and inflammatory eosinophilic granulocytes by FACS analysis and further characterize them by fluorescence microscopy, electron microscopy, gene chip analysis and lipidomics, in the above-mentioned diseases and in healthy controls, respectively. Patients and methods: All patients suffering from eosinophilia with pulmonary involvement who are diagnosed with eosinophilic asthma, EGPA, Samter Triad, HES, and eosinophilic pneumonia with signed consent are included in the prospective registry. Provided, that they are registered at the outpatient department of pneumology, ENT, haematology or allergology at the University Hospital Innsbruck. The investigators will collect laboratory analyses, lung function, imaging, bone marrow biopsies, ENT findings and allergological findings over the course of the study. Furthermore, additional blood tubes are collected during routine blood tests, which are used to identify and characterize subtypes of eosinophilic granulocytes. Risks for patients: No additional examinations, blood sampling or invasive measures are required for the patient. Thus, there is no additional risk for study participants. Risks for control subjects: In order to be able to compare our results with the healthy population, volunteer subjects are recruited. After consent has been given, a blood sample is taken. Despite the low risk, it is theoretically possible that blood sampling may be accompanied by non-severe complications (such as hematoma, infection). Benefits: The investigators expect new insights into phenotype and therapy of patients with eosinophilic manifestations of the respiratory tract.
The purpose of this study is to find out whether hydroxychloroquine, in addition to background treatments, reduces disease activity in patients with Anti-Neutrophilic Cytoplasmic Autoantibodies (ANCA) Vasculitis, a group of autoimmune diseases. Hydroxychloroquine and is an established, effective, safe and inexpensive therapy, widely used in other autoimmune diseases such as lupus and rheumatoid arthritis. The study is open to adults diagnosed with certain types of vasculitis, called Granulomatosis Polyangiitis (GPA), Microscopic Polyangiitis (MPA) or Eosinophilic Granulomatosis with Polyangiitis (EGPA). Participants will be eligible if they are treated with background medication to control their vasculitis disease and have a low level of disease activity as defined by a Birmingham Vasculitis Activity Score (BVAS) of greater than 3. Participants will be randomly placed in 1 of 2 groups. Both groups will be given background medication. One group will receive hydroxychloroquine and the other will receive placebo. Participants will be on treatment for 1 year. 76 ANCA Vasculitis participants will be recruited (38 in each treatment arm) from UK vasculitis specialist centres.
This prospective study will assess if 12 months of vitamin D3 (cholecalciferol) supplementation, in patients with AAV (GPA, MPA, and EGPA) who have deficient or insufficient 25(OH)D3 status at enrollment, correlates with improved disease activity and/or lower frequency of relapse (compared to historical data and a previously conducted cross sectional study (part I) that assessed vitamin D status in a cohort of similar patients).
Mechanistic study to assess whether dual B-cell immunotherapy by co-administration of rituximab and belimumab will result in improvements in biological endpoints, functional outcomes and clinical status compared to rituximab with placebo.
