Filter by:This is a 52-week, randomized, placebo-controlled, double-blind, parallel group, multicenter study of depemokimab in adults with uncontrolled HES receiving standard of care (SoC) therapy. The study will recruit patients with a confirmed diagnosis of HES and who are on stable HES therapy for at least 4 weeks prior to randomization (Visit 2). Eligible participants must have uncontrolled HES with a history of repeated flare (≥2 flares in the previous 12 months) and blood eosinophil count of ≥1,000 cells/ microliter (μL) during Screening. Historical HES flares are defined as documented HES-related worsening of clinical symptoms or blood eosinophil counts requiring an escalation in therapy. Participants who meet the inclusion and exclusion criteria will be randomized in a 2:1 ratio to receive either depemokimab or placebo while continuing their SoC HES therapy.
The purpose of this study is to investigate the efficacy and safety of mepolizumab in children and adolescents with hypereosinophilic syndrome (HES) who are receiving standard of care (SoC) therapy.
Reaching active aging makes it important to implement new methods affecting the biological age of a person. Biochemical parameters of a blood test are aging biomarkers that are ones of the most accessible for testing. We know that, with age, there is increase in levels of LDL, triglycerides, homocysteine and other biomarkers relating the body state. Methods of extracorporeal hemocorrection showed good results in this area. For instance, the use of plasmapheresis is very effective during prophylaxis, treatment and rehabilitation after various diseases/injuries. The main effects of plasmapheresis are related to removal of endo- and exotoxins, including products of lipid peroxidation, and to draining effect as a result of a heavy flow of interstitial fluid containing products of pathometabolism into the blood stream within concentration gradient (by "dynamic equilibrium" in concentration of different substances in intracellular, interstitial and intravascular compartments). These effects are also related to release of receptors, their sensitization to their own neurohumoral regulation mechanisms, to insulin, in particular (as consequences, lower glucose tolerance, lower substrate glycation).
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.
This is a multicentre, randomised, double-blind (DB), parallel-group, placebo-controlled, 24-week Phase III study to compare the efficacy and safety of benralizumab versus placebo administered by SC injection Q4W in patients with hypereosinophilic syndrome (HES). This study comprises 2 distinct periods (together defined as the 'main study'): A 24-week, DB treatment period, during which patients will be randomised to receive either benralizumab or placebo, in addition to their prior stable HES background therapy, and an open-label extension (OLE) period, during which all patients will receive benralizumab. Patients will continue to be recruited until approximately 38 patients have had their first HES worsening/flare during the DB treatment period at which point the data cut-off for the primary database lock (DBL) will occur. Treatment allocation will remain blinded until the primary DBL. After the study is unblinded for the primary analysis, patients and investigators will remain blinded to patients' individual treatment allocations until after the final patient completes the DB treatment period. The primary analysis will only include data from the DB treatment period of the study. A follow-up analysis will be performed once all patients have the opportunity to complete the 24-week DB treatment period. A patient must complete the 24-week DB treatment period on investigational product (IP) to be eligible to enter the OLE treatment period. The final DBL will occur after the last patient completes the OLE.
Unexplained chronic hypereosinophilia (HE) and hypereosinophilic syndromes (HES) are heterogeneous regarding the organ involvements (heart, lungs, skin, .. or none), the evolutionary profiles, the response to treatments. Underlying mechanisms are largely unknown and may associate genetic predisposing factors (germinal ? somatic?), environmental factors (alimentation, tobacco use, hormones, infections, ..) The COHESion study aims to study all clinical and biological characteristics of HE/HES patients and their evolutionary profiles, with a focus on genetic factors and the mechanisms supporting transitory or persistant chronic HE/HES (in absence of any well identified extrinsic trigger like drugs, parasitosis, ..)
This phase II trial studies how well ruxolitinib works in treating patients with hypereosinophilic syndrome or primary eosinophilic disorders.
The mandate of this MPN registry is to collect clinical information, including molecular results, from consenting patients with a variety of MPNs at different time points during the course of their disease.
Eosinophilia, defined by a blood eosinophil granulocytes rate greater than 500 / mm3, is frequently encountered in internal medicine. Its causes are varied: atopy, drug allergies, parasitic infections, autoimmune diseases and solid neoplasias. Over 200 etiologies have been reported, some difficult to diagnose and can be life-threatening Eosinophilia can be a diagnostic dilemma, as the etiologies are extensive and varied. The aim of this study is to assess the feasibility of a diagnostic approach based on a decision algorithm in a group of patients with eosinophilia. We assume that a procedure with a hierarchy of additional tests would increase the frequency of diagnosed cases while decreasing the time to diagnosis. This procedure defined by an algorithm would even reduce the number of tests necessary to reach a diagnosis.
