Active clinical trials for "Hypereosinophilic Syndrome"

This randomized phase I trial studies the side effects of vaccine therapy in preventing cytomegalovirus (CMV) infection in patients with hematological malignancies undergoing donor stem cell transplant. Vaccines made from a tetanus-CMV peptide or antigen may help the body build an effective immune response and prevent or delay the recurrence of CMV infection in patients undergoing donor stem cell transplant for hematological malignancies.

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: 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). 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. 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.

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 is an open label study of mepolizumab 750 mg intravenous in those subjects who participated in study 100185 to evaluate the long term safety and efficacy of mepolizumab in subjects with hypereosinophilic syndrome. The study will also evaluate the optimal dosing frequency for clinical use, the effects on corticosteroid reduction, and decrease of signs and symptoms of Hypereosinophilic Syndrome.

The purpose of the trial is to determine the safety and efficacy of Gleevec" in idiopathic hypereosinophilic syndrome (HES) and to characterize the molecular basis for the therapeutic benefit of Gleevec" in HES.

This phase I trial is studying the side effects and the best dose of entinostat when given together with sorafenib tosylate in treating patients with advanced or metastatic solid tumors or refractory or relapsed acute myeloid leukemia. Entinostat and sorafenib tosylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

The objectives of the study are: Evaluation of the safety profile of imatinib mesylate in patients with idiopathic hypereosinophilic syndrome resistant or refractory to, or intolerant of, prednisone, hydroxyurea or interferon-alpha, or untreated patients carrying the Fip1L1-PDGFRA fusion protein. Evaluation of the efficacy of imatinib mesylate in patients with idiopathic hypereosinophilic syndrome Analysis of patient's blood samples for the detection of activated kinases.

This phase I trial is studying the side effects and best dose of flavopiridol in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, or chronic myelogenous leukemia. Drugs used in chemotherapy, such as flavopiridol, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.

This phase I trial studies the best dose of azacitidine and to see how well it works with mitoxantrone hydrochloride and etoposide in treating older patients with acute myeloid leukemia that has a lower chance of responding to treatment or higher risk of returning (poor prognosis). Drugs used in chemotherapy, such as azacitidine, mitoxantrone hydrochloride, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.

Drugs used in chemotherapy, such as idarubicin and cytarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Bevacizumab may stop the growth of cancer by stopping blood flow to the leukemic cells in the bone marrow. Giving idarubicin and cytarabine with bevacizumab may kill more cancer cells. It is not yet know whether giving idarubicin together with cytarabine is more effective with or without bevacizumab in treating acute myeloid leukemia. This randomized phase II trial is studying how well giving idarubicin and cytarabine together with bevacizumab works compared to idarubicin and cytarabine alone in treating patients with newly diagnosed acute myeloid leukemia
