Active clinical trials for "Hypereosinophilic Syndrome"

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.

This phase II trial studies how well ruxolitinib works in treating patients with hypereosinophilic syndrome or primary eosinophilic disorders.

The purpose of this study is to evaluate the safety and efficacy of the tyrosine kinase inhibitor, imatinib mesylate (Gleevec ) in reducing peripheral blood eosinophilia in patients with the myeloid form of hypereosinophilic syndrome (HES). Patients with the hypereosinophilic syndrome who meet a set of criteria designed to select patients with the myeloid form of the disease, as well as patients without myeloid disease who are refractory to standard therapy for HES, will be admitted on this protocol. A thorough clinical evaluation will be performed with emphasis on potential sequelae of eosinophil-mediated tissue damage. A baseline bone marrow will be obtained to exclude leukemia or lymphoma and to assess the degree and nature of eosinophilopoiesis. Bone marrow, blood cells and/or serum will also be collected to test for the presence of a recently described mutation that is associated with imatinib-responsiveness in HES, and to provide reagents (such as DNA, RNA, and specific antibodies) and for use in the laboratory to address issues related to the mechanism of action of imatinib mesylate in HES. Imatinib mesylate will be initiated at a dose of 400 mg daily, the FDA-approved dose for the treatment of chronic myelogenous leukemia. In patients who demonstrate a complete clinical and hematologic response to imatinib therapy and who do not have life-threatening disease, the dose will be decreased gradually to 100mg daily and then discontinued. In order to minimize bone marrow suppression, other myelosuppressive agents will be tapered and discontinued during the first week of therapy with imatinib mesylate. Complete blood counts will be performed weekly for the first month and biweekly thereafter. Clinical assessments will be performed every three months to assess progression of end organ damage. In patients who demonstrate a complete clinical and hematologic response to imatinib therapy and who do not have life-threatening disease, the dose will be decreased gradually to 100 mg daily and then discontinued. In the event of clinical, hematologic or molecular relapse during the taper, the imatinib dose will be increased to a maximum of 600 mg daily to achieve a second remission. Laboratory monitoring will be performed as above except for molecular monitoring which will be monitored monthly if drug is discontinued or molecular relapse occurs. Once a stable dosing regimen is achieved for greater than or equal to 6 months in subjects who have undergone dose descalation or greater than or equal to 2 years in subjects receiving 300-400 mg of imatinib daily who did not qualify for dose de-escalation, the frequency of NIH visits and end organ assessments will be decreased to 6 months, with molecular monitoring every 3 months and monthly routine laboratory assessments.

This is a multicentre, randomised, double-blind (DB), parallel-group, placebo-controlled, 24-week Phase 3 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 prior stable HES background therapy, and an open-label (OLE) treatment period, during which all patients will receive benralizumab. Patients will not continue to be recruited after 47 patients have had their first HES worsening/flare.The primary database lock (DBL) will occur when at least 47 patients have had their first HES worsening/flare event and all randomised patients have been followed up for the 24-week DB treatment period. The target patient population is male and female patients 12 years of age and older with symptomatic active HES. Approximately 120 eligible patients will be randomised at a 1:1 ratio to receive either benralizumab or matching placebo

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.

This phase I/II trial studies the best dose of venetoclax when given together with azacitidine and pevonedistat and to see how well it works in treating patients with newly diagnosed acute myeloid leukemia. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Pevonedistat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine, venetoclax, and pevonedistat may work better in treating patients with acute myeloid leukemia.

Background: - Eosinophils are white blood cells that help fight infections. High eosinophil levels can damage people s organs, causing hypereosinophilic syndrome (HES). Researchers want to study if the drug benralizumab can help people with HES. Objective: - To test if benralizumab can safely decrease eosinophils in people with HES. Eligibility: - Adults age 18-65 who have been on stable HES therapy for at least 1 month but still have symptoms and high eosinophil levels. Design: Participants will be screened with medical history, physical exam, and urine and blood tests. They will take simple heart and lung tests. Participants will also have a bone marrow biopsy. A numbing medicine is injected into the outer covering of the bone. Then a needle is inserted into the bone. A fast suction movement takes bone marrow cells. Phase 1: Participants will randomly receive either the study drug or placebo as an injection. They will have daily visits for the next 3 days, then 4 weekly visits, and then 4 biweekly visits. Each time, they will have medical history, physical exam, blood tests, and a check of side effects. They will receive another dose of the study drug or placebo at 1 month and 2 months after the first injection. Phase 2 repeats the Phase 1 schedule. All participants will receive the study drug. At 1 visit, participants will also receive a vaccine. At 4 visits, they will repeat the heart and lung tests. They will also have one other bone marrow biopsy. After week 24, participants will receive the study drug either 6 times over 6 months or twice over 6 months.

Eosinophils are a type of white blood cell. Elevated eosinophil levels can damage the heart, nerves, and other organs, in the syndrome known as hypereosinophilic syndrome (HES). Some individuals have a hereditary form of HES known as familial eosinophilia (FE). More research on the causation and mechanisms of HES is needed in order to design more effective and less toxic therapies. This study will investigate FE and its genetic causes, damage mechanisms, and disease markers (such as blood test abnormalities). It will enroll approximately 50 individuals (both adults and children) from a previously studied family with FE. This is a long-term study of indefinite duration. Participants will undergo yearly clinical examinations including medical history, physical examination, bloodwork, EKG, echocardiogram, and pulmonary function tests, with additional or more frequent examinations and tests as required. In addition, participants will donate blood and tissue for research purposes. Both adult and child participants will donate blood. At the initial evaluation, adult participants will donate bone marrow. During the study, some adult participants will also undergo a limited number of leukaopheresis sessions, in which blood is donated from one arm, the blood is separated into red blood cells and other components, and the red blood cells are returned into the donor's other arm.

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.

This phase II trial studies how well eltrombopag olamine works in improving the recovery of platelet counts in older patients with Acute Myeloid Leukemia (AML) undergoing induction (the first treatment given for a disease) chemotherapy. Platelet counts recover more slowly in older patients, leading to risk of complications and the delay of post-remission therapy. Eltrombopag olamine may cause the body to make platelets after chemotherapy.
