Trial summary

Background: Hypereosinophilic syndrome (HES) is a disorder in which the body has too many eosinophils (a type of white blood cell). Too many eosinophils in HES can cause damage to the heart, nerves, or skin. Certain drugs can help lower eosinophil counts to prevent tissue damage. Read more about this study

About this study

Official title: Assessment of Glucocorticoid Responsiveness and Mechanisms of Resistance in Hypereosinophilic Syndromes

Background:

  • Hypereosinophilic syndrome (HES) is a disorder in which the body has too many eosinophils (a type of white blood cell). Too many eosinophils in HES can cause damage to the heart, nerves, or skin. Certain drugs can help lower eosinophil counts to prevent tissue damage. Corticosteroids, such as prednisone, are used for initial therapy in this disorder. Although most people respond to prednisone, some people develop side effects from it, or do not respond very well to treatment. Better ways of determining the dose to give could help to decide on the best therapy for HES.

Objectives:

  • To determine whether a single-dose of prednisone can be used to predict which people with hypereosinophilia respond to treatment.
  • To study lack of response to steroid treatment in people with HES.

Eligibility:

Inclusion criteria:

  • Individuals with hypereosinophilic syndrome with high eosinophil counts.
  • Individuals who are willing to have blood drawn before and after getting steroids.

Exclusion criteria:

  • Individuals who are on more than 10mg of prednisone (or similar drug)
  • Individuals with hypereosinophilic syndrome who are on other medications that could interfere with the study
  • Women who are pregnant or breast-feeding
  • Individuals who have a known gene mutation associated with chronic eosinophilic leukemia
  • Children less than 18 years old who weigh less than 48kg or 106lb

Design:

  • Participants will have a screening visit with a physical exam and medical history. Blood and urine samples will be collected.
  • Participants will have a single dose of the steroid prednisone by mouth in the morning. Blood samples will be collected 2, 4, 24 hours after this dose.
  • On the day after the steroid dose, participants will provide another blood sample in the morning.
  • Participants will start to take prednisone daily when they return home. Blood samples will be collected weekly at the participant s doctor s office. The dose of prednisone will be lowered depending on the weekly eosinophil count. We will try to get each person on the lowest dose of prednisone possible that will control the disorder. Participants who do not respond or have severe side effects will be taken off prednisone. Other treatments will be considered for people who do not respond to steroids. The goal is to evaluate the response to prednisone. Our research will try to figure out why some people do not respond to steroids. Most people will complete the study within 6 to 16 weeks, depending on their response to prednisone.
Read the detailed description

This study aims to develop a model to determine whether a single, oral, weight-based dose of glucocorticoid (GC) can predict clinical and biologic response to GC s over the long term in subjects with hypereosinophilic syndrome (HES). Subjects with FIP1L1/PDGFRalpha-negative HES, who are symptomatic with eosinophil count >1500/microL and receiving less than or equal to10 mg prednisone daily, will be enrolled. A single oral dose of prednisone (1 mg/kg rounded to the nearest 5mg) will be administered. Eosinophil count and various laboratory parameters will be assessed at 2 hours, 4 hours and 24 hours following prednisone administration (investigators will be blinded to the results of the eosinophil counts). The subjects will then begin GC therapy at 30 mg prednisone daily followed by a standardized taper. The lowest dose of GC at which symptoms and eosinophilia are controlled will be compared to the change in eosinophil count at 2, 4 and 24 hours post-challenge. Mechanisms and in vitro correlates of GC resistance will also be explored.

Steroid ChallengeOtherA single oral dose of prednisone (1 mg/kg rounded to the nearest 5mg) was administered to all participants.

    Measure Description (%): Percent of baseline AEC is defined as the Absolute Eosinophil Count at 24 hours divided by the Absolute Eosinophil Count at Baseline *100.

    Measured: 24 hours

  4. Participants With Glucocorticoid Responsiveness - Overlap HES Subtypes

    Participants with overlap hypereosinophilic syndromes that achieved glucocorticoid responsiveness, suboptimal responsiveness, or without response.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Feb 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Percent Change in Eosinophil Count After Glucocorticoid Challenge (time frame: 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01524536, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2022.
