About this study

Official title: Mepolizumab As a Steroid Sparing Treatment Option in the Churg Strauss Syndrome

The purpose of this study is to determine whether Mepolizumab (a monoclonal antibody against interleukin-5) is a safe and well-tolerated therapy that will allow for steroid tapering in patients with steroid-dependent Churg-Strauss Syndrome (CSS).

Read the detailed description

Specific Aims:

  1. Document the safety of mepolizumab therapy in patients with CSS.
  2. Demonstrate the steroid sparing effect of mepolizumab therapy by decreasing corticosteroid dosage while using this anti-IL5 therapy.
  3. Demonstrate the efficacy of anti-IL5 therapy in improving the signs and symptoms of CSS by:
  4. Measuring serum markers of CSS disease activity, including: peripheral eosinophilia, erythrocyte sedimentation rate, anti- neutrophil cytoplasmic antigen, C-reactive protein and IgE levels.
  5. Assessing the activity level of vasculitis via the Birmingham Vasculitis Activity Score
  6. Evaluating asthmatic response via serial peak flow and FEV1 measurements as well as asthma symptom scores using the Juniper scale.
  7. Assessing changes in novel parameters such as fractional excretion of nitric oxide and IL-5 levels.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Indicated Side Effects

    Side effects experienced by participants 1 to 2 days after Mepolizumab infusion.

    Measured: Participants were followed for the duration of the study, approximately 44 weeks

  2. Number of Participants Who Experienced Specific Symptoms

    Number of participants who experienced specific symptoms during the trial.

    Measured: 44 weeks

Secondary outcomes (3)

  1. Steroid Dosing During Trial

    Measured: 20 weeks

  2. Evaluate Overall Positive Change in Churg-Strauss Syndrome Via the Measures Outlined in Study Aims

    The Asthma Control Questionnaire (ACQ) was one measure used to assess the prevalence of asthma symptoms the participant was having during the study. It is a series of 7 questions assessing how often, over the past two weeks, the participant wakes up from their asthma, how bad their symptoms were, etc. The greater the prevalence of symptoms, the higher the score. Each of the 7 questions is scored 0-6. The total score is calculated by adding the individual question scores and dividing the sum by 7.

    Measured: 20 weeks

  3. Efficacy- Exacerbation Rate

    Quantified the exacerbation rate (total number of exacerbations per day) of the participants during treatment with mepolizumab and without treatment. Exacerbations were characterized as any worsening of clinical disease requiring an increase of systemic corticosteroid therapy (e.g. prednisone) for asthma, respiratory symptoms, or underlying vasculitis.

    Measured: Treatment period (12 weeks)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Mepolizumab in people with Churg Strauss Syndrome, run by Brigham and Women's Hospital at 1 site in United States.

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

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. 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 22 Mar 2017. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 22 Mar 2017). 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?

Number of Participants With Indicated Side Effects (time frame: Participants were followed for the duration of the study, approximately 44 weeks). The study lists 2 primary outcomes in all. 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 NCT00527566, which also lists 7 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 22 Mar 2017; AzTrials last refreshed its copy on 8 Nov 2026.
