A Trial of Mepolizumab Adjunctive Therapy for the Prevention of Asthma Exacerbations in Urban Children (MUPPITS-2)
Mechanisms Underlying Asthma Exacerbations Prevented and Persistent With Immune-Based Therapy: A Systems Approach Phase 2 (ICAC-30)
Study Overview
Detailed Description
Asthma is a growing problem, especially in children. It causes frequent wheezing, shortness of breath, chest tightness, and cough. Asthma attacks, or exacerbations, are problems for children with asthma.
The purpose of this study is to see if treatment with a medication called mepolizumab (Nucala®), given along with standard asthma care, makes children less likely to have asthma attacks. Mepolizumab is a new drug that is approved by the Food and Drug Administration (FDA) for use in children with asthma who are aged 12 years and older. Mepolizumab is given by injection. It is being studied by other researchers in children aged 6-11 years.
All participants will be prescribed standard asthma medications by a clinician who is trained in asthma care. Medications will include controller medications, a rescue medication, and a medication for severe asthma attacks (prednisone). The amount of medication that participants receive may be increased or decreased during the study based on their symptoms and breathing test results. Study clinicians will treat all participants according to the same guidelines. These treatment guidelines are based on recommendations from a group of national experts in asthma. This study has been designed this way so that all participants will have safe and effective standard asthma care.
In order to enroll in this study, participants must be willing to have their asthma managed by the study clinician during the entire study period. Participants must also be willing to bring study medications to all study visits.
This study will include up to 20 study visits. Participant involvement in the study will endure for approximately 1 year.
During the treatment period, participants will be placed in one of two treatment groups:
- Mepolizumab injection and guidelines-based asthma care or
- Placebo injection and guidelines-based asthma care.
Participants will not be able to choose which group they are assigned. This assignment is random and by chance, much like flipping a coin. Participants will not know if they are receiving mepolizumab or placebo. Investigators will compare the study results between the participants of each group.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Asthma Exacerbations During the Treatment Period
Time Frame: Up to 12 months
|
Exacerbations were defined as a prescription of a course of systemic corticosteroids by a clinician, initiation of a course of systemic corticosteroids by a participant, or as a hospitalization for asthma.
If a participant initiated and completed a course of systemic corticosteroids without clinician involvement, this course was counted only if the study clinician agreed the treatment was warranted, and it met the following dosage: the course for prednisone, prednisolone, or methylprednisolone was at least 20 mg daily dose for 3 of 5 consecutive days.
The course for dexamethasone was at least a 10 mg single daily dose.
If a corticosteroid burst for the treatment of an asthma exacerbation was prescribed by a non-ICAC clinician, it was counted regardless of dose.

Up to 12 months

Measure Description |
Time Frame |
---|---|---|
Composite Asthma Severity Index (CASI)
Time Frame: Week 12, 24, 36, 48, 52 after randomization
|
Composite Asthma Severity Index (CASI) scores included 5 domains: day symptoms and albuterol use, night symptoms and albuterol use, controller treatment, lung function measures, and exacerbations.
The minimum composite score was 0 while the maximum was 20.
