October 23, 2018 updated by: AstraZeneca

A Multicenter, Randomized, Double-blind, Parallel Group, Placebo-controlled, Phase 3b Study to Evaluate the Potential Effect of Benralizumab on the Humoral Immune Response to the Seasonal Influenza Vaccination in Adolescent and Young Adult Patients With Severe Asthma.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is designed to investigate the potential effect of benralizumab on the antibody response to the seasonal influenza virus vaccine in patients 12-21 years of age with asthma. Benralizumab will be given subcutaneously (SC) at Weeks 0, 4, and 8 weeks, at which time benralizumab levels will reach steady state. Patients will then receive 1 dose of intramuscular (IM) seasonal influenza virus vaccine at Week 8 and samples drawn at Week 8 and Week 12 to measure the antibody response to the influenza virus

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years to 21 years (Child, Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Postdose Strain-specific Hemagglutination-inhibition (HAI) Antibody Geometric Mean Fold Rise From Week 8 to Week 12
Time Frame: 4 weeks
To compare the geometric mean fold rises in influenza strain-specific hemagglutination-inhibition responses from Week 8 to Week 12 between patients receiving benralizumab 30mg and patients receiving placebo. Geometric mean fold rise was defined as antilog(z) (mean [log(z) x]), where "x" is the postdose HAI antibody titer fold rise from Week 8 and "z" is the natural logarithm.
4 weeks
Postdose Strain-specific Hemagglutination-inhibition Antibody Geometric Mean Titers Obtained at Week 12
Time Frame: 12 weeks
To compare the geometric mean titers of hemagglutination-inhibition antibody as a measure of influenza strain-specific response at Week 12 between patients receiving benralizumab 30mg and patients receiving placebo.
12 weeks
Proportion of Patients Who Experienced a Strain-specific Postdose Antibody Response at Week 12 With Antibody Response Defined as a ≥4-fold Rise in Hemagglutination-inhibition Antibody Titer From Week 8 to Week 12
Time Frame: 4 weeks
To compare the proportions of patients experiencing influenza strain-specific responses as measured by ≥4-fold rises in hemagglutination-inhibition antibody titer from Week 8 to Week 12 between patients receiving benralizumab 30mg and patients receiving placebo.
4 weeks
Proportion of Patients Who Achieved a Strain-specific Postdose Hemagglutination-inhibition Antibody Titer ≥40 at Week 12
Time Frame: 12 weeks
To compare the proportions of patients experiencing influenza strain-specific responses as measured by ≥40-fold rises in hemagglutination-inhibition antibody titer at Week 12 between patients receiving benralizumab 30mg and patients receiving placebo.
12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion of Patients Who Achieved a Strain-specific Postdose Hemagglutination Inhibition Antibody Titre ≥320 at Week 12
Time Frame: 12 weeks
To compare the proportions of patients experiencing influenza strain-specific responses as measured by ≥320-fold rises in hemagglutination-inhibition antibody titer at Week 12 between patients receiving benralizumab 30mg and patients receiving placebo.
12 weeks
Postdose Strain-specific Microneutralization Antibody Geometric Mean Fold Rise From Week 8 to Week 12
Time Frame: 4 weeks
To compare the geometric mean fold rises in influenza strain-specific microneutralization antibody responses from Week 8 to Week 12 between patients receiving benralizumab 30mg and patients receiving placebo. Geometric mean fold rise was defined as antilog(z) (mean [log(z) x]), where "x" is the postdose microneutralization antibody titer fold rise from Week 8 and "z" is the natural logarithm.
4 weeks
Postdose Strain-specific Serum Microneutralization Antibody Geometric Mean Titers Obtained at Week 12
Time Frame: 12 weeks
To compare the geometric mean titers of microneutralization antibody as a measure of influenza strain-specific response at Week 12 between patients receiving benralizumab 30mg and patients receiving placebo.
12 weeks
Proportion of Patients Who Experience a Strain-specific Postdose Antibody Response at Week 12 With Antibody Response Defined as a ≥4-fold Rise in Microneutralization Antibody Titer From Week 8 to Week 12
Time Frame: 4 weeks
To compare the proportions of patients experiencing influenza strain-specific responses as measured by ≥4-fold rises in microneutralization antibody titer from Week 8 to Week 12 between patients receiving benralizumab 30mg and patients receiving placebo.
4 weeks
Change From Baseline in Mean Asthma Control Questionnaire 6 (ACQ-6) Score at Week 12
Time Frame: 12 weeks
To compare the change from baseline at Week 12 in mean ACQ-6 score between patients receiving benralizumab 30mg and patients receiving placebo. The ACQ-6 assesses asthma symptoms (nighttime waking, symptoms on waking, activity limitation, shortness of breath, wheezing, and short-acting β2 agonist use). Questions are weighted equally and scored from 0 (totally controlled) to 6 (severely uncontrolled). The mean ACQ-6 score is the mean of the responses to each question. Mean scores of ≤0.75 indicate well-controlled asthma, scores between 0.75 and ≤1.5 indicate partly controlled asthma, and a score >1.5 indicates not well controlled asthma
