E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of brodalumab compared with placebo as measured by the change in asthma control (based on the Asthma Control Questionnaire [ACQ]) from baseline at week 24 in subjects with inadequately controlled asthma and high reversibility despite standard of care. |
|
E.2.2 | Secondary objectives of the trial |
Key Secondary Objectives:
To evaluate the effect of brodalumab compared to placebo at week 24 on:
• asthma exacerbations (event rate defined as the number of events per subject year)
• ACQ in inhaled corticosteroid (ICS)+long acting β-agonist (LABA) strata
• asthma exacerbations (event rate) in ICS+LABA strata |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Brodalumab Pharmacokinetic Substudy Objective: To characterize the pharmacokinetics of brodalumab
Biomarker development and pharmacogentic substudy (optional):
Objective: to collect samples for biomarker analysis; to investigate the effects of genetic variation in disease genes and drug target genes on asthma and/or subject response to brodalumab |
|
E.3 | Principal inclusion criteria |
- Men or women ≥ 18 to ≤ 75 years of age at the time of screening
- Diagnosis of asthma, and presently has reversibility over pre-bronchodilator FEV1 of ≥ 20% at screening and ≥ 15% at baseline, demonstrated in the office with SABA inhalation (up to 8 puffs) or nebulized equivalent (up to 2 treatments with 2.5 mg albuterol/salbutamol)
- Percent of predicted FEV1 ≥ 40% and ≤ 80% at screening and baseline visits
- ICS ≥ 200 and ≤ 1000/μg/day fluticasone powder or equivalent. Stable ICS dose for ≥ 30 days before screening. Must have used ICS for at least the last 3 consecutive months prior to screening
- Ongoing asthma symptoms with ACQ composite score at screening and baseline ≥ 1.5 points
- At least 1 asthma exacerbation in the year before screening
- Nonsmoker or ex-smoker with < 10/pack-years (eg, 1 pack per day for 10 years) who stopped ≥ 1 year before screening |
|
E.4 | Principal exclusion criteria |
- History of chronic obstructive pulmonary disease or other chronic pulmonary condition other than asthma
- Any, systemic disease considered by the investigator to be clinically significant and uncontrolled or unstable (eg, diabetes, liver disease, renal failure, congestive heart failure, coronary artery disease, myocardial infarction or unstable angina within 12 months prior to screening, angina pectoris within 12 months before screening).
