- •History of any known immunodeficiency disorder
- •A positive hepatitis B surface antigen, or hepatitis C virus antibody, as determined by medical history and/or subject's verbal report
- •A positive human immunodeficiency virus test or is taking antiretroviral medications, as determined by medical history and/or subject's verbal report

结局指标
主要结局
Change at Day 92 From Baseline in Mean Asthma Control Questionnaire (ACQ) Scores (Intent-toTreat Analysis)
时间窗: Day 92
Change at Day 92 from baseline (Day 1, prior to dosing) in mean ACQ scores in pariticpants receiving 30, 100, or 300 mg MEDI-528 versus placebo (Intent-to-Treat Analysis). The 6-item ACQ is a participant-reported questionnaire assessing asthma symptoms (night-time waking, symptoms on waking, activity limitation, shortness of breath, wheezing) and daily rescue bronchodilator use. Participants were asked to recall how their asthma had been during the previous week. Questions were weighted equally and scored from 0 (totally controlled) to 6 (severely uncontrolled). The mean ACQ score is the mean of the responses. Mean scores of ≤ 0.75 indicate well-controlled asthma, scores between 0.76 and \< 1.5 indicate partly controlled asthma, and a score ≥ 1.5 indicates uncontrolled asthma. Individual changes of at least 0.5 are considered to be clinically meaningful.
