Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A total of 869 patients were screened for enrollment into this study. Of the 869 patients screened, 511 patients at 103 centers in the US met entry criteria and were considered to be eligible for enrollment into the study.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Randomization was stratified by occurrence of asthma exacerbation(s) during the previous year (yes or no). Within each stratum, patients were randomly assigned in a 4:1 ratio to receive treatment with reslizumab at 3.0 mg/kg or matching placebo.

Reporting Groups
  Description
Placebo Placebo intravenous injection every 4 weeks for a total of 4 doses.
Reslizumab 3.0 mg/kg Reslizumab intravenous injection at a dosage of 3.0 mg/kg every 4 weeks for a total of 4 doses.

[1] n=98, 396, 494 The ACQ score was measured using the ACQ-7. Six questions are-self assessments; the seventh item is the result of the patient's % predicted FEV1 measurement. Each item has 7 possible answers on a scale of 0 to 6, and the total score is the mean of all responses (the total scale is therefore 0-6). A score of 0 indicates good asthma control; higher scores indicate increasingly poorer asthma control.
