Study Overview
Brief Summary
The primary objective of the study is to determine the ability of reslizumab administered by subcutaneous injection to produce a corticosteroid-sparing effect in patients with oral corticosteroid (OCS)-dependent asthma and elevated blood eosinophils, without loss of asthma control.

Outcomes
Primary Outcomes
Number of Participants With Reduction In Daily Oral Corticosteroid (OCS) Dose During Weeks 20-24 As Compared to the Optimized Dose At Baseline
Time Frame: Baseline (Day 1), Weeks 20-24
The primary endpoint was the 5-level categorized percent reduction in OCS dose during weeks 20 to 24 compared with the optimized dose at baseline. The primary analysis incorporated data from all randomized patients. Analysis of the primary and secondary variables related to categorical OCS dose reduction incorporated missing data as non-responders. No decrease indicates there was no decrease in OCS, loss of baseline asthma control during weeks 20 to 24, or discontinuation from study drug.
Secondary Outcomes
- Annualized Rate of Clinical Asthma Exacerbations (CAEs)(Day 1 through Week 24)
- Percentage of Participants Achieving an OCS Dose of 0 mg at Weeks 20-24 While Maintaining Asthma Control(Weeks 20-24)
- Participants With Treatment-Emergent Anti-Drug Antibody (ADA) Responses(Weeks 4, 8, 12, 24 or early withdrawal.)
- Participants With Adverse Events(Day 1 up to Week 24 (end of treatment visit); Data were included between Day 1 and Week 24 for completed patients, and Day 1 and 4 weeks after the last dose of study drug for patients who discontinued treatment early.)
- Percentage of Participants Achieving a >=50% Reduction in OCS Dose at Weeks 20-24 Compared to Baseline While Maintaining Asthma Control(Baseline (Day 1), Weeks 20-24)
- Percentage of Participants Achieving an OCS Dose of <=5 mg at Weeks 20-24 While Maintaining Asthma Control(Weeks 20-24)
- Percent Change From Baseline in Daily Oral Corticosteroid (OCS) Dose During Weeks 20-24 Using a Mixed Model for Repeated Measures(Baseline (Day 1), Weeks 20-24)
- Percentage of Participants Achieving a >=5 mg Reduction in OCS Dose at Weeks 20-24 Compared to Baseline While Maintaining Asthma Control(Baseline (Day 1), Weeks 20-24)
