Arm Intervention/treatment
Experimental: Reslizumab 110 mg
Reslizumab was administered by subcutaneous injection (sc) in a dosage of 110 mg (1.0 mL) every 4 weeks for a total of six doses.
Drug: Reslizumab
Reslizumab 110 mg was administered by qualified study personnel as subcutaneous injections in the upper arm(s) once every 4 weeks for a total of 6 doses. Drug was supplied in pre-filled syringes.

Participants continue using their non-OCS background asthma medications without change during the study's treatment period.

Drug: Oral Corticosteroid (OCS)
After screening and prior to study start, the participant's OCS dose was adjusted to determine the minimal effective OCS requirement.

Matching placebo was administered by subcutaneous injection (sc) 1.0 mL every 4 weeks for a total of six doses.
Drug: Placebo
Placebo was administered by qualified study personnel as subcutaneous injections in the upper arm(s) once every 4 weeks for a total of 6 doses. Drug was supplied in pre-filled syringes.

Drug: Non-Oral Corticosteroid (non-OCS) Asthma Medication
Participants continue using their non-OCS background asthma medications without change during the study's treatment period.

Drug: Oral Corticosteroid (OCS)
After screening and prior to study start, the participant's OCS dose was adjusted to determine the minimal effective OCS requirement.




Primary Outcome Measures :
  1. 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 Outcome Measures :
  1. Percentage of Participants Achieving a >=50% Reduction in OCS Dose at Weeks 20-24 Compared to Baseline While Maintaining Asthma Control [ Time Frame: Baseline (Day 1), Weeks 20-24 ]

    Percentage of patients whose OCS dose at weeks 20-24 was reduced >=50% compared to baseline while maintaining asthma control.

    Patients listed as "no" did not achieve the 50% reduction in baseline OCS dose goal, or did achieve that goal but lost asthma control during weeks 20 to 24, or discontinued from study drug.


  2. Percentage of Participants Achieving an OCS Dose of <=5 mg at Weeks 20-24 While Maintaining Asthma Control [ Time Frame: Weeks 20-24 ]

    Percentage of participants whose OCS dose at weeks 20-24 was <=5 mg and they maintained asthma control.

    Patients listed as "no" had a week 20-24 OCS dose > 5 mg, or whose OCS dose was <=5 mg at weeks 20-24 but did not maintain asthma control, or they discontinued from study drug.


  3. Percent Change From Baseline in Daily Oral Corticosteroid (OCS) Dose During Weeks 20-24 Using a Mixed Model for Repeated Measures [ Time Frame: Baseline (Day 1), Weeks 20-24 ]

    The baseline OCS dose is the prescribed optimized OCS dose following the OCS optimization period. Endpoint data are presented using an on-treatment approach. In this context, 'endpoint' was defined as the last observation obtained at a scheduled or qualified early termination visit during the treatment period. Weeks 20-24 data is included between the Week 20 dose and Week 24 for completed patients; last dose of study drug to 4 weeks after the last dose of study drug for patients who discontinued treatment early. Measurements collected outside of these defined timeframes are excluded from the analyses.

    The mixed model repeated measures (MMRM) included fixed effects for treatment, visit, treatment by visit interaction, age group, and OCS dose group, duration of OCS use and baseline value as covariates, and patient as a random effect. Unstructured covariance was assumed for the repeated measures.


  4. Percentage of Participants Achieving a >=5 mg Reduction in OCS Dose at Weeks 20-24 Compared to Baseline While Maintaining Asthma Control [ Time Frame: Baseline (Day 1), Weeks 20-24 ]
    Percentage of participants whose OCS dose at weeks 20-24 was reduced by at least 5mg from baseline and maintained asthma control. Patients listed as "no" had a week 20-24 OCS dose that did not meet the threshold of a 5mg reduction, or whose OCS dose met the threshold but did not maintain asthma control, or discontinued from study drug.

  5. Annualized Rate of Clinical Asthma Exacerbations (CAEs) [ Time Frame: Day 1 through Week 24 ]
    The annual exacerbation rate is based on clinical asthma exacerbations reported by the investigator in the eCRF.

  6. Percentage of Participants Achieving an OCS Dose of 0 mg at Weeks 20-24 While Maintaining Asthma Control [ Time Frame: Weeks 20-24 ]

    Percentage of participants who discontinue use of OCS during weeks 20-24 while maintaining asthma control.

    Patients listed as "no" continued to use OCS during weeks 20-24, or who discontinued use of OCS during weeks 20-24 but lost control of their asthma, or discontinued from study drug.


  7. Participants With Treatment-Emergent Anti-Drug Antibody (ADA) Responses [ Time Frame: Weeks 4, 8, 12, 24 or early withdrawal. ]

    Treatment-emergent responses were defined as a positive sample post-baseline (negative baseline) OR a titer increase of >=4-fold relative to a positive baseline sample.

    Two types of antibody assay were performed, an immunogenicity status assay (ADA) and neutralizing assay (NAb).

    The ADA assay produces a positive or negative result. For samples with a positive result, a neutralizing assay was performed, which also produces a positive or negative result.


  8. Participants With Adverse Events [ Time Frame: 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. ]

    An adverse event is any untoward medical occurrence in a patient administered a pharmaceutical product, regardless of whether it has a causal relationship with this treatment. In this study, asthma exacerbations (which are efficacy parameters) should not be recorded as adverse events unless assessed by the investigator as more severe than the patient's usual disease course. Relation of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.

    Treatment-related adverse events or adverse events related to OCS use included events with missing relationship to study drug or OCS use, respectively.
