MeasureTime frameDescription
Change From Baseline In Forced Expiratory Volume In 1 Second (FEV1) Over 16 Weeks Using Mixed Model for Repeated MeasuresDay 0 (baseline, pre-dose), Weeks 4, 8, 12 and 16FEV1 is a standard measurement of air movement in the lungs of patients with asthma obtained from pulmonary function tests. It is the volume of air expired in the first second of a forced expiration using a spirometer. The during treatment (weeks 4, 8, 12 and 16) average FEV1 was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements. Positive change from baseline scores indicate improvement in asthma control.

MeasureTime frameDescription
Change From Baseline in Forced Expiratory Flow at 25% to 75% Forced Vital Capacity (FEF 25%-75%) Over 16 Weeks Using Mixed Model for Repeated MeasuresDay 1 (baseline, pre-dose), Weeks 4, 8, 12, 16The FEF 25%-75% is the force expiratory flow at 25% to 75% of the Forced Vital Capacity (FVC). The during treatment (weeks 4, 8, 12 and 16) average FEF 25%-75% was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements.
Change From Baseline in % Predicted Expiratory Volume In 1 Second (FEV1) at Week 16 and at EndpointDay 1 (baseline, pre-dose), Week 16, endpointThe percent predicted FEV1 is the ratio of the volume of air expired in the first second of a forced expiration to the patient's predicted FEV based on a similar population without asthma. Endpoint =week 16 or early withdrawal.
Change From Baseline in Asthma Control Questionnaire (ACQ) Over 16 Weeks Using Mixed Model for Repeated MeasuresDay 1 (baseline, pre-dose), Weeks 4, 8, 12, 16The ACQ is a 7-item instrument that measures asthma control (Juniper et al 1999). Six questions are self-assessments; the seventh item, completed by a member of the study staff, is the result of the patient's 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 higher score is an indication of poorer asthma control. The during treatment (weeks 4, 8, 12 and 16) average ACQ was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements. Negative change from baseline scores indicate improvement in asthma control.
Change From Baseline in Asthma Quality of Life Questionnaire (AQLQ) at Week 16 or at Last Observed ValueDay 1 (baseline, pre-dose), Week 16 or last observed valueThe AQLQ is a 32-item instrument administered as a self-assessment (Juniper et al 1992). The questionnaire is divided into 4 domains: activity limitation, symptoms, emotional function, and environmental stimuli. Patients were asked to recall their experiences during the last 2 weeks and to respond to each question on a 7-point scale (1=severe impairment, 7=no impairment). The overall AQLQ score is the mean of all 32 responses. Five of the activity questions were patient-specific, which means that each patient identified and scored 5 activities in which the patient was limited by asthma; these 5 activities were identified at the first visit and retained for all subsequent follow-up visits. Positive change from baseline scores indicate improvement in quality of life. The AQLQ score was only assessed once during the study at week 16 or at early withdrawal, i.e. last postbaseline assessment if within 3 to 5 weeks of the last dose of study drug.
Change From Baseline in Asthma Symptom Utility Index (ASUI) Over 16 Weeks Using Mixed Model for Repeated MeasuresDay 1 (baseline, pre-dose), Weeks 4, 8, 12, 16The ASUI is an 11-item instrument designed to assess the frequency and severity of asthma symptoms and side effects, weighted by patient preferences (Revicki et al 1998). ASUI is a utility score that ranges from 0 to 1, with higher values indicating better asthma control. The during treatment (weeks 4, 8, 12 and 16) average ASUI was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements. Positive change from baseline values indicate improvement in asthma symptoms. Information was obtained from questionnaire about asthma symptoms.
Change From Baseline in Short-Acting Beta-Agonist (SABA) Use Over 16 Weeks Using Mixed Model for Repeated MeasuresDay 1 (baseline, pre-dose), Weeks 4, 8, 12, 16SABA are used for quick relief of asthma symptoms. To measure SABA use, at each clinical visit patients were asked to recall their usage of SABA therapy within the last 3 days of the scheduled visit. If usage was confirmed, the number of puffs used was recorded. For the purpose of summaries, an average daily usage was evaluated by dividing the total number of puffs recorded over 3 days by 3. The during treatment (weeks 4, 8, 12 and 16) average SABA use was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements. Negative change from baseline scores indicate improvement in asthma control.
Change From Baseline in Forced Vital Capacity (FVC) Over 16 Weeks Using Mixed Model for Repeated MeasuresDay 1 (baseline, pre-dose), Weeks 4, 8, 12, 16The FVC is the volume of air that can be forcibly blown out after full inspiration, measured in liters. The during treatment (weeks 4, 8, 12 and 16) average FVC was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements.
Participants With Adverse EventsDay 1 (post-dose) to Week 29An adverse event was defined in the protocol as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an inability to carry out usual activities. 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. The last postbaseline value for approximately 10 patients in each treatment group is the 90-day follow-up visit post end-of-treatment (approx. Week 29).
Participants With Treatment-Emergent Potentially Clinically Significant (PCS) Abnormal Lab ValuesDay 2 to Week 29Data represents participants with potentially clinically significant (PCS) abnormal serum chemistry, hematology (except for eosinophil values), and urinalysis values. Significance criteria: * Blood urea nitrogen: \>=10.71 mmol/L * Creatinine: \>=177 μmol/L * Uric acid: M\>=625, F\>=506 μmol/L * GGT = gamma-glutamyl transpeptidase: \>= 3\*upper limit of normal.

Participants With a Positive Anti-Reslizumab Antibody Status at Baseline, Week 8, Week 16, Endpoint, and OverallDay 1 (pre-dose), week 8, 16 and endpointCounts of participants with a positive anti-drug antibody (ADA) response during treatment is offered for the two experimental treatment arms. Blood samples were collected for determination of ADAs before study drug infusion at baseline, visit 4 (week 8), and at visit 6 (week 16: EOT or early withdrawal) from patients in all 3 treatment groups (ie, placebo, 0.3 mg/kg reslizumab, and 3.0 mg/kg reslizumab); however, only the blood samples drawn from patients treated with either 0.3 mg/kg reslizumab or 3.0 mg/kg reslizumab were analyzed. Serum samples from patients who were treated with reslizumab were analyzed for ADA by Teva (Teva Biopharmaceuticals USA, Rockville, MD) using a validated homogeneous solution-based bridging enzyme-linked immunosorbent assay (ELISA). Endpoint =week 16 or early withdrawal.
Change From Baseline in Blood Eosinophil Count Over 16 Weeks Using Mixed Model for Repeated MeasuresDay 1 (baseline, pre-dose), Weeks 4, 8, 12, 16Blood eosinophil counts were measured using a standard complete blood count (CBC) with differential blood test at each scheduled visit, and from all patients experiencing a serious adverse event, an adverse event leading to withdrawal, or an exacerbation of asthma symptoms. The during treatment (weeks 4, 8, 12 and 16) average eosinophil counts were estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements. Negative change from baseline values correlate to reduced asthma severity.

Change From Baseline in Asthma Quality of Life Questionnaire (AQLQ) at Week 16 or at Last Observed Value

The AQLQ is a 32-item instrument administered as a self-assessment (Juniper et al 1992). The questionnaire is divided into 4 domains: activity limitation, symptoms, emotional function, and environmental stimuli. Patients were asked to recall their experiences during the last 2 weeks and to respond to each question on a 7-point scale (1=severe impairment, 7=no impairment). The overall AQLQ score is the mean of all 32 responses. Five of the activity questions were patient-specific, which means that each patient identified and scored 5 activities in which the patient was limited by asthma; these 5 activities were identified at the first visit and retained for all subsequent follow-up visits. Positive change from baseline scores indicate improvement in quality of life. The AQLQ score was only assessed once during the study at week 16 or at early withdrawal, i.e. last postbaseline assessment if within 3 to 5 weeks of the last dose of study drug.

Change From Baseline in Short-Acting Beta-Agonist (SABA) Use Over 16 Weeks Using Mixed Model for Repeated Measures

SABA are used for quick relief of asthma symptoms. To measure SABA use, at each clinical visit patients were asked to recall their usage of SABA therapy within the last 3 days of the scheduled visit. If usage was confirmed, the number of puffs used was recorded. For the purpose of summaries, an average daily usage was evaluated by dividing the total number of puffs recorded over 3 days by 3. The during treatment (weeks 4, 8, 12 and 16) average SABA use was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements. Negative change from baseline scores indicate improvement in asthma control.

Participants With Adverse Events

An adverse event was defined in the protocol as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an inability to carry out usual activities. 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. The last postbaseline value for approximately 10 patients in each treatment group is the 90-day follow-up visit post end-of-treatment (approx. Week 29).
