- The patient has an ACQ score of at least 1.5.
- At screening, the patient has airway reversibility of at least 12% to beta-agonist administration.
- The patient is currently taking fluticasone at a dosage of at least 440 µg daily (or equivalent). Patients' baseline asthma therapy regimens (including but not limited to inhaled corticosteroids, leukotriene antagonists, 5-lipoxygenase inhibitors, cromolyn) must be stable for 30 days before screening and continue without dosage changes throughout study.
- Female patients must be surgically sterile, 2 years postmenopausal, or must have a negative beta-human chorionic gonadotropin (ßHCG) result for a pregnancy test at screening (serum) and baseline (urine).
- Female patients of childbearing potential (not surgically sterile or 2 years postmenopausal), must use a medically accepted method of contraception and must agree to continue use of this method for the duration of the study and for 30 days after participation in the study. Acceptable methods of contraception include barrier method with spermicide, abstinence, intrauterine device (IUD), or steroidal contraceptive (oral, transdermal, implanted, and injected).
- Written informed consent is obtained.
- The patient is in reasonable health (except for diagnosis of asthma) as judged by the investigator, and as determined by a medical history, medical examination, electrocardiogram (ECG) evaluation, serum chemistry, hematology, urinalysis, and serology.
- The patient must be willing and able to comply with study restrictions and to remain at the clinic for the required duration during the study period, and be willing to return to the clinic for the follow-up evaluation as specified in this protocol.
Exclusion Criteria:
Patients are excluded from participating in this study if 1 or more of the following criteria are met:
- The patient has another confounding underlying lung disorder (eg, chronic obstructive pulmonary disease, pulmonary fibrosis, lung cancer). The patient has other pulmonary conditions with symptoms of asthma and blood eosinophilia (eg, Churg-Strauss syndrome, allergic bronchopulmonary aspergillosis).
- The patient has a clinically meaningful comorbidity that would interfere with the study schedule or procedures, or compromise the patient's safety.
- The patient has known hypereosinophilic syndrome (HES).

Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) at Week 16 in Full Analysis Set
Délai: Baseline (Day 1), Week 16
|
FEV1 is a standard measurement of air movement in the lungs of patients with asthma. It is the volume of air expired in the first second of a forced expiration. Improvement in FEV1 is a measure in the reduction of bronchospasm, the reduction of airway inflammation, or both. FEV1 was measured using forced expiratory air spirometry. Data represent the slope estimate of change from baseline in FEV1 (measured in liters) at Week 16 versus baseline eosinophil count (measured in 10^9/liter) by treatment group. |

Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Over 16 Weeks Using Mixed Model for Repeated Measures
Délai: Baseline (Day 1), Weeks 4, 8, 12, 16
|
FEV1 is a standard measurement of air movement in the lungs of patients with asthma. It is the volume of air expired in the first second of a forced expiration. Improvement in FEV1 is a measure in the reduction of bronchospasm, the reduction of airway inflammation, or both. FEV1 was measured using forced expiratory air spirometry. Positive change from baseline scores indicate improvement in asthma control. During study (Weeks 4, 8, 12 and 16) average value was calculated using a mixed effects model for repeated measures (MMRM) with treatment (reslizumab or placebo), blood eosinophil count at baseline, and the interaction of treatment and eosinophil count as a random effect. |
Baseline (Day 1), Weeks 4, 8, 12, 16
|
Change From Baseline in Asthma Control Questionnaire (ACQ) Over 16 Weeks Using Mixed Model for Repeated Measures
Délai: Baseline (Day 1), Weeks 4, 8, 12, 16
|
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. Negative change from baseline scores indicate improvement in asthma control. During study (Weeks 4, 8, 12 and 16) average value was calculated from mixed model repeated measures (MMRM) with treatment, visit, treatment by visit interaction, history of asthma exacerbation in the previous year, height, baseline value, and sex as fixed factors, and patient as a random effect. |
Baseline (Day 1), Weeks 4, 8, 12, 16

Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) at Week 16 in FEV1 Subpopulation
Délai: Baseline (Day 1), Week 16
|
FEV1 is a standard measurement of air movement in the lungs of patients with asthma. It is the volume of air expired in the first second of a forced expiration. Improvement in FEV1 is a measure in the reduction of bronchospasm, the reduction of airway inflammation, or both. FEV1 was measured using forced expiratory air spirometry. As with the primary outcome, data represent the slope estimate of change from baseline in FEV1 (measured in liters) at Week 16 versus baseline eosinophil count (measured in 10^9/liter) by treatment group. However the FEV1 subpopulation includes participants with more impaired lung function (% predicted FEV1 <85% at baseline). |

Délai: Baseline (Day -2 to 1), Weeks 4, 8, 12, and 16
|
SABA are used for quick relief of asthma symptoms.
The number of times SABA therapy was used was assessed using 3 day recall at scheduled visits.
Participants were asked to recall whether SABAs were used within 3 days of the scheduled visit and, if so, how many puffs were used.
Daily use was the average of those 3 days.
Negative change from baseline scores indicate improvement in asthma control.
|
Baseline (Day -2 to 1), Weeks 4, 8, 12, and 16
|
Change From Baseline in Blood Eosinophil Counts at Weeks 4, 8, 12, 16, Follow-up (Week 28) and Endpoint
Délai: Baseline (Day 1), Weeks 4, 8, 12, 16, Follow-up (Week 28)

Participants With Treatment-Emergent Adverse Events
Délai: Day 1 to Week 28
|
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.
