Open-Label Extension Study to Evaluate the Long-Term Safety and Efficacy of Reslizumab (3.0 mg/kg) as Treatment for Patients (12 Through 75 Years of Age) With Eosinophilic Asthma

Participants With Treatment-Emergent 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.

Time frame: Day 1 (post-dose) to Week 65. The endpoint for adverse events was the last postbaseline observation, which included the 90 day follow-up visit.

Participants With Treatment-Emergent Potentially Clinically Significant (PCS) Abnormal Lab Values

Data represents participants with potentially clinically significant (PCS) abnormal serum chemistry, hematology, and urinalysis values on any of the during treatment lab analyses. Significance criteria: * Blood urea nitrogen: \>=10.71 mmol/L * Creatinine: \>=177 μmol/L * Uric acid: M\>=625, F\>=506 μmol/L * Aspartate aminotransferase: \>=3\*upper limit of normal (ULN). Normal range is 10-43 U/L * Alanine aminotransferase: \>=3\*ULN. Normal range is 10-40 U/L * GGT = gamma-glutamyl transpeptidase: \>= 3\*upper limit of normal. Normal range is 5-49 U/L. * Total bilirubin: \>=34.2 μmol/L * White blood cells- low: \<=3.0\*10\^9/L * White blood cells-high: \>=20\*10\^9/L * Hemoglobin: M\<=115, F\<=95 g/dL * Hematocrit: M\<0.37, F\<0.32 L/L * Platelets: \>=700\*10\^9/L * Absolute neutrophil count: \<=1.0\*10\^9/L * Eosinophils: \>=10 * Urinalysis: ketones, blood, glucose, and total protein: \>=2 unit increase from baseline

Time frame: Weeks 4, 8, 24 and 48

Participants With Treatment-Emergent Potentially Clinically Significant (PCS) Vital Signs Values

Data represents participants with PCS vital sign values during any of the during treatment visits or the follow-up visit. Significance criteria * Sitting heart rate-high: \>100 and increase of \>= 30 beats/min (all ages) * Sitting heart rate-low: \<50 and decrease of \>=30 beats/min * Sitting systolic blood pressure (BP)-high: \>130 and increase of \>=30 mmHg (ages 12-17) * Systolic BP-low: \<90 and decrease of \>=30 mmHg (ages \>=18) * Systolic BP-high: \>160 and increase of \>=30 mmHg (ages \>=18) * Sitting diastolic BP-low: \<55 and decrease of \>=12 mmHg (ages 12-17) * Diastolic BP-high: \>85 and increase of \>=12 mmHg (ages 12-17) * Diastolic BP-low: \<50 and decrease of \>=12 mmHg (ages \>=18) * Diastolic BP-high: \>100 and increase of \>=12 mmHg (ages \>=18) * Respiration rate: \>20 and increase of \>=10 breaths/minute (ages 12-17) * Respiration rate: \>24 and increase of \>=10 breaths/minute (ages \>=18) * Body temperature-low: \<96.5° Fahrenheit (all ages) * Body temp-high: \>100.5° F (all ages)

Time frame: Week 4 to Week 65
