Inclusion and exclusion criteria
Key inclusion criteria for study:
Adults and adolescents greater than or equal to (>=)12 years of age, at the time of signing the informed consent/assent.
Participants must have a documented physician diagnosis of asthma for >=2 years that meets the National Heart, Lung, and Blood Institute guidelines (NHLBI) or Global Initiative for Asthma (GINA) guidelines and
Persistent airflow obstruction as indicated by (i) For participants >=18 years of age at Visit 1, a pre-bronchodilator FEV1 less than (<)80 percent (%) predicted National Health and Nutrition Examination Survey (NHANES III) recorded at Visit 1.
(ii) For participants 12-17 years of age at Visit 1: A pre-bronchodilator FEV1 <90% predicted (NHANES III) recorded at Visit 1 or FEV1: Forced Vital Capacity (FVC) ratio <0.8 recorded at Visit 1.
Key inclusion criteria for randomization:
An elevated peripheral blood eosinophil count of >=300 cells per microliter demonstrated in the past 12 months prior to Visit 1 that is related to asthma or an elevated peripheral blood eosinophil count of >=150 cells per microliter at Screening Visit 1 that is related to asthma.
Evidence of airway reversibility or responsiveness as documented by either:
(i) Airway reversibility (FEV1>=12% and 200 milliliter [mL]) demonstrated at Visit 1 or Visit 2 using the Maximum Post Bronchodilator Procedure or (ii) Airway reversibility (FEV1>=12% and 200 mL) documented in the 24 months prior to Visit 2 (randomization visit) or (iii) Airway hyper-responsiveness (methacholine: Provocative concentration causing a 20% fall in FEV1 [PC20] of <8 milligrams per milliliter (mg/mL), histamine: Provocative dose that decreases FEV1 by 20% [PD20] of <7.8 micromoles, mannitol: decrease in FEV1 as per the labelled product instructions) documented in the 24 months prior to Visit 2 (randomization visit).
