• Subjects 0 to <24 months of age must have a history of 3 episodes of respiratory symptoms that in the judgement of the investigator could be consistent with asthma or reactive airways disease.
• Subject must be in good health and not affected by any other chronic conditions, including respiratory disorders other than asthma.
• In subjects with a chest radiograph (taken 12 months prior to screening visit), no evidence of any chronic cardiopulmonary condition other than asthma should be present as discerned by the Investigator.

• Subject or parent/legal guardian who has daily commitments during the study that would interfere with trial measurements, compliance, or both.
• Subject who has a history of hospitalization for asthma, reactive airways disease, or bronchospasm within 4 weeks prior to screening or who is scheduled for in-patient hospitalization, including elective surgery during the course of the trial.
• Subject who has experienced significant blood loss within 60 days of study drug.
• Subject with a clinical diagnosis of cystic fibrosis.

Ventilatory support for elective non-cardiopulmonary surgery is not exclusionary. - Subject with any clinically significant abnormal laboratory values (hematology, blood chemistry).
• Subject with a clinically significant abnormal 12-lead ECG that would put the subject at risk for experiencing adverse cardiac effects.
• Subject who is a relative of a staff member.
