This was a multicenter, open label, randomized, controlled, safety trial in subjects aged 6-75 years with a diagnosis of moderate to severe, persistent asthma. A total of 1899 subjects were randomized (2:1) to either the active treatment group or the control group. Upon successful completion of the screening period (~2 weeks), each subject entered the 24 week study.

Condition Intervention Phase
Asthma Drug: Xolair (omalizumab) Phase 3

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: A Multicenter, Randomized, Controlled, Open-Label Study to Evaluate the Safety of Xolair in Moderate to Severe Persistent Asthma Subjects Already Treated With Other Therapies (ALTO)

  • Diagnosis of aspirin or nonsteroidal anti-inflammatory drug-induced asthma
  • Active lung disease other than asthma (e.g., chronic bronchitis, emphysema, cystic fibrosis, chronic obstructive pulmonary disease)
  • History of smoking within 2 years of the study screening visit or history of smoking ≥ 10 pack years
  • Significant systemic disease (e.g., infection, hematologic, renal, hepatic, coronary heart disease or other cardiovascular diseases, endocrinologic or gastrointestinal disease) within the previous 3 months
