Randomized Controlled Trial Multicenter Study Clinical Trial
The anti-IgE antibody omalizumab improves asthma-related quality of life in patients with allergic asthma.
The aim of the present study was to determine the effect of treatment with omalizumab, an anti-immunoglobulin E antibody, on asthma-related quality of life (AQoL) in patients with moderate-to-severe allergic asthma. A total of 546 patients with allergic asthma were randomised to double-blind subcutaneous treatment with either placebo or omalizumab for 52 weeks. A constant beclomethasone dipropionate dose was maintained during the first 16 weeks (steroid-stable phase). ⋯ Overall, almost 70% of patients and investigators rated treatment with omalizumab as "excellent/good", compared with approximately 40% of placebo recipients. Clinical studies show that omalizumab enhances disease control whilst reducing corticosteroid consumption in patients with allergic asthma. The results of the present study show that these changes are paralleled by improvements in asthma-related quality of life that are meaningful to such patients.
