Authors' objectives: To determine the clinical effectiveness, safety and cost-effectiveness of omalizumab, as an add-on therapy to standard care, within its licensed indication, compared with standard therapy alone for the treatment of severe persistent allergic asthma in adults and adolescents aged 12 years and children aged 6-11 years.

Authors' recommendations: Omalizumab reduces the incidence of CS exacerbations in adults and children, with benefits on other outcomes in adults. Limited, underpowered subgroup evidence exists that omalizumab reduces exacerbations and OCS requirements in adults on OCSs. Evidence in children is weaker and more uncertain. The ICERs are above conventional NHS thresholds of cost-effectiveness. The key drivers of cost-effectiveness are asthma-related mortality risk and, to a lesser extent, HRQoL improvement and OCS-related adverse effects. An adequately powered double-blind RCT in both adults and children on maintenance OCSs and an individual patient data meta-analysis of existing trials should be considered. A registry of all patients on omalizumab should be established.
