ObjectiveRandomized controlled trials (RCTs) have established the safety and efficacy of omalizumab on clinical parameters, and have also evaluated its impact on patient-reported outcomes (PROs). The purpose of this systematic literature review was to review published data based on PRO endpoints in order to determine the benefit of omalizumab as add-on therapy to inhaled corticosteroids in patients with moderate-to-severe persistent allergic asthma.MethodsA systematic literature review was conducted of reference databases and recent conferences. RCTs of add-on omalizumab therapy in adults, adolescents, and children with moderate-to-severe persistent asthma were included. Two researchers independently screened and reviewed articles with regards to inclusion and exclusion criteria for relevant studies.ResultsTwenty-six trials met the criteria for inclusion. Of these, PRO measures were included in 19 trials to capture the impact of omalizumab on symptoms, 11 assessed patients for health-related quality-of-life (HRQoL), and four evaluated asthma control. Other PROs related to global evaluation of treatment effectiveness and work productivity. Overall, results demonstrated a significant difference across most PROs in favor of omalizumab add-on therapy vs placebo or comparators.ConclusionsPROs are an integral part of outcome assessment in clinical trials related to asthma. The RCTs reviewed demonstrate that omalizumab treatment improves PROs in patients with moderate-to-severe persistent allergic asthma, particularly symptom control and HRQoL.
