OBJECTIVES: To document the effectiveness and safety of sublingual allergen immunotherapy (SLIT) with a five-grass pollen tablet (Oralair ) and compare different treatment options in a broad, non-selected population of patients in a real-world clinical setting.
RESEARCH DESIGN AND METHODS: This was a 2 year, open, prospective, multicenter, single-arm, non-interventional study. Patients with a history of clinically relevant allergic symptoms caused by grass pollen, confirmed by skin prick testing, received treatment with the five-grass pollen tablet. Concomitant treatment with symptomatic medication and/or additional SLIT or subcutaneous immunotherapy (SCIT) was permitted. Twelve-month data are presented here. Effectiveness was assessed comparing a combined rhinoconjunctivitis (RC) score derived from the severity of rhinitis and conjunctivitis symptoms under treatment with retrospective data of the previous year.
RESULTS: A total of 1408 patients participated in the study, of whom 434 were children/adolescents and 962 polyallergic. Compared with the grass pollen season preceding five-grass pollen tablet treatment, a statistically significant reduction of 49.9% was achieved in RC score for the total population (p < 0.001), and an improvement in overall health was perceived by 90.9% of patients. The overall population of polyallergic patients derived similar benefits from treatment with the five-grass pollen tablet as monoallergic patients. The percentage reduction in RC score was larger in polyallergic patients taking no additional therapy (60.2%) than in those taking concomitant symptomatic medication (38.1%) or allergen immunotherapy (AIT) (50.8%). Within the last of these groups, RC score improved by 47.6% among patients receiving additional SCIT, versus 54.8% with additional SLIT. Adverse drug reactions, reported in 15.3% of study participants, were mostly local in nature and mild or moderate in intensity.
CONCLUSIONS: After 1 year of treatment, polyallergic patients responded similarly to the five-grass pollen tablet as monoallergic patients. For polyallergic patients in whom additional treatment was needed, a second SLIT may be more beneficial than a SCIT or symptomatic co-medication.
