| Main Objective: The primary objectives of the trial are: To demonstrate non-inferiority of vestibular administration of SLITonePLUS (Group V) compared to the sublingual administration (Group S) with regard to changes from baseline in spec. IgE-blocking factor against Betula verrucosa after 36 (in hierarchical order: 24, 12, 8, 4) weeks of treatment (a = 0.025 one-tailed, non-inferiority margin d = -0.075). The study outcome will be classified as successful if a significant non-inferiority is demonstrated on step 1 (week 36) of the ordered test. IN CASE OF SUCCESSFUL STUDY OUTCOME, tests of superiority of Group V vs. Group S will be carried out at each control visit (a = 0.025 one-tailed).;Secondary Objective: Secondary objectives are: To compare both administration routes after 4, 8, 12, 24, and 36 weeks of treatment with regard to changes from baseline in spec. IgG4 against Betula verrucosa in a repeated measurement design with baseline as covariate (logarithmically transformed data). To compare both administration routes after 4, 8, 12, 24, and 36 weeks of treatment with regard to changes from baseline in spec. IgE against Betula verrucosa in a repeated measurement design with baseline as covariate (logarithmically transformed data). To compare both administration routes with regard to the incidences of the following local reactions: oral pruritus, oedema mouth, oropharyngeal swelling, pharyngeal oedema, swollen tongue, glossodynia. Clinical;Primary end point(s): Immunological changes from baseline in spec. IgE-blocking factor against Betula verrucosa after 36, (24, 12, 8, 4) weeks of treatment with SLITonePLUS. | — |
