E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Demonstrating safety and efficacy of a sublingual administration of grass pollen allergen in patients with allergic rhinitis (due to grass pollen allergy) with or without asthma.
Measurement includes symptom-medication-score between IMP and placebo group, respectively between baseline pollen season and first pollen season.

E.2.2 | Secondary objectives of the trial |
Efficacy in terms of immunologic blood parameters: allergen-specific IgE, IgG1 and IgG4, measured at start and end of IMP-season.
Long-term efficacy, measured by change in symptom-medication-score after two, respectively three years of treatment with IMP. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of this study is difference between active treatment and placebo in the change of the Area Under the Curve of the Symptom - Medication - Score (SMS) from the baseline season to the season after 1 year of treatment. The SMS will be calculated by the daily sum of symptoms and use of anti-allergic medication documented in patients’ diaries during the pollen season. |
