<p>Primary endpoints will be:<br /><br>• The mean daily combined Symptom-Medication-Score (SMS)<br /><br>during the grass pollen peak of treatment year 1. The mean<br /><br>daily combined SMS will be compared between the treatment group and placebo.<br /><br>• The mean daily combined Symptom-Medication-Score (SMS)<br /><br>during the grass pollen peak of treatment year 2. The mean<br /><br>daily combined SMS will be compared between the treatment groups and placebo.<br /><br>Co-primary Safety Endpoints<br /><br>• Frequency of AEs concerning occurrence, seriousness,<br /><br>intensity and relationship to study drug.<br /><br>• Frequency and grading of local and systemic reactions.<br /><br>• Vital functions and findings of physical examination<br /><br>• Safety Laboratory (Hematology, blood biochemistry, and urine<br /><br>analysis)</p><br>
