Outcomes
Primary Outcome Measures
Allergy symptom severity scores on a scale from 0-3
Determine the dose-efficacy response relationship of the ALK tree AIT. This information will, in combination with the evaluation of the frequency and severity of adverse events, form the basis of the conclusion on the primary endpoint.
Adverse events frequency
Determine the dose-safety response relationship of the ALK tree AIT. This information will, in combination with the evaluation of the allergy symptoms, form the basis of the conclusion on the primary endpoint.
Secondary Outcome Measures
Adverse events severity
Determine the dose-safety response relationship of the ALK tree AIT. This information will, in combination with the evaluation of the allergy symptoms, form the basis of the conclusion on the primary endpoint.
