E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of ALK HDM AIT given once daily compared to placebo in the treatment of HDM allergic rhinitis. The primary endpoint is the average total combined rhinitis score (TCRS) during the last 8 weeks of treatment. The TCRS is the sum of the allergic rhinitis daily symptom score (DSS) and the allergic rhinitis daily medication score (DMS) averaged over the last 8 weeks of treatment. |
|
E.2.2 | Secondary objectives of the trial |
To determine the effect of the ALK HDM AIT on average allergic rhinitis DSS, average allergic rhinitis DMS and average total combined rhinoconjunctivitis score.
Additional secondary objectives of the trial are:
To evaluate the safety and tolerability of ALK HDM AIT treatment
To determine the effect of the ALK HDM AIT on individual rhinitis and conjunctivitis symptoms, medication use, onset of action, treatment satisfaction, and generic and disease-specific quality of life. Immunological parameters will be investigated for a subset of the subjects. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
