Exclusion criteria

Exclusion criteria: E1. A clinically relevant history of symptomatic seasonal allergic rhinoconjunctivitis and/or asthma caused by an allergen to which the subject regularly exposed and overlapping with the 8-week efficacy assessment period. E2. A clinically relevant history of symptomatic allergic rhinoconjunctivitis caused by mould or by animal hair and dander to which the subject is regularly exposed. E3. Reduced lung function (defined as FEV1<70% of predicted value after adequate pharmacologic treatment). E4. A clinical history of uncontrolled asthma7 within 3 months prior to screening. E5.

Design outcomes

Primary

MeasureTime frame
Main Objective: 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.;Secondary Objective: 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.;Primary end point(s): The average total combined rhinitis score (TCRS) during the last 8 weeks of the 12 months period of treatment. The TCRS is the sum of the total allergic rhinitis daily symptom score (DSS) and the allergic rhinitis daily medication score (DMS) averaged over the last 8 weeks of the 12 months period of treatment.;Timepoint(s) of evaluation of this end point: Measured over the last 8 weeks of the 12 months period of treatment

Secondary

MeasureTime frame
Secondary end point(s): The average total allergic rhinitis DSS during the last 8 weeks of 12 months treatment. The average total allergic rhinitis DMS during the last 8 weeks of 12 months treatment. The average total combined allergic rhinoconjunctivitis score during the last 8 weeks of 12 months treatment Other efficacy endpoints include: The average total allergic rhinoconjunctivitis DSS during the last 8 weeks of 12 months treatment. The average total allergic rhinoconjunctivitis DMS during the last 8 weeks of 12 months treatment. The average total allergic conjunctivitis DSS, allergic conjunctivitis DMS and combined conjunctivitis score during the last 8 weeks of 12 months treatment. Onset of efficacy, based on DSS and DMS during all one week diary periods. The average individual allergic DSS during the last 8 weeks of 12 months treatment RQLQ. Global evaluation for efficacy. Immunology markers. Symptom free days. EQ-5D. TSQM II. WPAI-AS. Health care utilisation based on GP/specialist visits The safety endpoints for the trial include Local AEs including oral pruritus, ear pruritus, throat irritation and mouth oedema. AEs, SAEs, AE withdrawals, clinical laboratory tests, vital signs, physical examination;Timepoint(s) of evaluation of this end point: Measured over the last 8 weeks of the 12 months period of treatment
