This study will assess efficacy and safety of intraseasonal specific short-term immunotherapy with Depiquick® Birch in patients with allergic rhinitis and or rhinoconjunctivitis with or without intermittent asthma that have a clinical relevant IgE-mediated allergic sensitization against birch pollen. The term "intraseasonal" means that patients will start with immunotherapy treatment during the birch pollen season, i.e. when the already experience allergic symptoms.

研究组 & 干预措施
Depiquick® Birch
At the screening visit (Visit 1), patients will be instructed how to complete the eDiary. Eligible patients will return for visit 2 as soon as they experience significant allergic symptoms. Significant allergic symptoms are defined by a symptom score ≥ 2. If the patients' eligibility has been confirmed according to inclusion/exclusion criteria checklist, randomization to one of the 2 treatment arms will be conducted. Patients will receive two consecutive subcutaneous injections of study medication (0,2 and 0,3 ml) with a time lag of ≥ 30 minutes. Patients return to the study site in weekly intervals for visit 3, visit 4, visit 5, visit 6, and visit 7 to receive study medication injections (0,5 ml each). If treatment is completed before the end of the tree pollen season, patients will be followed-up by telephone calls every 4 weeks until the end of the tree pollen season. The study completion visit will take place 4 weeks after the end of the tree pollen season.

结局指标
主要结局
Combined Symptom and Medication Score (SMS)
时间窗: From the start of treatment until the end of the relevant pollen exposition time.
The SMS represents the sum of the mean daily symptom severity score plus the mean daily rescue medication score. The symptom severity score is defined as the mean of the daily symptom severity scores during the pollen season. The rescue medication score is defined as the mean of the daily rescue medication scores during the pollen season. A lower score indicates an improvement in the allergic condition. Minimum score of the SMS is "0", maximum score is dependent on intake of rescue medication.
次要结局
- Combined Symptom and Medication Score (SMS)(date of randomization until 4 weeks after the end of the birch pollen season 2012, assessed up to 5 months)
- Onset of action (patient's assessment)(date of randomization until 4 weeks after the end of the birch pollen season 2012, assessed up to 5 months)
- Rhinoconjunctivitis Quality of Life questionnaire (RQLQ)(Visits 2, 4, 6, and 7)
