Inclusion Criteria

  • Signed informed consent
  • Age ≥ 18 and ≤65 years
  • Moderate-to-severe birch pollen induced allergic rhinitis/rhinoconjunctivitis based on ARIA classification for at least 2 consecutive years
  • FEV1 (forced expiratory volume at one second) \> 70% (of predicted value) for patients with a history of asthma, FEV1 \> 70% or PEF (peak expiratory flow) \> 80% (of predicted value) for patients without a history of asthma
  • Positive SPT (skin prick test) for birch pollen (mean wheal diameter ≥ 3mm compared to negative control; negative control should be negative; histamine control should be positive (mean wheal diameter ≥ 3mm)) assessed during screening.
  • Serum specific anti-birch IgE (immunoglobulin E) concentration \>0.7 U/ml
  • Patients should be willing and capable to complete an e-diary daily during the birch pollen season (≥ 60% compliance in completion between Visit 1 and 2).
  • A positive Nasal Provocation Test to birch pollen at Visit 2 (Lebel score ≥ 6) or a documented positive test within 1 year before start of treatment

Exclusion Criteria

  • Patients sensitized and symptomatic to pets should not be included if they are regularly exposed to pets
  • Specific immunotherapy (SCIT or SLIT) with birch pollen or a cross-reacting allergen within the last 5 years
  • SPT positive (mean wheal diameter ≥ 3mm compared to negative control; negative control should be negative; histamine control should be positive (mean wheal diameter ≥ 3mm)) patients to allergen(s) other than birch pollen, in the absence of a negative provocation test for this allergen(s) (within 1 year), who are expected to have clinically relevant symptoms during the birch pollen season
  • Completed unsuccessful allergen-specific immunotherapy (SCIT or SLIT) within the last 5 years
  • (Ongoing) allergen-specific immunotherapy (SCIT or SLIT) with any allergen(s) during the study period
  • Vaccination one week before start of treatment and/or during the up-dosing phase
  • Treatment with experimental products within the last 3 months or biologicals (including anti-IgE or TNF (tumor necrosis factor) - α treatment) within the last 6 months or during the study
  • Uncontrolled asthma or other active respiratory diseases
  • Clinically significant chronic sinusitis, ocular infection or severe inflammation of the oral mucosa
  • Severe immune disorders (including auto-immune diseases) and/or diseases requiring immunosuppressive drugs
