The trial is performed to assess the efficacy and safety of SLIT One birch for treatment of birch pollen induced allergy

Condition Intervention Phase
Allergy Biological: Sublingual immunotherapy Biological: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Multicentre, Randomised, Double-blind, Placebo-controlled Parallel Group Clinical Trial to Investigate the Efficacy and Safety of Specific Sublingual Immunotherapy With SLITone Birch in Patients With Seasonal Birch Pollen Induced Rhinoconjunctivitis

Further study details as provided by ALK-Abelló A/S:

Primary Outcome Measures:
  • Daily Rhinoconjunctivitis Symptom Score [ Time Frame: Birch pollen season 2006 ]
    A total of 6 rhinoconjunctivitis symptoms are recorded (runny nose, blocked nose, sneezing, itchy nose, gritty feeling/red/itchy eyes, watery eyes). Each symptoms is scored on a scale from 0-3 (no symptoms-severe symptoms). I.e. the total daily score can be 0-18.

  • Daily Rhinoconjunctivitis Rescue Medication Score [ Time Frame: Birch pollen season 2006 ]
    Rescue medication (desloratadine tablets, budesonide nasal spray, prednisone tablets) used for treatment of rhinoconjunctivitis symptoms not controlled by the study medication, were recorded. The total daily score was 0-30 (No medication-Maximum use of medication).

Secondary Outcome Measures:
  • Global Improvement of Rhinoconjunctivitis Symptoms Assessed by the Subjects [ Time Frame: Birch pollen season 2006 ]
    The number of participants who reported improved overall symptoms compared to the previous birch pollen season (each patient was asked to compare his/her symptoms in the 2006 birch pollen season with the symptoms in the 2005 birch pollen season).

  • Adverse Events [ Time Frame: Birch pollen season 2006 ]
    An adverse event was defined as: Any untoward medical occurence in a patient or clinical trial subject administered a trial product and which does not necessarily have a causal relationship with this treatment (International Conference of Harmonisation (ICH) Harmonised Tripartite Guideline E2A, Step 5).
