Brief Summary:
The purpose of this study is to assess the efficacy of one dose of sublingual immunotherapy (SLIT) administered to children and adolescents as allergen-based tablets once daily over a period of 24 months over 3 years compared to placebo, for reduction of allergic rhinitis symptoms and rescue medication use.

Condition or disease Intervention/treatment Phase
Allergic Rhinitis Due to Dust Mite Drug: Dpte and Dfar Allergen Extracts Drug: placebo Phase 3

Detailed Description:

After the screening period, the patients will be administered 300 IR house dust mite allergen based tablets or placebo, once a day, for a period of 36 months with two windows of 8 months and 6 months without treatment. The carry over effect will be evaluated after a treatment free follow up period of 24 months.

An independent Data Monitoring Committee will be constituted to evaluate the efficacy and safety data at the end of Year 1 and Year 3, and the post-treatment long-term efficacy data at the end of year 4.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female outpatients, aged 5-17 years inclusive
  • History of house dust mite-related allergic rhinitis for at least 1 year requiring regular intake of symptomatic treatment(s)
  • Sensitised to D. pteronyssinus and/or D. farinae (positive skin prick test with wheal diameter greater than 3 mm and specific IgE level ≥ 0.7 kU/L)

Exclusion Criteria:

  • patients sensitised to aspergillus, cladosporium, alternaria
  • patients sensitised to parietaria , ragweed, or mugwort, if this allergen is endemic to the region
