研究组 & 干预措施
Placebo
Placebo was given the same way as a sublingual preparation.
干预措施: Comparator (Other)
Liquid formulation of an extract of a 6 grass pollen mixture
Sublingual application containing allergen extracts of 6 grass pollen species (Holcus lanatus, Dactylus glomerata, Lolium perenne, Phleum pratense, Poa pratensis, Festuca pratensis) pollen allergen extract.
The study solution was applied sublingually, kept under the tongue for 3 minutes, and swallowed thereafter. Initial treatment was applied on the first day of treatment with a starting dose of 25% of the maintenance dose. Increasing doses of 50% were applied with the second and 100% with the third dose to give the maximum (=maintenance) dose. This was followed by a daily patient selfadministered treatment with the maintenance dose.
干预措施: Grass pollen formulation (Biological)
结局指标
主要结局
Symptom and Medication Score (SMS)
时间窗: 1.5 years of therapy
The primary endpoint is the change of the area under the curve (AUC, derived from an analysis period of 42 days) of the daily sum of the Symptom and Medication Score (SMS) from the baseline measurement to the measurement after 1.5 years of therapy.
次要结局
- Visual Rating Scale(1.5 years)
