Primary Outcome Measures

Name	Time	Method
Concentration required to elicit a positive response after nasal provocation test (NPT)	4 months	Change in the threshold concentration of mite allergen extract, measured in Histamine Equivalent Prick per ml (HEP/ml), needed to trigger a positive response after nasal provocation test (NPT) assessed by acoustic rhinometry.; This will be compared between the beginning and end of the trial and among active groups and placebo.

Secondary Outcome Measures

Name	Time	Method
Dose finding skin prick test	4 months	Comparison between the beginning and end of the trial and among active groups and placebo
Number of participants with treatment-related adverse events as assessed by MM09-SIT-013	4 months	Comparison between the beginning and end of the trial and among active groups and placebo
