Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the efficacy of four different doses of CLUSTOID® Birke compared between each other and to placebo. The primary efficacy endpoint is defined as percentage of patients with an increased dosing step needed to provoke a positive response in the titrated nasal provocation test (tNPT) post-treatment compared with pre-treatment (i. e. any improvement) in each of the five study groups.;Secondary Objective: To assess the tolerability and safety of four different doses of CLUSTOID® Birke compared between each other and to placebo by occurrence of treatment-emergent adverse drug reactions.;Primary end point(s): To assess the efficacy of four different doses of CLUSTOID® Birke compared between each other and to placebo. The primary efficacy endpoint is defined as percentage of patients with an increased dosing step needed to provoke a positive response in the titrated nasal provocation test (tNPT) post-treatment compared with pre-treatment (i. e. any improvement) in each of the five study groups.;Timepoint(s) of evaluation of this end point: 11 months after start of trial

Secondary

MeasureTime frame
Secondary end point(s): To assess the tolerability and safety of four different doses of CLUSTOID® Birke compared between each other and to placebo by occurrence of treatment-emergent adverse drug reactions.;Timepoint(s) of evaluation of this end point: 11 months after start of trial
