- Scientific TitleEfficacy and tolerability of Citrus/Cydonia comp. solution for injection in patients with grass pollenseasonal allergic rhinitis: Randomised, double-blind, placebo-controlled comparative clinical trial with three parallel treatment groups The CiSAR Study
- ACRONYM
- hypothesisHypothesis 1: There is a difference of at least 30% in mean “days with symptom control” between the Citrus/Cydonia comp. 1% verum group compared to the placebo group in the last two weeks of treatment in favour of Citrus/Cydonia comp. 1% solution for injection. Hypothesis 2: There is a difference of at least 15% in mean “days with symptom control” between the Citrus/Cydonia comp. 1-5% verum group compared to the Citrus/Cydonia comp. 1% verum group in the last two weeks of treatment in favour of Citrus/Cydonia comp. 1-5% solution for injection. Hypothesis 3: There is a statistically significant difference in the use of rescue medication during the whole treatment period between the verum and the placebo group in favour of Citrus/Cydonia comp. 1% solution for injection and Citrus/Cydonia comp. 1-5% solution for injection. Hypothesis 4: There is a statistically significant difference in the number of drop outs between the verum and the placebo group in favour of Citrus/Cydonia comp. 1% solution for injection and Citrus/Cydonia comp. 1-5% solution for injection.

- Primary outcomeDays with symptom control” defined by: a) A Total Symptom Score of ≤ 8 (while exposed to a mean pollen count of 20-50) or ≤ 12 (while exposed to a mean pollen count of > 50) and b) No use of rescue medication in the verum groups compared to the placebo group in the last two weeks of treatment
