E.5 End points |
E.5.1 | Primary end point(s) |
Emax(3-8): The maximal percentage decrease
from the pre-allergen challenge (post-diluentvalue) in FEV1 during 3 hours to 8 hours post- allergen challenge.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
21 Days (please see protocol) |
|
E.5.2 | Secondary end point(s) |
• Emax(o-3): max % decrease from the pre-allergen challenge (post-diluent value) in FEV1 during the first 3 hours post- allergen challenge (0 to 3 hours).
• Emax(3-8): The max % decrease from the pre-allergen challenge (post-diluent
value) in FEV1 between 3 hours and 8 hours post- allergen challenge (3 to 8 hours).
• AUEC(o-3): The area under the effect curve (AUEC) between 0 hours and 3 hours post-allergen challenge (using change from baseline FEV1
values, with post-diluent challenge value in FEV 1
as baseline). The parameter will be calculated using linear trapezoidal method.
• AUEC(3•Bl: The area under the effect curve (AUEC) between 3 hours and 8 hours post- allergen challenge (using change from baseline FEV1 values, with post-diluent challenge value in FEV1 as baseline), using linear trapezoidal method.
• Eavg(0-3) based upon AUEC(o-3)
• Eavg(3-SJ based upon AUEC<3.8l
• Emin,0.3l: The minimal percentage decrease from the pre-allergen challenge (post-diluent value) in FEV1 during the first 3 hours post-allergen challenge (0 to 3 hours).
• Emin<3.8l: The minimal percentage decrease from the pre-allergen challenge (post-diluent value) in FEV1 between 3 hours and 8 hours post-allergen challenge (0 to 3 hours).
• Absolute count and percentage differential in sputum eosinophils at approximately 8 hours after allergen challenge;
• Absolute count and percentage differential in sputum neutrophils at approximately 8 hours after allergen challenge;
• Change and percent change from baseline
(screening) in eosinophils and neutrophils at
8 hours post-allergen challenge.
