The key secondary outcomes are as follows: 1) other inflammatory cell markers in the airway (e.g., CD4, CD8, CD68, CD45, EG2/MBP, tryptase, and neutrophil elastase); 2) RANTES (regulated on activation, normal T expressed and secreted) expression in airway; 3) FEV1 peak expiratory flows; 4) methacholine PC20; and 5) asthma symptom score.
