6.Subject should be a dual responder to inhaled bronchial allergen challenges as manifested by positive allergen-induced early (LAR) and late airway bronchoconstriction (LAR) at screening, defined as follows:
•EAR is defined as a fall in FEV1 of at least 20% from pre-challenge post diluent baseline values during the 30 minutes after inhaled bronchial allergen challenge.
•LAR is defined by a fall from post diluent value of FEV1 of at least 15% on at least 3 occasions, 2 of which must be consecutive, between 3 to 8 hours after inhaled allergen challenge.
7.Able to correctly use the DPI inhaler and to generate sufficient peak inspiratory flow rate (PIFR) (at least 40 L/min) using the In-Check DIAL device at Screening and prior to dosing on Day 1 of Treatment Period 1.
8.Subject has no clinically significant abnormalities as determined by the PI in the results of laboratory evaluations at Screening, including:
•Liver function tests (i.e., ALT, AST, ALP, GGT, and bilirubin) = upper limit of normal or deemed medically acceptable at the discretion of the PI and Sponsor’s Medical Monitor
•Absolute lymphocyte counts within normal range or should be deemed medically acceptable at the discretion of the PI and Sponsor’s Medical Monitor
9.Subject must have a negative QuantiFeron® Test result at Screening.
