Study Endpoints
Primary Endpoints
Area Under the Curve of Change From Baseline in Forced Expiratory Volume (in 1 Second) (FEV1) From 3 to 8 Hours After Inhaled Allergen Challenge at Day 14
Day 14 of treatment period: 3 to 8 hours after allergen challenge

Values are reported as a weighted mean derived by calculating the AUC change from baseline over the relative time interval, divided by the time interval.

To assess the safety and tolerability of SAD of TD-8236 by assessing the number, severity and type of treatment emergent adverse events
Day 1 through Day 8
To assess the safety and tolerability of MAD of TD-8236 by assessing the number, severity and type of treatment emergent adverse events
Day 1 through Day 14
Secondary Endpoints
