Study Summary

A study evaluating efficacy and safety of repeated doses of PT027 compared to PT007 in patients with asthma and acute airway obstruction induced by repeated mannitol challenges

Primary Outcome

The efficacy of repeated dosing of PT027 relative to PT007, on post-dose lung function, when used by participants with asthma on SABA as-needed treatment only who are experiencing acute airway obstruction induced by mannitol challenges was assessed. Mannitol baseline was defined as the FEV1 result where a positive response to mannitol was observed prior to dosing of study drug for challenge 1 in Visit 2 and in Visit 3 (time 0). A positive response was defined as a ≥ 15% decrease from the FEV1 d
