• •Inability to tolerate nebulization based on the Principal Investigator's medical judgment or a ≥12% drop in FEV1, at either 15 or 30 minutes after the completion of administration of a dose of nebulization test solution (SWFI) of the same volume and under the same nebulization conditions that is planned to be used for study drug administration, compared to the FEV1 obtained immediately prior to administration of the nebulization test solution.
