Has a post-bronchodilator FEV1 at screening of between 30% and 80% (inclusive) of the predicted normal value.
Subject demonstrates at screening at least a 120 mL increase in FEV1 within 1 hour of receiving 500 µg of ipratropium bromide from a PARI LC Sprint® nebulizer.

Subject has a history (or family history) of congenital prolonged QTc (corrected QT interval) syndrome or has an abnormal clinically significant electrocardiogram (ECG) at screening, including QTcB (QT interval corrected for heart rate using Bazett's formula) value >450 msec (males) or >470 msec (females); or shows evidence of clinically significant rhythm abnormality.
Subject has a known hypersensitivity to TD-4208 or similar drug class.
