The primary safety objective of this study was to compare the change in mean heart rate averaged over 24 hours post-dose, following twice daily dosing over 14 days with PT003 MDI, PT005 MDI, PT001 MDI or Foradil Aerolizer compared to baseline in patients with moderate to severe chronic obstructive pulmonary disease (COPD).

Safety Holter Monitoring Population: a sub-set of the safety population that had at least 18 hours of Holter monitoring data at Screening and at Day 1 and/or Day 14. Exclusions from this population were identified prior to database lock and unblinding.

Trough FEV1 averaged over Day 7 and Day 14

MITT - patients from the ITT population who completed at least one evaluable FEV1 spirometry assessment for baseline (pre-dose on Day 1) and had an evaluable FEV1 spirometry assessment on at least one of the following: Day 7 pre-dose or Day 14 pre-dose (or both).

The secondary objectives of the study was to further characterize cardiovascular safety parameters of all treatment groups including the maximum 24-hour heart rate, mean night-time and day-time heart rate, ventricular ectopic events, ventricular couplets, ventricular runs, the number of supraventricular runs, and sustained ventricular tachycardia (VT), supraventricular ectopic events, and other clinically relevant arrhythmias (such as atrial fibrillation).
