Brief summary
The overall objective of this study is to determine an optimal dose and dosing regimen of PT001 MDI for further evaluation in later stage studies.
Detailed description
The primary objective of this study is to demonstrate efficacy relative to placebo of PT001 MDI in patients with moderate to severe chronic obstructive pulmonary disease (COPD) within the range of doses evaluated in this protocol. To this end, each dose of PT001 MDI will be compared to placebo with respect to the primary efficacy endpoint, FEV1 AUC0-12 relative to baseline.
Interventions
PT001 MDI administered as two puffs BID for 7 days
Taken as 2 inhalations of the 17 µg per actuation strength MDI QID
Matching placebo to PT001 MDI administered as two puffs BID for 7 days

Recruitment details
Conducted at 9 US sites from May-October 2011. Entire period of study participation per subject was a maximum of 15 weeks. Planned target enrollment of 84 subjects.
Pre-assignment details
This was a chronic dosing study (7 days), 3-period, 6-treatment, incomplete block, crossover study. Each subject received 3 of 6 possible treatments; each treatment period was separated by a washout period 7-28 days. By-treatment sequence tabulations of the data were not pre-specified.
