Study to Evaluate the Efficacy, Safety and Pharmacokinetics of PT001, PT003, and PT005 Following Chronic Dosing (7 Days) in Patients With Moderate to Very Severe Chronic Obstructive Pulmonary Disease (COPD)

This study has been completed.
Information provided by (Responsible Party):
Pearl Therapeutics, Inc. Identifier:
First received: March 9, 2010
Last updated: September 11, 2012
Last verified: September 2012
The purpose of this study is to evaluate, after 1 week of dosing, the efficacy and safety of PT003 compared with its individual components (PT001 and PT005), placebo and two active comparators to demonstrate superiority of the combination to its components, and to assess the relative contribution of the components compared with placebo, in patients with moderate to very severe COPD.

Primary Outcome Measures:
  • Change in forced expiratory volume in one second (FEV1) area under the curve from 0 to 12 hours [AUC(0-12)] from test day baseline [ Time Frame: Day 7 ]
    Day 7 time points for FEV1 are measured over 12 hours

Secondary Outcome Measures:
  • Peak FEV1, time to onset of action (greater than or equal to 10% improvement in mean FEV1), proportion of patients with greater than or equal to 12% improvement in FEV1 and peak improvement in inspiratory capacity (IC) [ Time Frame: Day 1 ]
    Day 1 timepoints for FEV1 and IC are measured over 2 hours

  • Improvement in pre-dose FEV1, peak FEV1, peak improvement in IC, and trough FEV1 [ Time Frame: Day 7 ]
    Day 7 time points for FEV1 are measured over 12 hours

  • Mean daily peak expiratory flow rate [ Time Frame: Day 1 through Day 7 ]

Enrollment: 118
Study Start Date: March 2010
Study Completion Date: November 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
