This is a phase 2, multicenter, randomized, double-blind, placebo-controlled, four-period, incomplete block design cross-over study using EP-101(SUN101) and open-label active controls (tiotropium bromide and ipratropium bromide). The study population will consist of subjects of 40-75 years of age with moderate to severe COPD. Approximately 133 subjects diagnosed with moderate to severe COPD will be enrolled in order to achieve minimum 105 subjects completing the study.
Following a run-in phase, each subject will be randomly assigned to one of 7 treatment sequences,(96 sequences when order of administration is considered), with each sequence comprised of four 7-day Treatment Periods. There will be a washout period of 7 days between each Treatment Period. Study visits will be conducted on Days 1 and 7 of each Treatment Period, with an overnight stay required in the clinic during these visits. A Final Study Visit will be conducted 7 days following the last study treatment.
During each Treatment Period, study treatments will be administered once daily (QD), except for ipratropium inhalation solution, which will be administered three times daily (TID). EP-101 (SUN101)active and placebo treatments will be administered using an investigational high-efficiency eFlow® nebulizer. Tiotropium bromide (Spiriva®) will be administered in an open-label manner via Handihaler® dry-powder inhaler (DPI). Ipratropium bromide inhalation solution will be administered in an open-label manner via general purpose nebulizer.
