To Assess the Efficacy and Safety of PT010 Compared to PT009 in Subjects With Moderate to Very Severe Chronic Obstructive Pulmonary Disease

A Randomized, Double-Blind, Parallel-Group, 12-Week, Chronic Dosing, Multi-Center Study to Assess the Efficacy and Safety of PT010 Compared to PT009 in Subjects With Moderate to Very Severe Chronic Obstructive Pulmonary Disease

This is a 12-week chronic-dosing study to assess the efficacy and safety of BGF MDI compared to BFF MDI in subjects with moderate to very severe COPD.

This is a multicenter, randomized, double-blind, parallel-group, 12-week chronic-dosing study to assess the efficacy and safety of BGF MDI compared to BFF MDI in subjects with moderate to very severe COPD. The study has a total of 7 visits over a Screening Period of up to 28 days and a Treatment Period of 12 weeks followed by a telephone follow-up call 14 days after the last dose of study drug.

Key Inclusion Criteria:

• Signed Informed Consent
• Subjects with an established clinical history of COPD
• Forced expiratory volume in 1 second (FEV1)/Forced vital capacity (FVC) ratio must be <0.70 and FEV1 must be <80% predicted normal value
• All subjects must have been on 2 or more inhaled maintenance therapies for the management of their COPD for at least 6 weeks prior to Screening
• Current or former smokers with a history of at least 10 pack-years of cigarette smoking
• Women of Non-childbearing potential
• Women of childbearing potential and sexually active agree to prevent pregnancy by using acceptable contraceptive methods consistently

• Women who are pregnant or lactating, or are planning to become pregnant during the course of the study, or women of childbearing potential who are not using an acceptable method of contraception
• Current diagnosis of asthma
• Uncontrolled sleep apnea
• Other Serious Respiratory Disorders
• Hospitalized due to poorly controlled COPD within 6 weeks
• Poorly Controlled COPD
