3. A measured post-bronchodilator (albuterol 360 mcg) forced expiratory volume in 1 second (FEV1) ≥30% and <80% of predicted normal at the SV. Predicted normal will be determined using National Health and Nutrition Examination Survey (NHANES) III standard values for Caucasians, African Americans and Mexican-Americans with adjustments to predicted values made for Asian American patients.

4. A measured post-bronchodilator (albuterol 360 mcg) FEV1/forced vital capacity (FVC) <0.70 at the SV.

5. A minimum body weight of 40 kg. (Note: For patients participating in the pharmacokinetic [PK] sub study a minimum body weight of 50 kg is required.)

6. If female, is currently not pregnant, breast feeding, or attempting to become pregnant (for 4 weeks before the SV and throughout the duration of the study), and is of non-childbearing potential, defined as:

• ≥1 year post-menopausal (6 months of spontaneous amenorrhea is permitted, provided there is a local record of serum follicle stimulating hormone >40 mIU/mL and this is source documented) or

• Surgically sterile (bilateral tubal ligation, bilateral oophorectomy, salpingectomy, or hysterectomy)

Or is of childbearing potential, has a negative serum pregnancy test, and is willing to commit to using a consistent and acceptable method of birth control, as defined below, for the duration of the study:

• Systemic contraception used for ≥1 month prior to screening, including birth control pills, transdermal patch, vaginal ring, implants, or injectables or

• Double barrier methods (spermicide with any of the following: condoms, cervical cap, diaphragm, and vaginal contraceptive film) or

• Intrauterine device (IUD) with a low failure rate defined as <1% per year (use of copper IUDs is not acceptable) Or is of childbearing potential and is not sexually active, has a negative serum pregnancy test, and, in the event the patient becomes sexually active, is willing to commit to using a consistent and acceptable method of birth control, as defined above, for the duration of the study. At the discretion of the investigator, total abstinence is acceptable in cases where the age, career (eg, priest), lifestyle, and/or sexual orientation of the patient ensures compliance.

7. Current or ex-smoker with ≥10 pack-year smoking history (number of cigarette packs smoked per day multiplied by the number of years smoked; eg, 2 packs/day for 3 years equals a 6 pack-year history).

8. Patient is free of any other medical conditions or concomitant treatment that could interfere with study conduct, influence the interpretation of study observations/results, or put the patient at increased risk during the study.

9. Able to perform technically acceptable and reproducible spirometry per American Thoracic Society/European Respiratory Society (ATS/ERS) 2005 guidelines and study guidelines, as defined in the protocol and study reference manual; this includes able to tolerate withdrawal of applicable medications during required spirometry assessments.

10. Able to perform acceptable peak expiratory flow measurements.

11. Able to maintain records (patient daily diary) during the study period as required by the protocol.

12. Able to demonstrate the proper inhalation techniques required for correct use of all delivery devices (BAI and dry powder inhaler [DPI]) required in the study.

13. Capable of understanding the requirements, risks, and benefits of study participation, and, as judged by the investigator, capable of giving informed consent and being compliant with all study requirements.

Exclusion Criteria:

Chronic Obstructive Pulmonary Disease

Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the patient at risk through participation, or which could affect the endpoint analysis if the disease/condition worsened during the study.

3. History of and/or current diagnosis of asthma.

4. History of a life-threatening COPD exacerbation - defined for this protocol as a COPD episode that required intubation or was associated with respiratory arrest.

5. Thoracotomy with pulmonary resection.

6. Current congestive heart failure, history or current evidence of myocardial infarction (within 1 year of the SV), or current history of active ischemic heart disease (exertional or intermittent angina).

7. History or current evidence of clinically significant cardiac arrhythmia or abnormality, including a diagnosis on screening ECG. Findings that are always considered clinically significant and will exclude the patient from study participation include, but are not limited to, the following:

• ventricular rate <45 beats per minute (bpm) or >100 bpm

• PR interval >240 msec

• evidence of 2nd- or 3rd-degree atrioventricular block (excluding MobitzI)

• evidence of supraventricular or ventricular ectopy or arrhythmias

• corrected QT interval (QTc) (Bazett's or Fridericia's method) >500 msec
