4. Women of child-bearing potential (WOCBP) must have a negative pregnancy test at the screening visit and agree to avoid becoming pregnant for the duration of study by using adequate contraception at study entry and throughout the trial. WOCBP will be advised to notify the Investigator of any change in their pregnancy status. WOCBP include: any female who has experienced menarche and is not post-menopausal (defined as amenorrhea for at least 12 consecutive months), or has not undergone surgical sterilization (hysterectomy, bilateral oophorectomy, or bilateral tubal ligation).

2. Clinically significant abnormal chest x-ray (CXR) (within the past 12 months) diagnostic of active/significant disease other than COPD
3. Evidence of any unstable or clinically significant hematopoietic, malignant, cardiovascular, hepatic, renal, neurologic, psychiatric, autoimmune disorder, or condition or disease other than COPD that, in the opinion of the Investigator, could place the subject at increased risk of complications, interfere with study participation, or confound any of the study objectives
4. Subjects who had radiation or chemotherapy within the previous 12 months
5. An abnormal laboratory test at screening deemed clinically significant and exclusionary by the Investigator
6. A history of hypersensitivity to study drugs or their components, including albuterol rescue -
