- Informed Consent: A signed and dated written informed consent prior to study
participation.

- Age: Subjects 40 years of age or older at Visit 1.

- Gender: Male or female subjects.

- A female is eligible to enter and participate in the study if she is of:

- Non-child bearing potential (i.e., physiologically incapable of becoming pregnant,
including any female who is post-menopausal or surgically sterile). Surgically
sterile females are defined as those with a documented hysterectomy and/or bilateral
oophorectomy or tubal ligation. Post-menopausal females are defined as being
amenorrhoeic for greater than 1 year with an appropriate clinical profile, e.g., age
appropriate, >45 years, in the absence of hormone replacement therapy.

OR

- Child bearing potential, has a negative pregnancy test at screening, and agrees to
one of the following acceptable contraceptive methods used consistently and correctly
(i.e., in accordance with the approved product label and the instructions of the
physician for the duration of the study - screening to follow-up contact):

- Abstinence

- Oral Contraceptive, either combined or progestogen alone

- Injectable progestogen

- Implants of levonorgestrel

- Estrogenic vaginal ring

- Percutaneous contraceptive patches

- Intrauterine device (IUD) or intrauterine system (IUS) that meets the SOP
effectiveness criteria as stated in the product label

- Male partner sterilization (vasectomy with documentation of azoospermia) prior to the
female subject's entry into the study, and this male is the sole partner for that
subject. For this definition, "documented" refers to the outcome of the
investigator's/designee's medical examination of the subject or review of the
subject's medical history for study eligibility, as obtained via a verbal interview
with the subject or from the subject's medical records.

- Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps)
with a vaginal spermicidal agent (foam/gel/film/cream/suppository)

- Diagnosis: An established clinical history of COPD in accordance with the definition
by the American Thoracic Society/European Respiratory Society.

- Smoking History: Current or former cigarette smokers with a history of cigarette
smoking of >=10 pack-years [number of pack years = (number of cigarettes per day /
20) x number of years smoked (e.g., 20 cigarettes per day for 10 years, or 10
cigarettes per day for 20 years)]. Former smokers are defined as those who have
stopped smoking for at least 6 months prior to Visit 1. Pipe and/or cigar use cannot
be used to calculate pack year history.

- Severity of Disease: A pre and post-albuterol/salbutamol FEV1/FVC ratio of <0.70 and
a pre and post-albuterol/salbutamol FEV1 of <=70% of predicted normal values at Visit
1 (Screening) calculated using Nutrition Health and Examination Survey (NHANES) III
reference equations.

- Dyspnea: A score of >=2 on the mMRC Dyspnea Scale at Visit 1.

- QTc Criteria:

- QTc(F) <450 milliseconds (msec) or

- QTc(F) <480msec for patients with QRS duration >=120msec

- The QTc is the QT interval corrected for heart rate according to either Bazett's
formula (QTcB), Fridericia's formula (QTcF), or another method, machine or manual
overread.

- For subject eligibility and withdrawal, QTcF will be used.

- For purposes of data analysis, QTcF will be used as primary.

- The QTc should be based on single or averaged QTc values of triplicate
electrocardiograms (ECGs) obtained over a brief recording period.

Exclusion Criteria:

- Pregnancy: Women who are pregnant or lactating or are planning on becoming pregnant
during the study.

- Asthma: A current diagnosis of asthma.

- Other Respiratory Disorders: Known alpha-1 antitrypsin deficiency, active lung
infections (such as tuberculosis), and lung cancer are absolute exclusionary
conditions. A subject who, in the opinion of the investigator, has any other
significant respiratory conditions in addition to COPD should be excluded. Examples
may include clinically significant bronchiectasis, pulmonary hypertension,
sarcoidosis, or interstitial lung disease.

- Other Diseases/Abnormalities: Subjects with historical or current evidence of
clinically significant cardiovascular, neurological, psychiatric, renal, hepatic,
immunological, endocrine (including uncontrolled diabetes or thyroid disease) or
hematological abnormalities that are uncontrolled and/or a previous history of cancer
in remission for <5 years prior to Visit 1 (localized carcinoma of the skin that has
been resected for cure is not exclusionary). Significant is defined as any disease
that, in the opinion of the investigator, would put the safety of the subject at risk
through participation, or which would affect the efficacy or safety analysis if the
disease/condition exacerbated during the study.

- Contraindications: Any history of allergy or hypersensitivity to any
anticholinergic/muscarinic receptor antagonist, beta2-agonist, sympathomimetic,
corticosteroid (intranasal, inhaled or systemic) lactose/milk protein or magnesium
stearate, or a medical condition such as narrow-angle glaucoma, prostatic hypertrophy
or bladder neck obstruction, that, in the opinion of the study physician
contraindicates study participation or use of an inhaled Long acting muscarinic
antagonist (LAMA), Long acting beta agonist (LABA) or Inhaled corticosteroids (ICS).

- Hospitalization: Hospitalization for COPD or pneumonia within 12 weeks prior to Visit
1.

- Lower respiratory tract infection: Subjects with lower respiratory tract infection
that required the use of antibiotics within 6 weeks prior to Visit 1.

- Lung Resection: Subjects with lung volume reduction surgery within the 12 months
prior to Visit 1.

- 12-Lead ECG: An abnormal and clinical significant ECG finding from the 12-lead ECG
conducted at Visit 1. Investigators will be provided with ECG reviews conducted by a
centralized independent cardiologist to assist in evaluation of subject eligibility.
The study investigator will determine the medical significance of any ECG
abnormalities.

discussion with the Medical Monitor, the investigator may have the option to verify
the abnormal lab result prior to Visit2
