Exclusion Criteria: * Smoking history ≥ 10 pack-years. Ex-smokers are eligible for inclusion if they quit smoking for at least 6 months prior to Visit 1. * Diagnosed with Chronic Obstructive Pulmonary Disease (COPD). * FEV1 \< 70% of predicted at baseline or \< 1.5 liters. * An asthma attack/exacerbation requiring systemic steroids or hospitalization or emergency room visit within 6 weeks of Visit 1. * Respiratory tract infection or clinically significant asthma worsening as defined by Investigator within 4 weeks prior to Visit 1. * Ever required intubation for a severe asthma attack/exacerbation. * Presence of clinical condition which is likely to be worsened by ICS administration (e.g. glaucoma, cataract and fragility fractures). * Treated with LAMA for asthma within 3 months prior to Visit 1. * Known with narrow-angle glaucoma, symptomatic benign prostatic hyperplasia (BPH) or bladder-neck obstruction or severe renal impairment or urinary retention. * Known with any chronic conditions affecting the upper respiratory tract (e.g. chronic sinusitis or polyposis nasi) which in the opinion of the investigator may interfere with the study evaluation or optimal participation in the study. Allergic rhinitis is allowed. * History of chronic lung diseases other than asthma, including (but not limited to) sarcoidosis, interstitial lung disease, cystic fibrosis, clinically significant bronchiectasis and active tuberculosis. * Uncontrolled Type I or Type II diabetes. * Clinically significant laboratory abnormality at Visit 1. * Use of other investigational drugs within 30 days or 5 half-lives of enrollment, until the expected pharmacodynamics effect has returned to baseline, whichever is longer. * Clinically significant condition such as (but not limited to) unstable ischemic heart disease, New York Heart Association (NYHA) Class III/IV left ventricular failure, arrhythmia, uncontrolled hypertension, cerebrovascular disease, psychiatric disease, neurodegenerative diseases, or other neurological disease, uncontrolled hypo- and hyperthyroidism and other autoimmune diseases, hypokalemia, hyper adrenergic state, or ophthalmologic disorder or patients with a medical condition that might compromise patient safety or compliance, interfere with evaluation, or preclude completion of the study. * Diagnosis of paroxysmal (e.g., intermittent) atrial fibrillation. * History of myocardial infarction within 12 months prior to Visit 1. * Concomitant use of agents known to prolong the QT interval unless it can be permanently discontinued for the duration of study. * History of long QT syndrome or QTc measured at Visit 1 (Fridericia method) is prolonged (\> 450 msec for males and \> 460 msec for females). * Clinically significant ECG abnormality at Visit 1. * History of malignancy of any organ system (other than localized basal cell carcinoma of the skin or in-situ cervical cancer), within the past 5 years, regardless of whether there is evidence of local recurrence or metastases. * History of hypersensitivity to lactose, any of the study drugs or its excipients, or to similar drugs within the class including untoward reactions to sympathomimetic amines or inhaled medication or any component thereof. * On maintenance immunotherapy (desensitization) for allergies for less than 3 months prior to Visit 1 or patients on Maintenance Immunotherapy for more than 3 months prior to Visit 1 but expected to change throughout the course of the study. * Unable to use the Breezhaler dry powder inhaler or a metered dose inhaler. * History of alcohol or other substance abuse that based on judgement of the investigator would interfere with study conduct. * Known history of non-compliance to medication. * Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test. * Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing of study treatment and for 5-times the terminal half-life after stopping medication.
