A Randomized Study, Comparing Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC /VI) Single Inhaler Triple Therapy, Versus Multiple Inhaler Therapy (Budesonide/Formoterol Plus Tiotropium) in Subjects With Chronic Obstructive Pulmonary Disease (COPD)

Inclusion Criteria

• Subjects must be capable of giving signed informed consent prior to study start.
• Only outpatient subjects will be included
• Subjects (male or female) must be 40 years of age or older at Screening (Visit 1). A female subject is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: Not a woman of childbearing potential (WOCBP) or a WOCBP who agrees to follow the contraceptive guidance during the treatment period and until safety follow-up contact after the last dose of study treatment
• An established clinical history of COPD in accordance with the definition by the American Thoracic Society/European Respiratory Society
• Current or former cigarette smokers with a history of cigarette smoking of >=10 pack-years at Screening (Visit 1) [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)]. Previous smokers are defined as those who have stopped smoking for at least 6 months prior to Visit 1.
• Subjects with a score of >=10 on the COPD Assessment Test (CAT) at Screening (Visit 1)
• Subjects must demonstrate a post-bronchodilator FEV1 =2 moderate exacerbations or one severe (hospitalized) exacerbation in the previous 12 months. Subjects must also have a measured post albuterol/salbutamol FEV1/forced vital capacity (FVC) ratio of 2 times Upper Limit of Normal (ULN); and bilirubin >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin 120 beats per minute (BPM); ii) Sustained and non-sustained Ventricular tachycardia (VT); iii). Second degree heart block Mobitz type II and third degree heart block (unless pacemaker or defibrillator had been inserted); iv) QT interval corrected for heart rate by Fridericia's formula (QTcF) >=500 milliseconds (msec) in subjects with QRS =530 msec in subjects with QRS >=120 msec.
• A history of allergy or hypersensitivity to any corticosteroid, anticholinergic/muscarinic receptor antagonist, beta2-agonist, 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 Investigator, contraindicates study participation.
• Subjects with carcinoma that has not been in complete remission for at least 3 years. Subjects who have had carcinoma in situ of the cervix, squamous cell carcinoma and basal cell carcinoma of the skin would not be excluded based on the 3 year waiting period if the subject has been considered cured by treatment.
• Use of long-term oxygen therapy (LTOT) described as resting oxygen therapy >3 liters per minute (L/min) at screening (Oxygen use <=3 L/min flow is not exclusionary)
• Subjects who are medically unable to withhold their albuterol/salbutamol for the 4-hour period required prior to spirometry testing at each study visit
• Subjects who have participated in the acute phase of a Pulmonary Rehabilitation Programme within 4 weeks prior to screening or subjects who plan to enter the acute phase of a Pulmonary Rehabilitation Program during the study. Subjects who are in the maintenance phase of a Pulmonary Rehabilitation Program are not excluded.
• Subjects with a known or suspected history of alcohol or drug abuse within the last 2 years
• Subjects at risk of non-compliance, or unable to comply with the study procedures. Any infirmity, disability, or geographic location that would limit compliance for scheduled visits
• Subjects with a history of psychiatric disease, intellectual deficiency, poor motivation or other conditions that will limit the validity of informed consent to participate in the study
• Study Investigators, sub-Investigators, coordinators, employees of a participating Investigator or study site, or immediate family members of the aforementioned that is involved with this study
