Effectiveness of Fluticasone Furoate/ Umeclidinium/ Vilanterol (FF/UMEC/VI) Using the Connected Inhaler System (CIS) as Compared With Fluticasone Proprionate/ Salmeterol (FP/SAL) Plus Tiotropium (TIO) in Inadequately Controlled Asthma

Inclusion Criteria: * Subjects must have their own Android or iPhone operating system (IOS) mobile device (example given \[e.g.\] smart phone or tablet) and a data package suitable for the installation and running of the app and sending and receiving data. Data used by the CIS is approximately 1 megabyte (MB) per month as a maximum; this is less data than a 1 minute video streamed from YouTube (2MB). * Subjects must be willing and able to download the app on their personal mobile device and keep it turned on for the duration of the study. This will also require Bluetooth to be turned on for duration of the study. Subjects will also have to turn on mobile data for the app for the duration of study; unless travelling and when extra data roaming costs could be incurred. * Subjects must be 18 years of age or older at the time of signing the informed consent. * Subjects with a documented diagnosis of asthma by a respiratory physician or subjects with a documented asthma diagnosis by their general practitioner (GP) are required to have spirometry consistent with the diagnosis of asthma (e.g., reduced FEV1, reduced FEV1/forced vital capacity (FVC), or variable airflow obstruction) at or before Visit 0. * Subjects who are able to perform spirometry that conforms to American Thoracic Society/ European Respiratory Society(ATS/ERS) technical standards at Visit 0 or Visit 1. * Subjects are eligible if they require daily ICS/ long-acting beta-agonist (LABA) therapy (with a stable total daily dose of ICS of \>250 microgram per day \[mcg/day\] FP, or equivalent) for at least 4 weeks prior to screening. Dosing regimen (once or twice daily to equal the total daily dose) should be restricted to the current local product labels/treatment guidelines. * Subjects with inadequately controlled asthma (ACT total score \<20) despite ICS/LABA maintenance therapy at Visit 1. * Male or Female subjects will be included in the study. 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 for at least 5 days after the last dose of study treatment. The Investigator is responsible for ensuring that subject understands how to properly use these methods of contraception. * Capable of giving signed informed consent. Exclusion Criteria: * Subjects with current evidence of pneumonia, active tuberculosis, lung cancer, significant bronchiectasis, sarcoidosis, lung fibrosis, pulmonary hypertension, interstitial lung diseases, or other active pulmonary diseases including chronic obstructive pulmonary disease (COPD) or abnormalities other than asthma. * Subjects with historical or current evidence of uncontrolled or clinically significant disease. Significant is defined as any disease that, in the opinion of the Investigator, would put the safety of the subject at risk through participation (e.g. very low body mass index \[BMI\] or severely malnourished), or which would affect the efficacy or safety analysis if the disease/condition exacerbated during the study. * Subjects with any of the following at screening would be excluded: myocardial infarction or unstable angina in the last 6 months; unstable or life threatening cardiac arrhythmia requiring intervention in the last 3 months; New York Heart Association (NYHA) Class IV Heart failure. * Moderate or severe hepatic impairment in subjects receiving high dose ICS. * Subjects with a history of allergy or hypersensitivity to any corticosteroid, anticholinergic/ muscarinic receptor antagonist, beta2-agonist, lactose/milk protein or magnesium stearate are excluded from participation in this study. * Subjects with a medical condition such as narrow-angle glaucoma, urinary retention, prostatic hypertrophy or bladder neck obstruction should only be included if in the opinion of the Investigator the benefit outweighs the risk and that the condition would not contraindicate study participation. * Subjects with active uncontrolled psychiatric disease, intellectual deficiency, poor motivation or other conditions that will limit the validity of informed consent to participate in the study. * 30 days or within 5 drug half-lives of the investigational drug (whichever is longer). * Subjects who are medically unable to withhold their albuterol/salbutamol for the 6-hour period required prior to spirometry testing at each study visit. * Smokers will be excluded as follows: current smokers (defined as subjects who have used inhaled tobacco products within the 12 months prior to screening \[that is {i.e.}, cigarettes, e-cigarettes/vaping, cigars or pipe tobacco\]); former smokers with a smoking history of \>=10 pack years (e.g., \>=20 cigarettes/day for 10 years). * Subjects unable to comply with the study procedures due to infirmity, disability, or geographic location. * Study Investigators, sub-Investigators, study coordinators, employees of a participating Investigator or study site, or immediate family members of the aforementioned that is involved with this study. * In the opinion of the Investigator, any subject who is unable to read and/or would not be able to complete study related materials. * Subjects who have taken part in more than 1 clinical trial in the 12 months prior to Visit 1 and/or subjects who have taken part in any of the following clinical trials in the 12 months prior to Visit 1: a clinical trial including audio and/or visual reminders for the subject to take their study treatment; any clinical trial during the 4 weeks prior to Visit 1;GSK study 207040.
