Brief Summary:
A once-daily 'closed' triple FDC therapy of FF/UMEC/VI via a single ELLIPTA® dry powder inhaler (DPI) is being developed by GlaxoSmithKline (GSK) with the aim of providing a new treatment option for the management of asthma by improving lung function, health-related quality of life (HRQoL) and symptom control over established combination therapies. This is a phase III, multi-center, active-controlled, double-blind, parallel-group study to compare the efficacy, safety and tolerability of the FDC of FF/UMEC/VI with the FDC of FF/VI. This study has 5 phases: Pre-Screening (Visit 0), Screening/Run-in, Enrolment/Stabilization, Randomization/Treatment, and Follow up. At Visit 1 (Screening), subjects meeting all protocol defined inclusion/exclusion criteria will enter a 3-week run-in period and will receive fixed dose inhaled corticosteroid/long-acting beta agonist (ICS/LABA) (fluticasone/salmeterol, 250/50 micrograms (mcg), via the DISKUS® DPI) one inhalation twice a day. At Visit 2 (Enrolment), eligible subjects will be enrolled into the 2-week stabilization period to receive FF/VI (100/25 mcg via the ELLIPTA DPI once a day, in the morning). At the conclusion of the stabilization period (Visit 3), all subjects who meet the pre-defined randomization criteria will be randomized 1:1:1:1:1:1 during the treatment period to receive either FF/UMEC/VI (100/62.5/25 mcg; 200/62.5/25 mcg; 100/31.25/25 mcg; 200/31.25/25 mcg) or FF/VI (100/25 mcg; 200/25 mcg) via the ELLIPTA DPI once daily in the morning. The duration of the treatment period is variable but will be a minimum of 24 weeks and a maximum of 52 weeks. Subjects will have up to 6 on-treatment clinic visits scheduled at Visits 3, 4, 5, 6, 7 and 8/End of Study (EOS) (Weeks 0, 4, 12, 24, 36 and 52, respectively). A follow-up visit will be conducted approximately 7 days after the end of treatment period or, if applicable, after the early withdrawal visit. Subjects will be provided with short acting albuterol/salbutamol to be used on an as-needed basis (rescue medication) throughout the study. Approximately 2250 subjects will be randomized, with approximately 375 subjects randomized to each of the 6 double-blind treatment arms to ensure approximately 337 evaluable subjects per treatment arm.

Primary Outcome Measures :
  1. Mean Change From Baseline in Trough Forced Expiratory Volume in 1 Second (FEV1) at Week 24 [ Time Frame: Baseline (pre-dose at Day 1) and Week 24 ]
    FEV1 is a measure of lung function and is defined as the maximal volume of air that can be forcefully exhaled in one second. Trough FEV1 on treatment is defined as the highest FEV1 value obtained prior to the morning dose of investigational product. Baseline value is the last acceptable/borderline acceptable pre-dose FEV1 prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at Week 24 minus the Baseline value. Intent-to-Treat (ITT) Population comprised of all randomized participants, excluding those who were randomized in error, who did not receive the study drug. Treatment policy estimand was assessed, including all on- and post-treatment data. Different participants may have been analyzed at different time points; thus, overall number of participants analyzed reflects everyone in ITT Population without missing covariate information, with Baseline and at least one post-baseline measurement. Mixed Model Repeated Measures(MMRM) was used.


Secondary Outcome Measures :
  1. Annualized Rate of Moderate and Severe Asthma Exacerbations [ Time Frame: Up to Week 52 ]
    A moderate asthma exacerbation is considered to be a deterioration in asthma symptoms or in lung function, or increased rescue bronchodilator use lasting for at least 2 days or more, but not be severe enough to warrant systemic corticosteroid use (or a doubling or more of the maintenance systemic corticosteroid dose, if applicable) for 3 days or more and/or hospitalization. It is an event that, when recognized, should result in a temporary change in treatment, to prevent it from becoming severe. A severe asthma exacerbation is defined as the deterioration of asthma requiring the use of systemic corticosteroids (tablets,suspension or injection), or an increase from a stable maintenance dose (For participants receiving maintenance systemic corticosteroids, at least double the maintenance systemic corticosteroid dose for at least 3 days is required), for at least 3 days or an inpatient hospitalization or emergency department visit because of asthma, requiring systemic corticosteroids.

  2. Mean Change From Baseline in Clinic FEV1 at 3 Hours Post Study Treatment at Week 24 [ Time Frame: Baseline (pre-dose at Day 1) and 3 hours post dose at Week 24 ]
    FEV1 is a measure of lung function and is defined as the maximal volume of air that can be forcefully exhaled in one second. Baseline value is the last acceptable/borderline acceptable pre-dose FEV1 prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at Week 24 (recorded at 3 hours post dose) minus the Baseline value.

  3. Mean Change From Baseline in Asthma Control Questionnaire-7 (ACQ-7) Total Score at Week 24 [ Time Frame: Baseline (pre-dose at Day 1) and Week 24 ]
    The ACQ-7 consists of 7 attributes of asthma control, of which 6 to be self-completed by participant in a 6-item questionnaire, enquire about frequency and/or severity of symptoms over the previous week on: nocturnal awakening, symptoms on waking in the morning, activity limitation, shortness of breath, wheeze, and rescue medication use. The seventh attribute measures the lung function, which was included via pre-bronchodilator FEV1 % predicted value. All 7 items of ACQ have response on 0-6 ordinal scale (0=no impairment/limitation, 6=total impairment/limitation). The total score is calculated as the average of all non-missing item responses, ranges from 0 to 6. Higher score indicates worst symptoms. Treatment policy estimand was assessed, including all on- and post-treatment data. Baseline value was at randomization visit (pre-dose,Day 1). Change from Baseline was defined as value at Week 24 minus Baseline value.

  4. Mean Change From Baseline in Saint George's Respiratory Questionnaire (SGRQ) Total Score at Week 24 [ Time Frame: Baseline (pre-dose at Day 1) and Week 24 ]
    The SGRQ had 50 questions (scored from 0 to 100 where 0 indicates best and 100 indicates worst health) designed to measure quality of life (QoL) of participants with airway obstruction, measuring symptoms, impact, and activity. The questions are designed to be self-completed by the participant with a recall over the past 3 months. SGRQ total score was calculated by summing the pre-assigned weights of answers, dividing by the sum of the maximum weights for items in SGRQ and multiplying by 100. SGRQ total score ranges from 0 to 100 where 0 indicates best and 100 indicates worst health. A change of 4 points is considered a clinically relevant change. Treatment policy estimand was assessed, including all on- and post-treatment data. Baseline value was at randomization visit (pre-dose at Day 1). Change from Baseline value is the value at Week 24 minus the Baseline value.

  5. Mean Change From Baseline in Evaluating Respiratory Symptoms (E-RS) Total Score Over Weeks 21 to 24 (Inclusive) of the Treatment Period [ Time Frame: Baseline (14 days prior to randomization) and Weeks 21 to 24 ]
    The E-RS in Chronic Obstructive Pulmonary Disease (COPD) consists of 11 items. E-RS captures information related to respiratory symptoms, i.e. breathlessness, cough, sputum production, chest congestion and chest tightness. The E-RS was completed daily and data was derived by 4-weekly intervals, requiring at least 50% of data to be present during a period. 7 items are scored from 0 (not at all) to 4 (extreme) and 4 items are scored from 0 (not at all) to 3 (extreme). The E-RS total score was calculated by taking sum of all the items. The E-RS total score has a scoring range of 0 to 40, with higher scores indicating more severe respiratory symptoms. Treatment policy estimand was assessed, including all on- and post-treatment data. Baseline value was the mean value of 14 days prior to randomization. Change from Baseline was calculated as post-baseline value (mean of daily E-RS total scores during Week 21 to 24 ) minus Baseline value.

  6. Number of Participants With Any Serious Adverse Event (SAE) and Common (>=3%) Non-SAE [ Time Frame: Up to Week 52 ]
    Adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, events associated with liver injury and impaired liver function, or any other situation according to medical or scientific judgment were categorized as SAE. Number of participants with any SAE and common (>=3%) non-SAEs are presented.

  7. Number of Participants With Abnormal Electrocardiogram (ECG) Findings [ Time Frame: Up to Week 52 ]
    Twelve-lead ECGs were performed during the study using an automated ECG machine. All ECG measurements were made with the participant in a supine position having rested in this position for approximately 5 minutes before each reading. The number of participants with worst case post-Baseline abnormal ECG findings were reported.

  8. Mean Change From Baseline in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) at Week 24 [ Time Frame: Baseline (pre-dose at Day 1) and Week 24 ]
    Blood pressure (systolic and diastolic) was measured in the sitting position after approximately 5 minutes rest. Baseline value is the last acceptable/borderline acceptable value prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at the clinic visit minus the Baseline value. Different participants may have been analyzed at different time points; thus, overall number of participants analyzed reflects everyone in ITT Population without missing covariate information, with Baseline and at least one post-baseline measurement.

  9. Mean Change From Baseline in Pulse Rate at Week 24 [ Time Frame: Baseline (pre-dose at Day 1) and Week 24 ]
    Pulse Rate was measured in the sitting position after approximately 5 minutes rest. Baseline value is the last acceptable/borderline acceptable value prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at the clinic visit minus the Baseline value. Different participants may have been analyzed at different time points; thus, overall number of participants analyzed reflects everyone in ITT Population without missing covariate information, with Baseline and at least one post-baseline measurement.

  10. Number of Participants With Abnormal Clinical Chemistry Values [ Time Frame: Up to Week 52 ]
    Blood samples were collected for assessment of clinical chemistry parameters, which included albumin, alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), direct bilirubin, total bilirubin, calcium, creatinine, glucose, potassium, protein, sodium and urea. Abnormal laboratory results are categorized as high or low with respect to their normal ranges. Participants having High and Low values from normal ranges for any parameter at any time post-baseline visits are presented.

  11. Number of Participants With Abnormal Hematology Values [ Time Frame: Up to Week 52 ]
    Blood samples were collected for assessment of hematology parameters, which included Basophils, Eosinophils, Lymphocytes, Monocytes, Neutrophils, Erythrocytes, Hematocrit, Hemoglobin, Leukocytes, Platelets, Mean Corpuscular Hemoglobin (MCH) and Mean Corpuscular Volume (MCV). Abnormal laboratory results are categorized as high or low with respect to their normal ranges. Participants having High and Low values from normal ranges for any parameter at any time post-baseline visits are presented.

Inclusion Criteria for Screening

  • Age: 18 years of age or older at the time of signing the informed consent.
  • Diagnosis: Subjects with a diagnosis of asthma as defined by the National Institutes of Health at least one year prior to Visit 0.
  • Symptomatic: Subjects with inadequately controlled asthma (ACQ-6 score >=1.5) despite ICS/LABA maintenance therapy at Visit 1.
  • Asthma Control: In the 1 year prior to Visit 1

    • A documented healthcare contact for acute asthma symptoms or
    • A documented temporary change in asthma therapy for acute asthma symptoms, according to a pre-specified asthma action plan (or equivalent)
  • Current Asthma Maintenance Therapy: Subjects are eligible if they have required daily ICS/LABA for at least 12 weeks prior to Visit 0 with no changes to maintenance asthma medications during the 6 weeks immediately prior to Visit 0 (including no changes to a stable total dose of ICS of >250 mcg/day fluticasone proprionate [FP, or equivalent]).
  • Spirometry: A best pre-bronchodilator morning (ante meridian [AM]) FEV1 >=30% and <85% of the predicted normal value at Visit 1. Predicted values will be based upon the European Respiratory Society (ERS) Global Lung Function Initiative.
  • Reversibility of Disease: airway reversibility defined as >=12% and >=200 milliliter (mL) increase in FEV1 between 20 and 60 minutes following 4 inhalations of albuterol/salbutamol aerosol at Visit 1.
  • If the subject does not meet the above reversibility criteria at Visit 1 then the reversibility assessment may be repeated once within 7 days of Visit 1 if either criteria a) or b) are met: a) >=9% increase in FEV1 between 20 and 60 minutes following 4 inhalations of albuterol/salbutamol aerosol at Visit 1. b) Documented evidence of a reversibility assessment within 1 year prior to Visit 1 which demonstrated a post-bronchodilator increase in FEV1 of >=12% and >=200 mL.

Should the subject successfully demonstrate airway reversibility (defined as >=12% and >=200 mL increase in FEV1 between 20 and 60 minutes following 4 inhalations of albuterol/salbutamol aerosol) at the second attempt then, provided that all other eligibility criteria assessed at Visit 1 are met, the subject may enter the 3-week run-in period.

  • Short-Acting beta2 Agonists (SABAs): All subjects must be able to replace their current SABA inhaler with albuterol/salbutamol aerosol inhaler at Visit 1 as needed for the duration of the study. Subjects must be judged capable of withholding albuterol/salbutamol for at least 6 hours prior to study visits.
  • Male or eligible Female, defined as having documentation of non-reproductive potential or reproductive potential as follows:

A female subject is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin (hCG) test), not lactating, is not planning on becoming pregnant during the study and at least one of the following conditions applies: Non-reproductive potential defined as pre-menopausal females with documented tubal ligation or documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion or hysterectomy or documented bilateral oophorectomy; Postmenopausal defined as 12 months of spontaneous amenorrhea with an appropriate clinical profile (e.g., age appropriate, >45 years, in the absence of hormone replacement therapy). In questionable cases for women <60 years of age, a blood sample with simultaneous follicle stimulating hormone and estradiol falling into the central laboratory's postmenopausal reference range is confirmatory. Females under 60 years of age, who are on hormone replacement therapy (HRT) and whose menopausal status is in doubt, are required to use a highly effective method to avoid pregnancy if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment. For most forms of HRT, at least 2 to 4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, subjects can resume use of HRT during the study without use of a highly effective method to avoid pregnancy; Reproductive potential and agrees to follow one of the options listed in the Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) from the screening visit until after the last dose of study medication and completion of the follow-up visit. The Investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.

  • Informed Consent: Able to give written informed consent prior to participation in the study, which will include the ability to comply with the requirements and restrictions listed in the consent form and in this protocol. Subjects must be able to read, comprehend, and write at a level sufficient to complete study related materials.

Exclusion Criteria for Screening

  • Pneumonia: Chest X-ray documented pneumonia in the 6 weeks prior to Visit 1.
  • Asthma Exacerbation: Any asthma exacerbation requiring a change in maintenance asthma therapy in the 6 weeks prior to Visit 1. Note: Subjects requiring a temporary change in asthma therapy (e.g., oral corticosteroids or increased dose of ICS) to treat an exacerbation in the 6 weeks prior to Visit 1 are not explicitly excluded at Visit 1 provided that, at the Investigator's discretion, the subject's condition is stable after they have resumed their pre-exacerbation maintenance asthma therapy (without modification) and they are considered appropriate for enrolment into this study of up to 12 month's duration.
  • Chronic Obstructive Pulmonary Disease: Subjects with the diagnosis of chronic obstructive pulmonary disease, as per Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, including history of exposure to risk factors (i.e., especially tobacco smoke, occupational dusts and chemicals, smoke from home cooking and heating fuels) and a post-albuterol/salbutamol FEV1/Forced Vital Capacity (FVC) ratio of <0.70 and a post-albuterol/salbutamol FEV1 of =<70% of predicted normal values and onset of disease >=40 years of age.
  • Concurrent respiratory disorders: 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 or abnormalities other than asthma.
  • Risk Factors for Pneumonia: Immune suppression (e.g., human immunodeficiency virus, Lupus) or other risk factors for pneumonia (e.g., neurological disorders affecting control of the upper airway, such as Parkinson's Disease, Myasthenia Gravis).
  • Patients at potentially high risk (e.g., very low body mass index (BMI), severely malnourished, or very low FEV1) will only be included at the discretion of the Investigator.
  • Other diseases/abnormalities: Subjects with historical or current evidence of clinically significant cardiovascular, neurological, psychiatric, renal, hepatic, immunological, gastrointestinal, urogenital, nervous system, musculoskeletal, skin, sensory, endocrine (including uncontrolled diabetes or thyroid disease) or hematological abnormalities that are uncontrolled. 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.
  • Unstable liver disease as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices or persistent jaundice, cirrhosis, known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones). Note: Chronic stable hepatitis B and C are acceptable if the subject otherwise meets entry criteria.
  • Clinically significant Electrocardiogram abnormality: Evidence of a clinically significant abnormality in the 12-lead ECG performed during screening. The Investigator will determine the clinical significance of each abnormal ECG finding in relation to the subject's medical history and exclude subjects who would be at undue risk by participating in the trial. An abnormal and clinically significant finding is defined as a 12-lead tracing that is interpreted as, but not limited to, any of the following: Atrial fibrillation (AF) with rapid ventricular rate >120 Beats Per Minute (BPM); sustained or non-sustained ventricular tachycardia (VT); Second degree heart block Mobitz type II and third degree heart block (unless pacemaker or defibrillator had been inserted); QT interval corrected for heart rate by Fridericia's formula (QTcF) >=500 milliseconds (msec) in subjects with QRS <120 msec and QTcF >=530 msec in subjects with QRS >=120 msec.
  • Unstable or life threatening cardiac disease: Subjects with any of the following at Screening (Visit 1) 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.
  • Antimuscarinic effects: 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.
  • Cancer: Subjects with carcinoma that has not been in complete remission for at least 5 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 5 year waiting period if the subject has been considered cured by treatment.
  • Questionable validity of consent: 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.
  • Medication prior to spirometry: Subjects who are medically unable to withhold their albuterol/salbutamol for the 6-hour period required prior to spirometry testing at each study visit.
  • Tobacco Use: Subjects who are: Current smokers (defined as subjects who have used inhaled tobacco products within the 12 months prior to Visit 1 [i.e., cigarettes, e-cigarettes/vaping, cigars or pipe tobacco]) or former smokers with a smoking history of >=10 pack years (e.g., >=20 cigarettes/day for 10 years).
  • Drug/alcohol abuse: Subjects with a known or suspected history of alcohol or drug abuse within the last 2 years.
  • Allergy or Hypersensitivity: A history of allergy or hypersensitivity to any corticosteroid, anticholinergic/muscarinic receptor antagonist, beta2-agonist, lactose/milk protein or magnesium stearate.
  • Non-compliance: 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.
  • Affiliation with Investigator site: 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.
  • Inability to read: In the opinion of the Investigator, any subject who is unable to read and/or would not be able to complete study related materials.

Inclusion Criteria for Enrolment

  • Inadequately controlled asthma: Subjects with inadequately controlled asthma (ACQ-6 score >=1.5) at Visit 2.
  • Percent-predicted FEV1: A best pre-bronchodilator morning (AM) FEV1 >=30% and <90% of the predicted normal value at Visit 2. Predicted values will be based upon the ERS Global Lung Function Initiative
  • Liver function tests at Visit 1: alanine aminotransferase (ALT) <2 x upper limit of normal (ULN); alkaline phosphatase <=1.5xULN; bilirubin <=1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%)
  • Compliance with completion of the Daily eDiary reporting defined as completion of all questions/assessments on >=4 of the last 7 days during the run-in period.

Exclusion Criteria for Enrolment

  • Respiratory Infection: Occurrence of a culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus or middle ear during the run-in period that led to a change in asthma management or, in the opinion of the Investigator, is expected to affect the subject's asthma status or the subject's ability to participate in the study.
  • Severe asthma exacerbation: Evidence of a severe exacerbation during screening or the run-in period, defined as deterioration of asthma requiring the use of systemic corticosteroids (tablets, suspension, or injection) for at least 3 days or an in-patient hospitalization or emergency department visit due to asthma that required systemic corticosteroids.
  • Asthma medication: Changes in asthma medication (excluding run-in medication and albuterol/salbutamol inhalation aerosol provided at Visit 1).
  • Laboratory test abnormalities: Evidence of clinically significant abnormal laboratory tests during screening or run-in which are still abnormal upon repeat analysis and are not believed to be due to disease(s) present. Each Investigator will use his/her own discretion in determining the clinical significance of the abnormality.

Inclusion Criteria for Randomization

  • Compliance with completion of the Daily eDiary reporting defined as completion of all questions/assessments on >=4 of the last 7 days during the stabilization period.

Exclusion Criteria for Randomization

  • Respiratory Infection: Occurrence of a culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus or middle ear during the stabilization period that led to a change in asthma management or, in the opinion of the Investigator, is expected to affect the subject's asthma status or the subject's ability to participate in the study.
  • Severe asthma exacerbation: Evidence of a severe exacerbation during enrolment or the stabilization period, defined as deterioration of asthma requiring the use of systemic corticosteroids (tablets, suspension, or injection) for at least 3 days or an inpatient hospitalization or emergency department visit due to asthma that required systemic corticosteroids.
