A Phase III Parallel Group Study, Comparing the Efficacy, Safety and Tolerability of the Fixed Dose Combination (FDC) of Fluticasone Furoate+Umeclidinium Bromide+Vilanterol (FF/UMEC/VI) With the FDC of FF/VI in Subjects With Inadequately Controlled Asthma

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.

DRUG

FF/UMEC/VI (100/62.5/25) mcg

Dry white powder delivered via the ELLIPTA DPI (one inhalation, QD in the morning). The ELLIPTA DPI holds 2 individual blister strips with 30 blisters on each strip: the first strip contains FF 100 mcg in each blister and the second strip contains UMEC 62.5 mcg and VI 25 mcg in each blister.

DRUG

FF/UMEC/VI (200/31.25/25) mcg

Dry white powder delivered via the ELLIPTA DPI (one inhalation, QD in the morning). The ELLIPTA DPI holds 2 individual blister strips with 30 blisters on each strip: the first strip contains FF 200 mcg in each blister and the second strip contains UMEC 31.25 mcg and VI 25 mcg in each blister.

DRUG

FF/UMEC/VI (200/62.5/25) mcg

Dry white powder delivered via the ELLIPTA DPI (one inhalation, QD in the morning). The ELLIPTA DPI holds 2 individual blister strips with 30 blisters on each strip: the first strip contains FF 200 mcg in each blister and the second strip contains UMEC 62.5 mcg and VI 25 mcg in each blister.

DRUG

FF/VI (100/25) mcg

Dry white powder delivered via the ELLIPTA DPI (one inhalation, QD in the morning). The ELLIPTA DPI holds 2 individual blister strips with 30 blisters on each strip: the first strip contains FF 100 mcg in each blister and the second strip contains VI 25 mcg in each blister.

DRUG

FF/VI (200/25) mcg

Dry white powder delivered via the ELLIPTA DPI (one inhalation, QD in the morning). The ELLIPTA DPI holds 2 individual blister strips with 30 blisters on each strip: the first strip contains FF 200 mcg in each blister and the second strip contains VI 25 mcg in each blister.

DRUG

Fluticasone/salmeterol (FSC)

Dry white powder delivered via the DISKUS DPI (one inhalation twice daily: one in the morning and one in the evening). The DISKUS DPI holds a strip of 60 blisters; each blister contains FP 250 mcg and 50 mcg of salmeterol.

DRUG

Albuterol/salbutamol

This is a rescue medication administered via metered-dose inhaler (MDI) which will be used when needed during the study.

DEVICE

ELLIPTA DPI

The ELLIPTA device will be used during the stabilization period and the treatment period. The ELLIPTA DPI is a moulded plastic two-sided device that can hold two individual blister strips which contain powder formulation for oral inhalation.

DEVICE

DISKUS DPI

The DISKUS device will be used during the run-in period. The DISKUS DPI is a plastic inhalation delivery system containing a single-foil blister strip of a powder formulation of FSC for oral inhalation.

DEVICE

METERED-DOSE INHALER (MDI)

Albuterol/salbutamol (rescue medication) will be delivered via metered-dose inhaler (MDI) will be used for reversibility testing.
