Brief summary

This randomized, cross over study aims to find out the benefits of delivering triple therapy using a single ELLIPTA® DPI (fixed-dose combination triple therapy) versus delivering triple therapy using two different types of inhalers (open triple therapy) including DISKUS® with HandiHaler® to subjects with COPD. Correct inhaler use, critical errors and performance attributes will also be assessed. Approximately 240 subjects with COPD will be randomized in the study. The study will be conducted in 3 visits and will be completed in approximately 56 days. At Visit 1 (Day 1) and Visit 2 (Day 28) subjects will be randomized to receive a placebo ELLIPTA inhaler once daily (QD) or a placebo DISKUS twice daily (BID) with placebo HandiHaler QD inhaler in 1:1 ratio in a cross-over manner for the study period (28 days for each period). At Visit 3 (Day 56), subjects will be asked to complete preference questionnaire 1 or 2. There will be no active treatment and subjects will continue to take their own prescribed COPD maintenance and rescue medication during the entire study period.

Interventions

DEVICEELLIPTA placebo DPI

ELLIPTA is a dry powder inhaler used via oral route. It will be a placebo DPI with two strips with 30 blisters per strip. First strip will contain lactose monohydrate and the second strip will contain lactose monohydrate blended with magnesium stearate.

DEVICEDISKUS placebo DPI

DISKUS is a dry powder inhaler used via oral route. It will be a placebo DPI with one blister strip that will contain lactose monohydrate.

DEVICEHandiHaler placebo DPI

HandiHaler is a dry powder inhaler used via oral route. It will be a DPI with placebo capsules that will contain lactose monohydrate.

OTHERInhaler preference questionnaires

Preference questionnaires will be given to subjects to understand the inhaler preference. There will be 2 types of questionnaire, preference questionnaires 1 and 2, which will be randomized at visit 3 (Day 56).

Recruitment details

This is a randomized, multi-center, open-label study comparing placebo ELLIPTA with placebo DISKUS + HandiHaler to assess correct inhaler use in participants with Chronic Obstructive Pulmonary Disease (COPD). A total of 17 centers across United States participated in the study.

Pre-assignment details

Out of 240 randomized participants (par), 239 entered the study as 1 par was randomized in error. In order to minimize potential bias the order of placebo devices & order of responses, in preference questionnaire (PQ), was randomized in a crossover design. All par on study received placebo only & participant flow reflects this as the only treatment

Number of Errors for Each Treatment Group in Participants With One or More Errors After 28 Days of Use (Primary Estimand: Hypothetical)

Participants were provided with the PIL, explaining correct use of the inhaler. Overall error includes both critical and non-critical errors. Assessment of errors was conducted by HCP trained in the correct inhaler use of the three inhalers based on the checklist of errors. Primary estimand is the treatment effect estimated in participants who stayed on their randomised study device sequence and did not change their standard COPD maintenance medication device to one delivered via ELLIPTA, DISKUS or HANDIHALER, throughout both 28 day treatment periods. The participant could attend the visit without the device/s they were randomised to, in which case correct use cannot be assessed as described in the protocol. For primary estimand, a sensitivity analysis using Cochran-Mantel-Haenszel test was performed on participants with discordant results. Only those participants who completed error assessments for both randomized treatment groups and experienced no intercurrent events were included.

Time frame: Up to Day 56

Population: ITT Population. Only those participants with data available at specified time point were analyzed.

Number of Participants With Atleast One Critical Error After 28 Days of Each Treatment Group Use (Primary Estimand: Hypothetical)

A critical error was defined as an error that was most likely to result in no, or a significantly reduced amount, of medication being inhaled by the participant. Primary estimand is the treatment effect estimated in participants who stayed on their randomised study device sequence and did not change their standard COPD maintenance medication device to one delivered via ELLIPTA, DISKUS or HANDIHALER, throughout both 28 day treatment periods.

Supplementary estimand estimated the composite effect of initial randomized treatment. A sensitivity analysis using the Cochran-Mantel-Haenszel test was performed on participants with discordant results. Participants who withdrew during period 2 were included in the analysis using early withdrawal data where available or imputation otherwise. Participants who experienced an intercurrent event in Period 1 were excluded from the analysis.
