Preference Attributes of ELLIPTA Dry Powder Inhaler (DPI) and HANDIHALER DPI in Subjects With Chronic Obstructive Pulmonary Disease (COPD)

Overview

This is a Phase IV multi-center, randomized, open-label, cross-over, placebo study in subjects with Chronic Obstructive Pulmonary Disease (COPD) to compare inhaler-specific preference attributes of two inhalers – ELLIPTA dry powder inhaler (DPI) and the HANDIHALER DPI. The primary objective of this study is to evaluate whether more subjects with COPD prefer the ELLIPTA inhaler to the HANDIHALER DPI based on the number of steps needed to take medication.

All subjects will use the ELLIPTA inhaler and the HANDIHALER inhaler in the corresponding treatment periods based on the randomisation scheme, and at the end of 2 periods, complete the inhaler preference questionnaire. Subjects will self-administer the inhalation once daily for 5-9 days in each treatment period.

This study will be placebo-only, and neither inhaler will contain active treatment. Subjects will continue their current COPD medication(s) as prescribed, and will follow up with their regular physician for their COPD healthcare during the study.

Approximately 211 subjects will be enrolled in the study.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Crossover Assignment

Interventions

  • Drug: Placebo ELLIPTA device
    • Placebo ELLIPTA is a DPI device containing powder for inhalation, to be inhaled orally once daily for 5-9 days. It contains two strips with 30 blisters per strip – one strip contains lactose monohydrate whereas the other strip contains lactose monohydrate blended with magnesium stearate.
  • Drug: Placebo capsules for use in HANDIHALER device
    • Placebo capsules contain lactose monohydrate in the form of powder for inhalation, to be used with the HANDIHALER inhaler as an oral inhalation once daily for 5-9 days.
  • Other: Inhaler Preference Questionnaire Version 1
    • Consists of 5 questions to assess subjects’ preference of device attributes and dosing regimens. The two versions of the questionnaire ask the same questions, but differ in the ordering of inhalers in their responses.
  • Other: Inhaler Preference Questionnaire Version 2
    • Consists of 5 questions to assess subjects’ preference of device attributes and dosing regimens. The two versions of the questionnaire ask the same questions, but differ in the ordering of inhalers in their responses.

Arms, Groups and Cohorts

  • Experimental: ELLIPTA – HANDIHALER; HANDIHALER Questionnaire Version 1
    • Subjects will be dispensed the ELLIPTA inhaler at Visit 1 to use during the first period (once daily for 5-9 days), and the HANDIHALER inhaler at Visit 2 to use during the second period (once daily for 5-9 days). At Visit 3, subjects will complete Version 1 of the inhaler preference questionnaire.
  • Experimental: ELLIPTA – HANDIHALER; Questionnaire Version 2
    • Subjects will be dispensed the ELLIPTA inhaler at Visit 1 to use during the first period (once daily for 5-9 days), and the HANDIHALER inhaler at Visit 2 to use during the second period (once daily for 5-9 days). At Visit 3, subjects will complete Version 2 of the inhaler preference questionnaire.
  • Experimental: HANDIHALER – ELLIPTA; Questionnaire Version 1
    • Subjects will be dispensed the HANDIHALER inhaler at Visit 1 to use during the first period (once daily for 5-9 days), and the ELLIPTA inhaler at Visit 2 to use during the second period (once daily for 5-9 days). At Visit 3, subjects will complete Version 1 of the inhaler preference questionnaire.
  • Experimental: HANDIHALER – ELLIPTA; Questionnaire Version 2
    • Subjects will be dispensed the HANDIHALER inhaler at Visit 1 to use during the first period (once daily for 5-9 days), and the ELLIPTA inhaler at Visit 2 to use during the second period (once daily for 5-9 days). At Visit 3, subjects will complete Version 2 of the inhaler preference questionnaire.

Clinical Trial Outcome Measures

Primary Measures

  • Percentage of Participants Preferring the Inhaler Based on the Number of Steps Needed to Take the COPD Medication
    • Time Frame: Up to 18 days
    • Preference between ELLIPTA inhaler and Handihaler based on the number of steps needed to take the medication was assessed by the inhaler preference questionnaire at Visit 3 or Early Withdrawal (EW) visit. The responses were analyzed using a Cochran-Mantel-Haenszel test, adjusted for study inhaler use sequence and preference questionnaire version. The analysis was performed on the Modified Intent-to-treat (ITT) Population comprised of all participants in the ITT Population (comprised all randomized participants who received 1 dose of at least 1 study inhaler) who completed at least one question from the 5 preference questions.

Secondary Measures

  • Percentage of Participants Preferring the Inhaler Based on How Easy it Was to Tell How Many Doses Were Left
    • Time Frame: Up to 18 days
    • Preference between ELLIPTA inhaler and Handihaler based on how easy it was to tell how many doses were left was assessed by the inhaler preference questionnaire at Visit 3 or EW visit. The responses were analyzed using a Cochran-Mantel-Haenszel test, adjusted for study inhaler use sequence and preference questionnaire version.
  • Percentage of Participants Preferring the Inhaler Based on the Size of the Inhaler
    • Time Frame: Up to 18 days
    • Preference between ELLIPTA inhaler and HandiHaler based on the size of the inhaler was assessed by the inhaler preference questionnaire at Visit 3 or EW visit. The responses were analyzed using a Cochran-Mantel-Haenszel test, adjusted for study inhaler use sequence and preference questionnaire version.
