About this study

Official title: Qualitative Research to Support Ellipta Ease-of-Use Questions in Pediatric Patients With Asthma

A range of devices has been developed to administer inhaled therapy for asthma, including dry powder inhaler (DPI) devices. ELLIPTA is a DPI that is preloaded with a drug therapy to treat asthmatic subjects. The objective of this study is to revise ease of use items developed for adults to be appropriate for completion by pediatric subjects in future clinical trials and to evaluate the newly developed items in subjects with asthma aged 5 to 11 years and their caregivers. This is a cross-sectional, qualitative study that will involve pediatric subjects with asthma who are currently using an asthma maintenance inhaler and their caregivers. Two rounds of repetitive cognitive interviews will be conducted with 16 subjects in each interview set. Each interview will last approximately 45 minutes. Data provided by pediatric subjects and their caregivers during interview will be collected as field notes and audio recordings which will be transcribed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Interviewer administered version of ease of use itemsOther

    The adult ease of use items will be modified to incorporate language appropriate for pediatric subjects. The interview will be administered by trained clinic-staff for subjects aged 5 to 7 years and those aged 8 to 11 years having difficulty in reading.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Pediatric Participants With Problems Understanding Item Wording-Round 1 Interviews

    The items for pediatric participants were developed to assess the concepts of overall ease of use of ELLIPTA and ease of evaluating remaining doses in inhaler. Pediatric participants aged 5 to 7 years were required to complete the interviewer-administered version and participants aged 8 to 11 years were administered self-completed version. Round 1 of the interviews evaluated 3 items to evaluate ease of use of inhaler (Items 1a, 1b and 1c), 3 items to assess the ease in evaluating remaining doses (Items 2a, 2b, 2c) and one item to assess if the pediatric participants could compare different types of inhalers (Item 3). The number of participants who had problems in understanding the item wordings has been presented. No statistical analyses were conducted for this qualitative study.

    Measured: Up to 45 minutes

  2. Number of Pediatric Participants With Difficulty Providing Responses to Items-Round 1 Interviews

    Round 1 of the interviews evaluated 3 items to evaluate ease of use of inhaler (Items 1a, 1b and 1c) and 3 items to assess the ease in evaluating remaining doses (Items 2a, 2b, 2c). Three response options were developed for these two concepts: Item 1a/2a-a verbal response scale with four options (Very easy, easy, hard, very hard); Item 1b/2b-the same four verbal response options accompanied by illustrations of faces for each verbal response; and Item 1c/2c-a verbal response scale with two options (Yes, No). The number of participants who had difficulty in providing item responses has been presented.

    Measured: Up to 45 minutes

  3. Number of Pediatric Participants With Difficulty in Distinguishing Between the Item Responses-Round 1 Interviews

    Round 1 of the interviews evaluated 3 items to evaluate ease of use of inhaler (Items 1a, 1b and 1c), 3 items to assess the ease in evaluating remaining doses (Items 2a, 2b, 2c) and one item to understand if the participants could compare different types of inhalers. Three response options were developed to assess ease of inhaler use and ease of evaluating remaining doses: Item 1a/2a-a verbal response scale with four options (Very easy, easy, hard, very hard); Item 1b/2b-the same four verbal response options accompanied by illustrations of faces for each verbal response; and Item 1c/2c-a verbal response scale with two options (Yes, No). Item 3 consisted of 3 response options (Yes, No, The same). The number of participants who had difficulty in distinguishing item responses has been presented.

    Measured: Up to 45 minutes

  4. Number of Caregiver Participants Who Had Difficulty Providing Responses to Caregiver Items-Round 1 Interviews

    Round 1 of the interviews for caregiver participants evaluated the concepts of ease of evaluating remaining doses (Item 1) and the likelihood of requesting inhaler from their child's physician (Item 2). A response scale with four options was developed for each item: Item 1 (Very easy, Easy, Difficult, Very difficult) and Item 2 (Very likely, Likely, Unlikely, Very unlikely). The number of caregivers who had difficulty in providing responses to caregiver items has been reported.

    Measured: Up to 45 minutes

  5. Number of Pediatric Participants With Problems Understanding Item Wording-Round 2 Interviews

    Based on the results of Round 1 interviews, the four level verbal response scale (Item 1a and Item 2a) of the pediatric versions were selected for further evaluation of ease of use and ease in evaluating remaining doses in Round 2. The second set of interviews were conducted to test if any further revision is required to optimize the items. The items for evaluation in Round 2 included: Item 1 and Item 2 for ease of ELLIPTA use and ease of evaluating remaining doses with a verbal scale of four options (Very easy, Easy, Hard, Very hard) and Item 3 for evaluation of the ability of participants to differentiate between inhalers consisting of three options (Yes, No, The same). The number of pediatric participants with problems understanding item wording has been presented.

    Measured: Up to 45 minutes

  6. Number of Pediatric Participants With Difficulty Providing Responses to Items-Round 2 Interviews

    The items for evaluation in Round 2 included: Item 1 and Item 2 for ease of ELLIPTA use and ease of evaluating remaining doses with a verbal scale of four options (Very easy, Easy, Hard, Very hard) and Item 3 for evaluation of the ability of participants to differentiate between inhalers consisting of three options (Yes, No, The same). The number of pediatric participants with difficulty in providing response to items has been presented.

    Measured: Up to 45 minutes

  7. Number of Pediatric Participants With Difficulty in Distinguishing Between the Responses to Items-Round 2 Interviews

    The items for evaluation in Round 2 included: Item 1 and Item 2 for ease of ELLIPTA use and ease of evaluating remaining doses with a verbal scale of four options (Very easy, Easy, Hard, Very hard) and Item 3 for evaluation of the ability of participants to differentiate between inhalers consisting of three options (Yes, No, The same). The number of pediatric participants who had difficulty in distinguishing between the response to items has been presented.

    Measured: Up to 45 minutes

  8. Number of Caregiver Participants Who Had Difficulty Providing Responses to Caregiver Items-Round 2 Interviews

    Based on the results of Round 1 interviews, both the items of caregiver version were retained for further evaluation in Round 2. The number of caregivers who had difficulty in providing responses to caregiver version of items has been presented below.

    Measured: Up to 45 minutes

  9. Number of Additional Ease of Use Items Identified

    Caregivers were asked if there were any concepts regarding ease of use that were missing from the pediatric or caregiver versions according to them. The number of ease of use items as identified by caregiver participants has been presented.

    Measured: Up to 45 minutes

Secondary outcomes (2)
  1. Number of Pediatric Participants Who Were Able to Use ELLIPTA Whistle

    At the end of cognitive debriefing of the items, the interviewers demonstrated how to use the ELLIPTA whistle and then the pediatric participants were provided with a whistle and asked to produce an audible sound. The number of pediatric participants who were able to produce an audible sound using the ELLIPTA whistle has been presented.

    Measured: Up to 45 minutes

  2. Number of Participants With Attempts Required to Produce an Audible Sound

    At the end of cognitive debriefing of the items, the pediatric participants were asked to use the ELLIPTA whistle to produce an audible sound. The number of pediatric participants who required one to two attempts or more than three attempts to produce an audible sound has been presented.

    Measured: Up to 45 minutes
