A Clinical Study to Evaluate the Effect of the Connected Inhaler System (CIS) on Adherence to Maintenance Therapy in Poorly Controlled Asthmatic Subjects

GlaxoSmithKline (GSK) in collaboration with Propeller Health has developed a sensor, which can clip on to the ELLIPTA® dry powder inhaler (DPI) and monitor the time and date that the ELLIPTA DPI cover is fully opened and closed. Additionally, a sensor will be attached to the rescue medication metered dose inhaler (MDI). The data from both sensors will be fed back to the subject via an application (app) on smart phone and will be reviewed by the subject's health care professional (HCP) via an online dashboard. The sensors, app, dashboard and systems to provide data comprise the CIS. This study will be the first to evaluate the effect of CIS on adherence to maintenance therapy in subjects with uncontrolled asthma. This is an open-label, randomized, parallel group study in asthmatic subjects currently on a fixed dose inhaled corticosteroid (ICS)/long-acting beta 2 agonist (LABA) maintenance therapy. Eligible subjects will receive RELVAR®/BREO® maintenance therapy via ELLIPTA DPI and salbutamol rescue medication via MDI with sensors attached to both inhalers during the run-in period, which may last for up to 3 months. Eligible subjects will then be randomized into five treatment arms depending on whether the data, from RELVAR/BREO ELLIPTA or RELVAR/BREO ELLIPTA and salbutamol MDI, is fed back to the subject or subject and HCP, or not at all. The treatment period for the study is approximately 6 months and there will be a follow-up period one week post last visit. The total duration of a subject in the study will be approximately 9 months. RELVAR, BREO and ELLIPTA are registered trademarks of GlaxoSmithKline group of companies.

Primary outcomes

  1. Percentage of ELLIPTA Doses Taken (Daily Adherence) Between Month 4 and Month 6 as Determined by the Maintenance Sensor for Arms; ("Cohort 1: Data on Maintenance Use Supplied to Participant and HCP" and"Cohort 5: no Data Supplied to Participant or HCP")

    Time frame: Month 4 to Month 6

    Daily adherence is defined as the participant taking one dose of Relvar/Breo ELLIPTA, within a 24-hour period, starting at 12.00 anti-meridiem (a.m.) each day of the treatment period. The percentage of ELLIPTA doses taken were determined by the clip-on sensor attached to ELLIPTA, which records the time and date when the ELLIPTA cover was opened and closed. Analysis was carried out by Analysis of Covariance (ANCOVA) model. Least Square mean percentage of ELLIPTA doses taken (daily adherence) between Months 4 and 6 was determined by the maintenance sensor daily adherence over the last three months of the study period (between months 4 to 6). The daily adherence to ELLIPTA maintenance therapy when both the participant and the HCP were supplied with data from the maintenance sensor (Cohort 1) versus no data supplied to the participant or HCP (Cohort 5) is summarized.

  6. Change From Baseline in Asthma Control Test (ACT) Total Score

    Time frame: Baseline and Month 6

    The ACT is a validated self-completed questionnaire utilizing 5 questions to assess asthma control on a 5-point categorical scale ranging from 1 (not controlled at all) to 5 (completely controlled). Total score is calculated as the sum of the scores from the 5 questions and can range from 5 to 25, with higher scores indicating better control. An ACT total score of 5 to 19 suggests that the participant's asthma is unlikely to be well controlled, whilst a score of 20 to 25 suggests that the participant's asthma is likely to be well controlled. Baseline value was the latest assessment prior to randomization (Day 1, pre-dose). Change from Baseline was calculated as post-dose visit value minus the Baseline value.

  7. Percentage of Participants Attaining Asthma Control (Percentage of Participants With an ACT Total Score >=20) at Month 6

    Time frame: Month 6

    Percentage of participants attaining asthma control was defined as participants with an ACT total score >=20 at Month 6. The ACT is a validated self-completed questionnaire utilizing 5 questions to assess asthma control on a 5-point categorical scale ranging from 1 (not controlled at all) to 5 (completely controlled). Total score is calculated as the sum of the scores from the 5 questions and can range from 5 to 25, with higher scores indicating better control. An ACT total score of 5 to 19 suggests that the participant's asthma is unlikely to be well controlled, whilst a score of 20 to 25 suggests that the participant's asthma is likely to be well controlled. Percentage of participants who attained asthma control at Month 6 is presented.

  8. Percentage of Participants With an Increase From Baseline >=3 in ACT Total Score at Month 6

    Time frame: Baseline and Month 6

    The ACT is a validated self-completed questionnaire utilizing 5 questions to assess asthma control on a 5-point categorical scale ranging from 1 (not controlled at all) to 5 (completely controlled). Total score is calculated as the sum of the scores from the 5 questions and can range from 5 to 25, with higher scores indicating better control. An ACT total score of 5 to 19 suggests that the participant's asthma is unlikely to be well controlled, whilst a score of 20 to 25 suggests that the participant's asthma is likely to be well controlled. Baseline value was the latest assessment prior to randomization (Day 1, pre-dose). Percentage of participants with an increase from Baseline >=3 in ACT total score at Month 6 is presented.

  9. Percentage of Participants Who Have Either an ACT Total Score of >=20 and/or an Increase From Baseline >=3 in ACT Total Score at Month 6

    Time frame: Baseline and Month 6

    The ACT is a validated self-completed questionnaire utilizing 5 questions to assess asthma control on a 5-point categorical scale ranging from 1 (not controlled at all) to 5 (completely controlled).
