Brief Summary:
A randomized clinical study to assess the impact of Symbicort® pMDI medication reminders on adherence in COPD patients

Condition or disease Intervention/treatment Phase
Chronic Obstructive Pulmonary Disease (COPD Device: Arm 1: BreatheMate device with application Device: Arm 2: BreatheMate device without application Phase 4

Detailed Description:
Chronic obstructive pulmonary disease (COPD) is a common disease with substantial associated morbidity and mortality. COPD is the third leading cause of death in the US and claimed 133,965 US lives in 2009. In 2011 12.7 million US adults were estimated to have COPD. However, approximately 24 million US adults have evidence of impaired lung function, indicating an under diagnosis of COPD. COPD also has a potentially harmful economic impact. In 2010, COPD resulted in over 10 million office visits, nearly 1.5 million emergency department visits, 700,000 hospitalizations, and 133,575 deaths in the US. In 2010, US total medical treatment costs attributed solely to COPD (i.e., excluding comorbidities) were estimated to be $32.1 billion with an additional $3.9 billion in COPD costs resulting from worker absenteeism. Even in industrialized countries such as the US, where anti-smoking initiatives have been relatively successful, the legacy of past smoking behavior in aging populations ensures that the COPD burden will unavoidably continue to climb over the next 20 to 30 years. Adherence rates for inhaled combination therapy is poor (average 3.9 refills per year). COPD patients with lower adherence tend to have higher overall healthcare costs, as demonstrated in a 24 month study of 33,816 patients in the US, which found: Patients continuing therapy had lower costs of care by $3764 compared with patients who had ceased to take their maintenance therapy. COPD patients with higher adherence to prescribed regimens experienced fewer hospitalizations and lower Medicare costs (-$2185) than those who exhibited lower adherence behaviors. Given the poor adherence with inhaled combination therapy seen in patients with COPD, and associated morbidity/mortality and economic costs, the present study is being conducted to see if medication reminders can be used to improve adherence in this population.

Arm Intervention/treatment
Active Comparator: BreatheMate device and application
BreatheMate Bluetooth device that attaches to Symbicort pressurized Metered Dose Inhaler (pMDI) and cell phone with application that sends medication and refill reminders and reminders to complete a COPD questionnaire
Device: Arm 1: BreatheMate device with application
The service known as 'BreatheMate' is a patient support tool that monitors daily Symbicort inhaler use. The BreatheMate service includes a bluetooth monitoring device that is attached to subjects' Symbicort pMDI inhaler which automatically detects and logs their maintenance medication use. Subjects will receive audio-visual daily reminders (beeps and flashes) on the BreatheMate Bluetooth device. The bluetooth device transmits this data to a cellular phone that is provided to all subjects in the study. Subjects in the intervention group will also receive audio-visual alerts (beeps, flashes) from the bluetooth device to take their medication.

Placebo Comparator: BreatheMate device without application
BreatheMate Bluetooth device that attaches to Symbicort pressurized Metered Dose Inhaler (pMDI) and cell phone without any reminders or alerts.
Device: Arm 2: BreatheMate device without application

The service known as 'BreatheMate' is a patient support tool that monitors daily Symbicort inhaler use. The BreatheMate service includes a bluetooth monitoring device that is attached to subjects' Symbicort pMDI inhaler which automatically detects and logs their maintenance medication use. The functionality of audio-visual daily reminders (beeps and flashes) is deactivated for this control group.

The BreatheMate service also includes a cellular phone that will display whether the Bluetooth monitoring device is paired and communicating with the cellular phone. The Bluetooth device will transmit data regarding medication usage to the cellular phone.





Primary Outcome Measures :
  1. Mean Number of Adherent Sets of Symbicort Puffs Per Day Over the 26-Week Study Period [ Time Frame: From baseline to end of treatment (EOT), (6 months). ]
    The mean number of adherent sets of Symbicort puffs per day for each group, over an average of 26 weeks was calculated. An adherent set of puffs was defined as exactly 2 sets of 2 Symbicort puffs per day. The 2 puffs that constitute a set must have been taken within 60 minutes of each other. A mean of 2.00 sets would be equal to 100% adherence (2 sets of 2 puffs). Subjects who did not take exactly 2 sets of 2 puffs on any given day throughout their device time on study were considered non-adherent for that day.


Secondary Outcome Measures :
  1. Mean Clinical COPD Questionnaire (CCQ) Scores at Baseline, EOT, and Mean Change in Score Over the 26-Week Study Period. [ Time Frame: From baseline to EOT (6 months). ]
    The CCQ is a 10-item measure of a subject's COPD symptoms, divided into 3 domains (Symptoms: Items 1, 2, 5 and 6; Functional State: Items 7, 8, 9, and 10; and Mental State: Items 3 and 4). Individual items within the CCQ were equally weighted. The total score was calculated by adding the scores of the 10 items and dividing that number by 10 (=number of items). In addition, individual domain scores were calculated. The total CCQ score and each of the 3 domain scores range from 0 (very good health status) to 6 (extremely poor health status). CCQ data was collected for all subjects at baseline and EOT visits. The mean CCQ total and domain scores at both baseline and 26 weeks (EOT) are presented along with the mean change from baseline at EOT or week 26. A positive change indicates worsening symptoms and a higher value is indicative of a poorer health status.

  2. Mean Total and Domain Weekly CCQ Scores Over Each 2-Month Study Interval for the Intervention Group. [ Time Frame: From baseline to EOT (6 months). ]
    The CCQ is a 10-item measure of a subject's COPD symptoms, divided into 3 domains (Symptoms: Items 1, 2, 5 and 6; Functional State: Items 7, 8, 9, and 10; and Mental State: Items 3 and 4). Individual items within the CCQ were equally weighted. The total score was calculated by adding the scores of the 10 items and dividing that number by 10 (=number of items). Individual domain scores were also calculated. The total CCQ score and each of the 3 domain scores range from 0 (very good health status) to 6 (extremely poor health status). Subjects in the intervention group took the CCQ weekly throughout the study. The 26-week treatment period was broken down into 3, 2-month intervals: Interval 1: from study day 1 to study day 63 (inclusive), Interval 2: study day 64 to study day 126 (inclusive), Interval 3: study day 127 to EOT (inclusive). The last week of each 2-month interval was used to represent that interval and results are presented for the total CCQ score and the 3 domain scores.

  3. Mean Number of Adherent Sets of Puffs Per Day for Each 2-Month Study Interval. [ Time Frame: From baseline to EOT (6 months). ]
    The mean number of adherent sets of Symbicort puffs per day was calculated for each subject, for each of the 3, 2-month study intervals. Interval 1: from study day 1 to study day 63 (inclusive); Interval 2: study day 64 to study day 126 (inclusive); Interval 3: study day 127 to EOT (inclusive). A set is 2 puffs taken on the same calendar day, with the 2 puffs taken within 60 minutes of each other. The mean number of sets of Symbicort puffs per day was determined only for the days during device time on study for each subject.

  4. Mean Number of Adherent Days Over the 26-Week Study Period. [ Time Frame: From baseline to EOT (6 months). ]
    The total number of adherent days was defined as the number of treatment days a subject took 2 sets of 2 puffs of Symbicort and the inhalations in a puff set were within 60 minutes of each other. Subjects who did not take exactly 2 sets of 2 puffs on any given day throughout their device time on study were considered non-adherent for that day. The total number of adherent days for each subject was counted over the 26 week treatment period and the mean number of adherent days per group is presented.

  5. Mean Number of Symbicort Prescription Refills at Pharmacy Over the 26-Week Study Period. [ Time Frame: From baseline to EOT (6 months). ]
    The total number of Symbicort prescriptions filled at a pharmacy during the 26-week treatment period was counted per subject. The mean number of Symbicort 30-day prescription refills per subject was then calculated and presented per group.
