Improving Asthma Control in the Real World: A Systematic Approach to Improving Dulera Adherence
Lead SponsorAsthma Management Systems
StatusCompleted Results Posted
40 subjects with moderate-to-severe asthma will be randomly selected for study in which 20, will be monitored for medication use (Dulera 100/5, Dulera 200/5 and Proventil HFA) over 3 months. These intervention subjects will receive medication use feedback at each visit, while the control group will receive the standard of asthma care. Those interventional subjects with Dulera adherence<60% will receive feedback based on an asthma adherence disease management model protocol, Asthma Adherence Pathway. Intervention clinicians will been trained in Motivational Interviewing to reduce subject ambivalence about medication use. The primary hypothesis is that subjects who receive medication monitoring and Motivational Interviewing adherence strategies will have better asthma control, as measured by the Asthma Control Questionnaire, than the control group.
Primary Clinical Hypothesis: Poorly controlled subjects with moderate-to-severe asthma (measured by Asthma Control Questionnaire (ACQ) ≥ 1) despite treatment with Dulera, who are treated with the asthma adherence disease management protocol, Asthma Adherence Pathway™, will achieve greater asthma control than similar control subjects who are treated with the current standard of care.
Primary end point: There will be four measures of Asthma Control Questionnaire (ACQ) over time over 3 months. The primary endpoint is the third month measure of ACQ.
Secondary Clinical Hypothesis: The asthma adherence disease management program, Asthma Adherence Pathway™, will increase observed adherence to Dulera relative to a benchmark of 60% adherence (i.e., expected prescribed actuations).
Secondary end points: a) Average adherence to Dulera over the three month study period
Tertiary Clinical Hypothesis: Responses to Adult Asthma Adherence Questionnaire (AAAQ) will be related to Dulera Adherence
Tertiary Study Endpoints: There will be 2 measures of the AAAQ (first and last visit) and the tertiary endpoint is the last visit
Inclusion Criteria: Physician diagnosis of asthma of moderate severity Subjects ≥ 18 years of age Currently receiving an inhaled corticosteroid medication and being prescribed Dulera 100/5 as part of standard of care based upon asthma severity and dosing guidelines Asthma Control Questionnaire (ACQ) result > 1.0 at entry Demonstration of correct inhalation technique for use of meter-dosed inhalers (MDIs) History of reversible airway obstruction documented by treating physician Exclusion Criteria: intermittent asthma; emphysema, chronic obstructive pulmonary disease; chronic bronchitis; cystic fibrosis; medication that may have a drug interaction with Dulera Exclusion Criteria Intermittent asthma (asthma exacerbations or symptoms < 3 days/week) Diagnosis of emphysema in prior year Diagnosis at any time of: chronic obstructive pulmonary disease (COPD), chronic bronchitis, cystic fibrosis, bronchiectasis, Churg Strauss, Wegener's, sarcoidosis, pulmonary hypertension or lung cancer On any medication documented to have a drug interaction with Dulera

Asthma Control Questionnaire measured at each office visit. ACQ integrates values by 6 clinical questions related to symptoms and the value related to FEV1% predicted with a total score ranging from 0-6 and higher values indicating poorer asthma control.
Subjects in the monitoring group will have adherence greater than or equal to the 60% benchmark Adherence was calculated by taking the number of doses actually taken divided by the number of doses prescribed and multiplying by 100.
Subjects in the monitoring group will have adherence greater than or equal to the 60% benchmark Overall interval value was the mean of daily percent
