Improving Asthma Control in the Real World: A Systematic Approach to Improving Dulera Adherence
  • Phase

    Phase 4
  • Study Type

    Interventional
  • Study Participants

    50
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

Drug Dulera

Dulera is a combination product containing a corticosteroid and a long-acting beta2-adrenergic agonist, FDA approved and indicated for treatment of asthma in patients 12 years of age and older.

  • Other names: mometasone furoate/formoterol fumarate dihydrate

All Events

Asthma Control

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.

Adherence to Dulera 100/5 and 200/5

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.
