Symptom-driven ICS/LABA Therapy for Adolescent Patients With Asthma Non-adherent to Daily Maintenance Inhalers

Inclusion Criteria: Able to understand and provide informed consent. Age 18-75 at the time of study enrollment. Provider diagnosed mild or moderate persistent asthma and prescribed maintenance ICS treatment and as needed SABA for at least 6 months prior to enrollment. Suboptimal adherence to prescribed maintenance ICS therapy defined as missing at least expected 2 ICS refills in the prior 6 months based on examination of pharmacy records or a Medication Adherence Report Scale for Asthma (MARS-A) score <4.5. An Asthma Control Test (ACT) score at enrollment greater than or equal to 12 but less than or equal to 20 indicating partially controlled or moderately uncontrolled asthma. iPhone or Android smartphone with an active data plan and willingness to use the Adherium device. Exclusion Criteria: Relevant comorbid pulmonary diseases including, but not limited to a diagnosis of chronic obstructive pulmonary disease (COPD), cystic fibrosis, or alpha 1 anti-trypsin deficiency. Current use of a biologic medication or investigational treatment for asthma. History of asthma requiring ICU admission in the last year. Unwillingness to use or pay for an inhaler that is compatible with the Adherium sensor (fluticasone propionate or budesonide/formoterol). Of note, fluticasone and budesonide/formoterol are formulary tier 1-2 for Missouri Medicaid and most commercial insurances and are believed to be equally or less expensive as alternative inhalers for most patients. Any clinically significant abnormalities on physical exam, laboratory testing, or baseline diagnostic testing that the study team believes will make the study unsafe. Patients who do not complete at least 70% of the twice-daily texts during the two weeks after screening.
