What is the purpose of this trial?

This trial tests a new inhaler approach for people with asthma who often forget or struggle to use their inhalers regularly. It focuses on individuals diagnosed with mild or moderate persistent asthma who have not adhered to their prescribed inhaler routine, resulting in partly controlled or moderately uncontrolled symptoms. Participants will either use an as-needed inhaled treatment (Budesonide/Formoterol, an ICS/LABA therapy) or continue their usual inhaler routine. Those with asthma for at least six months, a history of not refilling inhalers as expected, and partly controlled symptoms might be suitable candidates. Participants need a smartphone and must be willing to use a device that tracks inhaler use. As a Phase 1, Phase 2 trial, this research aims to understand how the treatment works in people and measure its effectiveness in an initial, smaller group.

Do I need to stop my current medications for this trial?

The trial does not specify if you need to stop your current medications. However, you must be on maintenance ICS treatment and as-needed SABA for at least 6 months before joining. You cannot be using a biologic medication or investigational treatment for asthma.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that combining budesonide and formoterol is generally safe for people with mild asthma. Studies have not identified any new safety issues when these medications are used together. In fact, using budesonide-formoterol as needed reduces the risk of asthma attacks compared to budesonide alone. Patients experienced fewer severe asthma episodes with this inhaler method. While all medications can have side effects, evidence suggests that budesonide-formoterol is a safe choice for managing asthma symptoms. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about the new approach of using budesonide/formoterol for asthma because, unlike the standard routine of daily maintenance inhalers, this treatment offers a symptom-driven strategy. Most treatments involve regular dosing of inhaled corticosteroids (ICS) combined with as-needed short-acting beta-agonists (SABA). In contrast, budesonide/formoterol allows for on-demand use, combining an inhaled corticosteroid with a long-acting beta-agonist (LABA). This could improve adherence and provide more immediate relief, potentially making asthma management more flexible and effective for patients.

What evidence suggests that this trial's treatments could be effective for asthma?

Research shows that Budesonide/Formoterol, which participants in this trial may receive as part of the symptom-driven ICS/LABA treatment strategy, effectively manages asthma. Studies have found that this treatment reduces asthma attacks and improves lung function. For example, one study found that patients using Budesonide/Formoterol had fewer asthma attacks compared to those using albuterol. Another study showed that this treatment reduced severe asthma attacks when used as both a regular and emergency inhaler. Overall, the evidence supports its effectiveness in controlling asthma symptoms and reducing hospital visits. ^{5 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for people aged 12-75 with mild or moderate persistent asthma who have been prescribed maintenance inhalers and as-needed SABA but are not using their inhalers regularly. They must own a smartphone, have missed at least two ICS refills in the past six months, and have partially controlled to moderately uncontrolled asthma.

Inclusion Criteria

You are between 12 and 75 years old when you join the study.

You have been diagnosed with mild or moderate persistent asthma and have been using certain medications for at least 6 months.

Able to understand and provide informed consent.

Exclusion Criteria

You have certain lung diseases like chronic obstructive pulmonary disease (COPD), cystic fibrosis, or alpha 1 anti-trypsin deficiency.

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.

Patients who do not complete at least 70% of the twice-daily texts during the two weeks after screening.

In a 24-week study involving 111 asthma patients, the use of a combination inhaler containing both an inhaled corticosteroid (ICS) and a long-acting beta-agonist (LABA) did not significantly improve adherence to medication compared to using separate inhalers.

Adherence rates were similar across both groups, with mean adherence at 82.4% for the combination inhaler, indicating that combining medications into one inhaler may not be as effective in improving adherence as previously thought.
