Summary

The goal of this trial test two known effective asthma strategies. Treatment guidelines recommend combination therapy of inhaled corticosteroids (ICS) with a long-acting beta-agonist (LABA) inhaled medications. This strategy is known as MART (maintenance and reliever therapy). The second strategy is PARTICS (patient activated reliever triggered ICS) strategy instructs patients to use an ICS metered dose inhaler (ICS) each time they use their rescue inhaler. In addition, they are instructed to take 5 puffs of the ICS after each rescue nebulizer use. PARTICS has been shown to reduce exacerbations, increase asthma control and quality of life, however, the question remains if PARTICS is as effective as MART and therefore be an alternative to MART. This trial will test PARTICS and MART head-to-head. The trial will include adults with moderate-to-severe asthma at risk for an asthma exacerbation, currently using a combination ICS. The main questions aim to answer: * Is PARTICS as effective as SMART? * Might PARTICS be more effective than SMART? Is the relative effectiveness of PARTICS versus SMART affected by frequent nebulizer use for asthma relief? * Do PARTICS and SMART diverge in terms of their effectiveness on differing asthma outcomes important to patients? * Do socioeconomic factors affect the relative effectiveness of PARTICS and SMART? Researchers will compare non frequent nebulizer (NFN) users - less than once a week to frequent nebulizer users - once a week or more, to assess whether the PARTICS strategy is ono-inferior (or superior to the MART strategy in reducing exacerbations, (primary outcome), increasing asthma control and quality of life and decrease days lost from work/school or usual activities. Most participants will be consented, enrolled, and randomized virtually, others will be consented, enrolled and randomized in person. Once randomized they will be instructed on how to use the prescribed medication: * Participants randomized to MART will be instructed to use the prescribed ICS/LABA for maintenance and as needed for rescue. * Participants randomized to PARTICS will be instructed to use the prescribed ICS each time they use their rescue inhaler and take 5 puffs of the newly prescribed ICS after each rescue nebulizer use. * Participants will be followed for 16 months by monthly survey.

Detailed description

Asthma affects 25 million people in the USA with a disproportionate effect on African American/Black (AA/B) and Hispanic/Latinx (H/L) patients. Inhaled corticosteroids are the backbone of asthma therapy. A so-called SMART (Single Maintenance And Reliever Therapy) approach to ICS therapy has been recommended by US and international guidelines for patients with moderate to severe asthma, because it has been shown in multiple studies to reduce asthma exacerbations. However, these studies have been explanatory, with narrow entry criteria, have only been performed ex- US (with a formulation not available in the US), and have not included significant numbers of AA/B and H/L patients. Further, there are significant barriers to implementation which include those related to patient patterns of concomitant medication use and beliefs. In a PCORI-funded pragmatic study in 1200 AA/B and H/L patients with asthma, designed with patient partners, we studied an alternative approach we call PARTICS (Patient Activated Reliever Triggered ICS). We reported, in this study published in the New England Journal of Medicine in 2022, that we not only reduced asthma exacerbations, we also improved other outcomes important to patients including asthma control, quality of life and days lost from school, work or usual activities. Our patient advisors have published on their positive experience and other advisors have collaborated with us to publish 9 additional papers which include such topics as an exploration of how socioeconomic factors affect asthma outcomes and how to simply identify patients at risk for asthma exacerbations, among additional topics. Both SMART and PARTICS have advantages and drawbacks. As seen in letters of support from the heads of the US and international guidelines for asthma treatment committees, the lack of direct comparison between the two represents a major gap in knowledge required to formulate best-care practice recommendations. Specifically, it is unclear as to what degree one approach can substitute for the other and whether they differentially affect distinct domains of asthma outcomes. In collaboration with our advisors, we therefore propose iCARE (Improving the Quality of Care for Asthma patients at Risk of Exacerbations), a large pragmatic study to directly compare SMART to PARTICS in diverse populations and across multiple domains. The study results, regardless of outcome, will help guide the approach to patient-centered asthma care.
