#117 - BATURA Trial: Does a Combo Inhaler Help Mild Asthma?

There have been countless advances in controller therapies for asthma, but our go-to rescue inhaler, a quick-relief bronchodilator, hasn’t changed in decades.

In this episode of The Itch Review, we spotlight “As-Needed Albuterol–Budesonide in Mild Asthma” published in The New England Journal of Medicine, May 19, 2025. This article looks at the BATURA trial, which tested whether adding budesonide to albuterol rescue inhalers cuts exacerbations in adults whose mild asthma remains uncontrolled on occasional albuterol/short-acting beta agonist (SABA) therapy.

Could this combo inhaler really cut severe asthma attacks in people with mild disease?

What we cover in our episode about the BATURA trial:

Understanding asthma: In asthma, your airways both tighten up and get swollen. Treating both the tightness and the swelling right when you feel symptoms could stop a full-blown attack.
All-online trial: BATURA used telehealth to enroll 2,516 people with mild asthma from across the U.S. and ran the study until it saw a preset number of 172 serious attacks.
Big takeaways: The combo inhaler cut serious attacks by almost half, halved yearly flare-ups, and slashed steroid use by 63%. All without people needing to use their medication more often.
Why it ended early: An independent safety board reviewed the data mid-trial and concluded that the combo inhaler was so clearly better that it would’ve been unfair to continue giving anyone the old treatment.
What’s next: We still need studies on teens and children to ensure that these same benefits hold true for younger patients.
