Asthma treatment showdown: higher dose or triple therapy?
NCT ID NCT05919394
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study aimed to compare two treatment options for adults with T2-high asthma that remains uncontrolled despite medium-dose inhaled steroids and long-acting beta agonists. One group would receive a higher dose of the same combination, while the other would add a third medication (a long-acting muscarinic antagonist). The goal was to see which strategy led to better asthma control after one year. However, the study was withdrawn before any participants were enrolled.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- inhaled corticosteroid and long-acting beta agonist (ICS/LABA) with or without a long-acting muscarinic antagonist (LAMA)
- What this could lead to
- If completed, this could help identify the best treatment step for people with T2-high asthma that is not well controlled.
- What could go wrong
- The study was withdrawn before enrolling anyone, so no results are available. It was a real-world study, not a tightly controlled trial, which can make findings less certain.

Inclusion Criteria: * Patients between 18 and 80 years of age diagnosed of uncontrolled asthma. * T2 high asthma: \> 300 cels/mm3 blood Eos (current value) or 150 cels/mm3 blood Eos (current value) and a historical value ≥ 300 cels/mm3 or FENO ≥ 25 ppb (current value). * Uncontrolled asthma, this is, ACT \<20 and/or \> 1 of an exacerbation in the last 12 months, despite treatment with ICS/LABA at medium dose. * Written informed consent. Exclusion Criteria: * Patients who refuse to sign the informed consent form. * Medical situation that prevents the collection of study information. * Diagnosis of severe uncontrolled asthma established with criteria other than those established (ACT \<20 and/or \> 1 exacerbation in the last 12 months, despite treatment with ICS / LABA at medium dose). * Medical or administrative situation that prevents the patient from following up to a minimum of 52 weeks. * Treatment with high dose ICS/LABA, LAMA, systemic corticosteroid, azithromycin, monoclonal antibody.
