Can an injected biologic cut steroid Flare-Ups in a Tough-to-Treat asthma complication?
NCT ID NCT07828327
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers are studying depemokimab, an injected biologic drug, in adults aged 18 to 75 who have allergic bronchopulmonary aspergillosis (ABPA) along with severe eosinophilic asthma. The study tracks how many asthma attacks need systemic steroids and whether participants' quality of life changes over the course of treatment. Everyone in this small, open-label study receives depemokimab, and there is no comparison group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- depemokimab, an injected biologic drug
- What this could lead to
- If it helps, depemokimab could offer people with ABPA and severe eosinophilic asthma fewer steroid-requiring flare-ups and better day-to-day breathing.
- What could go wrong
- This is a small, open-label study of 10 people with no comparison group, so results may not hold up in larger trials. Depemokimab is an injection and can cause reactions at the injection site or allergic reactions.

Inclusion Criteria: * Female and Male patients aged 18-75 years inclusively at the time of Visit 1 with a physician diagnosis of Allergic Bronchopulmonary Aspergillosis has met the ISHAM Working Group Diagnostic Criteria for ABPA:Predisposing condition: Bronchial asthma Obligatory criteria (both should be present)Type I aspergillus skin test positive (immediate cutaneous hypersensitivity Aspergillus antigen) or elevated IgE level against Aspergillus fumigatus (Af) Aspergillus niger or Aspergillus flavus may be eligible provided antigen-specific IgE and IgG measurements are available for use. Elevated total IgE levels (\>1,000IU/mL)\* Other criteria (at least two of three)Presence of precipitating or IgG antibodies against Af in serum Radiographic pulmonary opacities consistent with ABPA Total eosinophil count \>500 cells/uL in steroid naïve patients (may be historical)(if the patient meets all other criteria, an IgE value \<1,000 IU/mL may be acceptable) Severe chronic asthma (for at least 12 months) requiring treatment with high dose ICS plus asthma controller prior to Visit 1Other acceptable asthma controllers include long acting bronchodilators (e.g. a long acting beta-agonist (LABA) or long-acting muscarinic antagonists (LAMA)), a leukotriene inhibitor, theophylline preparations and/or maintenance OCS (daily or every other day OCS requirement in order to maintain asthma control Documented current treatment with high daily doses of ICS ( \>500ug of FP equivalent) plus at least one other asthma controller for at least 3 months prior to Visit 1For ICS/LABA combination preparation, highest-strength maintenance doses approved in the U.S. will meet this criterion If the ICS and the other asthma controller therapies are given by separate inhalers, then the patient must be on a high daily ICS dose for 3 months prior to entering the study. History of at least 2 asthma exacerbations while on ICS plus another asthma controller (see inclusion criterion 2 for examples) that required treatment with systemic corticosteroids (IM, IV, or oral) in the 12 months prior to Visit 1. For patients receiving oral corticosteroids as a maintenance therapy, an exacerbation is defined as a temporary increase of their maintenance dose for a minimum of 3 days. Weight \> 40kg Exclusion Criteria: * Clinically important pulmonary disease other than asthma with allergic bronchopulmonary aspergillosis (i.e., chronic obstructive pulmonary disease (COPD), cystic fibrosis, sarcoidosis, and pulmonary fibrosis).History of anaphylaxis to any biologic therapy.Known history of allergy or hypersensitivity reaction to Depemokimab or any of its components.Currently pregnant, breastfeeding, or lactating women.Concurrent enrollment in another interventional or post-authorization safety study, unless it is observational.
