QCT Analysis in Search of Predictive Biomarkers for Biologic Treatment in Severe Asthma 

Biologics therapies provide targeted injectable treatment for severe asthma, and are designed to block specific immune pathways that drive airway inflammation. However, its clinical responses remain highly heterogeneous. This variability suggests that severe asthma is developed not only by inflammation but by progressive lung structural remodeling over time.

To investigate this further, CHU Montpellier is using AI-driven quantitative CT analysis to characterize the lung structural changes such as airway dimensions, mucus plugs and trapped air throughout the course of biologic therapy.

Project highlights

  • BENRALISCAN (NCT03976310) is one of the first studies to investigate structural airway evolvement during biologic treatment, following 59 patients with severe eosinophilic asthma
  • First results to be presented at ATS 2026 international conference

Contribution by Thirona

LungQ AI-enabled quantitative image analysis contributes to the research by measuring bronchial widening (Bout/A and Bin/A) and wall thickening (Bwt/A and Bwa/Boa) using LungQ® BA, calculating mucus plug count and volumes using LungQ® MP, and assessing trapped air (low-attenuation region) using LungQ® VERA.   

Detecting subtle yet clinically meaningful structural changes, the AI-powered analysis offer significantly higher precision and reproducibility, enabling exploration of how biologic therapies influence airway structure.
