Blood Exosomal Multi-omics and Lung Radiomics for Predicting Efficacy and Prognosis of Severe Eosinophilic ACOS With Biologics (ACOS)
Blood Exosomal Multi-omics and Lung Radiomics for Predicting Efficacy and Prognosis of Severe Eosinophilic ACOS (Asthma-COPD Overlap Syndrome) Treated With Different Biologics: A Real-World Observational Study
연구 개요
상태
상세 설명
Firstly, eligible patients (age ≥14 years, diagnosis of severe eosinophilic ACOS, blood eosinophils ≥150/μL within 3 months or ≥300/μL within 1 year, and clinician decision to start a biologic) will be enrolled. Exclusion criteria include concurrent trial participation, allergy to biologics, malignancy, or prior biologic use.
Then, patients are followed for 48 weeks after the first biologic dose. Visits occur at weeks 0, 1, 2, 4, 8, 16, 24, 40, and 48. Data collected include demographics, medical history, ACQ-6, MiniAQLQ, pre-BD FEV1, exacerbations, medication use, adverse events, and blood routine tests (residual samples for exosome analysis). HRCT and Xe129MRI are optional.
Next, the primary outcome is the composite endpoint of efficacy and prognosis at week 48, defined as: no ACOS exacerbation, no oral corticosteroids, pre-BD FEV1 improvement ≥100 mL from baseline, and ACQ-6 score <1.5 (or ≤0.75). Secondary outcomes include changes in ACQ-6, FEV1, annualized exacerbation rate, MiniAQLQ, OCS dose reduction, and blood exosomal multi-omics and lung radiomics biomarkers.
Finally, statistical analyses include descriptive statistics, paired t-test/Wilcoxon, ANOVA/Kruskal-Wallis, mixed-effects model for repeated measures (MMRM), differential expression analysis (DESeq2/limma), pathway enrichment, machine learning (LASSO, random forest), ROC curves, logistic regression, and Cox regression. A total of 500 patients will be enrolled from multiple centers in China.

Composite efficacy and prognosis endpoint at week 48 in severe eosinophilic ACOS
기간: 48 weeks after the first dose of biologic
|
We define the composite endpoint as achieving ALL of the following at week 48: (1) no ACOS exacerbation (worsening of respiratory symptoms requiring systemic corticosteroids ≥3 days, emergency visit <24h, or hospitalization ≥24h); (2) no use of oral corticosteroids (OCS); (3) pre-bronchodilator FEV1 improvement ≥100 mL from baseline; (4) ACQ-6 score <1.5 (or ≤0.75).
The proportion of patients meeting all four criteria will be calculated.

Change in Asthma Control Questionnaire-6 (ACQ-6) score
기간: Baseline to 48 weeks
|
ACQ-6 is a validated questionnaire (6 items, score 0-6, lower = better control).
Change from baseline will be assessed at weeks 1,2,4,8,16,24,40,48.
Mean difference and standard deviation will be reported.
|
Baseline to 48 weeks
|
|
Change in pre-bronchodilator FEV1 (mL)
기간: Baseline to 48 weeks
|
FEV1 (forced expiratory volume in 1 second) will be measured using spirometry according to international standards (ATS/ERS).
Change in mL from baseline will be calculated at weeks 8, 16, and 48.
|
Baseline to 48 weeks

|
Annualized rate of ACOS exacerbations
기간: 48 weeks
|
Number of ACOS exacerbations per year during the 48-week follow-up.
Exacerbation defined as worsening of respiratory symptoms requiring systemic corticosteroids (≥3 days), emergency department visit (<24 hours), or hospitalization (≥24 hours).
Rate = (total exacerbations × 365.25) / follow-up days.

48 weeks
|
|
Change in Mini Asthma Quality of Life Questionnaire (MiniAQLQ) score
기간: Baseline to 48 weeks
|
MiniAQLQ is a 15-item questionnaire (score 1-7, higher = better quality of life).
Change from baseline will be assessed at weeks 8, 16, 24, and 48.

|
Change in blood exosomal multi-omics biomarkers
기간: Baseline to 48 weeks
|
Residual blood from routine tests (2-3 mL per time point at weeks 0,4,8,16,24,40,48) will be used to isolate exosomes.
Transcriptomics (RNA-seq), proteomics (mass spectrometry), and metabolomics (LC-MS) profiles will be compared between baseline and week 48.
Differentially expressed features (|log2FC|>1, FDR<0.05) will be reported.

Change in lung radiomics features
기간: Baseline to 48 weeks
|
For patients who undergo HRCT or Xe129MRI (optional), radiomics features (e.g., texture, shape, intensity) will be extracted using standard software.
Changes from baseline to week 24 and 48 will be analyzed.
