- Non-adherent patients to inhaled treatment (ICS + LABA).
- Active smokers or former smokers exceeding 20 packs year.
- Exacerbation at inclusion visit M0.
- Active malignancy or malignancy in remission over less than 5 years.
- Active parasitic infection or parasitic infection in the past 24 weeks.
- Hypersensitivity to Benralizumab or to any of the excipients of Fasenra® (histidine, histidine hydrochloride monohydrate, trehalose dihydrate, polysorbate 20)
- Patients requiring other immunosuppressive and immunomodulator drugs
- Patients requiring other biotherapy than Benralizumab, with or without French's marketing authorisation in severe asthma
- Patients requiring other biotherapy than Benralizumab that affects the immune system
- SARS-COV2 infection
- Pregnancy, lactation, or patients with childbearing potential refusing efficient contraceptive method.
- Patients under psychiatric condition altering their comprehension and their ability to give informed consent.

What is the study measuring?
Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Predictive value of early blood gene expression signature of Benralizumab
Time Frame: 12 months
|
To establish the predictive value of early blood gene expression signature of Benralizumab response associated with a significant reduction of the number of exacerbations in treated severe asthmatic patients.
We will evaluate an early blood gene expression signature of Benralizumab response through a clinically relevant reduction of the number of exacerbations at month 12 (M12).

12 months

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Molecular signature predictive of stabilization
Time Frame: 12 months
|
To establish at M0 (baseline) a molecular signature predictive of stabilization in severe asthmatic patients treated by Benralizumab.
At M0 a composite blood molecular signature predictive of reduction of the exacerbation rate at M12 in severe asthmatic patients treated by Benralizumab will be assessed.
The definition of stable class of patients (low category) is used as a target for the prediction.
The methods used for the primary objective are applied to secondary objective using similar input data on a different 3-class prediction target.
|
12 months
|
The stability of the signature over time
Time Frame: 0 month, 3 months, 6 months and 9 months
|
To evaluate the stability of the signature over time (from early at M0, M3, to late prediction at M6 and M9) considering patient trajectories.
The significance of center and the relevance of time dependent modelling will be evaluated using generalised mixed models on independently established molecular response signature.
It is expected a robust and reproducible gene expression to assess the inter and intra-individual trajectories of the signature over time and across centers (from early at M0 and M3, to late prediction at M6 and M9).
|
0 month, 3 months, 6 months and 9 months
|
The association of gene expression patterns
Time Frame: 12 months
|
To evaluate the association of gene expression patterns with both objective and subjective improvement.
Correlations network between blood gene expression of Benralizumab significant response will be assessed thanks to weighted gene correlation network analysis (gene co-expression network analysis (WGCNA)) with an expected increase in forced expiratory volume at one second (FEV1) + Asthma Quality of Life Questionnaire (AQLQ) + peak-flow values and expected decrease of Asthma Control Questionnaire-7 items (ACQ-7), -6 items (ACQ-6) scores.
|
12 months
|
Association of gene expression patterns and clinical characteristics
Time Frame: 0 months
|
To evaluate association of gene expression patterns at M0 (baseline) and clinical characteristics of frequent exacerbations.
Correlations network between blood gene expression at M0 and clinical characteristics of frequent exacerbations will be assessed thanks to WGCNA.
|
0 months
|
Stratification value of gene expression in severe asthma
Time Frame: 12 months
|
To assess the stratification value of gene expression in severe asthma and its correlation with clinical subgroups and clinically meaningful variables such as number of exacerbations.
Correlation network between stratification value of gene expressions in severe asthma and its correlation with clinical subgroups will be assessed thanks to WGCNA.
This analysis is based on pairwise correlations between genetic variables and clinical variables underlying the amount of overall variance captured by high dimensional gene expression datasets.
|
12 months
|
Scenario-based cost-utility analysis
Time Frame: 12 months
|
To conduct a scenario-based cost-utility analysis.Concerning cost-utility analysis, two strategies of treatment with Benralizumab will be compared: the first one will consider a strategy not using an early blood gene expression signature of Benralizumab response and the second will consider a simulated strategy using an early blood gene expression signature of Benralizumab response.
