EU PAS Register NumberEUPAS8391
Official titleReal-world effectiveness of extrafine vesrus standard particle inhaled corticosteroids: A comparative effectiveness analysis of extrafine (EF) hydrofluoroalkane beclometasone (HFA-BDP) and Ciclesonide versus commonly prescribed standard particle inhaled corticosteroids for patients prescribed asthma therapy in The Netherlands.
Study title acronymExtrafine vesrus stand particle ICS effectiveness

Effectiveness evaluation
Primary scope : Effectiveness evaluation
12. Main objective(s)
What is the main objective of the study?
The aim of this study is to compare effectiveness (in terms of asthma control) of EF-ICS and SP-ICS therapies in patients from The Netherlands prescribed asthma therapy .
Are there primary outcomes?Yes
Severe exacerbation:
• Asthma-related hospital admissions AND
• Prescription for acute courses of oral steroids
Risk Domain Asthma Control (RDAC):
• Absence of asthma-related hospital admissions OR
• Absence of prescription for acute oral steroids
Overall Asthma Control:
• Achieved RDAC AND
• Average daily dose of ≤200mcg salbutamol / ≤500mcg terbutaline
Are there secondary outcomes?Yes
Treatment stability:
• Achieved RDAC
• Addition of new therapy, including LTRA, THEO or LABA OR
• ICS dose increase by ≥50%
• Change ICS type and/or device (sensitivity definition only)
Average daily SABA dose prescribed in the year following ICS therapy initiation, calculated as [(Count of inhalers * doses per inhalers / 365) * mcg strength]
13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Not applicable/no follow-up
15. Data analysis plan
Please provide a brief summary of the analysis method
Patients will be matched on key baseline characteristics (t-test/chi square test, p<0.05). Residual confounders will be adjusted for in the statistical model (multivariate analyses, p<0.05).
Initial ICS doses (FP-equivalents) will be compared through conditional logistic regression (p<0.05). Primary and secondary outcomes will be compared over the outcome period through conditional logistic regression (CLR) models.
Results are expressed as Rate Ratio (RR)/ Odds Ratio (OR) with 95% confidence intervals (CI).
