1. Study identification
EU PAS Register NumberEUPAS17678
Official titleAgomelatine Drug Utilisation Study in Selected European Countries: A Multinational, Observational Study to Assess Effectiveness of Risk-Minimisation Measures
Study title acronym
Study typeObservational study
Brief description of the studyNon-interventional, multinational Post-Autorisation Safety Study in patients initiating agomelatine treatment in routine clinical practice in Denmark, France, Germany, and Spain. The study includes a retrospective medical data abstraction to collect patient data before and after the last minimization measures in order to evaluate adherence to the liver test monitoring regimen and compliance with relevant contraindications and a cross-sectional patient survey to assess patients’ reasons for non-compliance with the liver test monitoring regimen.
Medical data abstraction will collect characteristics of agomelatine users including relevant comorbidities, date, dose, and duration of agomelatine prescriptions and of fluvoxamine and/or ciprofloxacin; date of liver function tests (ALT and AST) and results. The patient survey will collect patients’ characteristics, knowledge of the key liver safety information, and reasons for non-compliance with liver test monitoring when applicable.

11. Scope of the study
What is the scope of the study?
Drug utilisation study
Patient survey
Primary scope : Drug utilisation study
12. Main objective(s)
What is the main objective of the study?
To evaluate the effectiveness of additional risk minimisation measures for agomelatine before and after implementation of these measures. For the medical record abstraction: to evaluate the adherence to the liver test monitoring regimen and the compliance with relevant contraindications. For the patient survey: to evaluate patients’ reasons for non-compliance with the liver test monitoring regimen
Are there primary outcomes?Yes
For the medical record abstraction: proportion of patients with a liver test performed before treatment or at initiation and at least one test performed during treatment
For the survey: Proportion of patients acknowledging receipt of the patient booklet and reason for non-compliance to the liver test monitoring regimen
Are there secondary outcomes?Yes
For the medical record abstraction : proportion of patients with a liver test performed before treatment or at initiation and a test performed at 3, 6, 12, and 24 weeks after treatment initiation—accounting for “duration of treatment” and dose escalation
13. Study design
What is the design of the study?
Cross-sectional study
Drug utilisation 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
Descriptive analyses overall and by country, and, if numbers allow, by specialty.
Medical record abstraction: A single estimate of the prevalence of adherence to liver test will be provided separately for each study period with 95% CIs around the point estimate. The difference between the prevalence of adherence before and after RMMs will be calculated as an estimate of the change with the 95% CI. A chi-square test or a t-test will be used to test the differences between the two study periods (before and after RMM).
Patient survey: The proportion of patients acknowledging receipt of the patient booklet and the reasons for non-compliance to the liver test monitoring will be provided
The number of subjects with missing data will be reported for each variable. Descriptive analysis comparing patients with and without missing data will be conducted. To assess the potential impact of a non-random missing data pattern for adherence/compliance, a sensitivity analysis will be conducted.
