1. Study identification
EU PAS Register NumberEUPAS13818
Official titleA 5-year multi-center, observational post-authorization safety study to document the drug utilisation of Wakix® in the treatment of narcolepsy with or without cataplexy and to collect information on its long termthe safety of Wakix® when used in routine medical practice
Study title acronymWAKIX PASS
Study typeObservational study
Brief description of the studyInternational, multi-center, non-interventional, prospective, open-label long-term post-authorization safety study (PASS) on the use of Wakix (pitolisant) a new H3R antagonist approved for the treatment of narcolepsy with or without cataplexy in adults. The patients will be observed during routine clinical practice. Study is planned to follow up patients for five years or to the end of the study. The product (Wakix)will be prescribed and used based on the routine clinical practice as well as on the individual situation of each patient and according to the approved SPC.
The main objectives are to collect information on the long term safety of pitolisant Wakix® (all reported adverse events) when used in a real-life setting, and to monitor and document the drug utilization patterns of Wakix® in routine medical practice.
The other objectives are to assess the clinical benefit of a treatment with pitolisant (Wakix®) in a real-life setting on excessive diurne somnolence and other symptoms of narcolespy, and the health care resource use (hospitalizations, emergency visits, unscheduled visits) due to narcolepsy, to measure the treatment compliance, the quality of life and disease burden.
Patients will be recruited in the 4 countries where Wakix will be first launched (i.e. France, UK, Italy, Germany), by around 8 to 10 sites in each.

Risk assessment
Drug utilisation study
Primary scope : Risk assessment
12. Main objective(s)
What is the main objective of the study?
To collect information on the long term safety of pitolisant Wakix® (all reported adverse events) when used in a real-life setting.
Are there primary outcomes?Yes
Adverse events reported by the investigators will be coded using the MedDRA (preferred term) and assessed in terms of seriousness, severity, causality, recovery. Safety results will be described in accordance with GVP Module VI.
Are there secondary outcomes?Yes
ESS, CGI, BDI, BMI, NSAQ, 8-item Morisky, FOSQ-10, EQ5D, hospitalization, emergency visit, work day loss
and drug utilization pattern : patient characteristics, medical history, co-medications, Wakix® dosage changes, Wakix® interruption and reason, co-medication changes, drop out.

What is the design of the study?
Drug utilisation study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Patients will be followed for Five years or until premature stop of Wakix
15. Data analysis plan
Please provide a brief summary of the analysis method
Quantitative variables will be described using the following descriptive statistics: sample size, number of missing values, mean, standard deviation, median, minimum and maximum. Qualitative variables will be described using the following descriptive statistics: sample size, number of missing values, and percentage of each modality calculated on the responses expressed. The bivariate statistical analyses performed will undergo statistical tests, based on the nature of the variables analyzed:
For qualitative variables, the Chi2 test will be applied, apart from the theoretical sample sizes are less than 5; in this case, Yates continuity correction or Fisher's exact test will be used. For quantitative variables, when distribution is close to normal (non-significant Shapiro-Wilk test), a Student's t-test or analysis of variance will be performed. If this is not the case, non-parametric tests will be used (Wilcoxon, Kruskal-Wallis).
