EU PAS Register NumberEUPAS9827
Official titleDrug utilisation study (DUS) on the use of Cholib® (fenofibrate and simvastatin fixed combination): a European multinational study using secondary health records databases
Study title acronym
Study typeObservational study
Brief description of the studyStatins have been shown to reduce total cholesterol and LDL-C levels. They are commonly used and recommended in patients with dyslipidaemia (Catapano et al. 2011).3 Fibrates are also used to lower total cholesterol and triglycerides (TG) levels. They are prescribed to patients intolerant to statins alone, or as second line of treatment in combination with statins.
Combination of simvastatin and fenofibrate leads to additional improvement of lipid parameters compared with simvastatin monotherapy in patients with mixed dyslipidaemia who required a treatment targeting a broader lipoprotein spectrum (Grundy et al. 2005).11
Cholib® is a fixed combination tablet, composed of fenofibrate (145 mg) and simvastatin (20mg or 40mg). It will be the first available registered drug combining both substances in one tablet.
Cholib® is indicated as adjunctive therapy to diet and exercise in high cardiovascular risk adult patients with mixed dyslipidaemia to reduce triglycerides and increase HDL- C levels when LDL-C levels are adequately controlled with the corresponding dose of simvastatin monotherapy.
Initiation of Cholib® treatment requires an adequate pre-treatement with simvastatin (at 20 or 40 mg) otherwise it is considered off-label use. This potential risk is part of the Risk Management Plan (RMP) and will be further investigated in this study conducted to estimate the proportion of patients who initiated Cholib® without prior simvastatin therapy.

9. Number of subjects
Estimated total number of subjects323
Additional information
Without evidence on the real percentage of off-label use of Cholib, an assumption of 30% is used. It is based on the study of Radley et al. on the percentage of off-label use of 160 community prescribed drugs using a database of 150 million patients, which showed mean off-label use of 21%. For a confidence interval of 95% and a margin of error of 5%, 323 patients per country would be needed.

15. Data analysis plan
Please provide a brief summary of the analysis method
The statistical analysis will be conducted using SAS® software Version 9.3 for Windows ™ (SAS Institute, North Carolina, USA) and Excel.
The statistical unit is the patient. Calculations will be performed on raw data without extrapolation.
Continuous variables will be described by the number of valid cases, the number of missing values, mean, standard deviation, median, quartiles (Q1, Q3) and range.
Categorical variables will be described as the total number and relative percentage per category.
The number of missing data will be indicated; they will not be replaced and not be taken into account for the calculation of the percentages.
Confidence intervals of 95% will be calculated for each item, when relevant.
Prescribers’ profile will be described per country: age, gender, specialty and region through LTD database.
Summaries will be reported at country level. For each analysis period (pre- and post- launch periods) they will be categorized according to the speciality.
