1. Study identification
EU PAS Register NumberEUPAS13199
Official titleObservational single-cohort data base study of dapagliflozin utilisation in Europe
Study title acronymNA
Study typeObservational study
Brief description of the studyThis drug utilization study is set up to describe the characteristics of European patients newly prescribed dapagliflozin by age, sex, dapagliflozin dose, country, selected co-morbidities, and selected concomitant medications.
It will specifically describe dapagliflozin use in:
• patients > 75 years-old,
• combination use with loop diuretics or pioglitazone,
• patients with a known history of moderate or severe renal impairment and in kidney failure,
• patients lacking a diagnostic code indicating type 2 diabetes.
This is an observational single-cohort data base study with descriptive data analyses among patients receiving dapagliflozin within electronic medical records in Europe. The study will describe the utilization pattern of dapagliflozin during the first 3.5 years after marketing authorization and launch in Europe, specifically in Belgium, France, Germany, Italy, Spain and United Kingdom.
Will be included in the study all patients identified in the database(s) who newly received at least one dapagliflozin prescription during the study period.
Data will be collected from IMS Health Longitudinal Patient Databases (LPDs) which come directly from physicians’ EMR.
A patient will be identified as newly exposed when he/she has at least one dapagliflozin prescription recorded in the study database(s).
Outcomes include: Patient demographics: age, sex, country, Baseline history of type 2 diabetes, Baseline history of moderate or severe renal impairment, Concomitant medications at baseline and during dapagliflozin use.
Follow-up will begin on the date a patient is first prescribed dapagliflozin, and it will continue until the end of study or discontinuation of dapagliflozin.
In this study descriptive analyses of the data will be conducted.

12. Main objective(s)
What is the main objective of the study?
The main objective of the study is to describe the characteristics of patients newly prescribed dapagliflozin by age, sex, dapagliflozin dose, country, co-morbidities, and concomitant medications in all new users and the following subgroups: patients > 75 years-old, with combination use with loop diuretics or pioglitazone, with a history of renal impairment and patients not reported to have T2DM.
Are there primary outcomes?No
Are there secondary outcomes?No
13. Study design
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
The follow-up period will be used to identify concomitant use of dapagliflozin with loop diuretics or pioglitazone. Follow-up will begin on the date a patient is prescribed dapagliflozin, which will represent the beginning of follow-up (i.e., “index date”). Follow-up will continue until the discontinuation of dapagliflozin.
15. Data analysis plan
Please provide a brief summary of the analysis method
Descriptive statistics will be calculated to describe baseline characteristics among dapagliflozin initiators. These characteristics include age group, sex, initial dapagliflozin dose, country, BMI, eGFR, co-morbidities, concomitant medications, and available results of laboratory testing. We will also describe dapagliflozin use within and outside the labeled indication of type 2 diabetes.
Qualitative variables will be described by frequencies and percentages. For each class, number of missing values will be presented. Quantitative variables will be described with number of observed data, mean, standard deviation, median, first and third quartiles, and number of missing values.
In order to assess the impact of missing data, key variables (e.g. BMI and eGRF) will be checked by describing patients with and without missing values, respectively, regarding basic characteristics available for all or most patients, including age, gender, country, co-medication and co-morbidity.
