1. Study identification
EU PAS Register NumberEUPAS13413
Official titlePost-authorisation safety study in patients with type 2 diabetes mellitus to assess the risk of acute liver injury, acute kidney injury and chronic kidney disease, severe complications of urinary tract infection, genital infections, and diabetic ketoacidosis among patients treated with empagliflozin compared to patients treated with DPP-4 inhibitors
Study title acronymPASS renal, liver injury, infection, ketoacidosis
Study typeObservational study
Brief description of the studyEmpagliflozin (Jardiance), a highly potent and selective inhibitor of the sodium-glucose cotransporter 2 (SGLT2), was approved in Europe in May 2014 for the treatment of type 2 diabetes mellitus (T2DM) to improve glycaemic control in adults. As part of the risk management plan, Boehringer Ingelheim International GmbH (BI) has committed to conduct a post-authorisation safety study (PASS) to evaluate the liver and renal safety of empagliflozin. The study will also evaluate the risks of severe complications of urinary tract infections (UTIs), genital infections and diabetic ketoacidosis. To evaluate the association between empagliflozin use and mentioned outcomes routinely collected health information from the Clinical Practice Research Datalink (CPRD), in the United Kingdom. For the evaluation of the rarest outcomes, the Danish Population Registries in Denmark and the HealthCore Integrated Research Database (HIRD) in the United States. This PASS will be conducted through an observational cohort study among adult patients with T2DM and at least 12 months of continuous enrolment in the data source where new users of empagliflozin will be compared to new users of dipeptidyl peptidase-4 (DPP4) inhibitors. Estimations will be made on the crude and adjusted incidence rates and adjusted incidence rate ratios of the primary and secondary outcomes. The primary outcomes will be: acute liver injury (ALI) in patients without predisposing conditions, acute kidney injury, severe complications of urinary tract infection, genital infections, and diabetic ketoacidosis. The secondary outcomes will be: ALI in patients with or without predisposing conditions, chronic kidney disease, and severe genital infections.

9. Number of subjects
Estimated total number of subjects151184
Additional information
The number of empagliflozin new users and crude incidence rates of the events of interest was assessed annually. Based on data from the second and third interim, the number of expected empagliflozin users by the end of the study period was projected to be insufficient. The addition of data sources and the extension of the study period should allow to reach the target number of users.

14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Follow-up will start the day after the date of the first prescription for study drugs, and end at the date of the: outcome event, death, study end, transfer out or end of registration in the practice, specific exclusion criteria are met, 120 days after the end date of the first continuous treatment of the study drugs, or the date in which a new treatment episode with other study drug starts.
15. Data analysis plan
Please provide a brief summary of the analysis method
The following estimates and comparisons will be generated:
Crude and adjusted incidence rates of each of the outcomes among empagliflozin new users and DPP-4 inhibitor new users. Incidence rates will be reported as point estimates (in cases per 1,000 person-years) and 95% confidence intervals (CIs).
Summary IRRs, after adjusting for propensity score deciles, among empagliflozin new users vs. DPP-4 inhibitor new users.
The adjusted IRRs for each of the primary outcomes will be the main effect estimates of interest. Adjusted incidence rates and IRRs will be calculated using analytic techniques involving stratification by categories of propensity scores. An additional analysis will further stratify the IRRs by categories of insulin use at the index date. Sensitivity analyses will be performed to evaluate the potential for other sources of bias and confounding.
Meta-analytic methods will be used to combine the IRRs obtained from the main analysis performed by all the data sources.
