Characteristics of Empagliflozin Initiators

Completed

Conditions: Type 2 Diabetes

Interventions: Drug: Empagliflozin
Drug: Other SGLT2 inhibitors
Drug: Other non-insulin GLDs

Registration Number: NCT03050619

Lead Sponsor: Boehringer Ingelheim

Brief Summary: Empagliflozin, a sodium glucose cotransporter 2 (SGLT-2) inhibitor, was launched in the United Kingdom (UK) in August 2014. It can be expected that patients initiating empagliflozin may differ in their characteristics from patients initiating other glucose lowering drugs (GLDs) that have been on the market longer (e.g. patients may have poorer glucose control). Therefore, the proposed study aims to characterize patients with T2DM in the UK initiating empagliflozin in terms of baseline characteristics, concomitant medications, and comorbidities compared to patients with type 2 diabetes mellitus (T2DM) initiating other SGLT-2 inhibitors or other non-insulin GLDs. Due to the mode of action, some patients taking empagliflozin have experienced weight loss in clinical trials. A theoretical possibility exists that empagliflozin may be used by patients without T2DM. Therefore, this study also aims to assess the potential off-label use of empagliflozin compared to other non-insulin GLDs.

Extent of Off-label Use	Baseline	To assess off-label use the number of study participants without a recorded diagnosis of T2DM was calculated for each exposure category (people with other types of diabetes, people without diabetes, people younger than 18 years old, and women during pregnancy and breastfeeding). For the assessment of drug use during the pregnancy and breastfeeding period, the look-back period was 270 days (9 months) before and including the index date. To assess the use in pediatric population, the study participants were stratified by age into adults (≥18 years of age) and pediatrics (\<18 years of age).
