Aims/Introduction: As the pathophysiology of type 2 diabetes (T2DM) differs in East Asian patients compared with that in other ethnic groups, a comprehensive evaluation of the safety of empagliflozin (EMPA) in East Asian patients is desirable to inform clinical practice in the patient population. We therefore investigated the safety and tolerability of EMPA in East Asian patients with T2DM.

Materials and Methods: Data were pooled from patients with T2DM treated with placebo, EMPA 10 mg or 25 mg in 15 Phase I-III trials plus 4 extension studies. Adverse events (AEs) were analyzed in the subgroup of patients from East Asian countries. (China, Hong Kong, Japan, Korea, Taiwan) (N=2141).

Results: Total exposure was 953, 1072, and 1033 patient-years in the placebo, EMPA 10 mg, and 25 mg groups, respectively. The incidence of any AEs, severe AEs, serious AEs, and AEs leading to discontinuation was no higher in patients who were treated with either dose of EMPA than in those treated with placebo. The incidence of hypoglycemia differed according to glucose-lowering medications used at baseline. Events consistent with urinary tract infection occurred less frequently with EMPA than placebo (5.3-5.8 vs. 7.2/100 patient-years). Events consistent with genital infection occurred more frequently with EMPA than placebo (1.5-1.7 vs. 0.2/100 patient-years). The incidence of AEs consistent with volume depletion was similar across treatment groups (0.8-1.4/100 patient-years). Rates of bone fractures, renal AEs, venous thromboembolic events, hepatic injury, lower limb amputation and diabetic ketoacidosis were similar or no higher with EMPA vs. placebo.

Conclusions: In this pooled analysis, EMPA was well tolerated in the East Asian patients with T2DM based on &gt;3,000 patient-years’ exposure, consistent with results from the overall analysis population. The result was in line with package inserts in East Asian countries and did not raise new safety concerns.
