Efficacy and safety of empagliflozin in combination with insulin in Chinese patients with type 2 diabetes and insufficient glycaemic control: A phase III, randomized, double‐blind, placebo‐controlled, parallel study.

Aim: To evaluate the efficacy and safety of empagliflozin in combination with insulin ± oral antidiabetic drugs (OADs) over 24 weeks, in Chinese patients with type 2 diabetes (T2D) who had insufficient glycaemic control. Materials and Methods: This was a randomized, double‐blind, placebo‐controlled, parallel group, multicentre phase III study. Adult patients with T2D and insufficient glycaemic control who received insulin ± up to two OADs were randomized (1:1:1) to receive empagliflozin 10 or 25 mg, or placebo for 24 weeks. The primary endpoint was change from baseline in HbA1c at week 24. Results: Of 219 randomized patients, 73 patients were in each treatment group; baseline characteristics were comparable among the groups. There was a significantly larger decrease from baseline in HbA1c (adjusted mean treatment difference −0.99 and −0.98 for in the empagliflozin 10 and 25 mg groups, respectively; P <.0001) with both doses of empagliflozin than with placebo. There were also significantly larger decreases from baseline in fasting plasma glucose, 2‐hour postprandial glucose and body weight with both empagliflozin doses than with placebo. Among patients in the empagliflozin 10 mg, 25 mg and placebo groups, 17.8%, 9.6% and 11.0% reported confirmed hypoglycaemic events, respectively (nominal P =.2422 and.7661 in the empagliflozin 10 and 25 mg groups, respectively), and no Clinical Events Committee‐confirmed diabetic ketoacidosis events were reported. Conclusions: In Chinese patients with T2D, empagliflozin combined with insulin ± OADs improved glycaemic control and was well tolerated, without an increased risk of hypoglycaemia.
