Introduction:
The aim of this randomized, double-blind, parallel-group study was to investigate the safety and efficacy of empagliflozin monotherapy for 52 weeks in Japanese patients with type 2 diabetes (T2DM).
Methods:
In a 12-week dose-finding period, patients [N = 547; mean baseline glycosylated hemoglobin (HbA1c) 7.92-8.02%] received empagliflozin (5, 10, 25, or 50 mg) or placebo. In a 40-week extension period, patients on empagliflozin 10 or 25 mg continued the same treatment and patients on other doses were reallocated to empagliflozin 10 or 25 mg. Outcomes at week 52 included changes from baseline in HbA1c, fasting plasma glucose (FPG), weight and blood pressure (BP) in patients who received empagliflozin 10 or 25 mg in both the initial 12 weeks and the extension and safety in patients treated with ≥1 dose of empagliflozin 10 or 25 mg.
Results:
Adjusted mean ± SE changes in HbA1c from baseline at week 52 were -0.67 ± 0.09% and -0.86 ± 0.09%, in FPG were -24.7 ± 3.2 mg/dL and -31.3 ± 3.4 mg/dL, and in body weight were -3.1 ± 0.4 kg and -3.1 ± 0.4 kg, with empagliflozin 10 and 25 mg, respectively. Both doses reduced systolic and diastolic BP. Adverse events were reported in 70.8% and 66.8% of patients on empagliflozin 10 and 25 mg, respectively. Confirmed hypoglycemic adverse events (plasma glucose ≤70 mg/dL and/or requiring assistance) were reported in one patient per group.
Conclusion:
Empagliflozin monotherapy for 52 weeks led to sustained reductions in HbA1c, FPG, weight and BP and was well tolerated in Japanese patients with T2DM.
