Efficacy and safety of the sodium-glucose co-transporter-2 inhibitor empagliflozin in elderly Japanese adults (≥65 years) with type 2 diabetes: A randomized, double-blind, placebo-controlled, 52-week clinical trial (EMPA-ELDERLY)
Abstract
AIM: Use of sodium-glucose co-transporter-2 inhibitors (SGLT2is) for glycaemic control is increasing in individuals with type 2 diabetes (T2D) for their additional benefits on heart failure and chronic kidney disease. However, SGLT2is generally reduce body weight, which might promote sarcopenia in older individuals. We evaluated the effects of the SGLT2i empagliflozin on muscle mass and strength in addition to glucose control in elderly adults with T2D.
MATERIALS AND METHODS: Individuals with T2D aged ≥65 years with body mass index ≥22 kg/m2 and glycated haemoglobin (HbA1c) 7.0%-10.0% were randomized 1:1 to once-daily empagliflozin 10 mg or placebo for 52 weeks. The primary endpoint was change from baseline in HbA1c at week 52. Secondary endpoints included changes from baseline in muscle mass and strength.
RESULTS: Of the 129 individuals randomized, 72.4% were men, mean age 74.1 years, body mass index 25.6 kg/m2 and HbA1c 7.6%. The placebo-adjusted mean change from baseline in HbA1c at week 52 with empagliflozin was -0.57% [95% confidence interval (CI) -0.78, -0.36]. Change in body weight was -3.26 kg and -0.90 kg with empagliflozin and placebo, respectively (placebo-adjusted difference: -2.37 kg; 95% CI -3.07, -1.68). Placebo-adjusted change in muscle mass was -0.61 kg (95% CI -1.61, 0.39), fat mass -1.84 kg (95% CI -2.65, -1.04) and grip strength -0.3 kg (95% CI -1.1, 0.5).
CONCLUSIONS: Empagliflozin improved glucose control and reduced body weight without compromising…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 129 participants or records.
