Aim
To evaluate henagliflozin, a novel sodium‐glucose co‐transporter‐2 inhibitor, as monotherapy in patients with type 2 diabetes and inadequate glycaemic control with diet and exercise.
Materials and Methods
This multicentre trial included a 24‐week, randomized, double‐blind, placebo‐controlled period, followed by a 28‐week extension period. Four hundred and sixty‐eight patients with an HbA1c of 7.0%–10.5% were randomly assigned (1:1:1) to receive once‐daily placebo, or 5 or 10 mg henagliflozin. After 24 weeks, patients on placebo were switched to 5 or 10 mg henagliflozin, and patients on henagliflozin maintained the initial therapy. The primary endpoint was the change in HbA1c from baseline after 24 weeks.
Results
At Week 24, the placebo‐adjusted least squares (LS) mean changes from baseline in HbA1c were −0.91% (95% CI: −1.11% to −0.72%; P < .001) and −0.94% (−1.13% to −0.75%; P < .001) with henagliflozin 5 and 10 mg, respectively; the placebo‐adjusted LS mean changes were −1.3 (−1.8 to −0.9) and −1.5 (−2.0 to −1.1) kg in body weight, and −5.1 (−7.2 to −3.0) and −4.4 (−6.5 to −2.3) mmHg in systolic blood pressure (all P < .05). The trends of these improvements were sustained for an additional 28 weeks. Adverse events occurred in 81.0%, 78.9% and 78.9% of patients in the placebo, henagliflozin 5 and 10 mg groups, respectively. No diabetic ketoacidosis or major episodes of hypoglycaemia occurred.
Conclusions
Henagliflozin 5 mg and 10 mg as monotherapy provided effective glycaemic control, reduced body weight and blood pressure, and was generally well tolerated.
