The efficacy and safety of imeglimin as add-on therapy in patientswith type 2 diabetes inadequately controlled with metformin monotherapy


OBJECTIVE A 12-week study assessed the efficacy and safety of a new oral antidiabetic agent, imeglimin, as add-on therapy in type 2 diabetes patients inadequately controlled with metformin alone. RESEARCH DESIGN AND METHODS A total of 156 patients were randomized 1:1 to receive imeglimin (1,500 mg twice a day) or placebo added to a stable dose of metformin (1,500–2,000 mg/day). Change in A1C from baseline was the primary efficacy outcome; secondary outcomes included fasting plasma glucose (FPG) and proinsulin/insulin ratio. RESULTS After 12 weeks, the placebo-subtracted decrease in A1C with metformin-imeglimin was −0.44% (P < 0.001). Metformin-imeglimin also significantly improved FPG and the proinsulin/insulin ratio from baseline (−0.91 mg/dL and −7.5, respectively) compared with metformin-placebo (0.36 mg/dL and 11.81). Metformin-imeglimin therapy was generally well-tolerated with a comparable safety profile to metformin-placebo. CONCLUSIONS Addition of imeglimin to metformin improved glycemic control and offers potential as a new treatment for type 2 diabetes. Imeglimin is the first in a new tetrahydrotriazine-containing class of oral antidiabetic agents, the glimins. Imeglimin decreases hepatic glucose production, increases muscle glucose uptake, and improves pancreatic glucose-dependent insulin secretion (1). Previous studies have demonstrated imeglimin to be as effective as metformin in improving glycemia (2). Since metformin is the preferred first-line therapy for type 2 diabetes, the current study examined the efficacy, safety, and tolerability of imeglimin in combination with metformin in patients with type 2 diabetes inadequately controlled with metformin alone.
