Imeglimin is the first in class tetrahydrotriazine‐containing oral glucose-lowering agent that has been studied in clinical trials as a possible monotherapy or add-on therapy to lower fasting plasma glucose. It is being developed as an alternative and a complement to drugs that act on insulin‐resistant organs or drugs acting on insulin secretion and β‐cell protection. When investigated in preclinical studies, Imeglimin showed that it can target insulin‐resistant organs by decreasing excessive hepatic glucose production and increasing muscle glucose uptake. It also showed a potential to restore appropriate glucose‐stimulated insulin secretion and protect β‐cells from cell death under high glucose conditions. Imeglimin acts on the liver, muscle, and the pancreas (6), three key organs involved in the pathophysiology of type 2 diabetes through suspected mechanisms targeting the mitochondria and reduced oxidative stress. Imeglimin decreases hepatic glucose production and increases muscle glucose uptake. Recently, Imeglimin demonstrated increased insulin secretion in response to glucose in diabetic patients during a hyperglycemic clamp study. In clinical trials, Imeglimin treatment for 7 days raised the insulin secretory response to glucose, improved β-cell glucose sensitivity and tended to decrease hepatic insulin extraction. Imeglimin did not affect glucagon secretion.
