Diabetes Res Clin Pract 2024; 213:111752. [PMID: 38908549 DOI: 10.1016/j.diabres.2024.111752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 06/10/2024] [Accepted: 06/17/2024] [Indexed: 06/24/2024]
Abstract
OBJECTIVE To examine the real-world effects of imeglimin on glycemic control and other metabolic factors in patients with type 2 diabetes (T2DM). METHODS A retrospective longitudinal study was conducted based on a chart review. We recruited patients with T2DM who took imeglimin continuously for at least 3 months. Data on various metabolic parameters were collected at the first prescription of imeglimin and at 3, 6 and 12 months after the initiation of imeglimin. Statistical comparisons were performed using paired t-tests. RESULTS 68 patients were eligible for this study. HbA1c decreased by 0.7 % at 3 months, 1.1 % at 6 months and 1.0 % by 12 months after the initiation of imeglimin. The decreases in HbA1c were observed regardless of age, gender, body mass index, duration of diabetes, renal function and concomitant use of hypoglycemic agents. There were also significant decreases in body weight, low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C) and non-HDL-C during imeglimin treatment. CONCLUSIONS This is the first report showing the long-term effects of imeglimin in a real-world setting. We confirmed the glucose-lowering effects of imeglimin. Furthermore, favorable effects of imeglimin on body weight and serum lipids were also suggested.

Abstract
PURPOSE OF REVIEW This review aims to collect all the data regarding imeglimin and present it as one of the options for managing diabetes. RECENT FINDINGS It is a new drug that has recently been approved as an oral anti-diabetic drug, either as monotherapy or in combination with other oral antidiabetic drugs including insulin, with modest HbA1c reduction, and a fairly safe profile. Imeglimin was first approved in 2021 in Japan and China and is available in India from October 2022. Imeglimin is the first compound in a new class of oral anti-diabetic medications known as "glimins" that include a tetrahydrotriazine ring. Glimins act by amplifying glucose-stimulated insulin secretion (GSIS) and preserving β-cell mass, leading to augmented insulin secretion. Furthermore, It also intensifies insulin action by inhibiting of hepatic glucose output and recovery of altered insulin signalling in both hepatocytes (liver) and myocytes (skeletal muscle). This is a unique mode of action than has been demonstrated to be distinct from other classes of drugs, as it targets both insulin secretion and insulin resistance by correcting the mitochondrial dysfunction. Imeglimin has been studied in various phase III trials which have equivocally shown it to be effective in lowering glucose levels and improving pancreatic function and its recommended dose set at 1000 mg bid.

Abstract
Diabetes is a rapidly growing health challenge and epidemic in many developing countries, including India. India, being the diabetes capital of the world, has the dubious dual distinction of being the leading nations for both undernutrition and overnutrition. Diabetes prevalence has increased in both rural and urban areas, affected the younger population and increased the risk of complications and economic burden. These alarming statistics ring an alarm bell to achieve glycemic targets in the affected population in order to decrease diabetes-related morbidity and mortality. In the recent years, diabetes pathophysiology has been extended from an ominous triad through octet and dirty dozen etc. There is a new scope to target multiple pathways at the molecular level to achieve a better glycemic target and further prevent micro- and macrovascular complications. Mitochondrial dysfunction has a pivotal role in both β-cell failure and insulin resistance. Hence, targeting this molecular pathway may help with both insulin secretion and peripheral tissue sensitization to insulin. Imeglimin is the latest addition to our anti-diabetic armamentarium. As imeglimin targets, this root cause of defective energy metabolism and insulin resistance makes it a new add-on therapy in different diabetic regimes to achieve the proper glycemic targets. Its good tolerability and efficacy profiles in recent studies shows a new ray of hope in the journey to curtail diabetes-related morbidity.

Development of Imeglimin Electrospun Nanofibers as a Potential Buccal Antidiabetic Therapeutic Approach. Pharmaceutics 2023; 15:pharmaceutics15041208.

Abstract
The prevalence of type 2 diabetes (T2D) has been growing worldwide; hence, safe and effective antidiabetics are critically warranted. Recently, imeglimin, a novel tetrahydrotriazene compound, has been approved for use in T2D patients in Japan. It has shown promising glucose-lowering properties by improving pancreatic beta-cell function and peripheral insulin sensitivity. Nevertheless, it has several drawbacks, including suboptimal oral absorption and gastrointestinal (GI) discomfort. Therefore, this study aimed to fabricate a novel formulation of imeglimin loaded into electrospun nanofibers to be delivered through the buccal cavity to overcome the current GI-related adverse events and to provide a convenient route of administration. The fabricated nanofibers were characterized for diameter, drug-loading (DL), disintegration, and drug release profiles. The data demonstrated that the imeglimin nanofibers had a diameter of 361 ± 54 nm and DL of 23.5 ± 0.2 μg/mg of fibers. The X-ray diffraction (XRD) data confirmed the solid dispersion of imeglimin, favoring drug solubility, and release with improved bioavailability. The rate of drug-loaded nanofibers disintegration was recorded at 2 ± 1 s, indicating the rapid disintegration ability of this dosage form and its suitability for buccal delivery, with a complete drug release after 30 min. The findings of this study suggest that the developed imeglimin nanofibers have the potential to be given via the buccal route, thereby achieving optimal therapeutic outcomes and improving patient compliance.

Improving the Effects of Imeglimin on Endothelial Function: A Prospective, Single-Center, Observational Study. Diabetes Ther 2023; 14:569-579. [PMID: 36732433 PMCID: PMC9981829 DOI: 10.1007/s13300-023-01370-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Accepted: 01/12/2023] [Indexed: 02/04/2023] Open
Abstract
INTRODUCTION Endothelial dysfunction is a risk factor for cardiovascular disease in patients with diabetes. We hypothesized that imeglimin, a novel oral hypoglycemic agent, would improve endothelial function. METHODS In this study, imeglimin was administered to patients with type 2 diabetes and HbA1c ≥ 6.5% who were not receiving insulin therapy. A meal tolerance test (592 kcal, glucose 75.0 g, fat 28.5 g) was performed before and 3 months after administration, and endothelial function, blood glucose, insulin, glucagon, and triglycerides were evaluated. Endothelial function was assessed by flow-mediated dilation (FMD). RESULTS Twelve patients (50% male) with a median age of 55.5 years old (interquartile range [IQR] 51.3-66.0) were enrolled. Fasting FMD did not differ before or 3 months after imeglimin administration (from 6.1 [3.9-8.5] to 6.6 [3.9-9.0], p = 0.092), but 2 h postprandial FMD was significantly improved 3 months after imeglimin administration (from 2.3 [1.9-3.4] to 2.9 [2.4-4.7], p = 0.013). In terms of the glucose profile, imeglimin administration significantly improved HbA1c (from 7.2 ± 0.6% to 6.9 ± 0.6%, p = 0.007), fasting glucose (from 138 ± 19 mg/dL to 128 ± 20 mg/dL, p = 0.020), and 2 h postprandial glucose (from 251 ± 47 mg/dL to 215 ± 68 mg/dL, p = 0.035). The change in 2 h postprandial FMD between before and 3 months after imeglimin administration (Δ2 h postprandial FMD) was negatively correlated with Δ2 h postprandial glucose (r = - 0.653, p = 0.021) in a univariate correlation coefficient analysis. Both patients with and without decreased postprandial glucose 3 months after imeglimin administration had improved postprandial FMD. CONCLUSION In this small study, imeglimin administration improved 2 h postprandial FMD. Both glycemic control-dependent and -independent mechanisms might contribute to improved endothelial function.
