Li Y, Lou N, Liu X, Zhuang X, Chen S. Exploring new mechanisms of Imeglimin in diabetes treatment: Amelioration of mitochondrial dysfunction. Biomed Pharmacother 2024; 175:116755. [PMID: 38772155 DOI: 10.1016/j.biopha.2024.116755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 04/26/2024] [Accepted: 05/13/2024] [Indexed: 05/23/2024] Open
Abstract
With the increasing prevalence of type 2 diabetes mellitus (T2DM), it has become critical to identify effective treatment strategies. In recent years, the novel oral hypoglycaemic drug Imeglimin has attracted much attention in the field of diabetes treatment. The mechanisms of its therapeutic action are complex and are not yet fully understood by current research. Current evidence suggests that pancreatic β-cells, liver, and skeletal muscle are the main organs in which Imeglimin lowers blood glucose levels and that it acts mainly by targeting mitochondrial function, thereby inhibiting hepatic gluconeogenesis, enhancing insulin sensitivity, promoting pancreatic β-cell function, and regulating energy metabolism. There is growing evidence that the drug also has a potentially volatile role in the treatment of diabetic complications, including metabolic cardiomyopathy, diabetic vasculopathy, and diabetic neuroinflammation. According to available clinical studies, its efficacy and safety profile are more evident than other hypoglycaemic agents, and it has synergistic effects when combined with other antidiabetic drugs, and also has potential in the treatment of T2DM-related complications. This review aims to shed light on the latest research progress in the treatment of T2DM with Imeglimin, thereby providing clinicians and researchers with the latest insights into Imeglimin as a viable option for the treatment of T2DM.

Development of Imeglimin Electrospun Nanofibers as a Potential Buccal Antidiabetic Therapeutic Approach. Pharmaceutics 2023; 15:pharmaceutics15041208. [PMID: 37111693 PMCID: PMC10144366 DOI: 10.3390/pharmaceutics15041208] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/06/2023] [Accepted: 04/05/2023] [Indexed: 04/29/2023] Open
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.

Diabetes Metab Syndr 2023; 17:102710. [PMID: 36702046 DOI: 10.1016/j.dsx.2023.102710] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 01/09/2023] [Accepted: 01/11/2023] [Indexed: 01/22/2023]
Abstract
BACKGROUND & AIMS Imeglimin is a novel new oral compound recently approved for treating type 2 diabetes (T2D) in India. We conducted a systematic review and meta-analysis to evaluate the efficacy of imeglimin in people with T2D in the approved dose of 1000 mg twice daily (BID). METHODS We systematically searched the database of PubMed until December 20, 2022, and retrieved all published double-blind, randomized, placebo-controlled trials (RCTs) conducted with imeglimin 1000 mg BID, using appropriate keywords and MeSH terms. A meta-analysis was conducted to study the HbA1c lowering effect of imeglimin 1000 mg BID in people with T2D using the Comprehensive meta-analysis (CMA) software Version 3, Biostat Inc. Englewood, NJ, USA. RESULTS Of the seven Phase 2 studies and three Phase 3 studies conducted so far, only three published double-blind RCTs have reported the efficacy and safety of imeglimin 1000 mg BID against the placebo. Our meta-analysis using the random-effects model from two monotherapy studies (n = 360) showed imeglimin 1000 mg BID reduce HbA1c significantly (Δ -0.9%, 95% Confidence Interval [CI], -1.1 to -0.74%; P < 0.0001) against the placebo, without any heterogeneity (I2 = 0%). The pooled meta-analysis from all three RCTs (n = 574) found a significant reduction in HbA1c with imeglimin 1000 mg BID (Δ -0.79%; 95% CI, -1.00 to -0.59%; P < 0.0001) compared to placebo with high heterogeneity. CONCLUSIONS This meta-analysis found a significant HbA1c lowering effect of imeglimin in people with T2D with an acceptable tolerability profile. Still, larger and longer studies are needed.

Imeglimin population pharmacokinetics and dose adjustment predictions for renal impairment in Japanese and Western patients with type 2 diabetes. Clin Transl Sci 2021; 15:1014-1026.

Abstract
Imeglimin is an orally administered first-in-class drug to treat type 2 diabetes mellitus (T2DM) and is mainly excreted unchanged by the kidneys. The present study aimed to define the pharmacokinetic (PK) characteristics of imeglimin using population PK analysis and to determine the optimal dosing regimen for Japanese patients with T2DM and chronic kidney disease (CKD). Imeglimin plasma concentrations in Japanese and Western healthy volunteers, and patients with T2DM, including patients with mild to severe CKD with an estimated glomerular filtration rate (eGFR) > 14 mL/min/1.73 m2 were included in a population PK analysis. Pharmacokinetic simulations were conducted using a population PK model, and the area under concentration-time curve (AUC) was extrapolated with power regression analysis to lower eGFR. The influence of eGFR, weight, and age on apparent clearance and of dose on relative bioavailability were quantified by population PK analysis. Simulations and extrapolation revealed that the recommended dosing regimen based on the AUC was 500 mg twice daily (b.i.d.) for patients with eGFR 15-45 mL/min/1.73 m2 , and 500 mg with a longer dosing interval was suggested for those with eGFR < 15. Simulations revealed that differences in plasma AUCs between Japanese and Western patients at the same dose were mainly driven by a difference in the eGFR and that the plasma AUC after 1,000 and 1,500 mg b.i.d. in Japanese and Western patients, respectively, was comparable in the phase IIb studies. These results indicate suitable dosages of imeglimin in the clinical setting of T2DM with renal impairment.

Abstract
Type 2 diabetes (T2D), one of the most prevalent noncommunicable diseases, is often preceded by insulin resistance (IR), which underlies the inability of tissues to respond to insulin and leads to disturbed metabolic homeostasis. Mitochondria, as a central player in the cellular energy metabolism, are involved in the mechanisms of IR and T2D. Mitochondrial function is affected by insulin resistance in different tissues, among which skeletal muscle and liver have the highest impact on whole-body glucose homeostasis. This review focuses on human studies that assess mitochondrial function in liver, muscle and blood cells in the context of T2D. Furthermore, different interventions targeting mitochondria in IR and T2D are listed, with a selection of studies using respirometry as a measure of mitochondrial function, for better data comparison. Altogether, mitochondrial respiratory capacity appears to be a metabolic indicator since it decreases as the disease progresses but increases after lifestyle (exercise) and pharmacological interventions, together with the improvement in metabolic health. Finally, novel therapeutics developed to target mitochondria have potential for a more integrative therapeutic approach, treating both causative and secondary defects of diabetes.

Abstract
Imeglimin is a novel oral antidiabetic drug for treatment of type 2 diabetes that targets mitochondrial bioenergetics. Its pharmacokinetics absorption characteristics, metabolism, distribution, and elimination were assessed through several in vitro and in vivo experiments in both animals and humans. Its potential to induce drug-drug interactions was also extensively assessed. Imeglimin is a small cationic compound with an intermediate intestinal permeability. Its absorption mechanism involves an active transport process in addition to passive paracellular absorption. Absorption was good (50%-80%) in vivo across several species but decreased with increasing dose, probably because of saturation of active transport. After absorption, imeglimin was rapidly and largely distributed to internal organs. Plasma protein binding was low, which can explain the rapid distribution to organs observed in all species. In animals and humans, imeglimin was largely excreted unchanged in urine, indicating a low extent of metabolism. Unchanged drug was the main circulating entity in plasma, and none of the identified metabolites were unique to human. Imeglimin renal clearance was higher than creatinine clearance, indicating that it was actively secreted into urine. There was no evidence that it had the potential to cause cytochrome P450 inhibition or induction. It was shown to be a substrate of organic cation transporter (OCT) 1, OCT2, multidrug and toxin extrusion (MATE) 1, and MATE2-K and an inhibitor of OCT1, OCT2, and MATE1; as a consequence, corresponding clinical drug-drug interaction studies were performed and confirmed the absence of relevant interactions with substrates or inhibitors of these transporters. SIGNIFICANCE STATEMENT: Imeglimin is absorbed through a passive and active mechanism, which can be saturated. It is rapidly and largely distributed to internal organs and mainly excreted unchanged in urine. It is poorly metabolized and has no cytochrome P450 inhibition or induction potential. Imeglimin is a substrate of MATE2-K and also a substrate and an inhibitor of OCT1, OCT2, and MATE1 transporters; however, there are no clinically significant interactions when imeglimin is coadministered with either a substrate or an inhibitor of these transporters.

Abstract
INTRODUCTION Recent advances in anti-diabetic medications and glucose monitoring have led to a paradigm shift in diabetes care. Newer anti-diabetic medications such as DPP-4 inhibitors, GLP-1 receptor agonists (GLP-1RAs), and SGLT2 inhibitors have enabled optimal glycemic control to be achieved without increasing the risk of hypoglycemia and weight gain. Treatment with GLP-1RAs and SGLT2 inhibitors has been demonstrated to improve cardiorenal outcomes, positioning these agents as the mainstay of treatment for patients with type 2 diabetes (T2DM). The development of these newer agents has also prompted a paradigm shift in the concept of T2DM, highlighting the importance of beta cell dysfunction in the pathophysiology of T2DM. AREAS COVERED Recent advances in pharmacotherapy for diabetes are summarized with a focus on the role of incretin-based drugs and SGLT2 inhibitors. The importance of a paradigm shift from a glucose-centric to a beta cell-centric concept of T2DM is also discussed, given from an Asian perspective. EXPERT OPINION Management of T2DM including lifestyle modification as well as pharmacotherapy should be focused on reducing beta cell workload, to preserve functional beta cell mass. A paradigm shift from a glucose-centric to a beta cell-centric concept of T2DM enhances the implementation of person-centered diabetes care.
