Huttasch M, Roden M, Kahl S. Obesity and MASLD: Is weight loss the (only) key to treat metabolic liver disease? Metabolism 2024; 157:155937. [PMID: 38782182 DOI: 10.1016/j.metabol.2024.155937] [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: 08/29/2023] [Revised: 04/25/2024] [Accepted: 05/12/2024] [Indexed: 05/25/2024]
Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD) closely associates with obesity and type 2 diabetes. Lifestyle intervention and bariatric surgery aiming at substantial weight loss are cornerstones of MASLD treatment by improving histological outcomes and reducing risks of comorbidities. Originally developed as antihyperglycemic drugs, incretin (co-)agonists and SGLT2 inhibitors also reduce steatosis and cardiorenovascular events. Certain incretin agonists effectively improve histological features of MASLD, but not fibrosis. Of note, beneficial effects on MASLD may not necessarily require weight loss. Despite moderate weight gain, one PPARγ agonist improved adipose tissue and MASLD with certain benefit on fibrosis in post-hoc analyses. Likewise, the first THRβ-agonist was recently provisionally approved because of significant improvements of MASLD and fibrosis. We here discuss liver-related and metabolic effects induced by different MASLD treatments and their association with weight loss. Therefore, we compare results from clinical trials on drugs acting via weight loss (incretin (co)agonists, SGLT2 inhibitors) with those exerting no weight loss (pioglitazone; resmetirom). Furthermore, other drugs in development directly targeting hepatic lipid metabolism (lipogenesis inhibitors, FGF21 analogs) are addressed. Although THRβ-agonism may effectively improve hepatic outcomes, MASLD treatment concepts should consider all cardiometabolic risk factors for effective reduction of morbidity and mortality in the affected people.

A Randomized Crossover Trial of Mixed Meal Tolerance Test Response in People with Type 1 Diabetes on Insulin Pump Therapy and YG1699 or Dapagliflozin. Clin Pharmacol Ther 2024; 115:1383-1390. [PMID: 38456487 DOI: 10.1002/cpt.3225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Accepted: 02/13/2024] [Indexed: 03/09/2024]
Abstract
YG1699 is a novel inhibitor of sodium-glucose cotransporter 1 (SGLT1) and SGLT2. This double-blind, 3-way crossover trial compared YG1699 to dapagliflozin as an adjunct to insulin in people with type 1 diabetes (T1D) on insulin pump therapy. Treatment periods included four mixed meal tolerance tests (MMTTs) and insulin withdrawal tests per person. Nineteen adults with T1D were randomized to YG1699 10 mg, YG1699 25 mg, and dapagliflozin 10 mg once daily for 1 week in different orders. The primary end point was the difference in area under the curve (AUC) in plasma glucose (AUC0-120min) after an MMTT between treatment groups. Mean change in plasma glucose after an MMTT (AUC0-120min) was lower for YG1699 10 mg vs. dapagliflozin (89.51% of baseline vs. 102.13%, 90% confidence interval (CI) vs. dapagliflozin, -6% to -16%, P = 0.0003) and for YG1699 25 mg (84.83% vs. 102.13%, 90% CI vs. dapagliflozin -13% to -22%, P < 0.0001). At 120 minutes, mean glucose values on no treatment, dapagliflozin, YG1699 10 mg, and YG1699 25 mg were 149 (SE 7.6), 141 (SE 6.1), 128 (SE 6.9), and 115 (SE 7.8) mg/dL, respectively. Insulin dose requirements were lower for YG1699 10 mg and 25 mg vs. dapagliflozin for bolus insulin, and for YG1699 10 mg vs. dapagliflozin for total daily insulin. Safety profiles were similar between treatment groups. YG1699 reduced post-prandial glucose more than dapagliflozin in people with T1D on insulin pump therapy. The results were consistent with dual SGLT1/SGLT2 inhibition by YG1699.

Cardioprotective Effects of Sodium-Glucose Cotransporter Subtype Inhibition on Ischemic and Pharmacological Preconditioning. Cureus 2024; 16:e59757. [PMID: 38841006 PMCID: PMC11152766 DOI: 10.7759/cureus.59757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/06/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND Sodium-glucose cotransporter (SGLT) 2 inhibitors partially inhibit SGLT1 expression; however, whether a clinical dose of SGLT2 inhibitor abrogates ischemic preconditioning (IPC) is unknown, and the pharmacological cardioprotective effect under SGLT1 inhibition has not been examined. In this study, we investigated whether a clinical dose of tofogliflozin abrogates IPC and whether pharmacological preconditioning with olprinone has cardioprotective effects under SGLT1 inhibition. METHODS Male Wistar rats were divided into seven groups (seven rats per group) and subjected to the following treatments before inducing ischemia/reperfusion (I/R; 30 minutes of coronary artery occlusion followed by 120 minutes of reperfusion): saline infusion control treatment (Con); ischemic preconditioning (IPC); IPC after phlorizin infusion (IPC+Phl); IPC after low-dose tofogliflozin infusion (IPC+L-Tof); IPC after high-dose tofogliflozin infusion (IPC+H-Tof); olprinone infusion (Olp); and Olp infusion after phlorizin infusion (Olp+Phl). RESULTS The infarct size was significantly decreased in the IPC group, but not in the IPC+Phl group. In contrast, the infarct size decreased in the IPC+L-Tof and IPC+H-Tof groups. Additionally, Olp reduced the infarct size, and the effect was preserved in Olp+Phl groups. Phosphorylated AMP-activated protein kinase (AMPK) expression was lower in the IPC+Phl group compared to that in the IPC group. CONCLUSION The cardioprotective effect of IPC was attenuated by strong SGLT1 inhibition, but the effect was preserved under a clinical dose of highly selective SGLT2 inhibitor. Olprinone exerts a cardioprotective effect even under strong SGLT1 inhibition.

Effect of SGLT2 Inhibitors on Improving Glucolipid Metabolism and Reproductive Hormone Status in Overweight/Obese Women with PCOS: A Systematic Review and Meta-Analysis. Reprod Sci 2024; 31:1190-1203.

Abstract
BACKGROUND Obesity, insulin resistance, and hyperandrogenemia are commonly seen in women with polycystic ovary syndrome (PCOS), and these three conditions form a vicious cycle leading to reproductive and metabolic abnormalities. Metformin improves the symptoms of PCOS by increasing insulin sensitivity but is not therapeutically optimal. Recent studies have reported that sodium-glucose co-transporter protein receptor inhibitors improve insulin resistance and reduce the weight of patients with PCOS. We performed a meta-analysis to assess the influence of sodium-glucose co-transporter protein-2 (SGLT2) inhibitors on anthropometric, glycolipid metabolism and reproductive outcomes after therapy of overweight/obese women with PCOS. METHODS We searched the relevant literature published up to April 2023. Information on the effect of SGLT2 inhibitors on overweight/obese patients with PCOS was extracted independently by two reviewers. Review Manager 5.3 was used for meta-analysis. RESULTS Five randomized controlled trials that met our criteria were retrieved. Our meta-analysis demonstrated that in overweight/obese patients with PCOS, SGLT2 inhibitors treatment was significantly superior to metformin treatment in terms of reducing body weight (P = 0.02, I2 = 36%), decreasing dehydroepiandrosterone sulfate concentrations [SMD = -0.42, 95% CI (-0.76, -0.07), I2 = 22%, P = 0.02], and reducing the incidence of nausea [RR = 0.35, 95% CI (0.21, 0.60), I2 = 71%, P = 0.0001]. CONCLUSIONS SGLT2 inhibitors are a possible alternative therapy for treating overweight/obese women with PCOS who do not respond favorably to metformin treatment. However, further large randomized controlled trials and cost-effectiveness analyses are warranted to guide the implementation of SGLT2 inhibitors treatment in this population.

Risks and Benefits of SGLT-2 Inhibitors for Type 1 Diabetes Patients Using Automated Insulin Delivery Systems-A Literature Review. Int J Mol Sci 2024; 25:1972. [PMID: 38396657 PMCID: PMC10888162 DOI: 10.3390/ijms25041972] [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: 12/04/2023] [Revised: 01/27/2024] [Accepted: 02/04/2024] [Indexed: 02/25/2024] Open
Abstract
The primary treatment for autoimmune Diabetes Mellitus (Type 1 Diabetes Mellitus-T1DM) is insulin therapy. Unfortunately, a multitude of clinical cases has demonstrated that the use of insulin as a sole therapeutic intervention fails to address all issues comprehensively. Therefore, non-insulin adjunct treatment has been investigated and shown successful results in clinical trials. Various hypoglycemia-inducing drugs such as Metformin, glucagon-like peptide 1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors, amylin analogs, and Sodium-Glucose Cotransporters 2 (SGLT-2) inhibitors, developed good outcomes in patients with T1DM. Currently, SGLT-2 inhibitors have remarkably improved the treatment of patients with diabetes by preventing cardiovascular events, heart failure hospitalization, and progression of renal disease. However, their pharmacological potential has not been explored enough. Thus, the substantial interest in SGLT-2 inhibitors (SGLT-2is) underlines the present review. It begins with an overview of carrier-mediated cellular glucose uptake, evidencing the insulin-independent transport system contribution to glucose homeostasis and the essential roles of Sodium-Glucose Cotransporters 1 and 2. Then, the pharmacological properties of SGLT-2is are detailed, leading to potential applications in treating T1DM patients with automated insulin delivery (AID) systems. Results from several studies demonstrated improvements in glycemic control, an increase in Time in Range (TIR), a decrease in glycemic variability, reduced daily insulin requirements without increasing hyperglycemic events, and benefits in weight management. However, these advantages are counterbalanced by increased risks, particularly concerning Diabetic Ketoacidosis (DKA). Several clinical trials reported a higher incidence of DKA when patients with T1DM received SGLT-2 inhibitors such as Sotagliflozin and Empagliflozin. On the other hand, patients with T1DM and a body mass index (BMI) of ≥27 kg/m2 treated with Dapagliflozin showed similar reduction in hyperglycemia and body weight and insignificantly increased DKA incidence compared to the overall trial population. Additional multicenter and randomized studies are required to establish safer and more effective long-term strategies based on patient selection, education, and continuous ketone body monitoring for optimal integration of SGLT-2 inhibitors into T1DM therapeutic protocol.

Abstract
Obesity is a multifactorial disease that represents a substantial global health concern. As of 2016, the World Health Organization (WHO) estimated that over 650 million adults were obese, and more than 1.9 billion were overweight. Surgical interventions or lifestyle changes are typically suggested to patients who experience comorbidities as a result of their weight; however, more recently, antidiabetic medications have been proposed, specifically sodium-glucose cotransporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1RAs). This is the first systematic review to evaluate the safety, efficacy, and future role of SGLT-2 inhibitors and GLP-1RAs for weight loss in the world of aesthetic plastic surgery. Sixteen randomized controlled trials were identified that met the eligibility criteria for this systematic review and comprised data from 10,492 patients. All studies reported a decline in body weight following treatment with SGLT-2 inhibitors or GLP-1RAs, ranging from 1.5 to 5 kg. Although adverse events were reported in a large proportion of patients, primarily gastrointestinal manifestations, the literature reports that these were mild to moderate in severity and tended to subside following treatment adjustment. Future research is warranted to determine the ideal SGLT-2 inhibitor or GLP-1RA for weight loss management, and additional randomized controlled trials (RCTs) are needed to determine the efficacy and tolerability of potential combination therapies with SGLT-2 inhibitors and GLP-1RAs.

Abstract
Diabetes Mellitus Type 2 (T2D) is an emerging health burden in the USand worldwide, impacting approximately 15% of Americans. Current front-line therapeutics for T2D patients include sulfonylureas that act to reduce A1C and/or fasting blood glucose levels, or Metformin that antagonizes the action of glucagon to reduce hepatic glucose production. Next generation glucomodulatory therapeutics target members of the high-affinity glucose transporter Sodium-Glucose-Linked-Transporter (SGLT) family. SGLT1 is primarily expressed in intestinal epithelium, whose inhibition reduces dietary glucose uptake, whilst SGLT2 is highly expressed in kidney - regulating glucose reabsorption. A number of SGLT2 inhibitors are FDA approved whilst SGLT1 and dual SGLT1 & 2 inhibitor are currently in clinical trials. Here, we discuss and compare SGLT2, SGLT1, and dual inhibitors' biochemical mechanism and physiological effects.

Abstract
Virtual small molecule libraries are valuable resources for identifying bioactive compounds in virtual screening campaigns and improving the quality of libraries in terms of physicochemical properties, complexity, and structural diversity. In this context, the computational-aided design of libraries focused against antidiabetic targets can provide novel alternatives for treating type II diabetes mellitus (T2DM). In this work, we integrated the information generated to date on compounds with antidiabetic activity, advances in computational methods, and knowledge of chemical transformations available in the literature to design multi-target compound libraries focused on T2DM. We evaluated the novelty and diversity of the newly generated library by comparing it with antidiabetic compounds approved for clinical use, natural products, and multi-target compounds tested in vivo in experimental antidiabetic models. The designed libraries are freely available and are a valuable starting point for drug design, chemical synthesis, and biological evaluation or further computational filtering. Also, the compendium of 280 transformation rules identified in a medicinal chemistry context is made available in the linear notation SMIRKS for use in other chemical library enumeration or hit optimization approaches.

Abstract
Sodium glucose cotransporters (SGLTs) are transport proteins that are expressed throughout the body. Inhibition of SGLTs is a relatively novel therapeutic strategy to improve glycemic control and has been shown to promote cardiorenal benefits. Dual SGLT1/2 inhibitors (SGLT1/2i) such as sotagliflozin target both SGLT1 and 2 proteins. Sotagliflozin or vehicle was administered to diabetic Akimba mice for 8 weeks at a dose of 25 mg/kg/day. Urine glucose levels, water consumption, and body weight were measured weekly. Serum, kidney, pancreas, and brain tissue were harvested under terminal anesthesia. Tissues were assessed using immunohistochemistry or ELISA techniques. Treatment with sotagliflozin promoted multiple metabolic benefits in diabetic Akimba mice resulting in decreased blood glucose and improved polydipsia. Sotagliflozin also prevented mortalities associated with diabetes. Our data suggests that there is the possibility that combined SGLT1/2i may be superior to SGLT2i in controlling glucose homeostasis and provides protection of multiple organs affected by diabetes.

Abstract
Non-alcoholic fatty liver disease (NAFLD) has no approved pharmacological treatments. Sodium-glucose cotransporter (SGLT)-1 is a glucose transporter that mediates small intestinal glucose absorption. We evaluated the impact of genetically proxied SGLT-1 inhibition (SGLT-1i) on serum liver transaminases and NAFLD risk. We used a missense variant, rs17683430, in the SLC5A1 gene (encoding SGLT1) associated with HbA1c in a genome-wide association study (n = 344 182) to proxy SGLT-1i. Outcome genetic data comprised 1483 NAFLD cases and 17 781 controls. Genetically proxied SGLT-1i was associated with reduced NAFLD risk (OR 0.36; 95%CI 0.15, 0.87; P = .023) per 1 mmol/mol HbA1c reduction, and with reductions in liver enzymes (alanine transaminase, aspartate transaminase, gamma-glutamyl transferase). Genetically proxied HbA1c, not specifically via SGLT-1i, was not associated with NAFLD risk. Colocalisation did not demonstrate genetic confounding. Overall, genetically proxied SGLT-1i is associated with improved liver health, this may be underpinned by SGLT-1-specific mechanisms. Clinical trials should evaluate the impact of SGLT-1/2 inhibitors on the prevention and treatment of NAFLD.

Abstract
Multifactorial diseases exhibit a complex pathophysiology with several factors contributing to their pathogenesis and development. Examples of such disorders are neurodegenerative (e. g. Alzheimer's, Parkinson's) and cardiovascular diseases (e. g. atherosclerosis, metabolic syndrome, diabetes II). Traditional therapeutic approaches with single-target drugs have been proven, in many cases, unsatisfactory for the treatment of multifactorial diseases such as diabetes II. The well-established by now strategy of multitarget drugs is constantly gaining interest and momentum, as a more effective approach. The development of pharmacomolecules able to simultaneously modulate multiple relevant-to-the-disease targets has already several successful examples in various fields and has, as such, inspired the design of multitarget antidiabetic agents; this review highlights the design aspect and efficacy of this approach for improved antidiabetics by presenting several examples of successful pharmacophore combinations in (multitarget) agents that modulate two or more molecular targets involved in diabetes II, resulting in a superior antihyperglycemic profile.

Abstract
BACKGROUND AND AIM Licogliflozin is a dual SGLT1/2 inhibitor acting on the intestine and kidney by reducing glycemic and calorie content. We aimed to determine the efficacy and safety of licogliflozin on Anthropometric measurements and cardiometabolic parameters in obese participants. METHODS We systematically searched the PubMed, Cochrane Library, Scopus, and Web of Science databases for randomized controlled trials (RCTs) relevant to our eligibility criteria. We performed a subgroup analysis based on licogliflozin doses and the diabetic state of participants. This meta-analysis was registered on PROSPERO (CRD42021286936). RESULTS We identified five RCTs with a total of 905 obese and overweight participants. All participants had a weight reduction of 2.43 kg (95% CI: -3.17 to -1.69, p < 0.00001) compared with placebo. The mean difference in HbA1c of obese diabetic patients was (MD: -0.30%; 95% CI: -0.45, -0.16); I2 = 46% in favor of licogliflozin. The incidence of serious adverse events, all-cause mortality, headache, nausea, and vomiting were similar between licogliflozin and placebo (p = 0.72, 0.97, 0.09, 0.53, and 0.89, respectively). However, there was a higher incidence of diarrhea in the licogliflozin group. CONCLUSION We found that licogliflozin was safe and tolerable. It reduces body weight significantly. Moreover, it improves glycemic control and other cardiometabolic parameters.

Abstract
Nonalcoholic steatohepatitis (NASH) is a common chronic liver disease that may advance to fibrosis and lead to mortality; however, no pharmacotherapy is currently available. We tested the hypothesis that inhibition of both the sodium-glucose cotransporters 1 and 2 with licogliflozin would lead to improvement in NASH. A total of 107 patients with phenotypic or histologic NASH were randomized (1:2:2) to receive oral administration of either placebo (n = 21), licogliflozin 30 mg (n = 43) or 150 mg (n = 43) once daily for 12 weeks. Licogliflozin 150 mg showed a significant 32% (80% confidence interval (CI): 21-43%; P = 0.002) placebo-adjusted reduction in serum alanine aminotransferase after 12 weeks of treatment, the primary endpoint of the study. However, the 30 mg dose of licogliflozin did not meet the primary endpoint (placebo-adjusted reduction 21% (80% CI: 7-32%; P = 0.061)). Diarrhea occurred in 77% (33 of 43), 49% (21 of 43) and 43% (9 of 21) of patients treated with licogliflozin 150 mg, 30 mg and placebo, respectively, which was mostly mild in severity. No other major safety concerns were identified. Treatment with 150 mg licogliflozin led to reductions in serum alanine aminotransferase in patients with NASH. Studies of longer duration and in combination with drugs that have different mechanisms of action are needed to validate these findings and to define a role of licogliflozin as a therapeutic option for NASH. ClinicalTrials.gov identifier: NCT03205150.

Abstract
Glucose-dependent insulinotropic polypeptide (GIP) is released from the upper small intestine in response to food intake and contributes to the postprandial control of nutrient disposition, including of sugars and fats. Long neglected as a potential therapeutic target, the GIPR axis has received increasing interest recently, with the emerging data demonstrating the metabolically favorable outcomes of adding GIPR agonism to GLP-1 receptor agonists in people with type 2 diabetes and obesity. This review examines the physiology of the GIP axis, from the mechanisms underlying GIP secretion from the intestine to its action on target tissues and therapeutic development. Expected final online publication date for the Annual Review of Nutrition, Volume 42 is August 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Abstract
Recent insights into the pathophysiologic underlying mechanisms of obesity have led to the discovery of several promising drug targets and novel therapeutic strategies to address the global obesity epidemic and its comorbidities. Current pharmacologic options for obesity management are largely limited in number and of modest efficacy/safety profile. Therefore, the need for safe and more efficacious new agents is urgent. Drugs that are currently under investigation modulate targets across a broad range of systems and tissues, including the central nervous system, gastrointestinal hormones, adipose tissue, kidney, liver, and skeletal muscle. Beyond pharmacotherapeutics, other potential antiobesity strategies are being explored, including novel drug delivery systems, vaccines, modulation of the gut microbiome, and gene therapy. The present review summarizes the pathophysiology of energy homeostasis and highlights pathways being explored in the effort to develop novel antiobesity medications and interventions but does not cover devices and bariatric methods. Emerging pharmacologic agents and alternative approaches targeting these pathways and relevant research in both animals and humans are presented in detail. Special emphasis is given to treatment options at the end of the development pipeline and closer to the clinic (ie, compounds that have a higher chance to be added to our therapeutic armamentarium in the near future). Ultimately, advancements in our understanding of the pathophysiology and interindividual variation of obesity may lead to multimodal and personalized approaches to obesity treatment that will result in safe, effective, and sustainable weight loss until the root causes of the problem are identified and addressed.

Abstract
Non-alcoholic fatty liver disease (NAFLD), or metabolic (dysfunction)-associated fatty liver disease (MAFLD), is characterized by high global incidence and prevalence, a tight association with common metabolic comorbidities, and a substantial risk of progression and associated mortality. Despite the increasingly high medical and socioeconomic burden of NAFLD, the lack of approved pharmacotherapy regimens remains an unsolved issue. In this paper, we aimed to provide an update on the rapidly changing therapeutic landscape and highlight the major novel approaches to the treatment of this disease. In addition to describing the biomolecules and pathways identified as upcoming pharmacological targets for NAFLD, we reviewed the current status of drug discovery and development pipeline with a special focus on recent evidence from clinical trials.

Abstract
OBJECTIVES Canagliflozin (CANA), a kind of sodium-glucose cotransporter-2 (SGLT-2) inhibition, study in which the role of CANA monotherapy in polycystic ovary syndrome (PCOS) has been investigated, and it could become a novel option in the PCOS treatment. Nevertheless, trials focused on SGLT-2 combination therapy's efficacy, and safety in PCOS patients are limited. This randomized controlled trial compared the efficacy and safety of CANA and metformin (MET) combination therapy and MET monotherapy in endocrine and metabolic profiles of overweight and obese women with polycystic ovary syndrome (PCOS). METHODS Fifty-one overweight or obese non-diabetic PCOS women between 18 and 40 years old were enrolled. Patients were randomly allocated to receive either CANA/MET or MET treatment. The CANA/MET group received CANA 100 mg once daily plus MET 1000 mg twice daily, while the MET group received MET 1000 mg twice daily for three months. Changes in menstrual pattern, anthropometric parameters, gonadal parameters, glucose and lipid homeostasis, and adverse events (AEs) were evaluated. RESULTS Compared with the MET group, women have a significantly lower level of total testosterone (TT), area under the curve for glucose (AUCGlu), and area under the curve for insulin (AUCIns) to AUCGlu ratio in the combination group. There were no significant differences in menstrual frequency, body weight, body mass index, follicle-stimulating hormone, luteinizing hormone, free androgen index, sex hormone-binding globulin, androstenedione, fasting blood glucose, fasting insulin, AUCIns, homeostasis model assessment-insulin resistance (HOMA-IR), triglycerides, total cholesterol, low-density lipoprotein cholesterol, apolipoprotein A1 (Apo A1), apolipoprotein B (Apo B), and APO B/A1 ratio. AEs were seen in 57.70% (15/26) and 68.00% (17/25) of patients in the CANA/MET and MET groups, respectively. CONCLUSIONS In overweight and obese women with PCOS, CANA and MET combination therapy may be similar to MET monotherapy in improving menstrual frequency, weight control, hyperandrogenemia, and relieving insulin resistance. CANA/MET may have more benefits in reducing TT, AUCGlu, and the AUCIns/AUCGlu ratio within three months than MET monotherapy. TRIAL REGISTRATION ClinicalTrials.gov, NCT04973891.

Abstract
BACKGROUND We aimed to evaluate the efficacy of sodium-glucose cotransporter 2 (SGLT2) inhibitors for managing obesity in non-diabetic overweight or obese patients. METHODS For purposes of this study, PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were searched through May 2021. Randomized controlled trials published in English that compared SGLT2 inhibitors with placebo in overweight and obese patients without diabetes were included in the primary analysis. The random effects standardized mean difference ±95% confidence interval (95% CI) was calculated as the effect size. RESULTS Five randomized controlled trials were included to evaluate body weight change, four trials to assess body mass index (BMI), and three trials to assess waist circumference were included. Results showed that the mean body weight loss on SGLT2 inhibitors in obese patients without diabetes was -1.62 kg (95% CI, -2.38 to -0.85 kg) when compared with placebo. Treatment with SGLT2 inhibitors was also associated with a greater reduction in BMI than placebo (weighted mean difference, -0.47 kg/m2; 95% CI, -0.62 to -0.31 kg/m2). The mean reduction in waist circumference with SGLT2 inhibitors versus placebo was 1.29 cm (95% CI, -2.62 to 0.04 cm), which was not statistically significant. There were no significant changes in fat mass, blood pressure, low-density lipoprotein cholesterol or high-density lipoprotein cholesterol with SGLT2 inhibitor treatment. CONCLUSION A meta-analysis demonstrated that although the weight lowering effect was mild, SGLT2 inhibitors significantly reduced body weight in obese patients without diabetes.

Abstract
Several meta-analyses have been conducted to evaluate the weight loss effect of sodium-glucose cotransporter 2 (SGLT-2) inhibitors in patients with type 2 diabetes, whereas pooled analysis focusing on individuals without diabetes is lacking. The objective of this systematic review and meta-analysis is to evaluate the effect of SGLT-2 inhibitor monotherapy on weight change and cardiometabolic profiles. Multiple databases were searched for randomized controlled trials reporting weight change effect of SGLT-2 inhibitor treatment compared with placebo for more than 12 weeks among individuals with overweight or obesity and without diabetes. A total of eight randomized controlled trials with 750 subjects were identified. SGLT-2 monotherapy was associated with significant reduction in body weight of -2.32 kg, compared to -1.01 kg for placebo, giving a mean difference of -1.31 kg. Significant reductions in body mass index and fasting blood glucose were observed, but not for the changes in waist circumference, fat mass, blood pressure, and lipid profile compared with placebo. SGLT-2 inhibitor monotherapy for 12 weeks or more can result in modest weight loss among people with overweight or obesity and without diabetes. Depending on pre-existing comorbidities or risk factors, SGLT-2 inhibitors can be considered adjuncts in the treatment of obesity.

Abstract
The kidney plays a major physiological role in glucose homeostasis but also contributes to the pathophysiology of type 2 diabetes (T2D), mediated by renal sodium glucose cotransporters (SGLTs). This recognition led to the development of SGLT2 inhibitors that inhibit proximal renal tubular renal glucose and sodium reabsorption. The glucoretic and natriuretic effect of SGLT2 inhibitors is associated with reductions in HbA1c levels, body weight, systolic blood pressure and triglycerides. Major vascular complications of T2D include cardiovascular disease and chronic kidney disease (CKD). Results from several cardiovascular outcome trials (CVOTs) with these drugs have highlighted benefits in reducing major adverse cardiovascular events by 11%, reducing the risk of cardiovascular death or hospitalization for heart failure (HF) by 23% and reducing the risk of progression of renal disease by 45%. Their cardiorenal benefits are apparent across a range of eGFRs (within CKD1-3 groups) and the presence or absence of ischaemic heart disease, HF or T2D. In patients with HF with reduced ejection fraction (HFrEF), similar risk reductions in cardiovascular death and HF events are also seen; results from studies in patients with HF with preserved ejection fraction (HFpEF) are awaited. Cardiorenal benefits have been recently reported in patients with CKD, regardless of the presence or absence of T2D. Indications for use of SGLT2 inhibitors have extended beyond glucose-lowering to a central role in cardiorenal protection. This review will first explore the mechanisms by which glycaemic control, weight loss and cardiovascular risk factors are modulated therapeutically with SGLT2 inhibitors. Subsequently, we outline putative mechanisms underpinning the cardiorenal benefits seen, including in HF and CKD, in the context of completed and ongoing clinical studies. Treatment strategies with SGLT2 inhibitors in individuals with CKD or HF, with and/or without T2D are increasingly appealing. Combination therapy with complementary therapeutic agents is also explored.

Licogliflozin versus placebo in women with polycystic ovary syndrome: A randomized, double-blind, phase 2 trial. Diabetes Obes Metab 2021; 23:2595-2599. [PMID: 34263971 DOI: 10.1111/dom.14495] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 06/28/2021] [Accepted: 07/12/2021] [Indexed: 12/27/2022]
Abstract
Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism and insulin resistance. The dual sodium-glucose co-transporter 1/2 inhibitor (SGLT1/2i) licogliflozin (LIK066) ameliorates hyperinsulinism in patients with diabetes and obesity. This study examines the effect of licogliflozin on androgens in women with PCOS. In a multicentre, randomized, placebo-controlled, double-blind, 2-week trial, patients with PCOS received licogliflozin 50 mg or placebo three times a day (TID). Changes in free testosterone (FT), other androgens and variables of insulin resistance were analysed. Concentration of FT did not change (TRLIK066 :TRPCB [FT]: 0.88; 90% CI: 0.70-1.11; P = .353). Licogliflozin reduced androstendione (A4) by 19% (TRLIK066 :TRPCB [A4]: 0.81; 90% CI: 0.68-0.99; P = .089) and dehydroepiandrosteron sulphate (DHEAS) by 24% (TRLIK066 :TRPCB [DHEAS]: 0.76; 90% CI: 0.65-0.89; P = .008). Hyperinsulinaemia was reduced by 70% by licogliflozin (highest insulin concentration [MAXI]; TRLIK066 :TRPCB [MAXI]: 0·26; 90% CI:0.20-0.34; P < .001 and area under the curve insulin [AUCI]; TRLIK066 :TRPCB [AUCI]: 0.32; 90% CI: 0.25-0.41; P < .001). Diarrhoea and nausea occurred as common adverse events. Dual inhibition of SGLT1/2 ameliorates hyperinsulinaemia and hyperandrogenaemia in women with PCOS. Licogliflozin may represent a promising novel treatment option for PCOS.

[PMID: 34589201 PMCID: PMC8474306 DOI: 10.1177/20420188211042145] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 08/06/2021] [Indexed: 12/18/2022] Open
Abstract
Diabetes mellitus (DM) is a chronic, progressive, and multifaceted illness resulting in significant physical and psychological detriment to patients. As of 2019, 463 million people are estimated to be living with DM worldwide, out of which 90% have type-2 diabetes mellitus (T2DM). Over the years, significant progress has been made in identifying the risk factors for developing T2DM, understanding its pathophysiology and uncovering various metabolic pathways implicated in the disease process. This has culminated in the implementation of robust prevention programmes and the development of effective pharmacological agents, which have had a favourable impact on the management of T2DM in recent times. Despite these advances, the incidence and prevalence of T2DM continue to rise. Continuing research in improving efficacy, potency, delivery and reducing the adverse effect profile of currently available formulations is required to keep pace with this growing health challenge. Moreover, new metabolic pathways need to be targeted to produce novel pharmacotherapy to restore glucose homeostasis and address metabolic sequelae in patients with T2DM. We searched PubMed, MEDLINE, and Google Scholar databases for recently included agents and novel medication under development for treatment of T2DM. We discuss the pathophysiology of T2DM and review how the emerging anti-diabetic agents target the metabolic pathways involved. We also look at some of the limiting factors to developing new medication and the introduction of unique methods, including facilitating drug delivery to bypass some of these obstacles. However, despite the advances in the therapeutic options for the treatment of T2DM in recent years, the industry still lacks a curative agent.

Influence of receptor selectivity on benefits from SGLT2 inhibitors in patients with heart failure: a systematic review and head-to-head comparative efficacy network meta-analysis. Clin Res Cardiol 2021; 111:428-439.

Abstract
Background Receptor selectivity of sodium-glucose cotransporter-2 inhibitors (SGLT2i) varies greatly between agents. The overall improvement of cardiovascular (CV) outcomes in heart failure (HF) patients varies between trials. We, therefore, evaluated the comparative efficacy of individual SGLT2i and the influence of their respective receptor selectivity thereon. Methods We identified randomized controlled trials investigating the use of SGLT2i in patients with HF—either as the target cohort or as a subgroup of it. Comparators included placebo or any other active treatment. The primary endpoint was the composite of hospitalization for HF or CV death. Secondary outcomes included all-cause mortality, CV mortality, hospitalization for HF, worsening renal function (RF), and the composite of worsening RF or CV death. Evidence was synthesized using network meta-analysis. In addition, the impact of receptor selectivity on outcomes was analysed using meta-regression. Results We identified 18,265 patients included in 22 trials. Compared to placebo, selective and non-selective SGLT2i improved fatal and non-fatal HF events. Head-to-head comparisons suggest superior efficacy with sotagliflozin as compared to dapagliflozin, empagliflozin or ertugliflozin. No significant difference was found between canagliflozin and sotagliflozin. Meta-regression analyses show a decreasing benefit on HF events with increasing receptor selectivity of SGLT2i. In contrast, receptor selectivity did not affect mortality and renal endpoints and no significant difference between individual SGLT2i was noted. Conclusion Our data point towards a class-effect of SGLT2i on mortality and renal outcomes. However, non-selective SGLT2i such as sotagliflozin may be superior to highly selective SGLT2i in terms of HF outcomes.

Abstract
The global epidemic of non-alcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH) and the high prevalence among individuals with type 2 diabetes has attracted the attention of clinicians specialising in liver disorders. Many drugs are in the pipeline for the treatment of NAFLD/NASH, and several glucose-lowering drugs are now being tested specifically for the treatment of liver disease. Among these are nuclear hormone receptor agonists (e.g. peroxisome proliferator-activated receptor agonists, farnesoid X receptor agonists and liver X receptor agonists), fibroblast growth factor-19 and -21, single, dual or triple incretins, sodium-glucose cotransporter inhibitors, drugs that modulate lipid or other metabolic pathways (e.g. inhibitors of fatty acid synthase, diacylglycerol acyltransferase-1, acetyl-CoA carboxylase and 11β-hydroxysteroid dehydrogenase type-1) or drugs that target the mitochondrial pyruvate carrier. We have reviewed the metabolic effects of these drugs in relation to improvement of diabetic hyperglycaemia and fatty liver disease, as well as peripheral metabolism and insulin resistance.

Abstract
INTRODUCTION Given the relationship between the pathogenesis of obesity and type 2 diabetes mellitus (T2DM) as well as their significant health consequences, treatment strategies that can induce weight loss while achieving glycemic control are needed. Novel weight-reducing anti-diabetic agents along with anti-obesity medications (AOMs) can help medical providers address both conditions simultaneously and effectively. AREAS COVERED This review summarizes and compares weight loss efficacy and glycemic control of weight-reducing anti-diabetic medications, AOMs and emerging pharmacologic agents that help treat both obesity and T2DM. EXPERT OPINION Management of obesity and T2DM can be challenging to achieve and sustain in the presence of obesogenic anti-diabetic agents. Utilizing weight-reducing anti-diabetic agents, AOMs, and endobariatric or surgical procedures, either separately or in combination, can help achieve better clinical outcomes in patients with obesity and T2DM. Some agents in development, such as tirzepatide and bimagrumab, are promising pharmacotherapy options that may change the standards of care for cardiometabolic disease management.

Abstract
The novel SARS-CoV-2 uses ACE2 (Angiotensin-Converting Enzyme 2) receptor as an entry point. Insights on S protein receptor-binding domain (RBD) interaction with ACE2 receptor and drug repurposing has accelerated drug discovery for the novel SARS-CoV-2 infection. Finding small molecule binding sites in S protein and ACE2 interface is crucial in search of effective drugs to prevent viral entry. In this study, we employed molecular dynamics simulations in mixed solvents together with virtual screening to identify small molecules that could be potential inhibitors of S protein -ACE2 interaction. Observation of organic probe molecule localization during the simulations revealed multiple sites at the S protein surface related to small molecule, antibody, and ACE2 binding. In addition, a novel conformation of the S protein was discovered that could be stabilized by small molecules to inhibit attachment to ACE2. The most promising binding site on RBD-ACE2 interface was targeted with virtual screening and top-ranked compounds (DB08248, DB02651, DB03714, and DB14826) are suggested for experimental testing. The protocol described here offers an extremely fast method for characterizing key proteins of a novel pathogen and for the identification of compounds that could inhibit or accelerate spreading of the disease.

Abstract
Introduction: Post-pancreatitis diabetes mellitus is one of the most common types of secondary diabetes. The pharmaceutical armamentarium in the field of diabetology can be broadened if the design of novel drugs is informed by pathogenetic insights from studies on post-pancreatitis diabetes mellitus.Areas covered: The article provides an overview of preclinical and clinical studies of compounds selectively antagonizing the gastric inhibitory peptide receptor, simultaneously stimulating both the glucagon-like peptide-1 and glucagon receptors, and activating ketogenesis.Expert opinion: The current pharmacotherapy for post-pancreatitis diabetes mellitus is relatively ineffective. This type of diabetes represents a unique platform for rigorous, efficient, and practical search for glucose-lowering therapeutic candidates. Various methods of gastric inhibitory peptide receptor (expressed in the pancreas) antagonism have undergone extensive preclinical testing in diabetes, with promising compounds being trialed in man. Molecular mimicry with oxyntomodulin ─ an extra-pancreatic hormone homologous with pancreatic hormone glucagon and involved in the regulation of exocrine pancreatic function ─ could be harnessed. The emerging findings of a salutary effect of ketosis mimetics in people with prediabetes set the stage for a novel approach to preventing diabetes.

Abstract
AIM To investigate the glucosuric, renal and haemodynamic effects of licogliflozin, a dual sodium-glucose co-transporter-1 and sodium-glucose co-transporter-2 inhibitor, in patients with chronic kidney disease (CKD). METHODS This multiple-dose, parallel-group, phase II mechanistic study randomized 53 participants (aged 18-78 years, body mass index ≤ 50 kg/m2 ) with varying degrees of CKD or normal renal function to treatment with licogliflozin (50 mg once daily) or placebo for 7 days. The effects of licogliflozin on 24-h urinary glucose excretion (UGE24 ), renal function, haemodynamics, pharmacokinetics and safety were assessed. RESULTS Licogliflozin treatment for 7 days significantly (p < .01) increased UGE24 from baseline in participants with normal renal function (adjusted mean change: 41.8 [33.6, 49.9] g) or with mild (32.6 [24.1, 41.0] g), moderate A (35.7 [28.6, 42.9] g) or moderate B (20.3 [13.1, 27.5] g) CKD, but not in severe (6.2 [-0.71, 13.18] g) CKD. Licogliflozin reduced urinary electrolytes (sodium, potassium and chloride), blood pressure and urinary volume to varying extents among different groups. Significant increases in renin (p < .05), angiotensin II (p < .05) and aldosterone (p < .01) levels were observed. Adverse events were generally mild, and most commonly included diarrhoea (94%), flatulence (68%) and abdominal pain (21%). CONCLUSION Licogliflozin treatment results in significantly increased UGE and favourable changes in urinary electrolytes and haemodynamics in patients with varying degrees of CKD (estimated glomerular filtration rate ≥ 45 mL/min/1.73 m2 ).

Abstract
PURPOSE OF REVIEW As a chronic and relapsing disease, obesity impairs metabolism and causes cardiovascular diseases. Although behavioral modification is important for the treatment of obesity, it is difficult to achieve an ideal weight or sustain the process of long-term weight loss. Therefore, the obesity control guidelines strongly recommend lifestyle interventions along with medical treatment for patients who are overweight. There is sufficient evidence supporting that pharmacotherapy in combination with behavior-based interventions can result in significant weight loss and improved cardiometabolism. RECENT FINDINGS Recent meta-analyses of new anti-obesity drugs and their weight-loss efficacy have shown that the overall placebo-subtracted weight reduction (%) for at least 12 months ranged from 2.9 to 6.8% for the following drugs: phentermine/topiramate (6.8%), liraglutide (5.4%), naltrexone/bupropion (4.0%), orlistat (2.9%), and lorcaserin (3.1%). However, very recently, on February 13, 2020, the US Food and Drug Administration (FDA) ordered the withdrawal of lorcaserin from markets, as a clinical trial to assess drug safety showed an increased risk of cancer. Currently, the anti-obesity medications that have been approved by the FDA for chronic weight management are orlistat, phentermine/topiramate, naltrexone/bupropion, and liraglutide. However, they are costly and may have adverse effects in some individuals. Therefore, drug therapy should be initiated in obese individuals after weighing its benefits and risks. One of the strategies for long-term obesity control is that anti-obesity medications should be tailored for specific patients depending on their chronic conditions, comorbidities, and preferences.

Abstract
INTRODUCTION The field of obesity medicine has evolved over the past several years. With greater understanding of its pathophysiology, obesity is regarded more as a chronic disease than a lifestyle choice. However, it is difficult to treat with lifestyle modifications alone due to the complexity of energy dysregulation. The availability of anti-obesity medications (AOMs) provides practitioners with more effective and sustainable ways to treat obesity. AREAS COVERED This review briefly summarizes the weight loss efficacy of AOMs currently approved for long-term use and expands on their therapeutic potential beyond weight loss with particular focus on obesity-related comorbidities. Possible future AOMs with promising phase II or III data are also covered. EXPERT OPINION The future of obesity medicine is in recognizing obesity as a disease and approaching treatment similarly to other chronic diseases. Lifestyle interventions alone are rarely sufficient in the treatment of chronic diseases, and pharmacotherapy often plays a necessary role in changing the course of disease. Current AOMs have proven efficacy in weight management and emerging therapeutic uses in obesity-related comorbidities, such as non-alcoholic fatty liver disease, obstructive sleep apnea, and polycystic ovarian syndrome. The development of new AOMs will further empower providers to deliver effective obesity management.

Abstract
Absorption, metabolism, and excretion (AME) of licogliflozin, a sodium-glucose co-transporters (SGLTs) 1 and 2 inhibitor, were studied in male rats, dogs, and healthy male volunteers and reported.Oral absorption of licogliflozin was rapid (tmax < 1 h) with absorption estimated at 87%, 100% and 77% in rats, dogs and humans, respectively.Excretion of licogliflozin-related radioactivity was rapid and nearly complete following oral administration with total radioactivity recovery ranging from 73% in dogs, 92.5% in humans, to 100% in rats. Dose-related radioactivity was excreted in both urine and faeces with urinary excretion playing a slightly more important role in humans (∼56%) than in animal species (∼19-41%).Elimination of licogliflozin was predominantly via metabolism with the majority of the radioactivity dose (∼54-74%) excreted as metabolites across species.The principal biotransformation pathways involved direct glucuronidation and oxidation across all species. In humans, direct glucuronidation to M17 and M27 was the major pathway observed, accounting for ∼38% of the dose in excreta while oxidative metabolism also contributed to >29% of the dose in excreta. Oxidative pathways were predominant in animal species.

Abstract
Objective The mechanisms behind the efficacy of bariatric surgery (BS) for treating obesity and type 2 diabetes, particularly with respect to the influence of the small bowel, remain poorly understood. In vitro and animal models are suboptimal with respect to their ability to replicate the human intestinal epithelium under conditions induced by obesity. Human enteroids have the potential to accelerate the development of less invasive anti-obesity therapeutics if they can recapitulate the pathophysiology of obesity. Our aim was to determine whether adult stem cell-derived enteroids preserve obesity-characteristic patient-specific abnormalities in carbohydrate absorption and metabolism. Methods We established 24 enteroid lines representing 19 lean, overweight, or morbidly obese patients, including post-BS cases. Dietary glucose absorption and gluconeogenesis in enteroids were measured. The expression of carbohydrate transporters and gluconeogenic enzymes was assessed and a pharmacological approach was used to dissect the specific contribution of each transporter or enzyme to carbohydrate absorption and metabolism, respectively. Results Four phenotypes representing the relationship between patients’ BMI and intestinal dietary sugar absorption were found, suggesting that human enteroids retain obese patient phenotype heterogeneity. Intestinal glucose absorption and gluconeogenesis were significantly elevated in enteroids from a cohort of obese patients. Elevated glucose absorption was associated with increased expression of SGLT1 and GLUT2, whereas elevated gluconeogenesis was related to increased expression of GLUT5, PEPCK1, and G6Pase. Conclusions Obesity phenotypes preserved in human enteroids provide a mechanistic link to aberrant dietary carbohydrate absorption and metabolism. Enteroids can be used as a preclinical platform to understand the pathophysiology of obesity, study the heterogeneity of obesity mechanisms, and identify novel therapeutics. Human stem cell-derived enteroids preserve the heterogeneity of obesity-related phenotypes. Four phenotypes representing the relationship between patients' BMI and intestinal dietary glucose absorption were found. Glucose absorption and gluconeogenesis were elevated in enteroids from a cohort of obese patients. Elevated glucose absorption was associated with increased expression of SGLT1 and GLUT2 in enteroids. Elevated gluconeogenesis was associated with increased expression of GLUT5, PEPCK1, and G6Pase in enteroids.

Abstract
In enterocytes, protein RS1 (RSC1A1) mediates an increase of glucose absorption after ingestion of glucose-rich food via upregulation of Na+-d-glucose cotransporter SGLT1 in the brush-border membrane (BBM). Whereas RS1 decelerates the exocytotic pathway of vesicles containing SGLT1 at low glucose levels between meals, RS1-mediated deceleration is relieved after ingestion of glucose-rich food. Regulation of SGLT1 is mediated by RS1 domain RS1-Reg, in which Gln-Ser-Pro (QSP) is effective. In contrast to QSP and RS1-Reg, Gln-Glu-Pro (QEP) and RS1-Reg with a serine to glutamate exchange in the QSP motif downregulate the abundance of SGLT1 in the BBM at high intracellular glucose concentrations by about 50%. We investigated whether oral application of QEP improves diabetes in db/db mice and affects the induction of diabetes in New Zealand obese (NZO) mice under glucolipotoxic conditions. After 6-day administration of drinking water containing 5 mM QEP to db/db mice, fasting glucose was decreased, increase of blood glucose in the oral glucose tolerance test was blunted, and insulin sensitivity was increased. When QEP was added for several days to a high fat/high carbohydrate diet that induced diabetes in NZO mice, the increase of random plasma glucose was prevented, accompanied by lower plasma insulin levels. QEP is considered a lead compound for development of new antidiabetic drugs with more rapid cellular uptake. In contrast to SGLT1 inhibitors, QEP-based drugs may be applied in combination with insulin for the treatment of type 1 and type 2 diabetes, decreasing the required insulin amount, and thereby may reduce the risk of hypoglycemia.

Abstract
Alcoholic and non-alcoholic liver diseases begin from an imbalance in lipid metabolism in hepatocytes as the earliest response. Both liver diseases share common disease features and stages (i.e., steatosis, hepatitis, cirrhosis, and hepatocellular carcinoma). However, the two diseases have differential pathogenesis and clinical symptoms. Studies have elucidated the molecular basis underlying similarities and differences in the pathogenesis of the diseases; the factors contributing to the progression of liver diseases include depletion of sulfhydryl pools, enhanced levels of reactive oxygen and nitrogen intermediates, increased sensitivity of hepatocytes to toxic cytokines, mitochondrial dysfunction, and insulin resistance. Endoplasmic reticulum (ER) stress, which is caused by the accumulation of misfolded proteins and calcium depletion, contributes to the pathogenesis, often causing catastrophic cell death. Several studies have demonstrated a mechanism by which ER stress triggers liver disease progression. Autophagy is an evolutionarily conserved process that regulates organelle turnover and cellular energy balance through decomposing damaged organelles including mitochondria, misfolded proteins, and lipid droplets. Autophagy dysregulation also exacerbates liver diseases. Thus, autophagy-related molecules can be potential therapeutic targets for liver diseases. Since ER stress and autophagy are closely linked to each other, an understanding of the molecules, gene clusters, and networks engaged in these processes would be of help to find new remedies for alcoholic and non-alcoholic liver diseases. In this review, we summarize the recent findings and perspectives in the context of the molecular pathogenesis of the liver diseases.

Abstract
Absorption of monosaccharides is mainly mediated by Na+-D-glucose cotransporter SGLT1 and the facititative transporters GLUT2 and GLUT5. SGLT1 and GLUT2 are relevant for absorption of D-glucose and D-galactose while GLUT5 is relevant for D-fructose absorption. SGLT1 and GLUT5 are constantly localized in the brush border membrane (BBM) of enterocytes, whereas GLUT2 is localized in the basolateral membrane (BLM) or the BBM plus BLM at low and high luminal D-glucose concentrations, respectively. At high luminal D-glucose, the abundance SGLT1 in the BBM is increased. Hence, D-glucose absorption at low luminal glucose is mediated via SGLT1 in the BBM and GLUT2 in the BLM whereas high-capacity D-glucose absorption at high luminal glucose is mediated by SGLT1 plus GLUT2 in the BBM and GLUT2 in the BLM. The review describes functions and regulations of SGLT1, GLUT2, and GLUT5 in the small intestine including diurnal variations and carbohydrate-dependent regulations. Also, the roles of SGLT1 and GLUT2 for secretion of enterohormones are discussed. Furthermore, diseases are described that are caused by malfunctions of small intestinal monosaccharide transporters, such as glucose-galactose malabsorption, Fanconi syndrome, and fructose intolerance. Moreover, it is reported how diabetes, small intestinal inflammation, parental nutrition, bariatric surgery, and metformin treatment affect expression of monosaccharide transporters in the small intestine. Finally, food components that decrease D-glucose absorption and drugs in development that inhibit or downregulate SGLT1 in the small intestine are compiled. Models for regulations and combined functions of glucose transporters, and for interplay between D-fructose transport and metabolism, are discussed.

Abstract
It is now widely appreciated that gastrointestinal function is central to the regulation of metabolic homeostasis. Following meal ingestion, the delivery of nutrients from the stomach into the small intestine (i.e., gastric emptying) is tightly controlled to optimise their subsequent digestion and absorption. The complex interaction of intraluminal nutrients (and other bioactive compounds, such as bile acids) with the small and large intestine induces the release of an array of gastrointestinal hormones from specialised enteroendocrine cells (EECs) distributed in various regions of the gut, which in turn to regulate gastric emptying, appetite and postprandial glucose metabolism. Stimulation of gastrointestinal hormone secretion, therefore, represents a promising strategy for the management of metabolic disorders, particularly obesity and type 2 diabetes mellitus (T2DM). That EECs are distributed distinctively between the proximal and distal gut suggests that the region of the gut exposed to intraluminal stimuli is of major relevance to the secretion profile of gastrointestinal hormones and associated metabolic responses. This review discusses the process of intestinal digestion and absorption and their impacts on the release of gastrointestinal hormones and the regulation of postprandial metabolism, with an emphasis on the differences between the proximal and distal gut, and implications for the management of obesity and T2DM.

Abstract
Non-alcoholic fatty liver disease (NAFLD) represents the most common form of chronic liver disease worldwide. Due to its association with obesity and diabetes and the fall in hepatitis C virus morbidity, cirrhosis in NAFLD is becoming the most frequent indication to liver transplantation, but the pathogenetic mechanisms are still not completely understood. The so-called gut-liver axis has gained enormous interest when data showed that its alteration can lead to NAFLD development and might favor the occurrence of non-alcoholic steatohepatitis (NASH). Moreover, several therapeutic approaches targeting the gut-pancreas-liver axis, e.g., incretins, showed promising results in NASH treatment. In this review, we describe the role of incretin hormones in NAFLD/NASH pathogenesis and treatment and how metagenomic/metabolomic alterations in the gut microbiota can lead to NASH in the presence of gut barrier modifications favoring the passage of bacteria or bacterial products in the portal circulation, i.e., bacterial translocation.

Abstract
AIMS LIK066 (licogliflozin) is a dual sodium glucose co-transporter 1/2 inhibitor with potential benefits in weight loss. This study evaluated the efficacy, tolerability and safety of licogliflozin in Japanese adults with obesity. MATERIALS AND METHODS This study was a randomized, double-blind, placebo-controlled, dose-finding study to evaluate the effect of licogliflozin (2.5, 10, 25 and 50 mg once daily) in 126 Japanese patients with obesity. The primary objective was to examine the dose-response relationship of licogliflozin treatment in body weight reduction relative to placebo at 12 weeks. The secondary objectives included assessment of responder rates, change in parameters related to complications, visceral and subcutaneous fat area, and safety during 12 weeks of treatment. RESULTS The placebo-subtracted least square mean percentage change in body weight from baseline at week 12 was -1.99 (95% confidence interval -2.92, -0.21), -3.00 (-4.15, -1.70), -3.54 (-4.54, -2.26) and - 3.91% (-5.01, -2.77) in licogliflozin 2.5, 10, 25 and 50 mg once-daily dose groups, respectively. The proportion of responders with ≥3% reduction in body weight in the licogliflozin 2.5, 10, 25 and 50 mg once-daily dose groups were 15.8%, 55.6%, 50.0% and 56.7%, respectively, versus placebo [7.1%; P ≤0.002 for all except the 2.5 mg once-daily group (P = 0.39)]. Dose-dependent reductions were observed significantly in haemoglobin A1c, uric acid, fasting plasma glucose and potentially in the waist circumference, diastolic blood pressure and visceral fat area. CONCLUSION Dual inhibition of SGLT1/2 with licogliflozin treatment induced a dose-dependent reduction in body weight in Japanese patients with obesity. Treatment with licogliflozin was safe and well tolerated in this study. The study is registered with ClinicalTrials.gov (NCT03320941).

Abstract
OBJECTIVE The aim of this study was to explore the dose response of licogliflozin, a dual inhibitor of sodium/glucose cotransporter 1 (SGLT1) and 2 (SGLT2), by evaluating change in body weight in adults with overweight or obesity. METHODS This dose-response analysis evaluated change in body weight following 24 weeks with four once-daily and twice-daily licogliflozin doses (2.5-150 mg) versus placebo (primary end point). A further 24-week analysis evaluated the efficacy and safety of two once-daily licogliflozin doses in maintaining initial weight reduction. RESULTS Licogliflozin once daily or twice daily produced a significant dose-response signal for weight loss versus placebo (P < 0.0001). However, mean adjusted percent changes in body weight after 24 weeks were modest, ranging from -0.45% to -3.83% (in the 50 mg twice daily group [95% CI: -5.26% to -2.48%]; n = 75). Responder analysis of ≥ 5% weight loss at week 24 revealed significant differences versus placebo, which were most pronounced with highest doses of 50 mg twice daily (45.3%) and 150 mg once daily (42.9%) (both P < 0.01). While weight loss was greater at higher doses, gastrointestinal adverse events were also more frequent. The 50-mg once-daily dose had perhaps the best balance between efficacy and tolerability. CONCLUSIONS Licogliflozin produced significant reductions in body weight versus placebo. However, the magnitude of weight reduction was modest.

Abstract
Treatment with licogliflozin, a dual sodium-glucose co-transporter (SGLT)1/2-inhibitor, is associated with increased stool frequency and loose stools, attributed to SGLT1 inhibition. To investigate the effect of carbohydrate content and supplements on licogliflozin-induced stools, a randomized, open-label, two-part (N = 24/part), three-period crossover study was carried out in overweight or obese adults. Significantly higher (P < 0.01) change from baseline in 3-day total number of bowel movements was observed following 3 days of licogliflozin treatment (50 mg q.d.) together with a 50% carbohydrate meal compared with a 25% and 0% carbohydrate meal. The number of stools with Bristol Stool Chart score of 6 or 7 was also significantly lower following a 0% carbohydrate meal. Supplementation with psyllium 6 g or calcium carbonate 1 g had no effect on stool changes following treatment. Licogliflozin was generally safe and well-tolerated. Loose stool associated with licogliflozin treatment and ingestion of meals can be managed by reducing the carbohydrate content of meals taken with licogliflozin.

Abstract
Clinical relevance of sodium/glucose cotransporter 2 (SGLT2) inhibitors has been rapidly evolving across several therapy areas, apart from type 2 diabetes mellitus. While some of these developments are based on recognized scientific explanations, unexpected study findings have also shaped much of our present understanding. As the role of these agents evolves in various facets of cardiology, nephrology, hepatology and endocrinology, their optimum clinical value propositions should be realized in line with the principles of personalized medicine. An updated pharmaco-ergonomic qualification tool, based on the present evidence with these agents, would be a step in this direction. This review describes the present evidence on diverse pharmacological and therapeutic aspects for various SGLT2 inhibitors, as an attempt to provide useful guidance for optimum application in clinical practice.

Effects of the dual sodium-glucose linked transporter inhibitor, licogliflozin vs placebo or empagliflozin in patients with type 2 diabetes and heart failure. Br J Clin Pharmacol 2020; 86:1346-1356. [PMID: 32068914 PMCID: PMC7318993 DOI: 10.1111/bcp.14248] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Revised: 12/23/2019] [Accepted: 01/26/2020] [Indexed: 02/06/2023] Open
Abstract
Aims Explore the efficacy, safety and tolerability of the dual sodium–glucose cotransporter (SGLT) 1 and 2 inhibitor, licogliflozin in patients with type‐2 diabetes mellitus (T2DM) and heart failure. Methods This multicentre, parallel‐group phase IIA study randomized 125 patients with T2DM and heart failure (New York Heart Association II–IV; plasma N‐terminal pro b‐type natriuretic peptide [NT‐proBNP] >300 pg/mL) to licogliflozin (2.5 mg, 10 mg, 50 mg) taken at bedtime, empagliflozin (25 mg) or placebo (44 patients completed the study). The primary endpoint was change from baseline in NT‐proBNP after 12 weeks. Secondary endpoints included change from baseline in glycated haemoglobin, fasting plasma glucose, weight, blood pressure, fasting lipid profile, high‐sensitivity c‐reactive protein, and safety and tolerability. Results Licogliflozin 10 mg for 12 weeks significantly reduced NT‐proBNP vs placebo (Geometric mean ratio 0.56 [95% confidence interval: 0.33, 0.95], P = .033). A trend was observed with 50 mg licogliflozin (0.64 [95% confidence interval: 0.40, 1.03], P = .064), with no difference between licogliflozin and empagliflozin. The largest numerical decreases in glycated haemoglobin were with licogliflozin 50 mg (−0.58 ± 0.34%) and empagliflozin (−0.44 ± 1.18%) vs placebo (−0.04 ± 0.91%). The reduction in body weight was similar with licogliflozin 50 mg (−2.15 ± 2.40 kg) and empagliflozin (−2.25 ± 1.89 kg). A numerical reduction in systolic blood pressure was seen with licogliflozin 50 mg (−9.54 ± 16.88 mmHg) and empagliflozin (−6.98 ± 15.03 mmHg) vs placebo (−2.85 ± 11.97 mmHg). Adverse events (AEs) were mild, including hypotension (6.5%), hypoglycaemia (8.1%) and inadequate diabetes control (1.6%). The incidence of diarrhoea (4.9%) was lower than previously reported. Conclusion The reduction in NT‐proBNP with licogliflozin suggests a potential benefit of SGLT1 and 2 inhibition in patients with T2DM and heart failure.

Abstract
Glucose-dependent insulinotropic polypeptide (GIP) is a gut hormone secreted from the upper small intestine, which plays an important physiological role in the control of glucose metabolism through its incretin action to enhance glucose-dependent insulin secretion. GIP has also been implicated in postprandial lipid homeostasis. GIP is secreted from enteroendocrine K-cells residing in the intestinal epithelium. K-cells sense a variety of components found in the gut lumen following food consumption, resulting in an increase in plasma GIP signal dependent on the nature and quantity of ingested nutrients. We review the evidence for an important role of sodium-coupled glucose uptake through SGLT1 for carbohydrate sensing, of free-fatty acid receptors FFAR1/FFAR4 and the monoacyl-glycerol sensing receptor GPR119 for lipid detection, of the calcium-sensing receptor CASR and GPR142 for protein sensing, and additional modulation by neurotransmitters such as somatostatin and galanin. These pathways have been identified through combinations of in vivo, in vitro and molecular approaches.

Abstract
Introduction: Obesity is compounded by a neurobiology that is resistant to weight loss. Therefore, the development of pharmacotherapies to address the pathology underlying the dysregulation of energy homeostasis is critical.Areas covered: This review examines selected clinical trial evidence for the pharmacologic treatment of obesity and provides an expert opinion on anti-obesity drug development. The article includes the outcomes of anti-obesity medications that have been evaluated in clinical trials but have not yet received approval from the U.S. Food and Drug Administration. The mechanisms of action of glucagon-like peptide-1 agonists and co-agonists, diabetes medications being investigated for weight loss, and medications acting on the central nervous system as well as peripherally are reviewed. A search was conducted on PubMed using the terms 'Obesity AND Medications' restricted to clinical trials reported in English. Using similar terms, a search was also conducted on ClinicalTrials.gov.Expert opinion: The goal of anti-obesity therapy is finding compounds that are effective and have minimal side effects. Combining medications targeting more than one of the redundant mechanisms driving obesity increases efficacy. However, targeting peripheral mechanisms to overcome the trickle-down effects of centrally acting drugs may be the key to success in treating obesity.
