Abstract
AIMS Tirzepatide is a first-in-class combination glucose-dependent insulinotropic polypeptide (GIP) receptor agonist and glucagon-like peptide 1 receptor agonist (GLP1-RA) approved for treatment of adults with type 2 diabetes mellitus (T2DM) and chronic weight management. The aim of this analysis was to assess the real-world efficacy of tirzepatide in patients with T2DM. METHODS This retrospective observational study evaluated patients with T2DM from a large urban academic medical centre who received at least 3 months of continuous tirzepatide treatment. The primary outcome was change in A1C from following tirzepatide treatment. Secondary outcomes included change in body weight and body mass index (BMI) after tirzepatide was initiated. RESULTS A total of 1896 patient charts were reviewed, and 612 patients were evaluated for the primary outcome. Over a median time period of 10.4 months, treatment with tirzepatide resulted in a mean A1C reduction of 1.02 ± 1.48% (p < 0.001). A total of 570 patients were evaluated for the secondary outcomes. Tirzepatide was associated with a mean reduction in body weight of 7.3 ± 9.3 kg (p < 0.001) and a mean reduction in BMI of 2.5 kg/m2. Greater A1C lowering and weight loss was observed in patients without prior GLP1-RA treatment compared to those switched to tirzepatide from GLP1-RA. CONCLUSIONS In a real-world population of US patients with T2DM, tirzepatide was associated with clinically and statistically significant reductions in A1C and body weight. Greater reductions in both A1C and body weight were observed among patients who were GLP1-RA naïve compared to patients switched from GLP1-RA to tirzepatide.

Abstract
Tirzepatide is a once-weekly GIP/GLP-1 receptor agonist used for treatment of type 2 diabetes (T2D) in adults and was recently approved for treatment of obesity. To determine the absorption, distribution, metabolism, and excretion (ADME) of tirzepatide, [14C]-radiolabeled tirzepatide was investigated in both humans and preclinical species. [14C]-Tirzepatide was prepared by incorporating four 14C's in the linker region between the amino acid backbone and the di-acid moiety. Healthy male participants received a single subcutaneous dose of approximately 2.9 mg tirzepatide containing approximately 100 μCi of [14C]-tirzepatide. Preclinical studies were conducted in male Sprague Dawley and Long Evans rats administered a single dose of 3 mg kg-1 (133 µCi/kg) of [14C]-tirzepatide, and male cynomolgus monkeys administered a single dose of 0.5 mg kg-1 (20 µCi/kg) of [14C]-tirzepatide. Following a single SC dose of [14C]-tirzepatide in humans, the majority of the excreted dose was recovered within 480 h. Renal excretion was identified as a principal route of elimination in all species with approximately 66 % of the administered radioactivity recovered in urine, while approximately 33 % was eliminated in feces in humans. Metabolite analysis of tirzepatide revealed the parent drug was the major circulating component in human, rat, and monkey plasma. Metabolites identified in human plasma were similar to circulating metabolites found in rats and monkeys with no circulating metabolites representing >10 % of the total radioactive drug-related exposure. Intact tirzepatide was not observed in urine or feces in any species. Tirzepatide was primarily metabolized via proteolytic cleavage of the amino acid backbone, β-oxidation of the C20 diacid moiety, and amide hydrolysis. ClinicalTrials.gov identifier: NCT 04,311,424.

Abstract
PURPOSE OF REVIEW To review the most recent clinical trials and data regarding epidemiology, pathophysiology, diagnosis, and treatment of heart failure with preserved ejection fraction with an emphasis on the recent trends in cardiometabolic interventions. RECENT FINDINGS Heart failure with preserved ejection fraction makes up approximately half of overall heart failure and is associated with significant morbidity, mortality, and overall burden on the healthcare system. It is a complex, heterogenous syndrome and clinical trials, to this point, have not revealed quite as many effective treatment options when compared to heart failure with reduced ejection fraction. Nevertheless, there is an expanding amount of data insight into the pathogenesis of this disease and the potential for newer therapies and management strategies. Heart failure with preserved ejection fraction pathology has been found to be linked to abnormal energetics, myocyte hypertrophy, cell signaling, inflammation, ischemia, and fibrosis. These mechanisms also intricately overlap with the significant comorbidities often associated with heart failure with preserved ejection fraction including, but not limited to, atrial fibrillation, chronic kidney disease, hypertension, obesity and coronary artery disease. Treatment of this disease, therefore, should focus on the management and strict regulation of these comorbidities by pharmacologic and nonpharmacologic means. In this review, a clinical update is provided reviewing the most recent clinical trials and data regarding epidemiology, pathophysiology, diagnosis, and treatment of heart failure with preserved ejection fraction with an emphasis on the recent trend in cardiometabolic interventions.

Abstract
Tirzepatide is the first ever once-weekly, injectable gastric inhibitory peptide/glucagon-like peptide 1 (GIP/GLP-1) dual agonist approved by the European Medicines Agency for type 2 diabetes. The efficacy and safety of tirzepatide have been evaluated in five global, randomized, double-blind or open-label, phase 3 studies which enrolled over 7000 people living with type 2 diabetes, across various stages of disease and with different characteristics at baseline. In this short commentary we report the salient data of the most recent trials on tirzepatide and GLP-1 receptor agonists from a clinical point of view, with the aim of highlighting similarities and mutual differences.

Abstract
INTRODUCTION Mounting evidence suggests that glucagon-like-peptide-1 receptor-agonists (GLP-1 RAs) attenuate cardiovascular-risk in type-2 diabetes (T2DM). Tirzepatide is the first-in-class, dual glucose-dependent-insulinotropic-polypeptide GIP/GLP-1 RA approved for T2DM. PATIENTS AND METHODS A systematic review and meta-analysis of randomized-controlled clinical trials (RCTs) was performed to estimate: (i) the incidence of major adverse cardiovascular events (MACE); and (ii) incidence of stroke, fatal, and nonfatal stroke in T2DM-patients treated with GLP-1 or GIP/GLP-1 RAs (vs placebo). RESULTS Thirteen RCTs (9 and 4 on GLP-1 RAs and tirzepatide, respectively) comprising 65,878 T2DM patients were included. Compared to placebo, GLP-1RAs or GIP/GLP-1 RAs reduced MACE (OR: 0.87; 95% CI: 0.81-0.94; p < 0.01; I2 = 37%), all-cause mortality (OR: 0.88; 95% CI: 0.82-0.96; p < 0.01; I2 = 21%) and cardiovascular-mortality (OR: 0.88; 95% CI: 0.80-0.96; p < 0.01; I2 = 14%), without differences between GLP-1 versus GIP/GLP-1 RAs. Additionally, GLP-1 RAs reduced the odds of stroke (OR: 0.84; 95% CI: 0.76-0.93; p < 0.01; I2 = 0%) and nonfatal stroke (OR: 0.85; 95% CI: 0.76-0.94; p < 0.01; I2 = 0%), whereas no association between fatal stroke and GLP-1RAs was uncovered (OR: 0.80; 95% CI: 0.61-1.05; p = 0.105; I2 = 0%). In secondary analyses, GLP-1 RAs prevented ischemic stroke (OR: 0.74; 95% CI: 0.61-0.91; p < 0.01; I2 = 0%) and MACE-recurrence, but not hemorrhagic stroke (OR: 0.92; 95% CI: 0.51-1.66; p = 0.792; I2 = 0%). There was no association between GLP-1RAs or GIP/GLP-1 RAs and fatal or nonfatal myocardial infarction. DISCUSSION AND CONCLUSION GLP-1 and GIP/GLP-1 RAs reduce cardiovascular-risk and mortality in T2DM. While there is solid evidence that GLP-1 RAs significantly attenuate the risk of ischemic stroke in T2DM, dedicated RCTs are needed to evaluate the efficacy of novel GIP/GLP-1 RAs for primary and secondary stroke prevention.

Tirzepatide Improved Health-Related Quality of Life Compared with Insulin Lispro in Basal Insulin-Treated Adults with Type 2 Diabetes and Inadequate Glycaemic Control: A Randomised Controlled Phase 3b Trial (SURPASS-6). Diabetes Ther 2024; 15:2039-2059. [PMID: 39008236 PMCID: PMC11330430 DOI: 10.1007/s13300-024-01620-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 07/01/2024] [Indexed: 07/16/2024] Open
Abstract
INTRODUCTION Patients with type 2 diabetes (T2D) who require intensification of basal insulin therapy need treatment options that can improve their health-related quality of life (HRQoL) and translate into better outcomes. These analyses compared patient-reported outcomes (PROs) in patients with T2D receiving tirzepatide or insulin lispro. METHODS The randomised, open-label, multinational, phase 3b SURPASS-6 trial (NCT04537923) was conducted at 135 medical research centres and hospitals in 15 countries and compared two recommended treatment intensification strategies in people with T2D and inadequate glycaemic control on basal insulin: addition of once-weekly tirzepatide versus addition of prandial insulin lispro. Randomisation was stratified by country, baseline glycated haemoglobin level and metformin use. PROs were measured using the Short Form-36 Health Survey version 2 (SF-36v2) acute form (secondary outcome), EQ-5D-5L, Ability to Perform Physical Activities of Daily Living (APPADL) questionnaire and Impact of Weight on Self-Perceptions (IW-SP) questionnaire (tertiary/exploratory outcomes). PROs were compared for the tirzepatide-pooled dose group (5, 10 and 15 mg) and each tirzepatide dose group versus insulin lispro at 52 weeks using the modified intention-to-treat efficacy analysis set. RESULTS Between 19 October 2020 and 01 November 2022, 2267 people were assessed and 1428 participants with T2D were randomised. At 52 weeks, participants in the tirzepatide-pooled group had statistically significant improved scores across all SF-36v2 domains and both component summary scores compared with insulin lispro-treated participants (p < 0.05), with the largest differences observed in the general health, vitality and mental health domains. Statistically significant improved APPADL and IW-SP total scores, as well as EQ visual analogue scale and EQ-5D-5L index scores (after adjustment for baseline scores), were observed in tirzepatide-pooled participants compared with insulin lispro-treated participants. CONCLUSIONS In adult patients with T2D and inadequate glycaemic control with basal insulin, tirzepatide treatment was associated with greater improvements in HRQoL than prandial insulin therapy in addition to clinically significant improvements in glycaemic and body weight-related parameters.

Incidence of new onset type 2 diabetes in adults living with obesity treated with tirzepatide or semaglutide: real world evidence from an international retrospective cohort study. EClinicalMedicine 2024; 75:102777. [PMID: 39246719 PMCID: PMC11377141 DOI: 10.1016/j.eclinm.2024.102777] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 07/20/2024] [Accepted: 07/22/2024] [Indexed: 09/10/2024] Open
Abstract
Background Tirzepatide, a novel dual agonist of glucagon-like-peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), has demonstrated greater magnitude of weight loss compared to semaglutide in a phase 3 clinical trial. However, the effect of tirzepatide on incidence of type 2 diabetes (T2D) in individuals with overweight and obesity, and the effect on major adverse cardiovascular outcomes in individuals with pre-existing T2D, remains unknown. Methods We performed a retrospective cohort study of anonymised electronic medical records using the TriNetX network (TriNetX LLC, Cambridge, MA, USA) a global federated database. The data used in this study was collected on 5th June 2024. Two cohorts of individuals were generated: 1) without pre-existing T2D and, 2) with T2D. We adopted an active comparator new user design on new initiations of either tirzepatide or semaglutide therapy. Analysis began from the index event which was defined as individuals on respective therapy for 6 months only. Analysis of outcomes was conducted off-drug, in individuals without a pre-existing history of the disease of interest. Individuals were followed up for 12 months post the index event. Primary outcome for cohort 1 was incidence of T2D, and for cohort 2 was composite: all-cause mortality, cerebral infarction, acute coronary syndrome, and heart failure. Secondary outcomes for cohort 1 were change in HbA1c and body weight and for cohort 2: incidence of micro- and macrovascular complications, suicidal ideation and/or attempt, and all-cause mortality. We propensity score matched (1:1) for potential confounders: baseline demographics, socioeconomic circumstances, HbA1c, weight, relevant co-morbidities, and anti-obesity, hypoglycaemic and cardioprotective agents. Findings The study population without T2D consisted of 13,846 individuals, equally split between tirzepatide and semaglutide users. Tirzepatide was associated with both lower risk for incident T2D (HR 0.73, 95% CI 0.58-0.92, p < 0.001) and greater weight loss (-7.7 kg, [95% CI -6.8, -8.5 kg], p < 0.001), compared to semaglutide (-4.8 kg, [95% CI -3.9, -5.6 kg], p < 0.001). In individuals with pre-existing T2D (n = 8446), tirzepatide was associated with lower risk of the composite outcome (HR 0.54, 95% CI 0.38-0.76, p < 0.001), cerebral infarction (HR 0.45, 95% CI 0.24-0.84, p = 0.010) and all-cause mortality (HR 0.33, 95% CI 0.15-0.73, p = 0.004) compared to semaglutide. Interpretation Tirzepatide is associated with significantly reduced risk of developing T2D and major adverse cardiovascular events in individuals living with obesity and T2D respectively. Randomised controlled trials investigating the utility of dual incretin agonists in the primary prevention of T2D and cardiovascular disease in higher risk populations are now required. Funding Nil.

Abstract
In this systematic review and meta-analysis, we compared the efficacy and safety of tirzepatide with those of long-acting or ultra-long-acting insulin for type 2 diabetes. PubMed, Web of Science, Scopus, and Google Scholar were searched from the inception to August 20, 2023. All clinical trials or randomized clinical trials comparing the efficacy of tirzepatide with long-acting or ultra-long-acting insulin for treating type 2 diabetes were included. Three randomized clinical trials, namely SURPASS-3, SURPASS-4, and SURPASS-AP-Combo, with 4339 patients were included. Compared with daily insulin glargine and degludec, once-weekly tirzepatide significantly decreased HbA1c (WMD -1.08%, 95% CI (-1.37, -0.78)), 2h-posprandial blood sugar (BS) (WMD -28.19 mg/dL, 95% CI (-44.98, -11.41)), pre-meal BS (WMD -11.86 mg/dL, 95% CI (-22.83, -0.9)), body weight (WMD -10.61 kg, 95% CI (-13.24, -7.97)), systolic blood pressure (WMD -6.47 mmHg, 95% CI (-8.32, -4.61)), diastolic blood pressure (WMD -2.30 mmHg, 95% CI (-3.05, -1.55)), total cholesterol (WMD -4.78%, 95% CI (-7.05, -2.50)), triglyceride (WMD -14.49%, 95% CI (-19.55, -9.43)), LDL cholesterol (WMD -5.98%, 95% CI (-9.83, -2.13)), and VLDL cholesterol (WMD -14.18%, 95% CI (-19.03, -9.33)) and increased HDL cholesterol (WMD 7.13%, 95% CI (-9.83, -2.13)), with a lower risk of hypoglycemia defined as BS ≤ 70 mg/dL (RR 0.46, 95% CI (0.28, 0.75)). All doses of once-weekly tirzepatide (5 mg, 10 mg, and 15 mg) were superior or non-inferior to insulin. Once-weekly tirzepatide can be a substitution for long-acting insulin in type 2 diabetes with a greater efficacy.

Abstract
INTRODUCTION Incretin-based therapies have emerged as effective treatments for type 2 diabetes (T2D) and obesity. However, not all patients achieve optimal outcomes with existing treatments, highlighting the need for more effective solutions. AREAS COVERED We present a comprehensive evaluation of Tirzepatide (TZP), a novel dual glucose-dependent insulinotropic polypeptide/glucagon-like peptide-1 (GIP/GLP-1) receptor agonist, for managing obesity and T2D. We conducted a systematic search of Cochrane, PubMed, Scopus, and Web of Science databases from inception to April 2024. The focus of the review is on the development and therapeutic potential of TZP, with detailed exploration on pharmacodynamics, pharmacokinetics, clinical efficacy, and safety. Furthermore, it reviews TZP's impacts on glycemic control, weight management, and its potential cardiovascular (CV) benefits. EXPERT OPINION TZP represents a significant advancement in the dual-targeted approach to treating T2D and obesity. Its unique mechanism of action offers superior efficacy in reducing glycemic levels and body weight compared to existing therapies. New data suggesting improvements in CV outcomes indicate that TZP could set a new standard in the treatment paradigm. While long-term data on efficacy and safety are still forthcoming, current evidence positions TZP as a promising option for patients who have not reached their therapeutic goals with existing treatments.

Abstract
Glucagon-like peptide-1 receptor agonist (GLP-1RA) medications have been shown to be effective in achieving optimal glucose control and reducing all-cause death, cardiovascular death, nonfatal myocardial infarction, hospitalization for heart failure, and end-stage kidney disease in individuals with type 1 (T1D) and type 2 diabetes (T2D). However, use of these medications has been associated with increased hypoglycaemia risk in patients treated with concomitant antihyperglycaemic medications. The risk is particularly high in patients with T1D due to their loss of glucagon counter-regulatory response. This article reviews the effect of GLP-1RA formulations on the development of hypoglycaemia in individuals with T1D and T2D treated with insulin therapy, discusses the benefits of continuous glucose monitoring with GLP-1RA treatment, and presents strategies for safely initiating GLP-1RA therapy in these individuals.

Abstract
Tirzepatide, a novel GLP-1/GIP dual receptor agonist, shows significant advantages in glycemic management and weight control. By summarizing the results of the SURMOUNT and SURPASS clinical trials, we evaluate the efficacy and safety of tirzepatide in reducing blood glucose and weight. These trials indicate that tirzepatide significantly lowers HbA1c levels (with a maximum reduction of 2.24%) and promotes weight loss (up to 11.2 kg) with good tolerability. However, there are still some challenges in its clinical application, including high treatment costs and gastrointestinal discomfort. Additionally, the safety and efficacy of tirzepatide in special populations, such as patients with renal impairment, require further investigation. Future large-scale clinical trials, such as SURPASS-CVOT and SUMMIT, are expected to further verify the long-term benefits of tirzepatide in cardiovascular health management, providing stronger evidence for its comprehensive treatment of diabetes and its complications.

[PMID: 39192522 DOI: 10.1111/dom.15887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 08/04/2024] [Accepted: 08/05/2024] [Indexed: 08/29/2024]
Abstract
AIM Normoglycaemia was achieved in a significant proportion of Japanese participants with type 2 diabetes in two phase 3 studies of tirzepatide. This post hoc exploratory analysis aimed to identify predictive factors associated with normoglycaemia achievement. MATERIALS AND METHODS SURPASS J-mono and SURPASS J-combo study data were pooled for this analysis. Characteristics of participants in whom normoglycaemia [glycated haemoglobin (HbA1c) <5.7%] was achieved were summarized. Logistic regression analyses were performed with HbA1c <5.7% achievement as the target variable. RESULTS Of 912 participants, normoglycaemia was achieved in 553 (60.6%) following 52 weeks of tirzepatide treatment. Overall, the mean (SD) age was 56.7 (10.6) years and mean diabetes duration was 7.7 (6.0) years, and 76% of participants were men. Mean (SD) change from baseline in HbA1c and bodyweight was -2.87% (0.95) versus -2.47% (1.1) and -10.30 (5.8) kg versus -3.75 (4.3) kg for participants in whom normoglycaemia was and was not reached, respectively. Multivariate regression analyses showed that lower baseline body mass index, shorter disease duration and lower baseline HbA1c were significantly associated with higher rates of normoglycaemia achievement (p = 0.009, p = 0.008, p < 0.001, respectively) as was a tirzepatide dose of 10 or 15 mg compared with 5 mg (p < 0.001). The highest percentage of participants in whom normoglycaemia (94%) was achieved were those with lower baseline HbA1c (<8%) and the greatest weight reduction (≥15%). CONCLUSIONS Baseline HbA1c and body mass index, disease duration and the tirzepatide treatment group were shown to be predictive factors for achieving normoglycaemia. A lower baseline HbA1c was most strongly associated with normoglycaemia achievement.

Abstract
INTRODUCTION Tirzepatide is a novel once-week dual GIP/GLP-1 RA agonist approved for T2DM and its role to reduce cardiovascular events remains to be elucidated. The goal of this trial is to assess how tirzepatide affects the progression of atherosclerotic plaque as determined by multidetector computed tomography angiography (MDCTA). METHODS This trial is a double blind, randomized, prospective, placebo-controlled multi-center phase IV trial. Participant eligible for the study will be adults with T2DM between 40 and 80 years of age who have HbA1c ≥7.0% to ≤10.5% and at least 20% stenosis in major epicardial vessel on CCTA. Baseline examination will include the results of their demographics, lab tests, coronary calcium, as well as coronary plaque volume/composition. Following randomization, tirzepatide or placebo will be given at a weekly dose of 2.5 mg, and a fixed dose-escalation strategy will be followed. Patients will undergo quarterly visits for safety assessments and labs, and follow up with repeat CCTA at 1 year. DISCUSSION This study evaluates the anti-atherogenic potential of tirzepatide, providing a mechanism of potential CV benefit. This is crucial to our understanding of T2DM treatment and CVD since plaque progression portends worse outcomes in these populations. MDCTA is a noninvasive method that assesses the volume, composition, and degree of coronary vessel stenosis. CONCLUSION This study will be the first study to assess the effects of tirzepatide on atherosclerotic plaque progression measured by MDCTA in participants with T2DM.

Abstract
Background Many studies have explored the risk factors associated with cognitive impairment in patients with Type 2 diabetes mellitus (T2DM). However, research on determining the optimal threshold for these risk factors and comparative studies on the therapeutic effects of insulin and metformin is limited. This study aims to establish the optimal threshold for cognitive impairment risk factors in T2DM patients and compare the efficacy of insulin and metformin in treating mild cognitive impairment (MCI). Methods A total of 308 patients with T2DM were included. The optimal threshold for cognitive impairment risk factors was determined using receiver operating characteristic curve and binary logistic regression models. MCI patients were divided into three groups: insulin, metformin, and insulin with metformin. The treatment effect was evaluated after a 6-month follow-up. Results The study identified several factors that influenced cognitive function in T2DM patients, including female gender, duration of diabetes >13.50 years, years of education >7.50 years, and serum sodium level > 141.90 mmol/L. Metformin and insulin with metformin showed superior therapeutic effects compared to insulin alone, but no difference was observed between metformin and combination therapy. Conclusion Special attention should be given to female and those with diabetes duration >13.50 years, as well as to individuals with educational level ≤ 7.50 years and serum sodium concentration ≤ 141.90 mmol/L. Metformin and insulin with metformin effectively improve MCI in patients with T2DM and outperform insulin monotherapy. The efficacy of metformin and combination therapy was found to be comparable.

Abstract
PURPOSE Randomized controlled trials with tirzepatide (TZP) displayed unprecedented glucose and body weight lowering efficacy in individuals with type 2 diabetes and/or obesity and a safety profile similar to that of glucagon-like peptide-1 receptor agonists (GLP-1RA), mainly characterized by gastrointestinal (GI) adverse events (AE). Concerns on diabetic retinopathy, pancreato-biliary disorders, and medullary thyroid cancer were also addressed. We aimed to investigate whether the same safety issues emerged from the FDA Adverse Event Reporting System (FAERS) post-marketing surveillance database. METHODS OpenVigil 2.1-MedDRA-v24 and AERSMine (data 2004Q1-2023Q3) were used to query the FAERS database. Reports of GI AE, diabetic retinopathy, pancreato-biliary disorders, and medullary thyroid cancer were investigated. The analysis was then filtered for age, gender, and designation as primary suspect. AE occurrence with TZP was compared to insulin, sodium-glucose cotransporter-2 inhibitors, metformin, and GLP-1RA. RESULTS Disproportionate reporting of GI [i.e., nausea (ROR 4.01, 95% CI 3.85-4.19)] and pancreato-biliary disorders [i.e., pancreatitis (ROR 3.63, 95% CI 3.15-4.19)], diabetic retinopathy (ROR 4.14, 95% CI 2.34-7.30), and medullary thyroid cancer (ROR 13.67, 95% CI 4.35-42.96) was detected. TZP exhibited a similar risk of GI AE and medullary thyroid cancer and a lower risk of most pancreato-biliary AE and diabetic retinopathy vs. GLP-1RA. CONCLUSIONS TZP was associated with an increased risk of specific AE. However, its safety profile was similar to that of GLP-1RA, without increased risk of pancreato-biliary AE, diabetic retinopathy, and medullary thyroid cancer.

Abstract
Among newer classes of drugs for type 2 diabetes mellitus (T2DM), glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are incretin-based agents that lower both blood sugar levels and promote weight loss. They do so by activating pancreatic GLP-1 receptors (GLP-1R) to promote glucose-dependent insulin release and inhibit glucagon secretion. They also act on receptors in the brain and gastrointestinal tract to suppress appetite, slow gastric emptying, and delay glucose absorption. Phase 3 clinical trials have shown that GLP-1 RAs improve cardiovascular outcomes in the setting of T2DM or overweight/obesity in people who have, or are at high risk of having atherosclerotic cardiovascular disease. This is largely driven by reductions in ischemic events, although emerging evidence also supports benefits in other cardiovascular conditions, such as heart failure with preserved ejection fraction. The success of GLP-1 RAs has also seen the evolution of other incretin therapies. Tirzepatide has emerged as a dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA, with more striking effects on glycemic control and weight reduction than those achieved by isolated GLP-1R agonism alone. This consists of lowering glycated hemoglobin levels by more than 2% and weight loss exceeding 15% from baseline. Here, we review the pharmacological properties of GLP-1 RAs and tirzepatide and discuss their clinical effectiveness for T2DM and overweight/obesity, including their ability to reduce adverse cardiovascular outcomes. We also delve into the mechanistic basis for these cardioprotective effects and consider the next steps in implementing existing and future incretin-based therapies for the broader management of cardiometabolic disease.

Abstract
Individuals with excessive adipose tissue and type 2 diabetes mellitus (T2DM) face a heightened risk of cardiovascular morbidity and mortality. Metabolic surgery is an effective therapy for people with severe obesity to achieve significant weight loss. Additionally, metabolic surgery improves blood glucose levels and can lead to T2DM remission, reducing major adverse cardiovascular outcomes (MACE). Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RAs) are a class of medication that effectively reduce body weight and MACE in patients with T2DM. This review explores the potential mechanisms underlying the cardioprotective benefits of metabolic surgery and GLP-1RA-based therapies and discusses recent evidence and emerging therapies in this dynamic area of research.

Abstract
OBJECTIVE This prospective study aimed to describe the clinical course in terms of glycemic outcomes, body weight, and adverse events during the first 12 weeks following a switch from glucagon-like peptide-1 receptor agonists (GLP-1 RAs) directly to tirzepatide 5 mg. METHODS Participants were ≥18 years with type 2 diabetes (T2D), glycated hemoglobin (HbA1c) ≥6.5% to ≤9.0%, body mass index ≥25 kg/m2 and were on a stable treatment dose of GLP-1 RAs (liraglutide every day [1.2, 1.8 mg], semaglutide once-weekly [0.5, 1.0, 2.0 mg], or dulaglutide once-weekly [0.75, 1.5, 3.0, and 4.5 mg]) for ≥3 months at baseline. The primary end point was HbA1c change from baseline at week 12. Secondary end points included change from baseline in fasting serum glucose, body weight, and glucose assessed by continuous glucose monitoring. Safety was also assessed. RESULTS Participants were 58.3 years on average, with baseline HbA1c 7.39%, body mass index 35.18 kg/m2, T2D duration around 12.4 years, and included 55% females. Semaglutide (55%) and dulaglutide (42%) were the most commonly used GLP-1 RAs at baseline with semaglutide 1.0 mg and dulaglutide 1.5 mg being the most common treatment doses. At week 12, mean HbA1c changed from baseline by -0.43%, fasting serum glucose by -7.83 mg/dL, and body weight by -2.15 kg (all P < .01). Glycemic outcomes and body weight improved in participants in all baseline GLP-1 RA subgroups. Twenty participants (13.2%) developed gastrointestinal events. Three (2%) participants discontinued tirzepatide due to adverse events. There were no severe hypoglycemic events or deaths. CONCLUSION In this prospective study, when people with T2D on stable GLP-1 RA treatment were switched directly to tirzepatide 5 mg, they experienced improved glycemic outcomes and additional weight reduction with an acceptable risk of adverse gastrointestinal events over 12 weeks.

GLP1-GIP receptor co-agonists: a promising evolution in the treatment of type 2 diabetes. Acta Diabetol 2024; 61:941-950. [PMID: 38831203 PMCID: PMC11329401 DOI: 10.1007/s00592-024-02300-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Accepted: 05/04/2024] [Indexed: 06/05/2024]
Abstract
Type 2 diabetes represents a growing challenge for global public health. Its prevalence is increasing worldwide, and, like obesity, it affects progressively younger populations compared to the past, with potentially greater impact on chronic complications. Dual glucagon like peptide 1 (GLP1) and glucose-dependent insulinotropic peptide (GIP) receptor agonists are among the new pharmacological strategies recently developed to address this challenge. Tirzepatide, characterized by its ability to selectively bind and activate receptors for the intestinal hormones GIP and GLP-1, has been tested in numerous clinical studies and is already currently authorized in several countries for the treatment of type 2 diabetes and obesity. In this context, the aim of the present document is to summarize, in the form of a narrative literature review, the currently available data on the main mechanisms of action of GIP/GLP-1 co-agonists and the clinical effects of tirzepatide evaluated in various clinical trials.

Abstract
Obesity and type 2 diabetes mellitus (T2DM) are widespread, non-communicable diseases that are responsible for considerable levels of morbidity and mortality globally, primarily in the form of cardiovascular disease (CVD). Changes to lifestyle and behaviour have insufficient long-term efficacy in most patients with these diseases; metabolic surgery, although effective, is not practically deliverable on the scale that is required. Over the past two decades, therapies based on incretin hormones, spearheaded by glucagon-like peptide 1 (GLP1) receptor agonists (GLP1RAs), have become the treatment of choice for obesity and T2DM, and clinical evidence now suggests that these agents have benefits for CVD. We review the latest advances in incretin-based pharmacotherapy. These include 'GLP1 plus' agents, which combine the known advantages of GLP1RAs with the activity of additional hormones, such as glucose-dependent insulinotropic peptide, glucagon and amylin, to achieve desired therapeutic goals. Second-generation non-peptidic oral GLP1RAs promise to extend the benefits of GLP1 therapy to those who do not want, or cannot have, subcutaneous injection therapy. We conclude with a discussion of the knowledge gaps that must be addressed before incretin-based therapies can be properly deployed for maximum benefit in the treatment of obesity and T2DM.

Abstract
Obesity, a global health challenge, necessitates innovative approaches for effective management. Targeting gut peptides in the development of anti-obesity pharmaceuticals has already demonstrated significant efficacy. Ghrelin, peptide YY (PYY), cholecystokinin (CCK), and amylin are crucial in appetite regulation offering promising targets for pharmacological interventions in obesity treatment using both peptide-based and small molecule-based pharmaceuticals. Ghrelin, a sole orexigenic gut peptide, has a potential for anti-obesity therapies through various approaches, including endogenous ghrelin neutralization, ghrelin receptor antagonists, ghrelin O-acyltransferase, and functional inhibitors. Anorexigenic gut peptides, peptide YY, cholecystokinin, and amylin, have exhibited appetite-reducing effects in animal models and humans. Overcoming substantial obstacles is imperative for translating these findings into clinically effective pharmaceuticals. Peptide YY and cholecystokinin analogues, characterized by prolonged half-life and resistance to proteolytic enzymes, present viable options. Positive allosteric modulators emerge as a novel approach for modulating the cholecystokinin pathway. Amylin is currently the most promising, with both amylin analogues and dual amylin and calcitonin receptor agonists (DACRAs) progressing to advanced stages of clinical trials. Despite persistent challenges, innovative pharmaceutical strategies provide a glimpse into the future of anti-obesity therapies.

Abstract
AIM Tirzepatide is a glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 (GLP-1) dual receptor agonist (RA) that reduces glycated haemoglobin (HbA1c) and weight in patients with type 2 diabetes. We assessed the effectiveness of tirzepatide in real-world use in an Arab population. METHODS Review of clinical data from a specialist outpatient diabetes centre; study time points and outcome measures were pre-specified. RESULTS Tirzepatide was initiated in 8945 patients between 24 October 2022 and 31 December 2023. Of these, 3686 individuals reached 40 weeks of follow-up. At initiation, the mean ± SD age was 54.1 ± 11.5 years, body mass index 34.6 ± 6.0 kg/m2 and HbA1c 7.3 ± 1.5% (56 ± 17 mmol/mol); 2296 (62%) were switched to tirzepatide from another GLP-RA and 317 (8.6%) reported previous bariatric surgery. The maximum dose dispensed was ≥12.5 mg/week in 1087, 7.5-10.0 mg/week in 1688 and 2.5-5.0 mg/week in 911. The mean 40-week reduction in HbA1c was 0.6 ± 1.2% (8 ± 13 mmol/mol) and the reduction in weight was 4.5 ± 6.9 kg (4.8 ± 7.3%). GLP-RA-naïve patients experienced a significantly greater reduction in HbA1c [1.0 ± 1.3% (11 ± 14 mmol/mol) versus 0.5 ± 1.2% (6 ± 13 mmol/mol), p < .0001] and weight (7.2 ± 8.6 vs. 4.2 ± 6.6 kg, p < .0001) compared with previously exposed individuals. Post-metabolic bariatric surgery patients lost significantly more weight (7.8 ± 9.4 vs. 4.5 ± 7.0 kg, p < .0001). Improvements in blood pressure, lipid profile, and liver transaminases were noted at 40 weeks. Tirzepatide was well tolerated, with 288 (7.8%) of patients discontinuing treatment because of adverse effects, predominantly gastrointestinal. CONCLUSION In real-world use, tirzepatide significantly reduced HbA1c levels and weight and was well tolerated. Previous GLP-RA use was associated with significantly lesser HbA1c and weight reduction, and previous metabolic bariatric surgery was associated with greater weight loss.

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.

Abstract
OBJECTIVE This study was conducted to investigate the effects of glucagon-like peptide-1 receptor (GLP-1) agonists on the lipid profiles of patients with type 2 diabetes. METHODS We retrieved the data of phase 3 randomized controlled trials on GLP-1 agonists in patients with type 2 diabetes from the PubMed, Embase, and Cochrane library up to 11 February 2024. We extracted % changes in low-density lipoprotein cholesterol (LDL-C)/high-density lipoprotein cholesterol/total cholesterol (T-CHO) and triglycerides levels from baseline. Using Bayesian network meta-analysis, mean differences and 95% credible intervals for lipid changes were estimated as a unit of percentage points (%p) by class. RESULTS Twenty-six studies covering 22,290 participants were included. The glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 dual agonist showed significant differences in LDL-C (range of mean differences: -11.61 to -6.77%p), triglycerides (-19.94 to -13.31%p), and T-CHO (-7.94 to -5.09%p) levels compared to placebo, insulin, and sodium-glucose co-transporter 2 (SGLT2) inhibitors. The GLP-1 agonist significantly reduced T-CHO (-5.20%p; -6.39%p) and LDL-C (-4.32%p; -8.17%p) levels compared to placebo and SGLT2 inhibitors, respectively. CONCLUSIONS The GIP/GLP-1 dual agonist positively affects the lipid profiles of patients with type 2 diabetes. This may contribute to a lower risk of cardiovascular disease in patients with type 2 diabetes. PROTOCOL REGISTRATION PROSPERO (CRD42021282668).

Abstract
PURPOSE OF REVIEW Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are gaining importance due to their effects on cardiovascular parameters. This review discusses the findings of dedicated cardiovascular outcome trials of GLP-1RAs and summarizes their utility to help clinicians understand their role in cardiovascular disease. RECENT FINDINGS Patients with diabetes mellitus are at an increased risk of cardiovascular disease. Cardiovascular outcome trials have shown GLP-1RAs decrease the primary composite outcome of the first occurrence of major adverse cardiovascular events (MACE) in patients with diabetes. Additionally, select GLP-1RAs have also shown improved cardiovascular outcomes in patients without diabetes who are either overweight (BMI ≥ 27), or obese (BMI ≥ 30). There have also been encouraging results in patients with heart failure with preserved ejection fraction. There is increasing evidence showing GLP-1RAs are beneficial across the cardiometabolic spectrum of disease. Implementation of these therapeutics into clinical practice is important to improve cardiovascular risk.

Abstract
INTRODRODUCTION Obesity and its associated metabolic conditions have become a significant global health problem in recent years, with many people living with obesity fulfilling criteria for pharmacological treatment. The development of the glucagon-like peptide-1 receptor agonists for chronic weight management has triggered new interest in the incretins and other hormones as targets for obesity, and investigations into dual and triple co-agonists. METHODS The objective of this narrative review was to summarize the available data on approved and emerging incretin-based agents for the treatment of obesity. RESULTS In clinical trials of currently available agents in people with overweight or obesity, weight loss of between 6% and 21% of baseline body weight has been observed, with between 23% and 94% of participants achieving 10% or higher weight loss, depending on the study and the agent used. Favourable outcomes have also been seen with regard to cardiovascular risk and outcomes, diabetes prevention, metabolic dysfunction-associated steatotic liver disease/steatohepatitis and prevention of weight regain after metabolic surgery. Limitations associated with these agents include high costs, the potential for weight regain once treatment is stopped, the potential loss of lean body mass and gastrointestinal adverse events; potential issues with respect to gallbladder and biliary diseases require further investigation. CONCLUSIONS Many dual and triple co-agonists are still in development, and more data are needed to assess the efficacy, safety and tolerability of these emerging therapies versus the established incretin-based therapies; however, data are promising, and further results are eagerly awaited.

Abstract
For more than a century, physicians have searched for ways to pharmacologically reduce excess body fat. The tide has finally turned with recent advances in biochemically engineered agonists for the receptor of glucagon-like peptide-1 (GLP-1) and their use in GLP-1-based polyagonists. These polyagonists reduce body weight through complementary pharmacology by incorporating the receptors for glucagon and/or the glucose-dependent insulinotropic polypeptide (GIP). In their most advanced forms, gut-hormone polyagonists achieve an unprecedented weight reduction of up to ∼20%-30%, offering a pharmacological alternative to bariatric surgery. Along with favorable effects on glycemia, fatty liver, and kidney disease, they also offer beneficial effects on the cardiovascular system and adipose tissue. These new interventions, therefore, hold great promise for the future of anti-obesity medications.

RESEARCH DESIGN AND METHODS A retrospective analysis of adverse events (AEs) reports associated with tirzepatide was conducted from the second quarter of 2022 through the fourth quarter of 2023, utilizing the FDA Adverse Event Reporting System (FAERS) database. Signal mining utilized the reporting odds ratio (ROR) method, and onset time was analyzed utilizing the Weibull Shape Parameter (WSP). RESULTS We identified 25,215 AE reports related to tirzepatide, predominantly in the 65 to 85 age group. Four positive signals were found at the system organ classes level. Additionally,109 AEs at the preferred terms level with positive signals were indicated. Included among these are novel signals, such as the presence of thyroid mass, medullary thyroid carcinoma, and conditions affecting the reproductive system and breast. Most AEs occurred within the first 30 days. The WSP was 0.66, indicating a propensity for early failure type. CONCLUSIONS This study identified several novel AE signals for tirzepatide, highlighting the need for careful monitoring, especially in the early stages of treatment.

Bridging the gap between GLP1-receptor agonists and cardiovascular outcomes: evidence for the role of tirzepatide. Cardiovasc Diabetol 2024; 23:242. [PMID: 38987789 PMCID: PMC11238498 DOI: 10.1186/s12933-024-02319-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2024] [Accepted: 06/16/2024] [Indexed: 07/12/2024] Open
Abstract
Tirzepatide is a new drug targeting glucagon-like peptide 1(GLP1) and gastric inhibitory polypeptide (GIP) receptors. This drug has demonstrated great potential in improving the clinical outcomes of patients with type 2 diabetes. It can lead to weight loss, better glycemic control, and reduced cardiometabolic risk factors. GLP1 receptor agonists have been proven effective antidiabetic medications with possible cardiovascular benefits. Even though they have been proven to reduce the risk of major adverse cardiovascular events, their effectiveness in treating heart failure is unknown. Unlike traditional GLP1 receptor agonists, tirzepatide is more selective for the GIP receptor, resulting in a more balanced activation of these receptors. This review article discusses the possible mechanisms tirzepatide may use to improve cardiovascular health. That includes the anti-inflammatory effect, the ability to reduce cell death and promote autophagy, and also its indirect effects through blood pressure, obesity, and glucose/lipid metabolism. Additionally, tirzepatide may benefit atherosclerosis and lower the risk of major adverse cardiac events. Currently, clinical trials are underway to evaluate the safety and efficacy of tirzepatide in patients with heart failure. Overall, tirzepatide's dual agonism of GLP1 and GIP receptors appears to provide encouraging cardiovascular benefits beyond glycemic control, offering a potential new therapeutic option for treating cardiovascular diseases and heart failure.

Abstract
Tirzepatide is a novel antidiabetic medication a single-molecule, agonist to the glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors. It is approved in the USA and EU for the treatment of type 2 diabetes mellitus (T2DM) and obesity. Due to the potential novelty represented by incorporating tirzepatide to clinical practice, we aim to review practical aspects of tirzepatide use in T2DM and the supporting scientific evidence. A group of ten endocrinologists involved as investigators in the phase 3 SURPASS clinical trial program followed a nominal group technique, a qualitative research methodology designed as a semi-structured group discussion to reach a consensus on the selection of a set of practical aspects. The scientific evidence for tirzepatide has been reviewed with respect to a number of patients' clinical profiles and care goals. Information of interest related to adverse events, special warnings and precautions, and other considerations for tirzepatide use has been included. Finally, information provided to the patients has been summarized. The practical aspects reported herein may be helpful in guiding physicians in the use of tirzepatide and contribute to optimizing the management of T2DM.

Abstract
BACKGROUND The use of histological inclusion criteria for clinical trials of at-risk metabolic dysfunction-associated steatohepatitis (MASH) is often associated with high screen failure rates. AIMS To describe the design of a trial investigating tirzepatide treatment of MASH and to examine the effect of new inclusion criteria incorporating the use of the FibroScan-AST (FAST) score on the proportion of patients meeting histological criteria. METHODS SYNERGY-NASH is a Phase 2b, multicentre, randomised, double-blinded, placebo-controlled trial in patients with biopsy-confirmed MASH, F2-F3 fibrosis and NAFLD Activity Score ≥4. New inclusion criteria (FAST score >0.35 and an increase in AST inclusion criterion from >20 to >23 U/L) were adopted during the trial, allowing us to examine its impact on the qualification rate. RESULTS 1583 participants were screened, 651 participants proceeded to liver biopsy and 190 participants were randomised with an overall screen fail rate of 87%. Following the protocol amendment, the overall qualification rate for per-protocol biopsies was minimally changed from 27.5% to 28.9% with considerable variation among different investigator medical speciality types: endocrinology: from 37.5% to 39.3%; gastroenterology/hepatology: from 26.0% to 23.3%; other specialities: from 21.3% to 29.7%. At 29 sites that performed per-protocol biopsies before and after the amendment, qualification rates changed as follows: all: 26.1% to 29.1%; endocrinology: from 35.0% to 40.9%; gastroenterology/hepatology: 25.6% to 20.0%; other specialities: from 16.1% to 27.8%. CONCLUSIONS For at-risk MASH trials based on liver histology, the implementation of inclusion criteria with the proposed FAST score and AST cut-offs in this trial was most effective at non-specialist sites.

Abstract
AIMS To investigate effects of tirzepatide, a dual receptor agonist for glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 (GLP-1), on eating behaviors. METHODS Eating behaviors were evaluated by using a validated questionnaire survey in 33 Japanese patients with type 2 diabetes mellitus (T2DM) (mean age: 51.8 years) who were treated with tirzepatide (2.5 mg/week for 4 weeks and then 5.0 mg/week) for 6 months (M). RESULTS Treatment with tirzepatide significantly decreased median hemoglobin A1c (HbA1c) (baseline/3 M/6 M: 7.3 %/6.0 %/5.8 %), mean body weight (BW) (baseline/3 M/6 M: 87.7 kg/82.0 kg/79.6 kg) and mean relative score of eating behaviors (baseline/3 M/6 M: 57.0/50.7/45.9). In the GLP-1 receptor agonist (GLP-1RA) naïve group (n = 20, men/women: 13/7), HbA1c and BW were continuously decreased up to 6 M. Changes in eating behaviors were mainly observed in the first 3 M. In the GLP-1RA non-naïve group (n = 13, men/women: 8/5), reductions in HbA1c and BW were predominant in the first 3 M, and changes in eating behaviors were observed up to 6 M. There were no significant correlations of changes in scores of eating behaviors with changes in glycemic control or those in BW. CONCLUSIONS Tirzepatide ameliorates eating behaviors as well as glycemic management and obesity in Japanese patients with T2DM, and the patterns of improvement are partially dependent on prior exposure to GLP-1RAs.

Abstract
AIMS/HYPOTHESIS We conducted a systematic review and network meta-analysis to compare the efficacy and safety of s.c. administered tirzepatide vs s.c. administered semaglutide for adults of both sexes with type 2 diabetes mellitus. METHODS We searched PubMed and Cochrane up to 11 November 2023 for RCTs with an intervention duration of at least 12 weeks assessing s.c. tirzepatide at maintenance doses of 5 mg, 10 mg or 15 mg once weekly, or s.c. semaglutide at maintenance doses of 0.5 mg, 1.0 mg or 2.0 mg once weekly, in adults with type 2 diabetes, regardless of background glucose-lowering treatment. Eligible trials compared any of the specified doses of tirzepatide and semaglutide against each other, placebo or other glucose-lowering drugs. Primary outcomes were changes in HbA1c and body weight from baseline. Secondary outcomes were achievement of HbA1c target of ≤48 mmol/mol (≤6.5%) or <53 mmol/mol (<7.0%), body weight loss of at least 10%, and safety outcomes including gastrointestinal adverse events and severe hypoglycaemia. We used version 2 of the Cochrane risk-of-bias tool (ROB 2) to assess the risk of bias, conducted frequentist random-effects network meta-analyses and evaluated confidence in effect estimates utilising the Confidence In Network Meta-Analysis (CINeMA) framework. RESULTS A total of 28 trials with 23,622 participants (44.2% female) were included. Compared with placebo, tirzepatide 15 mg was the most efficacious treatment in reducing HbA1c (mean difference -21.61 mmol/mol [-1.96%]) followed by tirzepatide 10 mg (-20.19 mmol/mol [-1.84%]), semaglutide 2.0 mg (-17.74 mmol/mol [-1.59%]), tirzepatide 5 mg (-17.60 mmol/mol [-1.60%]), semaglutide 1.0 mg (-15.25 mmol/mol [-1.39%]) and semaglutide 0.5 mg (-12.00 mmol/mol [-1.09%]). In between-drug comparisons, all tirzepatide doses were comparable with semaglutide 2.0 mg and superior to semaglutide 1.0 mg and 0.5 mg. Compared with placebo, tirzepatide was more efficacious than semaglutide for reducing body weight, with reductions ranging from 9.57 kg (tirzepatide 15 mg) to 5.27 kg (tirzepatide 5 mg). Semaglutide had a less pronounced effect, with reductions ranging from 4.97 kg (semaglutide 2.0 mg) to 2.52 kg (semaglutide 0.5 mg). In between-drug comparisons, tirzepatide 15 mg, 10 mg and 5 mg demonstrated greater efficacy than semaglutide 2.0 mg, 1.0 mg and 0.5 mg, respectively. Both drugs increased incidence of gastrointestinal adverse events compared with placebo, while neither tirzepatide nor semaglutide increased the risk of serious adverse events or severe hypoglycaemia. CONCLUSIONS/INTERPRETATION Our data show that s.c. tirzepatide had a more pronounced effect on HbA1c and weight reduction compared with s.c. semaglutide in people with type 2 diabetes. Both drugs, particularly higher doses of tirzepatide, increased gastrointestinal adverse events. REGISTRATION PROSPERO registration no. CRD42022382594.

Abstract
Despite the risk of atherosclerosis has progressively declined over the past few decades, subjects with type 2 diabetes mellitus (T2DM) continue to experience substantial excess of atherosclerotic cardiovascular disease (ASCVD)-related events. Therefore, there is urgent need to treat ASCVD disease in T2DM earlier, more intensively, and with greater precision. Many factors concur to increase the risk of atherosclerosis, and multifactorial intervention remains the basis for effective prevention or reduction of atherosclerotic events. The role of anti-hyperglycemic medications in reducing the risk of ASCVD in subjects with T2DM has evolved over the past few years. Multiple cardiovascular outcome trials (CVOTs) with new and emerging glucose-lowering agents, namely SGLT2 inhibitors (SGLT2i) and GLP-1 receptor agonists (GLP1-RA), have demonstrated significant reductions of major cardiovascular events and additional benefits. This robust evidence has changed the landscape for managing people with T2DM. In addition to glycemic and ancillary extra-glycemic properties, SGLT2i and GLP1-RA might exert favorable effects on subclinical and clinical atherosclerosis. Therefore, the objective of this review is to discuss the available evidence supporting anti-atherosclerotic properties of SGLT2i and GLP1-RA, with a quick nod to sotagliflozin and tirzepatide.

Abstract
Obesity is a chronic, multifactorial disease in which accumulated excess body fat has a negative impact on health. Obesity continues to rise among the general population, resulting in an epidemic that shows no significant signs of decline. It is directly involved in development of cardiometabolic diseases, ischemic coronary heart disease peripheral arterial disease, heart failure, and arterial hypertension, producing global morbidity and mortality. Mainly, abdominal obesity represents a crucial factor for cardiovascular illness and also the most frequent component of metabolic syndrome. Recent evidence showed that Tirzepatide (TZP), a new drug including both Glucagon Like Peptide 1 (GLP-1) and Glucose-dependent Insulinotropic Polypeptide (GIP) receptor agonism, is effective in subjects with type 2 diabetes (T2D), lowering body weight, fat mass and glycated hemoglobin (HbA1c) also in obese or overweight adults without T2D. This review discusses the pathophysiological mechanisms and clinical aspects of TZP in treating obesity.

Abstract
Cardiovascular disease (CVD) and kidney disease are the main causes of morbidity and mortality in type 2 diabetes mellitus (T2DM). Globally, the incidence of T2DM continues to rise. A substantial increase in the burden of CVD and renal disease, alongside the socioeconomic implications, would be anticipated. Adopting a purely glucose-centric approach focusing only on glycemic targets is no longer adequate to mitigate the cardiovascular risks in T2DM. In the past decade, significant advancement has been achieved in expanding the pharmaceutical options for T2DM, with novel agents such as the sodium-glucose cotransporter type 2 (SGLT2) inhibitors and glucagon-like peptide receptor agonists (GLP-1 RAs) demonstrating robust evidence in cardiorenal protection. Combinatorial approaches comprising multiple pharmacotherapies combined in a single agent are an emerging and promising way to not only enhance patient adherence and improve glycemic control but also to achieve the potential synergistic effects for greater cardiorenal protection. In this review, we provide an update on the novel antidiabetic agents in the past decade, with an appraisal of the mechanisms contributing to cardiorenal protection. Additionally, we offer a glimpse into the landscape of T2DM management in the near future by providing a comprehensive summary of upcoming agents in early-phase trials.

OBJECTIVE Explore changes in biomarkers of β-cell function and insulin sensitivity and in efficacy profiles in baseline biomarker quartile analyses with tirzepatide compared to semaglutide. DESIGN Post hoc analysis of SURPASS-2 phase 3 trial (participants randomly assigned to receive weekly subcutaneous tirzepatide or semaglutide for 40 weeks). SETTING Post hoc analysis of 128 sites in 8 countries. PARTICIPANTS A total of 1879 participants with type 2 diabetes. INTERVENTIONS Once-weekly tirzepatide (5, 10, 15 mg) or semaglutide 1 mg. MAIN OUTCOMES MEASURES Change in homeostatic model assessment indices for pancreatic β-cell function (HOMA2-B) and for insulin resistance (HOMA2-IR), fasting glucagon, fasting C-peptide, and fasting insulin. RESULTS At week 40, a greater increase in HOMA2-B was seen with tirzepatide (5, 10, 15 mg) doses (96.9-120.4%) than with semaglutide 1 mg (84.0%) (P < .05). There was a greater reduction in HOMA2-IR with all doses of tirzepatide (15.5%-24.0%) than with semaglutide 1 mg (5.1%) (P < .05). Tirzepatide 10 and 15 mg resulted in a significant reduction in both fasting C-peptide (5.2%-6.0%) and fasting glucagon (53.0%-55.3%) compared with an increase of C-peptide (3.3%) and a reduction of glucagon (47.7%) with semaglutide 1 mg (P < .05). HbA1c and body weight reductions were greater with all tirzepatide doses than semaglutide within each HOMA2-B and HOMA2-IR baseline quartile. CONCLUSION In this post hoc analysis, improvements in HbA1c and weight loss were consistent and significantly higher with tirzepatide, regardless of baseline β-cell function and insulin resistance, compared with semaglutide.

Efficacy and safety of once-weekly tirzepatide for weight management compared to placebo: An updated systematic review and meta-analysis including the latest SURMOUNT-2 trial. Endocrine 2024:10.1007/s12020-024-03896-z. [PMID: 38850440 DOI: 10.1007/s12020-024-03896-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2024] [Accepted: 05/27/2024] [Indexed: 06/10/2024]
Abstract
AIM Tirzepatide, a newly developed dual glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist, has received approval for treating type 2 diabetes (T2D) and is currently being studied for its potential in long-term weight control. We aim to explore the safety and efficacy of once-weekly subcutaneous tirzepatide for weight loss in T2D or obese patients. METHODS A comprehensive search was performed on various databases including PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov from inception up to April 29, 2024, to identify randomized controlled trials (RCTs) that assessed the efficacy of once-weekly tirzepatide compared to a placebo in adults with or without T2D. The mean difference (MD) and risk ratio (RR) were calculated for continuous and dichotomous outcomes, respectively. The risk of bias was evaluated using the RoB-2 tool (Cochrane), while the statistical analysis was conducted utilizing RevMan 5.4.1 software. RESULTS Seven RCTs comprising 4795 individuals ranging from 12 to 72 weeks were identified. Compared to the placebo group, tirzepatide at doses of 5, 10, and 15 mg demonstrated significant dose-dependent weight loss. The mean difference (MD) in the percentage change in body weight (BW) was -8.07% (95% CI -11.01, -5.13; p < 0.00001), -10.79% (95% CI -13.86, -7.71; p < 0.00001), and -11.83% (95% CI -14.52, -9.14; p < 0.00001), respectively. Additionally, the MD in the absolute change in BW was -7.5 kg (95% CI -10.9, -4.1; p < 0.0001), -11.0 kg (95% CI -16.9, -5.2; p = 0.0002), and -11.5 kg (95% CI -16.2, -6.7; p < 0.00001), for the 5, 10, and 15 mg doses, respectively. All three doses of tirzepatide also significantly reduced body mass index and waist circumference. Furthermore, it led to a greater percentage of patients experiencing weight loss exceeding 5, 10, 15, 20, and 25%. Moreover, tirzepatide showed great success in reducing blood pressure, blood sugar levels, and lipid profiles. In terms of safety, gastrointestinal side effects were the most frequently reported adverse events in all three doses of tirzepatide groups, which were generally mild-to-moderate and transient. CONCLUSION Tirzepatide treatment could lead to remarkable and sustained weight loss that is well-tolerated and safe, representing a novel and valuable therapeutic strategy for long-term weight management.

Abstract
Background Tirzepatide, a glucose-dependent insulinotropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor agonist, is indicated for chronic weight management in adults with obesity or overweight as an adjunct to a reduced-calorie diet and increased physical activity. However, the safety profile of Tirzepatide-associated adverse events requires comprehensive evaluation. Methods The AE reports from the first quarter of 2022 to the third quarter of 2023 were selected by exploring the FDA Adverse Event Reporting System (FAERS) database. The new and unexpected potenial AE signals were detected using the disproportionality analysis, including reporting odds ratio(ROR), the proportional reporting ratio (PRR) the Bayesian confidence propagation neural network (BCPNN) and the empirical Bayes geometric mean(EBGM). Then the MedDRA was used to systematically classify the results. Results A total of 1,904,481 case reports were obtained from 2022Q2 to 2023Q3. Forty-sixth tirzepatide-induced ADRs at the preferred terms (PTs) level are associated with 8 system organ class In addition, this study uncovered multiple anticipated ADRs, such as gastrooesophageal reflux disease, dyspepsia, and vomiting, in line with the drug labels. Moreover, unexpected and significant ADRs at PTs level, such as incorrect dose administered, injection site haemorrhage, and increased appetite, were discovered and linked to Injury, poisoning, and procedural complications, General disorders and administration site conditions, and Metabolism and nutrition disorders at the System Organ Class level. Conclusion This study offered new perspectives on the monitoring, surveillance, and management of adverse drug reactions related to tirzepatide. The outcomes of severe adverse events and their respective detection signals, along with unexpected significant adverse event signals, are important to consider in efforts to enhance clinical medication safety when using tirzepatide.

Abstract
Although good glycemic control in patients with type 2 diabetes (T2D) can prevent cardiovascular complications, many diabetic patients still have poor optimal control. A new class of antidiabetic drugs (e.g., glucagon-like peptide-1-GLP-1 receptor agonists, sodium-glucose co-transporters-SGLT2 inhibitors), in addition to the low hypoglycemic effect, exert multiple beneficial effects at a metabolic and cardiovascular level, through mechanisms other than antihyperglycemic agents. This review aims to discuss the effects of these new antidiabetic drugs, highlighting cardiovascular and metabolic benefits, through the description of their action mechanisms as well as available data by preclinical and clinical studies. Moreover, new innovative tools in the T2D field will be described which may help to advance towards a better targeted T2D personalized care in future.

Abstract
OBJECTIVE The study objective was to characterize subgroups of Asia-Pacific patients with type 2 diabetes who achieved different glycated hemoglobin (HbA1c) targets on tirzepatide treatment. METHODS This was a post hoc analysis of the SURPASS AP-Combo study. Baseline characteristics, changes in metabolic markers, and safety were compared between tirzepatide-treated patients achieving HbA1c <7.0% (<53 mmol/mol) and those achieving ≥7.0% (≥53 mmol/mol) at week 40. Among patients achieving HbA1c <7.0% (<53 mmol/mol), further comparisons were conducted among subgroups achieving HbA1c <5.7% (<39 mmol/mol), 5.7% to 6.5% (39 to 48 mmol/mol), and >6.5% to <7.0% (>48 to <53 mmol/mol). RESULTS Five hundred ninety-eight patients on tirzepatide treatment without rescue medication were included (56.9% male; mean age: 53.1 years; mean baseline HbA1c: 8.7% [71.6 mmol/mol]). Patients achieving HbA1c <7.0% (<53 mmol/mol) versus ≥7.0% (≥53 mmol/mol) were slightly younger with a shorter disease duration and lower HbA1c at baseline, and they had greater improvements in HbA1c, fasting serum glucose, body weight, BMI, waist circumference, waist-height ratio, diastolic blood pressure, lipids, and self-monitored blood glucose at week 40. Patients achieving HbA1c <5.7% (<39 mmol/mol) versus those achieving 5.7% to 6.5% (39 to 48 mmol/mol) and those achieving >6.5% to <7.0% (>48 to <53 mmol/mol) were much younger, had much lower HbA1c, and had further improvements in metabolic markers. Tirzepatide treatment was well tolerated irrespective of the HbA1c level achieved, with a low incidence of hypoglycemic events. CONCLUSIONS These findings may help to inform clinical decisions in Asia-Pacific patients with type 2 diabetes.

Abstract
Chronic kidney disease is a debilitating condition associated with significant morbidity and mortality. In recent years, the kidney effects of incretin-based therapies, particularly glucagon-like peptide-1 receptor agonists (GLP-1RAs), have garnered substantial interest in the management of type 2 diabetes and obesity. This review delves into the intricate interactions between the kidney, GLP-1RAs, and glucagon, shedding light on their mechanisms of action and potential kidney benefits. Both GLP-1 and glucagon, known for their opposing roles in regulating glucose homeostasis, improve systemic risk factors affecting the kidney, including adiposity, inflammation, oxidative stress, and endothelial function. Additionally, these hormones and their pharmaceutical mimetics may have a direct impact on the kidney. Clinical studies have provided evidence that incretins, including those incorporating glucagon receptor agonism, are likely to exhibit improved kidney outcomes. Although further research is necessary, receptor polypharmacology holds promise for preserving kidney function through eliciting vasodilatory effects, influencing volume and electrolyte handling, and improving systemic risk factors.

Br J Pharmacol 2024; 181:1874-1885.

Abstract
BACKGROUND AND PURPOSE Cotadutide is a dual GLP-1 and glucagon receptor agonist with balanced agonistic activity at each receptor designed to harness the advantages on promoting liver health, weight loss and glycaemic control. We characterised the effects of cotadutide on glucose, insulin, GLP-1, GIP, and glucagon over time in a quantitative manner using our glucose dynamics systems model (4GI systems model), in combination with clinical data from a multiple ascending dose/Phase 2a (MAD/Ph2a) study in overweight and obese subjects with a history of Type 2 diabetes mellitus (NCT02548585). EXPERIMENTAL APPROACH The cotadutide PK-4GI systems model was calibrated to clinical data by re-estimating only food related parameters. In vivo cotadutide efficacy was scaled based on in vitro potency. The model was used to explore the effect of weight loss on insulin sensitivity and predict the relative contribution of the GLP-1 and glucagon receptor agonistic effects on glucose. KEY RESULTS Cotadutide MAD/Ph2a clinical endpoints were successfully predicted. The 4GI model captured a positive effect of weight loss on insulin sensitivity and showed that the stimulating effect of glucagon on glucose production counteracts the GLP-1 receptor-mediated decrease in glucose, resulting in a plateau for glucose decrease around a 200-μg cotadutide dose. CONCLUSION AND IMPLICATIONS The 4GI quantitative systems pharmacology model was able to predict the clinical effects of cotadutide on glucose, insulin, GLP-1, glucagon and GIP given known in vitro potency. The analyses demonstrated that the quantitative systems pharmacology model, and its successive refinements, will be a valuable tool to support the clinical development of cotadutide and related compounds.

Abstract
Despite its considerable and growing burden, there are currently no Food and Drug Administration-approved treatments for metabolic dysfunction-associated steatotic liver disease or its progressive form, metabolic dysfunction-associated steatohepatitis (MASH). Several glucagon-like peptide-1 receptor agonists (GLP-1RAs) and other agents are in various phases of clinical development for use in MASH; an ideal therapy should reduce liver fat content, improve chronic liver disease, help mitigate metabolic comorbidities and decrease all-cause mortality. Because of interconnected disease mechanisms, metabolic dysfunction-associated steatotic liver disease/MASH often coexists with type 2 diabetes (T2D), obesity and cardiovascular disease. Various GLP-1RAs are Food and Drug Administration-approved for use in T2D, and two, liraglutide and semaglutide, are approved for overweight and obesity. GLP-1RAs decrease glucose levels and body weight and improve cardiovascular outcomes in people with T2D who are at high risk of cardiovascular disease. In addition, GLP-1RAs have been reported to reduce liver fat content and liver enzymes, reduce oxidative stress and improve hepatic de novo lipogenesis and the histopathology of MASH. Weight loss may contribute to these effects; however, the exact mechanisms are unknown. Adverse events that are commonly associated with GLP-1RAs include vomiting, nausea and diarrhoea. There is a lack of evidence from meta-analyses regarding the increased risk of acute pancreatitis and various forms of cancer with GLP-1RAs. Large-scale, phase 3 trials, which will provide definitive data on GLP-1RAs and other potential therapies in MASH, are ongoing. Given the spectrum of modalities under investigation, it is hoped that these trials will support the identification of pharmacotherapies that provide clinical benefit for patients with MASH.

Abstract
Objectives In recent years, new hypoglycaemic drugs that affect the incretin system have become increasingly popular in the treatment of type 2 diabetes mellitus (T2DM): glucagon-like receptor 1 agonists (GLP1RAs), dipeptidyl peptidase 4 inhibitors (DPP4is) and the recently developed dual glucagon-like receptor 1 agonist and glucose-dependent insulinotropic polypeptide (tirzepatide). Their main role of these drugs is to normalise blood glucose levels. In addition, GLP1RAs are approved for the treatment of excessive body weight. The efficacy of drugs affecting the incretin system is well described in the literature, however, there are still only few reports about their safety. This review aims to summarize the results of current research and meta-analyses on risk of acute pancreatitis (AP) during incretin-affecting drugs treatment. Methods A narrative review was performed using present literature in an attempt to identify the relationship between AP and incretin-affecting drugs. The following keywords were used: acute pancreatitis, glucagon-like receptor 1 agonists, dipeptidyl peptidase 4 inhibitors and tirzepatide. Results It was demonstrated that the use of DPP4is is safe for the majority of patients with T2DM, whereas a risk of AP should be noted in case of GLP1RAs therapy. To date, most studies found no significant association between tirzepatide therapy and the increased risk of AP. Conclusion The majority of studies have shown that DPP4is, GLP1RAs and tirzepatide are effective and safe in most T2DM patients. However, the follow-up time for patients treated with tirzepatide is short, therefore more studies are required to confirm the safety of this drug.

Abstract
Obesity, a rapidly expanding epidemic worldwide, is known to exacerbate many medical conditions, making it a significant factor in multiple diseases and their associated complications. This threatening epidemic is linked to various harmful conditions such as type 2 diabetes mellitus, hypertension, metabolic dysfunction-associated steatotic liver disease, polycystic ovary syndrome, cardiovascular diseases (CVDs), dyslipidemia, and cancer. The rise in urbanization and sedentary lifestyles creates an environment that fosters obesity, leading to both psychosocial and medical complications. To identify individuals at risk and ensure timely treatment, it is crucial to have a better understanding of the pathophysiology of obesity and its comorbidities. This comprehensive review highlights the relationship between obesity and obesity-associated complications, including type 2 diabetes, hypertension, (CVDs), dyslipidemia, polycystic ovary syndrome, metabolic dysfunction-associated steatotic liver disease, gastrointestinal complications, and obstructive sleep apnea. It also explores the potential mechanisms underlying these associations. A thorough analysis of the interplay between obesity and its associated complications is vital in developing effective therapeutic strategies to combat the exponential increase in global obesity rates and mitigate the deadly consequences of this polygenic condition.

Abstract
PURPOSE Chronic kidney disease (CKD) is one of the most common complications of type 2 diabetes (T2D), and CKD-related disability and mortality are increasing despite the recent advances in diabetes management. The dual GIP/GLP-1 receptor agonist tirzepatide is among the furthest developed multi-agonists for diabetes care and has so far displayed promising nephroprotective effects. This review aims to summarize the evidence regarding the nephroprotective effects of glucagon-like peptide-1 receptor agonists (GLP-1RA) and tirzepatide and the putative mechanisms underlying the favorable renal profile of tirzepatide. METHODS A comprehensive literature search was performed from inception to July 31st 2023 to select research papers addressing the renal effects of GLP-1RA and tirzepatide. RESULTS The pathogenesis of CKD in patients with T2D likely involves many contributors besides hyperglycemia, such as hypertension, obesity, insulin resistance and glomerular atherosclerosis, exerting kidney damage through metabolic, fibrotic, inflammatory, and hemodynamic mechanisms. Tirzepatide displayed an unprecedented glucose and body weight lowering potential, presenting also with the ability to increase insulin sensitivity, reduce systolic blood pressure and inflammation and ameliorate dyslipidemia, particularly by reducing triglycerides levels. CONCLUSION Tirzepatide is likely to counteract most of the pathogenetic factors contributing to CKD in T2D, potentially representing a step forward in incretin-based therapy towards nephroprotection. Further evidence is needed to understand its role in renal hemodynamics, fibrosis, cell damage and atherosclerosis, as well as to conclusively show reduction of hard renal outcomes.

[PMID: 38932909 PMCID: PMC11196572 DOI: 10.1007/s40200-024-01412-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 02/22/2024] [Indexed: 06/28/2024]
Abstract
Purpose Excess body fat, insulin resistance, and abnormal lipid levels signal type 2 diabetes mellitus (DM2). Globally, 536.6 million people suffer from DM2, projected to rise to 783.2 million by 2045. Obesity fuels insulin resistance and DM2 development, with weight loss significantly improving glycemic control. Titrzepatide (TZP), a dual GIP and GLP-1 receptor agonist, proves highly effective in controlling hyperglycemia, stimulating insulin secretion, and promoting weight loss. TZP, holds promise as a treatment for DM2, surpassing insulin and GLP-1. The study aimed to meticulously assess the safety and efficacy of various doses, offering insights into optimal therapeutic strategies for managing DM2. Methods This study aimed to comprehensively evaluate the safety and efficacy of TZP in treating DM2. The primary focus of the inclusion criteria was on trials comparing TZP with a placebo until November 23, 2023, excluding patients with certain comorbidities. Data extraction included key parameters, and outcomes were assessed for HbA1c levels, weight changes, fasting serum glucose levels, and various adverse events. Quality assessment utilized the Cochrane Collaboration's risk-of-bias tool, and a network meta-analysis explored outcomes across different TZP dosages. Results This meta-analysis systematically reviewed ten studies on TZP for DM2. Results revealed significant reductions in HbA1c with TZP 10 mg (19%) and TZP 15 mg (31%) compared to TZP 5 mg (MD: -0.19 and MD: -0.32, respectively). Additionally, weight reduction was notable for TZP 10 mg (MD: -1.96) and TZP 15 mg (MD: -3.31). Fasting serum glucose showed improvement with TZP 15 mg (MD:-6.71). Gastrointestinal events increased with higher doses, yet without statistical significance. Death, nausea, diarrhea, vomiting, dyspepsia, decreased appetite, injection site reaction, hypoglycemia, treatment discontinuation, and serious adverse events showed no significant differences across doses. Conclusion TZP effectively lowers HbA1c and induces weight loss across its three doses for type 2 diabetes management. The higher dose (15 mg) significantly reduces fasting serum glucose, with increased adverse events observed at higher doses. Dose-specific patterns for adverse effects emphasize the need to balance therapeutic benefits and risks. Further research is crucial for refining clinical applications and understanding TZP's role in DM2 management across doses.

Abstract
In recent years, significant progress has been made to pharmacologically combat the obesity pandemic, particularly with regard to biochemically tailored drugs that simultaneously target the receptors for glucagon-like peptide-1 (GLP-1) and the glucose-dependent insulinotropic polypeptide (GIP). But while the pharmacological benefits of GLP-1 receptor (GLP-1R) agonism are widely acknowledged, the role of the GIP system in regulating systems metabolism remains controversial. When given in adjunct to GLP-1R agonism, both agonism and antagonism of the GIP receptor (GIPR) improves metabolic outcome in preclinical and clinical studies, and despite persistent concerns about its potential obesogenic nature, there is accumulating evidence indicating that GIP has beneficial metabolic effects via central GIPR agonism. Nonetheless, despite growing recognition of the GIP system as a valuable pharmacological target, there remains great uncertainty as to where and how GIP acts in the brain to regulate metabolism, and how GIPR agonism may differ from GIPR antagonism in control of energy metabolism. In this review we highlight current knowledge on the central action of GIP, and discuss open questions related to its multifaceted biology in the brain and the periphery.
