Abstract
INTRODUCTION Tirzepatide is a novel hypoglycemic agent for type 2 diabetes mellitus (T2DM). However, the pathophysiology of T2DM in Asians is different from that in non-Asians, and there is no evidence to explain the differences in the efficacy and safety of tirzepatide between different races. METHODS A literature search was conducted in China National Knowledge Infrastructure (CNKI), PubMed, Cochrane Library, Clinical Trials.gov, and Embase databases for clinical studies of tirzepatide for T2DM. The data extraction process was done independently by two authors. All analyses were performed using STATA 14.0 software and Review Manager 5.3 software. RESULTS A total of 2118 patients with T2DM from 6 studies were involved, with doses of tirzepatide ranging from 5 to 15 mg administered subcutaneously once weekly. The results showed that compared with control/placebo, tirzepatide was more effective in decreasing fasting blood glucose (FBG) in non-Asians than in Asians, and 10 mg rather than 15 mg was the optimal dose to decrease FBG. Similarly, non-Asians were more effective than Asians in improving glycated hemoglobin (HbA1c). Asians were significantly more effective than non-Asians in reducing body weight and ≥ 5% weight loss. In terms of adverse events, the incidence of gastrointestinal adverse events was higher in Asians than in non-Asians at the same dose, while the incidence of metabolic and nutrition disorders was higher in non-Asians than in Asians. CONCLUSION Tirzepatide is a novel agent for the treatment of diabetes and has different efficacy in Asians and non-Asians. Asians were more likely to experience weight loss and gastrointestinal adverse events, whereas non-Asians were more likely to have better glycemic control and more metabolic and nutritional disorders.

Clin Pharmacokinet 2024; 63:255-267.

Abstract
BACKGROUND Cotadutide is a dual glucagon-like peptide-1 (GLP-1) and glucagon (GCG) receptor agonist peptide. The objective of this analysis was to develop a population pharmacokinetic (popPK) model of cotadutide, and to identify any potential effect on the PK from intrinsic and extrinsic covariates. METHODS The popPK analysis utilized a non-linear mixed-effects modeling approach using the data from 10 clinical studies in different participant categories following once-daily subcutaneous dose administration ranging from 20 to 600 μg. Additionally, the covariates affecting cotadutide exposure were quantified, and the model performance was evaluated through the prediction-corrected visual predictive checks. RESULTS A one-compartment model with first-order absorption and elimination adequately described the data as confirmed via visual predictive check plots and parameter plausibility. The mean values for cotadutide apparent clearance (CL/F), apparent volume of distribution (V/F), absorption rate constant (Ka), and half-life were 1.05 L/h, 20.0 L, 0.38 h-1, and 13.3 hours, respectively. Covariate modeling identified body weight, alanine transaminase, albumin, anti-drug antibody (ADA) titer values, formulation strength and injection device, and participant categories as significant covariates on PK parameters, where ADAs have been identified to decrease cotadutide clearance. The model demonstrated that a 150-kg participant was estimated to have 30% lower for both AUC and Cmax and a 66 kg participant was estimated to have 35% higher for both AUC and Cmax relative to a reference individual with a median weight of 96 kg. CONCLUSIONS A popPK model was developed for cotadutide with cotadutide clinical data, and the impact of the statistically significant covariates identified was not considered clinically meaningful. The popPK model will be used to evaluate exposure-response relationships for cotadutide clinical data.

Abstract
CONTEXT Antidrug antibodies (ADA) can potentially affect drug pharmacokinetics, safety, and efficacy. OBJECTIVE This work aimed to evaluate treatment-emergent (TE) ADA in tirzepatide (TZP)-treated participants across 7 phase 3 trials and their potential effect on pharmacokinetics, efficacy, and safety. METHODS ADA were assessed at baseline and throughout the study until end point, defined as week 40 (SURPASS-1, -2, and -5) or week 52 (SURPASS-3, -4, Japan-Mono, and Japan-Combo). Samples for ADA characterization were collected at SURPASS trial sites. Participants included ADA-evaluable TZP-treated patients with type 2 diabetes (N = 5025). Interventions included TZP 5, 10, or 15 mg. ADA were detected and characterized for their ability to cross-react with native glucose-dependent insulinotropic polypeptide (nGIP) and glucagon-like peptide-1 (nGLP-1), neutralize tirzepatide activity on GIP and GLP-1 receptors, and neutralize nGIP and nGLP-1. RESULTS TE ADA developed in 51.1% of tirzepatide-treated patients. Proportions were similar across dose groups. Maximum ADA titers ranged from 1:20 to 1: 81 920 among TE ADA+ patients. Neutralizing antibodies (NAb) against TZP activity on GIP and GLP-1 receptors were observed in 1.9% and 2.1% of patients, respectively. Less than 1.0% of patients had cross-reactive NAb against nGIP or nGLP-1. TE ADA status, ADA titer, and NAb status had no effect on the pharmacokinetics or efficacy of TZP. More TE ADA+ patients experienced hypersensitivity reactions or injection site reactions than TE ADA- patients. The majority of hypersensitivity and injection site reactions were nonserious and nonsevere, and most events occurred and/or resolved irrespective of TE ADA status or titer. CONCLUSION Immunogenicity did not affect TZP pharmacokinetics or efficacy. The majority of hypersensitivity or injection site reactions experienced by TE ADA+ patients were mild to moderate in severity.

Diabetes Obes Metab 2023; 25:1080-1090. [PMID: 36541037 DOI: 10.1111/dom.14956] [Citation(s) in RCA: 17] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 12/12/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022]
Abstract
AIM To assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of basal insulin Fc (BIF; LY3209590), a fusion protein combining a novel single-chain insulin variant together with human IgG2 Fc domain, following single and multiple once-weekly BIF administration. MATERIALS AND METHODS The single ascending dose, 15-day study assessed four BIF doses (5-35 mg) in healthy participants and people with type 2 diabetes (T2D). In the 6-week multiple ascending dose study, people with T2D, previously treated with basal insulin, received insulin glargine daily or a one-time loading dose of BIF followed by 5 weeks of once-weekly dosing (1-10 mg). Safety, tolerability and PK and glucose PD were examined. RESULTS Mean ages of people with T2D (N = 57) and healthy participants (N = 16) in the single-dose study were 58.4 and 35.8 years, respectively; mean body mass index values were 29.5 and 26.1 kg/m2 . BIF had a PK half-life of approximately 17 days, which led to a sustained, dose-dependent decrease in fasting blood glucose for 5 days or longer. No severe hypoglycaemia was observed. The 6-week ascending dose study included 33 people with T2D aged 40-69 years. BIF showed a low peak-to-trough ratio of 1.14 after the last dose at week 6 (steady state). Over 6 weeks, BIF seven-point glucose profiles remained constant and were similar to insulin glargine. Rates and duration of BIF hypoglycaemic events were similar to insulin glargine. CONCLUSIONS BIF was well tolerated and the PK/PD profile enabled once-weekly dosing with minimal variation in exposure in a treatment interval of 1 week. The findings suggest BIF is suitable for further development as a weekly basal insulin in people with diabetes.

Abstract
The global burden of chronic disorders such as Parkinson's disease (PD) has rapidly increased over recent decades. Despite an increasing understanding of PD pathophysiology, there are no effective therapies capable of stopping or slowing the progression of this neurological condition. It has been suggested that type 2 diabetes mellitus (T2DM) may be a risk factor for PD and comorbid T2DM may worsen PD symptoms, as well as accelerate neurodegeneration. In fact, the similar pathological mechanisms shared by PD and T2DM have inspired several studies on the therapeutic potential of T2DM drugs against PD, among which glucagon-like peptide-1 receptor (GLP-1R) agonists are promising candidates. Here, we highlight the mechanisms linking T2DM and PD, as well as the links between insulin resistance (IR) and PD patients' risk of developing cognitive deficits. We also briefly review the effects of GLP-1R agonists on PD and discuss how the successful use of these substances in preclinical models of PD has paved the way for PD clinical trials. We further discuss how recent evidence on the beneficial effects of dulaglutide on cognitive function of T2DM patients may have important implications for PD drug repurposing.

Abstract
AIM To assess the efficacy and safety of polyethylene glycol loxenatide (PEX168), a new glucagon-like peptide-1 receptor agonist, as an add-on to metformin therapy in Chinese patients with type 2 diabetes (T2D). MATERIALS AND METHODS This was a multicentre, randomized, double-blind, placebo-controlled phase 3b trial. After metformin monotherapy (≥1500 mg/day) for 8 weeks or more, patients with uncontrolled T2D (HbA1c of 7.0%-10.5%) from 44 sites were randomized (1:1:1) to metformin + placebo, metformin + PEX168 100 μg, and metformin + PEX168 200 μg. The core treatment period lasted for 24 weeks, followed by a 28-week extension period. The primary endpoint was the change in HbA1c levels at week 24. The main secondary endpoint was the proportion of patients with an HbA1c of less than 7.0% at week 24. RESULTS The least-square mean (standard error) change in HbA1c levels was significantly greater (P < .001 for superiority) in the PEX168 groups (-1.16% [0.08%] and -1.14% [0.08%] with 100 and 200 μg, respectively) than in the placebo group (0.35% [0.08%]). The proportion of patients with an HbA1c of less than 7.0% at week 24 was significantly higher in the PEX168 100 μg (37.4%) and PEX168 200 μg (40.6%) groups than in the placebo group (16.8%; both P < .001). The gastrointestinal reactions were mild; the risks of hypoglycaemia and weight gain did not increase. Anti-PEX168 antibodies were noted in less than 2% of patients. No treatment-emergent serious adverse events occurred. CONCLUSION The subcutaneous injection of PEX168 once a week can effectively, continuously and safely improve HbA1c levels in patients with T2D when combined with metformin.

Abstract
AIM To assess the efficacy, safety and pharmacokinetic/pharmacodynamic properties of efpeglenatide, a long-acting glucagon-like peptide-1 receptor agonist, in patients with type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS Two randomized, double-blind, placebo-controlled phase 2 trials were conducted. The single-dose study (n = 48) was a first-in-patient, sequential dose-escalation study. Patients received a single subcutaneous injection of efpeglenatide (2-100 μg/kg) or placebo. The repeated-dose study (n = 71) was a multiple-ascending-dose trial. Patients received weekly (1, 2 or 4 mg once weekly; 8-week period) or monthly (8, 12 or 16 mg once monthly; 9-week period) subcutaneous injections of efpeglenatide or placebo (without titration). RESULTS Both studies demonstrated dose-proportional increases in efpeglenatide serum concentrations. The median time to attain maximum serum concentration (tmax ) for efpeglenatide ranged from 72 to 144 hours in the single-dose study and from 48 to 120 hours in the repeated-dose study (following final dose). Geometric mean t1/2 ranged from 135 to 180 hours across studies. Peak-to-trough ratios in the repeated-dose study ranged from 1.3 to 1.4 with once-weekly dosing and from 5.9 to 12.9 with once-monthly dosing. Following a single dose of efpeglenatide 14-100 μg/kg, fasting plasma glucose and postprandial plasma glucose levels were decreased at week 1 and remained below baseline levels for ≥3 weeks post-dosing. Repeated doses of efpeglenatide led to significant reductions in glycated haemoglobin vs placebo. In both studies, efpeglenatide was generally well tolerated. Gastrointestinal disorders were the most frequently reported treatment-emergent adverse events in efpeglenatide-treated patients. CONCLUSIONS The delayed tmax, long half-life, and low peak-to-trough ratios observed demonstrate potential for improved efficacy and dosing flexibility, with good tolerability of efpeglenatide in patients with T2D.

Abstract
Given the limited efficacy of available pharmacotherapies for treatment of alcohol use disorder (AUD), the need for new medications is substantial. Preclinical studies have shown that acute administration of glucagon-like peptide-1 receptor (GLP-1R) agonists inhibits various ethanol-related behaviours, indicating this system as a potential target for AUD. However, the effects of long-term systemic treatment of GLP-1R agonists on ethanol intake in male and female rodents are to date unknown. Therefore, we investigated the effects of 9 or 5 weeks of once weekly administration of dulaglutide, a long-acting GLP-1R agonist, on ethanol intake in male and female rats. The ethanol intake during treatment discontinuation was also monitored. In an initial attempt to identify preliminary underlying mechanisms, the effects of 9 weeks of once weekly dulaglutide treatment on monoaminergic signalling in reward-related areas were explored in both sexes. We found that 9 or 5 weeks of once weekly dulaglutide treatment reduced ethanol intake and preference in male and female rats. Following discontinuation of dulaglutide treatment, the decrease in ethanol consumption was prolonged in males, but not females. We demonstrated that 9 weeks of dulaglutide treatment differentially influenced monoaminergic signalling in reward-related areas of male and female rats. Collectively, these data imply that the GLP-1R attracts interest as a potential molecular target in the medical treatment of AUD in humans: more specifically, dulaglutide should be evaluated as a potential medication for treatment thereof.

Abstract
Most immune responses to biotherapeutic proteins involve the development of anti-drug antibodies (ADAs). New drugs must undergo immunogenicity assessments to identify potential risks at early stages in the drug development process. This immune response is T cell-dependent. Ex vivo assays that monitor T cell proliferation often are used to assess immunogenicity risk. Such assays can be expensive and time-consuming to carry out. Furthermore, T cell proliferation requires presentation of the immunogenic epitope by major histocompatibility complex class II (MHCII) proteins on antigen-presenting cells. The MHC proteins are the most diverse in the human genome. Thus, obtaining cells from subjects that reflect the distribution of the different MHCII proteins in the human population can be challenging. The allelic frequencies of MHCII proteins differ among subpopulations, and understanding the potential immunogenicity risks would thus require generation of datasets for specific subpopulations involving complex subject recruitment. We developed TCPro, a computational tool that predicts the temporal dynamics of T cell counts in common ex vivo assays for drug immunogenicity. Using TCPro, we can test virtual pools of subjects based on MHCII frequencies and estimate immunogenicity risks for different populations. It also provides rapid and inexpensive initial screens for new biotherapeutics and can be used to determine the potential immunogenicity risk of new sequences introduced while bioengineering proteins. We validated TCPro using an experimental immunogenicity dataset, making predictions on the population-based immunogenicity risk of 15 protein-based biotherapeutics. Immunogenicity rankings generated using TCPro are consistent with the reported clinical experience with these therapeutics.

Abstract
INTRODUCTION To evaluate efficacy and safety data of dulaglutide in Chinese patients with type 2 diabetes mellitus (T2DM) who had inadequate glycemic control with 1-2 oral antihyperglycemic medications (OAMs). METHODS This is a subgroup analysis of a phase 3, open-label, randomized, parallel-arm, 52-week study in Chinese patients aged ≥ 18 years with T2DM who had inadequate glycemic control with OAMs (glycated hemoglobin [HbA1c] ≥ 7.0% and ≤ 11.0%). The primary endpoint was assessment of the noninferiority of dulaglutide 1.5 mg as measured by change in HbA1c, compared with insulin glargine (glargine), using a 0.4% noninferiority margin at week 26. RESULTS A total of 607 patients from China were randomized 1:1:1 to once-weekly dulaglutide 1.5 or 0.75 mg or once-daily glargine. At week 26, the least squares mean (LSM) change from baseline in HbA1c was greater with dulaglutide 1.5 mg (- 1.67%) and dulaglutide 0.75 mg (- 1.31%) compared with glargine (- 1.11%). The LSM (95% confidence interval) for the difference of dulaglutide 1.5 mg and 0.75 mg vs glargine was - 0.56% (- 0.75 to - 0.37) and - 0.20% (- 0.39 to - 0.01), respectively. Both doses of dulaglutide were noninferior and superior to glargine at 26 weeks and 52 weeks (two-sided P value < 0.05). The mean body weight decreased (P < 0.001) and total hypoglycemia rates were lower (P < 0.05) in the dulaglutide groups compared with the glargine group. Gastrointestinal adverse events (AEs) were the most frequently reported AEs in dulaglutide groups. CONCLUSION Both doses of dulaglutide are efficacious and tolerable in Chinese patients with T2DM who had inadequate glycemic control on OAMs. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT01648582.

Abstract
Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1 RA) with a long elimination half-life, allowing subcutaneous (sc) administration once per week. Both the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) recently approved once-weekly sc semaglutide for the treatment of type 2 diabetes mellitus (T2DM). The weight loss efficacy of once-weekly sc semaglutide appears to be superior compared with the other once-weekly GLP-1 RAs in patients with T2DM. Semaglutide was recently evaluated as an antiobesity drug in a phase II dose-finding trial, which demonstrated superior weight loss efficacy of once daily sc semaglutide compared with both placebo and once daily 3.0 mg liraglutide in patients with obesity but without T2DM. The magnitude of semaglutide-induced weight loss in this study exceeded the criteria of both the EMA and FDA for antiobesity drugs, and there were no safety concerns, indicating the eligibility of once daily sc semaglutide as a future antiobesity drug.

Diabetes Obes Metab 2019; 21:234-243.

Abstract
AIM To compare the efficacy and safety of once-weekly dulaglutide with that of insulin glargine in combination with metformin and/or a sulphonylurea in mainly Asian patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS In this 52-week, randomized, parallel-arm open-label study, we enrolled patients aged ≥18 years with T2DM for at least 6 months and a glycated haemoglobin (HbA1c) concentration ≥53.0 mmol/mol (7.0%) and ≤96.7 mmol/mol (11.0%). The primary outcome was change in HbA1c from baseline to week 26 to determine non-inferiority of dulaglutide 1.5 mg versus glargine. RESULTS A total of 774 patients from China, South Korea, Mexico and Russia were randomly assigned (1:1:1) to dulaglutide 1.5 mg, dulaglutide 0.75 mg or glargine treatment groups. The patients' mean age was 55 years and the average T2DM duration was ~8 years. The least squares mean (SE) changes from baseline in HbA1c at 26 weeks were - 18.9 (0.73) mmol/mol (-1.73 [0.067]%) for dulaglutide 1.5 mg and -14.5 (0.73) mmol/mol (-1.33 [0.067]%) for dulaglutide 0.75 mg, compared with -12.7 (0.73) mmol/mol (-1.16 [0.067]%) for glargine. Statistical criteria for superiority were met with both dulaglutide 1.5 mg and dulaglutide 0.75 mg. More patients in the dulaglutide 1.5 and 0.75 mg groups achieved HbA1c target <53.0 mmol/mol (<7.0%) than in the glargine group at week 26 (P < 0.001 and P = 0.004, respectively). Body weight decreased with dulaglutide and increased with glargine. The incidence and rate of total hypoglycaemia were lower with dulaglutide versus glargine. Gastrointestinal adverse events, including diarrhoea and nausea, were the most frequently reported for patients taking dulaglutide. CONCLUSIONS Once-weekly dulaglutide provides greater improvement in HbA1c, with weight loss and less hypoglycaemia, than once-daily insulin glargine in a population of mainly Asian patients with T2DM who had failed to achieve optimal glycaemic control on metformin and/or a sulphonylurea.

[PMID: 30156747 DOI: 10.1002/dmrr.3070] [Citation(s) in RCA: 141] [Impact Index Per Article: 28.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 07/30/2018] [Accepted: 08/18/2018] [Indexed: 02/06/2023]
Abstract
Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) are an important class of drugs with a well-established efficacy and safety profile in patients with type 2 diabetes mellitus. Agents in this class are derived from either exendin-4 (a compound present in Gila monster venom) or modifications of human GLP-1 active fragment. Differences among these drugs in duration of action (ie, short-acting vs long-acting), effects on glycaemic control and weight loss, immunogenicity, tolerability profiles, and administration routes offer physicians several options when selecting the most appropriate agent for individual patients. Patient preference is also an important consideration. The aim of this review is to discuss the differences between and similarities of GLP-1 RAs currently approved for clinical use, focusing particularly on the properties characterising the single short-acting and long-acting GLP-1 RAs rather than on their individual efficacy and safety profiles. The primary pharmacodynamic difference between short-acting (ie, exenatide twice daily and lixisenatide) and long-acting (ie, albiglutide, dulaglutide, exenatide once weekly, liraglutide, and semaglutide) GLP-1 RAs is that short-acting agents primarily delay gastric emptying (lowering postprandial glucose) and long-acting agents affect both fasting glucose (via enhanced glucose-dependent insulin secretion and reduced glucagon secretion in the fasting state) and postprandial glucose (via enhanced postprandial insulin secretion and inhibition of glucagon secretion). Other advantages of long-acting GLP-1 RAs include smaller fluctuations in plasma drug concentrations, improved gastrointestinal tolerability profiles, and simpler, more convenient administration schedules (once daily for liraglutide and once weekly for albiglutide, dulaglutide, the long-acting exenatide formulation, and semaglutide), which might improve treatment adherence and persistence.

Abstract
Unimolecular dual incretins derived from hybridized glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) sequences have demonstrated synergistic reduction of adiposity in animal models and reductions of hyperglycemia in short-duration human trials. Here, we extend the characterization of NNC0090-2746 (also known as RG7697), a fatty-acylated dual agonist possessing in vitro balanced GIPR and GLP-1R agonism. In this 12-week, randomized, placebo-controlled, double-blind phase 2a trial, patients with type 2 diabetes inadequately controlled with metformin received 1.8 mg of NNC0090-2746 or placebo subcutaneously once daily. Liraglutide 1.8 mg (Victoza), starting with 2-week dose escalation, was administered subcutaneously once daily as an open-label reference arm. Measurements were collected at regular intervals after randomization. NNC0090-2746 significantly improved glycemic control and reduced body weight compared with placebo. Total cholesterol, alone among a range of lipid parameters, and leptin were both significantly reduced compared with placebo. Treatment with NNC0090-2746 was generally safe and well tolerated.

Abstract
GW002 is a recombinant protein engineered by fusing the C-terminal region of human glucagon-like peptide-1 (GLP-1) to the N-terminal region of human serum albumin (HSA) with a peptide linker. This study aims to evaluate its anti-diabetic effects both in vitro and in vivo. The GLP-1 receptor-dependent luciferase reporter plasmid was transiently transfected in NIT-1 cells to calculate the half-maximal concentration (EC50) for GLP-1 receptor activation, and normal ICR mice and diabetic KKAy mice were acutely injected with GW002 (1, 3, 9 mg/kg) subcutaneously to evaluate the hypoglycemic action, while the diabetic KKAy and db/db mice were treated with GW002 once daily for 7 weeks to evaluate the effects on glucose metabolism. The results showed that GW002 activated GLP-1 receptor in NIT-1 cells with higher EC50 versus exendin-4 (46.7 vs. 7.89 nM), and single subcutaneous injection of GW002 at doses of 1, 3 and 9 mg/kg efficiently restrained the glycemia variation after oral glucose loading in ICR mice for at least 4 d, as well as reducing the non-fasting blood glucose in KKAy mice for about 2 d, while repeated injections of GW002 significantly improved abnormal glycaemia, hemoglobin (Hb)A1c levels, oral glucose intolerance and β-cell function in diabetic db/db mice. These results suggested that GW002 showed prolonged hypoglycemic action by activating its cognate receptor and provided efficient control of glucose metabolism. Thus GW002 may be a potential treatment for the management of type 2 diabetes.

Efficacy and safety of dulaglutide in the treatment of type 2 diabetes: a comprehensive review of the dulaglutide clinical data focusing on the AWARD phase 3 clinical trial program. Diabetes Metab Res Rev 2016; 32:776-790. [PMID: 27102969 DOI: 10.1002/dmrr.2810] [Citation(s) in RCA: 95] [Impact Index Per Article: 11.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2015] [Revised: 03/18/2016] [Accepted: 04/13/2016] [Indexed: 01/24/2023]
Abstract
Dulaglutide (DU) is a once weekly glucagon-like peptide-1 receptor agonist (GLP-1 RA) approved for the treatment of type 2 diabetes mellitus (T2DM). Glycaemic efficacy and safety characteristics of dulaglutide have been assessed in six Phase 3 studies in the AWARD program. The objective of this review article is to summarize these results from the six completed AWARD studies. At the primary endpoint, in five of the six studies, once weekly dulaglutide 1.5 mg was superior to the active comparator [exenatide, insulin glargine (two studies), metformin, and sitagliptin], with a greater proportion of patients reaching glycated hemoglobin A1c (HbA1c) targets of <7.0% (53.0 mmol/mol) and ≤6.5% (47.5 mmol/mol). Dulaglutide 1.5 mg was non-inferior to liraglutide in AWARD-6. Once weekly dulaglutide 0.75 mg was evaluated in five of these trials and demonstrated superiority to the active comparator in four of five AWARD studies (exenatide, glargine, metformin, and sitagliptin), and non-inferiority to glargine in the AWARD-2 study. Similar to other GLP-1 receptor agonists, treatment with dulaglutide was associated with weight loss or attenuation of weight gain and low rates of hypoglycaemia when used alone or with non-insulin-secretagogue therapy. The most frequently reported adverse events were gastrointestinal, including nausea, vomiting, and diarrhea. The incidence of dulaglutide antidrug antibody formation was 1-2.8% with rare injection site reactions. In conclusion, dulaglutide is an effective treatment for T2DM and has an acceptable tolerability and safety profile. Copyright © 2016 John Wiley & Sons, Ltd.
