J Clin Endocrinol Metab 2024; 109:1745-1753. [PMID: 38252888 PMCID: PMC11180500 DOI: 10.1210/clinem/dgae038] [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: 10/25/2023] [Revised: 01/04/2024] [Accepted: 01/18/2024] [Indexed: 01/24/2024]
Abstract
CONTEXT In previous SURPASS studies tirzepatide reduced hemoglobin glycated A1c (HbA1c) and body weight and improved markers of insulin sensitivity and β-cell function to a greater extent than comparators. 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.

Abstract
AIMS The MIRAGE study aimed to evaluate the real-world use of once weekly (OW) subcutaneous semaglutide in glucagon-like peptide-1 receptor agonist naïve type 2 diabetes patients in routine clinical practice in North Macedonia. METHODS MIRAGE was a multicentre, single-arm, retrospective and 30-weeks study, conducted in North Macedonia. Primary [change in glycated haemoglobin (HbA1c)] and secondary endpoints [change in body weight, fasting plasma glucose (FPG), lipid parameters, blood pressure, waist circumference, glycaemic and weight-loss target achievement] were evaluated between baseline and end of study (EOS). RESULTS Baseline characteristics of 314 patients enrolled in the study were, mean age: 55.5 years, HbA1c: 9.0 %, diabetes duration: 7.8 years, body weight: 105.2 kg and waist circumference: 114 cm. Patients at EOS experienced statistically significant estimated mean change in HbA1c: -2.2 % points, body weight: -9.0 kg, and FPG: -4.1 mmol/L (all p < 0.0001). At EOS, 62.1 % patients achieved HbA1c < 7 %, and 79.3 % had ≥ 1 % HbA1c reduction. A weight reduction of ≥ 3 % and ≥ 5 % was noted in 88.3 % and 73.3 % patients, respectively. No new safety concern has emerged. CONCLUSIONS Findings from MIRAGE study demonstrated glycaemic and weight-loss benefits of semaglutide, with improvements in other cardiometabolic parameters. The study supports real-world OW subcutaneous semaglutide use in North Macedonia.

Abstract
BACKGROUND To compare glycemic control in Chinese patients with type 2 diabetes mellitus (T2DM) whose blood glucose levels were inadequately controlled with oral antidiabetic drugs after beinaglutide alone or combined with insulin glargine (IGlar). METHODS In this 16-week multicenter, randomized clinical trial, 68 participants randomly received beinaglutide or IGlar for 8 weeks, then the two drugs in combination for 8 weeks. The primary outcomes were the proportion of individuals achieving their glycemic target and the change in glucose variability as measured with a continuous glucose monitoring system from baseline to 8 and 16 weeks. RESULTS Both the beinaglutide and IGlar groups showed increased proportions achieving their glycemic target at 8 weeks, and the combination augmented the proportion reaching the glycated hemoglobin target from 25.42% at 8 weeks to 40.68% at 16 weeks. The beinaglutide group showed a significant reduction in body weight, body mass index, waist circumference, and systolic blood pressure. Beinaglutide elevated high-density lipoprotein cholesterol by 0.08 mmol/L (95% confidence interval [CI], 0.00-0.16), and diminished low-density lipoprotein cholesterol by 0.21 mmol/L (95% CI, 0.05-0.48), whereas IGlar showed no effect. Though IGlar was more efficient in lowering fasting plasma glucose than beinaglutide at comparable efficacies (to -1.57 mmol/L [95% CI, -2.60 to -0.54]), this difference was abolished in patients whose fasting C-peptide was ≥0.9 ng/mL. CONCLUSION Beinaglutide exhibited a favorable hypoglycemic effect on patients with T2DM, and in combination with IGlar, glucose level was further decreased. Low fasting C-peptide in patients may reduce the glycemic response to beinaglutide therapy. We recommend that C-peptide levels be evaluated when using or switching to the novel glucagon-like peptide-1 receptor agonists beinaglutide. TRIAL REGISTRATION ClinicalTrials.gov: NCT03829891.

Abstract
AIMS To understand glucagon-like peptide-1 receptor agonist (GLP-1RA) use in patients with type 2 diabetes (T2D) in Japan. METHODS Characteristics of people receiving GLP-1RAs between 2016 and 2020 in the J-DREAMS database were investigated. Changes in HbA1c, body weight (BW), body mass index (BMI), and proportion reaching HbA1c targets were analysed in GLP-1RA-naïve patients 6-24 months after GLP-1RA initiation. RESULTS The proportion of patients with GLP-1RA prescriptions increased from 3.6% to 9.6% during 2016-2020. Among GLP-1RA-naïve patients (n = 569), HbA1c reduced -0.6% (95% confidence interval [CI] -0.7, -0.5; -6 mmol/mol [95% CI -7, -5]) 6 months after treatment initiation and stabilised until 24 months (P < 0.001); mean BW and BMI reduced -1.05 kg (95% CI -1.31, -0.80) and -0.43 kg/m2 (95% CI -0.53, -0.32), respectively, at 6 months (P < 0.001). The proportion of GLP-1RA-naïve patients with HbA1c < 7.0% (<53 mmol/mol) and <8.0% (<64 mmol/mol) increased from 16% to 27% and 43% to 65%, respectively, and an HbA1c reduction of ≥1.0% (≥11 mmol/mol) was observed in 33% of patients after 6 months (P < 0.001). CONCLUSIONS This study shows increased GLP-1RA prescriptions over 5 years. HbA1c and BW reduced 6 months after GLP-1RA initiation in patients with T2D in a Japanese real-world setting.

Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are widely used to address multiple aspects of type 2 diabetes mellitus (T2DM) management, including glycaemic control, weight loss, and cardiovascular risk reduction. Semaglutide, a well-established GLP-1 RA approved for T2DM treatment and weight management, demonstrates marked efficacy in achieving these clinically important goals. The American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) consensus report emphasizes the importance of a holistic approach to T2DM treatment, with weight control as a key component for improving patient outcomes. Notably, semaglutide is mentioned in the consensus report as having 'very high' efficacy for both glucose lowering and weight loss in T2DM treatment. Nevertheless, as has been observed with other weight-lowering drugs, weight loss observed with semaglutide appears less profound in individuals with T2DM than in those with obesity without T2DM, a phenomenon requiring further investigation. The semaglutide safety and tolerability profiles are well established, and it is approved in some countries to reduce cardiovascular risk in certain populations with T2DM. Thus, semaglutide offers a well-established therapeutic option that aligns well with guideline recommendations for T2DM management, emphasizing the high importance of weight control and amelioration of other cardiometabolic risk factors.

Effect of Semaglutide on Subclinical Atherosclerosis and Cardiometabolic Compensation: A Real-World Study in Patients with Type 2 Diabetes. Biomedicines 2023; 11:biomedicines11051362.

Abstract
BACKGROUND Semaglutide is a recently approved glucagon-like peptide-1 receptor agonist. Several trials reported the protective effect of injectable semaglutide on cardiovascular (CV) risk by reducing major adverse cardiovascular events in type 2 diabetes patients. Strong preclinical evidence supports the CV benefits of semaglutide through an effect on atherosclerosis. However, scant evidence is available about the protective mechanisms of semaglutide in clinical practice. METHODS A retrospective observational study was conducted among consecutive type 2 diabetes patients treated with injectable semaglutide in Italy between November 2019 and January 2021 when the drug was first available in the country. The primary aims were the assessment of the carotid intima-media thickness (cIMT) and hemoglobin A1c (HbA1c) levels. The secondary aims were the evaluation of anthropometric, glycemic, and hepatic parameters and plasma lipids, including the assessment of the triglyceride/high-density lipoprotein ratio as an indirect marker of atherogenic small, dense low-density lipoprotein particles. RESULTS Injectable semaglutide reduced HbA1c and cIMT. An improvement in CV risk factors and the triglyceride/high-density lipoprotein ratio was reported. Moreover, through correlation analyses, we found that hepatic fibrosis and steatosis indices and the anthropometric, hepatic, and glycemic parameters, as well as plasma lipids, were unrelated to the variations in cIMT and HbA1c. CONCLUSIONS Our findings suggest the effect of injectable semaglutide on atherosclerosis as a key CV protective mechanism. Considering the favorable effects on atherogenic lipoproteins and hepatic steatosis indices, our results support the pleiotropic effect of semaglutide beyond glycemic control.

Abstract
INTRODUCTION This analysis investigated the efficacy and safety of add-on lixisenatide by disease duration in Asian people with type 2 diabetes inadequately controlled with basal insulin ± oral antidiabetic drugs. METHODS Data for Asian participants in the GetGoal-Duo 1, GetGoal-L, and GetGoal-L-C studies were pooled and categorized by diabetes duration: < 10 years (group 1), 10 to < 15 years (group 2), and ≥ 15 years (group 3). Efficacy and safety of lixisenatide versus placebo were evaluated by subgroup. The potential influence of diabetes duration on efficacy was examined using multivariable regression analyses. RESULTS A total of 555 participants were included (mean age 53.9 years, 52.4% male). No significant differences in treatment effect between the duration subgroups were observed for the changes from baseline to 24 weeks in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), postprandial glucose (PPG), PPG excursion, body weight or body mass index, or the proportion of participants with HbA1c < 7% at 24 weeks (all P values for interaction > 0.1). Change in insulin dosage (U/day) was significantly different between subgroups (P = 0.038). Multivariable regression analysis showed participants in group 1 had a smaller change in body weight and basal insulin dose over the 24-week treatment period than participants in group 3 (P = 0.014 and 0.030, respectively) and were less likely to achieve an HbA1c < 7% than participants in group 2 (P = 0.047). No severe hypoglycemia was reported. A higher proportion of participants in group 3 versus the other groups had symptomatic hypoglycemia, for both lixisenatide and placebo, and T2D duration had a significant effect on hypoglycemia risk (P = 0.001). CONCLUSIONS Lixisenatide improved glycemic control in Asian individuals regardless of diabetes duration, without increasing the risk of hypoglycemia. Individuals with longer disease duration had a greater risk of symptomatic hypoglycemia than individuals with shorter disease duration regardless of treatment. No additional safety concerns were observed.

Abstract
Early and intensive management of type 2 diabetes has been shown to delay disease progression, reduce the risk of cardiorenal complications and prolong time to treatment failure. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are being increasingly recognized for their potential in early disease management, with recent guideline updates recommending second-line use of this injectable drug class alongside oral glucose-lowering drugs. GLP-1RAs target at least six of the eight core defects implicated in the pathogenesis of type 2 diabetes and offer significant glycaemic and weight-related improvements over other second-line agents in head-to-head trials. In addition, placebo-controlled clinical trials have shown cardiovascular protection with GLP-1RA use. Even so, this therapeutic class is underused in primary care, largely owing to clinical inertia and patient-related barriers to early intensification with GLP-1RAs. Fortunately, clinicians can overcome barriers to treatment acceptance through patient education and training, and management of treatment expectations. In this review we comment on global and Australian guideline updates and evidence in support of early intensification with this therapeutic class, and provide clinicians with practical advice for GLP-1RA use in primary care.

Abstract
Impaired beta-cell function is a recognized cornerstone of diabetes pathophysiology. Estimates of insulin secretory capacity are useful to inform clinical practice, helping to classify types of diabetes, complication risk stratification and to guide treatment decisions. Because C-peptide secretion mirrors beta-cell function, it has emerged as a valuable clinical biomarker, mainly in autoimmune diabetes and especially in adult-onset diabetes. Nonetheless, the lack of robust evidence about the clinical utility of C-peptide measurement in type 2 diabetes, where insulin resistance is a major confounder, limits its use in such cases. Furthermore, problems remain in the standardization of the assay for C-peptide, raising concerns about comparability of measurements between different laboratories. To approach the heterogeneity and complexity of diabetes, reliable, simple and inexpensive clinical markers are required that can inform clinicians about probable pathophysiology and disease progression, and so enable personalization of management and therapy. This review summarizes the current evidence base about the potential value of C-peptide in the management of the two most prevalent forms of diabetes (type 2 diabetes and autoimmune diabetes) to address how its measurement may assist daily clinical practice and to highlight current limitations and areas of uncertainties to be covered by future research.

Abstract
PURPOSE Registered trials and real-world evidence (RWE) studies provided evidence on the efficacy of once-weekly (OW) semaglutide on hyperglycaemia and cardiovascular risk factors as add-on or de-novo treatment in type 2 diabetes (T2D). METHODS In a retrospective analysis of electronic data files from 258 T2D patients, this RWE study aimed to explore the impact of OW semaglutide on biochemical and anthropometric outcomes after 6 and 12 months in patients receiving at least one prescription of OW semaglutide between September 2019 and May 2021. RESULTS During the study period, 154 and 56 consecutive patients completed the 6 and 12 months of OW semaglutide treatment. HbA1c levels decreased by -1.02±0.1% after 6 months and -1.1±0.1% after 12 months of OW semaglutide (p<0.0001 for both). At these time-points, HbA1c values were <7% in 61% and 57% of cases. HbA1c reduction was greater in patients with higher baseline HbA1c levels and it occurred irrespective of gender, age, insulin therapy and complications. The residual number of cases with HbA1c ≥9% by the study end was low (5.3% vs 18.9% at baseline). Weight loss occurred in 73.5% and 78.1% of cases and, compared to baseline, it was ≥5% in 21.2- 25.4% and ≥10% in 6.8-18.2% after 6 and 12 months, respectively. Significant predictors of HbA1c reduction after 6 months of OW semaglutide treatment were baseline HbA1c (p<0.0001), bodyweight reduction (p<0.0001) and disease duration (p<0.001), while baseline HbA1c was the only predictor of HbA1c response after 12 months (p<0.0001). Reported adverse events were consistent with the known safety profile of semaglutide. CONCLUSIONS Real-world evaluation of weekly subcutaneous treatment with semaglutide in a cohort of Italian diabetic patients.

Efficacy and safety of oral semaglutide by subgroups of patient characteristics in the PIONEER phase 3 programme. Diabetes Obes Metab 2022; 24:1338-1350. [PMID: 35373893 PMCID: PMC9321749 DOI: 10.1111/dom.14710] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 03/29/2022] [Accepted: 03/30/2022] [Indexed: 11/30/2022]
Abstract
AIMS To evaluate the efficacy and safety of oral semaglutide versus comparators by patient characteristic subgroups in patients with type 2 diabetes. MATERIALS AND METHODS Change from baseline in glycated haemoglobin (HbA1c) and body weight, and achievement of HbA1c <7.0% with oral semaglutide 7 mg, oral semaglutide 14 mg, flexibly dosed oral semaglutide (flex) and comparators were assessed across baseline subgroups (age, race, ethnicity, diabetes duration, body mass index and HbA1c) from the PIONEER programme. Treatment differences were analysed using a mixed model for repeated measurements for continuous variables and a logistic regression model for the binary endpoint. Pooled safety data were analysed descriptively. RESULTS Changes from baseline in HbA1c and body weight, and the odds of achieving HbA1c <7.0%, were greater with oral semaglutide 14 mg/flex (n = 1934) and higher or similar with oral semaglutide 7 mg (n = 823) versus comparators (n = 2077) across most subgroups. Changes in HbA1c with oral semaglutide 14 mg/flex were greater for patients with higher baseline HbA1c (HbA1c >9.0%: -1.7% to -2.6%; HbA1c <8.0%: -0.7% to -1.2%). In some trials, Asian patients experienced greater HbA1c reductions with oral semaglutide 14 mg/flex (-1.5% to -1.8%) than other racial groups (-0.6% to -1.6%). The overall incidence of adverse events (AEs) with oral semaglutide was similar to that with comparators and was consistent across subgroups. More gastrointestinal AEs were observed with oral semaglutide, versus comparators, across subgroups. CONCLUSIONS Oral semaglutide demonstrated consistently greater HbA1c and body weight reductions across a range of patient characteristics, with greater HbA1c reductions seen at higher baseline HbA1c levels.

Abstract
Aims/Introduction To assess the impact of baseline characteristics on the efficacy and safety of oral semaglutide in Japanese patients with type 2 diabetes. Materials and Methods In the Peptide InnOvatioN for Early diabEtes tReatment (PIONEER) 9 and 10 trials, Japanese patients were randomized to once‐daily oral semaglutide (3, 7, or 14 mg) or a comparator (placebo or once‐daily subcutaneous liraglutide 0.9 mg in PIONEER 9; once‐weekly subcutaneous dulaglutide 0.75 mg in PIONEER 10) for 52 weeks, with 5 weeks of follow up. An exploratory analysis grouped patients in each trial according to baseline glycated hemoglobin (HbA1c; ≤8.0, >8.0–≤9.0, or >9.0%), body mass index (<25, ≥25–<30, or ≥30 kg/m2) and, for PIONEER 10 only, by background medication (sulfonylurea, glinide, thiazolidinedione, α‐glucosidase inhibitor, sodium‐glucose cotransporter 2 inhibitor). Efficacy (changes from baseline to week 26 in HbA1c and bodyweight) and safety were assessed. Results Seven hundred and one patients were included (PIONEER 9: N = 243; PIONEER 10: N = 458). In both trials, HbA1c reductions increased as baseline HbA1c increased; there were no other apparent patterns between the variables investigated and HbA1c or bodyweight changes. There was one statistically significant subgroup interaction between baseline HbA1c and estimated treatment differences in bodyweight change for oral semaglutide 14 mg versus placebo in PIONEER 9 (P = 0.0286). Baseline HbA1c, baseline body mass index and background medication did not appear to affect the proportions of patients reporting adverse events. Conclusions Oral semaglutide is effective across a range of baseline subgroups of Japanese patients with type 2 diabetes, with no unexpected safety findings.

Abstract
AIM To evaluate the impact of dulaglutide 3.0 and 4.5 mg versus 1.5 mg on body weight in patients with type 2 diabetes (T2D) based on exploratory analyses of the AWARD-11 trial. MATERIALS AND METHODS Patients were randomized to once-weekly dulaglutide 1.5 (n = 612), 3.0 (n = 616) or 4.5 mg (n = 614) for 52 weeks. The primary objective was superiority of dulaglutide 3.0 and/or 4.5 mg over 1.5 mg in HbA1c reduction at 36 weeks. Secondary and exploratory assessments included weight reduction in the overall trial population and baseline body mass index (BMI) and HbA1c subgroups. RESULTS At baseline, patients had a mean age of 57.1 years, HbA1c 8.6% (70 mmol/mol), weight 95.7 kg and BMI 34.2 kg/m2 . At 36 weeks, dulaglutide 3.0 and 4.5 mg were superior to 1.5 mg for weight change from baseline (1.5 mg, -3.1 kg; 3.0 mg, -4.0 kg [P = .001]; 4.5 mg, -4.7 kg [P < .001]). Higher dulaglutide doses were associated with numerically greater weight reduction compared with 1.5 mg in each baseline BMI and HbA1c subgroup. Absolute weight reduction increased with increasing BMI category, but percentage weight loss was similar between subgroups. Weight reductions with dulaglutide were greater in patients with lower versus higher baseline HbA1c. CONCLUSIONS In patients with T2D, inadequately controlled by metformin, incremental weight loss was observed with dulaglutide 1.5, 3.0 and 4.5 mg doses regardless of baseline BMI or HbA1c. Although absolute weight loss was numerically greater in patients with higher baseline BMI, percentage of weight loss was similar between BMI subgroups.

Diabetes Obes Metab 2021; 23:2234-2241. [PMID: 34132018 PMCID: PMC8518913 DOI: 10.1111/dom.14464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 05/28/2021] [Accepted: 06/09/2021] [Indexed: 11/29/2022]
Abstract
AIMS The LIRA-ADD2SGLT2i trial demonstrated that liraglutide + sodium-glucose cotransporter-2 inhibitors (SGLT2is) ± metformin significantly improved glycaemic control (not body weight) versus placebo in adults with type 2 diabetes (T2D). This post-hoc analysis assessed whether baseline characteristics influenced these findings. MATERIALS AND METHODS LIRA-ADD2SGLT2i (NCT02964247) was a placebo-controlled, double-blind, multinational trial, wherein participants received liraglutide (≤1.8 mg/day) or placebo (randomized 2:1). Changes from baseline to week 26 in haemoglobin A1c (HbA1c), body weight and waist circumference stratified by HbA1c, body mass index (BMI), diabetes duration, duration of pre-trial SGLT2i use and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) were analysed. These five baseline characteristics were divided into tertiles, and the treatment effect was evaluated using the trial product estimand. RESULTS Data from all 303 participants were analysed. There was a significant interaction between baseline HbA1c tertiles (7.0%-<7.6%; 7.6%-8.1%; ≥8.2%-9.5%) and glycaemic control at week 26 (p[interaction] = .011), with the lowest HbA1c estimated treatment difference (95% confidence interval) observed in patients with lowest baseline HbA1c [-0.20% (-0.59, 0.19); -0.68% (-1.03, -0.33); -0.98% (-1.33, -0.64), respectively]. There were no significant interactions in glycaemic control across baseline BMI, diabetes duration, insulin resistance determined by HOMA-IR or SGLT2i use duration (p[interaction] > .05, all). Across the five characteristics assessed, no significant interactions were found for body weight or waist circumference changes from baseline (p[interaction] > .05, all). CONCLUSION For individuals with T2D and inadequate glycaemic control despite therapy with SGLT2is ± metformin, liraglutide 1.8 mg would provide an effective treatment intensification option, irrespective of HbA1c, BMI, diabetes duration, insulin resistance determined by HOMA-IR and SGLT2i use duration.

Lancet Diabetes Endocrinol 2021; 9:563-574. [PMID: 34293304 DOI: 10.1016/s2213-8587(21)00174-1] [Citation(s) in RCA: 83] [Impact Index Per Article: 27.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 06/11/2021] [Accepted: 06/14/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND Semaglutide is an effective treatment for type 2 diabetes; however, 20-30% of patients given semaglutide 1·0 mg do not reach glycaemic treatment goals. We aimed to investigate the efficacy and safety of once-weekly semaglutide 2·0 mg versus 1·0 mg in adults with inadequately controlled type 2 diabetes on a stable dose of metformin with or without a sulfonylurea. METHODS We did a 40-week, randomised, active-controlled, parallel-group, double-blind, phase 3B trial (SUSTAIN FORTE) at 125 outpatient clinics in ten countries. Participants (≥18 years) with inadequately controlled type 2 diabetes (HbA1c 8·0-10·0%) with metformin and with or without sulfonylurea were randomly assigned (1:1) by an interactive web-response system to 2·0 mg or 1·0 mg once-weekly semaglutide. Participants, site personnel, the clinical study group, and investigators were masked to the randomised treatment. Outcomes included change from baseline at week 40 in HbA1c (primary outcome) and bodyweight (secondary confirmatory outcome), evaluated through trial product estimand (no treatment discontinuation or without rescue medication) and treatment policy estimand (regardless of treatment discontinuation or rescue medication) strategies. This study is registered with ClinicalTrials.gov, NCT03989232; EudraCT, 2018-004529-96; and WHO, U1111-1224-5162. FINDINGS Between June 19 and Nov 28, 2019, of 1515 adults assessed for eligibility, 961 participants (mean age 58·0 years [SD 10·0]; 398 [41%] women) were included. Participants were randomly assigned to once-weekly semaglutide 2·0 mg (n=480 [50%]) or 1·0 mg (n=481 [50%]); 462 (96%) patients in the semaglutide 2·0 mg group and 471 (98%) in the semaglutide 1·0 mg group completed the trial. Mean baseline HbA1c was 8·9% (SD 0·6; 73·3 mmol/mol [SD 6·9]) and BMI was 34·6 kg/m2 (SD 7·0). Mean change in HbA1c from baseline at week 40 was -2·2 percentage points with semaglutide 2·0 mg and -1·9 percentage points with semaglutide 1·0 mg (estimated treatment difference [ETD] -0·23 percentage points [95% CI -0·36 to -0·11]; p=0·0003; trial product estimand) and -2·1 percentage points with semaglutide 2·0 mg and -1·9 percentage points with semaglutide 1·0 mg (ETD -0·18 percentage points [-0·31 to -0·04]; p=0·0098; treatment policy estimand). Mean change in bodyweight from baseline at week 40 was -6·9 kg with semaglutide 2·0 mg and -6·0 kg with semaglutide 1·0 mg (ETD -0·93 kg [95% CI -1·68 to -0·18]; p=0·015; trial product estimand) and -6·4 kg with semaglutide 2·0 mg and -5·6 kg with semaglutide 1·0 mg (ETD -0·77 kg [-1·55 to 0·01]; p=0·054; treatment policy estimand). Gastrointestinal disorders were the most commonly reported adverse events (163 [34%] in the 2·0 mg group and 148 [31%] in the 1·0 mg group). Serious adverse events were similar between treatment groups, reported for 21 (4%) participants given semaglutide 2·0 mg and 25 (5%) participants given semaglutide 1·0 mg. Three deaths were reported during the trial (one in the semaglutide 1·0 mg group and two in the semaglutide 2·0 mg group). INTERPRETATION Semaglutide 2·0 mg was superior to 1·0 mg in reducing HbA1c, with additional bodyweight loss and a similar safety profile. This higher dose provides a treatment intensification option for patients with type 2 diabetes treated with semaglutide in need of additional glycaemic control. FUNDING Novo Nordisk.

Abstract
AIM To evaluate the impact of relevant patient-level characteristics on the efficacy and safety of subcutaneous, once-weekly semaglutide in subjects with type 2 diabetes. MATERIALS AND METHODS Exploratory post hoc analyses of pooled SUSTAIN 1-5 (phase 3a) randomized, controlled trials examined the change from baseline in HbA1c and body weight (BW), and the proportions of subjects achieving the composite endpoint (HbA1c < 7.0% [53 mmol/mol]), without weight gain or severe/blood glucose-confirmed symptomatic hypoglycaemia at week 30 with semaglutide (0.5/1.0 mg) across clinically relevant patient subgroups: baseline HbA1c (≤7.5%, >7.5%-8.0%, >8.0%-8.5%, >8.5%-9.0% and > 9.0%), background medications, diabetes duration and pancreatic beta-cell function. RESULTS Mean HbA1c (% point) reductions increased from lowest to highest HbA1c subgroups (-0.9%, -1.2%,-1.5%, -1.7% and -2.3% [effect of subgroup within treatment: P = 0.247] for semaglutide 0.5 mg, and -1.1%, -1.4%, -1.9%, -2.1% and -2.7% [P = 0.045] for semaglutide 1.0 mg), with mean HbA1c ranges at week 30 of 6.3%-7.3% and 6.1%-6.9%, respectively. The corresponding BW reductions generally decreased with increasing baseline HbA1c (-4.4, -3.9, -3.9, -3.3 and -2.9 kg [P = 0.004], and -6.4, -5.9, -5.2, -4.5 and -4.8 kg [P < 0.001], respectively). HbA1c and BW reductions were consistently greater for semaglutide 1.0 mg versus 0.5 mg across background medication, diabetes duration and pancreatic beta-cell function subgroups. Adverse events with semaglutide were consistent with the glucagon-like peptide-1 receptor agonist class, with gastrointestinal events the most common. CONCLUSIONS Semaglutide was consistently efficacious across the continuum of diabetes care in a broad spectrum of patient subgroups with a range of clinical characteristics.
