Once-weekly IcoSema versus once-weekly semaglutide in adults with type 2 diabetes: the COMBINE 2 randomised clinical trial.

COMBINE 2 assessed the efficacy and safety of once-weekly IcoSema (a combination therapy of basal insulin icodec and semaglutide) vs once-weekly semaglutide (a glucagon-like peptide-1 analogue) 1.0 mg in individuals with type 2 diabetes inadequately managed with GLP-1 receptor agonist (GLP-1 RA) therapy, with or without additional oral glucose-lowering medications. This 52 week, randomised, multicentre, open-label, parallel group, Phase IIIa trial was conducted across 121 sites in 13 countries/regions. Adults with type 2 diabetes (HbA1c 53.0-85.8 mmol/mol [7.0-10.0%]) receiving GLP-1 RA therapy with or without additional oral glucose-lowering medications were randomly assigned 1:1 to once-weekly IcoSema or once-weekly semaglutide 1.0 mg. The primary endpoint was change in HbA1c from baseline to week 52; superiority of IcoSema to semaglutide 1.0 mg was assessed. Secondary endpoints included change in fasting plasma glucose and body weight (baseline to week 52), and combined clinically significant (level 2; <3.0 mmol/l) or severe (level 3; associated with severe cognitive impairment requiring external assistance for recovery) hypoglycaemia (baseline to week 57). Overall, 683 participants were randomised using a Randomisation and Trial Supply Management system to IcoSema (n=342) or semaglutide 1.0 mg (n=341). Mean ± SD baseline characteristics were as follows: HbA1c 64.0±8.2 mmol/mol (8.0±0.7%); diabetes duration 12.6±6.9 years; and BMI 31.1±4.7 kg/m2. From baseline to week 52, mean change in HbA1c was -14.7 mmol/mol (-1.35%-points) in the IcoSema group and -9.88 mmol/mol (-0.90%-points) in the semaglutide group; the estimated treatment difference (ETD) was -4.85 (95% CI -6.13, -3.57) mmol/mol (-0.44 [95% CI -0.56, -0.33]%-points), confirming superiority of IcoSema to semaglutide (p<0.0001). The estimated mean change in fasting plasma glucose from baseline to week 52 was statistically significantly reduced with IcoSema vs semaglutide (-2.48 mmol/l vs -1.43 mmol/l, respectively; ETD -1.05 [95% CI -1.36, -0.75] mmol; p<0.0001). Mean change in body weight from baseline to week 52 was statistically significantly different between groups: +0.84 kg for IcoSema vs -3.70 kg for semaglutide (ETD 4.54 kg [95% CI 3.84, 5.23]; p<0.0001). There was no statistically significant difference in the rate of combined clinically significant or severe hypoglycaemia between IcoSema and semaglutide (0.042 vs 0.036 episodes per person-year of exposure; estimated rate ratio 1.20 [95% CI 0.53, 2.69]; p=0.66). The proportion of participants experiencing gastrointestinal adverse events was similar between treatment groups (IcoSema 31.4%; semaglutide 34.4%). In people living with type 2 diabetes inadequately managed with GLP-1 RA therapy, with or without additional oral glucose-lowering medications, switching to once-weekly IcoSema in comparison with once-weekly semaglutide 1.0 mg demonstrated superiority in HbA1c reduction, similar rates of clinically significant or severe hypoglycaemia, and similar frequency of gastrointestinal adverse events. However, weight change from baseline to week 52 was statistically significantly in favour of semaglutide 1.0 mg. ClinicalTrials.gov NCT05259033 FUNDING: This trial was funded by Novo Nordisk.

Efficacy and safety of oral semaglutide monotherapy vs placebo in a predominantly Chinese population with type 2 diabetes (PIONEER 11): a double-blind, Phase IIIa, randomised trial.

The aim of this study was to evaluate the efficacy and safety of oral semaglutide monotherapy vs placebo in a predominantly Chinese population with type 2 diabetes insufficiently controlled with diet and exercise alone. The Peptide Innovation for Early Diabetes Treatment (PIONEER) 11 trial was a double-blind, randomised, Phase IIIa trial conducted across 52 sites in the China region (mainland China and Taiwan), Hungary, Serbia and Ukraine. Eligible participants were ≥18 years (≥20 years in Taiwan), had a diagnosis of type 2 diabetes with HbA1c 53-86 mmol/mol (7.0-10.0%) and were not receiving any glucose-lowering drugs. After a 4-week run-in period in which participants were treated with diet and exercise alone, those who fulfilled the randomisation criteria were randomised (1:1:1:1) using a web-based randomisation system to receive once-daily oral semaglutide 3 mg, 7 mg or 14 mg or placebo for 26 weeks (using a 4-week dose-escalation regimen for the higher doses). Randomisation was stratified according to whether participants were from the China region or elsewhere. The primary and confirmatory secondary endpoints were change from baseline to week 26 in HbA1c and body weight (kg), respectively. Safety was assessed in all participants exposed to at least one dose of the trial product. Between October 2019 and October 2021, a total of 774 participants were screened and 521 participants were randomised to oral semaglutide 3 mg (n=130), 7 mg (n=130), 14 mg (n=130) or placebo (n=131); most participants (92.5%, n=482) completed the trial, with 39 participants prematurely discontinuing treatment. The number of participants contributing to the trial analyses was based on the total number of participants who were randomised at the beginning of the trial. The majority of participants were male (63.7%), and the mean age of participants was 52 years. At baseline, mean HbA1c and body weight were 63 mmol/mol (8.0%) and 79.6 kg, respectively. Oral semaglutide resulted in significantly greater reductions in HbA1c than placebo at week 26 (p<0.001 for all doses). The estimated treatment differences (ETDs [95% CIs]) for oral semaglutide 3 mg, 7 mg and 14 mg vs placebo were -11 (-13, -9) mmol/mol, -16 (-18, -13) mmol/mol and -17 (-19, -15) mmol/mol, respectively. The corresponding ETDs in percentage points (95% CI) vs placebo were -1.0 (-1.2, -0.8), -1.4 (-1.6, -1.2) and -1.5 (-1.8, -1.3), respectively. Significantly greater reductions in body weight were also observed for oral semaglutide 7 mg and 14 mg than for placebo at week 26 (ETD [95% CI] -1.2 kg [-2.0 kg, -0.4 kg; p<0.01] and -2.0 kg [-2.8 kg, -1.2 kg; p<0.001], respectively), but not for oral semaglutide 3 mg (ETD [95% CI] -0.0 kg [-0.9 kg, 0.8 kg; not significant]). Similar reductions in HbA1c and body weight were observed in the Chinese subpopulation, which represented 74.9% of participants in the overall population. Adverse events (AEs) occurred in between 65.4% and 72.3% of participants receiving oral semaglutide (for all doses) and 57.3% of participants with placebo. Most AEs were mild to moderate in severity, with few serious AEs reported; the most commonly reported AEs were gastrointestinal-related and were more frequent with semaglutide (all doses) than with placebo. The proportion of AEs was slightly higher in the Chinese subpopulation. Oral semaglutide resulted in significantly greater reductions in HbA1c across all doses and in significant body weight reductions for the 7 mg and 14 mg doses when compared with placebo in predominantly Chinese participants with type 2 diabetes insufficiently controlled by diet and exercise alone. Oral semaglutide was generally well tolerated, with a safety profile consistent with that seen in the global PIONEER trials. ClinicalTrials.gov NCT04109547. Novo Nordisk A/S.

Efficacy and safety of oral semaglutide vs sitagliptin in a predominantly Chinese population with type 2 diabetes uncontrolled with metformin: PIONEER 12, a double-blind, Phase IIIa, randomised trial.

The aim of this study was to assess the efficacy and safety of oral semaglutide vs sitagliptin in a predominantly Chinese population with type 2 diabetes inadequately controlled with metformin treatment. The Peptide Innovation for Early Diabetes Treatment (PIONEER) 12 trial was a randomised, double-dummy, active-controlled, parallel-group, Phase IIIa trial conducted over 26 weeks at 90 sites across the China region (including mainland China, Taiwan and Hong Kong) and five other countries. Adults aged ≥18 years (≥20 years in Taiwan) with a diagnosis of type 2 diabetes, HbA1c between 53 and 91 mmol/mol (inclusive) and treated with a stable daily dose of metformin were eligible for inclusion. Participants were randomised (1:1:1:1) using a web-based randomisation system to either once-daily oral semaglutide (3 mg, 7 mg or 14 mg) or once-daily oral sitagliptin 100 mg. Treatment allocation was masked to both participants and investigators. Randomisation was stratified according to whether participants were from the China region or elsewhere. The primary endpoint was change in HbA1c from baseline to week 26. The confirmatory secondary endpoint was change in body weight (kg) from baseline to week 26. All randomised participants were included in the full analysis set (FAS). All participants exposed to at least one dose of trial product were included in the safety analysis (SAS). Of 1839 participants screened, 1441 were randomly assigned to oral semaglutide 3 mg (n=361), 7 mg (n=360), 14 mg (n=361) or sitagliptin 100 mg (n=359) and included in the FAS. A total of 1438 participants were included in the SAS. In total, 75.2% of participants were from the China region. A total of 1372 (95.2%) participants completed the trial and 130 participants prematurely discontinued treatment (8.3%, 8.6% and 15.0% for oral semaglutide 3 mg, 7 mg and 14 mg, respectively; 4.2% for sitagliptin 100 mg). Significantly greater reductions in HbA1c from baseline to week 26 were reported for all doses of oral semaglutide vs sitagliptin 100 mg. For oral semaglutide 3 mg, 7 mg and 14 mg vs sitagliptin 100 mg, the estimated treatment differences (ETDs [95% CI]) were -2 (-4, -1) mmol/mol, -8 (-9, -6) mmol/mol and -11 (-12, -9) mmol/mol, respectively. The corresponding ETDs (95% CI) in percentage points vs sitagliptin 100 mg were -0.2 (-0.3, -0.1), -0.7 (-0.8, -0.6) and -1.0 (-1.1, -0.8), respectively. Reductions in body weight were significantly greater for all doses of oral semaglutide vs sitagliptin 100 mg (ETD [95% CI] -0.9 [-1.4, -0.4] kg, -2.3 [-2.8, -1.8] kg and -3.3 [-3.8, -2.8] kg for 3 mg, 7 mg and 14 mg, respectively). In the subpopulation of participants from the China region (75.2% of trial participants), reductions in HbA1c and body weight from baseline to week 26 were similar to those seen in the overall population. The most frequent adverse events in the semaglutide treatment arms were gastrointestinal, although these were mostly transient and mild/moderate in severity. Significantly greater reductions in both HbA1c and body weight over 26 weeks were seen with oral semaglutide 3 mg, 7 mg and 14 mg than with sitagliptin 100 mg in a predominantly Chinese population with type 2 diabetes inadequately controlled with metformin treatment. Oral semaglutide was generally well tolerated, with a safety profile consistent with that seen in the global PIONEER trials. ClinicalTrials.gov NCT04017832.

Efficacy and safety of once-weekly semaglutide 2·4 mg versus placebo in people with obesity and prediabetes (STEP 10): a randomised, double-blind, placebo-controlled, multicentre phase 3 trial.

There are currently limited data regarding the effect of semaglutide 2·4 mg in individuals with obesity and prediabetes in clinical trials. We aimed to assess the efficacy and safety of semaglutide 2·4 mg for weight management and glycaemic control in participants with obesity and prediabetes. STEP 10 was a randomised, double-blind, parallel-group, phase 3 trial done across 30 trial sites in Canada, Denmark, Finland, Spain, and the UK and included participants aged 18 years or older with a BMI of 30 kg/m2 or higher and prediabetes according to UK National Institute for Health and Care Excellence criteria (defined as having at least one of the following at screening: HbA1c of 6·0-6·4% [42-47 mmol/mol] or fasting plasma glucose [FPG] of 5·5-6·9 mmol/L). Participants were randomly assigned (2:1) to once-weekly subcutaneous semaglutide 2·4 mg or placebo with diet and physical activity counselling for 52 weeks, followed by a 28-week off-treatment period. Primary endpoints were percentage change in bodyweight and proportion of participants reverting to normoglycaemia (HbA1c <6·0% [<42 mmol/mol] and FPG <5·5 mmol/L) at week 52 (assessed in all randomly assigned participants by intention to treat). Selective safety data were collected for participants who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, NCT05040971, and is complete. Between Sept 16 and Dec 29, 2021, 138 participants were randomly assigned to semaglutide 2·4 mg and 69 to placebo. 147 (71%) were female and 60 (29%) were male; 183 (88%) were White. All randomly assigned participants received at least one dose of study drug. Baseline mean age was 53 years (SD 11), bodyweight 111·6 kg (22·2), BMI 40·1 kg/m2 (6·9), waist circumference 120·1 cm (14·7), HbA1c 5·9% (0·3; 41·3 mmol/mol [3·0]), and FPG 5·9 mmol/L (0·6). There was a significantly greater reduction in bodyweight with semaglutide 2·4 mg than with placebo at week 52 (-13·9% [SD 0·7] vs -2·7% [0·6]; estimated treatment difference -11·2% [95% CI -13·0 to -9·4]; p<0·0001). Greater proportions of participants reverted to normoglycaemia at week 52 with semaglutide 2·4 mg than with placebo (103 [81%] of 127 vs nine [14%] of 64; odds ratio 19·8 [95% CI 8·7 to 45·2]; p<0·0001). Serious adverse events occurred in 12 (9%) participants receiving semaglutide 2·4 mg versus six (9%) receiving placebo. Adverse events leading to treatment discontinuation occurred in eight (6%) participants in the semaglutide 2·4 mg group versus one (1%) participant in the placebo group. No new safety signals were reported. Semaglutide 2·4 mg provided superior reduction in bodyweight and reversion to normoglycaemia versus placebo in participants with obesity and prediabetes. The safety and tolerability profile was consistent with previous studies and with the GLP-1 receptor agonist class. These findings support the potential use of semaglutide 2·4 mg as a treatment option for individuals with obesity and prediabetes to achieve reversion to normoglycaemia. Novo Nordisk.

Semaglutide in obesity-related heart failure with preserved ejection fraction and type 2 diabetes across baseline HbA(1c) levels (STEP-HFpEF DM): a prespecified analysis of heart failure and metabolic outcomes from a randomised, placebo-controlled trial.

About half of patients with heart failure with mildly reduced or preserved ejection fraction (HFpEF) have type 2 diabetes. In the STEP-HFpEF DM trial of adults with obesity-related HFpEF and type 2 diabetes, subcutaneous once weekly semaglutide 2·4 mg conferred improvements in heart failure-related symptoms and physical limitations, bodyweight, and other heart failure outcomes. We aimed to determine whether these effects of semaglutide differ according to baseline HbA1c. STEP-HFpEF DM, a double-blind, randomised, placebo-controlled trial conducted at 108 clinical research sites across 16 countries in Asia, Europe, and North and South America, included individuals aged 18 years or older with documented HFpEF (left ventricular ejection fraction ≥45%), type 2 diabetes, and obesity (BMI ≥30 kg/m2). Participants were randomly assigned (1:1), with a block size of four within each stratum using an interactive web response system, stratified by baseline BMI (<35 kg/m2vs ≥35 kg/m2), to receive either semaglutide 2·4 mg or placebo subcutaneously. The effects of semaglutide versus placebo on the efficacy endpoints were evaluated by HbA1c categories at baseline: low (<6·5%; <48 mmol/mol), medium (6·5% to <7·5%; 48 mmol/mol to <58 mmol/mol), and high (≥7·5%; ≥58 mmol/mol). The dual primary endpoints were change in the Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ-CSS) and bodyweight percentage from baseline to 52 weeks and were assessed in all randomly assigned participants by intention to treat. Hypoglycaemia events were also analysed to assess safety in all randomly assigned participants who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, NCT04916470. Between June 27, 2021 and Sept 2, 2022, 616 participants were enrolled and randomly assigned (mean age 68·4 years [SD 8·9]; 273 [44%] were female, 343 [56%] were male, and 519 [84%] were White). The low baseline HbA1c group included 227 participants (112 assigned to semaglutide and 115 to placebo), the medium baseline HbA1c group included 226 participants (124 assigned to semaglutide and 102 to placebo), and the high baseline HbA1c group included 163 participants (74 assigned to semaglutide and 89 to placebo). The median duration of follow-up in the overall trial was 401 days (IQR 400-405). The change in KCCQ-CSS from baseline to 52 weeks was 12·4 points (95% CI 8·8 to 16·0) with semaglutide versus 5·7 points (2·1 to 9·2) with placebo (mean difference 6·7 points [1·6 to 11·8]) in the low baseline HbA1c group, 14·5 points (11·0 to 17·9) versus 8·5 points (4·8 to 12·2; 6·0 points [0·9 to 11·1]) in the medium baseline HbA1c group, and 14·5 points (10·0 to 19·0) versus 4·8 points (0·7 to 8·9; 9·6 points [3·5 to 15·7]) in the high baseline HbA1c group (pinteraction=0·64; ptrend=0·46). The change in bodyweight percentage from baseline to 52 weeks was -10·8 (95% CI -12·1 to -9·5) with semaglutide versus -3·3% (-4·6 to -2·0) with placebo (mean difference -7·5% [-9·4 to -5·6]) in the low baseline HbA1c group, -9·6% (-10·8 to -8·3) versus -3·3% (-4·7 to -1·9; -6·3 [-8·2 to -4·4]) in the medium baseline HbA1c group, and -8·6% (-10·2 to -7·0) versus -3·6% (-5·2 to -2·1; -5·0 [-7·2 to -2·7]) in the high baseline HbA1c group (pinteraction=0·22; ptrend=0·083). Hypoglycaemia events occurred in 30 (10%) of 310 participants (70 events; 22·9 events per 100 person-years) in the semaglutide group compared with 21 (7%) of 306 participants in the placebo group (90 events; 29·5 events per 100 person-years). Semaglutide 2·4 mg improved heart failure-related symptoms and physical limitations, and reduced bodyweight in patients with obesity-related HFpEF and type 2 diabetes, all independently of baseline HbA1c, and resulted in lower rates of hypoglycaemia than placebo, despite a well controlled baseline HbA1c and broad use of concomitant glucose-lowering medications.
