Introduction Efpeglenatide is a long-acting glucagon-like peptide-1 receptor agonist being developed to improve glycemic control in type 2 diabetes (T2D). In the BALANCE 205 study (NCT02075281), efpeglenatide significantly reduced body weight versus placebo in patients with obesity, or overweight with comorbidities, and without T2D. These subanalyses explore the efficacy and safety of efpeglenatide in subgroups of patients with pre-diabetes and stratified by body mass index (BMI) or age from the BALANCE study.
Research design and methods The 20-week BALANCE study randomized patients with BMI ≥30 kg/m2 or ≥27 kg/m2 with comorbidities, and without diabetes, to efpeglenatide 4 mg or 6 mg once weekly, 6 mg or 8 mg once every 2 weeks, or placebo. For these subanalyses, patients were stratified by pre-diabetes status (glycated hemoglobin (HbA1c) 5.7%−6.4% (39–46 mmol/mol) or fasting plasma glucose (FPG) 100–125 mg/dL) and by BMI or age < or ≥ median values (34.9 kg/m2 and 44 years, respectively) at baseline.
Results In patients with pre-diabetes at baseline, all efpeglenatide doses led to greater proportions of patients reverting to normoglycemia (40.6%–64.3%) versus placebo (10.0%), and greater reductions in HbA1c (0.30%–0.38%), FPG (7.7–14.1 mg/dL), and weight (5.6–7.3 kg) versus placebo (nominal p<0.05 for all). In patients with BMI or age < or ≥ median, greater reductions in weight were observed with all efpeglenatide doses versus placebo (nominal p<0.01 for all). The most common adverse events in patients receiving efpeglenatide across patient subgroups were gastrointestinal adverse events.
Conclusions These results are consistent with the overall BALANCE population and suggest beneficial effects of efpeglenatide on glycemic control and body weight regardless of pre-diabetes status, age, or BMI at baseline. The effects of efpeglenatide on glycemic control in patients with pre-diabetes suggest it might help reduce the likelihood of at-risk patients developing diabetes.

Significance of this study
What is already known about this subject?
In the BALANCE 205 study, efpeglenatide, a long-acting glucagon-like peptide-1 receptor agonist in development to improve glycemic control in type 2 diabetes (T2D), significantly reduced body weight versus placebo in patients with obesity or overweight with comorbidities and without T2D.
What are the new findings?
In this subanalysis of the BALANCE 205 study, in patients with pre-diabetes at baseline, efpeglenatide led to greater proportions of patients reverting to normoglycemia versus placebo.
Greater reductions were also seen in glycated hemoglobin (HbA1c), fasting plasma glucose, and weight with efpeglenatide versus placebo.
In patients with body mass index (BMI) and age < or ≥ the median, greater reductions in weight were observed with efpeglenatide versus placebo.
How might these results change the focus of research or clinical practice?
Results from these subgroup analyses suggest beneficial effects of efpeglenatide on glycemic control and body weight regardless of pre-diabetes status, age, or BMI at baseline.
The effects of efpeglenatide on glycemic control in patients with pre-diabetes suggest it might help reduce the likelihood of at-risk patients developing diabetes.
Overall, these results suggest a potential role of efpeglenatide in the management of pre-diabetes and obesity.
Worldwide, the rates of overweight and obesity are at epidemic levels and continue to rise.1–3 Excess weight is associated with an increased risk of cardiometabolic syndrome and negative health consequences including hypertension, cardiovascular disease, type 2 diabetes (T2D), cancer, and premature mortality.1 Inflammation associated with increasing age, also termed ‘inflammageing’, is characterized by chronically elevated levels of proinflammatory cytokines, such as interleukin 6 and tumor necrosis factor-α, and is thought to be one of the factors that underpin the increased risk of all of these disorders as well as others.4 5 Age-related risk factors for T2D also include decreased beta-cell function and increased insulin resistance.5–7
Pre-diabetes, often associated with obesity, is defined in the 2021 American Diabetes Association Standards of Care as the presence of impaired fasting glucose and/or impaired glucose tolerance and/or glycated hemoglobin (HbA1c) 5.7%–6.4% (39–47 mmol/mol).8 Similar to obesity, meeting these criteria for impaired glucose tolerance is also an indicator of increased risk of diabetes and cardiovascular disease.8 9
Helping patients achieve a healthier weight is a well-established goal of medical treatment. However, there are few pharmacologic treatments available for weight reduction and the majority of these are administered daily (once to three times per day),10 with one recently approved once-weekly agent.11 In studies of osteoporosis and other chronic disease states, less-frequent dosing regimens have been associated with better adherence.12–14 Improved adherence, in turn, is likely to improve the efficacy of pharmacotherapy and long-term health outcomes, including treatments for obesity. In addition to positive effects on glycemic control, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have demonstrated efficacy in reducing the risk factors for cardiovascular disease, such as body weight, blood pressure, and cholesterol, in patients who are overweight or obese, with or without T2D.15
Efpeglenatide is a long-acting GLP-1 RA currently being developed to improve glycemic control in patients with T2D by subcutaneous once-weekly (QW) administration. It comprises a single amino acid-modified exendin conjugated to a fragment crystallizable region of human immunoglobulin 4 using long-acting peptide/protein technology.16–18 This type of conjugation extends the duration of action of efpeglenatide,19 while the flexible mini-polyethylene glycol linker minimizes the loss of intrinsic activity.16 In vitro, this has been shown to result in faster dissociation of efpeglenatide from the GLP-1 receptor, leading to reduced receptor internalization and desensitization, more cell surface receptor availability, and greater intracellular signaling compared with other GLP-1 RAs following chronic exposure.16 Efpeglenatide once weekly or once monthly has been shown to significantly improve glycemic control, reduce body weight, and reduce the risk of cardiovascular events in patients with T2D.20–22 The BALANCE 205 study (NCT02075281) examined the efficacy of efpeglenatide in patients with obesity or who were overweight with comorbidities and without T2D.23 All doses of efpeglenatide examined (QW or once every 2 weeks (Q2W)) significantly reduced body weight from baseline to week 21 versus placebo (p<0.0001; primary endpoint).23 The objective of these exploratory subanalyses was to explore the efficacy and safety of efpeglenatide in subgroups of patients from the BALANCE 205 study, stratified by pre-diabetes status, body mass index (BMI), and age at baseline.
The BALANCE study (NCT02075281) was a 20-week, randomized, placebo-controlled, double-blind, parallel-group trial (online supplemental figure S1); full study design has been published previously.23 All patients provided written informed consent. Details of the ethics review boards are provided in online supplemental table S1. Patients were required to have a BMI ≥30 kg/m2 or a BMI ≥27 kg/m2 with comorbidities and fasting plasma glucose (FPG) <126 mg/dL. Key exclusion criteria included BMI >42 kg/m2, drug-induced (iatrogenic) obesity, known diabetes, or HbA1c >6.5% (48 mmol/mol).
Eligible patients were randomized (1:1:1:1:1) to efpeglenatide 4 mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W, or placebo. Patients were instructed to reduce calorie intake by approximately 500 kcal each day and encouraged to increase physical activity. The primary efficacy endpoint was change from baseline (day 1 or last value observed prior to randomization if this was not available) in body weight to week 21 (ie, after 20 weeks of treatment).23
The first exploratory subgroup analysis of BALANCE investigated the efficacy and safety of efpeglenatide in patients with pre-diabetes (defined as HbA1c between 5.7% and 6.4% (which directly converts to 39–46 mmol/mol) or FPG 100–125 mg/dL) at baseline. The endpoints examined included the proportion of patients reverting to normoglycemia (defined as HbA1c <5.7% and FPG <100 mg/dL) at the end of the study, as well as change from baseline in HbA1c, FPG, body weight, waist circumference, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides. Both safety and efficacy endpoints were analyzed in patients with pre-diabetes from the full analysis set, defined as patients who received the study drug and who had at least one assessment recorded after dosing. All patients in the BALANCE study who received the study drug also had at least one assessment recorded, such that the safety set coincided with the full analysis set.
The second exploratory subgroup analysis included all of the patients in the full analysis set of the BALANCE study. Changes from baseline to week 21 versus placebo in body weight and waist circumference were assessed in patients stratified by BMI and age, either < or ≥ the median at baseline (median values: 34.9 kg/m2 and 44 years, respectively).
Gastrointestinal (GI) treatment-emergent adverse events (TEAEs) were described across patient subgroups. The following safety endpoints, which were assessed in the primary analysis,23 were also investigated in the pre-diabetes subgroup analysis: incidence of any TEAE, severe TEAE, and symptomatic hypoglycemia (as reported by patients in study diaries, with an alert value of FPG ≤70 mg/dL), including severe cases (defined as hypoglycemia requiring assistance from another person to administer carbohydrates or glucagon actively, or take other corrective actions).
In these exploratory subanalyses, no adjustments were made for multiplicity. All analyses were considered post-hoc and exploratory. Statistical Analysis System (SAS V.9.3) Proc Means was used to calculate the descriptive statistics and SAS Proc Mixed (V.9.3) was used to calculate the least squares (LS) mean and 95.1% CI. All p values are descriptive and further studies should be conducted to confirm these results.
Patient disposition, demographics, and baseline characteristics for the overall BALANCE study population have been published previously.23 In the overall population (n=295 randomized and received treatment), demographic and baseline characteristics were similar across the treatment groups.
A total of 140 patients met the criteria for pre-diabetes at baseline (HbA1c 5.7%−6.4% or FPG 100–125 mg/dL). Demographic and baseline characteristics were similar across the treatment groups (table 1). The median BMI in the overall study population was 34.9 kg/m2; 146 patients had a BMI < the median and 149 patients had a BMI ≥ the median. The median age was 44 years; 143 patients were < median age and 152 were ≥ median age. The numbers of patients below and above the median BMI and age were comparable between the treatment groups (table 1).
In the population with pre-diabetes, three patients discontinued treatment in the efpeglenatide 4 mg QW group, eight in the efpeglenatide 6 mg QW group, ten in the efpeglenatide 6 mg Q2W group, seven in the efpeglenatide 8 mg Q2W group, and five in the placebo group. The main reason for treatment discontinuation was an adverse event (AE): one in the efpeglenatide 4 mg QW group, five in the efpeglenatide 6 mg QW group, four in the efpeglenatide 6 mg Q2W group, five in the efpeglenatide 8 mg Q2W group, and two in the placebo group.
Pre-diabetes subgroup analysis
Among patients meeting the criteria for pre-diabetes at baseline, the proportion of patients reverting to normoglycemia by study end appeared numerically higher with all doses of efpeglenatide, both QW and Q2W, compared with placebo (64.3%, 46.2%, 40.6%, 41.7%, and 10.0% for 4 mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W, and placebo, respectively; figure 1), although statistical analysis was not performed. In addition, all efpeglenatide doses examined led to greater reductions from baseline to week 21 compared with placebo in HbA1c (LS mean difference for the overall efpeglenatide group (n=110) vs placebo (n=30): –0.35% (95.1% CI –0.43 to –0.26), nominal p<0.0001; figure 2A) and FPG (LS mean difference for the overall efpeglenatide group (n=110) vs placebo (n=30): –11.19 mg/dL (–0.62 mmol/L) (95.1% CI –16.57 to –5.81), nominal p<0.0001; figure 2B). LS mean treatment differences in HbA1c for the individual efpeglenatide groups versus placebo ranged from –0.30% (–3.29 mmol/mol) for the 4 mg QW group to –0.38% (–4.21 mmol/mol) for the 6 mg Q2W group (all nominal p<0.0001 vs placebo). For FPG, individual LS mean differences between efpeglenatide and placebo ranged from –7.72 mg/dL (–0.43 mmol/L, nominal p=0.0221) for the 4 mg QW group to –14.06 mg/dL (–0.78 mmol/L, nominal p=0.0001) in the 6 mg Q2W group.
Greater reductions in body weight (nominal p<0.0001; figure 2C) were also observed with efpeglenatide compared with placebo, and these reductions were comparable in patients with or without pre-diabetes (figure 2C). In the efpeglenatide 4 mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W, and placebo groups, the absolute LS mean reductions in weight in those with pre-diabetes were –5.7 kg, –7.3 kg, –6.6 kg, –7.4 kg, and –0.1 kg, respectively. The LS mean differences in weight loss between the efpeglenatide groups and the placebo group ranged from –5.61 kg in the 4 mg QW group to –7.32 kg in the 8 mg Q2W dose group (nominal p<0.0001 for all groups). Efpeglenatide led to greater reductions in waist circumference compared with placebo (LS mean difference vs placebo of –3.1 cm, –4.7 cm, –5.2 cm, and –7.7 cm for 4 mg QW, 6 mg QW, 6 mg Q2W, and 8 mg Q2W, respectively; nominal p<0.05 for all except 4 mg QW) (online supplemental figure S2).
Compared with placebo, all doses of efpeglenatide led to greater reductions in total cholesterol from baseline to week 21 (LS mean difference vs placebo of –15.4 mg/dL (nominal p=0.02), –19.7 mg/dL (nominal p=0.04), –14.9 mg/dL (nominal p=0.02), and –14.0 mg/dL (nominal p=0.04) for 4 mg QW, 6 mg QW, 6 mg Q2W, and 8 mg Q2W, respectively) (online supplemental figure S3). With the exception of the effects of the efpeglenatide 6 mg QW dose on LDL (LS mean change vs placebo of –20.0 mg/dL, nominal p=0.002), reductions in LDL, HDL, and triglycerides with efpeglenatide did not achieve nominal statistical significance compared with placebo.
BMI and age subgroup analysis
Across all BMI and age subgroups (either < or ≥ median), all doses of efpeglenatide were associated with greater reductions in body weight (nominal p<0.01; figure 3A) from baseline to week 21 compared with placebo. In patients with age < median, mean weight changes of –7.8 kg, –7.6 kg, –6.6 kg, –6.8 kg, and 0.5 kg were observed in the 4 mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W, and placebo groups, respectively. The LS mean difference in body weight between the efpeglenatide groups and placebo in patients with age < median was –8.39 kg, –7.55 kg, –7.27 kg, and –7.53 kg (nominal p<0.0001 for all doses) in the 4 mg QW (n=28), 6 mg QW (n=31), 6 mg Q2W (n=28), and 8 mg Q2W (n=28) dose groups, respectively. In patients with age ≥ median, mean decreases in weight of –5.8 kg, –8.2 kg, –6.8 kg, –7.4 kg, and –0.8 kg were observed in the 4 mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W, and placebo groups, respectively. The LS mean difference in body weight between the efpeglenatide groups and placebo in patients with age ≥ median was –5.21 kg, –7.18 kg, –5.56 kg, and –6.44 kg (nominal p<0.0001 vs placebo for all doses) in the 4 mg QW (n=31), 6 mg QW (n=28), 6 mg Q2W (n=31), and 8 mg Q2W (n=30) dose groups, respectively. Greater reductions in waist circumference were also observed with efpeglenatide compared with placebo across subgroups (figure 3B; nominal p<0.05 for all except the lower QW and Q2W doses in subgroups with BMI ≥ median (4 mg QW and 6 mg Q2W) and age ≥ median (4 mg QW)).
Pre-diabetes subgroup analysis
In patients with pre-diabetes at baseline, TEAEs were reported in 85.7%, 88.5%, 96.9%, 87.5%, and 80.0% of the efpeglenatide 4 mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W, and placebo groups, respectively (online supplemental table S2). As expected with treatment with a GLP-1 RA, GI disorders were more common in the efpeglenatide-treated groups compared with placebo; the rates of GI TEAEs were 64.3%, 76.9%, 71.9%, 70.8%, and 40.0% in the efpeglenatide 4 mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W, and placebo groups, respectively. While the incidence of nausea and vomiting was greater with efpeglenatide versus placebo, the incidence of diarrhea was generally greater with placebo versus efpeglenatide groups in patients with pre-diabetes at baseline (online supplemental table S2). The rates of serious TEAEs were generally low and no serious TEAEs were reported in either the placebo or efpeglenatide 6 mg Q2W group. One case of symptomatic hypoglycemia was reported, in the efpeglenatide 6 mg QW group; the event was not severe.
BMI and age subgroup analysis
Similar to patients with pre-diabetes at baseline and consistent with the overall BALANCE population, the most common TEAEs in patient subgroups stratified by BMI or age were GI TEAEs such as nausea (incidence range: efpeglenatide, 38.7%–73.3%; placebo, 14.3%–21.9%), vomiting (efpeglenatide, 12.9%–40.0%; placebo, 3.6%–9.4%), and diarrhea (efpeglenatide, 5.6%–43.5%; placebo, 17.2%–22.6%) (online supplemental table S3). No events of pancreatitis were observed. Increases in amylase and lipase were uncommon overall (online supplemental table S3).
Here we have shown data from two subanalyses of the BALANCE study stratified by pre-diabetes status, BMI, and age at baseline. These are commonly observed clinical variables in patients with diabetes and these subanalyses could help to identify response to efpeglenatide in particular patient subgroups.
In patients who had pre-diabetes at baseline, all doses of efpeglenatide led to numerically greater proportions of patients reverting to normoglycemia at the end of the study versus placebo. We observed some potential differences between efpeglenatide groups in terms of achievement of normoglycemia, although statistical testing was not performed. The mean baseline HbA1c and FPG of the group with pre-diabetes were approximately 5.7% (39 mmol/mol) and 102 mg/dL (5.7 mmol/L), respectively. This is close to the lower limit of pre-diabetes as defined by the American Diabetes Association (HbA1c 5.7%–6.4% (39–47 mmol/mol) and FPG of 100–125 mg/dL (5.6–6.9 mmol/L)),8 suggesting that some patients in the pre-diabetes group were very close to being normoglycemic. This may explain, at least in part, the high proportions of patients returning to normoglycemia following efpeglenatide treatment and why the highest rate of reversion was observed with the 4 mg QW dose, despite larger reductions in HbA1c and FPG in the other efpeglenatide dose groups.
Treatment with efpeglenatide was also associated with greater improvements from baseline in HbA1c, FPG, body weight, waist circumference, and total cholesterol compared with placebo. Due to the exploratory nature of the study design, statistical testing was not performed to compare efpeglenatide groups.
In subgroups of patients from the overall BALANCE population, stratified by baseline BMI or age, all doses of efpeglenatide were associated with greater reductions in body weight versus placebo across all subgroups of patients stratified by age and BMI. For waist circumference, the highest QW and Q2W doses of efpeglenatide were associated with reductions versus placebo. Therefore, these exploratory data suggest that efpeglenatide may be beneficial in people with pre-diabetes and that this is an area that requires further study. The results of these subgroup analyses were consistent with those of the overall BALANCE study, with all doses of efpeglenatide associated with greater reductions in body weight compared with placebo across all patient subgroups examined.23 Similarly, the benefits of efpeglenatide on glycemic control and cholesterol levels seen in BALANCE23 were also seen in patients with pre-diabetes, who experienced greater reductions in HbA1c, FPG, and total cholesterol, compared with patients receiving placebo. In the overall BALANCE study population, all doses of efpeglenatide led to greater reductions in waist circumference compared with placebo;23 this treatment effect was seen with most doses of efpeglenatide across the subgroups investigated, with more consistent benefits observed at the higher doses examined. In line with the overall BALANCE population and the GLP-1 RA class, the most common AEs in these subgroup analyses were GI AEs such as nausea, vomiting, and diarrhea. The goal of treatment for pre-diabetes is preventing progression to diabetes, and lifestyle modification is considered as the first-line therapy.24 25 Intensive behavioral lifestyle intervention programs have been shown to reduce the risk of progression to diabetes.25 Several pharmacologic agents, primarily metformin, have also been shown to reduce the risk of disease progression, although further study is needed. In practice, however, pre-diabetes often goes unaddressed in primary care settings.26
Currently, there are two GLP-1 RAs approved for body weight management in patients with obesity and without diabetes: liraglutide, administered as a once-daily injection;27 and semaglutide, administered QW.11 In a trial in patients with obesity and without T2D, 20-week treatment with liraglutide 1.8–3.0 mg once daily led to an 84%–96% decrease in the prevalence of pre-diabetes (defined as FPG 5.6–6.9 mmol/L (100–125 mg/dL) or glucose tolerance 7.8–11.0 mmol/L (140–199 mg/dL) measured during an oral glucose tolerance test).28 Liraglutide was also shown to reduce the incidence of progression to T2D in a study of adults with pre-diabetes and a BMI ≥30 kg/m² (or ≥27 kg/m² with comorbidities). Of patients treated with liraglutide, 2% were diagnosed with diabetes after 3 years compared with 6% of the placebo group, and the time from randomization to diagnosis was 2.7 times longer with liraglutide than with placebo (p<0.0001).29 The recent Semaglutide Treatment Effect in People with Obesity (STEP) phase III clinical trial program explored the efficacy and safety of once-weekly semaglutide in overweight adults without diabetes with a BMI of ≥30 kg/m2 or ≥27 kg/m2 (STEP 1, STEP 3, and STEP 4)30–32 or in adults with T2D with BMI ≥27 kg/m2 (STEP 2).33 All trials showed that semaglutide was associated with significantly greater body weight reductions and a greater proportion of patients achieved weight loss of 5% or greater compared with placebo.30–33 The STEP 1 study also showed that, of patients with pre-diabetes, 84.1% of those in the once-weekly semaglutide group reverted to normoglycemia after 68 weeks of treatment, compared with 47.8% in the placebo group.30
In the BALANCE study, the rates of GI AEs (ie, nausea, vomiting, diarrhea, dyspepsia, and constipation) with efpeglenatide in the pre-diabetes population were consistent with those in the overall study population23; these rates were similar to those observed with liraglutide and semaglutide in phase II studies in patients with obesity.28 34 In the present analysis, the rates of GI AEs were generally slightly higher in patients with BMI below the median compared with BMI at the median or greater. Although one study found lower weight to be associated with GI AEs in univariate analyses among patients taking liraglutide, another found similar rates of GI AEs in patients with BMI <35 kg/m2 compared with BMI ≥35 kg/m2.35 36 Statistical comparisons of GI AEs between the different efpeglenatide dose groups were not performed in either subgroup analysis.
The limitations of the BALANCE 205 study have been described previously.23 This was a phase II study with associated limitations in terms of sample size and study duration. The small sample size could have limited the statistical power needed to detect significance for some endpoints; this issue of small sample size was exacerbated further by dividing the sample into even smaller subgroups. Small group sizes and large variability may have contributed to the finding that reductions in total cholesterol were significantly greater with all doses of efpeglenatide versus placebo, but the differences in change in LDL, HDL, and triglycerides were not. Finally, adjustments for multiple comparisons were not used for these exploratory analyses. As such, the p values reported are nominal and these results are considered hypothesis-generating. Further research is needed to confirm these outcomes.
Overall, the findings from these subgroup analyses are consistent with those of the BALANCE study and suggest that efpeglenatide leads to improvements in weight reduction in key subgroups of patients with obesity or who are overweight (with comorbidity) and without diabetes. They suggest that treatment effects are independent of baseline characteristics such as patient age or BMI. In addition, the benefits of efpeglenatide on glycemic control in patients with pre-diabetes suggest that it may help patients at risk of developing diabetes to achieve normoglycemia. These promising results would need to be replicated in larger, long-term studies in patients with pre-diabetes. However, while these findings are hypothesis-generating, they support further investigation and development of efpeglenatide in patients with obesity and who are overweight (with comorbidity) and without diabetes, and suggest a potential role of efpeglenatide in the management of pre-diabetes and obesity.
