Treatment effect heterogeneity following type 2 diabetes treatment with GLP1-receptor agonists and SGLT2-inhibitors: a systematic review. COMMUNICATIONS MEDICINE 2023; 3:131.

Abstract
BACKGROUND A precision medicine approach in type 2 diabetes requires the identification of clinical and biological features that are reproducibly associated with differences in clinical outcomes with specific anti-hyperglycaemic therapies. Robust evidence of such treatment effect heterogeneity could support more individualized clinical decisions on optimal type 2 diabetes therapy. METHODS We performed a pre-registered systematic review of meta-analysis studies, randomized control trials, and observational studies evaluating clinical and biological features associated with heterogenous treatment effects for SGLT2-inhibitor and GLP1-receptor agonist therapies, considering glycaemic, cardiovascular, and renal outcomes. After screening 5,686 studies, we included 101 studies of SGLT2-inhibitors and 75 studies of GLP1-receptor agonists in the final systematic review. RESULTS Here we show that the majority of included papers have methodological limitations precluding robust assessment of treatment effect heterogeneity. For SGLT2-inhibitors, multiple observational studies suggest lower renal function as a predictor of lesser glycaemic response, while markers of reduced insulin secretion predict lesser glycaemic response with GLP1-receptor agonists. For both therapies, multiple post-hoc analyses of randomized control trials (including trial meta-analysis) identify minimal clinically relevant treatment effect heterogeneity for cardiovascular and renal outcomes. CONCLUSIONS Current evidence on treatment effect heterogeneity for SGLT2-inhibitor and GLP1-receptor agonist therapies is limited, likely reflecting the methodological limitations of published studies. Robust and appropriately powered studies are required to understand type 2 diabetes treatment effect heterogeneity and evaluate the potential for precision medicine to inform future clinical care.

Plain language summary This review identifies research that helps understand which clinical and biological factors that are associated with different outcomes for specific type 2 diabetes treatments. This information could help clinical providers and patients make better informed personalized decisions about type 2 diabetes treatments. We focused on two common type 2 diabetes treatments: SGLT2-inhibitors and GLP1-receptor agonists, and three outcomes: blood glucose control, heart disease, and kidney disease. We identified some potential factors that are likely to lessen blood glucose control including lower kidney function for SGLT2-inhibitors and lower insulin secretion for GLP1-receptor agonists. We did not identify clear factors that alter heart and renal disease outcomes for either treatment. Most of the studies had limitations, meaning more research is needed to fully understand the factors that influence treatment outcomes in type 2 diabetes.

Abstract
INTRODUCTION This analysis aims to investigate the efficacy and safety of once-daily lixisenatide add-on treatment to basal insulin in Asian individuals with type 2 diabetes, by baseline body mass index (BMI). RESEARCH DESIGN AND METHODS Data from all Asian participants in the placebo-controlled GetGoal-Duo 1, GetGoal-L, and GetGoal-L-C Studies were pooled and categorized according to the following BMI subgroups:<25 kg/m2, 25-<30 kg/m2 and ≥30 kg/m2. Efficacy and safety of lixisenatide versus placebo were evaluated among BMI subgroups. Multivariable regression analyses were also conducted to explore the potential influence of BMI on efficacy outcomes after adjusting for baseline characteristics. RESULTS 555 participants were included (mean age 53.9 years, 52.4% men). No significant differences in treatment effect between the BMI subgroups were observed for the changes from baseline to 24 weeks in glycated hemoglobin (HbA1c), fasting plasma glucose, postprandial glucose (PPG), PPG excursion, body weight, BMI, and basal insulin dose with lixisenatide, as well as the change in basal insulin dose at study endpoint and the proportion of participants achieving an HbA1c <7% at 24 weeks (all p values for interaction >0.15). In the multivariable regression analysis, participants in the lowest BMI group had a smaller reduction in body weight over the 24-week treatment period relative to the highest BMI group (p=0.023). CONCLUSIONS This post hoc analysis indicates that lixisenatide improved glycemic control regardless of baseline BMI and was well tolerated in Asian individuals unable to achieve their HbA1c target on basal insulin±oral antidiabetic drugs.

Intensification of Basal Insulin Therapy with Lixisenatide in Patients with Type 2 Diabetes in a Real-World Setting: The BASAL-LIXI Study. Curr Ther Res Clin Exp 2018; 89:37-42. [PMID: 30455779 PMCID: PMC6218842 DOI: 10.1016/j.curtheres.2018.09.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Revised: 09/27/2018] [Accepted: 09/28/2018] [Indexed: 01/02/2023] Open
Abstract
Adding lixisenatide to basal insulin was effective for uncontrolled type 2 diabetes. Glycemic control improved and body weight lowered during 24 weeks of treatment. These benefits were achieved with a low risk of hypoglycemia in clinical practice. These findings in the clinical practice setting support those of clinical trials.
Background Basal insulin reduces fasting blood glucose levels, but postprandial blood glucose levels may remain higher. Traditional strategies with rapid insulin intensification can cause hypoglycemic episodes and weight gain. Glucagon-like peptide-1 receptor agonists, such as the short-acting lixisenatide, are able to control postprandial excursions, without weight gain, and with a low risk of hypoglycemic events. Objective Due to the limited data on the combination of lixisenatide with basal insulin (with or without oral antidiabetes drugs) in clinical practice, this study evaluated changes in parameters associated with glycemic control and anthropometric data after 24 weeks of this therapy intensification. Methods This was a multicenter, retrospective observational study of 129 patients with type 2 diabetes that was uncontrolled by basal insulin. Their treatment was intensified by the addition of lixisenatide at least 24 weeks before being included in the study. Data were retrospectively collected to determine changes in glycated hemoglobin (HbA1c) levels, blood glucose levels, weight, and body mass index. Adverse reactions and hypoglycemic events were also recorded. Results After 24 weeks of therapy intensification with lixisenatide, a significant reduction in HbA1c levels was observed (–1.1%; P < 0.001). An HbA1c <7% was achieved in 30.2% of patients, and 17.1% reached an HbA1c <6.5%. There was a reduction in fasting blood glucose (31.8 [60.3] mg/dL; P < 0.001) and postprandial blood glucose (55.0 [49] mg/dL; P < 0.001) levels, as well as body weight (4.0 [5.4] kg; P < 0.001) and body mass index (1.5 [1.9]; P < 0.001). The most commonly observed adverse reactions were nausea (n = 9), in line with previous studies. Hypoglycemia events were rare; only reported in 2 patients. Conclusions Intensification strategy based on lixisenatide added to basal insulin (with or without oral antidiabetes drugs) can be an effective treatment option in patients with uncontrolled type 2 diabetes. In this small, selected population, glycemic control was significantly improved in terms of HbA1, fasting blood glucose levels, and postprandial glucose levels, with a reduction of body weight and low risk of hypoglycemic events.

Abstract
Lixisenatide, a short-acting glucagon-like peptide-1 receptor agonist (GLP-1 RA), has been available in Europe since 2013 and was recently approved in the United States for the treatment of type 2 diabetes (T2D) as an adjunct to diet and exercise. The objective of this systematic review is to describe the pharmacology, pharmacokinetics, safety, and efficacy of lixisenatide in patients with T2D. We conducted a search of the EMBASE database, limited to human studies with abstracts available in English. Published conference abstracts, limited to the American Diabetes Association (ADA) and the European Association for the Study of Diabetes meetings in 2015, as well as abstracts presented at the ADA meeting in 2016, were also screened. The abstracts retrieved were assessed for relevance; review articles and meta-analyses focusing on GLP-1 RAs as a class were excluded. Lixisenatide induced mean reductions of 0.46-0.99% in glycated hemoglobin A1c (HbA1c ), 55.86-143.43 mg/dl in 2-hour postprandial glucose (PPG) levels, and 56.58-127.75 mg/dl in mealtime glucose level variations. Changes in fasting plasma glucose (FPG) levels and weight ranged from -21.98 to +5.41 mg/dl and from -2.96 to +0.3 kg, respectively, in patients with T2D enrolled in the GetGoal clinical program (a program of clinical trials that established the efficacy and safety profile of lixisenatide 20 μg once/day across patients with T2D with differing background therapies). Lixisenatide was well tolerated, demonstrating rates of symptomatic hypoglycemia of 0.8-42.9% and a very low rate of severe hypoglycemia (< 1.5%) as well as no increased risk of cardiovascular events. The most common adverse events were gastrointestinal in nature, mainly transient nausea and vomiting of mild-to-moderate severity. Lixisenatide effectively lowers HbA1c levels in patients with T2D through a mechanism of action complementary to that of agents that mainly target FPG, with the additional benefit of weight loss. Its once-daily administration schedule and effect on PPG levels make it an attractive option as add-on treatment to basal insulin therapy or oral antidiabetic agents.

Abstract
AIM/INTRODUCTION To assess the overall safety and efficacy of lixisenatide in combination with background oral antidiabetic drug treatment in Japanese patients with type 2 diabetes, as required by Japanese guidelines. MATERIALS AND METHODS A phase 3, multicenter, uncontrolled, open-label, four-arm, parallel-group study of Japanese outpatients with type 2 diabetes was carried out; patients received once-daily lixisenatide in combination with biguanide, thiazolidinedione, alpha-glucosidase inhibitors or glinide (NCT01940965). The primary end-point was safety over 52 weeks; secondary end-points included absolute change from baseline in glycated hemoglobin A1c at weeks 24 and 52. RESULTS A total of 294 patients were enrolled (biguanide, thiazolidinedione, alpha-glucosidase groups: 73 patients each; glinide group: 75 patients). Overall, 90.4% of patients in the biguanide group, 83.6% in the thiazolidinedione group, 83.6% in the alpha-glucosidase group and 85.3% in the glinide group reported one or more treatment-emergent adverse event, the most common of which were nasopharingitis, nausea and constipation. Symptomatic hypoglycemia was reported in 5.5, 0, 1.4, and 10.7% of patients in the biguanide, thiazolidinedione, alpha-glucosidase and glinide groups, respectively. No severe hypoglycemia was observed. Hemoglobin A1c decreased from baseline at weeks 24 and 52, with mean changes ranging from -0.98 to -1.22%, and from -0.80 to -1.08%, respectively, across all groups. CONCLUSIONS Lixisenatide treatment administered daily over 52 weeks was well tolerated and effective in improving glycemic control in Japanese patients with type 2 diabetes uncontrolled with existing oral antidiabetic drug therapies. The use of lixisenatide in combination with oral antidiabetic drugs is a valuable treatment option for Japanese patients with type 2 diabetes after failure of oral antidiabetic treatment alone.

Abstract
This post hoc analysis assessed the evidence behind common reimbursement practices by evaluating the relationship of body mass index (BMI) ranges (<30, 30-35 and >35 kg/m(2) ) with treatment effects of exenatide twice daily among patients with type 2 diabetes. Patients received exenatide twice daily added to insulin glargine in two 30-week studies (exenatide twice daily vs insulin lispro, n = 627; exenatide twice daily vs placebo, n = 259). No association of baseline BMI with changes in efficacy variables was observed. Glycated haemoglobin (HbA1c) reductions were significant (p < 0.0001) and similar across BMI range groups in the lispro-comparator study and greater for exenatide versus placebo in the placebo-controlled study. Significant weight loss occurred with exenatide across BMI range groups (p < 0.0001), while weight increased with both comparators. Achievement of HbA1c <7.0% (<53 mmol/mol) without weight gain was greater for exenatide versus comparators. Systolic blood pressure decreased across BMI range groups with exenatide in the lispro-comparator study (p < 0.0001); changes in lipids were not clinically meaningful. Minor hypoglycaemia was less frequent for exenatide versus insulin lispro. These findings suggest that BMI alone should not limit clinical decision-making or patient access to medication.
