The efficacy and safety of iGlarLixi versus IDegAsp in Chinese people with type 2 diabetes suboptimally controlled with oral antidiabetic drugs: The Soli-D randomized controlled trial.

AIM: To compare the efficacy and safety of a fixed-ratio combination of insulin glargine 100 U/mL plus lixisenatide (iGlarLixi) with premixed insulin, insulin degludec plus insulin aspart (IDegAsp), in Chinese people with type 2 diabetes (T2D) suboptimally controlled with oral antidiabetic drug(s) (OADs). METHODS: In Soli-D, a 24-week, multicentre, open-label, study, insulin-naïve adults were randomized 1:1 to once-daily injections of iGlarLixi (n = 291) or IDegAsp (n = 291), with continued metformin ± sodium-glucose co-transporter-2 inhibitors. The primary endpoint was non-inferiority in HbA1c change from baseline to week 24. Key secondary endpoints included superiority in HbA1c change and body weight (BW) change at week 24. Hypoglycaemia rates were also assessed. RESULTS: At week 24, iGlarLixi showed non-inferiority and superiority over IDegAsp in HbA1c reduction (least squares [LS] mean difference: -0.20 [95% confidence interval {CI}: -0.33, -0.07]; P < .001 for non-inferiority; [97.5% CI: -0.35, -0.05]; P = .003 for superiority). iGlarLixi decreased BW and IDegAsp increased BW from baseline to week 24, with a statistically significant LS mean difference of -1.49 kg in favour of iGlarLixi (97.5% CI: -2.32, -0.66; P < .001). Event rates (per person-year) for American Diabetes Association (ADA) Level 1, 2 or 3 hypoglycaemia were lower for iGlarLixi (1.90) versus IDegAsp (2.72) (relative risk: 0.71; 95% CI: 0.52, 0.98). No ADA Level 3 hypoglycaemia or unexpected safety findings were reported. CONCLUSIONS: In Chinese people with T2D suboptimally controlled with OADs, once-daily iGlarLixi provided better glycaemic control with BW benefit and lower hypoglycaemia event rates versus IDegAsp.

iGlarLixi provides a higher derived time-in-range versus insulin glargine 100 U/mL or lixisenatide in Asian Pacific people with type 2 diabetes: A post hoc analysis.

AIM: To evaluate the efficacy of iGlarLixi in the Asian Pacific (AP) population with type 2 diabetes (T2D) using derived time-in-ranges calculated from seven-point self-measured blood glucose. METHODS: Two phase III trials were analysed. LixiLan-O-AP was performed in insulin-naive T2D patients (n = 878) randomized to iGlarLixi, glargine 100 units/mL (iGlar) or lixisenatide (Lixi). LixiLan-L-CN was performed in insulin-treated T2D patients (n = 426) randomized to iGlarLixi or iGlar. Changes in derived time-in-ranges from baseline to end-of-treatment (EOT) and estimated treatment differences (ETDs) were analysed. The proportions of patients achieving 70% or higher derived time-in-range (dTIR), 5% or higher dTIR improvement, and the composite triple target (≥ 70% dTIR, < 4% derived time-below-the-range [dTBR] and < 25% derived time-above-the-range [dTAR]) were calculated. RESULTS: The changes from baseline to EOT in dTIR with iGlarLixi were greater versus iGlar (ETD1 : 11.45% [95% CI, 7.66% to 15.24%]) or Lixi (ETD2 : 20.54% [95% CI, 15.74% to 25.33%]) in LixiLan-O-AP, and versus iGlar (ETD: 16.59% [95% CI, 12.09% to 21.08%]) in LixiLan-L-CN. In LixiLan-O-AP, the proportions of patients achieving 70% or higher dTIR or 5% or higher dTIR improvement at EOT with iGlarLixi were 77.5% and 77.8%, respectively, higher than with iGlar (61.1% and 75.3%) or Lixi (47.0% and 53.0%). In LixiLan-L-CN, the proportions of patients achieving 70% or higher dTIR or 5% or higher dTIR improvement at EOT were 71.4% and 59.8% with iGlarLixi, greater than with iGlar (45.4% and 39.5%). More patients achieved the triple target with iGlarLixi compared with iGlar or Lixi. CONCLUSION: iGlarLixi achieved greater improvements in dTIR parameters versus iGlar or Lixi in insulin-naïve and insulin-experienced AP people with T2D.

Hypoglycaemia events with iGlarLixi versus premix biphasic insulin aspart 30 (BIAsp 30) in people with type 2 diabetes advancing from basal insulin: An analysis of the SoliMix trial.

AIMS: To explore details of the incidence and rates of daytime and nocturnal hypoglycaemia, levels of hypoglycaemia, and relationship to glycated haemoglobin (HbA1c), when comparing iGlarLixi versus premixed biphasic insulin aspart 30 (BIAsp 30) in the SoliMix randomized controlled trial. MATERIALS AND METHODS: This exploratory analysis of SoliMix used logistic regression and negative binomial regression analyses to assess between-treatment differences in the incidence and rates of hypoglycaemia by time of day. A negative binomial model was used to derive estimated annualized hypoglycaemia rates as a function of HbA1c. RESULTS: iGlarLixi was associated with lower incidence and rates of American Diabetes Association Level 2 (<54 mg/dL [<3.0 mmol/L]) hypoglycaemia during both night and day versus BIAsp 30. Incidence and rates of Level 1 (<70 to ≥54 mg/dL [<3.9 to ≥3.0 mmol/L]) hypoglycaemia were also mostly shown to be reduced with iGlarLixi versus BIAsp 30. Severe (Level 3) events were too few for analysis (n = 3). iGlarLixi was associated with lower modelled event rates of Level 2 and Level 1 hypoglycaemia over a wide range of HbA1c levels versus BIAsp 30. CONCLUSIONS: These results show that the lower HbA1c levels and weight benefit seen with iGlarLixi versus premixed BIAsp 30 in people with type 2 diabetes advancing their basal insulin therapy in the SoliMix trial are also accompanied by a lower risk of hypoglycaemia at any time of day and across a broad range of HbA1c levels.

Improved glycaemic control and weight benefit with iGlarLixi versus insulin glargine 100 U/mL in Chinese people with type 2 diabetes advancing their therapy from basal insulin plus oral antihyperglycaemic drugs: Results from the LixiLan-L-CN randomized controlled trial.

AIMS: To evaluate the efficacy and safety of iGlarLixi compared with iGlar in Chinese adults with type 2 diabetes advancing therapy from basal insulin ± oral antihyperglycaemic drugs. MATERIALS AND METHODS: LixiLan-L-CN (NCT03798080) was a 30-week randomized, active-controlled, open-label, parallel-group, multicentre study. Participants were randomized 1:1 to iGlarLixi or iGlar. The primary objective was to show the superiority of iGlarLixi over iGlar in glycated haemoglobin (HbA1c) change from baseline to Week 30. RESULTS: In total, 426 participants were randomized to iGlarLixi (n = 212) or iGlar (n = 214). Mean age was 58 years, 67% had a body mass index ≥24 kg/m2 , corresponding to overweight/obesity, and the mean diabetes duration was 12.3 years. From mean baseline HbA1c of 8.1% in both groups, greater decreases were seen with iGlarLixi versus iGlar [least squares mean difference: -0.7 (95% confidence interval: -0.9, -0.6)%; p < .0001] to final HbA1c of 6.7% and 7.4%, respectively. HbA1c <7.0% achievement was greater with iGlarLixi (63.3%) versus iGlar (29.9%; p < .0001). Mean body weight decreased with iGlarLixi and increased with iGlar [least squares mean difference: -0.9 (95% confidence interval: -1.4, -0.5) kg; p = .0001]. Hypoglycaemia incidence was similar between groups. Few gastrointestinal adverse events occurred (rated mild/moderate) with a slightly higher incidence with iGlarLixi than iGlar. CONCLUSIONS: iGlarLixi provided better glycaemic control and facilitated more participants to reach glycaemic targets alongside beneficial effects on body weight, no additional risk of hypoglycaemia, and few gastrointestinal AEs, supporting iGlarLixi use as an efficacious and well tolerated therapy option in Chinese people with long-standing T2D advancing therapy from basal insulin.

Efficacy of iGlarLixi in adults with type 2 diabetes inadequately controlled (glycated haemoglobin ≥8%, ≥64 mmol/mol) on two oral antidiabetes drugs: Post hoc analysis of the LixiLan-O randomized trial.

AIMS: To assess the efficacy and safety of iGlarLixi (the titratable fixed-ratio combination of insulin glargine 100 U/mL [iGlar] plus lixisenatide [Lixi]), in adults with type 2 diabetes (T2D) with glycated haemoglobin (HbA1c) levels ≥8% (≥64 mmol/mol). MATERIALS AND METHODS: The LixiLan-O study (NCT02058147) compared iGlarLixi with iGlar or Lixi in adults with T2D inadequately controlled on metformin ± a second oral antidiabetes drug (OAD). This exploratory analysis evaluated the LixiLan-O subgroup of participants with baseline HbA1c levels of ≥8% (≥64 mmol/mol) who were receiving metformin plus a second OAD at screening. RESULTS: The mean diabetes duration was 10.0 years, and the mean duration of second OAD use was 4.5 years. iGlarLixi demonstrated greater mean reductions from baseline in HbA1c and 2-hour postprandial glucose (PPG) compared with iGlar or Lixi (HbA1c -1.9% vs. -1.6% or -1.0% [-20 vs. -17 or -10 mmol/mol; 2-hour PPG -7.2 vs. -4.6 or -5.5 mmol/L). Greater proportions of participants achieved HbA1c <7% (<53 mmol/mol) with iGlarLixi versus iGlar or Lixi (67% vs. 51% or 18%), and the composite endpoints of HbA1c <7% (<53 mmol/mol) with no body weight gain (36% vs. 19% or 16%), and HbA1c <7% (<53 mmol/mol) with no body weight gain and no documented symptomatic hypoglycaemia (plasma glucose ≤3.9 mmol/L; 28% vs. 15% or 15%). The incidence rates of documented symptomatic hypoglycaemia were 29.0%, 27.9% and 12.1% for iGlarLixi, iGlar and Lixi, respectively. CONCLUSIONS: Adults with T2D and HbA1c ≥64 mmol/mol (≥8%) despite two OADs at screening achieved better glycaemic control with iGlarLixi versus iGlar or Lixi, without increased risk of hypoglycaemia versus iGlar.

Efficacy and safety benefits of iGlarLixi versus insulin glargine 100 U/mL or lixisenatide in Asian Pacific people with suboptimally controlled type 2 diabetes on oral agents: The LixiLan-O-AP randomized controlled trial.

AIMS: To compare the efficacy and safety of iGlarLixi with insulin glargine 100 units/mL (iGlar) and lixisenatide (Lixi), in Asian Pacific people with suboptimally controlled type 2 diabetes (T2D) on metformin with or without a second oral antihyperglycaemic drug (OAD). MATERIALS AND METHODS: LixiLan-O-AP (NCT03798054) was a 24-week multicentre study in adults (n = 878, mean age 56.0 years, mean body mass index 26.0 kg/m2 ) with glycated haemoglobin (HbA1c) levels ≥53 mmol/mol (7%) and ≤97 mmol/mol (11%) on OAD(s), randomized (2:2:1) to open-label once-daily iGlarLixi, iGlar or Lixi while on continued metformin ± sodium-glucose cotransporter-2 inhibitors. The primary efficacy endpoint was change in HbA1c. RESULTS: After 24 weeks, greater reductions in HbA1c from baseline (67 mmol/mol; 8.3%) were seen with iGlarLixi (-21 mmol/mol; -1.9%) compared with iGlar (-16 mmol/mol; -1.4%; P < 0.0001) and Lixi (-10 mmol/mol; -0.9%; P < 0.0001). Greater proportions of participants achieved HbA1c <53 mmol/mol (<7%) with iGlarLixi versus iGlar or Lixi (79%, 60% and 30%, respectively), overall and as composite endpoints including weight and hypoglycaemia. iGlarLixi improved 2-hour postprandial glucose versus iGlar and Lixi and mitigated the weight gain seen with iGlar (least squares mean difference -1.1 kg; P < 0.0001). Documented ≤3.9 mmol/L (≤70 mg/dL) hypoglycaemia was similar between iGlarLixi and iGlar (both 3.38 events per participant-year). The incidence rates of nausea and vomiting were lower with iGlarLixi (14% and 6%) than Lixi (21% and 11%). CONCLUSIONS: iGlarLixi achieved significant HbA1c reductions, to near-normoglycaemic levels, compared with iGlar or Lixi, with no meaningful additional risk of hypoglycaemia and mitigated body weight gain versus iGlar, with fewer gastrointestinal adverse events versus Lixi. iGlarLixi with specifically adapted ratios may provide an efficacious and well-tolerated treatment option for Asian Pacific people with T2D.

Switching to iGlarLixi versus continuation of a daily or weekly glucagon-like peptide-1 receptor agonist (GLP-1 RA) in insufficiently controlled type 2 diabetes: A LixiLan-G trial subgroup analysis by HbA1c and GLP-1 RA use at screening.

AIM: In people with type 2 diabetes (T2D) requiring intensification beyond glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and oral antihyperglycaemic drugs (OADs), switching to iGlarLixi was shown to be efficacious and well-tolerated in the LixiLan-G trial. This exploratory analysis of LixiLan-G assessed the efficacy and safety of switching to iGlarLixi versus continuing GLP-1 RA therapy, stratified by screening HbA1c level (≥7.0 to ≤7.5 %; >7.5 to ≤8.0 %; >8.0 to ≤9.0 % [≥53 to ≤58 mmol/mol; >58 to ≤64 mmol/mol; >64 to ≤75 mmol/mol]) and previous GLP-1 RA regimen at screening (once/twice daily or once weekly). MATERIALS AND METHODS: Endpoints for all subgroups included: change in HbA1c, achievement of HbA1c <7 % and hypoglycaemia events. Adverse events and changes in fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (PPG), 2-hour PPG excursion and weight were analysed according to previous GLP-1 RA regimen. RESULTS: Switching to iGlarLixi in all subgroups resulted in significantly greater reductions in HbA1c and proportions of participants reaching HbA1c <7 % (including with no documented hypoglycaemia) at Week 26 compared with continued GLP-1 RA treatment. Switching to iGlarLixi also led to significantly greater reductions in FPG, 2-hour PPG, and 2-hour PPG excursion, irrespective of previous GLP-1 RA regimen. Rates of hypoglycaemia were low, but slightly higher in those who switched to iGlarLixi for all subgroups. Modest weight gain was seen with iGlarLixi, irrespective of previous GLP-1 RA regimen. CONCLUSIONS: Switching to iGlarLixi improved glycaemic control, regardless of screening HbA1c or previous GLP-1 RA type, offering a simple, efficacious and well-tolerated treatment intensification option for people with T2D inadequately controlled by GLP-1 RAs and OADs.

Impact of disease duration and ß-cell reserve on the efficacy of switching to iGlarLixi in adults with type 2 diabetes on glucagon-like peptide-1 receptor agonist therapy: Exploratory analyses from the LixiLan-G trial.

AIM: To evaluate the efficacy of iGlarLixi by C-peptide levels and duration of diabetes in an exploratory analysis of the LixiLan-G study. METHODS: LixiLan-G was a 26-week, randomized, open-label study in adults with type diabetes (T2D) inadequately controlled while on a glucagon-like peptide-1 receptor agonist (GLP-1 RA), with metformin, with or without pioglitazone and/or a sodium-glucose co-transporter-2 inhibitor. This analysis investigated the efficacy of switching to iGlarLixi by fasting baseline quartile C-peptide levels and baseline quartile of duration of T2D compared with continued GLP-1 RA use. RESULTS: Change in glycated hemoglobin (HbA1c) from baseline to week 26 was significantly greater with iGlarLixi compared with continued GLP-1 RAs across all fasting C-peptide quartiles (-1.00% to -1.06% vs. -0.23% to -0.54% range, respectively) and irrespective of all T2D duration quartiles (-0.94% to -1.07% vs. -0.25% to -0.50% range). A significantly greater proportion of participants in the iGlarLixi arm achieved an HbA1c of <7% across all C-peptide quartiles (51%-73% range) than in the GLP-1 RA arm (19%-32% range). The greatest reductions in HbA1c in participants receiving iGlarLixi were observed in those with the shortest duration of disease, although consistently greater than reductions observed with continued GLP-1 RAs. Reductions in HbA1c were comparable across C-peptide quartiles within the iGlarLixi arm. CONCLUSIONS: The results of this study suggest that iGlarLixi is an effective treatment option, irrespective of C-peptide levels or duration of diabetes, in adults with insufficiently controlled T2D receiving GLP-1 RAs.

Diurnal glucose exposure profiles of patients treated with lixisenatide before breakfast or the main meal of the day: An analysis using continuous glucose monitoring.

BACKGROUND: In the parent study of this analysis, patients with type 2 diabetes received lixisenatide before breakfast or the main meal of the day. This substudy was designed to examine the effect of lixisenatide administered before breakfast or the main meal of the day on continuously assessed 24-hour patient glucose profiles. METHODS: A subset of patients from the parent study underwent 2 14-day periods of continuous glucose monitoring (CGM) at the start and end of the 24-week study. Ambulatory glucose profile analysis was used to measure changes over time in detailed aspects of the glucose profiles. The breakfast group consumed a standardized meal during both CGM periods to determine change in 4-hour glycemic response. RESULTS: Data were available for 69 patients in the substudy, 40 from the original breakfast group and 29 from the main meal group. Between baseline and end of study, mean (standard deviation) total glucose exposure decreased from 4198.1 (652.3) to 3681.2 (699.6) mg/dL*24 h in the breakfast group (P < .0001) and from 4127.9 (876.8) to 3880.9 (1165.0) mg/dL*24 h in the main meal group (P = .0224). For patients included in the substudy, HbA1c decreased by approximately 0.6% in both groups. Mean (standard deviation) 4-hour total glucose exposure fell by 168.9 (158.4) mg/dL*4 h (P < .0001) from baseline. CONCLUSIONS: This analysis demonstrates that lixisenatide has beneficial effects on components of the 24-hour glucose profile, which endure beyond the meal at which it is administered. Continuous glucose monitoring analysis detects changes not captured using HbA1c alone.

Impact of baseline glycated haemoglobin, diabetes duration and body mass index on clinical outcomes in the LixiLan-O trial testing a titratable fixed-ratio combination of insulin glargine/lixisenatide (iGlarLixi) vs insulin glargine and lixisenatide monocomponents.

To determine whether baseline characteristics had an impact on clinical outcomes in the LixiLan-O trial (N = 1170), we compared the efficacy and safety of iGlarLixi, a titratable fixed-ratio combination of insulin glargine 100 U (iGlar) and lixisenatide (Lixi) with iGlar or Lixi alone in patients with uncontrolled type 2 diabetes mellitus (T2DM) on oral therapy. Subgroups according to baseline glycated haemoglobin (HbA1c; <8% or ≥8% [<64 or ≥64 mmol/mol]), T2DM disease duration (<7 or ≥7 years) and body mass index (BMI; <30 or ≥30 kg/m2 ) were investigated. In all subpopulations, iGlarLixi was consistently statistically superior to iGlar and Lixi alone in reducing HbA1c from baseline to week 30; higher proportions of patients achieved HbA1c <7% (<53 mmol/mol) with iGlarLixi vs iGlar and Lixi alone. Compared with iGlar, iGlarLixi resulted in a substantial decrease in 2-hour postprandial plasma glucose levels, and mitigation of weight gain, with no differences among subpopulations in incidence of symptomatic hypoglycaemia. iGlarLixi consistently improved glycaemic control compared with iGlar and Lixi alone, without weight gain or increase in hypoglycaemic risk compared with iGlar in the subpopulations tested, regardless of baseline HbA1c, disease duration and BMI.

Consistent findings in glycaemic control, body weight and hypoglycaemia with iGlarLixi (insulin glargine/lixisenatide titratable fixed-ratio combination) vs insulin glargine across baseline HbA1c, BMI and diabetes duration categories in the LixiLan-L trial.

AIMS: To assess the impact of baseline characteristics on clinical outcomes in the LixiLan-L trial, a randomized open-label trial designed to evaluate the efficacy and safety of iGlarLixi, a novel fixed-ratio combination of insulin glargine 100 U (iGlar) plus lixisenatide, in comparison with iGlar over 30 weeks in a population of patients with type 2 diabetes mellitus (T2DM) inadequately controlled on a previous regimen of basal insulin alone or in combination with 1 or 2 oral glucose-lowering drugs. MATERIALS AND METHODS: In this exploratory analysis of LixiLan-L (N = 736), efficacy outcomes were assessed within population subgroups derived from the following baseline characteristics: glycated haemoglobin [HbA1c; <8%, ≥8% (<64, ≥64 mmol/mol)]; duration of T2DM (<10, ≥10 years); body mass index (<30, ≥30 kg/m2 ). Furthermore, the incidence of symptomatic hypoglycaemia with plasma glucose ≤3.9 mmol/L (≤70 mg/dL) was also analysed according to the same subgroups. RESULTS: Compared with the iGlar treatment group, patients treated with iGlarLixi showed consistently greater reductions in HbA1c during the treatment period, with higher percentages of patients achieving the HbA1c target level of <7% (<53 mmol/mol) in all of the subpopulations tested (P < .0001 for all), having consistent mitigation of body weight gain and with no major differences in the incidence of hypoglycaemia. CONCLUSIONS: iGlarLixi consistently improved glycaemic control compared with iGlar in all baseline characteristic subgroups of patients with T2DM inadequately controlled with insulin, including difficult-to-treat subgroups of patients with long duration of diabetes, obesity and high HbA1c. Clinical trial number: NCT02058160 (clinicaltrials.gov).

Concomitant iGlarLixi and Sodium-Glucose Co-transporter-2 Inhibitor Therapy in Adults with Type 2 Diabetes: LixiLan-G Trial and Real-World Evidence Results.

INTRODUCTION: iGlarLixi, the once-daily fixed-ratio combination of insulin glargine 100 U/ml and lixisenatide, robustly improves glycaemic control in adults with type 2 diabetes irrespective of previous treatment [oral antihyperglycaemic drugs (OADs), basal insulin or glucagon-like peptide-1 receptor agonists (GLP-1 RAs)]. Sodium-glucose co-transporter-2 inhibitors (SGLT2is) are a recommended treatment option for people with type 2 diabetes with cardiovascular disease, kidney disease and/or heart failure because of their cardio- and renoprotective benefits. Herein, we assessed the effects of concomitant iGlarLixi and SGLT2i therapy. METHODS: We conducted subgroup analyses according to SGLT2i use in: (1) adults with suboptimally controlled type 2 diabetes on GLP-1 RAs and OADs switching to iGlarLixi in the 26-week LixiLan-G randomised controlled trial (RCT; NCT02787551) and (2) adults switching to or adding iGlarLixi in a 6-month, retrospective real-world evidence (RWE) observational study using data from the US Optum-Humedica electronic medical records database. Changes in HbA1c and hypoglycaemia prevalence and event rates were assessed. RESULTS: There were no major differences in baseline characteristics for those who initiated iGlarLixi while already using SGLT2i (n = 346) and those initiating iGlarLixi without concomitant SGLT2i therapy (n = 1285). HbA1c reductions from baseline to time of assessment and hypoglycaemia prevalence and event rates were similar for iGlarLixi users regardless of SGLT2i therapy. CONCLUSION: Evidence from an RCT and an RWE analysis supports the efficacy/effectiveness and safety of iGlarLixi when used concomitantly with SGLT2i. TRIAL REGISTRATION: NCT02787551.

People with type 2 diabetes require glucose-lowering drugs to attain and maintain blood glucose control, with many eventually requiring injectable therapies. iGlarLixi combines two injectable therapies (basal insulin glargine and a glucagon-like peptide-1 receptor agonist, lixisenatide) into a single fixed-ratio daily injection and has previously been shown to provide robust improvements in blood glucose control. However, previous studies have not assessed the potential effect that simultaneous use of sodium-glucose co-transporter-2 inhibitor (SGLT2i) therapy may have on iGlarLixi therapy. This is of interest because SGLT2is are a widely used oral blood-glucose-lowering therapy that also have a beneficial effect in people with type 2 diabetes who have cardiovascular or kidney disease or have risk factors for the development or progression of these conditions. Therefore, this study assessed whether there were relevant differences in terms of blood glucose control and safety when initiating iGlarLixi in people treated with SGLT2i versus initiating iGlarLixi in people not receiving SGLT2i. Results showed that iGlarLixi provided similarly good glucose control and safety profiles, regardless of whether SGLT2is were used or not, thereby supporting the simultaneous use of these two therapies.

Cost-Effectiveness of iGlarLixi Versus iDegLira in Type 2 Diabetes Mellitus Inadequately Controlled by GLP-1 Receptor Agonists and Oral Antihyperglycemic Therapy.

INTRODUCTION: The fixed-ratio combinations (FRCs) of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and basal insulin, insulin glargine 100 U/mL plus lixisenatide (iGlarLixi), and insulin degludec plus liraglutide (iDegLira), have demonstrated safety and efficacy in patients with type 2 diabetes mellitus (T2DM) inadequately controlled on GLP-1 RAs. However, a comparative cost-effectiveness analysis between these FRCs from a UK Health Service perspective has not been conducted. METHODS: The IQVIA Core Diabetes Model was used to estimate lifetime costs and outcomes in patients with T2DM receiving iGlarLixi (based on the LixiLan-G trial) versus iDegLira (based on relative treatment effects from an indirect treatment comparison using data from DUAL III). Utilities, medical costs, and costs of diabetes-related complications were derived from literature. Model outputs included costs and quality-adjusted life years (QALYs). Incremental cost-effectiveness ratios were calculated with a local willingness-to-pay threshold of £20,000 per QALY. Extensive scenario, one-way sensitivity, and probabilistic sensitivity analyses were conducted to evaluate the robustness of the model. RESULTS: iGlarLixi was less costly (iGlarLixi, £30,011; iDegLira, £40,742), owing to lower acquisition costs, and similar in terms of QALYs gained (iGlarLixi, 8.437; iDegLira, 8.422). Extensive scenario and sensitivity analyses supported the base case findings. CONCLUSION: In patients with T2DM and inadequate glycemic control despite GLP-1 RAs, use of iGlarLixi was associated with substantial cost savings and comparable utility outcomes. iGlarLixi can be considered as cost-effective versus iDegLira from the UK Health Service perspective.

Durable Effects of iGlarLixi Up to 52 Weeks in Type 2 Diabetes: The LixiLan-G Extension Study.

OBJECTIVE: In the LixiLan-G trial, switching to iGlarLixi, a once-daily titratable fixed-ratio combination of insulin glargine 100 units/mL and the glucagon-like peptide 1 receptor agonist (GLP-1 RA) lixisenatide, improved glucose control in type 2 diabetes uncontrolled with GLP-1 RAs over 26 weeks versus continuing prior GLP-1 RA. A prespecified, 26-week, single-arm extension of LixiLan-G aimed to determine the durability of iGlarLixi efficacy and safety over 52 weeks. RESEARCH DESIGN AND METHODS: Participants with type 2 diabetes uncontrolled by GLP-1 RAs (glycated hemoglobin [HbA1c] 7-9% [53-75 mmol/mol]) were initially randomized to switch to iGlarLixi or continue prior GLP-1 RA. Those randomized to iGlarLixi who completed the 26-week primary end point period could continue iGlarLixi open-label treatment over a 26-week extension to assess durability of efficacy and safety. RESULTS: Glycemic control achieved with iGlarLixi at week 26 (mean HbA1c 6.7% [50 mmol/mol]) was maintained at week 52 (mean HbA1c 6.7% [50 mmol/mol]; mean ± SD change from baseline at week 52: -1.0 ± 0.9% [11 ± 10 mmol/mol]). Proportions of participants reaching HbA1c <7% (53 mmol/mol) with iGlarLixi were similar at week 26 (62%) and 52 (64%), as were those reaching this target without documented symptomatic (<3.0 mmol/L) hypoglycemia (57% and 58%). Safety of iGlarLixi was similar at weeks 26 and 52, with low rates of documented symptomatic hypoglycemia and gastrointestinal events. CONCLUSIONS: The efficacy and safety of iGlarLixi at the end of the 26-week randomized treatment period was maintained over the 26-week extension period in the LixiLan-G trial.

Impact of dose capping in insulin glargine/lixisenatide fixed-ratio combination trials in patients with type 2 diabetes.

OBJECTIVE: The LixiLan clinical trials of insulin glargine (iGlar)/lixisenatide fixed-ratio combination (iGlarLixi) investigated the safety and efficacy of iGlarLixi versus iGlar: LixiLan-O (NCT02058147) in patients with type 2 diabetes (T2D) inadequately controlled on oral antidiabetes drugs (OADs) and LixiLan-L (NCT02058160) in patients with T2D inadequately controlled on basal insulin ± OADs. In these two trials, both iGlar and iGlarLixi were titrated to a maximum (capped) dose of 60 units. We evaluated whether this may have affected the reported glycemic efficacy of iGlar, and the glycemic differences observed between treatment with iGlarLixi and iGlar. METHODS: The efficacy of iGlar under uncapped conditions was simulated in a two-step approach. First, a model characterizing the relationship between iGlar dose and fasting self-measured plasma glucose (f-SMPG) was developed. Then, the relationship between glycated hemoglobin A1c (A1C) and f-SMPG was established to translate simulated f-SMPG responses to A1C responses. RESULTS: Most patients achieved stable f-SMPG at ∼60 units/day, with no further reduction with increasing insulin dose. In comparisons of observed/capped and simulated/uncapped changes in mean A1C from baseline to Week 30, iGlarLixi consistently demonstrated treatment benefit compared with iGlar. Uncapping resulted in a slightly higher mean iGlar dose in both LixiLan-O (+0.72 units) and LixiLan-L (+2.1 units), without marked impact on f-SMPG or A1C change from baseline. CONCLUSION: Uncapping the iGlar dose in LixiLan-O and LixiLan-L would not have led to significant improvements in mean A1C reduction in the iGlar arm, supporting the conclusion that iGlarLixi provides additional, clinically relevant glycemic control versus iGlar alone.

Efficacy and safety of insulin glargine/lixisenatide (iGlarLixi) fixed-ratio combination in older adults with type 2 diabetes.

AIMS: This study assessed the efficacy and safety of iGlarLixi (a titratable, fixed-ratio combination of insulin glargine [iGlar] plus lixisenatide) in older patients with type 2 diabetes. METHODS: This post hoc analysis used patient-level data from patients aged ≥65 years from the phase III LixiLan-O and LixiLan-L studies, which compared iGlarLixi with iGlar and lixisenatide (LixiLan-O only). Efficacy endpoints were changes in glycated hemoglobin A1C, fasting plasma glucose, postprandial glucose, weight, and achievement of A1C <7.0% (53 mmol/mol). Safety measures included incidence of documented symptomatic hypoglycemia (defined as typical symptoms of hypoglycemia plus self-measured plasma glucose ≤70 mg/dL [3.9 mmol/L]), severe hypoglycemia (requiring assistance of another person), and incidence of gastrointestinal adverse events. Results were compared with those from patients aged <65 years. RESULTS: In both trials, older patients treated with iGlarLixi achieved significantly greater reductions in A1C at Week 30 than comparators. Treatment with iGlarLixi mitigated insulin-associated weight gain and lixisenatide-associated gastrointestinal events. Results were largely comparable between patients aged ≥65 versus <65 years. CONCLUSIONS: iGlarLixi provides significant improvements in glycemic control in patients aged ≥65 years without increasing hypoglycemia risk. As a once-daily injection, it simplifies treatment regimens and may contribute to improved adherence in this patient population.

Switching to iGlarLixi Versus Continuing Daily or Weekly GLP-1 RA in Type 2 Diabetes Inadequately Controlled by GLP-1 RA and Oral Antihyperglycemic Therapy: The LixiLan-G Randomized Clinical Trial.

OBJECTIVE: Fixed-ratio combinations of basal insulin plus glucagon-like peptide 1 receptor agonist (GLP-1 RA) allow concomitant administration of two proven complementary injectable therapies for type 2 diabetes. This study investigated switching to a titratable fixed-ratio combination of insulin glargine plus lixisenatide (iGlarLixi) in patients with type 2 diabetes receiving daily or weekly GLP-1 RA therapy. RESEARCH DESIGN AND METHODS: LixiLan-G, a randomized, open-label, 26-week trial, compared switching to iGlarLixi versus continuing prior GLP-1 RA in patients with type 2 diabetes and HbA1c 7-9% (53-75 mmol/mol) taking maximum tolerated doses of a GLP-1 RA daily (60% on liraglutide once daily or exenatide twice daily) or weekly (40% on dulaglutide, exenatide extended release, or albiglutide) with metformin with or without pioglitazone and with or without sodium-glucose cotransporter 2 inhibitors. Adherence to randomized treatment was closely monitored throughout the study. RESULTS: iGlarLixi (n = 257) reduced HbA1c more than continued GLP-1 RA therapy (n = 257) from a baseline 7.8% (62 mmol/mol) in both to 6.7% (50 mmol/mol) and 7.4% (57 mmol/mol), respectively, at 26 weeks (least squares mean difference -0.6%; P < 0.0001). More iGlarLixi patients achieved HbA1c <7% (53 mmol/mol) (62% vs. 26%; P < 0.0001) and the composite of HbA1c <7% without documented symptomatic hypoglycemia (<54 mg/dL). Nausea and vomiting rates as well as numbers of documented symptomatic hypoglycemia events per patient-year were generally low but greater with iGlarLixi versus continued GLP-1 RA therapy. CONCLUSIONS: Switching to iGlarLixi improves glucose control for patients with type 2 diabetes insufficiently controlled on a maximum tolerated dose of a GLP-1 RA plus oral antihyperglycemic agents.

iGlarLixi Reduces Glycated Hemoglobin to a Greater Extent Than Basal Insulin Regardless of Levels at Screening: Post Hoc Analysis of LixiLan-L.

INTRODUCTION: The treatment of patients with type 2 diabetes uncontrolled on basal insulin and oral glucose-lowering drugs was investigated previously in the LixiLan-L trial. In the LixiLan-L trial, patients experienced a 6-week run-in with insulin glargine U100 (iGlar) as part of the screening phase, followed by treatment with a fixed-ratio combination of iGlar + lixisenatide (iGlarLixi) or iGlar alone over 30 weeks. In the study reported here, we investigated the achievement of glycemic control in those who completed the 30-week LixiLan-L trial, as assessed by change in glycated hemoglobin (HbA1c) levels from screening, both for the overall category and for screening HbA1c subcategories. METHODS: This post hoc analysis of the LixiLan-L trial included both the screening phase and the treatment period for 30-week completers and evaluated the change in HbA1c from screening to Week 30, patients reaching HbA1c < 7% at Week 30, and iGlar and lixisenatide (Lixi) doses at Week 30 overall and according to HbA1c subcategory at screening (HbA1c ≤ 8%, 8% < HbA1c ≤ 9%, and HbA1c > 9%). Documented symptomatic hypoglycemia during the treatment period was also assessed. RESULTS: HbA1c reductions (least squares mean) from screening to Week 30 were greater for iGlarLixi than iGlar, both overall (- 1.7 vs. - 1.1%) and in all subgroups (HbA1c ≤ 8%, 8% < HbA1c ≤ 9%, and HbA1c > 9%): - 1.1, - 1.4, - 2.4 (iGlarLixi) vs. - 0.5, - 1.0, - 1.8% (iGlar), respectively (all p < 0.0001). The end-of-treatment mean HbA1c level for iGlarLixi across all groups was < 7%. More patients achieved an HbA1c of < 7% with iGlarLixi than with iGlar, both overall (59.9 vs. 31.2%) and within each subgroup [74.2, 54.7, 52.2 (iGlarLixi) vs. 37.2, 31.6, 23.5% (iGlar), respectively]. A higher initial screening HbA1c corresponded with a greater mean reduction in HbA1c for both treatment strategies. In all HbA1c screening categories, the risk of hypoglycemia was not increased with iGlarLixi versus iGlar during the treatment phase. CONCLUSION: iGlarLixi controlled HbA1c levels more effectively than iGlar across all HbA1c screening subgroups and in the overall study population without increasing the risk of hypoglycemia.

Efficacy and Safety of LixiLan, a Titratable Fixed-Ratio Combination of Lixisenatide and Insulin Glargine, Versus Insulin Glargine in Type 2 Diabetes Inadequately Controlled on Metformin Monotherapy: The LixiLan Proof-of-Concept Randomized Trial.

OBJECTIVE: This study assessed the efficacy and safety of LixiLan, a fixed-ratio, titratable, combination of 2 units insulin glargine (Gla-100) and 1 µg lixisenatide administered once daily via a single pen, versus Gla-100 in insulin-naïve type 2 diabetes on metformin. RESEARCH DESIGN AND METHODS: Participants were randomized to once-daily LixiLan (n = 161) or Gla-100 (n = 162) for 24 weeks, while continuing metformin. LixiLan and Gla-100 were started at 10 units/5 µg and 10 units, respectively, and titrated based on the Gla-100 requirement according to fasting plasma glucose levels. The primary objective was to test noninferiority (upper bound of the 95% CI ≤0.4%) of LixiLan in reducing HbA1c; if met, statistical superiority was tested. Secondary objectives included body weight changes, hypoglycemia, and safety. RESULTS: Baseline characteristics (mean age 57 years, diabetes duration 6-7 years, BMI 32 kg/m(2)) were similar between groups. At week 24, mean HbA1c was reduced from 8.0% (64 mmol/mol) at baseline to 6.3% (45 mmol/mol) and 6.5% (48 mmol/mol) with LixiLan and Gla-100, respectively, establishing statistical noninferiority and superiority of LixiLan (least-squared mean [95% CI] difference: -0.17% [-0.31, -0.04] {-1.9 mmol/mol [-3.4, -0.4]}; P = 0.01). HbA1c <7.0% (<53 mmol/mol) was achieved in 84% and 78% of participants (nonsignificant), respectively. LixiLan improved 2-h postmeal plasma glucose versus Gla-100 (least-squared mean difference: -3.17 mmol/L [-57 mg/dL]; P < 0.0001). Body weight was reduced with LixiLan (-1 kg) and increased with Gla-100 (+0.5 kg; P < 0.0001), with no increase in hypoglycemic events (∼25% in each group). The incidence of nausea (7.5%) and vomiting (2.5%) was low with LixiLan. CONCLUSIONS: LixiLan achieved statistically significant reductions to near-normal HbA1c levels with weight loss and no increased hypoglycemic risk, compared with insulin glargine alone, and a low incidence of gastrointestinal adverse events in type 2 diabetes inadequately controlled on metformin.

Efficacy and Safety of LixiLan, a Titratable Fixed-Ratio Combination of Insulin Glargine Plus Lixisenatide in Type 2 Diabetes Inadequately Controlled on Basal Insulin and Metformin: The LixiLan-L Randomized Trial.

OBJECTIVE: This study was conducted to demonstrate the efficacy and safety of LixiLan (iGlarLixi), a novel, titratable, fixed-ratio combination of insulin glargine (iGlar) (100 units) and lixisenatide, compared with iGlar in patients with type 2 diabetes inadequately controlled on basal insulin with or without up to two oral glucose-lowering agents. RESEARCH DESIGN AND METHODS: After a 6-week run-in when iGlar was introduced and/or further titrated, and oral antidiabetic drugs other than metformin were stopped, 736 basal insulin-treated patients (mean diabetes duration 12 years, BMI 31 kg/m2) were randomized 1:1 to open-label, once-daily iGlarLixi or iGlar, both titrated to fasting plasma glucose <100 mg/dL (<5.6 mmol/L) up to a maximum dose of 60 units/day. The primary outcome was change in HbA1c levels at 30 weeks. RESULTS: HbA1c decreased from 8.5% (69 mmol/mol) to 8.1% (65 mmol/mol) during the run-in period. After randomization, iGlarLixi showed greater reductions in HbA1c from baseline compared with iGlar (-1.1% vs. -0.6%, P < 0.0001), reaching a mean final HbA1c of 6.9% (52 mmol/mol) compared with 7.5% (58 mmol/mol) for iGlar. HbA1c <7.0% (53 mmol/mol) was achieved in 55% of iGlarLixi patients compared with 30% on iGlar. Mean body weight decreased by 0.7 kg with iGlarLixi and increased by 0.7 kg with iGlar (1.4 kg difference, P < 0.0001). Documented symptomatic hypoglycemia (≤70 mg/dL) was comparable between groups. Mild gastrointestinal adverse effects were very low but more frequent with iGlarLixi. CONCLUSIONS: Compared with iGlar, a substantially higher proportion of iGlarLixi-treated patients achieved glycemic targets with a beneficial effect on body weight, no additional risk of hypoglycemia, and low levels of gastrointestinal adverse effects in inadequately controlled, basal insulin-treated, long-standing type 2 diabetes.
