Insulin glargine/lixisenatide fixed-ratio combination improves glycaemic variability and control without increasing hypoglycaemia.

ABSTRACT: Maintaining optimal glycaemic control reduces the risk of micro- and macrovascular complications in patients with type 2 diabetes. Typically, glycaemic control is based on glycated haemoglobin (HbA1c) as a measure of mean glucose concentration; however, this marker does not accurately reflect glycaemic variability (GV), which is characterized by the amplitude, frequency and duration of hypo- and hyperglycaemic fluctuations. In the present study, we analysed data from the LixiLan-O trial, which compared iGlarLixi, a titratable fixed-ratio combination of the glucagon-like peptide-1 receptor agonist lixisenatide (Lixi) and long-acting basal insulin glargine 100 units/mL (iGlar), with its individual components, and the LixiLan-L trial, which compared iGlarLixi with iGlar. The GV features that were measured were mean and SD of self-measured plasma glucose (SMPG), high blood glucose index (HBGI) and low blood glucose index, area under the SMPG curve for each patient (AUCn), mean absolute glucose (MAG) and mean amplitude of glycaemic excursions (MAGE). By week 30, iGlarLixi improved all GV markers from baseline, with no increased hypoglycaemia risk. Significant improvements were observed in SMPG, SD of SMPG, HBGI, AUCn, MAG and MAGE compared with iGlar, and in SMPG, HBGI and AUCn, compared with Lixi.

Project description:IntroductioniGlarLixi is a titratable, fixed-ratio combination of insulin glargine (iGlar, 100 units/ml) and the glucagon-like peptide-1 receptor agonist lixisenatide for the treatment of patients with type 2 diabetes. This post hoc analysis of the phase 3 LixiLan-L trial (NCT02058160) investigated baseline characteristics, glycemic control, and safety outcomes in participants who received the study-specified maximum dose (60 units/day) of iGlarLixi or iGlar vs. those who received < 60 units/day.MethodsOutcomes were compared for participants receiving 60 or < 60 units/day at week 30. Endpoints analyzed included change in A1C, fasting plasma glucose (FPG), 2-h postprandial glucose (2-h PPG), body weight, proportion of participants achieving A1C < 7.0%, proportion of participants receiving rescue therapy, documented symptomatic hypoglycemia, and gastrointestinal adverse event (GI AE) incidence.ResultsBy week 30, 27% (iGlarLixi) and 31% (iGlar) of participants received the maximum dose. Participants on 60 vs. < 60 units/day were younger and had higher body weight, body mass index (BMI), FPG, and baseline insulin dose. In both dose groups, A1C change from baseline was significantly greater with iGlarLixi vs. iGlar, and more participants treated with iGlarLixi vs. iGlar achieved A1C < 7.0%. No significant differences were observed in change from baseline for A1C, FPG, 2-h PPG, or GI AE incidence between insulin dose groups, regardless of treatment. In both treatment arms, incidence of symptomatic hypoglycemia was lower in participants receiving 60 units/day vs. those receiving < 60 units/day. Participants treated with iGlarLixi (< 60 or 60 units/day) had modest weight loss over 30 weeks vs. an increase in weight compared with iGlar.ConclusionsMaximum doses of iGlarLixi were required in participants with a more insulin-resistant clinical phenotype (younger, higher BMI, FPG, and insulin doses). Benefits were observed with iGlarLixi vs. iGlar, even at 60 units/day, with more participants achieving glycemic goals, no increase in symptomatic hypoglycemia, and a modest reduction in body weight.FundingSanofi US, Inc.

Project description:ObjectiveTo assess the efficacy and safety of iGlarLixi (titratable fixed-ratio combination of insulin glargine (iGlar) and lixisenatide) in patients with type 2 diabetes (T2D) living in North America (NA; USA and Canada) compared with the rest of the world (RoW).Research design and methodsPost hoc analysis included patient-level data from 509 sites/centers across two phase III trials: LixiLan-O (NCT02058147; insulin-naive patients; NA, n=371; RoW, n=796) and LixiLan-L (NCT02058160; inadequately controlled patients on basal insulin; NA, n=196; RoW, n=535). Efficacy outcomes were: change from baseline to Week 30 in glycated hemoglobin (HbA1c), postprandial glucose (PPG), PPG excursions, fasting plasma glucose (FPG) and body weight; proportion of patients achieving HbA1c <42 mmol/mol (<7.0%); proportion of patients achieving composite endpoint: HbA1c <42 mmol/mol (<7.0%), no weight gain or symptomatic hypoglycemia (blood glucose ≤3.9 mmol/L (≤70 mg/dL)). Safety endpoints included incidence of documented symptomatic hypoglycemia and gastrointestinal (GI) adverse events.ResultsSignificantly larger reductions (p≤0.003) in HbA1c from baseline to Week 30 were achieved with iGlarLixi, compared with iGlar or lixisenatide, in NA and RoW patients in LixiLan-O (iGlarLixi vs iGlar: -0.31 and -0.29, respectively; iGlarLixi vs lixisenatide: -0.84 and -0.69, respectively) and in LixiLan-L (iGlarLixi vs iGlar: -0.5 and -0.51, respectively). Documented symptomatic hypoglycemia was similar between NA and RoW patients. iGlarLixi resulted in significant weight benefits versus iGlar (change from baseline -1.58 and -1.29 kg for NA and RoW patients, respectively; p<0.001). GI adverse events were similar for iGlarLixi and iGlar, but significantly higher for lixisenatide.ConclusionsiGlarLixi improved glycemic parameters versus iGlar or lixisenatide alone in both NA and RoW patients, with beneficial weight effects versus iGlar. iGlarLixi treatment responses, hypoglycemia risk and GI adverse events in NA patients were comparable with patients in the RoW.Trial registryClinicaltrials.gov NCT02058147 and NCT02058160.
