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.

ABSTRACT: 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?

Project description:ObjectiveThis 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 methodsParticipants 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.ResultsBaseline 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.ConclusionsLixiLan 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.

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.
