Abstract

Abstract Background Using patient data from the GetGoal-Duo1, -L, and L-Asia trials, the objectives of this study were to evaluate and compare the impact of lixisenatide once-daily add-on treatment to basal insulin therapy ±oral antidiabetic drugs (OADs) among type 2 diabetes (T2DM) patients subdivided into groups, based on their baseline body mass indices (BMI). Methods Data of patients treated with lixisenatide were extracted from the modified intent-to-treat populations of the trials. Patients were subdivided into 4 groups based on baseline BMI category (BMIs <25, 25–<30, 30–<35, and ≥35 kg/m2 ). At the unadjusted data level, efficacy and safety endpoints were evaluated and compared among study cohorts. Additionally, multivariable regression analyses were used to specify key patient characteristics and then assess the adjusted outcomes. Results Of the 662 T2DM patients, the mean changes in HbA1c (−0.63 to −0.73 %, p = 0.88) and FPG levels (−3.9 to 3.2 mg/dL, p = 0.60) were not significantly different among the different BMI groups. The proportions of T2DM patients that achieved HbA1c <7 % ranged between 34.7 and 46.8 %. After adjusted for patient characteristics, T2DM patients in the lowest BMI group relative to those in the highest BMI group had a smaller reduction in HbA1c during the trial periods (difference: 0.32 %, confidence interval: 0.10, 0.53, p = 0.005) and were less likely to achieve HbA1c <7 %. Conclusions The findings of this analysis of the GetGoal clinical trials suggest that lixisenatide may be a good treatment option for optimizing glycemic control in patients unable to achieve their HbA1c target on basal insulin therapy ±OADs, regardless of BMI category.
