Exenatide once weekly versus daily basal insulin as add-on treatment to metformin with or without a sulfonylurea: a retrospective pooled analysis in patients with poor glycemic control
Abstract
Basal insulin (b-INS) is typically the add-on treatment of choice for patients with poor glycemic control (ie, glycated hemoglobin [HbA1c] level ≥ 8.5%), but it is unclear whether b-INS is the best option. In this post hoc analysis, the efficacy and tolerability of exenatide once weekly (EQW) were compared with those of b-INS in patients with type 2 diabetes mellitus and a baseline HbA1c level 8.5% who were undergoing treatment with metformin ± a sulfonylurea. Data were pooled from two 26-week, randomized, controlled trials (EQW vs insulin glargine and EQW vs insulin detemir [EQW, N = 137; b-INS, N = 126]). Treatment with either EQW or b-INS for 26 weeks was associated with significant improvements in HbA1c level compared with baseline, although patients treated with EQW experienced a significantly greater decrease in HbA1c level than those treated with b-INS (least squares [LS] mean ± SE: -2.0% ± 0.08% vs -1.6% ± 0.08%; P = 0.0008). Treatment with EQW was associated with a weight loss of 2.4 kg ± 0.23 kg (LS mean ± SE), whereas treatment with b-INS was associated with a weight gain of 2.0 kg ± 0.24 kg (LS mean difference between groups, -4.4 kg ± 0.33; P < 0.0001). Patients in the EQW group were significantly more likely to achieve the composite endpoint of an HbA1c level < 7.0%, no weight gain, and no hypoglycemic events (defined as a blood glucose level < 54 mg/dL requiring self-treatment or assistance to resolve) than patients in the b-INS group (33.6% vs 3.2%; P <…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 137 participants or records.
