The efficacy and safety of beinaglutide alone or in combination with insulin glargine in Chinese patients with type 2 diabetes mellitus who are inadequately controlled with oral antihyperglycemic therapy: A multicenter, open‐label, randomized trial

Abstract

Abstract Background To compare glycemic control in Chinese patients with type 2 diabetes mellitus (T2DM) whose blood glucose levels were inadequately controlled with oral antidiabetic drugs after beinaglutide alone or combined with insulin glargine (IGlar). Methods In this 16‐week multicenter, randomized clinical trial, 68 participants randomly received beinaglutide or IGlar for 8 weeks, then the two drugs in combination for 8 weeks. The primary outcomes were the proportion of individuals achieving their glycemic target and the change in glucose variability as measured with a continuous glucose monitoring system from baseline to 8 and 16 weeks. Results Both the beinaglutide and IGlar groups showed increased proportions achieving their glycemic target at 8 weeks, and the combination augmented the proportion reaching the glycated hemoglobin target from 25.42% at 8 weeks to 40.68% at 16 weeks. The beinaglutide group showed a significant reduction in body weight, body mass index, waist circumference, and systolic blood pressure. Beinaglutide elevated high‐density lipoprotein cholesterol by 0.08 mmol/L (95% confidence interval [CI], 0.00–0.16), and diminished low‐density lipoprotein cholesterol by 0.21 mmol/L (95% CI, 0.05–0.48), whereas IGlar showed no effect. Though IGlar was more efficient in lowering fasting plasma glucose than beinaglutide at comparable efficacies (to −1.57 mmol/L [95% CI, −2.60 to −0.54]), this difference was abolished in patients whose fasting C‐peptide was ≥0.9 ng/mL. Conclusion Beinaglutide exhibited a favorable hypoglycemic effect on patients with T2DM, and in combination with IGlar, glucose level was further decreased. Low fasting C‐peptide in patients may reduce the glycemic response to beinaglutide therapy. We recommend that C‐peptide levels be evaluated when using or switching to the novel glucagon‐like peptide‐1 receptor agonists beinaglutide. Trial Registration ClinicalTrials.gov: NCT03829891.
