Safety and Efficacy of Biosimilar Insulin Glargine (Basaglar) in Indian Patients with Type 2 Diabetes Mellitus: Results from a Multicenter, Open-Label, Single-Arm, Phase 4 Trial (ABEX).

BACKGROUND

Basaglar®, a biosimilar of glargine, was approved in India for the treatment of diabetes in patients aged >2 years. The efficacy and safety of biosimilar insulin glargine (Basaglar) have been previously established in Phase 3 clinical trials, ELEMENT-1, -2, and -5. This study assessed the safety and efficacy of Basaglar in Indian patients with type 2 diabetes mellitus (T2DM).

MATERIALS AND

METHODS

This multicenter, open-label, single-arm, phase 4 trial included Indian patients with insulin-naïve T2DM with glycated hemoglobin A1c (HbA1c) ≥7.0 to <11.0% who were receiving ≥2 oral antihyperglycemic drugs and/or a glucagon-like peptide-1-receptor agonist. Patients received Basaglar once daily for 24 weeks, excluding 4 weeks of safety follow-up. The primary endpoint was the incidence of total hypoglycemic events [blood glucose (BG) ≤54 mg/dL (≤3.0 mmol/L)] at week 24.

RESULTS

Of the 259 patients enrolled, 64.1% were males, had mean [standard deviation (SD)] age 52.1 (11.38) years, and had diabetes for mean (SD) 6.75 (5.16) years. The mean HbA1c (SD) levels significantly improved from baseline to week 24 [-1.03 (1.554); p <0.0001] and Basaglar titration doubled from baseline. Total hypoglycemic events were reported in 10 (3.86%), 7 (2.70%), and 4 (1.54%) patients during weeks 0-24, 0-12, and 12-24, respectively. Ten patients (3.90%) reported 12 adverse events (AE; 11 mild and moderate, one severe). One death, unrelated to Basaglar, was reported.

CONCLUSION

Basaglar was well tolerated with few hypoglycemic events and significantly reduced HbA1c and BG from baseline in Indian insulin-naïve patients with T2DM.
