Abstract

Aims: Demonstrate superiority of insulin glargine (±glulisine) strategy versus premixed insulin strategy for percentage of patients reaching HbA1c <7% (<53 mmol/mol) at study end without any documented symptomatic hypoglycemia (bloof glucose [BG] ≤3.1 mmol/L) in type 2 diabetes (T2DM) patients failing oral agents.

Methods: This 24-week, open-label, multinational trial randomized patients to glargine OD or premix OD or BID, continuing metformin ± insulin secretagogue (IS). Second premix injection could be added any time; glulisine could be added with main meal in glargine OD patients with HbA1c ≥7% and fasting blood glucose (FBG) <7 mmol/L at week 12. IS was stopped with any second injection. Insulin titration targeted FBG ≤5.6 mmol/L.

Results: Modified intent-to-treat population comprised 923 patients (glargine, 462; premix, 461). Baseline characteristics were similar (mean T2DM duration: 9 years; HbA1c: 8.7% (72 mmol/mol); FBG: 10.4 mmol/L). Primary endpoint was achieved by 33.2% of glargine (±glulisine) and 31.4% of premix patients. Superiority was not demonstrated, but non-inferiority was (pre-specified margin: 25% of premix rate). More patients using premix achieved target (52.6% vs. 43.2%, p=0.005); symptomatic hypoglycemia was less with glargine (1.17 vs. 2.93 events/patient-year).

Conclusions: Glargine (±glulisine) and premix strategies resulted in similar percentages of well-controlled patients without hypoglycemia, with more patients achieving target HbA1c with premix whereas overall symptomatic hypoglycemia was less with glargine.
