OBJECTIVE To assess the efficacy and safety of a 1:1 fixed-ratio combination of insulin glargine and lixisenatide (iGlarLixi) versus lixisenatide (Lixi) in insulin-naive Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on oral antidiabetic drugs (OADs). RESEARCH DESIGN AND METHODS In this phase 3, open-label, multicenter trial, 321 patients with HbA1c≥7.5 to ≤10.0% (58–86 mmol/mol) and fasting plasma glucose (FPG) ≤13.8 mmol/L (250 mg/dL) were randomized 1:1 to iGlarLixi or Lixi for 52 weeks. The primary end point was change in HbA1c at week 26. RESULTS Change in HbA1c from baseline to week 26 was significantly greater with iGlarLixi (−1.58% [−17.3 mmol/mol]) than with Lixi (−0.51% [−5.6 mmol/mol]), confirming the superiority of iGlarLixi (least squares [LS] mean difference −1.07% [−11.7 mmol/mol], P &amp;lt; 0.0001). At week 26, significantly greater proportions of patients treated with iGlarLixi reached HbA1c &amp;lt;7% (53 mmol/mol) (65.2% vs. 19.4%; P &amp;lt; 0.0001), and FPG reductions were greater with iGlarLixi than Lixi (LS mean difference −2.29 mmol/L [−41.23 mg/dL], P &amp;lt; 0.0001). Incidence of documented symptomatic hypoglycemia (≤3.9 mmol/L [70 mg/dL]) was higher with iGlarLixi (13.0% vs. 2.5%) through week 26, with no severe hypoglycemic events in either group. Incidence of gastrointestinal events through week 52 was lower with iGlarLixi (36.0% vs. 50.0%), and rates of treatment-emergent adverse events were similar. CONCLUSIONS This phase 3 study demonstrated superior glycemic control and fewer gastrointestinal adverse events with iGlarLixi than with Lixi, which may support it as a new treatment option for Japanese patients with T2DM that is inadequately controlled with OADs.
