All data are n (%) patients with events, unless otherwise stated.
↵**Defined as more than twice the upper limit of normal confirmed by repeat measurement.
↵*Any symptomatic hypoglycemia reported as clinically meaningful by the study investigator regardless of plasma glucose.
↵†P = 0.01 vs. lixisenatide (Fisher exact test; post hoc analysis).
↵‡P = 0.0001 vs. lixisenatide (Fisher exact test; post hoc analysis).
↵§Symptomatic hypoglycemia accompanied by glucose <3.3 mmol/L (<60 mg/dL) or prompt recovery with oral carbohydrate.
↵‖P = 0.0031 vs. lixisenatide (Fisher exact test; post hoc analysis).
↵¶Number of hypoglycemia events was analyzed using negative binomial regression with a log-link function and the logarithm of the time period for which a hypoglycemic episode was considered treatment-emergent as offset, with treatment, randomization strata of HbA1c, randomization strata of metformin use, and country as fixed effects.
↵#Plasma glucose <2.0 mmol/L (<36 mg/dL) or with prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration; 70% of patients receiving lixisenatide or insulin glulisine once daily administered their dose in the evening.
