Comparison of the Safety and Efficacy of HOE901-U300 With Lantus in Older Patients With Type2 Diabetes Insufficiently Controlled on Their Current Antidiabetic Medications

Primary Objective: To demonstrate the non-inferiority of H0E901-U300 to Lantus, in change of glycated hemoglobin A1c (HbA1c). Secondary Objectives: To demonstrate the superiority of H0E901-U300 in comparison with Lantus in: * Percentage of participants with at least one severe and/or confirmed (by plasma glucose ≤70mg/dL \[3.9mmol/L\]) hypoglycemia event from 22:00 to 08:59 next morning * Percentage of participants with at least one nocturnal (from 00:00-05:59) severe and/or confirmed (≤70mg/dL \[3.9mmol/L\]) hypoglycemia event * Percentage of participants with at least one severe and/or confirmed (by plasma glucose ≤70mg/dL \[3.9mmol/L\]) hypoglycemia event occurring at any time of day * HbA1c change
