Efficacy and Safety of the Insulin Glargine/Lixisenatide Fixed Ratio Combination Versus Insulin Glargine in Patients With Type 2 Diabetes (LixiLan-India)

Inclusion criteria : * Patients with type 2 diabetes mellitus (T2DM) diagnosed for at least 1 year before the screening visit, * At screening: * Age should be ≥ 18 years of age to \< 65 years; * Glycosylated hemoglobin (HbA1c) at screening visit ≥ 7.5% or ≤ 10%; * Body mass index (BMI) ≥ 19 kg/m2 and ≤ 40 kg/m2. * Patients who have been treated with a basal insulin for at least 6 months before the screening visit, and who have been on a stable basal insulin regimen (ie, type of insulin and time/frequency of the injection), for at least 3 months before the screening visit. The stable total daily dose should be within the range of 15-40 U, both inclusive, on the day of screening, but individual fluctuations of ± 20% within 2 months prior to screening are acceptable. Exclusion criteria: * Use of oral or injectable glucose-lowering agents other than those stated in the inclusion criteria in the 3 months before screening. * Previous use of insulin regimen other than basal insulin eg, prandial or pre-mixed insulin (Note: Short term treatment due to intercurrent illness including gestational diabetes is allowed at the discretion of the investigator). * For patients taking metformin, any contraindication to metformin use, according to local labeling. * For patient not treated with metformin at screening: severe renal function impairment with an estimated glomerular filtration rate (eGFR) \<30 mL/min/1.73m2 or end-stage renal disease. * Personal or immediate family history of medullary thyroid cancer (MTC) or genetic condition that predisposes to MTC (eg, multiple endocrine neoplasia syndromes). * Clinically relevant history of gastrointestinal disease associated with prolonged nausea and vomiting, including (but not limited to): gastroparesis, unstable (ie, worsening) or not controlled (ie, prolonged nausea and vomiting) gastroesophageal reflux disease requiring medical treatment, within 6 months prior to the time of screening visit; or history of surgery affecting gastric emptying. * History of pancreatitis (unless pancreatitis was related to gallstones and cholecystectomy has been performed), pancreatitis during previous treatment with incretin therapies, chronic pancreatitis, pancreatectomy. * Average insulin glargine daily dose \<20 U or \>50 U calculated for the last 3 days before Visit 6. * Amylase and/or lipase \>3 upper limit normal (ULN) at Visit 5 (Week -1).
