Conditions: Type 2 Diabetes Mellitus
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 807
Healthy volunteers: no

Brief summary:
Primary Objective:

* To compare the efficacy of insulin glargine new formulation and Lantus in terms of change in HbA1c from baseline to endpoint (scheduled month 6) in adult participants with type 2 diabetes mellitus

Secondary Objectives:

* To compare the efficacy of insulin glargine new formulation and Lantus in terms of occurrence of nocturnal Hypoglycemia

Detailed description:
The maximum study duration was up to approximately 58 weeks per participant, consisting of:

* up to 2 week screening period
* 6-month comparative efficacy and safety treatment period
* 6-month comparative safety extension period
* 4-week safety follow-up period in a subset of participants
* a 3-month administration substudy period starting after completion of the 6-month study period for participants willing to in a subset of participants randomized to HOE901-U300

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: HOE901-U300 (new formulation of insulin glargine) intervention 2: Lantus (insulin glargine)
Intervention descriptions: intervention 1: HOE901-U300 (new insulin glargine 300 units per milliliter \[U/mL\]) subcutaneous (SC) injection once daily (evening) for 12 months on top of mealtime insulin analogue. Dose titration seeking fasting plasma glucose 4.4-5.6 millimole per liter (mmol/L) (80 - 100 milligram per deciliter \[mg/dL\]). After 6 months participants were proposed to participate to the administration substudy and to receive either HOE901-U300 once daily at intervals of 24 +/- 3 hours (adaptable dosing intervals) or to continue once daily injections of HOE901-U300 every 24 hours (fixed dosing intervals) up to Month 9. intervention 2: Lantus (HOE901-U100, insulin glargine 100 U/mL) SC injection once daily (evening) for 12 months on top of mealtime insulin analogue. Dose titration seeking fasting plasma glucose 4.4-5.6 mmol/L (80 - 100 mg/dL).
