Conditions: Type 2 Diabetes Mellitus
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 505
Healthy volunteers: no

Brief summary:
Primary Objective:

To demonstrate non-inferiority of SAR342434 versus Humalog in glycated hemoglobin A1c (HbA1c) change from baseline to Week 26 in participants with type 2 diabetes mellitus (T2DM) also using insulin glargine.

Secondary Objectives:

To assess the immunogenicity of SAR342434 and Humalog in terms of positive/negative status and antibody titers at baseline and during the course of the study; To assess the relationship of anti-insulin antibodies with efficacy and safety. To assess the efficacy of SAR342434 and Humalog on: proportion of participants reaching target HbA1c \<7.0% and \<=6.5%, fasting plasma glucose (FPG) and self-measured plasma glucose (SMPG) profiles, and insulin dose.

To assess safety of SAR342434 and Humalog.

Detailed description:
The study will consist of a: up to 2 weeks screening period, 26-week treatment period, and 1-day follow-up period.

The maximum study duration will then be 28 weeks per participant and a 1-day safety follow-up.

Arms:
arm 1: SAR342434 100 Unit/mL (U/mL) before meals intake on top of once daily (QD) Insulin Glargine, up to Week 26. arm 2: Humalog 100 U/mL before meals intake on top of QD Insulin Glargine, up to Week 26.

Interventions: intervention 1: SAR342434 intervention 2: Humalog intervention 3: insulin glargine HOE901
Intervention descriptions: intervention 1: SAR342434 100 U/mL (dose range of 1 Unit to 80 Units) self-administered by subcutaneous (SC) injection, immediately (within 5 -10 minutes) before meals intake. Dose adjusted to achieve 2 hour post prandial glucose (PPG) in range of 6.7 to 8.9 mmol/L (120 to 160 mg/dL) while avoiding hypoglycemia. intervention 2: Humalog 100 U/ml (dose range of 1 unit to 60 units) self-administered by SC injection, immediately (within 5-10 minutes) before meals intake. Dose adjusted to achieve a 2 hour PPG in range of 6.7 to 8.9 mmol/L (120 to 160 mg/dL) while avoiding hypoglycemia. intervention 3: Insulin glargine 100 U/mL injected QD subcutaneously consistent with the local label. Doses adjusted to achieve glycemic target for fasting, preprandial plasma glucose (SMPG) between 4.4 to 7.2 mmol/L (80 to 130 mg/dL) without hypoglycemia.
