Conditions
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.
Interventions
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.
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.
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.

Participant flow
Recruitment details
The study was conducted at 103 centers in 12 countries. A total of 707 participants were screened between 14 January 2015 and 24 July 2015, of which 202 were screen failures. Screen failures were mainly due to glycated hemoglobin (HbA1c) level \<6.5% or \>10% at screening visit.
Pre-assignment details
A total of 505 participants were randomized and treated in the study. Randomization was stratified by HbA1c at the screening visit (\<8%, \>=8%) and prior use of Humalog (Yes, No). Assignment to arms was done centrally using interactive voice/web response system in 1:1 ratio (SAR342434: Humalog).
