Safety Assessment of SAR341402 and NovoLog® Used in Continuous Subcutaneous Insulin Infusion for Type 1 Diabetes Mellitus Patients

Primary Objective: \- To assess the safety of SAR341402 and NovoLog® when used in external insulin pumps in terms of the number of patients with infusion set occlusions. Secondary Objectives: * To assess the safety of SAR341402 and NovoLog® when used in external pumps in terms of unexplained hyperglycemia. * To assess the safety of SAR341402 and NovoLog® when used in external pumps in terms of: * Intervals for infusion set changes. * Number of patients with insulin pump for "non-delivery" alarm. * Patient observation of infusion set occlusion. * Adverse events and serious adverse events. * Number of patients with hypoglycemic events \[according to ADA (American Diabetes Association) Workgroup on hypoglycemia\].

The study duration for each patient will be approximately 10 weeks, including a 2-week screening period, 2 treatment periods of 4 weeks each, and 1-day post-treatment safety follow-up period.
