Mylan Insulin Aspart Study

This is a multicenter, open-label, randomized, parallel-group phase 3 study in subjects with T1DM comparing the safety and efficacy of MYL-1601D with NovoLog®. After up to 3-week screening period, all subjects will be titrated on NovoLog® during a 4-week run-in period, and will be shifted from their current basal insulin to study insulin Lantus®. After run-in period, subjects will be randomized; one group will receive MYL-1601D, while the other group will receive NovoLog® for 24 weeks. A follow-up visit, via telephone call, will be scheduled 4 weeks after last dose of MYL-1601D.
