A Phase III Study of Insulin Aspart Injection to Evaluate the Efficacy and Safety

A Multi-center, Randomized, Open-label, Parallel-group, Phase Ⅲ Study to Evaluate the Efficacy and Safety of Insulin Aspart Injection in Patients With Diabetes Mellitus Compared to NovoRapid®

This is a multicenter, randomized, open, parallel group, active-controlled study. The study period is 25 to 26 weeks, including screening period of 1-2 weeks and treatment period of 24 weeks.

After the screening visit, all patients who met all inclusion criteria and do not meet any of the exclusion criteria were randomized into the experimental group or the controlled group. The subjects in the experimental arm will receive insulin aspart injection combined with basal insulin (Lantus ®), and the subjects in the controlled arm will receive NovoRapid ® (active control) combined with basal insulin (Lantus ®). The experimental drug or the controlled drug will be administered subcutaneously prior to three meals (or can be administered immediately after meal if necessary), and the basal insulin (Lantus ®) will be administered at bedtime. The treatment period is 24 weeks, during which the subjects will be followed up at the clincic cetres at 1, 2, 4, 8, 12, 18, 24 weeks of treatment. At the end of 24-week treatment, if the adverse events continue, the subjects will be followed until recovery or stabilization of the AEs.
