简要总结
This is a phase Ib placebo-controlled study to assess safety, tolerability, pharmacokinetics and pharmacodynamics of SY-009 after Multiple Ascending Doses in patients with Type 2 Diabetes Mellitus (T2DM).
详细描述
This is a multicenter, randomized, double-blind, placebo-controlled, dose-increasing, multiple oral administration clinical trial. The planned dose escalation levels were 1, 2, 3 and 4 mg daily (6 dose groups).
After the completion of the test and safety evaluation of the initial dose of 1mg daily dose in two groups (0.5mg bid and 1mg QD), the main researchers of the team leader and the sponsor jointly determine whether to enter the 2mg daily dose study.
After the completion of the test and safety evaluation of two groups (1mg bid and 2mg QD) of 2mg daily dose, the main researchers of the group leader and the sponsor jointly determine whether to enter the 4mg daily dose study.
If the test and safety assessment of 4mg daily dose group (2mg bid) are completed and the dose termination standard is not met, the test will be terminated; if the safety assessment during or after the test reaches the dose termination standard, the study of 3mg daily dose group (1.5mg bid) will be carried out, and then the test will be terminated.
