Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

1. To evaluate the efficacy of Cilostazol and Probucol alone and in combination on atherosclerosis related biomarker
2. To evaluate the safety of Cilostazol and Probucol alone and in combination on atherosclerosis related biomarker

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Efficacy evaluation:

Primary efficacy index:

After 12 weeks of treatment, the change of arteriosclerosis related biomarker in 4 modality groups, comparing with the base line information

Secondary efficacy index:

After 8 weeks of treatment, the change of arteriosclerosis related biomarker in 4 modality groups, comparing with the base line information

Safety evaluation:

1. Adverse Event
2. Vital Sign and Physical Examination
3. 12-lead ECG
4. Laboratory Tests (including blood routine examination, routine urine analysis, blood biochemistry examination, glycosylated hemoglobin)
