Study Details

Study Description

Brief Summary

The efficacy and safety of Cilostazol and Probucol in combination on patients with diabetic nephropathy is better than the single use.

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed Description

The objectives of this study is:
  1. To evaluate the efficacy of Probucol on deferring nephropathy development of the patients with diabetic nephropathy (including: the change value of urine albumin from the baseline, the rate of the patients with serum creatinine reaching a doubling of the base-line serum creatinine, the rate of the hemodialysis-free survival).

  2. To evaluate the efficacy of Cliostazol and Probucol in combination on deferring nephropathy development of the patients with diabetic nephropathy

  3. To evaluate the efficacy of Cilostazol and Probucol in combination on atherosclerosis related biomarkers change. Atherosclerosis related biomarkers include:(a)Endothelium parameter: ICAM-1, vWF, VCAM-1,and McP-1. (b)Finolysis parameter: TM. (c)Inflammation parameter: Hs-CRP; IL-6. (d)Oxidation parameter: Ox-LDL, 8-OHdG. (e)Lipid parameter: TC, LDL-C, HDL-C, TG.

  4. To evaluate the efficacy of Cilostazol and Probucol in combination on the progress of carotid intima-media thickness (IMT) on patients with diabetic nephropathy.

  5. To evaluate the safety of Cilostazol and Probucol in combination on the patients with diabetic nephropathy.

Outcome Measures

Primary Outcome Measures

  1. nephropathy development [96W]

    After 96-week treatment, compare the efficacy between Probucol group and group control group on deferring nephropathy development of the patients with diabetic nephropathy (including: the change value of urine albumin from the baseline, the rate of the patients with serum creatinine reaching a doubling of the base-line serum creatinine, the rate of the hemodialysis-free survival)

Secondary Outcome Measures

  1. IMT [48 and 96W]

    After 48-week and 96-week treatment, compare the change value of IMT from the baseline among 3 modality groups.

  2. Atherosclerosis related biomarkers [48 and 96W]

    After 12-week, 48-week and 96-week treatment, compare the change value of atherosclerosis related biomarkers from the baseline among 3 modality groups

  3. Nephropathy development [48 and 96W]

    1. After 48-week and 96-week treatment, compare the efficacy among 3 modality groups on deferring nephropathy development of the patients with diabetic nephropathy (including: the change value of urine albumin from the baseline, the rate of the patients with serum creatinine reaching a doubling of the base-line serum creatinine, the rate of the hemodialysis-free survival)

  4. Adverse events [96W]

    Incidence of adverse events, clinically relevant abnormal laboratory results before and after treatment (including hemotology, biochemistry, routine urine analysis and glycosylated hemoglobin), abnormal findings of vital sign, physical examination, and 12-lead ECG results
