  Purpose

Activation of renin-angiotensin plays a crucial role diabetic nephropathy. Angiotensin converting enzyme inhibitor (ACEI) and Angiotensin I receptor blocker (ARB) has been shown renoprotection whether it was used alone or in combination. Aliskiren is a direct renin inhibitor (DRI) that has shown renal benefits and safety when combined with ARB. However, to date, the safety of add on aliskiren to the combination treatment of ACEI and ARB in diabetic nephropathy patients remains to elucidate.

Primary Outcome Measures:
  • Assess short-term safety of the combination of aliskiren 300 mg/valsartan 160 mg /enalapril 20 mg in patients with diabetic nephropathy [ Time Frame: 12 wk after randomization ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Reduction of systolic blood pressure [ Time Frame: 12 wk after randomization ] [ Designated as safety issue: No ]
  • Reduction of proteinuria [ Time Frame: 12 wk after randomization ] [ Designated as safety issue: No ]
  • Change in GFR/mo [ Time Frame: 12 wk after randomization ] [ Designated as safety issue: Yes ]
  • Change of Serum prorenin level compare to baseline [ Time Frame: 12 wk after randomization ] [ Designated as safety issue: No ]
  • Change of Urinary TGFb1 compare to baseline [ Time Frame: 12 wk after randomization ] [ Designated as safety issue: No ]
