Long-Term Renoprotection of Optimal Antiproteinuric Doses of Benazepril and Losartan in Chronic Renal Insufficiency

June 16, 2006 updated by: Southern Medical University, China
The primary goal of the trial was to evaluate whether the optimal antiproteinuric doses of benazepril (an ACE inhibitor) or losartan (an ARB), as compared with their conventional doses, can safely improve the long-term renal outcome in nondiabetic patients with proteinuria and chronic renal insufficiency. The second aim was to compare the long-term renal protection between benazepril and losartan at similar clinical setting.

Exclusion Criteria:

  1. Immediate need for dialysis
  2. Treatment with corticosteroids, non steroidal anti-inflammatory drugs, or immunosuppressive drugs
  3. Hyper-or hypokalemia (serum potassium concentration 5.6 mmol per liter or more，or 3.5 mmol per liter or less)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
The primary efficacy measure was the time to the first event of the composite endpoint of a doubling of the serum creatinine concentration, ESRD or death.

Secondary Outcome Measures

Outcome Measure
Secondary endpoints included changes in urinary protein excretion rate and the progression of renal disease assessed by creatinine clearance and glomerular filtration rate as calculated by Modification of Diet in Renal Disease equation-4.
