Objectives

Narrative objectives1

Protocol A: Prevention of nephropathy progression in the integrated therapy for diabetic patients with overt nephropathy (urinary albumin/creatinine ratio>=300mg/gCr, and serum creatinine level<1.2mg/dL for male; serum creatinine level<1.0mg/dL for female) randomized to the integrated therapy or the conventional therapy is examined by assessing the excretion of urinary protein as a primary outcome.Protocol B: Prevention of nephropathy progression in the integrated therapy for diabetic patients with overt nephropathy (urinary albumin/creatinine ratio >= 300mg/gCr, and 1.2mg/dL <= serum creatinine level <= 2.5mg/dL for male; 1.0mg/dL <= serum creatinine level <= 2.5mg/dL for female) randomized to the integrated therapy or the conventional therapy is examined by assessing the doubling of serum creatinine level, introduction of dialysis therapy or renal transplant, and death as primary outcomes.

Key inclusion criteria

Sujects are eligible if all of the following criteria are satisfied:1) Patients with type 2 diabetes mellitus (according to the diagnostic criteria of Japan Diabetes Society, 1999)2) Patients who show urinary albumin/creatinine ratio >= 300mg/gCr (first urine in early-morning) twice in succession through the observation period.3) Patients with serum creatinine level <2.5mg/dL through the observation period.4) Patients whose consent is obtained at age >20 years or <70 years.When the criteria 2) and 3) are not fulfilled, eligibility may be confirmed by obtaining additional samples. However, the prolongation of the observation period is limited up to 3 months.

Key exclusion criteria

Patients who fall into the following categories are not eligible:1) Patients with type 1 diabetes mellitus2) Patients with hereditary diabetes mellitus or secondary diabetes mellitus.3) Patients with non-diabetic nephropathy, e.g., glomerular nephritis, lupus nephritis.4) Patients with familial hypercholesterolemia.5) Patients with secondary hypertension.6) Patients with unstable angina pectoris, or patients who have developed myocardial infarction or cerebral hemorrhage within 6 months prior to the observation period.7) Patients with any life-threatening disease which will be the cause of death within five years such as malignant tumor.8) Patients with a history of angio edema.9) Patients under LDL-apheresis by a adsorber with dextran sulphate cellose.10) Patients with biliary obstruction or severe hepatopathy.11) Patients considered as having hypergasia of hepatic metabolism such as acute hepatitis, acute exacerbation of chronic hepatitis, cirrhosis, hepatic cancer, or jaundice.12) Patients with a history of hypersensitivity against ACE inhibitors, ARBs, or HMG-CoA reductase inhibitors.13) 0patiens, and patients who want to become pregnant during the study period.14) Other patients judged as being inappropriate for the subjects of the study by investigators.
