Japanese evaluation between FormuLa of Azelnidipine and amlodipine add on olmesartan to Get antialbuminuric effect study

Basic Information

Recruitment status Complete: follow-up complete
Health condition(s) or Problem(s) studiedHypertensive patients with albuminuria and diabetes (diabetic nephropathy)
Date of first enrollment2009/05/01
Target sample size250
Countries of recruitmentJapan
Study typeInterventional
Intervention(s)Azelnidipine (8 to 16 mg/day) is added in patients with olmesartan and target blood pressure (BP) is under 130/80 mmHg, Amlodipine (2.5 to 5 mg/day) is added in patients with olmesartan and target BP is under 130/80 mmHg


Primary OutcomeChanges in urinary albumin/creatinine (Cr) ratio in spot urine from pretreatment period (average of 2 measured value) to 12 months of treatment
Secondary Outcome1. Percent changes in urinary albumin/Cr ratio from pretreatment period to each period of treatment. Urinary protein/Cr ratio is analyzed similarly to urinary albumin/Cr ratio. 2. Urinary liver-type free fatty acid-binding protein (L-FABP) 3. Urinary 8-hydroxydeoxyguanosine (8-OHdG) 4. Office blood pressure (BP) in outpatient clinic 5. Pulse rate 6. Serum Cr or estimated glomerular filtration rate (eGFR) calculated using the modified MDRD formula in the Japanese Society of Nephrology: eGFR (ml/min/1.73 m2) = 194 x age -0.287 x serum creatinine – 1.094 (multiply by 0.739 in female) 7. Cerebro-cardio-vascular events: cerebro-cardio-vascular mortality (fatal myocardial infarction, fatal heart failure, sudden death, fatal stroke, other cardiovascular death) and hospitalization due to cerebro-cardio-vascular disease (nonfatal myocardial infarction, angina, heart failure, cerebral bleeding, cerebral infarction, transient cerebral ischemic attack)

Key inclusion & exclusion criteria

Past history of severe side effect of CCB, ARB, or ACE inhibitor 5. Cerebrovascular disease occurs within 6 months 6. Sever heart failure (NYHA class >= III), severe arrhythmia (frequent ventricular or atrial extrasystole, prolonged ventricular tachycardia, atrial tachyrhythmia with severe tachycardia, atrial fibrillation or flutter with severe tachycardia, sick sinus syndrome with severe bradycardia, atrio-ventricular block with severe bradycardia), myocardial infarction or percutaneous transluminal coronary angioplasty within 6 months 7. Type 1 diabetes and type 2 diabetes required hospitalization due to high hemoglobin A1c (>= 9.0), extremely high blood glucose, or diabetic ketoacidosis 8. AST or ALT is more than 5 times higher upper limits 9. Malignancy 10. Pregnant, possible to be pregnant, or willing to be pregnant 11. Patients who are inadequate by determination of physician in charge
