21. Dezember 2012 aktualisiert von: Novartis Pharmaceuticals

A Single-blind, Double Dummy, Randomized, Multi-dose, Two Sequence, Crossover, Study to Investigate the Effects of Renin Inhibitor (Aliskiren 300 mg) on Albuminuria in Non-diabetic Nephropathy Patients Treated With Ramipril 10 mg and Volume Intervention (ARIA)

The study is designed to primarily assess the effect of aliskiren on albuminuria in patients with non-diabetic nephropathy when treated with ramipril and volume intervention.

Effect of Aliskiren on Albuminuria as Measured by Urinary Albumin Excretion Rate (UAER)
Zeitfenster: 26 weeks
Two 24-hour collections of urine were to be made at each study visit. The arithmetic mean of the two collections were planned to be used in the calculation of summary statistics and the statistical analyses.

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Mean Sitting Systolic Blood Pressure (msSBP)
Zeitfenster: 26 weeks
At study entry, blood pressure (BP) was measured in both arms. If there was a clinically relevant difference in readings between arms (≥ 10 mmHg in systolic BP and/or ≥ 5 mmHg in diastolic BP), the arm with higher BP reading was used. If there was no clinically significant difference between arms, the non-dominant arm was used through out study. Systolic blood pressure were assessed after the patient rested quietly in the sitting position for at least 3 minutes. For each sitting assessment, blood pressure was assessed at least 3 times. From these assessments, msSBP was calculated. All BP measurements were to be performed on the same arm.
26 weeks
Mean Sitting Diastolic Blood Pressure (msDBP)
Zeitfenster: 26 weeks
At study entry, blood pressure (BP) was measured in both arms. If there was a clinically relevant difference in readings between arms (≥ 10 mmHg in systolic BP and/or ≥ 5 mmHg in diastolic BP), the arm with higher BP reading was used. If there was no clinically significant difference between arms, the non-dominant arm was used through out study. Diastolic blood pressure were assessed after the patient rested quietly in the sitting position for at least 3 minutes. For each sitting assessment, blood pressure was assessed at least 3 times. From these assessments, msDBP was calculated. All BP measurements were to be performed on the same arm.
26 weeks
Mean Glomerular Filtration Rate (GFR) as Measurement of Renal Function
Zeitfenster: 26 weeks
All patients had to visit the main center for renal function measurements. The measurements were performed using the constant infusion method with I-iothalamate (IOT) and I-hippuran. GFR was calculated as the urinary clearance of IOT.
26 weeks
Mean Effective Renal Plasma Flow (ERPF) as One of Hemodynamic Assessments
Zeitfenster: 26 weeks
26 weeks
Percentage of Renal Filtration Fraction (RFF) as One of Hemodynamic Assessments
Zeitfenster: 26 weeks
26 weeks
Mean Extracellular Volume (ECV) as One of Hemodynamic Assessments
Zeitfenster: 26 weeks
26 weeks
Plasma Rennin Activity (PRA)
Zeitfenster: Baseline to week 26
Blood biomarkers were obtained from blood samples in all patients at the time points such as baseline, week 6, week 12, week 18 and week 26. Plasma PRA is a direct measure of the formation of Ang I in the plasma.
Baseline to week 26
Plasma Rennin Concentration (PRC)
Zeitfenster: Baseline to week 26
Blood biomarkers were obtained from blood samples in all patients at the time points such as baseline, week 6, week 12, week 18 and week 26. PRC measures the concentration of immunoactive renin in the plasma.
