An Exploratory Haemodynamic Study in Patients With Compensated Cirrhosis and Portal Hypertension

2016年3月11日 更新者:Novartis Pharmaceuticals

An Exploratory Study to Investigate the Haemodynamic Effects of Serelaxin (RLX030) in Patients With Compensated Cirrhosis and Portal Hypertension

The main purpose of this exploratory study was to investigate the effect of serelaxin (RLX030) infusion on the hepatic and renal circulation in patients with compensated cirrhosis and portal hypertension. Measurements were acquired non-invasively using magnetic resonance angiography (MRA) (study part A) and more directly via cannulation of the hepatic portal vein during a routine transjugular intrahepatic portosystemic shunt (TIPSS) check procedure (study part B), to determine the acute haemodynamic response to serelaxin (RLX030).

武器和干预

参与者组/臂
干预/治疗
实验性的:Part A: Terlipressin acetate
Patients received terlipressin acetate 2 mg intravenous (IV) bolus injection.
IV bolus injection
实验性的:Part A: Serelaxin (RLX030)
Randomized patients received an intravenous serelaxin infusion at two different infusion rates: 80 μg/kg/day for 60 min followed by 30 μg/kg/day for at least 60 min.; duration of infusion depends on time required for completion of magnetic resonance angiography (MRA) data acquisition
Part A2: IV infusion for 2-3 hours; duration of infusion depends on time required for completion of MRA data acquisition; Part B: IV infusion for approximately 2 hours
实验性的:Part B Serelaxin (RLX030)
The patients enrolled in this part of the study received an intravenous (iv) serelaxin infusion at two different infusion rates: 80 μg/kg/day for 60 min followed by 30 μg/kg/day for at least 60 min; duration of infusion depends on time required for completion of Portal pressure gradient (PPG) data acquisition.
Part A2: IV infusion for 2-3 hours; duration of infusion depends on time required for completion of MRA data acquisition; Part B: IV infusion for approximately 2 hours

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Change From Baseline of the Blood Flow for the Total Renal Arteries (Study Part A (Serelaxin Treatment Group Only))
大体时间:Baseline, 120 min post serelaxin infusion
The flow is the average flow over the cardiac cycle. Total renal artery flow = left renal artery flow + right renal artery flow. These measurements were collected through magnetic resonance angiography (MRA) scans. Baseline blood flow for total renal artery is measured at pre-dose (Day 1, 0 min post-treatment)
Baseline, 120 min post serelaxin infusion
Change From Baseline of the Portal Pressure Gradient (PPG) (Study Part B)
大体时间:Baseline, 120 min post-infusion start

Direct venous pressure was measured by portal pressure gradient (PPG). PPG = portal vein pressure (PVP) - inferior vena cava pressure (IVCP).

Baseline blood flow for PPG was measured at pre-dose (Day 1, 0 min post-treatment). PVP was measured at 15 min intervals (i.e. prior to and at 15, 30, 45, 60, 75, 90, 105, and 120 min of serelaxin infusion).
