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

March 11, 2016 updated by: 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).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline of the Blood Flow for the Total Renal Arteries (Study Part A (Serelaxin Treatment Group Only))
Time Frame: 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)
Time Frame: 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).
Baseline, 120 min post-infusion start

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
