설명
Inclusion Criteria:
Study Parts A and B:
-Cirrhosis of alcohol aetiology according to physician's assessment prior to screening.

- Fully functioning TIPSS without variceal filling as confirmed by portography.
Exclusion Criteria:
Study Parts A and B:
- Use of any drug to treat portal hypertension (e.g. vasodilators such as non-selective beta blockers or nitrates) within 1 month prior to screening.
- Decompensated cirrhosis (Child-Pugh score >9 points, and/or ascites requiring diuretics, and/or hepatic encephalopathy) at visit 1.
- Presence of any non-controlled and clinically significant disease that could affect the study outcome or that would place the patient at undue risk.
Part A:
- BMI (weight[kg] / height[m^2]) > 40 kg/m^2.
- Any contraindication to having an MRI scan
Part B:
-Contraindication to catheterization

실험적: Part A: Terlipressin acetate
Patients received terlipressin acetate 2 mg intravenous (IV) bolus injection.
|
IV bolus injection
|
|
실험적: 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
|
|
실험적: 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.

|
Change From Baseline of the Blood Flow for the Total Renal Arteries (Study Part A (Serelaxin Treatment Group Only))
기간: 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)
기간: 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). |

Change From Baseline of the Blood Flow for the Hepatic Artery (Study Part A (Serelaxin Treatment Group Only))
기간: Baseline, 120 min post-infusion
|
A non-contrast magnetic resonance angiography (MRA) sequence was performed to acquire phase contrast blood flow measurements from vessels of interest such as hepatic artery. The flow is the average flow over the cardiac cycle. Baseline blood flow measurements are measured at pre-dose (Day 1, 0 min post-treatment). |
