Trial Outcomes & Findings for An Exploratory Haemodynamic Study in Patients With Compensated Cirrhosis and Portal Hypertension (NCT NCT01640964)

NCT ID: NCT01640964

Last Updated: 2016-03-15

Results Overview

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)

Measure
Part A: Terlipressin Acetate
Patients received terlipressin acetate 2 mg intravenous (IV) bolus injection.
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 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 the Portal pressure gradient (PPG) data acquisition.

PRIMARY outcome

Timeframe: Baseline, 120 min post-infusion start

Population: For Part B of the study, full analysis set included all patients who received any amount of study treatment during the treatment period and had at least one post-baseline assessment during that period.Only patients with a value at both baseline and this time point are included.

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).
