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

11 mars 2016 mis à jour par: 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).

La description

Inclusion Criteria:

Study Parts A and B:

Part A:

-Cirrhosis with clinical and/or endoscopic evidence of portal hypertension (e.g. oesophageal varices).

Part B:

  • Cirrhosis with TIPSS in situ and PPG>5mmHg.
  • 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

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Part A: Terlipressin acetate
Patients received terlipressin acetate 2 mg intravenous (IV) bolus injection.
Médicament: Terlipressin acetate
IV bolus injection
Expérimental: 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
Médicament: Serelaxin (RLX030)
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
Expérimental: 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.
Médicament: Serelaxin (RLX030)
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

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Change From Baseline of the Blood Flow for the Total Renal Arteries (Study Part A (Serelaxin Treatment Group Only))
Délai: 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)
Délai: 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
