The purpose of this trial is to investigate safety, tolerability, pharmacodynamics (PD), and pharmacokinetics (PK) after intravenous (IV) administration of FE 204205 in patients with cirrhotic portal hypertension.
The trial aimed to evaluate the safety, tolerability, PK and PD of IV FE 204205 in cirrhotic patients with portal hypertension and was planned in 2 parts: Part 1 of the trial was open-label where six subjects were planned to receive three ascending doses of FE 204205, given as infusion over 2 hours on three consecutive days. Part 2 was planned as a randomised, placebo-controlled, double-blind investigation evaluating the effects of a single dose of FE 204205 on portal haemodynamics in 20 subjects who would have received either the maximum tolerated dose (as defined in Part 1) of FE 204205 (n=16) or placebo (n=4).

In Part 1 of the trial, each subject will receive increasing IV doses of FE 204205, given once daily as 2 hour infusion, on three consecutive days. In Part 2 of the trial, each subject will receive a 2 hour IV infusion of the maximum tolerated dose of FE 204205 as defined in Part 1 of the trial.
In Part 2 of the trial, each subject will receive a 2 hour IV infusion of placebo.

Change in Hepatic Venous Pressure Gradient (HVPG)
The trial was terminated early due to low recruitment. Only four subjects were enrolled into the open-label, exploratory Part 1 of the trial, and only three of these four subjects (all receiving different dosing regimens) completed the trial and the HVPG assessments prior to the early termination decision. No subjects were enrolled into the randomized, double-blind, placebo-controlled Part 2 of the trial. As only Part 2 of the trial would have been appropriately powered, and the three subjects with HVPG assessments from Part 1 all received different dosing regimens, no meaningful statistical analysis could be conducted.
Time frame: From baseline (pre-dose) to 2 hours after start of infusion
Type, Frequency and Intensity of Adverse Events (AEs)
The trial was terminated early due to low recruitment. Only four subjects (all received different dosing regimens) were enrolled into open-label, exploratory Part 1 of the trial, prior to the early termination. No subjects were enrolled in the randomized, double-blind, placebo-controlled Part 2 of the trial. Thus no meaningful statistical analysis could be conducted. Due to the low number of subjects and individual dosing regimens, AEs were pooled for all dose levels.
Time frame: Up to Day 14
Change in Systolic and Diastolic Blood Pressure
The trial was terminated early due to low recruitment. Only four subjects (all received different dosing regimens) were enrolled into open-label, exploratory Part 1 of the trial, prior to the early termination. No subjects were enrolled in the randomized, double-blind, placebo-controlled Part 2 of the trial. Thus no meaningful statistical analysis could be conducted.
Time frame: From baseline (pre-dose) up to Day 14
Change in Plasma Lactate Levels
The trial was terminated early due to low recruitment. Only four subjects (all received different dosing regimens) were enrolled into open-label, exploratory Part 1 of the trial, prior to the early termination. No subjects were enrolled in the randomized, double-blind, placebo-controlled Part 2 of the trial. Thus no meaningful statistical analysis could be conducted.

Pharmacokinetics: Maximum Concentration Observed (Cmax)
The trial was terminated early due to low recruitment. Only four subjects (all received different dosing regimens) were enrolled into open-label, exploratory Part 1 of the trial, prior to the early termination. No subjets were enrolled in the randomized, double-blind, placebo-controlled Part 2 of the trial. Thus no meaningful statistical analysis could be conducted.
Time frame: Pre-dose, 0.5, 1, 2, 3, and 4 hours after start of infusion
Pharmacokinetics: Area Under the Concentration-time Curve to Infinity (AUC)
The trial was terminated early due to low recruitment. Only four subjects were enrolled (all received different dosing regimens) into open-label, exploratory Part 1 of the trial, prior to the early termination. No subjects were enrolled in the randomized, double-blind, placebo-controlled Part 2 of the trial. Thus no meaningful statistical analysis could be conducted.
Time frame: Pre-dose, 0.5, 1, 2, 3, and 4 hours after start of infusion
Pharmacokinetics: Total Systemic Clearance (CL)
The trial was terminated early due to low recruitment. Only four subjects (all received different dosing regimens) were enrolled into open-label, exploratory Part 1 of the trial, prior to the early termination. No subjects were enrolled in the randomized, double-blind, placebo-controlled Part 2 of the trial. Thus no meaningful statistical analysis could be conducted.
Time frame: Pre-dose, 0.5, 1, 2, 3, and 4 hours after start of infusion
Pharmacokinetics: Elimination Half-life (t1/2)
The trial was terminated early due to low recruitment. Only four subjects were enrolled (all received different dosing regimens) into open-label, exploratory Part 1 of the trial, prior to the early termination. No subjects were enrolled in the randomized, double-blind, placebo-controlled Part 2 of the trial. Thus no meaningful statistical analysis could be conducted.
Time frame: Pre-dose, 0.5, 1, 2, 3, and 4 hours after start of infusion
Pharmacokinetics: Volume of Distribution Associated With the Terminal Phase (Vz)
The trial was terminated early due to low recruitment. Only four subjects were enrolled (all received different dosing regimens) into open-label, exploratory Part 1 of the trial, prior to the early termination.

Change in Electrocardiogram (ECG) Parameters
The trial was terminated early due to low recruitment. Only four subjects were enrolled (all received different dosing regimens) into open-label, exploratory Part 1 of the trial, prior to the early termination.
