What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean change in Hepatic Vein Pressure Gradient (HVPG) from Baseline to Day 14
Time Frame: 14 Days
|
Baseline HVPG is defined as the HVPG assessment performed prior to the first study drug administration.
Day 14 HVPG is defined as the HVPG assessment prior to the last dose of study drug.
The mean change in HVPG will be calculated as the difference between the HVPG assessment performed at Day 14 and the HVPG assessment performed at baseline
|
14 Days
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in 24-hour Urinary Sodium Volume (UNaV)
Time Frame: 48 hours
|
The change in 24-hour Urinary Sodium Volume (UNaV) will be calculated as the difference in 24-hour UNaV at Baseline and the 24-hour UNaV at Day 1 (after the first study drug administration). Urinary sodium volume collected in the 24 hours of baseline will be compared to the Urinary sodium volume collected in the 24 hours after the first dose of the drug. Collection of urine will be ongoing for 48 hours in total. |
48 hours
|
Change in weight
Time Frame: 28 days
|
The change in weight will be calculated as the difference in weight at baseline and weight recorded throughout the study
|
28 days
|
Change in abdominal girth
Time Frame: 28 days
|
The change in abdominal girth will be calculated as the difference in abdominal girth at baseline and abdominal girth recorded throughout the study
|
28 days
|
Change in Model of End-Stage Liver Disease (MELD) score
Time Frame: 28 days
|
The change in MELD score will be calculated as the difference in MELD score at baseline and the MELD scores recorded throughout the study. The MELD score is calculated according to the following formula: MELD = 3.78×ln[serum bilirubin (mg/dL)] + 11.2×ln[INR] + 9.57×ln[serum creatinine (mg/dL)] + 6.43 The MELD score provides an indication of the anticipated mortality observed in previous studies when subjects were followed for 3-months, according to the following ranges: 71.3% mortality if score is 40 points or more 52.6% mortality if score between 30-39 points 19.6% mortality if score between 20-29 points 6.0% mortality if score between 10-19 points 1.9% mortality if score 9 points or less The MELD score will be calculated at each visit during a 28 day period. |
28 days
|
Change in Child-Pugh score
Time Frame: 28 days
|
The change in Child-Pugh score will be calculated as the difference in Child-Pugh score at baseline and the Child-Pugh scores recorded throughout the study The Child-Pugh score provides information on the prognosis of a patient based on 5 clinical parameters which are individually graded. These parameters include laboratory values and other clinical information from the patient, such as the presence of ascites or hepatic encephalopathy. A lower score signifies a better chance and a higher score indicates a worse chance of survival at one year. Once the score is calculated it is further subclassified into three stages, depending on the score: Child A - the score is between 5 and 6. The survival rate is 100% Child B - the score is between 7 and 9. The survival rate is 80% Child C - the score is between 10 and 15. The survival rate is 45% |

|
Change in Pulmonary Arterial Pressure
Time Frame: 14 days
|
