Further study details as provided by University of Florida:

Primary Outcome Measures:
  • Number of patients with worsening ascites [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    Increase in # of therapeutic paracentesis (removal of > 2 litres of ascites fluid) or weight increase of > 2kg from baseline


Secondary Outcome Measures:
  • Number of patients with reduction of ascites [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Reduction of weight by at least 2 kg or reduction in frequency/amount of paracentesis compared to baseline without any increase in diuretic treatment or therapeutic paracentesis.

  • Number of Patients with Potentially Clinically Significant Abnormal Labs [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
    Number of Patients with Potentially Clinically Significant Abnormal Labs as defined in the protocol
