Study Details

Study Description

Brief Summary

The purpose of this study is to demonstrate that TIPS with the GORE® VIATORR® TIPS Endoprosthesis improves transplant-free survival compared to LVP alone in patients who have cirrhosis of the liver with portal hypertension and difficult to treat ascites.

Condition or Disease Intervention/Treatment Phase
  • Device: TIPS procedure with the GORE® VIATORR® TIPS Endoprosthesis
  • Procedure: LVP
  • Device: TIPS procedure with the GORE® VIATORR® TIPS Endoprosthesis for subjects who failed LVP and crossed over to TIPS per protocol

Active Comparator: LVP

Large Volume Paracentesis *A subject may be crossed-over from large volume paracentesis to TIPS with GORE® VIATORR® TIPS Endoprosthesis if the subject has completed their six month study visit and has met the criteria for cross-over (LVP failure).

Outcome Measures

Primary Outcome Measures

  1. Transplant-free Survival [Through 24 months]

    Time from randomization to death from any cause prior to transplant. Subjects who undergo liver transplant will be censored at the time of transplant. Subjects without an event will be censored at the date of last follow-up. Note: The outcome entered below is the number of participants who were either alive or had a liver transplant at time of study termination.

Secondary Outcome Measures

  1. Overall Survival [Through 24 months]

    Time from randomization to death from any cause. Subjects without an event will be censored at the date of last follow-up. > *Note: Outcome measure entered below is number of subjects alive at time of study termination.

  2. Time to Transplant [Through 24 months]

    Time from randomization to transplant. Subjects without an event will be censored at the date of last follow-up or date of death without transplant. *Note: Outcome measure entered is number of subjects who received a liver transplant at time of study termination.

  3. Frequency of Paracentesis [Through 24 months]

    Number of paracentesis post randomization

  4. Frequency of Hepatic Encephalopathy [Through 24 months]

    Number of episodes of West Haven grade 2 or greater

  5. Procedural Success [Time of TIPS Procedure (within 2 weeks of enrollment for TIPS arm, at least 6 months after enrollment for Control arm crossover participants)]

    Successful creation of a VIATORR(R) device lined portosystemic shunt spanning a hepatic vein and intrahepatic branch of the portal vein *Note: Control (LVP) arm includes only subjects who crossed over to TIPS

  6. Liver Disease Complications (Adverse Events) [Through 24 months]

    Overall frequency and component frequencies. Complications will include hepatic encephalopathy, hepatic hydrothorax, hepatoma, hepatorenal syndrome (Type 1 or Type 2), hyponatremia (<130mEq / L), spontaneous bacterial peritonitis, and variceal bleeding.
