ALTA TIPS: A 5-year Longitudinal Observational Study of Patients Undergoing TIPS Placement
Rochester, MN
ALTA is a multicenter consortium focused on the management of portal hypertension. ALTA TIPS is a longitudinal observational study of patients who are undergoing transjugular intrahepatic portosystemic shunt (TIPS) placement. ALTA will create a database that will provide clinical parameters and outcomes of patients undergoing TIPS as part of their standard of care in hopes of answering key clinical questions.

A Biorepository to Study Portopulmonary Hypertension
Rochester, MN
We propose to develop a biorepository of plasma samples from patients with suspected and confirmed portopulmonary hypertension to improve our understanding of this disease and its response to pulmonary arterial hypertension targeted therapy and liver transplantation.

A Multicenter Open Label Trial Using Ambrisentan in Patients with Porto-pulmonary Hypertension
Jacksonville, FL
This is an Open Label, Multicenter, pilot clinical trial to assess the efficacy and safety of an oral selective Endothelin Receptor Antagonist (ambrisentan) in patients with portopulmonary hypertension.
Preliminary evidence suggests that ambrisentan is safe and effective in patients with portopulmonary hypertension. The goal of therapy for these patients is to improve symptoms of dyspnea and to improve pulmonary hemodynamics to a mean pulmonary artery pressure <35 mm Hg in order to make patients eligible for liver transplantation. Therefore, the primary endpoints for this study will include 6 minute walk distance (6MWD) and pulmonary vascular resistance (PVR).

Emricasan, an Oral Caspase Inhibitor, in Subjects With Non-Alcoholic Steatohepatitis (NASH) Cirrhosis and Severe Portal Hypertension
Rochester, MN
This is a multicenter, randomized, double-blind, placebo-controlled trial involving subjects with NASH cirrhosis and severe portal hypertension (defined as HVPG ≥12 mmHg as determined by the central reader assigned to this study). Upon successful screening, subjects will be randomized to receive either emricasan 50 mg BID, 25 mg BID, or 5 mg BID or matching placebo BID.

A Study to Evaluate Smartphone-based Digital Phenotyping for Relapse Prediction in Alcohol-associated Liver Disease
Rochester, MN
The primary aim of this study is to define a comprehensive digital phenotype that predicts risk for near-future relapse or relapse in alcohol use in patients with alcohol-associated liver disease.
The secondary aim of this study is to assess the relationship between this digital phenotype and markers of disease severity outcome, including MELD score and readmission rates.
