About this study

Pilot study examining changes in liver stiffness measured by ultrasound before and after TIPS creation

Read the detailed description

Single arm pilot study of adults ≥18yo investigating changes in liver stiffness as measured by ultrasound acoustic radiation force impulse (ARFI) before and after creation of TIPS. Duration of participation is 30 days from TIPS creation. TIPS creation with Viatorr stent graft will be in accordance with its FDA-approved indication for symptomatic portal hypertension and per the manufacturer's instructions for use. Liver stiffness will be measured on pre-TIPS and post-TIPS ultrasounds using Phillips Epiq Ultrasound systems equipped with ElastPQ ultrasound shear wave elastography. Both ultrasounds will be performed at times which are standard of care before and after TIPS creation. Primary objectives include liver stiffness as measured by ultrasound acoustic radiation force impulse (ARFI) before and after creation of TIPS. Secondary objectives include change in portosystemic gradient, clinical success as measured by difference in frequency of repeat paracentesis post-TIPS or freedom from recurrence of variceal bleeding and rate of hepatic encephalopathy. Exploratory objectives include serum biomarkers of liver stiffness.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • UltrasoundDiagnostic test

    Hepatic ultrasound using gray scale, color Doppler, and spectral Doppler imaging to evaluate hepatic vein and portal vein patency, direction and velocity of flow respectively. ARFI will be performed in the right hepatic lobe. Three measurements of stiffness (m/s) will be performed and the mean value recorded.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Decrease in Liver Stiffness

    The primary study endpoint will be decrease in liver stiffness following TIPS creation as measured by ARFI using mean propagation velocity values in meters per second. Mean normal values and mean values indicating severe fibrosis range about 0.8-1.7 m/s and about 1-3.4 m/s respectively. We hypothesize TIPS creation will reduce the liver stiffness by > 50%. Change in liver stiffness will be correlated to change in PSG.

    Measured: Pre-TIPS and 30 days Post-TIPS creation

Secondary outcomes (4)
  1. PSG (mm hg) and ARFI (m/s) Correlation

    Baseline PSG (mm Hg) correlation to baseline liver stiffness by ultrasound ARFI (m/s)

    Measured: Pre-TIPS and 30 days Post-TIPS creation

  2. Frequency of Paracentesis and Recurrence of Variceal Bleeding

    Difference in frequency of paracentesis and freedom from recurrence of variceal bleeding at 30 days and 12 months post-TIPS placement

    Measured: 30 days Post-TIPS and 12 months Post-TIPS creation

  3. Hyaluronic Acid and ARFI Correlation

    Correlation of hyaluronic acid, a serum marker of liver stiffness, with baseline ARFI measurements, non-invasive radiographic assessment of liver stiffness

    Measured: Pre-TIPS and 30 days Post-TIPS creation

  4. Tissue Inhibitor of Metalloproteinase-1 and ARFI Correlation

    Correlation of tissue inhibitor of metalloproteinase-1, a serum marker of liver stiffness, with baseline ARFI measurements, non-invasive radiographic assessment of liver stiffness

    Measured: Pre-TIPS and 30 days Post-TIPS creation

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasound in people with Portal Hypertension and Liver Fibroses, run by University of Pennsylvania at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 1 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Oct 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Decrease in Liver Stiffness (time frame: Pre-TIPS and 30 days Post-TIPS creation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2019.
