About this study

Official title: Clinical Study of the BreathID® LF System to Train the Algorithm for the ¹³C-Methacetin Breath Test (MBT) in Assessment of Portal Hypertension in Patients With Compensated Liver Cirrhosis

This study will be used to train an algorithm using Methacetin breath test (MBT) measures and to select a cut-off to determine presence or absence of Clinically Significant Portal Hypertension (CSPH) as defined by Hepatic Venous Gradient Pressure (HVPG) ≥ 10mmHg,

Read the detailed description

The portal pressure leaving the liver is measured by using a balloon catheter before and after a wedge. The difference of the pressure between the wedge and the free is the hepatic venous pressure gradient. Methacetin breath test is hypothesized to also identify CSPH and the agreement to the reference standard (HVPG) will be assessed in this study.

What is being measured

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

  1. CSPH (Clinically Significant Portal Hypertension)

    Clinically significant portal hypertension is defined as Hepatic Venous Pressure Gradient (HVPG)>=10mmHg, whereby the portal pressure leaving the liver is measured by using a balloon catheter before and after a wedge. The difference of the pressure between the wedge and the free is the hepatic venous pressure gradient. Methacetin breath test is hypothesized to also identify CSPH and the agreement to the reference standard (HVPG) will be assessed in this study.

    Measured: 1 hour

Secondary outcomes (1)
  1. Hepatic Venous Pressure Gradient (HVPG)>=12; Severe Portal Hypertension (SPH)

    Hepatic Venous Pressure Gradient greater than 12 (SPH) is an indicator of bleeding varices. whereby the portal pressure leaving the liver is measured by using a balloon catheter before and after a wedge. The difference of the pressure between the wedge and the free is the hepatic venous pressure gradient. Methacetin breath test is hypothesized to also identify SPH and the agreement to the reference standard (HVPG) will be assessed in this study.

    Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

A study testing Methacetin Breath Test in people with Patients With Compensated Liver Cirrhosis, run by Meridian Bioscience, Inc. at 8 sites in 4 countries.

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 6 inclusion and 21 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: finished, as of the sponsor's last update on 20 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States, France, Spain, Switzerland. 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 19 Sep 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?

CSPH (Clinically Significant Portal Hypertension) (time frame: 1 hour). 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 20 Dec 2022.
