The EUS ShearWave Elastography Liver Fibrosis Study

September 8, 2021 updated by: Olympus Corporation of the Americas

Pilot Study Evaluating Endoscopic Ultrasound With ShearWave Elastography for Diagnosis and Staging of Liver Fibrosis

The study objective is to demonstrate the clinical performance of ShearWave Elastography (SWE) in Endoscopic Ultrasound (EUS) when compared to FibroScan for evaluation of liver fibrosis.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study has been designed as prospective, single center, single arm, consecutive, blinded, pilot study conducted in a post-market setting using commercially available devices to evaluate the effectiveness of Endoscopic Ultrasound with ShearWave Elastography to estimate hepatic fibrosis in patients with chronic liver disease. It is anticipated that the data from this study will support the need for additional clinical trials. All consenting, eligible patients reporting for an ultrasound and/or liver biopsy for evaluation of fibrosis meeting the inclusion criteria will be consecutively enrolled into the study and assigned a unique study identification number. A total of 52 subjects will be enrolled and treated at a single study site in the US. Enrollment is expected to be completed within 6 months. Each subject will undergo both procedures (FibroScan and EUS with SW Elastography), End of study will be reached after pathology results have been obtained (within a week of the initial procedure).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 96 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Treatment Arm
Consecutive, eligible patients reporting for an ultrasound and liver biopsy for evaluation of fibrosis will be enrolled. Each subject will undergo both procedures (FibroScan and EUS with SW Elastography).
Device: ShearWave Elastography (SWE) in Endoscopic Ultrasound (EUS)
ShearWave Measurement is a software option available on the ARIETTA 850 that uses transient pulses to generate shear waves in the body. The tissue's elasticity is directly deduced by measuring the speed of wave propagation.
Device: FibroScan
manufactured by Echosens
Device: ALOKA ARIETTA 850 -
manufactured by Hitachi Healthcare - included on the system is the ShearWave measurement software

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Analyze the correlation between SWE of liver and FibroScan of liver with histologic fibrosis stage using Spearman Correlation Coefficient.
Time Frame: 6 months
Use ANOVA with Tukey Range test to evaluate the level of significance of difference in SWE results across fibrosis stages.
6 months
Analyze the correlation between SWE of liver and FibroScan of liver with histologic fibrosis stage using Spearman Correlation Coefficient.
Time Frame: 6 months
Construct receiver operating characteristic curves (ROC) to determine which liver section (left or right) had best accuracy of prediction of fibrosis stage and compared overall accuracy between SWE and TE.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
