Clinical Trial Summary

The primary objective of this study is to evaluate to provide evidence to establish tightly defined cut-offs to identify patients for NASH clinical trial inclusion using cT1 and/or PDFF. The study will be divided into 2 sub groups comprising of cases and controls.

Description:

This is a prospective, case-control, study designed to measure the mean difference in cT1 and PDFF in patients who have undergone liver biopsy and have confirmed NASH and fibrosis or 'cases' (N=40) and N=20 patients with neither significant NASH nor significant fibrosis 'controls'. Confirmed cases will be patients who have met the criteria for active NASH with fibrosis according to the NAS CRN scoring system (NAS≥4 & F2-3), 'controls' will be those who did not meet NASH diagnostic criteria and have evidence of fibrosis of ≤2. In addition, in order to investigate the variability of the biomarker investigators will assess the 'measurement' error in all participants by performing a repeat 'second' scan in the same scanning session, and , in cases only, 'biological' variability by performing a repeat scan in controls 2-4 weeks later. Suitable patients based on trial inclusion criteria will be identified by the study PI and clinical collaborator and invited to receive one or two MRI scans from which cT1 and PDFF will be derived using Perspectum's LiverMultiScan software. Baseline scan will ideally be performed between 3 days (to allow for recovery from the procedure and time for biopsy results to become available) and 6 weeks following biopsy, to minimize the likelihood that the patient is in a significantly different pathophysiologic state on the baseline scan day than on the biopsy day. In order to ensure that the investigators capture information on normal variability and not related to intervention they will also capture and record basic information at both measurement timepoints (e.g. body weight, waist circumference, details of lifestyle interventions).

Eligibility

Inclusion Criteria:

• Male and female subjects aged between 18-75 years
• Ability to understand and sign a written informed consent form (ICF)
• Patients who have undergone a liver biopsy within the last 6 weeks because of clinical suspicion on NAFL-D

Exclusion Criteria:

• Prior or planned liver transplantation
• Patients who have undergone a laparoscopic or wedge liver biopsy, or biopsy taken from the left lobe
• Participation in an investigational new drug (IND) trial in the 30 days before enrolment (except those patients who were not administered the IND)
• Other known causes of chronic liver disease based on clinical criteria at the study

site, such as the following:

• Alcoholic liver disease
• Primary biliary cirrhosis
• Primary sclerosing cholangitis
• Autoimmune hepatitis
• Wilson's disease, hemochromatosis, iron overload
• Alpha-1-antitrypsin (A1AT) deficiency
• Hepatitis C Virus, Hepatitis B Virus
• History or diagnosis of cirrhosis and/or hepatic decompensation including ascites, hepatic encephalopathy or variceal bleeding
• Clinically relevant (more than 3 drinks per day on average for men and 2 for women) alcohol abuse within 12 months of liver biopsy and/or any recreational drugs
• Any contradiction or significant limitation to Magnetic Resonance imaging (MRI)

scanning including but not limited to the following:

• Claustrophobia preventing Magnetic Resonance imaging (requires 15-30 minutes in scanner)
• Pacemaker or another implanted electronic device
• Metal in body (such as aneurysm clip) that might produce artefact on abdominal MRI or might be adversely impacted by a high magnetic field
• Inability to lie flat, remain till, or briefly hold breath as necessary during MR imaging
• Medical condition likely to produce significant hypervolemia like congestive heart failure
• Severe obesity complicating positioning within MR scanner
• Concomitant medical illnesses per investigators discretion that would hamper patient's completion of the study or otherwise affect the collected data (such as HIV infection, recent major surgery, uncontrolled heart disease, concurrent infection or fever of unknown origin, illicit drug use, cancer)
• Clinically significant medical or psychiatric condition considered a high risk for participation in an investigational study
• Failure to give informed consent

Intervention

Device:
• LiverMultiscan
The Livermultiscan is a quick, 15 minute contrast free MRI scan that provided metrics to quantify liver health namely fat, iron and fibro-inflammation

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To demonstrate that a binary decision algorithm applied to cT1 can significantly identify patients whose liver biopsy results would qualify them for randomization in a clinical trial testing an investigational treatment for NASH	Mean cT1 (and PDFF) values for those with NAS=4&F2-3 (cases) and those with NAS<4 or F<2 (controls)	6 weeks
Secondary	To determine the measurement test-retest repeatability of cT1 and PDFF in the target patient population by examining the test-retest variability within a single scanning session	Difference between two replicates (Scan A and Scan B in same session) under the same measurement conditions expressed as the repeatability coefficient	1 day
Secondary	To determine the biological repeatability of cT1 and PDFF in the target patient population by examining the test-retest variability between scans acquired under the same conditions but 2-4 weeks apart	Difference between two scans (Scan 1 and Scan 2) under the same measurement conditions expressed as the repeatability coefficient	2-4 weeks
