NCT ID: NCT02272504

Last Updated: 2024-07-23

Basic Information

• Recruitment Status: COMPLETED
• Total Enrollment: 2500 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2014-08-31
• Study Completion Date: 2021-02-28

Brief Summary

The objective of this study is to evaluate the clinical effectiveness of biomarkers, alpha-fetoprotein (AFP), Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3), and des-gamma-carboxy prothrombin (DCP), for surveillance program patients whose hepatocellular carcinoma (HCC) development may be potentially missed by ultrasound (US). This study expects to demonstrate that addition of biomarkers will increase the detection rate by at least 10%.

Detailed Description

This study is a prospective randomized controlled trial (RCT) comparing surveillance for hepatocellular carcinoma with ultrasound alone versus ultrasound and standard biomarkers. The study will be conducted initially at UHN (TGH and TWH). One arm will undergo surveillance for hepatocellular carcinoma using ultrasound (US) alone and the other will undergo HCC surveillance with US plus biomarkers (BM). The biomarkers to be used will be AFP, AFP-L3 and DCP). Subjects will undergo surveillance at 6 monthly intervals for a minimum of 2 years and up to 4 years. The endpoints will be the comparative effectiveness, defined as sensitivity and specificity of detection of HCC. The comparisons of sensitivity, specificity, and other parameters with respect to tumor characteristics will be made among US alone, biomarkers alone, and combined use of US and biomarkers. The target population is individuals who have liver cirrhosis and no HCC detectable at enrollment into the study. The factors contributing to the cause of the cirrhosis will be recorded but will not play a role into subject eligibility for the study

Conditions

Study Groups

Standard of care arm

Chronic liver disease patients who are under going standard of care surveillance for the development of HCC as defined by AASLD guidelines.

No interventions assigned to this group

Biomarker Arm

Chronic liver disease patients who are under going standard of care surveillance for the development of HCC as defined by AASLD guidelines plus the addition of biomarker assays (AFP, AFP-L3 and DCP) every 6 months.

No interventions assigned to this group

Eligibility Criteria

Inclusion Criteria

• Patient who is able and willing to comply with study procedures, and signed and dated informed consent is obtained.

• Patients with a clinical suspicion of cirrhosis based on the investigator's evaluation with cirrhosis confirmed by one of the following: (see below for definition of cirrhosis). Etiology of cirrhosis will not be considered in determining inclusion in the study.
• Patients aged 18 years and older.
• Hep B Risk Score > 8 (table 1)

Exclusion Criteria

• • Patients who have confirmed HCC by CT/MRI when they enrolled. Patients who have previously had HCC but have been treated and have been recurrence free for 5 years are eligible.

• Patients with the other cancer(s)
• Pregnant Women
• Patients who have known diagnosis of mental incapacitation that affects their ability to consent.
• Patients who are likely to be transplanted within 1 year or MELD score greater than 20.
• Patients with total or direct bilirubin > 3x upper limit of normal
• Patients with uncontrollable ascites
• Glomerular Filtration Rate less than 60.
• Patients with ≥ Grade II of hepatic encephalopathy
• Patients who are being treated with warfarin (DCP test values are affected by warfarin)
• Patients who have any contraindication to any of the study procedures, products used or its constituents (e.g., renal failure or contrast allergy).
• Patients who suffer from claustrophobia or who have other contraindications to MRI
• Patients with cirrhosis who were successfully treated for hepatitis C more than 3 years prior. However, patients who are on study who are treated for their hepatitis C may continue in the study.

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
