Characterization of Baseline Biomarker Variability in Participants With Hepatocellular Carcinoma (MK-0000-215)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to characterize the baseline variability of a panel of tissue (tumor and adjacent) and blood-based biomarkers obtained from participants with hepatocellular carcinoma (HCC). The primary hypothesis is that the upper bound of the 80% Confidence Interval of log beta-catenin protein or messenger RNA (mRNA) expression from one core needle biopsy (CNB) equivalent is =< 0.65.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Imaging<br>Magnetic resonance imaging (MRI) of HCC tumor. | Procedure: MRI<br>* Participants undergo volumetric & diffusion weighted (DW) MRI. Participants are scanned twice, with an intervening fifteen minute walk between the scans.<br>Procedure: Blood Samples<br>* Blood is collected from participants during screening Visit 1 - 24.5 ml, and follow up Visit 4 - 5.5 ml.<br>|
| Experimental: Pathology<br>Pathology samples from surgical resection of HCC tumor and adjacent liver. | Procedure: Pathology<br>* Participants who are undergoing surgical resection of HCC per their standard of care treatment, will submit tumor samples for biomarker analysis.<br>Procedure: Blood Samples<br>* Blood is collected from participants during screening Visit 1 - 24.5 ml. During Visit 3, blood samples totaling 22 ml, are collected at least 6-18 hours post-resection, and every other day up to a week until discharge. At follow up Visit 4, 5.5 ml of blood is collected.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Expression Levels of Beta-catenin mRNA From Core Needle Biopsy (CNB) Equivalents of Resected HCC. | Resected tumors were fixed with formalin in paraffin embedded (FFPE) blocks, which were used to prepare multiple serial slide sections. The sections were to be analyzed for beta-catenin messenger RNA (mRNA) by quantitative reverse transcription polymerase chain reaction (qRT-PCR). | Visit 3, approximately 7 days after screening Visit 1. | 
| Expression Levels of Beta-catenin Protein From Core Needle Biopsy (CNB) Equivalents of Resected HCC. | Resected tumors were fixed in FFPE blocks, which were used to prepare multiple serial slide sections. The sections were to be analyzed for beta-catenin protein by automated image analysis. | Visit 3, approximately 7 days after screening Visit 1. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Tumor Volumes From Repeated MRI Measurements of HCC. | Two volumetric MRI and diffusion weighted (DW) MRI scans were performed without contrast on each participant. The two scans were separated by 10 to 15 minutes, and each scan was read by a separate reader to determine the volume of each tumor. The mean of log tumor volume is presented, based on tumors as observation units. | Visit 2, approximately 7 days after screening Visit 1. | 
| Median Apparent Diffusion Coefficient (Median ADC) of Tumors From Repeated MRI Measurements of HCC. | Two volumetric MRI and diffusion weighted (DW) MRI scans were performed without contrast on each participant. The two scans were separated by 10 to 15 minutes, and each scan was read by a separate reader to derive a Median ADC for each tumor. The mean of the Median ADCs is presented based on tumours as observation units. | Visit 2, approximately 7 days after screening Visit 1. | 
| Expression Levels of Beta-catenin mRNA From CNB Equivalents of Liver Adjacent to HCC. | Tissues adjacent to resected tumors were fixed in FFPE blocks, which were used to prepare multiple serial slide sections. The sections were to be analyzed for beta-catenin mRNA by qRT-PCR. | Visit 3, approximately 7 days after screening Visit 1. | 
| Expression Levels of Beta-catenin Protein From CNB Equivalents of Liver Adjacent to HCC. | Tissues adjacent to resected tumors were fixed in FFPE blocks, which were used to prepare multiple serial slide sections. The sections were to be analyzed for beta-catenin protein by automated image analysis. | Visit 3, approximately 7 days after screening Visit 1. | 
| Expression Levels of Low Density Lipoprotein Receptor (LDL-R) in Resected HCC and Adjacent Liver From Whole Tissue Sections. | Resected tumors and adjacent tissues were fixed in FFPE blocks, which were used to prepare multiple serial slide sections. The sections were to be analyzed for LDL-R protein by automated image analysis. | Visit 3, approximately 7 days after screening Visit 1. |
