Defined Green Tea Catechin Extract in Preventing Liver Cancer in Participants With Cirrhosis
Study Details
Study Description
Brief Summary
This phase I trial studies the side effects and best dose of defined green tea catechin extract and to see how well it works in preventing liver cancer in participants with cirrhosis. Higher levels of the molecule gamma-OHPdG may be found in participants with cirrhosis, which may mean a higher risk of the development of liver cancer. Defined green tea catechin extract may work better to lower levels of gamma-OHPdG and prevent the development of liver cancer.

Detailed Description
PRIMARY OBJECTIVES:
-
To establish maximum tolerated dose (MTD) and to collect safety data of defined green tea catechin extract (Polyphenon E/epigallocatechin gallate [EGCG]) treatment in participants with cirrhosis.
-
To determine the effects of Polyphenon E/EGCG treatment on the suppression of gamma-hydroxy-1,N(2)-propanodeoxyguanosine (gamma-OHPdG) levels in cirrhotic liver.
SECONDARY OBJECTIVES:
-
To collect Polyphenon E/EGCG pharmacokinetic data in participants with cirrhosis.
-
To study the correlation between gamma-OHPdG levels and mutation frequency and deoxyribonucleic acid (DNA) damage spectrum in the p53 and beta-catenin genes in cirrhotic liver tissue.
-
To estimate the fraction of participants with liver cirrhosis that have high levels of gamma-OHPdG.
EXPLORATORY OBJECTIVES:
-
To assess the effects of Polyphenon E/EGCG on the grade of cirrhosis as measured by FibroScan and Fibrosis-4 (FIB-4) score.
-
To develop a liquid chromatography-mass spectrometry (LC-MS) and/or enzyme-linked immunosorbent assay (ELISA)-based method for detecting urinary and blood gamma-OHPdG, to correlate with liver gamma-OHPdG levels.
-
To evaluate any hepatocellular carcinoma (HCC) development during the treatment.
OUTLINE: This is a dose-escalation study.
Participants receive defined green tea catechin extract orally (PO) once daily (QD) or twice daily (BID) for 24 weeks in the absence of disease progression or unacceptable toxicity.
After completion of study intervention, participants are followed up at 28 days.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose of Polyphenon E [Up to 4 weeks]
Will be defined as the dose at which =< 1 subjects out of 6 experiences a grade 3 or higher toxicity based on Common Terminology Criteria for Adverse Events (CTCAE) criteria.
- Change in gamma-OHPdG expression in cirrhotic liver [Baseline up to 24 weeks]
Will be assessed by immunohistochemistry (IHC). Will use a nonparametric Wilcoxon test to compare the post-pre differences to zero.
Secondary Outcome Measures
- Fraction of patients with liver cirrhosis that have high levels of gamma-OHPdG [Up to 24 weeks]
Will use descriptive statistics.
- Change in mutation frequency in cirrhotic liver tissue [Baseline up to 24 weeks]
The mutation frequencies will be correlated with the change of gamma-OHPdG level in liver tissue. Will use graphics and a nonparametric correlation measure such as Spearman's correlation.
- Polyphenon E pharmacokinetic data in blood and urine in patients with cirrhosis [Prior to and at 1.5, 3.5, and 8.5 hours after the first dose of Polyphenon E on day 1]
Clearance of Polyphenon E will be compared among cirrhotic liver patients in this study and results from this population will be compared with non-cirrhotic historical control participants.
Other Outcome Measures
- Grade of cirrhosis [Up to 24 weeks]
Will be assessed by FibroScan and Fibrosis-4 score.
- Liquid chromatography-mass spectrometry (LC-MS) and/or enzyme-linked immunosorbent assay (ELISA)-based method for detecting gamma-OHPdG [Up to 24 weeks]
The research urine samples at screen 2 and research blood samples collected at visit 1, visit 2, and Visit 3 will be used to develop a non-invasive LC-MS and/or ELISA-based method to quantify gamma-OHPdG in urine and blood samples of collected from trial participants. Descriptive statistics (n; minimum [min]; maximum [max]; mean; median; standard deviation [SD] for continuous variables; and n, frequency for categorical variables) will be used to summarize participants demographics. Participants safety data will be tabulated according to the symptom and grade. Estimates will be presented with their 95% confidence intervals.
- Incidence of hepatocellular carcinoma [At baseline and 24 weeks]
Evaluated using ultrasound/computed tomography (CT)/magnetic resonance imaging (MRI).
Eligibility Criteria

-
Green tea has been consumed by humans for thousands of years and teratogenic or abortifacient effects have not been reported; however, subjects in this study will take high doses of Polyphenon E; the teratogenic or abortifacient effects of high dose Polyphenon E is unknown; therefore pregnant women are excluded from this study; because there is an unknown but potential risk for adverse events (AEs) in nursing infants secondary to treatment of the mother with Polyphenon E, breastfeeding should be discontinued if the mother is treated with this study agent
