EGCG for Hepatocellular Carcinoma Chemoprevention

Summary

This phase II trial tests epigallocatechin gallate (EGCG) for its efficacy and safety in preventing development of hepatocellular carcinoma (HCC) in patients with liver cirrhosis.

Detailed Description

This study will evaluate whether EGCG favorably modulate an HCC risk biomarker (PLSec) with acceptable safety profile in patients with compensated cirrhosis and elevated HCC risk determined by clinical variable-based score (FIB-4 index) and PLSec. Sixty participants will be randomized (1:1) to either the study drub or placebo arm and receive the treatment for 24 weeks. The participants will orally take EGCG 600 mg capsules or placebo for the first 12 weeks. If an interim PLSec analysis at the end of week 8 is not improved without any dose-limiting adverse events, the dose will be increased to 800 mg for the second 12 weeks. If the interim PLSec is improved, 600 mg will be continued. After completing the 24-week treatment, change in the PLSec test with the treatment is calculated by comparing pre- and post-treatment serum samples in each patient, and the changes will be compared between the treatment arms (primary endpoint). Complete adverse event profiles will be recorded, and change in quality of life will be compared between the treatment arms (secondary endpoints). If optional paired liver biopsy tissues are obtained, changes in tissue-based HCC risk biomarker (PLS) and immunohistochemical markers of cell proliferation, neoplasm, senescence, and fibrogenesis will be determined, changes in the FIB-4 index and liver stiffness measurement will be determined, and association with incident HCC during the study period will be evaluated (exploratory endpoints).
