A phase I single-arm, multicenter pilot study aimed at validating γ-OHPdG as a biomarker and testing the effects of Polyphenon E® on its levels in patients with cirrhosis

The Schema is a timeline of the study. It indicates start/end points, visits expected, major testing to be done, and any other information that is crucial to understanding how the study was completed.

  • Pre-Screen: Chart Review

    Medical charts are reviewed by a pathologist for eligibility.
  • Screen 1: Eligibility

    Medical charts are reviewed by a pathologist for eligibility.
  • Pre-Screen: Chart Review

    Participants with a diagnosis of liver cirrhosis are seen in clinic: Informed consent, history/physical/conmed review, CT or MRI, FibroScan®, clinical labs, Child Pugh score, pregnancy test, questionnaires, eligibility review
  • Study Visit 1: Week 1 Day 1

    Participants with high levels of γ-OHPdG (IHC ≥3) meeting eligibility criteria receive Polyphenon E according to the dose escalation schema 3+3 design plus expansion cohort to 24 for Maximum Tolerated Dose:
    • 400 mg EGCG QD
    • 400 mg EGCG BID
    • 600 mg EGCG BID
    • 800 mg EGCG BID
    • 1000 mg EGCG BID
    Physical, conmed/AE review, clinical labs, dispense agent, urine/blood collection for PK
  • Weekly or bi-weekly (depending on assigned dose, clinical stability, and liver biochemical stability of the participant) liver function tests
  • Study Visit 2: Week 13 ± 3 Days

    Mid-study clinic visit: Physical, conmed/AE review, clinical labs, dispense agent
  • Weekly or bi-weekly (depending on assigned dose, clinical stability, and liver biochemical stability of the participant) liver function tests
  • Study Visit 3: Week 25 ± 3 Days

    Last day of agent: Physical exam, conmen/AE review, clinical labs, Child Pugh score, CT or MRI, FibroScan, liver biopsy testing for γ-OHPdG
  • Study Visit 4: Week 28 ± 3 Days

    Follow-up: Physical exam, clinical labs
  • Primary Objectives:

    • To establish maximum tolerated dose (MTD) and to collect safety data of Polyphenon E/EGCG treatment in patients with cirrhosis.
    • To determine the effects of Polyphenon E/EGCG treatment on the suppression of γ-hydroxy-1,N(2)-propanodeoxyguanosine (γ-OHPdG) levels in cirrhotic liver.

    Secondary Objectives:

    • To collect Polyphenon E/EGCG pharmacokinetic data in patients with cirrhosis.
    • To determine the effects of Polyphenon E/EGCG treatment on the suppression of γ-hydroxy-1,N(2)-propanodeoxyguanosine (γ-OHPdG) levels in cirrhotic liver by LC-MS assay from baseline to post-treatment.
    • To estimate the fraction of patients with liver cirrhosis that have high levels of γ-OHPdG.

    Exploratory Objective:

    • To assess the effects of Polyphenon E/EGCG on the grade of cirrhosis as measured by FibroScan and FIB-4 score.
    • To develop an LC-MS and/or ELISA-based method for detecting urinary and blood γ-OHPdG, to correlate with liver ɣ-OHPdG levels.
    • To evaluate any HCC development during the treatment.
