Measure
Polyphenon E 1600 mg/Day
Drug: Polyphenon E Polyphenon E capsules containing 200 mg of epigallocatechin-gallate. Four capsules twice a day. Polyphenon E: There will be 3 dose levels and for each dose level, there will be 6 subjects who will receive the study drug and 2 subjects who will be randomized to take placebo. Dosing will be escalated sequentially contingent on the safety profile of previous doses. Safety data from all participants receiving Polyphenon® E in the preceding arm will be evaluated and considered acceptable prior to escalation to the next higher dose. PK analyses will be also performed as each arm is completed. It is necessary to confirm EGCG pharmacokinetics in the event that the primary outcome measure of virologic response is not observed for each arm. For each PK visit on Study Days 1 and 14, a total of 10 blood samples will be obtained per subject.
Polyphenon E 2400 mg/Day
Drug: Polyphenon E Polyphenon E capsules containing 200 mg of epigallocatechin-gallate. Six capsules twice a day. Polyphenon E: There will be 3 dose levels and for each dose level, there will be 6 subjects who will receive the study drug and 2 subjects who will be randomized to take placebo.

Polyphenon E 3200 mg/Day
Drug: Polyphenon E Polyphenon E capsules containing 200 mg of epigallocatechin-gallate. Eight capsules twice a day.

Measure
Polyphenon E 1600 mg/Day
n=6 participants at risk
Drug: Polyphenon E Polyphenon E capsules containing 200 mg of epigallocatechin-gallate. Four capsules twice a day. Polyphenon E: There will be three dose levels, each consisting of 6 participants. Dosing will be escalated sequentially contingent on the safety profile of previous doses. Safety data from all participants receiving Polyphenon® E in the preceding arm will be evaluated and considered acceptable prior to escalation to the next higher dose. PK analyses will be also performed as each dose level is completed. It is necessary to confirm EGCG pharmacokinetics in the event that the primary outcome measure of virologic response is not observed for each dose level. For each PK visit on Study Days 1 and 14, a total of 10 blood samples will be obtained per subject.
Polyphenon E 2400 mg/Day
