- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Arm I (placebo) (Type: PLACEBO_COMPARATOR): Patients receive six oral placebo capsules once daily for 14-28 days.
- Arm II (polyphenon E, placebo) (Type: EXPERIMENTAL): Patients receive four oral polyphenon E capsules and two oral placebo capsules once daily for 14-28 days in the absence of unacceptable toxicity.
- Arm III (polyphenon E, trans-urethral resection or cystectomy) (Type: EXPERIMENTAL): Patients receive six oral polyphenon E capsules once daily for 14-28 days in the absence of unacceptable toxicity. After completion of study treatment, patients undergo trans-urethral resection of bladder tumor or cystectomy.
