Brief Summary

Green tea extract contains ingredients that may slow the growth of certain cancers. It is not yet known whether green tea extract is more effective than a placebo when given before surgery in treating patients with bladder. This randomized phase II trial is studying green tea extract to see how well it works compared to a placebo when given before surgery in treating patients with nonmetastatic bladder cancer.

Outcome Measures

Primary Outcomes (1)

  • Epigallocatechin Gallate (EGCG) Levels in Nonmalignant Bladder Tissue (e.g., Normal-appearing Urothelium, Inflammatory Lesions in the Bladder, Sessile Noninvasive Bladder Tumors, and Papillary Noninvasive Bladder Tumors)

    Comparison of nonmalignant bladder tissue levels of EGCG between the placebo group and the EGCG groups combined using student t-test.

    up to 28 days

Secondary Outcomes (12)

  • Levels of EGCG in Malignant Bladder Tissue

    up to 28 days

  • Levels of Surrogate Intermediate Endpoint Biomarkers in Malignant and Nonmalignant Bladder Tissue Assessed by Immunohistochemistry

    up to 28 days

  • Serum Insulin Growth Factor-1 (IGF-1) Levels Assessed by ELISA

    Baseline and up to day 28

  • Levels of Other Catechins (Epicatechin Gallate, Epicatechin, and Epigallocatechin) Found in Polyphenon E Tumor Tissue Samples

    up to 28 days

  • Absolute Change for Baseline From EGCG in Serum Samples

    Baseline and up to 28 days

  • +7 more secondary outcomes

Study Arms (3)

Arm I (placebo)

PLACEBO COMPARATOR

Patients receive six oral placebo capsules once daily for 14-28 days.

Other: Laboratory Biomarker AnalysisOther: Pharmacological StudyDrug: Placebo

Arm II (polyphenon E, placebo)

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.

Dietary Supplement: Defined Green Tea Catechin ExtractOther: Laboratory Biomarker AnalysisOther: Pharmacological StudyDrug: Placebo

Arm III (polyphenon E, trans-urethral resection or cystectomy)

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.
