Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving the drugs in different ways may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of gemcitabine given directly into the bladder in treating patients who have recurrent or refractory bladder cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVES: I. Determine the maximum tolerated dose of intravesical gemcitabine in patients with recurrent or refractory superficial bladder cancer. II. Determine the dose-limiting toxicity and other toxic effects of this regimen in these patients. III. Assess any responses in patients treated with this regimen.

OUTLINE: This is a dose-escalation, multicenter study. Patients receive intravesical gemcitabine that is left in the bladder for 2 hours and then removed on day 1. Treatment continues every 7 days for 6 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of intravesical gemcitabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 6 patients experience dose-limiting toxicity. Patients are followed every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 3-36 patients will be accrued for this study.
