Combination Chemotherapy In Treating Patients With Advanced Cancer

2014-08-27 03:58:27 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of combining gemcitabine, fluorouracil-uracil and leucovorin in treating patients who have advanced cancer that has not responded to previous therapy.

Description

OBJECTIVES:

- Determine the maximum tolerated doses of gemcitabine, fluorouracil-uracil (UFT), and leucovorin calcium in patients with advanced refractory cancer.

- Assess the toxicity of this combination regimen in this patient population.

- Evaluate this regimen in terms of response rate, response duration, and overall survival in these patients.

OUTLINE: This is a dose escalation study of gemcitabine and fluorouracil-uracil.

Patients receive gemcitabine IV over 30 minutes on days 1, 8, and 15. Patients receive oral leucovorin calcium immediately followed by oral fluorouracil-uracil (UFT) three times a day on days 1-21. Courses are repeated every 28 days. Treatment continues in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of gemcitabine and UFT until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicities.

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