UCN-01, Fluorouracil, and Leucovorin in Treating Patients With Metastatic or Unresectable Solid Tumors
RATIONALE: UCN-01 may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining UCN-01 with chemotherapy may kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of combining UCN-01, fluorouracil, and leucovorin in treating patients who have metastatic or unresectable solid tumors.
Unspecified Adult Solid Tumor, Protocol Specific
Drug: leucovorin calcium
|Study Design:||Primary Purpose: Treatment|
|Official Title:||A Phase I Pharmacologic Trial Of Infusional UCN-01 Given With A Weekly Schedule Of 5-Fluorouracil And Leucovorin|
|Study Start Date:||August 2002|
- Determine the maximum tolerated dose of fluorouracil when given in combination with UCN-01 and leucovorin calcium in patients with metastatic or unresectable solid tumors.
- Determine the clinical toxic effects of this regimen in these patients.
- Determine the pharmacokinetics of these drugs in these patients.
- Correlate, if possible, the pharmacokinetics of these drugs with clinical toxicity in these patients.
- Assess the pharmacodynamic effects of these drugs in these patients.
- Assess any clinical activity of this regimen in patients with measurable disease.
OUTLINE: This is a dose-escalation study of fluorouracil (5-FU).
Patients receive leucovorin calcium (CF) IV over 2 hours and 5-FU IV (at the midpoint of CF administration) on day 1, followed by UCN-01 IV over 36-72 hours, on weeks 1-3. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of 5-FU until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. The recommended phase II dose (RPIID) is defined as the dose preceding the MTD. At least 6 additional patients are treated at the RPIID.
PROJECTED ACCRUAL: A total of 24 patients will be accrued for this study within 16 months.
