Irinotecan Plus Raltitrexed in Treating Patients With Refractory Solid Tumors
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 irinotecan plus raltitrexed in treating patients who have refractory solid tumors that have not responded to previous therapy.
Unspecified Adult Solid Tumor, Protocol Specific
Drug: irinotecan hydrochloride
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase I Pharmacokinetic and Pharmacodynamic Trial of Irinotecan in Combination With Tomudex in Patients With Refractory Solid Malignancies|
|Study Start Date:||December 1997|
|Study Completion Date:||January 2001|
|Primary Completion Date:||October 2000 (Final data collection date for primary outcome measure)|
OBJECTIVES: I. Determine the maximum tolerated dose of irinotecan in combination with raltitrexed in patients with refractory solid tumors. II. Describe and quantify the toxic effects of this combination treatment regimen in a minimally pretreated patient population. III. Determine the pharmacokinetics of this combination treatment regimen. IV. Document any antitumor activity of this combination treatment regimen in this patient population.
OUTLINE: This is a dose escalation study of irinotecan and raltitrexed. Patients receive irinotecan IV over 90 minutes on days 1 and 8 followed by raltitrexed IV over 15 minutes on day 1. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients each receive escalating doses of irinotecan and raltitrexed 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. Additional cohorts receive raltitrexed on day 2 rather than day 1 near the final dose levels of the combination drugs.
PROJECTED ACCRUAL: A maximum of 36 patients will be accrued for this study within 1 year.
