Brief 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 irinotecan plus raltitrexed in treating patients who have refractory solid tumors that have not responded to previous therapy.

Condition or disease Intervention/treatment Phase
Unspecified Adult Solid Tumor, Protocol Specific Drug: irinotecan hydrochloride Drug: raltitrexed Phase 1

Detailed Description:

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.
