Spots Global Cancer Trial Database for Irinotecan and Cisplatin With or Without Amifostine in Treating Children With Solid Tumors That Have Not Responded to Previous Therapy

Study Description

Brief Summary: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Chemoprotective drugs such as amifostine may protect normal cells from the side effects of chemotherapy. Phase I trial to study the effectiveness of irinotecan and cisplatin with or without amifostine in treating children who have solid tumors that have not responded to previous therapy.

Detailed Description: PRIMARY OBJECTIVES: I. Determine the maximum tolerated dose (MTD) of irinotecan when administered with cisplatin, with or without amifostine, to children with refractory solid tumors. II. Determine the dose limiting toxicities of the combination of irinotecan and cisplatin, with and without amifostine, in this patient population. III. Determine the pharmacokinetics of cisplatin with and without amifostine in these patients. IV. Quantify the leukocyte DNA-platinum adduct formation, with and without amifostine, and correlate it with response and toxicity in these patients. V. Determine the safety and efficacy of the doses and schedules of administration to be used in phase II clinical trials. OUTLINE: This is a dose escalation study of irinotecan. Treatment A: Patients receive cisplatin IV over 1 hour followed immediately by irinotecan IV over 90 minutes on days 1, 8, 15, and 22. Courses repeat every 6 weeks. Treatment continues for a minimum of 2 courses in the absence of unacceptable toxicity or disease progression. Treatment B: Patients receive therapy as in treatment A. In addition, amifostine IV is administered over 15 minutes immediately before cisplatin. Cohorts of 3-6 patients receive escalating doses of irinotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose limiting toxicities. Once the MTD of treatment A is determined, additional patients are accrued to determine the MTD of treatment B. If myelosuppression is the dose limiting toxicity of treatment A, then stratum 1 closes and stratum 2 opens and these patients with less prior therapy receive treatment A. Treatment B is then only open to stratum 3 patients. Patients are followed every 6 months for 4 years, then annually thereafter. PROJECTED ACCRUAL: A total of 3-30 patients will be accrued for this study within 2.5 years.
