OBJECTIVES: I. Determine the maximum tolerated dose of SU5416 in combination with irinotecan and cisplatin in patients with advanced solid tumors. II. Determine the quantitative and qualitative toxicity of this treatment regimen in terms of organ specificity, time course, predictability, and reversibility in this patient population. III. Determine the therapeutic response of this treatment regimen in these patients. IV. Evaluate the clinical pharmacokinetics and the relationship of kinetics to toxicity and response in this patient population treated with this regimen.
