Irinotecan

Sponsored by: University of Chicago Cancer Research Center and National Cancer Institute (NCI)

RATIONALE: Thalidomide may stop the growth of cancer by stopping blood flow to the tumor. Drugs used in chemotherapy such as irinotecan use different ways to stop tumor ceils from dividing so they stop growing or die. Combining thalidomide with irinotecan may kill more tumor cells.

PURPOSE: Randomized phase I trial to study the effectiveness of combining thalidomide with irinotecan in treating patients who have metastatic or unresectable solid tumors.

Study Type: Interventional

Study Design: Treatment

OBJECTIVES:

* Determine whether thalidomide alters the pharmacokinetics of irinotecan in patients with advanced solid tumors.

* Determine whether irinotecan alters the pharmacokinetics of thalidomide in these patients.

* Determine the toxicity of this regimen in these patients.

* Determine the observed antitumor response in patients treated with this regimen.

OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms.

* Arm I: Patients receive irinotecan IV over 90 minutes on days 1 and 22 and oral thalidomide once daily on days 15-28.

* Arm II: Patients receive irinotecan as in arm I and oral thalidomide once daily on days -6 to 7. All patients undergo disease reevaluation at 6 weeks. Patients with stable or responsive disease may receive additional courses comprising irinotecan IV on day 1 and oral thalidomide once daily on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Ages eligible for study: 18 years and above, both genders
