Clinical Trial: Carboxyamidotriazole and Ketoconazole in Treating Patients With Advanced Cancers
This study is no longer recruiting patients.
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 carboxyamidotriazole and ketoconazole in treating patients with advanced cancers.

Study Design: Treatment
Study start: May 1998
OBJECTIVES: I. Determine the maximum tolerated dose of carboxyamidotriazole (CAI) in combination with ketoconazole in patients with advanced malignancies. II. Evaluate the toxic effects, safety, and efficacy of CAI in combination with ketoconazole. III. Determine the modulatory effects of ketoconazole on the pharmacokinetic profile of CAI. IV. Determine a pharmacodynamic model for CAI and ketoconazole with respect to potential gastrointestinal, hematologic, and neurotoxicities.
PROTOCOL OUTLINE: This is a dose escalation study. Patients receive oral carboxyamidotriazole (CAI) as a test dose on day 1. Patients receive oral ketoconazole on day 7, followed by CAI plus ketoconazole on day 8. CAI and ketoconazole are administered in combination on day 1 and days 3-28 of the first course. Ketoconazole is administered alone on day 2 of the first course. Subsequent courses begin at 28 day intervals in the absence of disease progression or unacceptable toxic effects. Cohorts of 3 patients are evaluated at each dose level prior to dose escalation. If one of three patients within a cohort experiences dose limiting toxicity (DLT), that dose level is expanded to incorporate six patients. If two or more patients experience DLT, the next lower dose is declared to be the maximum tolerated dose.
PROJECTED ACCRUAL: Up to 30 patients will be accrued for the study.
