CCI-779 in Treating Patients With Advanced Solid Tumors

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase I trial to study the effectiveness of CCI-779 in treating patients who have advanced solid tumors.

OBJECTIVES:

* Determine the safety, tolerability, and maximum tolerated dose (MTD) of CCI-779 in patients with advanced solid tumors (part I) who are not receiving anticonvulsant therapy.
* Determine the safety, tolerability, and MTD in patients with recurrent gliomas or brain metastases (part II) who are receiving anticonvulsant therapy.
* Determine the preliminary pharmacokinetic profile and antitumor activity of CCI-779 in these patients.

OUTLINE: This is an open-label, dose-escalation study.

* Part I: Patients receive CCI-779 IV over 30 minutes on days 1-5, followed by a 9 day rest period. Treatment courses repeat every 2 weeks in the absence of disease progression or unacceptable toxicity.

The maximum tolerated dose for part I is defined as the dose level at which 33% of patients experience dose limiting toxicity.

* Part II: Patients receive the same treatment schedule as part I. Three patients with CNS tumors are entered at the dose of CCI-779 determined to be the MTD in Part I. At least 3 patients are entered at each dose level in part II.

PROJECTED ACCRUAL: Approximately 20 patients will be accrued for part I for this study within 8 months, and 12 patients will be accrued for part II within 7 months.
