Clinical Trial Summary

RATIONALE: Everolimus may stop the growth of tumor cells by stopping blood flow to the tumor. Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Combining everolimus with gefitinib may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with gefitinib and to see how well they work in treating patients with progressive glioblastoma multiforme or (progressive metastatic prostate cancer closed to accrual 10/19/06).

Description:

OBJECTIVES:

Primary

• Determine the maximum tolerated dose of everolimus when given in combination with gefitinib in patients with progressive glioblastoma multiforme or (progressive castrate metastatic prostate cancer -closed to accrual as of 10/19/2006). (Phase I)

• Determine the safety and efficacy of this regimen in patients with progressive glioblastoma multiforme or (progressive castrate metastatic prostate cancer - closed to accrual as of 10/19/2006). (Phase II)

Secondary

• Determine whether a pharmacokinetic interaction exists between everolimus and gefitinib in patients treated with this regimen.

• Determine the association between clinical outcomes and markers that may predict sensitivity of a tumor in patients treated with this regimen.

• Determine the pharmacodynamic effects of this regimen on post-therapy tumor specimens and peripheral blood mononuclear cells from these patients.

OUTLINE: This is a phase I, open-label, non-randomized, dose-escalation study of everolimus followed by a phase II study.

• Phase I: Patients receive oral everolimus on day 1 and oral gefitinib once daily on days 8-21. Beginning on day 22, patients receive oral everolimus once weekly and oral gefitinib once daily. Treatment with the combination continues in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of everolimus 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 toxicity.

• Phase II (prostate cancer patients only) (closed to accrual as of 10/19/2006): Patients receive oral everolimus (at the MTD determined in phase I) once weekly and oral gefitinib once daily. Treatment continues in the absence of disease progression or unacceptable toxicity.

• New or progressive (25% bidimensional increase) soft tissue masses on CT scan or MRI

• New or prior lesions that have increased in size by physical examination

• Patients who had prior interstitial brachytherapy or stereotactic radiosurgery must have confirmation of true disease progression (rather than radiation necrosis) by positron-emission tomography scan, thallium scanning, magnetic resonance spectroscopy, or surgical documentation

• A minimum of 3 rising levels of prostate-specific antigen (PSA) that are obtained 1 or more weeks apart OR 2 rising PSA values obtained more than 1 month apart with at least a 25% increase over the range of values

• New or progressive (25% bidimensional increase) soft tissue masses on CT scan or MRI

• New metastatic lesions

• Patients on an antiandrogen as part of initial therapy must show disease progression after discontinuation of the antiandrogen
