OBJECTIVES: Primary * Determine the effects of oral CCI-779 on changes in the phosphorylation state of proteins in the mammalian target of rapamycin (mTOR) signaling pathway in the tumor tissue of patients with newly diagnosed prostate cancer undergoing radical prostatectomy. * Determine the effects of this drug on changes in p70S6 kinase activity, phosphorylation state of mTOR pathway proteins, and on global and targeted gene expression patterns in the peripheral blood mononuclear cells (PBMCs) of these patients. Secondary * Determine the effects of this drug on global and targeted gene expression patterns in these patients. * Identify pharmacodynamic/pharmacogenomic surrogate markers of this drug in both tumor tissue and PBMCs and determine if blood may be used as a surrogate tissue source for biomarkers of drug activity in the tumor in these patients. * Determine, preliminarily, the potential antitumor effects of this drug in these patients. * Determine the pharmacokinetics of this drug in these patients. * Correlate phosphatase and tensin homolog (PTEN) gene status with the pharmacodynamic/pharmacogenomic effects of this drug in these patients. * Determine the effects of this drug on changes in protein expression patterns in the plasma of these patients. OUTLINE: This is a randomized, open-label, multicenter study. Patients are randomized to 1 of 3 treatment arms. Patients randomized to arm III are stratified according to tumor expression of phosphatase and tensin homolog (PTEN) gene mutations (negative vs positive). * Arm I: Patients receive oral CCI-779 once daily for a total of 8 weeks. * Arm II: Patients receive a higher dose of CCI-779 as in arm I. * Arm III: Patients receive a higher dose (higher than arm II) of CCI-779 as in arm I. Approximately 24-48 hours after the last dose of CCI-779, patients in all arms undergo radical prostatectomy. Patients are followed on day 7-10 and then at 4 weeks after study completion. PROJECTED ACCRUAL: A total of 40 patients (5 each for arms I and II and 30 for arm III) will be accrued for this study.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

15 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
