Study Objectives / Outcomes
Primary:
  • To determine the effects of oral temsirolimus on changes in the phosphorylation state of proteins in the mTOR signaling pathway in the tumor tissue.
  • To determine the effects of oral temsirolimus on changes on the phosphorylation state of mTOR pathway proteins and on global and targeted gene expression patterns in the PBMCs.

Secondary:
  • To determine the effects of oral temsirolimus on global and targeted gene expression patterns in the tumor tissue.
  • To compare the effects of temsirolimus in the tumor and in PBMCs in an attempt to identify pharmacodynamic/pharmacogenomic surrogate markers of temsirolimus, and to determine if blood may be used as a surrogate tissue source for biomarkers of drug activity in the tumor.
  • To obtain preliminary information on potential antitumor effects of temsirolimus.
  • To evaluate pharmacokinetics using whole blood and tumor tissue (if sufficient tissue is available).
  • To evaluate the relationship between PTEN status and the pharmacodynamic/pharmacogenomic effects of temsirolimus.
  • To determine the effects of temsirolimus on changes in protein expression patterns in the plasma.

Enrollment Eligibility

Inclusion Criteria:1) Histologically confirmed diagnosis of adenocarcinoma of the prostate gland via a minimum of 6 core biopsy samples.

2) Subjects must be candidates for radical prostatectomy.

3) No evidence of metastatic disease as determined by computed tomography (CT) scans and bone scans.

4) Subjects defined as high risk for relapse based on either of the following criteria: a. Any 1 of the following: 1. Stage >/= T2C or 2. Gleason score > 7 or Pre-hormonal therapy prostate-specific antigen (PSA) > 20 or b. Any 2 of the following: 1. Gleason >/= 7 2. Pre-hormonal therapy PSA 10-20 3. Greater than 50% of total biopsy cores involved with cancer.

5) No prior chemotherapy or radiation therapy.

6) Initial hormone therapy must be within 6 weeks prior to study entry.

7) ECOG performance status 0-1.

8) ANC >/= 1500/mm3, Platelet >/= 100K/mm3, Hgb >/= 10 g/dL

9) Creatinine </= 1.5 x ULN

10) Bilirubin </= 1.5 x ULN, AST and ALT </= 2 x ULN

11) Signed informed consent

12) Subjects with partners of childbearing potential must be willing to use a medically acceptable and effective method of contraception throughout the study and for 12 weeks after study completion.

13) Men aged 18 years or older

Exclusion Criteria:1) Subjects from whom sufficient diagnostic biopsy material is not available for full characterization of the tumor.

2) Active infection requiring antibiotic therapy, or serious intercurrent illness, active bleeding, or ongoing urinary tract infection necessitating rapid or emergent surgical resection.

3) Severely immunocompromised subjects, including those known to be human immunodeficiency virus (HIV) positive.

4) Subjects with acute or chronic hepatitis B (HBsAg) or C (anti-HCV).

5) The use of immunosuppressive agents, including intravenous (IV) corticosteroids within 3 weeks of screening.

6) Presence of unstable angina, recent myocardial infarction (within the previous 6 months), or use of ongoing maintenance therapy for life-threatening ventricular arrhythmia, known pulmonary hypertension, or pneumonitis.

7) History of malignancy in the 5 years before study entry, except basal cell and squamous cell skin cancer.

8) Subjects who have had an Orchiectomy.

9) Subjects who have had hormonal injection or implants, which will last longer than six months.

10) Subjects who have had antiandrogen treatment within 28 days prior to study entry.

11) Any other major illness that in the investigator's judgment will substantially increase the risk associated with the subject's participation in this study.

12) Concomitant therapy with any other experimental drug.

13) Therapy with other experimental drugs within 1 month of study entry.

14) Major surgery within 3 months of study entry.

15) Unwillingness or inability to comply with procedures required in this protocol.
