Last verified: December 2007
Open-label exloratory pharmacodynamic and pharmacogenomic study to evaluate teh biologic effects of 3 dose levels (1mg, 5 mg, and 15 mg) of temsirolimus administered orally once daily for approximately 4 weeks (+/- 2 weeks) before prostatectomy

Condition Intervention
Prostatic Neoplasms Drug: temsirolimus

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: An Open Label Study of Exploratory Pharmacogenomics and Pharmacologic Effects of Neoadjuvant Oral Temsirolimus in Newly Diagnosed Prostate Cancer Patients Undergoing Radical Prostatectomy Who Have a High Risk of Relapse

Further study details as provided by Wyeth is now a wholly owned subsidiary of Pfizer:

Primary Outcome Measures:
  • To determine the effects of oral temsirolimus on changes in phosphorylation state of proteins in the mTOR signaling pathway in tumor tissue and on phosphorylation state of mTOR pathway proteins and on global and targeted gene expression pattern PBMCs

Secondary Outcome Measures:
  • Determine effects of oral temsirolimus on global and targeted gene expression; compare effects in the tumor and PBMCs; obtain preliminary information on potential antitumor effects; evaluate PK using whole blood and tumor tissue.
  • To evaluate the relationship between PTEN status and the pharmacodynamic/pharmacogenomic effects of temsirolimus and to determine the effects of temsirolimus on changes in protein expression patterns in the plasma

Estimated Enrollment: 50
Study Start Date: January 2004
Study Completion Date: September 2007

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion criteria:

  • Histologically confirmed diagnosis of adenocarcinoma of the prostate gland via a minimum of 6 core biopsy samples.
  • Subjects must be a candidate for radical prostatectomy
  • No evidence of metastatic disease as determined by CT scans and bone scans

    • More criteria apply

Exclusion Criteria:

  • Subjects from whom sufficient diagnostic biopsy material is not available for full characterization of the tumor
  • Active Infection requiring antibiotic therapy, or serious intercurrent illness, active bleeding, or ongoing urinary tract infection necessitating rapid or emergent surgical resection
  • Subjects who have had hormonal injection or implants which will last longer than 6 months

    • More criteria apply
