Registry summary
Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.
This phase II trial studies how well androgen deprivation therapy and vorinostat followed by radical prostatectomy works in treating patients with prostate cancer that has not spread to other parts of the body. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as bicalutamide, goserelin acetate, and leuprolide acetate, may lessen the amount of androgens made by the body. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving androgen deprivation therapy and vorinostat before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

Arms1
Experimental
Treatment (Antihormone therapy and enzyme inhibitor therapy)
Patients receive bicalutamide PO QD for 1 month and leuprolide acetate IM or goserelin acetate SC once a month until surgery. Patients also receive vorinostat PO QD beginning on the first day of androgen depletion therapy and continuing for up to 8 weeks or until the day of surgery. Patients then undergo an open or laparoscopic radical prostatectomy. Patients with positive surgical margins undergo immediate adjuvant external beam radiotherapy to the prostatic fossa, based on the judgment of the treating physician.

Pathologic Complete Response at the Time of Surgery
Time frame · At 12 weeks
Registry description
The primary endpoint will be pathologic complete response at the time of surgery. This represents the proportion of patients with no evidence of disease in the prostate (ie, the absence of tumor in the posttherapy pathology specimen) at the time of radical prostatectomy. Pathologic complete response at the time of surgery is the primary endpoint for this study. A Simon 2-stage optimal design that differentiates between response probabilities of 0.05 and 0.20 will be used in the analysis of the pathological complete response at 12 weeks (Type I error 10% and power 90%). A maximum of 38 pts were planned for accrual onto this study. If zero or one response was observed, then the trial was to be stopped. The design had power 0.90 for a population response proportion to 0.20 using a one-sided 0.10 size test. pT2 indicates that the cancer is confined to the prostate, while pT3 indicates that there is an extraprostatic extension of the cancer.
Secondary outcomes(6)
Gleason Score
Time frame · Baseline
Registry description
A Gleason score is the sum of two numbers. Pathologist determines where the cancer is most prominent and assigns the primary grade, the secondary grade is assigned based on where the cancer is next most prominent. A score from one to five is assigned for each area based on how aggressive the tumor appears. A tumor with cell that appear close to normal is assigned a low Gleason score (six or below). A tumor with cells that appear clearly different from those of a normal prostate is assigned a high Gleason score (seven or above). A system of grading prostate cancer tissue based on how it looks under a microscope. Gleason scores range from 2 to 10 and indicate how likely it is that a tumor will spread. A low Gleason score means the cancer tissue is similar to normal prostate tissue and the tumor is less likely to spread; a high Gleason score means the cancer tissue is very different from normal and the tumor is more likely to spread.
