Androgen Deprivation Therapy and Vorinostat Followed by Radical Prostatectomy in Treating Patients With Localized Prostate Cancer

• Status: Completed
• Trial end date: 2010-06-01
• Target enrollment: 0
• Participant gender: Male

Summary

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.

Criteria

Inclusion Criteria:

• Histologic documentation of prostatic adenocarcinoma in 3 or more biopsy cores, of which at least 1 core demonstrates > 30% involvement with tumor; confirmation of localized disease by magnetic resonance imaging (MRI) with endorectal probe if available

• No evidence of distant disease on a:

• Computed tomography (CT) or MRI of the abdomen and pelvis

• Radionuclide bone scan (with plain film or MRI confirmation as clinically indicated)

• Appropriate candidate for radical prostatectomy

• Adequate cardiac function (evidence of cardiac disease should be evaluated to determine appropriateness of patient as a surgical candidate)

• Candidates may have a history of deep vein thrombosis, pulmonary embolism, and/or cerebrovascular accident, or require concomitant systemic anticoagulation, if otherwise deemed to be suitable for radical prostatectomy

• White blood cell (WBC) > 3000/uL

• Platelets > 150,000/uL

• Creatinine < 2 mg/dL

• Serum PSA < 100 ng/mL

• Bilirubin < 1.5 X ULN (institutional upper limits of normal)

• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) < 2 X ULN

• Karnofsky performance status > 70%

• Willingness to undergo pretreatment transrectal ultrasound-guided prostate needle biopsy (optional)

• Willingness to use adequate contraceptive methods during study therapy and for at least 3 months after completion of therapy

• Ability to understand and willingness to sign a written informed consent document

Exclusion Criteria:

• Evidence of small-cell, transitional-cell, or neuroendocrine pathologic features

• Prior hormonal therapy with (e.g. 5-alpha-reductase inhibitors, gonadotropin hormone releasing analogs, steroids, megestrol acetate, or nonstudy-related antiandrogens), chemotherapy, or herbal medications administered with the intent to treat the patient's malignancy

• Patients on valproic acid (a histone-deacetylase inhibitor) to treat prostate cancer are not eligible

• History of allergic reactions attributed to compounds of similar chemical or biological composition to vorinostat

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situation that would compromise compliance with study requirements

• Currently active secondary malignancy (as determined by the treating physician) other than non-melanoma skin cancer
