Brief Summary

This phase II trial is studying how well vorinostat works in treating patients with progressive metastatic prostate cancer. Drugs used in chemotherapy, such as vorinostat, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Conditions

Recurrent Prostate Cancer; Stage IV Prostate Cancer

Outcome Measures

Primary Outcomes (1)

• Proportion of Patients Who do Not Demonstrate Disease Progression

  Fisher's Exact Test will be used.

  At 6 months

Secondary Outcomes (5)

• Incidence of Toxicity

  Up to 3 years

• Rate of PSA Decline

  Up to 3 years

• Progression-free Survival

  From the start of treatment to time of progression, assessed up to 3 years

• Median Survival

  Up to 3 years

• Objective Response Rate

  Up to 3 years

Study Arms (1)

Treatment (vorinostat)

EXPERIMENTAL

Patients receive oral vorinostat (SAHA) once daily on days 1-21. Treatment repeats every 21 days for at least 4 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve complete response (CR) after 4 courses receive an additional 3 courses. All other patients may continue treatment in the absence of disease progression or unacceptable toxicity. Blood samples are taken on day 15 of course 1, day 1 of course 2, during the last week of course 4, and at completion of study treatment. Blood is examined for interleukin (IL)-6, IL-6 receptor, and gp130 levels.

Eligibility Criteria

• Age: 18 Years+
• Sex: male
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• A histologic or cytologic diagnosis of prostate cancer
• Metastatic prostate cancer with measurable and/or bony disease that has progressed despite androgen deprivation therapy and one prior chemotherapy for castrate metastatic disease; all patients must have PSA progression defined as:
• At least 2 rises in PSA to be documented over a reference value (measure 1); the first rising PSA (measure 2) must be taken at least 7 days after the reference value; a third confirmatory PSA measure is required to be greater than the second measure and must be obtained at least 7 days after the 2nd measure; if this is not the case, a fourth PSA is required to be taken and be greater then the 2nd measure
• All patients must have a minimum PSA of \>= 5 ng/ml
• ECOG performance status of 0-2
• Testosterone \< 50 ng/dL; patients must continue primary androgen deprivation with an LHRH analogue if they have not undergone orchiectomy
• No investigational or commercial agents (other than LHRH analogue) or therapies including other hormonal agents such as megestrol acetate (unless low dose given for hot flashes), antiandrogens or herbal medications may be administered with the intent to treat the patient's malignancy
• Four weeks must have elapsed since major surgery
• Prior radiotherapy is allowed as long as the bone marrow function is adequate and at least 4 weeks has elapsed since completion of radiation; no prior radiopharmaceuticals are allowed
• Life expectancy of greater than 6 months
• Ability to understand and the willingness to sign a written informed consent document that is approved by the Institutional Human Investigation Committee (HIC)
• Patients must have normal organ and marrow function as defined below obtained within two weeks from treatment initiation:
• Leukocytes \>= 3,000/mcL
• Absolute neutrophil count \>= 1,500/mcL
• Platelets \>= 100,000/mcL

You may not qualify if:

• Significant cardiovascular disease including congestive heart failure (New York Heart Association Class III or IV), active angina pectoris or recent myocardial infarction (within the last 6 months)
• Patients on Valproic Acid (a histone deacetylase inhibitor) must have stopped taking it at least 2 weeks prior to registration
• Oral anti-androgens must be stopped; no washout period is necessary prior to enrollment if anti-androgens were used as second line therapy and not as part of combined androgen deprivation; in the unlikely case that a patient may have continued on antiandrogen therapy as part of combined androgen deprivation and has never had antiandrogen withdrawal despite progression on combined androgen deprivation then a washout period will be needed (4 weeks for flutamide and 6 weeks for bicalutamide or nilutamide) prior to study enrollment
• Patients who have developed progression as defined in this protocol on stable doses of oral corticosteroids are eligible; the steroids may be continued
• No "currently active" second malignancy other than non-melanoma skin cancer; patients are not considered to have a "currently active" malignancy if they have completed therapy and are considered by their physician to be with no evidence of disease
• Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; however, brain scans will not be required as part of the pre-study workup
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to SAHA
• 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 situations that would limit compliance with study requirements; patients with history of HIV receiving combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with SAHA; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy
• Patients with the following history or clinical findings require ADDITIONAL diagnostic TESTING:
• Patients who require diuretics for reasons other than hypertension, digoxin for reasons other than atrial fibrillation, or patients with a history of mild to moderate congestive heart failure
• Patients with the following EKG results:
• Significant q waves (greater than 3 mm or greater than 1/3 the height of the QRS complex
• ST elevation or depressions of greater than 2 mm that are not attributable to hypertension strain
• The absence of a regular sinus rhythm
• The presence of a bundle block

Limitations and Caveats

The primary objective was to determine the number of patients wtih progression-free survival at 6 months. Unfortunately all eligible patients were off therapy before the 6 month time point.
