You may be eligible if
All patients must have histologically or cytologically confirmed adenocarcinoma of the prostate
Patients with castrate and non-castrate levels of testosterone are eligible as defined below.
Patients with castrate level of testosterone (Group A- androgen independent disease) need to meet the following criteria:
Progressive disease based on any one of the following
You may not be if
1. PSA - a minimum of 3 consecutive rising levels, with an interval of \> 1 week between each determination. The last determination must have a minimal value of \> 4 ng/ml and be determined within two weeks prior to registration.
2. Measurable Disease: Patient showing new or progressive soft tissue masses on CT or MRI scans are eligible.
3. Radionuclide bone scan: New metastatic lesions.
Serum testosterone \< 50 ng/ml, determined within two weeks prior to starting treatment
Maintaining castrate status: Patients who have not undergone surgical orchiectomy should continue on medical therapies \[i.e. gonadotropin releasing hormone analogs (GnRH analogs) to maintain castrate levels of serum testosterone. Patients who are receiving an anti-androgen as part of their first-line hormonal therapy must have shown progression of disease off of the anti-androgen prior to enrollment. Patients must discontinue Megestrol Acetate (MEGACE) and show progression of disease off of this medication.
No prior chemotherapy except for adjuvant or neo-adjuvant therapy given \> than 3 years prior to enrollment
No more than one prior course of palliative radiotherapy. No prior radioisotope therapy with Strontium-89 or Samarium.
Patients with non-castrate levels of testosterone (Group B- androgen dependent disease) need to meet the following criteria:
A rising PSA after radical prostatectomy, radiotherapy or radiation implants with no evidence of metastatic disease on bone, CT scan or MRI scan.
PSA doubling time less than 12 months
Testosterone level \> 50 ng/ml
Age \> 18 years of age.
Karnofsky Performance Status \> 70%
Four weeks since major surgery.
Patients must have signed an informed consent document stating that they understand the investigational nature of the proposed treatment.
Required Initial Laboratory Data:
* WBC \> 3,000/µl
* ANC \> 1,500/µl
* Hemoglobin \> 9 g/dl
* Platelet count \> 100,000/µl
* Creatinine \< 1.5 x upper limits of normal
* Bilirubin within 2 x normal limits
* SGOT (AST) \< 2.5 x upper limits of normal
* SGPT (AST) \< 2.5 x upper limits of normal
* PSA \> 4.0 ng/ml (if no measurable disease for Group B) \> 4.0 ng/ml for Group A
* PT within normal limits(\*)
* PTT within normal limits(\*)
(\*)unless patients are already anti-coagulated for other reasons (i.e. atrial fibrillation, etc.)
Agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry and for the duration of study participation and for additional 1 months after finishing Phenoxodiol.
Able to swallow and retain oral medication
Life expectancy \>3 months
Patients may not be receiving any other investigational agents.
Patients may continue on a daily Multi-Vitamin and Calcium supplements but all other herbal, alternative and food supplements (i.e. PC-Spes, Saw Palmetto, St John Wort, etc.) must be discontinued before registration.
Bisphosphonate therapy for bone metastases is allowed; however, treatment must be initiated prior to the first dose of PXD. Prophylactic use of bisphosphonates in patients without bone disease, except for the treatment of osteoporosis, and initiation of bisphosphonates during study treatment is not permitted.
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.
Patients with 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) are excluded.
Patients with prior history of hemorrhagic or thrombotic cerebral vascular accident, deep venous thrombosis or pulmonary embolism within the past 6 months are excluded.
Patients with a "currently active" second malignancy other than non-melanoma skin cancers are not to be registered. Patients are not considered to have a "currently active" malignancy if they have completed therapy and are now considered (by their physician) to be at less than 30% risk for relapse.
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.
Because patients with immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy, HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with Phenoxodiol. Appropriate studies will be undertaken in patients receiving combination anti-retroviral therapy when indicated.
