(Attachment 1) with a PSA> 5 ng/mL

7. On-going androgen deprivation with serum testosterone < 50 ng/dL (<
2.0nM)

8. Eastern Cooperative Oncology Group (ECOG) Performance Status of = 2
(Karnofsky Performance Status = 50%)

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

1. Active or uncontrolled autoimmune disease that may require corticosteroid
therapy

2. Serious or uncontrolled co-existent non-malignant disease, including active and
uncontrolled infection

3. Uncontrolled hypertension

4. Hemoglobin = 9.0 g/dL without growth factor or transfusion support

5. Abnormal liver function tests consisting of any of the following:
Serum bilirubin > 1.5 x ULN
ALT > 2.5 x ULN
AST > 2.5 x ULN

6. Serum creatinine > 2.0 x UNL or a calculated creatinine clearance < 50 mL/min

7. Serum potassium < 3.5 mmol/L

8. Clinically significant heart disease as evidenced by a myocardial infarction in the
past twelve months, severe or unstable angina, or New York Heart Association
(NYHA) Class III or IV heart disease. Patients with a history of atherosclerotic
vascular disease requiring coronary or peripheral artery bypass surgery may be
enrolled provided the surgery occurred at least two years prior to enrollment and
after consultation with a cardiologist to insure that the disease is stable

9. Abnormal electrocardiogram, including any finding which would interfere with
assessment of intervals (patients with long QT syndrome, bundle branch blocks
or hemiblocks are prohibited)

carcinomas of skin with a >30% probability of recurrence within 12 months

12. History of gastrointestinal disorders (medical disorders or extensive surgery)
which may interfere with the absorption of the study medication

13. Radiotherapy, chemotherapy or immunotherapy within 30 days of administration
of the Cycle 1 Day 1. Supportive care with glucocorticoid is not considered as an
immunotherapy; however, PSA progression must be documented under current
dose/regimen

14. Surgery or local prostatic intervention within 30 days of the first dose In
addition, any clinically relevant sequelae from the surgery must have resolved
prior to Cycle 1 Day 1

15. Current enrollment in an investigational drug or device study or participation in
such a study within 30 days of Cycle 1 Day 1

16. Initiate bisphosphonate therapy or adjust bisphosphonate dose/regimen within 30 days of Cycle 1 Day 1

17. Condition or situation which, in the investigator’s opinion, may put the patient at
significant risk, may confound the study results, or may interfere significantly
with patient’s participation in the study
