Inclusion Criteria:

Signed and dated written Ethics Committee approved informed consent
Men aged 21 to 85 years with a histologic diagnosis of prostate cancer with a biochemical relapse following definitive local therapy (RP or radiation therapy)

No prior cytotoxic chemotherapy for the current cancer
Normal electrocardiogram (ECG) or ECG with no clinically significant findings as determined by the Principal Investigator
Presence of biochemically relapsed prostate cancer defined as either: 1) PSA > 2 ng/mL 1 year following initial definitive treatment for prostate cancer: or, 2) PSA doubling time (greater than 0.2 ng/mL) < 12 months; or, 3) PSA velocity > 2 ng/mL/year at any time following radical prostatectomy or radiation therapy.
Positive expression of HAAH in either archived tumor tissue (if available) or fresh serum

Any illness or condition that in the opinion of the Investigator may affect the safety of the patient or the evaluation of any study endpoint

Screening blood counts of the following:

Hematopoietic:

Absolute neutrophil count < 1500/μL, Platelets < 100,000/μL, Hemoglobin < 9 g/dL;

Liver/Metabolic:

Renal:

Creatinine clearance < 50 mL/min as predicted by the Cockcroft-Gault formula
