Phase II Study to Assess the Activity of Nexrutine® in Prostate Cancer Patients Undergoing Surgery or Radiation Therapy

Inclusion Criteria:

1. Have a histologic diagnosis of prostate cancer (in more than 1 core) with one of the
following:

- Gleason > 6,

- Unilateral Gleason 6 in ≥ 3 cores,

- bilateral Gleason 6,

2. Age ≥18 years.

3. Has an ECOG Performance Status 0-2 or Karnofsky 60-100.

4. Has the following laboratory values at study entry: absolute neutrophil count (ANC) ≥
1,500 cells/μL; platelet count ≥ 100,000 cells/μL; hemoglobin ≥ 9 g/dL; total serum
bilirubin ≤ 1.5 x institutional upper limit of normal (ULN); ALT and AST ≤ 1.5 x
institutional ULN if alkaline phosphatase is ≤ULN creatinine and BUN ≤ 1.5 x
institutional upper limit of normal (ULN)

5. Signed informed consent

6. No new, undiagnosed bone pain or has a negative bone scan. (within 2 months of
consent) If there is no bone pain, then a bone scan is not required.

Exclusion Criteria:

3. Has received prior immunotherapy.

4. Has been previously treated with Strontium, Samarium, other systemic radioisotopes or

7. Is receiving any other investigational agents for cancer.

8. Has a history of other malignancy within the last 5 years, which could affect the

12. Clinical stage T3 or T4 and PSA >10 ng/ml and Gleason > 8.

13. Patient is to receive adjuvant androgen ablation with the radiation.

14. EKG which shows a baseline QTc > 450 msec or ischemic changes. For ischemic changes,
patient will be eligible if evaluated and cleared by internal medicine.

15. Previous history of drug-induced QTc prolongation and/or concurrent treatment with
medications that are known to produce or are suspected of QT prolongation.
