  9. Platelet count ≥ 150,000 x 10^9/L
  10. Total bilirubin ≤ 1.5x upper limit of normal range, excluding Gilbert syndrome
  11. Serum AST ≤ 1.5 x upper limit of normal range

  16. Ability to understand and willingness to sign an informed consent form prior to initiation of any study procedures.
  17. Age ≥ 18 years

Exclusion Criteria:

  1. Prior radionuclide therapy for CRPC

  3. Antiandrogen therapy within 4 weeks of enrollment. However, patients with primary failure of secondary anti-androgen therapy OR symptomatic progression, objective progression and/or biochemical evidence of rising PSA less than 4 weeks after discontinuation of anti-androgen therapy will not have anti-androgen withdrawal responses and will not be excluded.
  4. Preexisting peripheral neuropathy grade 2 or higher.
  5. Other serious medical condition as judged by the investigator.
  6. Active second malignancy that requires therapy.
  7. Known brain or leptomeningeal metastases
  8. Concurrent enrollment in any other investigational anticancer therapy
  9. Treatment with any myelosuppressive agent within 30 days of enrollment
  10. Presence of bulky visceral metastases, defined as any of the following:
  11. ≥ 4 lung lesions (at least 1cm each in size in the longest diameter) or pulmonary lymphangitic metastasis
  12. Liver metastases with sum of lesion diameters totaling ≥ 5cm
  13. Evidence of neuroendocrine or small cell differentiation on prior biopsy
  14. History of severe hypersensitivity reactions to docetaxel or to drugs formulated with polysorbate 80
