Eligibility Criteria
Inclusion Criteria:
- Previously randomized in Dendreon's P-11 study (NCT00779402) and received at least one infusion of sipuleucel-T
- Radiologic evidence of metastasis
- Castrate resistant prostate cancer. Subjects must have current or historical evidence of disease progression concomitant with surgical or medical castration, as demonstrated by PSA progression OR progression of measurable disease OR progression of non-measurable disease

- Adequate hematologic function
Exclusion Criteria:
- Eastern Cooperative Oncology Group (ECOG) performance status > 2
- Treatment with chemotherapy within 3 months prior to registration
- Treatment with systemic corticosteroids, abiraterone acetate, external beam radiation therapy, or any investigational product for prostate cancer within 28 days prior to registration
- Treatment with commercial sipuleucel-T (Provenge®)
- Current or imminent pathologic long-bone fracture or spinal cord compression
- Known malignancies other than prostate cancer likely to require treatment within 6 months following registration
- A requirement for systemic immunosuppressive therapy for any reason
- A history of allergic reactions attributed to compounds of similar chemical or biologic composition to sipuleucel-T or GM-CSF
- Any infection requiring antibiotic therapy or causing fever within 1 week prior to registration
- Any surgery requiring general anesthetic within 28 days prior to registration

5. Study Description
Brief Summary
Multicenter open label, uncontrolled study that enrolled men with metastatic castrate resistant prostate cancer previously treated with sipuleucel-T in the androgen dependent setting in the Dendreon P-11 study. The study was divided into Active and Long Term Follow-up (LTFU) Phases.
Detailed Description
Multicenter open label, uncontrolled study that enrolled men with metastatic castrate resistant prostate cancer previously treated with sipuleucel-T in the androgen dependent setting in the Dendreon P-11 study. The study was divided into Active and Long Term Follow-up (LTFU) Phases.
During the Active Phase eligible subjects received one infusion of sipuleucel-T every two weeks for for a total of three infusions. Subjects returned to the clinic for Week 6, Week 10, Month 6, and Month 12 visits. After the Month 12 visit, subjects were to enter the Long Term Follow-up Phase, in which they were contacted every 6 months via telephone.
Study Objectives:
Primary: Evaluate the immune response generated by sipuleucel-T.
Secondary: Evaluate the safety of sipuleucel-T and explore the correlation between sipuleucel-T immune response and overall survival.
