  • Capacity of T cells to proliferate in response to antigen stimulation, assessed with a tritiated thymidine incorporation assay and an IFN-gamma ELISPOT assay [ Time Frame: Up to 6 months ] [ Designated as safety issue: No ]
    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.
  • Quantification of lymphocyte subsets and NK cells [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]
    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.
  • Change in the genetics of immune effectors, measured with RNA from monocytic and lymphocytic cells [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]
    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.
  • Change in antigen-specific humoral response measured via ELISA [ Time Frame: Baseline up to 6 months ] [ Designated as safety issue: No ]
    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.

  • Adverse event rates assessed using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4 [ Time Frame: Up to 6 months ] [ Designated as safety issue: Yes ]
    The Clopper-Pearson one-sided upper 95% confidence limit will be provided. Associations between baseline characteristics and presence of an adverse event (AE) will be considered using the Wilcoxon Rank Sum test (or Cochran-Armitage test for trend) and Fisher's Exact test respectively. Bar charts, scatterplots and other descriptive and graphical methods will also be utilized.
  • Change in PSA [ Time Frame: Baseline up to 6 months ] [ Designated as safety issue: No ]
  • Overall survival [ Time Frame: Up to 6 months ] [ Designated as safety issue: No ]
    Will be depicted using Kaplan Meier methods.

Radiation Therapy in Treating Patients With Metastatic Hormone-Resistant Prostate Cancer Receiving Sipuleucel-T
Pilot: Impact of High-Dose, Single Fraction Radiation on Immunogenicity of Sipuleucel-T in Metastatic Castration Recurrent Prostate Cancer Patients

This pilot clinical trial studies the impact of radiation therapy on the immunogenicity of Sipuleucel-T. Patients with castration recurrent prostate cancer who are eligible for treatment with Sipuleucel-T and who have bone metastases are eligible.

PRIMARY OBJECTIVES:

I. To assess whether radiation therapy (RT) increases the immunogenic potential or sipuleucel-T in patients with castration recurrent prostate cancer.

II. To assess systemic changes to the immune system and genetic changes to immune cells in patients treated by the combination of RT and sipuleucel-T.

III. To assess the induction of antigen-specific immune responses to prostatic acid phosphatase (PAP), cancer/testis antigen 1B (NY-ESO-1) and antigens that have proven to be released by radiation (such as, heat shock protein 90 [HSP-90], calreticulin, etc.).

SECONDARY OBJECTIVES:

I. To assess adverse event rates in patients receiving the high-dose radiation and sipuleucel-T therapy.

II. Prostate-specific antigen (PSA) changes will be assessed. III. Overall and cancer specific survival will be assessed.

OUTLINE:

Patients undergo single-fraction radiation therapy to at least 1 bone lesion 2 days after the first sipuleucel-T dose.

After completion of study treatment, patients are followed up at 3 and 6 months.
