About this study

The primary objectives of this study are to:

  • Establish the phenotype and frequency of circulating immune cell compartments in patients undergoing treatment with Sipuleucel-T.
  • Determine the induction and the quality of prostate antigen-specific T cell immunity in patients undergoing treatment with Sipuleucel-T.
  • Correlate whole-blood RNA transcript-based signatures with clinical outcomes in patients treated with Sipuleucel-T.
  • Evaluate the cytokine and chemokine milieu in the peripheral blood pre- and post-treatment with Sipuleucel-T.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age > 18 years of age
  • Written informed consent obtained
  • Patients with castration-resistant prostate cancer who are initiating Sipuleucel-T as standard therapy
  • No prior systemic chemotherapy for metastatic prostate cancer
  • Hemoglobin > 9 mg/dl

Exclusion criteria

  • Patients unable to understand the research protocol and/or provide informed consent

Treatment and study plan

Primary outcomes

  1. Change in Regulatory T cells (Tregs)

    Time frame: baseline and 1 year

    Establish the phenotype and frequency of circulating immune cell compartments in patients undergoing treatment with Sipuleucel-T looking at the change in regulatory T cells at 1 year post treatment compared to at baseline

Secondary outcomes

  1. Change in Antigen Presenting Cells

    Time frame: baseline and 1 year

    Establish the phenotype and frequency of circulating immune cell compartments in patients undergoing treatment with Sipuleucel-T looking at the change in antigen presenting cells: DCs and B cells at 1 year post treatment compared to at baseline

  2. Change in Prostate Antigen-specific T Cell Immunity

    Time frame: baseline and one year

  3. Whole-blood RNA transcript-based signatures

    Time frame: baseline

    whole-blood RNA transcript-based signatures correlate with overall survival

  4. Whole-blood RNA transcript-based signatures

    Time frame: up to 1 year

    whole-blood RNA transcript-based signatures correlate with overall survival

  5. Change in cytokine milieu

    Time frame: baseline and 1 year

  6. Change in chemokine milieu

    Time frame: baseline and 1 year
