Brief Summary

Background: \- Few studies or literature are available about the long-term safety of repeated peptide vaccinations in people over a period of time. Long-term vaccination may be needed to control tumors. Researchers gave a group of men a series of vaccine injections over 2 years. Now they want to give those same men the new version of the vaccine. They want to see if it produces different types of immune responses and also ensure that repeated vaccinations are safe. Objectives: \- To find out the long-term safety of repeated T-cell receptor alternate reading frame protein (TARP) peptide vaccinations. Eligibility: \- Men who took part in National Cancer Institute (NCI) protocol 09-C-0139. Design:

  • Participants will be screened with blood tests, scans, physical exam, medical history, and an evaluation of how well they perform everyday activities.
  • Participants will have apheresis. Blood will be removed with a needle from one arm. A machine will separate the white blood cells. The blood, minus the white cells, will be returned through a needle in the other arm.
  • Participants will have 14 visits. At each visit, they will have a physical exam and blood tests. They will discuss any side effects.
  • Participants will get vaccine injections at weeks 3, 6, 9, 12, 15, and 24. The vaccine will be made from the participants own cells.
  • Participants will get a Vaccine Report Card to complete after receiving vaccine.
  • The study lasts 96 weeks.

Outcome Measures

Primary Outcomes (1)

  • Number of Grade 3 Adverse Events (AEs) Probably Related to the Vaccine Treatment

    The number of Grade 3 adverse events probably related to the vaccine treatment. Adverse events were measured using the Common Terminology Criteria for Adverse Events (CTCAE v.4.0). Grade 3 is severe.

    Up to 30 days after week 24 vaccination

Secondary Outcomes (4)

  • Change in Slope Log PSA From Pre-study Baseline (-12 Months to Entry on the Current Study) to the Change in Slope Log PSA at Weeks 3-24 and 3-48 Post Multi-Epitope (ME) T-cell Receptor Alternate Reading Frame Protein (TARP) Vaccination

    Weeks 3-24 minus baseline, and Weeks 3-48 minus baseline

  • Change in Slope Log Prostate Specific-antigen (PSA) Versus the Same Change in Slope Log PSA Parameters Following 1st Generation T-cell Receptor Alternate Reading Frame Protein (TARP) Vaccination on Protocol 09-C-0139

    Weeks 3-24 minus baseline, and Weeks 3-48 minus baseline

  • Number of Participants With Reactivity to WT27-35 and EE29-37-9V T-cell Receptor Alternate Reading Frame Protein (TARP) Peptides

    Week 24 and Week 48 following immunization with the 2nd generation Multi-Epitope (ME) TARP

  • Number of Participants Positive for T-cell Receptor Alternate Reading Frame Protein (TARP) WT27-35 and EE29-37-9V Peptide Reactivity to That of the 1st Generation TARP Vaccine in the Same Individuals on Protocol 09-C-0139 (NCT00972309) and 15-C0076

    Week 24 and 48 following Multi-Epitope (ME) TARP vaccination

Other Outcomes (1)

  • Number of Participants With Serious and/or Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v.0)

    Date treatment consent signed to date off study, approximately 82 months and 6 days
