Study Summary

Pilot Immunotherapy Study of Combination Prostate Specific Membrane Antigen (PSMA) and T-cell receptor γ alternate reading frame protein (TARP) Peptide With Poly IC-LC Adjuvant in Human Leukocyte Antigens (HLA)-A2 (+) Patients With Elevated prostatic specific antigen (PSA) After Initial Definitive Treatment The purpose of the study is to see if the PSMA/TARP proteins in the vaccine, along with the Hiltonol, can arouse and train the immune system to kill the prostate cancer cells. Prostate cancer is the most common cancer and is the second leading cause of cancer deaths in U.S. males. It is curable when it is confined to the prostate (kept from spreading) using surgery or radiation treatments. In some patients the cancer can come back after these treatments. Treatment options for prostate cancer that comes back include procedures or medications which may have significant risks and side effects. Another plan is being looked at that uses the body's immune system to attack prostate cancer cells. A vaccine has been developed that has proteins found in prostate cancer cells. One of the proteins is called PSMA and the other is called TARP. In addition to these proteins, another substance called Poly IC-LC (Hiltonol) will be added to the vaccine to boost its ability to start the immune system.

Primary Outcome

Number of participants with related Grade 3 or higher adverse events. Establish the safety and toxicity of varying doses of polypeptide vaccines PSMA and TARP administered with a fixed dose of Poly IC-LC as an adjuvant.

Interventions
