Summary

This is a multicentered, open label, randomized phase II trial of PROSTVAC or ipilimumab or the combination of PROSTVAC and ipilimumab as neoadjuvant therapy in patients with localized prostate cancer. Eligible patients will be randomized to PROSTVAC monotherapy (Arm A), ipilimumab monotherapy (Arm B), or combination therapy with both PROSTVAC and ipilimumab (Arm C), prior to RP. In arms A and C, PROSTVAC-V will be administered subcutaneously as the primary vaccine on Day 1, which will be followed 2 weeks later with a series of 2 PROSTVAC-F subcutaneous administrations, given 3 weeks apart. In arms B and C, ipilimumab will be administered twice, at a dose of 3mg/kg, 3 weeks apart. In the combination arm, ipilimumab administration will coincide with the PROSTVAC-F administration. In arm B, ipilimumab will begin on Day 1. In all three arms, radical prostatectomy (RP) will occur 21 days, or three weeks, following final treatment administration of PROSTVAC or ipilimumab. No further therapy will be administered on study following RP.

Conditions

  • Prostatic Neoplasms

Interventions

BIOLOGICAL

PROSTVAC V/F

PROSTVAC-V/F is a prostate-specific antigen(PSA)-based immunization strategy. It is intended to generate immune responses to prostate specific antigens and prostate cancer cells. It uses poxviral vectors to introduce modified PSA to the patient in an immunogenic manner to break self-tolerance, and thereby induce immune responses directed against prostate cancer cells.
