Phase 1 Trial of Ipilimumab and GVAX in Patients With Metastatic Castration-resistant Prostate Cancer

Summary

Ipilimumab, an antibody that blocks cytotoxic T-lymphocyte antigen 4, and GVAX have demonstrated anti-tumor activity in prostate cancer. Pre-clinical studies with this combination have demonstrated potent synergy. The purpose of this study is to investigate, using a phase-I 3+3 dose escalation design followed by an expansion cohort, the safety and efficacy of combined treatment with GVAX and ipilimumab in castration-resistant metastatic prostate cancer (CRPC) patients.
