Safety & Immunogenicity of JNJ-64041809, a Live Attenuated Double-deleted Listeria Immunotherapy, in Participants With Metastatic Castration-resistant Prostate Cancer

Summary

The purpose of this study is to find and evaluate the recommended Phase 2 dose (RP2D) of JNJ-64041809, a live attenuated double deleted (LADD) Listeria monocytogenes (bacteria in which two virulence genes, which encode molecules that help cause disease, have been removed) when administered intravenously to participants with metastatic castration-resistant prostate cancer (mCRPC).
