Co-injection of anti-HER2 antibody Trastuzumab does not increase efficacy of [177Lu]Lu-PSMA-617 therapy in an animal model of prostate cancer
One novel option for treating metastatic castration resistant prostate cancer is radionuclide therapy targeting prostate-specific membrane antigen (PSMA), e.g. [177Lu]Lu-PSMA-617. Overexpression of HER2 has been found in 80% of metastatic cases of prostate cancer. Previous research showed that HER2 is elevated post irradiation in PC-3 prostate cancer cells. Co-treating with anti-HER2 antibody Tras
