PSMA1 and neoplasm: The in vivo treatment of PC3pip tumors showed that a combination of PDT and MMAE (PSMA-1-MMAE-Pc413 + PDT) significantly delayed tumor growth rates and increased animal survival times when compared to either chemotherapy alone (PSMA-1-MMAE-Pc413 with no PDT) or PDT alone (PSMA-1-Pc413 + PDT); see Figure 5 and Tables S2–S4.
