When compared with other 177Lu-labeled PSMA ligands, 177Lu-rhPSMA-10.1 achieved significantly greater tumor growth suppression than did 177Lu-PSMA-I&T, consistent with our biodistribution data showing higher uptake and retention in tumors for 177Lu-rhPSMA-10.1 than for 177Lu-PSMA-I&T. Here, FOLH1 is linked to neoplasm.
