We have recently reported that a radioiodinated, DTPA-appended peptide, designated IMP-R1, is a residualizing iodine label that overcomes many of the limitations that have impeded the development of residualizing iodine for clinical use. In this study the potential of131I-IMP-R1-RS7, an internalizing anti-EGP-1 monoclonal antibody, was evaluated by performing preclinical therapy studies in nude mice bearing Calu-3 human non-small cell carcinoma of the lung xenografis. Elimination of 6 of 9 established tumors (mean tumor volume=0.3 cm3) was observed using a single dose of 350 μCi/mouse of131I-IMP-R1-RS7, with all animals tolerating the dose. At the same dose and specific activity of131I-RS7, labeled using the conventional chloramine-T method, there were four deaths, and one complete remission in nine treated mice. At the maximum tolerated dose of conventionally131I-labeled RS7, 275 μCi, mean stable disease for ∼5 weeks was observed, with no complete responses. Specificity of the therapeutic effect was shown in an isotype-matched control experiment, where131I-IMP-R1-RS7 was markedly more effective than the131I-IMP-R1-labeled control antibody. These studies demonstrate that131I-IMP-R1-RS7 provides a therapeutic advantage in comparison to conventional131I-labeled RS7, as predicted by the increased tumor accretion observed previously in targeting studies. A direct comparison of the maximum tolerated doses of131I-IMP-R1-RS7 (350 μCi) and90Y-DOTA-RS7 (105 μCi) was performed in this tumor model using large established tumors (mean tumor volume=0.85 cm3). Anti-tumor efficacy and toxicity of the two treatments were comparable.
