Safety and Preliminary Efficacy of [177Lu]Lu-RTX-2358 Combined With Immune Checkpoint Inhibitors in Patients With FAP-positive Metastatic Non-Small Cell Lung Cancer

Summary

This is a prospective, single-center, open-label investigator-initiated study designed to evaluate the safety, tolerability, radiation dosimetry, biodistribution, and preliminary antitumor activity of \[177Lu\]Lu-RTX-2358 in combination with immune checkpoint inhibitors (ICIs) in patients with fibroblast activation protein (FAP)-positive metastatic non-small cell lung cancer (NSCLC). Eligible participants will receive one or two cycles of \[177Lu\]Lu-RTX-2358 followed by standard PD-1 inhibitor therapy. Safety, tumor response, biodistribution, radiation dosimetry, and survival outcomes will be evaluated throughout treatment and follow-up.
