Clinical Trial Summary

Increased fibroblast activation protein expression is positively correlated with the aggressiveness of cancer. Radiolabeled fibroblast activation protein inhibitor therapy, also known as radioligand therapy has become a novel treatment for patients with refractory cancer and disease progression after multiple-lines treatment. However, a major problem in the therapeutic use of 177Lu-DOTA-FAPI has been its short half-life and fast rate of clearance. This study was designed to evaluate the safety and tolerabilityof a long-lasting radiolabeled fibroblast activation protein inhibitor 177Lu-DOTA-EB-FAPI in patients with various refractory solid tumors.


Clinical Trial Description

This IIT study will include a maximum of 20 subjects with progressive cancer after multiple-line treatment, with an increased radiotracer uptake in tumors on 68Ga-FAPI-46 PET/CT. The fixed dose of 177Lu-DOTA-EB-FAPI is 3.7GBq (100 mCi). Treatment is planned for up to 2 cycles, and the time interval between cycles is 6 weeks. The primary endpoint assessed the safety and maximum tolerated dose of 177Lu-DOTA-EB-FAPI used for radioligand therapy in patients with various advanced tumors. Secondary endpoints included dosimetry and determination of the preliminary treatment efficacy of 177Lu-DOTA-EB-FAPI. ;
