Summary
Brief summary (as posted)
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 investigate the efficacy and safety of 177Lu-DOTA-EB-FAPI in patients with various solid tumors who had failed standard therapies.

Primary outcomes (1)
- measure
- Radiological response (according to RECIST criteria)
- timeFrame
- 6 weeks, 12 weeks, 18 weeks, or up to 6 months
- description
- RECIST objective response after completion of radioligand therapy, which was defined by response category between baseline and restaging after RLT. Disease control after RLT was defined as either complete response (CR), partial response (PR), or stable disease (SD). Disease control rate (DCR) was reported as the proportion of patients with disease control after RLT.
