Overview
Brief Summary
This study is a prospective, single-center, open, single-arm, exploratory study to evaluate the safety and efficacy of 177Lu-EB-FAPI PRRT, and to explore 177Lu-EB-FAPI in patients with advanced pancreatic cancer and cholangiocarcinoma. Eligible patients with advanced pancreatic cancer or cholangiocarcinoma were screened and enrolled after signing the informed consent forms. In the first stage of the enrolled patients, the 177Lu-EB-FAPI treatment dose was determined using a 3 + 3 dose escalation mode. Patients enrolled in the second phase, divided into pancreatic cancer cohort and cholangiocarcinoma based on pathology, will receive the first phase determined dose of 177Lu-EB-FAPI every 4 weeks, and each patient will receive no more than 4 cycles. The aim of the study is to evaluate the safety and efficacy of the 177Lu-EB-FAPI treatment.
