68Ga-CTR-FAPI PET-CT-guided Precision Surgery for Newly Diagnosed Medullary Thyroid Carcinoma: A Multicenter, Open-labeled, Randomized Controlled Phase 3 Trial

Description:

This is a multicenter, randomized, open-label, non-inferiority Phase III clinical trial, aims to compare 68Ga-CTR-FAPI PET-CT-guided surgery to investigator-chosen surgical approaches to evaluate its efficacy in treating newly diagnosed medullary thyroid carcinoma. This study plans to enroll 150 newly diagnosed MTC patients, who will be randomly assigned in a 2:1 ratio to the experimental group (surgery based on 68Ga-CTR-FAPI PET-CT findings) and the control group (surgery based on the investigator's choice). The primary endpoint is the biochemical cure rate, with secondary endpoints including the biochemical cure rate in the R0 resection subgroup, the unnecessary dissection rate in the biochemical-cured subgroup, 3-year recurrence-free survival, the rate of change in surgical extent, and diagnostic accuracy.
