99mTc-3PRGD2 SPECT/CT for Integrin Imaging of Lung Cancer

Overview

This is a prospective, multicenter, self-controlled phase 3 clinical trial designed to evaluate the safety and efficacy of an integrin αVβ3-targeted imaging, 99mTc-3PRGD2 SPECT/CT, for diagnosis of lung cancer and mapping the lymph node metastases. The pathological results will be considered as the gold standard and the conventional metabolic imaging by 18F-FDG PET/CT will be used for a head-to-head comparison. The primary objective of this study is to evaluate the efficacy of 99mTc-3PRGD2 SPECT/CT in mapping of lymph node metastasis according to the nodal mapping system released by the International Association for the Study of Lung Cancer in 2009 (IASLC-2009). The secondary objectives include evaluation of 99mTc-3PRGD2 SPECT/CT in detection of lung cancer and the safety of 99mTc-3PRGD2 injection in human beings.
