A Study of 99mTc-3PRGD2 Injection in Healthy Volunteers
Phase I Open Label Trial of Pharmacokinetics and Safety of 99mTc Niacinamide Polyethylene Glycol Bicyclic RGD Peptide (99mTc-3PRGD2) Injection in Healthy Volunteers
The study drug 99mTc-3PRGD2 of this study is a new radioactive diagnostic preparation for clinical use as a nuclear medicine molecular probe for tumor SPECT/CT imaging.
After 99mTc-3PRGD2 is injected into the body, it is specifically taken up by integrin receptor-positive tumor tissue, and tumor tissue is developed by SPECT/CT, which can be used for molecular imaging diagnosis and individualized treatment of common tumors.
The primary objectives of this study is to examine the pharmacokinetics the safety of 99mTc-3PRGD2 injection in healthy volunteers, as well as the biodistribution in the human body and to estimate the dose of internal radiation absorbed. This study provides the basis for the design of phase II clinical research programs.

Detailed Description
To a large extent, cancer treatment outcomes depend on the accurate diagnosis and staging of the disease. An important basis for early diagnosis of malignant tumors is medical imaging. Single-Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) are most well-developed nuclear medicine procedures based on the measurement of radiolabeled tracer molecules.
These radiotracers allow biologic processes to be measured and whole body images to be obtained, which will demonstrate exact locations of radiotracer accumulation. Functional imagings of SPECT and PET provide specific information which is not available from standard medical imaging modalities such as ultrasound, X-ray, computerized tomography (CT) or magnetic resonance imaging (MRI).
The test drug in this study is a new radioactive diagnostic preparation, consisting of radiochemical (Sodium Pertecheetate [99mTc] Injection) and a kit (including Three core ligands, HYNIC-3PRGD2, Tricine, TPPTS). Before administration, 99mTc:HYNIC-3PRGD2:Tricine:TPPTS (1:1:1:1) chelate compound (99mTc-3PRGD2) will be prepared as per standard opration presedure, which will be used as a molecular probe for SPECT/CT imaging.
The core ligand HYNIC-3PRGD2 is a novel RGD dimer that specifically binds to the integrin αvβ3 receptor with high selectivity and affinity. Integrin αvβ3 is highly expressed in tumor neovascularization. After injection, 99mTc-3PRGD2 will be specifically taken up by the integrin receptor-positive tumor tissue, then be imaged by SPECT/CT. The product can be used for molecular imaging diagnosis and individualized treatment for common tumors such as lung cancer and breast cancer are performed.
The primary objectives of this study is to examine the pharmacokinetics the safety of 99mTc-3PRGD2 injection in healthy volunteers, as well as the biodistribution in the human body and to estimate the dose of internal radiation absorbed. This study provides the basis for the design of phase II clinical research programs.
