Clinical Trial Summary

The study should evaluate the biological distribution of [99mTc]Tc(CO)3-(HE)3-Ec1 in patients with solid tumor The primary objective are: 1. To assess the distribution of [99mTc]Tc(CO)3-(HE)3-Ec1 in normal tissues and tumors at different time intervals. 2. To evaluate dosimetry of [99mTc]Tc(CO)3-(HE)3-Ec1 . 3. To study the safety and tolerability of the drug [99mTc]Tc(CO)3-(HE)3-Ec1 after a single injection in a diagnostic dosage. The secondary objective are: 1. To compare the obtained [99mTc]Tc(CO)3-(HE)3-Ec1 SPECT imaging results with the data of CT and/or MRI and/or ultrasound examination and immunohistochemical (IHC) studies in solid tumor patients.


Clinical Trial Description

The overall goal is to study the effectiveness of SPECT imaging solid tumor patients using [99mTc]Tc(CO)3-(HE)3-Ec1. Phase I of the study: Biodistribution of [99mTc]Tc(CO)3-(HE)3-Ec1 in patients with solid tumor. The main objectives of the study: 1. To evaluate the distribution of [99mTc]Tc(CO)3-(HE)3-Ec1 in normal tissues and tumors in patients with solid tumor at different time intervals. 2. To evaluate dosimetry of [99mTc]Tc(CO)3-(HE)3-Ec1 based on the pharmacokinetic parameters of the drug after a single intravenous administration. 3. To study the safety of use and tolerability of the drug [99mTc]Tc(CO)3-(HE)3-Ec1 after a single intravenous administration in a diagnostic dosage. Additional research tasks: 1. To conduct a comparative analysis of the diagnostic information obtained in the visualization of solid tumor by SPECT using [99mTc]Tc(CO)3-(HE)3-Ec1 with data obtained by CT and/or MRI and/or ultrasound examination and immunohistochemical (IHC) research of postoperative material. Methodology: Open-label, exploratory, single centre study. The subjects will receive a single injection of the labeled tracer. ;
