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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Gamma camera-based whole-body [99mTc]Tc(CO)3-(HE)3-Ec1 uptake value (%)	Whole-body [99mTc]Tc(CO)3-(HE)3-Ec1 uptake coinciding with normal organs and tissues will be assessed using gamma camera and calculated as percentage (%) of the injected dose of the radiopharmaceutical	24 hours
Primary	SPECT-based [99mTc]Tc(CO)3-(HE)3-Ec1 value in tumor lesions (counts)	[99mTc]Tc(CO)3-(HE)3-Ec1 uptake coinciding with tumor lesions will be assessed using single-photon emission computed tomography and measured in counts	6 hours
Primary	SPECT-based [99mTc]Tc(CO)3-(HE)3-Ec1 uptake value (counts)	Focal uptake of [99mTc]Tc(CO)3-(HE)3-Ec1 in the regions without pathological findings will be assessed with SPECT and measured in counts	6 hours
Primary	Tumor-to-background ratio (SPECT)	The SPECT-based tumor-to-background ratio will be calculated as follows: the value of [99mTc]Tc(CO)3-(HE)3-Ec1 uptake coinciding with tumor lesions (counts) will be divided by the value of [99mTc]Tc(CO)3-(HE)3-Ec1 uptake coinciding with the regions without pathological findings (counts)	6 hours
Secondary	Percent of cases with abnormal findings in physical examination, vital signs, and ECG associated with [99mTc]Tc(CO)3-(HE)3-Ec1 injections	The safety attributable to [99mTc]Tc(CO)3-(HE)3-Ec1 injections will be evaluated based on the assessments of physical examination, vital signs, and ECG (percent of cases with abnormal findings relative to baseline)	24 hours
