Phase 1
Completed
Conditions
Hodgkin Lymphoma, Adult
Non-Hodgkin Lymphoma, Adult
Interventions
Diagnostic Test: SPECT with 99mTc-1-thio-D-glucose
Registration Number
NCT04292626
Lead Sponsor
Tomsk National Research Medical Center of the Russian Academy of Sciences
Brief Summary

The study should evaluate the biological distribution of 99mTc-1-thio-D-glucose in patients with Hodgkin Lymphoma and Non Hodgkin Lymphoma.

The primary objective are:

1. To assess the distribution of 99mTc-1-thio-D-glucose in normal tissues and tumors at different time intervals.

2. To evaluate dosimetry of 99mTc-1-thio-D-glucose.

3. To study the safety and tolerability of the drug 99mTc-1-thio-D-glucose after a single injection in a diagnostic dosage.

The secondary objective are:

1. To compare the obtained 99mTc-1-thio-D-glucose SPECT imaging results with the data of CT imaging and/or 18F-FDG positron emission tomography (PET) and immunohistochemical (IHC) studies in Lymphoma patients.

Detailed Description

The overall goal is to study the effectiveness of SPECT imaging Hodgkin Lymphoma and Non Hodgkin Lymphoma Using technetium-99m labeled 1-thio-D-glucose.

Phase I of the study:

Biodistribution of 99mTc-1-thio-D-glucose in patients with Hodgkin Lymphoma and Non Hodgkin Lymphoma.

The main objectives of the study:

1. To evaluate the distribution of 99mTc-1-thio-D-glucose in normal tissues and tumors in patients with Lymphoma at different time intervals.

2. To evaluate dosimetry of 99mTc-1-thio-D-glucose 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-1-thio-D-glucose 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 Lymphoma by SPECT using 99mTc-1-thio-D-glucose with data obtained by CT and/or positron emission tomography (PET) 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.

Primary Outcome Measures
NameTimeMethod
SPECT-based 99mTc-1-thio-D-glucose uptake value (counts)6 hours

Focal uptake of 99mTc-1-thio-D-glucose in the regions without pathological findings will be assessed with SPECT and measured in counts

Tumor-to-background ratio (SPECT)6 hours

The SPECT-based tumor-to-background ratio will be calculated as follows: the value of 99mTc-1-thio-D-glucose uptake coinciding with tumor lesions (counts) will be divided by the value of 99mTc-1-thio-D-glucose uptake coinciding with the regions without pathological findings (counts)

Gamma camera-based whole-body 99mTc-1-thio-D-glucose uptake value (percent)24 hours

Whole-body 99mTc-1-thio-D-glucose uptake coinciding with normal organs and tissues will be assessed using gamma camera and calculated as percentage (percent) of the injected dose of the radiopharmaceutical

SPECT-based 99mTc-1-thio-D-glucose value in tumor lesions (counts)6 hours

99mTc-1-thio-D-glucose uptake coinciding with tumor lesions will be assessed using single-photon emission computed tomography and measured in counts

Secondary Outcome Measures
NameTimeMethod
Safety attributable to 99mTc-1-thio-D-glucose injections24 hours

Percent of participants with treatment-related adverse events requiring drug treatment will be used to assess the safety attributable to 99mTc-1-thio-D-glucose injections.

Safety attributable to 99mTc-1-thio-D-glucose injections (physical findings)24 hours

The safety attributable to 99mTc-1-thio-D-glucose injections will be evaluated based on the assessments of physical examination, vital signs, and ECG (percent of cases with abnormal findings relative to baseline)

Safety attributable to 99mTc-1-thio-D-glucose injections (laboratory tests)24 hours

The safety attributable to 99mTc-1-thio-D-glucose injections will be evaluated based on the blood and urine laboratory tests (percent of cases with abnormal findings relative to baseline)

Safety attributable to 99mTc-1-thio-D-glucose injections (incidence and severity of adverse events)24 hours

The safety attributable to 99mTc-1-thio-D-glucose injections will be evaluated based on the rate of adverse events (percent)
