Trial Outcomes & Findings for An Evaluation of Tilmanocept by IV Injection Using SPECT/CT vs PET Imaging in Subjects With Liver Metastases. (NCT NCT03029988)

NCT ID: NCT03029988

Last Updated: 2020-09-10

Results Overview

The primary objectives of this study were to estimate the concordance of Tc 99m tilmanocept localization in liver metastases from colorectal carcinoma (CRC) using single photon emission computed tomography / computed tomography (SPECT/CT) imaging and abdominal fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) imaging per subject and to evaluate the safety including monitoring the incidence of adverse events and changes over time in laboratory tests, vital signs, and physical examination findings.

Measure
Cohort 1 - FDG PET CT
n=3 Participants
At screening, an FDG PET/CT scan was done in accordance with standard procedures
Cohort 1 - Tilmanocept SPECT/CT
n=3 Participants
Subjects received 50 µg tilmanocept radiolabeled with 2.0 mCi Tc 99m through a single IV injection. SPECT/CT imaging of the abdominal region occurred 4-6 hours post-injection. Note: The liver lesion visualized by FDG PET/CT was excised prior to SPECT/CT imaging.
