Clinical Trial Summary

Estimation of the concordance of Tc 99m localization in liver metastases from colorectal carcinoma using SPECT/CT imaging and abdominal FDG (PET)/CT imaging per subject.

Description:

This is a prospective, open-label, single-center, comparator study of IV injected Tc 99m Tilmanocept in the localization and detection of liver metastases in subjects with confirmed colorectal carcinoma (CRC). The study will be divided into two cohorts.

If it was determined that additional enrollment would not provide meaningful data, for example no metastatic liver lesions were visualized by Tc 99m tilmanocept for any of the subjects in the cohort, enrollment into Cohort 2 would begin and 3 subjects would be enrolled followed by a review of the imaging and safety data.

This study is designed to evaluate the safety and tolerability of Tc 99m tilmanocept administered intravenously. SPECT/CT imaging of the subject's abdominal cavity will be reviewed to establish concordance with FDG PET imaging.

Eligibility

Inclusion Criteria:

• The subject has provided written informed consent with Health Information Portability and Accountability Act (HIPAA) authorization before the initiation of any study-related procedures.

• Subjects must be =18 years old;

• The subject must have a diagnosis of adenocarcinoma of the colon and/or rectum with FDG PET/CT confirmed metastases to the liver;

• The subject must be at least 4 weeks past any major intraabdominal surgery, including surgery to the liver;

• Subjects with prior malignancies other than colon and/or rectum cancer are allowed, provided they have been treated with curative intent, and have no evidence of recurrence of that malignancy;

• Each subject must have no more than 10 qualifying liver lesions that have been clinically confirmed metastatic adenocarcinoma of the colon by FDG PET/CT imaging.

Primary	Visualization of Lesions by FDG PET/CT Imaging and by Tc 99m Tilmanocept SPECT/CT Imaging.	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.	Within 7 days after Tc 99m tilmanocept administration
