An Exploratory Evaluation of Technetium Tc 99m Tilmanocept by Intravenous (IV) Injection in Subjects With Liver Metastases From Colorectal Carcinoma Patients Using SPECT/CT Imaging Compared to Fluorodeoxyglucose (FDG) PET/CT Imaging.

Status: Terminated
Location: See location...
Intervention Type: Procedure, Drug
Study Type: Interventional
Study Phase: Phase 1

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.

Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: No

• 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 subjects must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-3;

• 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.

• If of childbearing potential, the subject has a negative urine pregnancy test within 48 hours before administration of Tc 99m Tilmanocept, has been surgically sterilized, or has been postmenopausal for at least 1 year

Time Frame
Start Date: July 26, 2017
Completion Date: September 24, 2018
Target number of participants: 3
Experimental: Cohort 1
Subjects will receive 50 µg tilmanocept radiolabeled with 2.0 millicuries (mCi) Tc99m through a single IV injection.
Experimental: Cohort 2
Subjects will receive 200 µg tilmanocept radiolabeled with 2.0 mCi Tc99m through a single IV injection.~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.
