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 FDG PET/CT Imaging. (NCT03029988)

National Cancer Institute (NCI)
National Institutes of Health (NIH)
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.
  • Drug: Tilmanocept (Technetium Tc 99m tilmanocept Injection)
    Drug: Technetium Tc 99m tilmanocept
    • Lymphoseek
  • Procedure: SPECT/CT Imaging
    4-6 hours post-injection SPECT/CT will be obtained in the abdominal region.
    Ages eligible for Study
    18 Years and older
    Genders eligible for Study
    Accepts Healthy Volunteers
    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 subjects must have an 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
    Exclusion Criteria:
    • The subject is pregnant or lactating.
    • The subject has undergone any liver surgery, exclusive of a biopsy.
    • The subject has known sensitivity to dextran.
    • The subject has had preoperative chemotherapy, immunotherapy, or radiation therapy within the 10 days prior to Tc 99m Tilmanocept administration
    • Before the administration of Tc 99m Tilmanocept, has received any radiopharmaceutical within 7 radioactive half-lives of that radiopharmaceutical
    • Has received an investigational product within the 30 days prior to Tc 99m Tilmanocept administration
    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 CRC. The study will be divided into two cohorts.

    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.
