An Imaging Agent (I-124 M5A) in Detecting CEA-Positive Liver Metastases in Patients With Colorectal Cancer
Pilot Study: Detection of Colorectal Metastatic Liver Disease Preoperatively Using 124I-Labeled M5A Monoclonal Antibody to Carcinoembryonic Antigen (CEA)
Study Overview

Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVES:
I. To determine the ability of iodine I 124 monoclonal antibody M5A (124I-labeled M5A monoclonal antibody [MAb]) to localize to CEA positive gastrointestinal (GI) metastases primarily focused on the liver.
SECONDARY OBJECTIVES:
I. To determine the safety and pharmacokinetics of administration of 124I-labeled M5A MAb.
II. To correlate the radiographic positron emission tomography (PET) images to the liver metastases pathology.
III. To assess if the I-124 imaging agent detected additional liver and additional extra-hepatic liver lesions not appreciated on standard imaging scans.
OUTLINE:
Patients receive iodine I 124 monoclonal antibody M5A intravenously (IV) on day 0 and undergo PET scan on days 2 and 6.
After completion of study, patients are followed up periodically for 1 year.

Description
Inclusion Criteria:
- Patients must have histologically confirmed metastatic colorectal cancer with liver metastases. NOTE: We are not requiring proof of CEA positive disease because > 95% of colorectal cancers are CEA positive
- The effects of 124I-M5A on the developing fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for six months following duration of study participation. Should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately
- Patients must have at least 2 known sites of metastatic liver disease. Patients should have at least one resectable liver metastasis as assessed by hepatobiliary surgical oncology
- The results of the imaging scans that are performed as part of the standard work up should be available and should have been done within 2 months prior to study entry
- All subjects must have the ability to understand and the willingness to sign a written informed consent
- Prior therapy (chemotherapy, immunotherapy, radiotherapy) must be completed at least 2 weeks prior to infusion of radiolabeled antibody
Exclusion Criteria:
- Patients should not have any uncontrolled illness including ongoing or active infection
- Patients who have allergy to iodine or iodine contrast agents are not eligible for this protocol
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to 124I-M5A
- Patients must not have received prior chemotherapy or radiation for >= 2 weeks before study enrollment
- Pregnant women are excluded from this study because 124I-M5A is an agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with 124I-M5A, breastfeeding should be discontinued if the mother is treated with 124I-M5A
- Patients with single (= 1) liver metastasis are not eligible for this protocol
- Any patient who has had exposure to mouse, chimeric (human/mouse) or humanized immunoglobulin and has antibody to the M5A
- Subjects, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study
