Current Primary Outcome Measures (submitted: November 14, 2014)

• Efficacy of each modality in locating cancer in each of four regions (primary, hepatic, extra-hepatic abdominal, and extra-abdominal) using lesion analysis [ Time Frame: Up to day 2 ]
  For lesion analysis, the efficacy of each modality will be evaluated where a successful outcome will be defined as the ability of at least one known tumor identified by conventional imaging modalities to be imaged using the M5A antibody. Using the standard statistical formulas, the number of true positives, false positives, true negatives, and false negatives, as well as the sensitivity and corresponding 95% confidence interval will be estimated using the method of Lee and Dubin or Rao and Scott, which accounts for the correlation between lesions within in same subject.
• Efficacy of each modality in locating cancer in each of four regions (primary, hepatic, extra-hepatic abdominal, and extra-abdominal) using region analysis [ Time Frame: Up to day 2 ]
  For region analysis, a successful outcome will be defined as the identification of suspicious tissue within a region. Using the standard statistical formulas, the number of true positives, false positives, true negatives, and false negatives, as well as the sensitivity and corresponding 95% confidence interval will be estimated using the method of Lee and Dubin or Rao and Scott, which accounts for the correlation between lesions within in same subject.
• Pharmacokinetic parameters of copper Cu 64 anti-CEA monoclonal antibody M5A [ Time Frame: Pre-dose, 30 minutes, and 1, 2, and 3-4 hours post start of infusion ]
  Blood samples will be drawn at various time points to construct the blood activity curve. Urine data will also be included in our analyses to check the whole body clearance curves. A computer pharmacokinetic model containing 5 compartments including blood, liver, residual body, urine and feces will be used to analyze time activity data. Residence times for various organs will be calculated from this pharmacokinetic model and/or uptake data. Different residence times for different isotopes, e.g. 64Cu, will be calculated by adjusting for physical decay. These times are then substituted into the OLINDA program.
• Immunogenicity properties of copper Cu 64 anti-CEA monoclonal antibody M5A [ Time Frame: Up to 3 months ]
  The patient's serum samples are evaluated in both a bridging radioimmunoassay and an HPLC assay. The sera are incubated with the appropriate radiolabeled M5A and then analyzed by HPLC size exclusion chromatography on a Superose 6 HR column.

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: November 14, 2014)

Incidence of adverse events graded using the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03 [ Time Frame: Up to 3 months ]

Safety data will be displayed and abnormal laboratory values flagged. The frequency of adverse events will be tabulated by body system.

Descriptive Information

• Brief Title: Copper Cu 64 Anti-CEA Monoclonal Antibody M5A PET in Diagnosing Patients With CEA Positive Cancer
• Official Title: Pilot Study: Detection of Carcinomas Using 64Cu-Labeled M5A Antibody to Carcinoembryonic Antigen (CEA)
• Brief Summary: This pilot clinical trial studies copper Cu 64 anti-carcinoembryonic antigen (CEA) monoclonal antibody M5A positron emission tomography (PET) in diagnosing patients with CEA positive cancer. Diagnostic procedures, such as copper Cu 64 anti-CEA monoclonal antibody M5A PET, may help find and diagnose CEA positive cancer that may not be detected by standard diagnostic methods.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the ability of 64Cu labeled M5A antibody (copper Cu 64 anti-CEA monoclonal antibody M5A) to localize CEA positive cancers (such as gastrointestinal, lung, medullary thyroid and breast cancers), as determined by PET imaging.

SECONDARY OBJECTIVES:

I. To characterize the frequency of titer of the human anti-human antibody (HAHA) response to 64Cu labeled M5A antibody.

II. To determine the safety of administration of 64Cu labeled M5A antibody.

OUTLINE:

Patients receive copper Cu 64 anti-CEA monoclonal antibody M5A intravenously (IV) on day 0 and then undergo PET on day 1 and day 2.

After completion of study, patients are followed up at 1 and 3 months.
