About this study
Official title: A Phase I Study of Yttrium-90 Labeled Humanized Anti-CEA M5A Antibody in Patients With CEA Producing Advanced Malignancies
RATIONALE: Radiolabeled monoclonal antibodies, such as yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A, can find tumor cells and carry tumor-killing substances to them without harming normal cells. This may be an effective treatment for advanced cancer.
PURPOSE: This phase I trial is studying the side effects and best dose of yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A in treating patients with advanced solid tumors.
Read the detailed description
OBJECTIVES:
- To establish the maximum tolerated dose of yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A and describe the toxicities at each dose studied.
- To estimate radiation doses to whole body, normal organs, and tumor through serial nuclear imaging studies after intravenous infusion of the yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A.
OUTLINE: This is a dose-escalation study of yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A (MOAB M5A).
- Biodistribution: Patients receive indium In 111 radiolabeled anti-CEA MOAB M5A IV over 30 minutes. Patients undergo serial nuclear scans, single photon emission computed tomography (SPECT), and blood and urine sampling over 1 week to estimate absorbed radiation doses to tumor, normal organs (i.e., liver, lung, kidney, and bone marrow), and whole body.
- Treatment: No more than 2 weeks later, patients with adequate biodistribution receive yttrium Y 90 DOTA anti-CEA MOAB M5A IV over 30 minutes on day 1. Patients then undergo serial nuclear scans, SPECT, and blood and urine sampling over 1 week to estimate absorbed radiation doses to tumor, normal organs (i.e., liver, lung, kidney, and bone marrow), and whole body. Treatment repeats every 6-10 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity.
Blood and urine samples are collected periodically for analysis of total activity by radiometric high performance liquid chromatography and to acquire data on antibody metabolism and pharmacokinetics.
After completion of study treatment, patients are followed every 3 months for up to 6 months.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing high performance liquid chromatography, pharmacological study and radionuclide imaging in people with Unspecified Adult Solid Tumor, Protocol Specific, run by City of Hope Medical Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum tolerated dose (time frame: 10 weeks after the beginning of the last cycle of treatment). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
