About this study
Official title: Phase I Trial of 131I-HuCC49^CH2 for Colon Cancer
Phase I trial to study the effectiveness of radiolabeled monoclonal antibody therapy in treating patients who have recurrent or persistent metastatic colorectal cancer. Radiolabeled monoclonal antibodies can locate tumor cells and deliver tumor-killing substances to them without harming normal cells. Radiolabeled monoclonal antibody therapy may be effective treatment for colorectal cancer
Read the detailed description
PRIMARY OBJECTIVES:
- Determine the maximum tolerated dose of iodine I 131 monoclonal antibody CC49-deltaCH2 (deleted CH2 region) in patients with colorectal cancer.
II. Determine the toxic effects, plasma pharmacokinetics, whole body biodistribution, and conjugate stability of this drug in these patients.
III. Determine the ability of this drug to localize to tumor sites in these patients.
IV. Determine the immune response in patients treated with this drug.
OUTLINE: This is a dose-escalation study.
Patients receive a tracer dose of iodine I 131 monoclonal antibody CC49-deltaCH2 IV on day 1 and a therapy dose over 30 minutes on day 8.
Cohorts of 3-5 patients receive escalating doses of iodine I 131 monoclonal antibody CC49-deltaCH2 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 3 of 5 patients experience grade 3 or greater toxicity while 0-2 of 5 patients experience reversible grade 4 hematologic toxicity.
Patients are followed weekly for a minimum of 7 weeks and then every 6 weeks until disease progression.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing iodine I 131 monoclonal antibody CC49-deltaCH2 in people with Adenocarcinoma of the Colon and Adenocarcinoma of the Rectum, run by National Cancer Institute (NCI) 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?
The sponsor lists 31 inclusion and 0 exclusion criteria. 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 25 Jan 2013. 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 of 131I-HuCC49^CH2 based on dose-limiting toxicities (time frame: 6 weeks). 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 25 Jan 2013; AzTrials last refreshed its copy on 8 Nov 2026.
