About this study

Official title: Pre-Surgical Detection of Colorectal Carcinomas Using 123Iodine-Labeled cT84.66 Diabody Antibody Fragments to Carcinoembryonic Antigen (CEA)

RATIONALE: Diagnostic procedures, such as immunoscintigraphy, using a radiolabeled monoclonal antibody may help find and diagnose colorectal cancer.

PURPOSE: This clinical trial is studying how well immunoscintigraphy using a radiolabeled monoclonal antibody works in finding tumor cells in patients with colorectal cancer.

OBJECTIVES:

Primary

  • To determine the ability of iodine I 123 anti-CEA recombinant diabody T84.66 to localize to colorectal cancer, as determined by quantitative radioimmunoscintigraphy in patients with colorectal cancer.

Secondary

  • To evaluate the clinical pharmacokinetics of iodine I 123 anti-CEA recombinant diabody T84.66 clearance in these patients.
  • To characterize the frequency and titer of the human anti-chimeric response to iodine I 123 anti-CEA recombinant diabody T84.66 in these patients.
  • To determine the safety of iodine I 123 anti-CEA recombinant diabody T84.66 in these patients.

OUTLINE: Patients receive an infusion of iodine I 123 anti-CEA recombinant diabody T84.66. Patients undergo planar imaging every 5 minutes during the radiolabeled antibody infusion and then at 3-6 hrs, 12-24 hours, and, if indicated, 30-48 hours after the radiolabeled antibody infusion. Planar spot images of the head, chest, abdomen, and pelvis and whole body images (anterior and posterior) are taken. Patients also undergo SPECT scan of the abdomen and pelvis at 12 and 24 hours after the radiolabeled antibody infusion.

Blood samples are collected for pharmacokinetic analysis immediately after the radiolabeled antibody infusion and then at 15 minutes, 30 minutes, 1 hour, 2 hours, and 4 hours after the radiolabeled antibody infusion.

Patients are followed periodically for 6 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing pharmacological study, single photon emission computed tomography and iodine I 123 anti-CEA recombinant diabody T84.66 in people with Colorectal Cancer, 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 6 Nov 2017. 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?

Tumor targeting properties of iodine I 123 anti-CEA recombinant diabody T84.66 (time frame: Day 2 post infusion). 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 6 Nov 2017.
