Trial summary

RATIONALE: Monoclonal antibodies can locate tumor cells and deliver tumor-killing substances, such as radioactive iodine, to them without harming normal cells.

About this study

Official title: Phase I Study of 131I-Labeled Humanized Antibody A33 in Patients With Advanced Colorectal Carcinoma

RATIONALE: Monoclonal antibodies can locate tumor cells and deliver tumor-killing substances, such as radioactive iodine, to them without harming normal cells.

PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody in treating patients with advanced colorectal cancer.

Read the detailed description

OBJECTIVES: I. Define the toxicity and determine the maximum tolerated dose of iodine I 131 humanized monoclonal antibody A33 (131I-huAb A33) in patients with advanced colorectal cancer. II. Describe pharmacokinetics and biodistribution of 131I-huAb A33 by external imaging in these patients. III. Determine the effect of human antihuman antibody response on pharmacokinetics and targeting of 131I-huAb A33 in this patient population. IV. Determine whether the dose planning methodology used here can adequately and safely be applied to routine radioimmunotherapy planning.

OUTLINE: Patients receive iodine I 131 humanized monoclonal antibody A33 (131I-huAb A33) by IV infusion over 20 minutes every 6-8 days for up to 8 weeks (depending on dosage). Patients receive a minimum of 6 weeks of treatments. In the absence of disease progression or unacceptable toxicity, patients are retreated no sooner than 6 weeks after the previous course. Cohorts of 3-6 patients receive escalating doses of 131I-huAb A33 to determine the maximum tolerated dose (MTD). The MTD is defined as the highest dose at which no more than 2 of 6 patients experience dose limiting toxicity. Patients are followed for 6 weeks after the last treatment.

PROJECTED ACCRUAL: There will be 3-24 patients accrued into this study over 16 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing iodine I 131 monoclonal antibody A33 in people with Colorectal Cancer, run by Memorial Sloan Kettering Cancer 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 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.

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 Jan 2013.
