About this study
Official title: Phase I/II Study of 131I-Labeled Chimeric Antibody G250 (131I-cG250) in Patients With Advanced Renal Carcinoma
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.
PURPOSE: Phase I/II trial to study the effectiveness of monoclonal antibody therapy in treating patients with advanced kidney cancer.
Read the detailed description
This is a dose-escalation study. Initially patients receive a scout dose of iodine-131 radiolabeled chimeric monoclonal antibody G250 (131I-cG250) administered intravenously (IV) over 10 minutes to determine whole body clearance. One week later, patients receive incremental doses of 131I-cG250 IV over 10 minutes at 2-3 day intervals for 2-6 weeks,. Dose escalation begins at least 8 weeks after the last infusion of 131I-cG250. In the absence of dose-limiting toxicity in the first 3 patients treated, subsequent cohorts of 3 patients each receive escalating doses of 131I-cG250 on the same schedule. If dose-limiting toxicity occurs in 2 of 6 patients treated at a given dose level, then dose escalation ceases and the next lower dose is declared the maximum tolerated dose (MTD). Treatment continues once recovery from all toxic effects occurs, beginning 8 to 12 weeks following the last dose of 131I-cG250. Patients achieving complete remission, partial remission, or stable disease were eligible to receive up to 3 courses of treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Iodine-131 radiolabeled chimeric monoclonal antibody G250 (131I-cG250)Biological
cG250 is an IgG1 chimeric monoclonal antibody. It was supplied as a sterile solution at a concentration of 1.0 mg/mL in either a 2 mL or a 5 mL vial. cG250 was radiolabeled with Iodine-131 prior to use.
| Study group | Role | What they receive |
|---|---|---|
| Cohort 1 50cGy radiation | Experimental | On day 1, patients received a single dose of 131I-cG250 (5 mCi/5 mg) administered as an intravenous infusion over 10 minutes.
Therapeutic doses of 131I-cG250 were administered the following week as fractionated outpatient doses, starting with 30 millicurie (mCi)/5 mg 131I-cG250. Subsequent doses of 131I-cG250 were administered at 2-3 day intervals with the total amount of 131I-cG250 administered based on the calculated clearance of the initial dose administered on day 1. Whole body activity was maintained at no more than 30 mCi iodine-131.
In the absence of disease progression and after recovery from toxicity, patients could be re-treated beginning 8 weeks after the last treatment of the initial series, for a total of not more than 3 treatments.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Patients With Adverse Events (AEs)
All adverse events occurring during the study were to be recorded on the patient's case report form, and include the following information: a description; date of onset and resolution; severity; relationship to an investigational agent; action taken and outcome. Toxicity was graded in accordance with the NCI CTCAE version 3.0.
Measured: Up to 12 months
Number of Patients With Dose-Limiting Toxicities (DLTs)
Subjects were monitored for Adverse Events (AEs) for at least 8 weeks after the last infusion of 131I-cG250, or until recovery from all toxicity, and prior to dose escalation. Toxicity was graded in accordance with the Common Toxicity Criteria (CTC) of the National Cancer Institute (NCI) Version 3.0. Dose-Limiting Toxicity (DLT) was defined as grade 3 or greater toxicity related to study therapy. The maximum tolerated dose was defined as the highest safely tolerated dose where at most one of six patients experiences a DLT with the next higher dose having at least two patients who experience a DLT.
Measured: up to 12 months
Secondary outcomes (2)
Number of Patients With Best Overall Tumor Response
Tumor responses were evaluated using computed tomography and categorized according to World Health Organization (WHO) criteria at baseline and at no more than 6 weeks after the last dose, or not more than 12 weeks after entry into the study. Complete Response (CR): disappearance of all measurable disease lasting at least 1 month; Partial Response (PR): ≥ 50% decrease in the size of the product of 2 perpendicular diameters of any measurable lesions and no new lesions, lasting at least one month; Progressive Disease (PD): ≥ 25% increase in the size of any measurable lesions or the appearance of any new lesions; Stable Disease (SD): small changes that do not meet above criteria.
Measured: Up to 12 weeks
Number of Patients With Human Anti-chimeric Antibodies (HACA)
Blood samples were taken at baseline and in weeks 2, 3, 4, 5, and 6 as well as month 6. HACA was measured by an enzyme-linked immunosorbent assay (ELISA) using the "double antibody sandwich" technique and pretreatment serum as negative control.
Measured: Up to 6 months

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Iodine-131 radiolabeled chimeric monoclonal antibody G250 (131I-cG250) in people with Kidney Cancer, run by Ludwig Institute for Cancer Research 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 3 inclusion and 3 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 4 Oct 2023. 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Jan 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Patients With Adverse Events (AEs) (time frame: Up to 12 months). The study lists 2 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 4 Oct 2023; AzTrials last refreshed its copy on 8 Nov 2026.
