Trial summary

Hu14.18K322A is a monoclonal antibody developed at St. Jude Children's Research Hospital (SJCRH) that is made to bind to cancer cells that have a molecule called GD2 on their surface. Sometimes the human body will make an antibody to the therapeutic antibody (like hu14.18K322A) that is being given for treatment. Read more about this study

About this study

Official title: Characterization of Pretreatment Anti-Therapeutic Antibodies (PATA) in Patients Treated With hu14.18K322A Antibody

Hu14.18K322A is a monoclonal antibody developed at St. Jude Children's Research Hospital (SJCRH) that is made to bind to cancer cells that have a molecule called GD2 on their surface. Sometimes the human body will make an antibody to the therapeutic antibody (like hu14.18K322A) that is being given for treatment. These are called human anti-human antibodies (HAHA). When testing for HAHA in a previous cohort of patients who received hu14.18K322A, it was found that some patients tested positive for high levels of an antibody before receiving hu14.18K322A or any other anti-GD2 antibody. In this study, investigators would like to know more about the nature of this pretreatment antibody, how often is it present, and if in the laboratory it increases the killing of tumor cells.

OBJECTIVES:

  • To determine whether pretreatment anti-therapeutic antibodies (PATA) represent antibodies reactive against an epitope (allotypic determinant) found on the anti-GD2 antibody hu14.18K322A
  • To determine if PATA increases the anti-tumor efficacy of anti-GD2 antibodies in vitro
Read the detailed description

In the proposed study, investigators will seek to determine the nature of this antibody that is being detected in the HAHA test for this group of patients, and if, in the laboratory, it increases the killing of tumor cells, accounting for the observation that some the patients who tested positive may have an improved outcome.

The study will analyze DNA from blood samples of SJCRH patients treated with hu14.18K322A anti-GD2 antibody. Serological studies and confirmatory genotyping studies will be performed in a laboratory at the University of Wisconsin.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Characterization of PATA

    Objective: To determine whether pretreatment anti-therapeutic antibodies (PATA) represent antibodies reactive against an epitope (allotypic determinant) found on the anti-GD2 antibody hu14.18K322A

    Measured: Once at participant enrollment

  2. Number of samples with increased anti-tumor efficacy

    Objective: To determine if PATA increases the anti-tumor efficacy of anti-GD2 antibodies in vitro

    Measured: Once, at enrollment

Questions about this trial

What is this clinical trial studying?

An observational study of Ewing Family of Tumors and Melanoma, run by St. Jude Children's Research Hospital 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 1 inclusion and 1 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 5 Nov 2020. 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.

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?

Characterization of PATA (time frame: Once at participant enrollment). 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 5 Nov 2020; AzTrials last refreshed its copy on 8 Nov 2026.
