Official title

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

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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
