A preparation of autologous T lymphocytes that have been genetically modified to express a chimeric antigen receptor (CAR) specific for the CD30 antigen, with potential immunostimulating and antineoplastic activities. Upon administration, the CD30 CAR-expressing autologous T lymphocytes specifically recognize and bind to CD30-expressing tumor cells, resulting in tumor cell lysis. CD30, a cell surface receptor and a member of the tumor necrosis factor (TNF) receptor superfamily, is transiently expressed on activated lymphocytes and is constitutively expressed in hematologic malignancies. Check for active clinical trials using this agent. (NCI Thesaurus)
