NCI Drug Dictionary


iodine I 124 monoclonal antibody A33 
A radioimmunoconjugate of a humanized monoclonal antibody (MoAb) A33 labelled with iodine 124 (I-124). MoAb A33 recognizes A33 antigen, a 43 KDa transmembrane glycoprotein of the immunoglobulin superfamily, highly and homogenously expressed in 95% of colorectal cancer metastases, with only restricted expression in normal colonic mucosa. I-124 MoAb A33 delivers beta particle emitting I-124 nuclide directly to metastatic colorectal tissues, thereby this agent could be used in kinetics studies or radioimmunotherapy. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
