Minretumomab (CC49) is a mouse monoclonal antibody[1] that was designed for the treatment of cancers that express the TAG-72 antigen. This includes breast, colon, lung, and pancreatic cancers.[2][3] Apparently, it never got past Phase I clinical trials for this purpose.[4]
Derivatives
A wide range of derivatives has been used in pharmaceutical research. Examples include chimeric[5] and humanized minretumomab,[6] as well as a fusion protein of a minretumomab single-chain variable fragment and the enzyme beta-lactamase.[7]
Radiopharmaceuticals
Iodine (125I) minretumomab is an iodine-125 radiolabelled derivative that was developed for the detection of tumours in radioimmunoassays such as CA 72-4.[8]
Radiolabelled minretumomab has also been tested for the treatment of solid tumours, but without success. Iodine (131I) and lutetium (177Lu) minretumomab, for example, were shown to induce human anti-mouse antibodies; no tumour response was observed in Phase I and II clinical trials.[5]
