Minretumomab (CC49) is amousemonoclonal antibody[1] that was designed for the treatment ofcancers that express theTAG-72 antigen. This includesbreast,colon,lung, andpancreatic cancers.[2][3] Apparently, it never got pastPhase I clinical trials for this purpose.[4]

Derivatives

[edit]

A wide range of derivatives has been used in pharmaceutical research. Examples include chimeric[5] and humanized minretumomab,[6] as well as afusion protein of a minretumomabsingle-chain variable fragment and the enzymebeta-lactamase.[7]

Radiopharmaceuticals

[edit]

Iodine (125I) minretumomab is aniodine-125 radiolabelled derivative that was developed for the detection oftumours inradioimmunoassays such asCA 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 inducehuman anti-mouse antibodies; no tumour response was observed in Phase I and IIclinical trials.[5]
