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.
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.
