List of In-111- and Y-90-labeled monoclonal antibodies.
| Compound | Description | Applications | Remarks | 
|---|---|---|---|
| In111-Capromab pendetide (ProstaScint) | A conjugation between the murine antibody 7E11.C5.3 and 111In in the source of 111InCl3 by the action of the GYK-DTPA as a chelating agent. | Indicated for use in immunoscintigraphy, proven prostate carcinoma and patients who have undergone a prostatectomy and have rising prostate specific antigen (PSA) values and equivocal nonevidenced metastasis. | It is not indicated with patients with a high clinical suspicion of occult metastatic disease or for screening of prostate carcinoma. | 
|  | |||
| In111-Satumomab pendetide (OncoScint) | It contains the murine MAb B72.3 which is directed to tumor-associated glycoprotein. It is labeled with 111InCl3 by conjugation with the chelating agent, GYK-DTPA.HCl. | Used for the detection of colorectal and ovarian cancers [35]. | After an incubation time of 30 min, the labeled mixture is suitable for use in the first 8 hours. | 
|  | |||
| In111-Imciromab pentetate (MyoScint) | An antibody produced against myosin in the cell culture, and therefore binds to the heavy chain of myosin after in vivo administration. | Detection of myocardial infarction. | Contains the Fab fragment of a murine monoclonal antibody that is covalently bound to DTPA giving 111In -Imciromab pentetate. | 
|  | |||
| In-111 and Y90-ibritumomab tiuxetan (Zevalin) | Zevalin consists of a murine monoclonal anti-CD20 antibody covalently conjugated to the metal chelator DTPA, which forms a stable complex with 111In for imaging and with 90Y for therapy. | 90Y-ibritumomab tiuxetan is used for the treatment of some forms of B cell non-Hodgkin's lymphoma, a myeloproliferative disorder of the lymphatic system while its 111In derivative is used to scan the predicted distribution of a therapeutic dosage of 90Y-ibritumomab in the body [36]. | The antibody binds to the CD20 antigen found on the surface of normal and malignant B cells (but not B cell precursors) allowing radiation from the attached isotope (Yetrium-90) and the cytotoxicity induced by the antibody serve to eliminate B cells from the body allowing a new population of healthy B cells to develop from lymphoid stem cells [37]. | 
|  | |||
| Rituximab | An earlier version of anti-CD20 antibody and has also been approved under the brand name Rituxan for the treatment of non-Hodgkin's lymphoma (NHL). | It was approved for the treatment of patients with relapsed or refractory, lowgrade or follicular Bcell NHL, including patients with rituximab refractory follicular NHL. | In September 2009, ibritumomab received approval from the FDA for an expanded label for the treatment of patients with previously untreated follicular NHL, who achieve a partial or complete response to first-line chemotherapy. |
