Bacillus anthracis is a powerful agent for use in biological warfare, and infection with the organism is associated with a high rate of mortality, underscoring the need for additional effective therapies for anthrax. Radioimmunotherapy (RIT) takes advantage of the specificity and affinity of the antigen-antibody interaction to deliver a microbicidal radioactive nuclide to a site of infection. R...

Identifying molecular targets and an appropriate targeting vehicle, i.e., monoclonal antibodies (mAb) and their various forms, for radioimmunotherapy (RIT) remains an active area of research. Panitumumab, a fully human and less immunogenic mAb that binds to the epidermal growth factor receptor (Erb1; HER1), was evaluated for targeted α-particle radiation therapy using 212Pb, an in vivo α genera...

Radioimmunotherapy (RIT) after an induction phase with conventional chemoimmunotherapy became an attractive strategy of consolidation for patients with advanced follicular lymphoma: in particular, in many studies RIT was represented by yttrium-90-ibritumomab tiuxetan ((90) Y-IT). Independently by the different front-line treatment, updates on the long-term follow-up of these studies are needed ...

Rituximab therapy is associated with a long in vivo persistence, yet little is known about the effect of circulating rituximab on B-cell non-Hodgkin lymphoma (B-NHL) targeting by the other available anti-CD20 monoclonal antibodies (MoAbs) (131)iodine-tositumomab and (90)yttrium-ibritumomab tiuxetan. Therefore we assessed the impact of preexisting rituximab on the binding and efficacy of second ...

BACKGROUND Today's standard treatment of advanced-stage ovarian cancer, including surgery followed by a paclitaxel-platinum-based chemotherapy, is limited in efficacy. Recently, we could show that radioimmunotherapy (RIT) with (177)Lu-labelled anti-L1 cell adhesion molecule (L1CAM) monoclonal antibody chCE7 is effective in ovarian cancer therapy. We investigated if the efficacy of anti-L1CAM RI...

radioimmunotherapy (rit) of non-hodgkin’s lymphoma (nhl) is said to be more advantageous compared to unlabelled therapeutic antibodies. to this date, radiolabelled murine anti-cd20 mabs, zevalin® and bexxar® have been approved for imaging and therapy. a preparation containing rituximab, chimeric mab radioimmunoconjugate suitable for lu-177 labeling, could provide better imaging and therapeutic ...

UNLABELLED The extra domain B of fibronectin (ED-B) is a marker of tumor angiogenesis. The human monoclonal antibody (mAb) L19-SIP (approximately 80 kDa; SIP is "small immunoprotein") has been selected for targeting of ED-B. The aim of this study was to evaluate the potential of radioimmunotherapy (RIT) with L19-SIP, either alone or in combination with cetuximab, for treatment of head and neck ...

Radioimmunotherapy (RIT) has emerged as an effective treatment for lymphoma, however the underlying mechanisms are poorly understood. We therefore investigated the relative contributions of antibody and targeted radiation to the clearance of tumor in vivo, using 2 different syngeneic murine B-cell lymphoma models. Although RIT with (131)I-anti-major histocompatibility complex class II (MHCII) w...

Radioimmunotherapy (RIT) has demonstrated potential for improving clinical cancer therapy. Optimizing the approach has proven difficult thus far. Antibody phage display libraries provide unique molecules that could improve RIT. A phage display library of single chain antibody fragments (scFv) against the MUC-1 mucin molecule, which is expressed on 90% of human breast cancers, was produced from ...

BACKGROUND For individualized treatment planning in radioimmunotherapy (RIT), correlations must be established between tracer-predicted and therapy-delivered absorbed doses. The focus of this work was to investigate this correlation for tumors. METHODS The study analyzed 57 tumors in 19 follicular lymphoma patients treated with I-131 tositumomab and imaged with SPECT/CT multiple times after t...
