PURPOSE Recent studies from this laboratory with (212)Pb-trastuzumab have shown the feasibility of targeted therapy for the treatment of disseminated peritoneal disease using (212)Pb as an in vivo generator of (212)Bi. The objective of the studies presented here was improvement of the efficacy of alpha-particle radioimmunotherapy using a chemotherapeutic(More)
PURPOSE Studies herein explore paclitaxel enhancement of the therapeutic efficacy of alpha-particle-targeted radiation therapy. EXPERIMENTAL DESIGN Athymic mice bearing 3 day i.p. LS-174T xenografts were treated with 300 or 600 microg paclitaxel at 24 h before, concurrently, or 24 h after [213Bi] or [212Pb]trastuzumab. RESULTS Paclitaxel (300 or 600(More)
Several monoclonal antibodies are now approved for cancer therapy, such as rituximab, an anti-CD20 monoclonal antibody for the treatment of B-cell non-Hodgkin's lymphoma. Such 'naked' antibodies can recruit the body's immune effector mechanisms to kill cells expressing the target of the antibody. In recent years, the linking of radionuclides to antibodies(More)
These studies demonstrate the feasibility of targeted therapy for the treatment of disseminated peritoneal disease using (212)Pb-labeled Herceptin as an in vivo generator of (212)Bi. In vitro studies compare the potential of the bismuth radioisotopes, (213)Bi and (212)Bi, to that of (212)Pb. Overall, (212)Pb results in a higher therapeutic index than either(More)
The studies reported herein demonstrate the efficacy of alpha-particle-targeted radiation therapy of peritoneal disease with Herceptin as the targeting vehicle. Using the CHX-A-DTPA linker, Herceptin was radiolabeled with indium-111 and bismuth-213 with high efficiency without compromising immunoreactivity. A pilot radioimmunotherapy study treating mice(More)
BACKGROUND Human epidermal growth factor receptor-2 (HER-2) and tumor-associated glycoprotein 72 (TAG-72) have proven to be excellent molecular targets for cancer imaging and therapy. Trastuzumab, which binds to HER-2, is effective in the treatment of disseminated intraperitoneal disease when labeled with (213)Bi or (212)Pb. (213)Bi-humanized CC49(More)
An antibody-targeted radiation therapy (radioimmunotherapy, RIT) employs a bifunctional ligand that can effectively hold a cytotoxic metal with clinically acceptable complexation kinetics and stability while being attached to a tumor-specific antibody. Clinical exploration of the therapeutic potential of RIT has been challenged by the absence of adequate(More)
Extract: Hybridoma/monoclonal antibody (mAb) technology as described in Kohler and Milstein's work resurrected Ehrlich's century old concept of "magic bullets." This seminal publication described fusion of a plasmacytoma (tumor of activated B lymphocytes) with spleen cells and subsequent isolation of hybrids that secreted mAb with pre-defined specificity.(More)
Novel chelates PIP-DTPA, AZEP-DTPA, NETA, NPTA, and PIP-DOTA were synthesized and evaluated as potential magnetic resonance imaging (MRI) contrast enhancement agents. The T1 and T2 relaxivities of their corresponding Gd(III) complexes are reported. At clinically relevant field strengths, the relaxivities of the complexes are comparable to that of the(More)
Few articles contemplate the need for good guidance in question item-writing in the continuing education (CE) space. Although many of the core principles of sound item design translate to the CE health education team, the need exists for specific examples for nurse educators that clearly describe how to measure changes in competence and knowledge using(More)
