The National Cancer Institute (NCI) is part of the National Institutes of Health (NIH), which is one of 11 agencies that compose the Department of Health and Human Services (HHS). The NCI, established under the National Cancer Institute Act of 1937, is the Federal Government's principal agency for ...
A radioimmunoconjugate comprised of the chimeric monoclonal antibody G250 conjugated with the positron emitter iodine I 124. The antibody moiety of iodine I 124 girentuximab may bind to renal cell carcinoma (RCC) cells that express the RCC-associated antigen G250, allowing detection of tumor-localized iodine I 124 with positron emission tomography (PET). G250 is a cell surface tumor-associated antigen (TAA) that is found in the majority of renal cell carcinomas.

A radioimmunoconjugate comprised of the chimeric monoclonal antibody G250 conjugated with the gamma-emitting radioisotope indium In 111. Indium I 111 chimeric monoclonal antibody G250 binds to G250, allowing the localization of G250-expressing tumor cells using gamma scintigraphy. Found in the majority of renal cell carcinomas (RCCs), G250 or carbonic anhydrase isozyme IX (CA IX) is a cell surface tumor-associated antigen (TAA).

A radioimmunoconjugate comprised of girentuximab conjugated with the bifunctional, macrocyclic chelating agent tetra-azacyclododecanetetra-acetic acid (DOTA) and lableled with the beta-emitting radioisotope yttrium Y 90. The antibody moiety of yttrium Y 90-DOTA-girentuximab binds to renal cell carcinoma cells expressing the G250 antigen, thereby selectively delivering a cytotoxic dose of beta radiation.

A radioimmunoconjugate comprised of the chimeric monoclonal antibody G-250 conjugated with iodine I 131 with potential antineoplastic activity. The antibody moiety of iodine I 131 chimeric monoclonal antibody G-250 binds to G-250, a renal-cell carcinoma-associated antigen, delivering cytotoxic iodine I 131 specifically to renal cell carcinoma cells that express G-250.

A radioimmunoconjugate comprised of a recombinant scFv dimer diabody of a monoclonal antibody against human carcinoembryonic antigen (CEA) labeled with iodine I 123 (I-123) with potential radioimmunolocalization applications. The antibody moiety of iodine I 123 anti-CEA recombinant diabody T84. 66 binds to cells expressing CEA, selectively delivering I-123 upon cellular internalization and allowing the scintigraphic imaging of CEA-expressing tumor cells. CEA, a tumor associated antigen, is overexpressed in many cancer types, including gastrointestinal, breast, non-small cell lung, and thyroid cancers. Compared to whole monoclonal antibodies, diabody fragments offer the advantages of rapid tumor targeting, rapid blood clearance, more uniform tumor distribution, and a lower potential for eliciting an immune response.

A radioimmunoconjugate comprised of a chimeric monoclonal antibody against human carcinoembryonic antigen (CEA) conjugated with the radioisotope yttrium 90 (Y-90) via the chelator tetra-azacyclododecanetetra-acetic acid (DOTA) with potential antineoplastic activity. The antibody moiety of yttrium Y90 DOTA anti-CEA monoclonal antibody cT84. 66 binds to cells expressing the CEA antigen. Upon cellular internalization, this agent selectively delivers a cytotoxic dose of beta radiation. CEA, a tumor associated antigen, is overexpressed in many cancer types, including gastrointestinal, breast, non-small cell lung, and thyroid cancers.

A radiofluorinated 2-nitroimidazole derivative with hypoxia-specific tracer activity. 18F-fluoroazomycin arabinoside is reduced under hypoxic conditions and is often seen in various malignant tumors, forming highly reactive intermediates. In its reduced form, 18F-fluoroazomycin arabinoside covalently binds to macromolecules, thereby accumulating in hypoxic cells and allowing radioisotopic imaging of these particular cells. Compared to 18F-misonidazole, 18F-fluoroazomycin arabinoside has a lower octanol:water partition coefficient; it therefore has less tendency to accumulate in lipophilic tissues and exhibits a faster renal clearance, leading to an improved imaging ability of hypoxic tissue.

A radiofluorinated 2-nitroimidazole derivate with hypoxia-specific tracer activity. Misonidazole is reduced under hypoxic conditions and in reduced form covalently binds to macromolecules in hypoxic cells. 18F (fluorine-18) radiofluorination of misonidazole to form 18F-fluoromisonidazole allows radioisotopic imaging of reduced misonidazole bound to macromolecules in hypoxic cells.
Industry:Pharmaceutical
A radioconjugate of biotin and yttrium Y 90 (Y-90) linked through the bifunctional macrocyclic chelating agent tetra-azacyclododecanetetra-acetic acid (DOTA) with radioimmunotherapy property. Biotin is a water-soluble B-complex vitamin, present in minute amounts in every living cell, while its level in cancerous tissue is higher than that of normal tissue. Y 90-DOTA-biotin could be used in 3-step pre-targeting radioimmunotherapy that employs a tumor targeting antibody conjugated with streptavidin, the natural ligand of biotin.

A radioconjugate containing the purine scaffold heat shock protein 90 (Hsp90) inhibitor PUH71 labeled with the radioisotope iodine I 124, with positron emitting activity. Hsp90 inhibitor PUH71 is thought to bind to cytosolic Hsp90 and the endoplasmic reticulum paralogue gp96 (HSP90B1), thereby inhibiting its molecular chaperone function and promoting the degradation of the oncogenic signaling proteins. This induces caspase-dependent apoptosis. The iodine I 124 moiety can be visualized using positron emission tomography (PET) imaging, thereby allowing an assessment of the accumulation of PUH71 in vivo, particularly in tumors. Hsp90, a chaperone protein upregulated in a variety of tumor cells, regulates the folding, stability and degradation of many oncogenic signaling proteins.
