Abstract: The present invention is directed to a peptide or polypeptide comprising an Fv molecule, a construct thereof, a fragment of either, or a construct of a fragment having enhanced binding characteristics so as to bind selectively and/or specifically to a target cell in favor of other cells, wherein the binding selectivity or specificity is primarily determined by a first hypervariable region, and wherein the Fv is a scFv or a dsFv, and optionally having one or more tags. The enhanced binding is directed to a substantially exposed and/or over-expressed binding site on or in a target comprising a cell in favor of other cells on or in which the binding site is not substantially available and/or expressed. The invention is further directed to a method for isolating such peptides and polypeptides from a phage display library and to the nucleic acid molecules encoding them.

Abstract: The present invention is directed to novel peptides and polypeptides that specifically bind to target cells and may have anti-cancer activity, especially blood-related cancers. The present invention includes a peptide or polypeptide comprising an Fv molecule, having a heavy variable chain comprising CDR3, CDR2 and CDR1 regions comprising the amino acid sequences SEQ ID NOS:8, 115 and 114, respectively.

Abstract: The present invention relates to compositions utilizing an agent and an antibody, or fragment thereof. In these compositions, the agents, including agents such as anti-cancer, anti-metastasis, anti-leukemia, anti-disease, anti-adhesion, anti-thrombosis, anti-restenosis, anti-autoimmune, anti-aggregation, anti-bacterial, anti-viral, and anti-inflammatory agents, can be complexed or combined with or conjugated to the antibodies, or fragments thereof. In addition, the agent and/or the antibody, or fragment thereof, can be present in the composition in a sub-clinical amount, which is an amount that is less than the amount of the agent generally found to be clinically effective when the agent is administered alone. Preferably, in these compositions of the present invention, the agent is an anthracycline or a derivative thereof, e.g., doxorubicin (adriamycin) or a derivative thereof.
