  • Patent number: 9446155
    Abstract: The present invention provides polypeptides, peptide dimer, and multimeric complexes comprising at least one binding moiety for KDR or VEGF/KDR complex, which have a variety of uses wherever treating, detecting, isolating or localizing angiogenesis is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding KDR or VEGF/KDR complex with high affinity (e.g., having a KD<1 ?M), and dimer and multimeric constructs comprising these polypeptides.

  • Publication number: 20160263254
    Abstract: Peptide vectors having high KDR binding affinity and processes for making such vectors are provided. The peptide vectors may be conjugated to phospholipids and included in ultrasound contrast agent compositions. Such ultrasound contrast agents are particularly useful in therapeutic and diagnostic methods, such as in imaging KDR-containing tissue and in the evaluation and treatment of angiogenic processes associated with neoplastic conditions. The present invention also provides processes for the large scale production of highly pure dimeric and monomeric peptide phospholipid conjugates as well as precursor materials used to form the conjugates. The present invention further provides processes for the large scale production of highly pure peptide phospholipid conjugates which contain very low levels of TFA.

  • Patent number: 9408926
    Abstract: The present invention provides polypeptides, peptide dimers, and multimeric complexes comprising at least one binding moiety for KDR or VEGF/KDR complex, which have a variety of uses wherever treating, detecting, isolating or localizing angiogenesis is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding KDR or VEGF/KDR complex with high affinity (e.g., having a KD<1 ?M), and dimer and multimeric constructs comprising these polypeptides, particularly contrast agents. Also provided are methods for monitoring and evaluating the therapeutic effectiveness of treatment protocols for diseases associated with angiogenesis or endothelial cell hyperproliferation, such as cancer, using contrast agents of the invention.
