  • Patent number: 9914754
    Abstract: The present invention features a compound having the formula A-X-B, where A is peptide vector capable of enhancing transport of the compound across the blood-brain barrier or into particular cell types, X is a linker, and B is a peptide therapeutic selected from the group consisting of neurotensin, a neurotensin analog, or a neurotensin receptor agonist. The compounds of the invention can be used to treat any disease in which increased neurotensin activity is useful and can be used to induce hypothermia or analgesia.

  • Publication number: 20180015180
    Abstract: The present invention relates to short polypeptides (e.g., fewer than 19 amino acids in length) and longer polypeptides (e.g., 19 or more amino acids in length) having one or more D-amino acids as targeting moieties. These polypeptides, when conjugated to agents (e.g., therapeutic agents or transport vectors) are capable of transporting the agents across the BBB or into particular cell types. In particular, the short polypeptides can include one or more D-amino acids. These compounds are therefore particularly useful in the treatment of neurological diseases or diseases associated with particular cell types, organs, or tissues.

  • Publication number: 20170281787
    Abstract: The present invention relates to antibody-polypeptide-cytotoxin conjugates and methods of making, packaging, and using the conjugates. The polypeptide can be a Kunitz-type protease inhibitor or a derivative thereof that facilitates transport of the conjugate across the blood-brain barrier and/or into cancer cells outside the CNS, and the antibody moiety selectively binds a target within the CNS or in peripheral tumors to direct the cytotoxic agent to that target (e.g., a tumor or cancer cell). The conjugates can be further defined by the inclusion of a linker between the antibody moiety and the polypeptide; by the number of polypeptides and cytotoxic agents conjugated thereto; by the positions at which the entities within the conjugates are bound to one another; and by the larger configuration of the conjugate. Modified polypeptides (e.g., polypeptides conjugated to cytotoxic agents but not to an antibody moiety), pharmaceutical compositions, kits (e.g.

  • Patent number: 9173891
    Abstract: Ovarian cancer is treated with conjugates of an anticancer agent and an Angiopep-2 polypeptide analog (i.e. a polypeptide comprising an amino acid sequence at least 80% identical to Seq. ID NO:97). Such treatment includes utility in treating metastatic ovarian cancer and in treating patients who have previously exhibited resistance to standard chemotherapeutic agents. Preferred anticancer agents include taxanes while the preferred conjugate is ANG1005, a conjugate comprising three molecules of paclitaxel conjugated to the peptide Angiopep-2.

  • Patent number: 9161988
    Abstract: The present invention relates to multimeric (e.g., dimeric, trimeric) forms of peptide vectors that are capable of crossing the blood-brain barrier (BBB) or efficiently entering particular cell types. These multimeric peptide vectors, when conjugated to agents (e.g., therapeutic agents) are capable of transporting the agents across the BBB or into particular cell types. These compounds are therefore particularly useful in the treatment of neurological diseases.

  • Publication number: 20150290341
    Abstract: The present invention is related to a compound that includes a lysosomal enzyme and a targeting moiety, for example, a compound that includes iduronate-2-sulfatase conjugated to Angiopep-2 through a linker formed by specific click chemistry reactions. In certain embodiments, these compounds, owing to the presence of the targeting moiety, can cross the blood-brain barrier or accumulate in the lysosome more effectively than the enzyme alone. The invention also features pharmaceutical compositions containing such compounds and methods for treating lysosomal storage disorders (e.g., mucopolysaccharidosis Type II) using such compounds.

  • Publication number: 20150174267
    Abstract: The present invention is directed to conjugates that include a polypeptide capable of crossing the blood-brain barrier or entering one or more cell types attached to a transport vector, i.e., a composition capable of transporting an agent (e.g., a therapeutic agent). In certain cases, the polypeptides are directly conjugated to a lipid or polymeric vector to allow targeted application of a therapeutic agent to treat, for example, a cancer, a neurodegenerative disease, or a lysosomal storage disorder.
