  • Patent number: 10533059
    Abstract: The current invention discloses targeted drug delivery conjugates comprising a targeting moiety linked to a drug via a molecule having an affinity for the targeting moiety. Typically, the conjugate comprises a targeting ligand and a molecule of interest, e.g., a therapeutic agent. The targeting ligand and the molecule of interest are linked to each other via an affinity ligand. The affinity ligand is further covalently or non-covalently linked to a drug or therapeutic agent. The drug can be modified to make it more soluble and so that it cleaves from the linking molecule at the target site.

  • Patent number: 10426753
    Abstract: The present disclosure relates generally to supramolecular combinatorial therapeutics, compositions comprising same, and uses thereof. In particular, the present disclosure provides hydrophobic taxane-lipid covalent conjugates which create supramolecular assembly, for example, within lipid bilayer, providing an extra stabilization resulting in increased intratumoral concentration and hence increased efficacy. The present disclosure also provides supramolecular combinatorial therapeutics, wherein a taxane-lipid conjugate is combined with one or more of a platinum compound, a kinase inhibitor, and an immunoregulator, each of which is optionally conjugated with a lipid.
