  • Patent number: 11766467
    Abstract: Diabetic wounds have elevated levels of cathepsin K, a protease enzyme, which degrades proteins, such as collagen, causing delayed wound healing. By targeting cathepsin K, diabetic wound healing is ameliorated. Methods and devices for treatment include intradermal injection of odanacatib at or adjacent a wound. Methods and devices for treatment include topical application of pharmacological inhibitors of cathepsin K, for example, in the form of gel, powder, or bandage. Other methods and systems include localized genetic knock out of the cathepsin K gene by topical application of a small interfering RNA (siRNA) or antisense oligonucleotide to aid in wound healing.

  • Patent number: 10201622
    Abstract: The present inventors have harnessed the targeting of nanoparticles to tumor sites, combined with the tumor site specific elevated MMP-14 activity within one conjugate to simultaneously deliver a vascular disrupting agent (VDA) and a MRI contrast agent to a tumor site. The MMP activatable conjugate of the present invention provides both therapeutic and diagnostic functions—and is referred to as a “theranostic”. The theranostic conjugate of the present invention achieves the benefits of tumor site specificity, VDA delivery and MRI contrast agent delivery in a single theranostic conjugate. Consequently, the present invention provides a cancer “theranostic” which improves therapeutic efficacy while simultaneously reducing dose-limiting systemic toxicities and provides a tool for rapidly and non-invasively identifying tumor location, monitoring drug delivery and pharmacodynamics.

  • Patent number: 10130674
    Abstract: Chemokine signaling is important in neuropathic pain, with microglial cells expressing CCR2 playing a well established key role. DAPTA, a gp120-derived CCR5 entry-inhibitor has been shown to inhibit CCR5-mediated monocyte migration and to attenuate neuroinflammation. We disclose here that as a stabilized analog of DAPTA, the short peptide All D TTNYT (SEQ ID NO:1) exhibits potent antagonism for both CCR2 (IC50 4.2 pM) and CCR5 (IC50 0.18 pM) in monocyte chemotaxis. Oral administration of All D TTNYT (SEQ ID NO:1) (0.05-1 mg/kg) for 7 days fully prevents mechanical allodynia and inhibits the development of thermal hyperalgesia following partial ligation of the sciatic nerve in rats. Administered from day 8 to day 12, All D TTNYT (SEQ ID NO:1) (0.2-1 mg/kg) reverses already established hypersensitivity.
