  • Publication number: 20230190927
    Abstract: Compounds, compositions and methods are provided for the inhibition of ENPP1. Aspects of the subject methods include contacting a sample with a cell impermeable ENPP1 inhibitor to inhibit cGAMP hydrolysis activity of ENPP 1. Also provided are vaccine compositions and methods relate thereto. Aspects of the methods include administering to a subject an effective amount of a cell impermeable ENPP1 inhibitor to inhibit the hydrolysis of cGAMP in combination with a vaccine.

  • Publication number: 20100311671
    Abstract: Disclosed herein are methods for transdermal delivery of PKC modulatory peptides. Generally, methods comprise the delivery of an isozyme specific PKC peptide modulator through skin that has been microporated, e.g., with an array of microneedles. Such methods may be used to administer therapeutically effective amounts of an isozyme selective PKC peptide inhibitor or activator.

  • Publication number: 20080161357
    Abstract: The invention features devices and methods for the systemic delivery of fentanyl or a fentanyl congener (e.g., sufentanil) to treat pain. In the present invention, a drug formulation comprising fentanyl or a fentanyl congener is stored within a drug delivery device (e.g., contained in a reservoir or impregnated within a matrix within the controlled drug delivery device). The drug formulation comprises an amount of drug sufficient for treatment and is stable at body temperatures (i.e., no unacceptable degradation) for the entire pre-selected treatment period. The drug delivery devices store the drug formulation safely (e.g., without dose dumping), provide sufficient protection from bodily processes to prevent unacceptable degradation of the formulation, and release the drug formulation in a controlled fashion at a therapeutically effective rate to treat pain.

  • Patent number: 6835194
    Abstract: The invention features devices and methods for treatment of pain. The drug delivery device is a drug delivery system adapted for whole implantation in a subject and to provide pain relief by delivery of fentanyl or a fentanyl congener (e.g., sufentanil) over a protracted period of time (e.g., at least 3 days or more than 3 days). The device comprises a housing defining a reservoir that contains a drug formulation, a pump operatively connected to the housing so as to facilitate movement of drug out of the reservoir and out of the device, and a thermal expansion element which defines a flow pathway comprising a thermal expansion channel to accommodate thermal expansion of formulation in the reservoir. The device can further comprise a valve positioned within the flow pathway so as to prevent movement of drug out of the reservoir prior to use.
