  • Publication number: 20240116983
    Abstract: Compounds having activity for lowering parathyroid hormone levels are described. In one embodiment, the compounds are comprised of a contiguous sequence of subunits, X1—X2—X3—X4—X5—X6—X7, wherein the X1 subunit comprises a thiol-containing moiety and the distribution of charge on the X2—X7 subunits provides the desired activity. Methods of using the compounds for treating hyperparathyroidism, bone disease and/or hypercalcemic disorders are also described, and in particular, methods for lowering plasma PTH and serum calcium are provided. The compounds can be used to treat subjects having, for example: primary, secondary or tertiary hyperparathyroidism; hypercalcemia of malignancy; metastatic bone disease; or osteoporosis.

  • Patent number: 11479593
    Abstract: Described herein are cholix-IL-10 fusion proteins, and methods of use thereof, which can be characterized by a distinct response in an individual when administered. This distinct response can comprise changes in levels of one or more markers in the individual and/or co-localization of IL-10 in the lamina propria of the individual. Further described herein, in some embodiments, are oral formulations of the cholix-IL-10 fusion proteins. Described herein are methods for the purification of an IL-10 delivery construct, including methods for refolding and enrichment, which can result in maintenance of a high percentage of the IL-10 delivery constructs in the biologically active dimer form. Described herein are oral formulations configured for site-specific release of a therapeutic protein in the small intestines or colon. In some cases, the therapeutic protein is in the form of a dimer, such as an IL-10 delivery construct capable of crossing the gut epithelium.

  • Publication number: 20220282239
    Abstract: The disclosed invention relates to methods of modifying peptide compositions to increase stability and delivery efficiency. Specifically, the disclosed invention relates to methods to increase the stability and delivery efficiency of protein kinase C (PKC) modulatory peptide compositions. A “therapeutic peptide composition” comprises a “carrier peptide” and a “cargo peptide.” A “carrier peptide” is a peptide or amino acid sequence within a peptide that facilitates the cellular uptake of the therapeutic peptide composition. The “cargo peptide” is a PKC modulatory peptide. Peptide modifications to either the carrier peptide, the cargo peptide, or both, which are described herein increase the stability and delivery efficiency of therapeutic peptide compositions by reducing disulfide bond exchange, physical stability, reducing proteolytic degradation, and increasing efficiency of cellular uptake.

  • Publication number: 20210100911
    Abstract: The present disclosure provides delivery constructs comprising a carrier coupled to a heterologous payload, wherein coupling of the carrier to the payload can result in transportation of the payload (e.g., a therapeutic payload) into and/or across intact polarized epithelial cells (e.g., epithelial cells of the gut of a mammal). The delivery construct can be part of a pharmaceutical composition that can be orally administered to a subject to provide for improved, effective therapies for treatment of, e.g., inflammatory diseases or autoimmune diseases.
