Publication number: 20240009316Abstract: 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.Type: ApplicationFiled: November 3, 2022Publication date: January 11, 2024Inventors: Randall J. Mrsny, Charles Olson, Sally Postlethwaite, Thomas Carl Hunter, Tahir Mahmood, Weijun Feng

Patent number: 11479593Abstract: 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.Type: GrantFiled: October 27, 2021Date of Patent: October 25, 2022Assignee: Applied Molecular Transport Inc.Inventors: Derek Maclean, Randall J. Mrsny, Kevin Yin, Tahir Mahmood, Bittoo Kanwar, Sally Postlethwaite, Weijun Feng, Sean Dalziel, Hyojin Kim, Rajendra Tandale, Marvin Garovoy, John Koleng
