Patent number: 12246046Abstract: Provided herein are compositions and methods for the treatment of type 1 diabetes (T1D) in mammalian subjects. The compositions include lactic acid fermenting bacteria (LAB) expressing an IL-2 gene and a T1D-specific self-antigen (e.g., proinsulin (PINS)) gene. Exemplary methods include: orally administering to a mammalian subject, a therapeutically effective amount of the composition. The composition can be administered to the subject mucosally, resulting in delivery of the LAB into the gastrointestinal tract, where the LAB is released. Bioactive polypeptides expressed by the LAB are thus administered via mucosal delivery. The LAB may be selected to deliver a low-dose of IL-2 to the subject. The methods may not require concomitant systemic anti-CD3 antibody treatment. The methods may be suited for subjects possessing residual beta-cell function, e.g., those with recent-onset T1D.Type: GrantFiled: September 8, 2023Date of Patent: March 11, 2025Assignee: INTREXON ACTOBIOTICS N.V.Inventors: Pieter Rottiers, Lothar Steidler

Publication number: 20230348918Abstract: The current disclosure provides microorganisms, such as lactic acid bacteria (e.g., Lactococcus lactis) containing an exogenous nucleic acid encoding an IL-10 polypeptide and an exogenous nucleic acid encoding a T1D-specific antigen (e.g., a proinsulin) polypeptide, wherein both exogenous nucleic acids are integrated into the bacterial chromosome. Such microbial strains are suitable for human therapy. The disclosure further provides compositions (e.g., pharmaceutical compositions) methods of using the microorganisms and compositions, e.g., for the treatment of type 1 diabetes (T1D), including those with residual beta-cell function, e.g., recent-onset T1D. The microorganism may be administered orally, delivers the microorganism into the gastrointestinal tract, where it is released and expresses the bioactive polypeptides. The methods of the present disclosure are particularly well suited for subjects possessing residual beta-cell function, e.g., for subjects with recent-onset T1D.Type: ApplicationFiled: November 29, 2022Publication date: November 2, 2023Inventors: Pieter Rottiers, Lothar Steidler
