  • Publication number: 20250276075
    Abstract: Methods for treatment of Axl-expressing cancers are provided. The methods involve administering to a subject in need thereof, a polypeptide having a heavy chain variable region and/or light chain variable region that specifically binds to Axl protein, antibodies or antibody fragments containing the polypeptide, and/or an immunoconjugate compound thereof. The immunoconjugate compound is a Conditionally Active Biologic (CAB) anti-Axl antibody conjugated to one or more drug(s) via a cleavable linker (CAB-Axl-ADC). The immunoconjugate is a mAbBA3011-cleavable linker-MMAE (n) or pharmaceutically acceptable salt thereof, in which the mAbBA3011 is an antibody or antibody fragment, the MMAE is monomethyl auristatin E, and the (n) is an integer between 1 and 4.

  • Publication number: 20250242012
    Abstract: A system for delivering a payload nucleic acid into target cells of a subject and production of a payload (or payloads) encoded by the payload nucleic acid in the cells. The system includes a Bifidobacterium sp. bacterium comprising a plasmid and a transporter nucleic acid, the transporter nucleic acid configured for expression in the bacterium. The transporter nucleic acid encodes a transporter polypeptide comprising, in an amino-terminal to carboxy-terminal order, a bacterial secretion signal peptide, a DNA-binding domain to bind the plasmid, and a cell penetrating peptide. The transporter polypeptide complexes with the plasmid and transports the plasmid from the bacterium into the target cells. The plasmid encodes one or more payloads (protein and/or ribonucleic acid) for production in the target cells. The target cells may be colonic cells. When the payload(s) include an antigen, the system may be a DNA vaccine.
