  • Publication number: 20220042035
    Abstract: The application describes ceDNA vectors having linear and continuous structure for delivery and expression of a transgene. ceDNA vectors comprise an expression cassette flanked by two ITR sequences, where the expression cassette encodes a transgene. Some ceDNA vectors further comprise cis-regulatory elements, including regulatory switches. Further provided herein are methods and cell lines for reliable gene expression in vitro, ex vivo and in vivo using the ceDNA vectors. Provided herein are method and compositions comprising ceDNA vectors useful for the expression of an antibody or fusion protein in a cell, tissue or subject. Such antibodies or fusion proteins can be expressed for treating disease or alternatively, for the production of antibodies or fusion proteins in a commercial setting.

  • Publication number: 20210388379
    Abstract: Described herein are ceDNA vectors having linear and continuous structure can be produced in high yields and used for effective transfer and expression of a transgene. According to some embodiments, ceDNA vectors comprise at least one heterologous nucleotide sequence operably positioned between two flanking symmetric inverted terminal repeat sequences that are not wild-type AAV ITR, wherein all or part of the heterologous nucleotide sequence is under the control of at least one regulatory switch. Some ceDNA vectors provided herein further comprise cis-regulatory elements and provide high gene expression efficiencies. Further provided herein are methods and cell lines for reliable and efficient production of the linear, continuous and capsid-free DNA vectors.
