GMO characterization

GMO is a:
Other: mammals

Identity of the GMO:
The GMO (CTX110) consists of human allogeneic T cells that are genetically modified ex vivo using CRISPR/Cas9 gene editing components and a recombinant AAV (rAAV) vector. The drug product is prepared from healthy donor peripheral blood mononuclear cells obtained via a standard leukapheresis procedure. The mononuclear cells are enriched for T cells and activated with anti-CD3-CD28 antibody-coated beads, then electroporated with CRISPR/Cas9 ribonucleoprotein complexes consisting of Cas9 and single guide RNA and transduced with a CAR gene-containing rAAV vector. The modified T cells are expanded in cell culture, purified, formulated into a suspension, and cryopreserved. The CRISPR/Cas9 system, along with an AAV-derived donor DNA template, has been used to create three edits in the genome of healthy donor T cells: T cell receptor alpha constant region (TRAC) disruption, β2-microglobulin (B2M) disruption, and site-specific incorporation of DNA sequence encoding a CD19-targeting CAR into the TRAC locus. The gene edits are intended to reduce the probability of Graft versus Host Disease (GvHD), improve persistence by reducing the probability of host rejection and direct the modified T cells towards CD19 expressing tumor cells.
The cells will be used only for therapeutic purposes.
