The Company’s anti-c-kit CAR-T program leverages its proprietary piggyBac Gene Delivery System and Cas-CLOVER Site-specific Gene Editing System to develop fully allogeneic CAR-T cells targeting human c-kit which is highly expressed on HSCs, as well as on myeloid malignancies such as acute myeloid leukemia (AML), meaning the treatment can be used for either HSC transplant conditioning or as a treatment for AML. In addition to the CAR gene, the piggyBac transposon includes a selection marker for generation of a pure CAR+ product and a proprietary fast-acting safety switch enabling rapid clearance of the reactive CAR-T cells prior to donor HSC transplant.
