We are Focused on Delivering Life-Changing Therapies to Patients
Kate Therapeutics is advancing the DELIVER capsid engineering platform to evolve AAV capsid variants that enable potent and selective delivery to target tissues. DELIVER combines diverse capsid library generation with stringent transcript-based in vivo selection and machine learning to evolve functional capsid variants in any cell type of interest in any in vivo model.
DELIVER has been used to evolve a novel class of MyoAAV-LD (liver de-targeted) muscle-tropic capsids, which transduce both skeletal muscle and cardiac tissue with superior potency and selectivity compared to both naturally occurring AAV serotypes (e.g., AAV9, AAV8, AAVrh74) and other engineered capsids, while actively avoiding the liver. These vectors show conserved transduction potency in mice, non-human primates (NHPs), and human muscle cells. Kate Therapeutics is currently advancing sixth generation MyoAAV-LD capsids that enable dramatic de-targeting of the liver, while effectively transducing skeletal muscle and heart tissues after systemic administration in mice and NHPs, further increasing the safety margin for these vectors.
