Problem
Current genome engineering techniques face challenges in delivering large genetic payloads with precision and without causing double-stranded breaks, hindering the development of effective in vivo gene therapies. Existing methods often lack the capacity for complex, multigenic therapeutic payloads needed to address many diseases.
Solution
Stylus Medicine is developing in vivo genetic medicines using engineered recombinases to enable targeted insertion of any-length genetic sequences into the human genome. Their platform utilizes a novel class of enzymes designed to recognize a safe harbor site in the genome and introduce therapeutic payloads with high specificity and integrity. By leveraging cell-targeted lipid nanoparticles (LNPs), Stylus Medicine aims to deliver therapeutic payloads directly to immune cells in vivo, with an initial focus on creating in vivo CAR-T therapies. This approach has the potential to transform patient treatment, improve accessibility, and redefine possibilities in medicine across oncology, autoimmune diseases, genetic disorders, and beyond.
Target Audience
The primary target audience includes patients with genetic diseases, cancer, and autoimmune disorders, as well as pharmaceutical companies and research institutions focused on developing in vivo gene therapies and CAR-T cell therapies.
