Improved gene delivery and T Cell editing using cell free DNA and novel non viral delivery solutions

On-Demand Webinar

Switching to enzymatically produced DNA formats and optimized non-viral delivery vehicles can address two of the most persistent bottlenecks in gene therapy development: DNA toxicity and suboptimal delivery efficiency. This session presents comparative data from two complementary platforms, examining how advanced DNA payload formats and lipid and polymer-based delivery systems can together reduce immune sensing, improve therapeutic dosing, and enhance T cell editing outcomes.

You will see head-to-head data comparing dbDNA and mbDNA against plasmid DNA across multiple delivery contexts, including systemic and local in vivo delivery and HDR-based T cell editing, alongside performance data for a preassembled lipid-based nanoparticle platform for RNA and DNA delivery into T cells.

watch this webinar to understand how combining advances in payload design and delivery platform selection can reduce reliance on viral vectors and support more efficient, scalable non-viral gene therapy programs.

What You Will Learn:

  1. Review in vivo data demonstrating superior expression magnitude and durability of dbDNA versus plasmid DNA across multiple organs after systemic delivery, and in muscle tissue via local administration using non-viral delivery solutions
  2. Examine T cell editing data showing improved HDR efficiency and cell viability using mbDNA and dbDNA compared to plasmid DNA, with implications for repeat dosing and immune evasion
  3. Explore the performance of a pre-formed vesicles (PFVs) solution, LipidBrick® Cell Ready, a lipid-based nanoparticle platform for stable editing and transient expression in T cells
  4. Gain practical guidance on selecting DNA payload formats and delivery formulations based on application requirements, without the need to develop these capabilities in-house
