Generation Bio to Apply ctLNP Delivery Technology to Develop siRNA Therapeutics for T Cell-Driven Autoimmune Diseases
Monday, 6th January at 4:30 pm
•Novel programs will combine validated cell-targeted LNP (ctLNP) delivery with siRNA to selectively modulate T cells in vivo
•Programs to focus on silencing hard-to-drug targets of high therapeutic value in T cell-driven autoimmune diseases
•Company reorganization supports evolution of ctLNP-enabled strategy and buildout of clinical capabilities ahead of first IND expected in 2H 2026
CAMBRIDGE, Mass., Jan. 06, 2025 (GLOBE NEWSWIRE) -- Generation Bio Co. (NASDAQ: GBIO) a biotechnology company working to change what is possible for people living with T cell-driven autoimmune diseases, announced it is leveraging its validated T cell-directed lipid nanoparticle (ctLNP) to develop siRNA therapeutics to silence disease-driving targets in T cells.



"We are excited to move Generation Bio toward the clinic by deploying our ctLNP to deliver siRNA to T cells. By precisely modulating T cell activity in vivo we believe we can address high-value, currently undruggable targets involved in the inflammation and tissue damage associated with T cell-driven autoimmune diseases," said Geoff McDonough, M.D., chief executive officer of Generation Bio. "Our aim is to silence therapeutic T cell targets without impacting other immune cell types, unlocking a powerful new application for siRNA in the field. We plan to submit our first IND in the second half of 2026 and to enter the clinic within our cash runway, which is into the second half of 2027."
siRNA delivery to T cells has historically been limited by the inability to achieve selective cell targeting combined with efficient access to the cytoplasm where siRNA operates, challenges that Generation Bio has designed its ctLNP to overcome. The company recently presented non-human primate data demonstrating that its ctLNPs work by targeting T cells through a target receptor of interest with a strong selectivity for CD8+ and CD4+ effector T cells and NK cells, all of which are involved in auto-reactive tissue damage in a number of autoimmune diseases.
