Eli Lilly's in vivo CAR-T therapy using circular RNA and lipid nanoparticles to make patients' own cells into CAR-T cells in the body, designed for B cell-driven autoimmune diseases.
Acquired from Orna Therapeutics (Feb 2026); clinical trial-ready, targeting in vivo CAR-T development.
Checked 10 Oct0 updates this week
The circular RNA is packaged in LNPs and injected into patients to reach target cells without ex vivo removal and modification.
The looped structure of circular RNA makes it more stable in the body than linear RNA, allowing longer-lasting therapeutic protein expression.
The circular RNA instructs patient cells to produce CAR-T receptors on their surface, letting them recognize and kill CD19+ B cells driving autoimmune disease.
