Lilly to acquire Orna Therapeutics to advance cell therapies
Orna is advancing a new class of therapeutics utilizing engineered circular RNA paired with novel lipid nanoparticles to allow the patient’s own body to generate cell therapies that can treat underlying disease.
Orna’s lead program is ORN-252, a clinical trial-ready, CD19 targeting in vivo Chimeric Antigen Receptor T-cell (CAR-T) therapy designed to treat B cell-driven autoimmune diseases. Experiments to date suggest that Orna’s circular RNA platform may deliver more durable expression of therapeutic proteins and therefore unlock treatments that are not feasible with current RNA or cell therapy platforms.
Up to USD 2.4 billion in cash
Under the terms of the agreement, Lilly will acquire Orna, and Orna shareholders could receive up to USD 2.4 billion in cash, inclusive of an upfront payment and subsequent payments upon achievement of certain clinical development milestones.
“Early autologous CAR-T studies have shown the promise of cell therapy for patients with autoimmune diseases, but the complexity, cost, and logistics of ex vivo approaches make it challenging to deliver these breakthroughs to the broader population of patients who need them,” said Francisco Ramírez-Valle M.D., Ph.D., Senior Vice President, Head of Immunology Research and Early Clinical Development. “We look forward to working with Orna colleagues to potentially unlock an entirely new class of genetic medicines and cell therapies for patients who today have limited or no treatment options.”
