This collaboration already generated an upfront payment of $75 million for Eli Lilly and Company.

Why it matters

The potential financial upside for Eli Lilly and Company is substantial, with the possibility of receiving over $400 million in milestone payments and royalties. This revenue is directly tied to the clinical and regulatory success of AAV-AIPL1, a gene therapy designed to treat Leber congenital amaurosis 4 (LCA4). The progress of this drug through the FDA and EMA regulatory pathways is therefore critical to realizing this financial potential.

This partnership highlights the growing trend of pharmaceutical companies licensing advanced gene therapy technologies. MeiraGTx, which holds all rights to bota-vec following its May 2026 acquisition from Johnson & Johnson, is actively advancing multiple programs, demonstrating a strategy of leveraging proprietary platforms to secure major licensing deals with established pharmaceutical giants like Eli Lilly and Company.
