As part of the collaboration, MeiraGTx will grant Lilly worldwide exclusive rights to its AAV-AIPL1 program for the treatment of Leber congenital amaurosis 4 (LCA4). Leber congenital amaurosis 4 is a severe, inherited eye disease that causes significant vision loss from birth. Symptoms include involuntary eye movements, sensitivity to light, high hyperopia, and a cone-shaped cornea.

Following treatment with AAV-AIPL1, 11 children who were born blind gained vision, the company said, while adding that the treatment also resulted in benefits in vital areas of development, including communication, behavior, learning, mood, psychological benefits, and social integration.

Terms Of The Collaboration

Lilly will also receive worldwide exclusive access rights to MeiraGTx’s gene therapy technologies for use in ophthalmology, in addition to certain rights to its proprietary riboswitch technology for use in gene editing in the eye.

In return, MeiraGTx will receive an upfront payment of $75 million and will be eligible to receive over $400 million in total milestone payments in addition to tiered royalties on licensed products.

“Ophthalmology is an emerging area of interest for Lilly,” said Andrew Adams, Lilly group vice president of Molecule Discovery.

“We are excited to partner with MeiraGTx to bring transformative treatments to patients around the world suffering from eye diseases, starting with AAV-AIPL1, which has shown the unprecedented ability to restore vision in children who were born legally blind,” he added.
