Development of Anterior Segment Focused Biologic Therapies to Regenerate Corneal Tissue for the Treatment of Disease:...

On February 24-27, 2021, the Association for Ocular Pharmacology and Therapeutics (AOPT) held its 15th biennial scientific meeting online. The meeting was organized by Dr. Sanjoy Bhattacharya of the University of Miami in conjunction with the board of trustees of the AOPT. The 3-day conference was attended by academic scientists, clinicians, and industry and regulatory professionals. The theme of the meeting was Restoring Vision through Regeneration and it was sponsored, in part, by the National Institutes of Health, Bright Focus, Regeneron, and Santen (USA). During the 3 days of the meeting, presentations from several sessions explored different aspects of regenerative medicine in ophthalmology, including optic nerve regeneration, drugs and devices in glaucoma, retinal neuroprotection and plasticity, visual perception, and degeneration of trabecular meshwork. This article summarizes the proceedings of the session on corneal regenerative medicine research and discusses emerging concepts in drug development for corneal epithelial and endothelial regeneration. Since the meeting in 2021, several of these concepts have advanced to clinical-stage therapies, but so far as of 2023, none has been approved by regional regulatory authorities in the United States. One form of corneal endothelial cell therapy has been approved in Japan and only for bullous keratopathy. Ongoing work is proceeding in the United States and other countries. Clinical Registration No: National Clinical Trials 04894110, 04812667; Japan Registry for Clinical Trials a031210199.
