THE GRAYBUG VISION

We work relentlessly to save sight through transformative science, creating solutions to treat vision-threatening diseases, that improve quality of life and care for all involved.

THE DISEASES WE SOLVE FOR

Approximately 80 million Americans are affected by potentially blinding eye disease and this number is projected to double by 2030 based on an aging population and the increasing prevalence of diseases that can cause vision loss.
Our Proprietary Technologies
Graybug is a clinical-stage biopharmaceutical company focused on developing transformative medicines for ocular diseases. Our diversified portfolio is designed to treat vision-threatening diseases of the retina, optic nerve, and cornea, by either maintaining effective drug levels in ocular tissues for long periods of time, using innovative technologies such as injectable sustained-release formulations, or by curing diseases with gene therapies.

OUR PIPELINE
Based on our proprietary technologies, our R&D pipeline targets a range of chronic vision-threatening diseases, some of which have no viable treatment option.
GB-102 is a microparticle formulation of a pan-VEGF inhibitor, sunitinib, for the treatment of wet age-related macular degeneration designed for a twice-per-year intravitreal injection. GB-102 has the potential to also benefit patients with diabetic retinopathy.
GB-102
GB-401 is a first-in-class implant formulation containing a novel prodrug of timolol for the treatment of primary open angle glaucoma (POAG) designed for a twice-per-year intravitreal injection with a proprietary applicator.
GB-401
GB-501 is an adeno-associated virus (AAV) gene therapy with Orphan Drug Designation (ODD) and Rare Pediatric Disease Designation (RPDD) to treat corneal clouding caused by Mucopolysaccharidosis Type 1 (MPS1), a lysosomal storage disorder.
GB-501
GB-601 is being developed as a long-acting formulation of a novel cGMP analog to address hereditary retinal diseases like Retinitis Pigmentosa, a group of genetic disorders that involve a loss of cells in the retina.
GB-601
GB-701 is being developed as a long-acting formulation of a potent factor B inhibitor targeting the complement cascade which plays a role in AMD.
