Our DNA
Johns Hopkins University School of Medicine
Our DNA
Graybug Vision was founded in 2011 as a spin-out of the world-renowned Wilmer Eye Institute of the Johns Hopkins University School of Medicine. Graybug Vision’s initial technology was co-developed by co-founder, Justin Hanes, PhD, who is the Lewis J. Ort Professor of Ophthalmology and Director of Nanomedicine at the Wilmer Eye Institute of the Johns Hopkins University, in collaboration with co-founders and leading ophthalmology clinician-scientists from the Wilmer Eye Institute, Peter A. Campochiaro, MD and Peter J. McDonnell, MD.
“The discovery of new compositions and methods to produce non-inflammatory polymer microparticles, followed by the discovery of methods to load multiple relevant drugs into the microparticles and release them continuously for up to 12 months, were key milestones that ultimately led to the spin-out of Graybug Vision.”
Justin Hanes, PhD
Co-Founder
“We knew that sunitinib was a potent pan VEGF-R inhibitor with neuroprotective features. Thanks to our non-inflammatory microparticle platform technology, we could make it last for a very long time. Fast-forwarding to today, GB-102 is Graybug’s lead formulation in clinical development for wet AMD. It has shown to provide effective levels of sunitinib for at least six months following intravitreal injection.”
Justin Hanes, PhD
Co-Founder
“VEGF signaling plays a critical role in wet AMD and diabetic retinopathy, and our experiments with the sunitinib sustained-release formulation showed outstanding efficacy and durability. I believe that Justin’s expertise in polymer chemistry and sustained delivery matched very well with my expertise in ocular neovascular diseases and animal models. Our collaboration has provided Graybug Vision with multiple compounds that have the potential to greatly improve the lives of many patients with ocular diseases.”
Peter Campochiaro, MD
Co-founder
“One of the biggest challenges we face with the current anti-VEGF treatments for retinal diseases is that they don’t last very long. This is a tremendous burden on patients. They have difficulty keeping up with the needed frequency of visits and injections, and as a result they tend to get recurrent disease and lose vision over time. So, what excites me most about Graybug Vision’s technology is the promise of a treatment that could last six months or longer with a single injection.”
