A federal funding company that helps high-impact analysis able to driving biomedical and well being breakthroughs has awarded as much as $47 million for a mission aimed toward transferring eye transplants to revive imaginative and prescient nearer to actuality. The six-year award from the Superior Analysis Tasks Company for Well being (ARPA-H) Transplantation of Human Eye Allografts (THEA) program is meant to supercharge an interdisciplinary effort to carry eye transplantation ahead to medical trial.
Up to now, just one whole-eye transplant has ever been efficiently carried out. The experimental process was a part of a face transplant operation by NYU Langone Well being surgeons in 2023. Whereas the transplanted eye was nonetheless viable one 12 months later, the organ has not but supplied sight.
The USC Roski Eye Institute on the Keck College of Drugs of USC is one in all eight organizations main the mission, often called Complete Human Eye-allotransplantation Innovation Development (THEIA). The group, led by Kia Washington, MD on the College of Colorado Anschutz Medical Campus, consists of Cedars-Sinai Medical Middle in Los Angeles, the Basis Preventing Blindness, Indiana College, Johns Hopkins College, the Nationwide Eye Institute and the College of Wisconsin–Madison.
The mission’s analysis technique consists of elements aimed toward preserving donated eyes to make sure they’re viable for transplant, attaching and repairing the optic nerve, and figuring out the logistical and technical particulars of the entire process via post-operative care. The method to pursuing this mission encompasses cutting-edge applied sciences, together with cell-based and gene-based therapies, in addition to units for augmenting exercise in nerves that USC’s group will direct.
Kimberly Gokoffski, MD, PhD, a neuro-ophthalmologist and surgeon-scientist on the Keck College of Drugs is main USC’s a part of the endeavor.
“Till ARPA-H created the chance, the idea of eye transplantation felt too sci-fi, too out of attain, for a lot of,” mentioned Gokoffski, a Dean’s Affiliate Professor of Scientific Ophthalmology on the medical faculty and Affiliate Director for Analysis on the USC Institute for Expertise and Medical Methods, a joint initiative of the Keck College of Drugs and USC Viterbi College of Engineering. “Nevertheless, due to current medical and scientific developments, loads of us started to understand that this was one thing price pursuing.”
Convening the suitable experience for this problem required bringing collectively a singular mix of educational medical facilities, a non-public basis and a authorities institute. Researchers in THEIA are already far alongside in growing the applied sciences and strategies concerned.
Gokoffski performs a management function in two THEIA goal areas: advancing a system for guiding nerve progress with electrical stimulation; and creating the protocols for figuring out appropriate donors and sufferers, performing the attention transplant process and aftercare.
“There’s loads of work to be finished, for example, optimizing the steadiness of what you protect within the affected person and what you harvest from the donor,” she mentioned.
To perform these targets, Gokoffski has assembled a group of researchers from USC and the College of California, Irvine. The members characterize a various array of disciplines: ophthalmology, neurosurgery, neurobiology and bioengineering. The group consists of Gianluca Lazzi, PhD, the director of the USC Institute for Expertise and Medical Methods, Mark Humayun, MD, PhD, the inventor of an FDA-approved “bionic eye” gadget for restoring imaginative and prescient, and Arthur Toga, PhD, a world-renowned knowledgeable in mind imaging.
Engineers and biologists and clinicians all assume otherwise, and we’re understanding the significance of convergent analysis linking totally different colleges of thought. Interdisciplinarity is a energy at USC, and one thing we hope to capitalize on. We even have a convention of success and excellence -; researchers with expertise taking a know-how actually from idea to the working room -; and that custom is backing us up.”

She has additionally partnered with corporations resembling Neurotech, which produces an implant that releases progress elements, and Boston Scientific, whose mind implants are presently used to deal with numerous neurologic circumstances. For Gokoffski, participating companions in business is integral to accelerating progress.
“I do not take into account this to be an exploratory or discovery award however moderately an opportunity to display efficacy,” she mentioned. “We’re taking what we all know works and attempting it out together with advances made by different specialists within the subject. I needed to search out collaborators probably to assist translate the science to the clinic, as quick as doable.”
{The electrical} stimulation for guiding nerve progress would come from a collection of units implanted within the eye and the mind. One key node can be a cuff across the space the place donated and host tissue meet. The thought is to not solely apply an electrical subject but additionally ship biologic remedies that help nerve survival and reduce irritation. This know-how will benefit from the native methods wherein the physique makes use of electrical energy to transmit data and information wound therapeutic.
“In the event you solely drive progress of neurons from inside, it is sort of like hitting the fuel with out controlling the steering,” Gokoffski mentioned. “The electrical fields do present fuel, however they primarily present the steering cue. Our analysis primarily goals to make use of pure mobile responses to electrical fields to information the nerves to develop to the place they should develop. If we rewire improperly, sufferers might expertise visible confusion.”
As soon as the preclinical work has been accomplished, the USC Roski Eye Institute will recruit and enroll potential sufferers. Gokoffski will then join with Dr. Darrin Lee, MD, PhD, a neurosurgeon and Affiliate Director of the Neurorestoration Middle at USC, Dr. Kia Washington and different plastic surgeons from CU Anschutz, and transplant surgeons from Cedars-Sinai to carry out the attention transplantation and post-operative care at Cedars-Sinai. Comply with-up assessments will happen on the USC Roski Eye Institute.
Gokoffski provides that the trail from the lab to the clinic will undoubtedly name for added collaborations. Future companions might embody philanthropists interested by contributing to the restoration of sight and traders interested by bringing element applied sciences to the market.
“To attain the largest targets, we actually want to hitch collectively and pool our assets,” Gokoffski mentioned. “Bringing folks collectively to attain a giant objective is strictly what ARPA-H is attempting to do.”
