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 challenge geared toward transferring eye transplants to revive imaginative and prescient nearer to actuality. The six-year award from the Superior Analysis Initiatives 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 scientific trial.
To this point, 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 offered sight.
The USC Roski Eye Institute on the Keck College of Medication of USC is one in every of eight organizations main the challenge, often known as Whole Human Eye-allotransplantation Innovation Development (THEIA). The staff, led by Kia Washington, MD on the College of Colorado Anschutz Medical Campus, consists of Cedars-Sinai Medical Middle in Los Angeles, the Basis Combating Blindness, Indiana College, Johns Hopkins College, the Nationwide Eye Institute and the College of Wisconsin–Madison.
The challenge’s analysis technique consists of parts geared 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 by post-operative care. The method to pursuing this challenge 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 staff will direct.
Kimberly Gokoffski, MD, PhD, a neuro-ophthalmologist and surgeon-scientist on the Keck College of Medication 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,” stated Gokoffski, a Dean’s Affiliate Professor of Scientific Ophthalmology on the medical college and Affiliate Director for Analysis on the USC Institute for Expertise and Medical Programs, a joint initiative of the Keck College of Medication and USC Viterbi College of Engineering. “Nevertheless, due to latest medical and scientific developments, quite a lot of us started to understand that this was one thing value pursuing.”
Convening the suitable experience for this problem required bringing collectively a novel mix of educational medical facilities, a non-public basis and a authorities institute. Researchers in THEIA are already far alongside in creating the applied sciences and strategies concerned.
Gokoffski performs a management position in two THEIA goal areas: advancing a system for steering nerve development with electrical stimulation; and creating the protocols for figuring out appropriate donors and sufferers, performing the attention transplant process and aftercare.
“There’s quite a lot of work to be executed, as an illustration, optimizing the stability of what you protect within the affected person and what you harvest from the donor,” she stated.
To perform these targets, Gokoffski has assembled a staff of researchers from USC and the College of California, Irvine. The members characterize a various array of disciplines: ophthalmology, neurosurgery, neurobiology and bioengineering. The staff consists of Gianluca Lazzi, PhD, the director of the USC Institute for Expertise and Medical Programs, Mark Humayun, MD, PhD, the inventor of an FDA-approved “bionic eye” machine for restoring imaginative and prescient, and Arthur Toga, PhD, a world-renowned professional in mind imaging.
Engineers and biologists and clinicians all assume in a different way, and we’re understanding the significance of convergent analysis linking totally different colleges of thought. Interdisciplinarity is a power at USC, and one thing we hope to capitalize on. We even have a practice of success and excellence -; researchers with expertise taking a expertise actually from idea to the working room -; and that custom is backing us up.”

She has additionally partnered with corporations corresponding to Neurotech, which produces an implant that releases development components, and Boston Scientific, whose mind implants are presently used to deal with quite a lot of neurologic situations. For Gokoffski, partaking companions in business is integral to accelerating progress.
“I do not think about this to be an exploratory or discovery award however reasonably an opportunity to display efficacy,” she stated. “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 most definitely to assist translate the science to the clinic, as quick as doable.”
{The electrical} stimulation for steering nerve development 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 concept is to not solely apply an electrical subject but additionally ship biologic remedies that assist nerve survival and reduce irritation. This expertise will benefit from the native methods through which the physique makes use of electrical energy to transmit data and information wound therapeutic.
“Should you solely drive development of neurons from inside, it is form of like hitting the gasoline with out controlling the steering,” Gokoffski stated. “The electrical fields do present gasoline, 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 extra collaborations. Future companions could embrace philanthropists focused on contributing to the restoration of sight and traders focused on bringing part applied sciences to the market.
“To realize the largest objectives, we actually want to hitch collectively and pool our sources,” Gokoffski stated. “Bringing folks collectively to attain a giant purpose is strictly what ARPA-H is attempting to do.“
