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 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 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 yr later, the organ has not but supplied sight.
The USC Roski Eye Institute on the Keck Faculty of Drugs of USC is one in all eight organizations main the challenge, often known as Complete Human Eye-allotransplantation Innovation Development (THEIA). The crew, led by Kia Washington, MD on the College of Colorado Anschutz Medical Campus, contains 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 contains 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 by means of post-operative care. The strategy to pursuing this challenge encompasses cutting-edge applied sciences, together with cell-based and gene-based therapies, in addition to gadgets for augmenting exercise in nerves that USC’s crew will direct.
Kimberly Gokoffski, MD, PhD, a neuro-ophthalmologist and surgeon-scientist on the Keck Faculty 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 college and Affiliate Director for Analysis on the USC Institute for Expertise and Medical Techniques, a joint initiative of the Keck Faculty of Drugs and USC Viterbi Faculty of Engineering. “Nevertheless, due to latest medical and scientific developments, plenty of us started to appreciate that this was one thing value pursuing.”
Convening the best experience for this problem required bringing collectively a singular mix of educational medical facilities, a personal basis and a authorities institute. Researchers in THEIA are already far alongside in growing the applied sciences and methods concerned.
Gokoffski performs a management position in two THEIA goal areas: advancing a system for guiding 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 plenty of work to be accomplished, as an 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 crew of researchers from USC and the College of California, Irvine. The members signify a various array of disciplines: ophthalmology, neurosurgery, neurobiology and bioengineering. The crew contains Gianluca Lazzi, PhD, the director of the USC Institute for Expertise and Medical Techniques, Mark Humayun, MD, PhD, the inventor of an FDA-approved “bionic eye” system for restoring imaginative and prescient, and Arthur Toga, PhD, a world-renowned knowledgeable in mind imaging.
Engineers and biologists and clinicians all assume in another way, and we’re understanding the significance of convergent analysis linking completely different faculties 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 equivalent to Neurotech, which produces an implant that releases development components, and Boston Scientific, whose mind implants are at present used to deal with various neurologic circumstances. For Gokoffski, partaking companions in business is integral to accelerating progress.
“I do not take into account this to be an exploratory or discovery award however reasonably an opportunity to show efficacy,” she mentioned. “We’re taking what we all know works and attempting it out together with advances made by different specialists within the discipline. I needed to seek out collaborators more than likely to assist translate the science to the clinic, as quick as potential.”
{The electrical} stimulation for guiding nerve development would come from a sequence of gadgets implanted within the eye and the mind. One key node could be a cuff across the space the place donated and host tissue meet. The thought is to not solely apply an electrical discipline but additionally ship biologic therapies that assist nerve survival and decrease irritation. This expertise will make the most of the native methods by which the physique makes use of electrical energy to transmit data and information wound therapeutic.
“When you solely drive development of neurons from inside, it is type of like hitting the gasoline with out controlling the steering,” Gokoffski mentioned. “The electrical fields do present gasoline, however they primarily present the steering cue. Our analysis basically 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 concerned about contributing to the restoration of sight and traders concerned about bringing part applied sciences to the market.
“To attain the largest objectives, we actually want to hitch collectively and pool our sources,” Gokoffski mentioned. “Bringing folks collectively to realize an enormous objective is strictly what ARPA-H is attempting to do.“
