Eluminex Biosciences Exclusively Licenses FibroGen’s Biosynthetic Cornea Technology and Recombinant Collagen III Platform

  • Exclusive Global Development and Commercialization Rights for Recombinant Human Collagen-Based Biosynthetic Cornea
  • Clinical Stage Asset Has Potential for First Approved Biosynthetic Human Cornea
  • Biosynthetic Cornea Designed to Address Significant Unmet Need in Global Demand for Corneal Grafts for the Treatment of Corneal Blindness
  • Edward Holland, MD, Joins Eluminex’s Scientific Advisory Board

SUZHOU, China and SAN FRANCISCO, July 19, 2021 (GLOBE NEWSWIRE) -- Eluminex Biosciences (Suzhou) Limited (Eluminex), an ophthalmology-focused biotechnology company headquartered in Suzhou, China with a US-subsidiary office in San Francisco Bay Area, California, announced today that it has exclusively licensed global rights for the development and commercialization of an investigational biosynthetic cornea derived from recombinant human collagen Type III intended to treat patients with corneal blindness, from FibroGen, Inc. (FibroGen; NASDAQ: FGEN).

“We are extremely excited to bring this novel technology initially to the China market to help meet a large unmet medical need for an alternative to human donor cornea tissue,” commented Dr. Jinzhong (“JZ”) Zhang, Chairman and CEO of Eluminex. “Over 100,000 cases of corneal blindness occur each year in China due to scarring from traumatic injury or infection that could be treated with a surgically implanted bioengineered cornea. Typical treatments in China include human donor corneal transplantation or use of corneal tissue harvested from genetically modified pigs. There is a significant shortage of human donor tissue and porcine corneas have issues with a lack of optical clarity and durability, however, and both methods require the need for additional immunosuppressive medications to prevent graft rejection. The biosynthetic cornea, that is optically clear, offers an alternative using human Type III collagen, a key structural protein that is found in normal human corneas and therefore does not require immunosuppressive medications.”

Under the terms of the agreement, Eluminex will make an $8 million upfront payment to FibroGen. In addition, FibroGen may receive up to a total of $64 million in future manufacturing, clinical, regulatory, and commercial milestone payments for the biosynthetic cornea program, as well as $36 million in commercial milestones for the first recombinant collagen III product that is not the biosynthetic cornea. FibroGen will also be eligible to receive royalties based upon worldwide net sales.

Eluminex also announced that Edward Holland, M.D., has joined the company’s Scientific Advisory Board (SAB). Charles Semba, M.D. and Chief Medical Officer of Eluminex commented, “We are excited to introduce Dr. Edward Holland, Professor of Ophthalmology at the University of Cincinnati and Director of the Cornea Service at the Cincinnati Eye Institute and past Chairman of the Eye Bank Association of America, as the newest member of our SAB. He is an internationally recognized expert in corneal allograft surgery and ocular surface disease. Additionally, over the past three decades, he has taught and lectured in China regarding corneal transplant techniques and will provide us critical insights into our biosynthetic cornea program.”

“The possibility for an abundant global supply of a biosynthetic human corneal tissue substitute has real potential to transform the lives of the hundreds of thousands of patients around the world in regions where corneal donations are scarce and who otherwise are unlikely to receive a sight-saving corneal transplant,” said Dr. Holland.

“We are pleased to enter into this agreement with Eluminex and license this technology to a seasoned ophthalmology team,” said Enrique Conterno, CEO of FibroGen. “This transaction enables FibroGen to focus on development of next generation biopharmaceutical therapies in our core areas of cancer, autoimmune and fibrotic diseases, and anemia.”

About the Eluminex Biosynthetic Cornea Program
The Eluminex biosynthetic cornea (EB-301) is a clinical stage corneal stromal substitute that will be initially developed for the China market. EB-301 is regulated as a Class III medical device and is anticipated to enter a clinical market authorization registration study in China in 2H 2022 to confirm its safety and effectiveness. The corneal device has been implanted in 10 patients in Europe with 4 years of follow-up and has demonstrated excellent biocompatibility, maintenance of optical clarity, and significantly improved visual acuity without immunosuppression. (Fagerholm et al, Biomaterials, 35 (2014): 2420-2427).

About Corneal Blindness in China
According to the World Health Organization, corneal diseases are one of the leading causes of blindness globally. Approximately 180,000 sight-restoring corneal transplantations are performed worldwide in which nearly a quarter are conducted in the United States. China is the largest most populous developing country in the world and corneal diseases are the second leading cause of blindness with an estimated 2-3 million patients with corneal blindness in at least one eye. However, due to the scarcity of donor corneas, only approximately 5000 to 9000 corneal transplants are conducted in China each year. Corneal porcine xenografts have been available in China since 2015 but technical issues remain with the lack of optical clarity and secondary immunologic complications (eg, graft dissolution and graft rejection). An unmet need exists for a suitable corneal stromal tissue replacement as an alternative to the shortage of donated human cornea and an alternative to porcine xenografts.
