Bpifrance and Foundation Fighting Blindness have launched SparingVision to develop vision-saving treatment for Inherited Retinal Diseases. The newly established French company, SparingVision has won the 2017 i-Lab Grand Prize recognizing new and innovative companies. The i-Lab competition is organized by the French Ministry of Higher Education, Research and Innovation and Bpifrance (BPI).
BPI, the Foundation Fighting Blindness Clinical Research Institute (FFB-CRI), and the Fondation Voir & Entendre (FVE) created SparingVision earlier this year to advance an emerging therapy developed to preserve cones (light-sensing photoreceptor cells) within the retina. Preventing the loss of cones is central to preserving vision for people with blinding retinal diseases, including retinitis pigmentosa (RP) and Usher syndrome.
SparingVision is an equity funding partnership. A total of €15.5 million in milestone-based funding has been announced, with FFB-CRI and BPI each investing €7 million and FVE providing €1.5 million. The i-Lab prize includes €450,000 in additional funding.
SparingVision’s goal is to launch a clinical trial of the potential treatment, rod-derived cone-viability factor (RdCVF), within the next two years.
Rod-derived cone-viability factor (RdCVF) is a naturally occurring protein in the retina identified by SparingVision’s co-founders José Alain Sahel, MD, and Thierry Léveillard, PhD, at the Institut de la Vision. The scientists demonstrated in laboratory studies that RdCVF prevented or slowed the degeneration of cones, the cells in the retina that enable vision, thus allowing people to read, drive, and recognize faces. RdCVF is naturally secreted by rods, the retinal cells that provide night and peripheral vision.
If the new treatment successfully progresses through clinical trials and to the marketplace, the impact will be greatest within the RP community. RP, a genetic condition, is the most commonly occurring of the inherited retinal diseases, affecting about two million people worldwide. RP is typically diagnosed in early adulthood and leads to progressive vision loss over time. Usher syndrome affects both hearing and vision; the vision loss is due to the same cone-loss mechanisms as RP.
“Saving retinal cone cells is critical for preserving vision for people with genetic retinal diseases,” says Dr. Sahel, “After several years of investigation, we understand the mechanism of action for RdCVF and have demonstrated its strong efficacy in several lab studies.”“SparingVision’s emerging therapy has the potential to save vision for millions of people. I am delighted by our partners’ investment and to receive this prize. Our mission is to get RdCVF out to the people who desperately need it,” says Florence Ghrenassia, PhD, chief drug development officer at SparingVision. The Foundation Fighting Blindness Clinical Research Institute provided much of the early research funding to develop RdCVF.
“We have been excited about this therapy’s potential for saving vision for some time and therefore committed significant resources to boost its development,” says Patricia Zilliox, PhD, FFB-CRI’s chief drug development officer. “The establishment of SparingVision and the investment by our partners are essential to getting the treatment into the marketplace. We are pleased to be a part of this translational process.” “This therapeutic solution shows strong promise for being able to stop the progression of vision loss. We are very optimistic about the ability of SparingVision's team to make it available to the millions of patients whose lives it would change. This successful development also demonstrates the validity of our model ‘from bench to bedside,’ through the creation of innovative companies,” says Jean-Charles Pomerol, president of the Fondation Voir & Entendre, a shareholder of SparingVision.
