Pixium Vision announced its scientific program with multiple presentations of clinical and preclinical results at the Association for Research in Vision and Ophthalmology (ARVO) 2017 world congress in Baltimore May 7–11, the main annual event for research and innovation in ophthalmology. The presentations consist in 4 poster presentations and 3 podium talks, including IRIS retinotopic performance in human and latest insights into PRIMA’s pre-clinical performance and safety results.
Regarding the IRIS epiretinal bionic vision system, results showed a highly significant correlation (P < 0.001) between electrode stimulation position and perceived phosphene flash location in patient’s visual field. These results from the IRIS clinical study allow definition of stimulation strategies aiming to provide clinical benefit with the IRIS system.
Regarding the PRIMA wireless subretinal photovoltaic implant, the multiple presentations include results from the Vision Institute in Paris, demonstrating positive behavioural response via elicited visual perception with PRIMA implant in living non-human primates. Moreover, Stanford University team also presents positive behavioural results with prosthetic vision mediated by PRIMA implant in rats with retinal degeneration. These new pre-clinical data sets further strengthen Pixium Vision’s file for first-in-human studies which is being assessed by regulatory bodies.
“We are delighted to share the excellent advances made with both IRIS and PRIMA, our two retinal bionic vision systems, with the global vision research community at ARVO," Khalid Ishaque, CEO of Pixium Vision, said in a company news release. "The research results with IRIS in clinical study continue to add to clinical experience for improving patient outcomes and supporting commercialization activities following its regulatory approval in Europe. For PRIMA, our tiny wireless photovoltaic implant, the latest pre-clinical results presented at ARVO provide even greater support in planning and ongoing dialogue with the regulatory bodies for the first human studies.”
