The urgent mission of the Foundation Fighting Blindness is to support the development of treatments and cures for inherited retinal dystrophies. Gene therapy is emerging as a leading therapeutic approach for these predominantly monogenic diseases, especially following the December 2017 FDA approval of LUXTURNA® for the treatment of retinal diseases caused by biallelic pathogenic variants in the RPE65 gene. However, while gene therapy is very promising, both preclinical and clinical data indicate it stimulates the immune system and in doing so may be limiting optimal dosing and efficacy while also impacting clinical practice and study design.
This workshop is designed to bring together industry and academia to discuss openly what is known about the interactions of viral-mediated gene therapy of the retina with the immune system and the clinical consequences of that.
Given the projected trajectory of the COVID-19 pandemic, we recognize that an in-person workshop is unlikely to be feasible in the near future. The urgency of this topic, however, has not decreased. Therefore we have decided to hold the workshop in a virtual format.
The workshop will be held live on consecutive days, September 14 and 15, 2020, using Zoom. Introductory presentations will be pre-recorded and shared ahead of time. We ask participants to watch these ahead of the live meeting. The live meeting will consist of two 4-hour Zoom meetings, supported by pre-recorded videos, held on consecutive days. These introductory videos will be shared publicly following the workshop.
Expectation of Confidentiality
The live workshop will be recorded to assist Dr. Karen Elkins, the Science writer for the meeting. The workshop recording will not be shared publicly, unless all attendees agree, in which case elements of the recording may be edited to respect confidentiality.
Attendees are asked to respect the confidentiality of the meeting, to foster productive discussion. Specifically, attendees are asked not to:
- Share the workshop links
- Record the audio or video of the workshop
- Invite other colleagues or people to listen in to the workshop
- Understand the current state of knowledge of intraocular immunologic functions
- Understand the current knowledge of immune activation in inherited retinal diseased eyes prior to treatment
- Understand the mechanisms causing the non-clinical and clinical immune responses observed in ocular viral gene therapy
- Understand the limitations that immune responses place on optimizing outcomes
Prior to Meeting Assignment
To ensure everyone starts with the same core information about immunology and the processes that will be discussed during the workshop, we ask all attendees to watch the following pre-recorded presentations:
Virtual Workshop Agenda
Day 1 – Monday, September 14, 2020
Iceberg of Inflammation: Preclinical data - should we worry?
Overview of the Day
- How preclinical models develop our understanding:
- What is extent of inflammation and immune activation?
- What protocols are being used to control inflammation?
- Do animal models inform appropriately?
- Modifications of vector, capsid and transgene to reduce inflammation
Day 2 – Tuesday, September 15, 2020
Clinical Inflammation: What we know and contemporary clinical data
This session will be a discussion of preclinical and clinical data for gene therapies that have been, or still are, in the clinic. The presentations should focus on:
- Preclinical data that led to dose decisions and toxicology of concern
- Data that led to immunosuppression protocol
- Data on immune responses observed
- Data on clinical inflammation observed

Dr. Beltran is a Professor of Ophthalmology at the School of Veterinary Medicine of the University of Pennsylvania where he practices clinical veterinary ophthalmology and heads a research laboratory focused on inherited retinal degenerative diseases and the development of novel therapeutic strategies. Ongoing projects in his group are aimed at characterizing the link between mutation and photoreceptor cell death, and developing novel treatment modalities such as corrective gene therapy, neuroprotection, the use of optogenetic/optochemical tools for vision restoration, and stem cell therapies to replace photoreceptor cells. His work using canine models of IRDs has led to the development of gene therapies for RPGR-XLRP, RHO-ADRP, and NPHP5-LCA.
Dr. Beltran is also the Director of PennVet’s Division of Experimental Retinal Therapies (www.vet.upenn.edu/ExpeRTs), a unique consortium of veterinary ophthalmologists and vision scientists whose mission is to facilitate the development, screening, and testing of novel retinal therapies that rescue or restore vision in people and animals through collaborations with academia and industry.
Jean Bennett, MD, PhD
Director, Center for Advanced Retinal and Ocular Therapeutics (CAROT), University of Pennsylvania Perelman School of Medicine
Professor of Ophthalmology; Cell & Developmental Biology, University of Pennsylvania Perelman School of Medicine
Jean Bennett is a physician-scientist with experience/expertise in molecular biology, vector development and gene therapy translational studies. Dr. Bennett has established a true “from bench to bedside” program, and thus she is familiar with steps necessary to go from proof-of-concept all the way to those necessary for testing of safety and efficacy in humans with blinding disease. Dr. Bennett was the scientific leader of a team that translated reversal of blindness in animal models to demonstration of efficacy and safety in children and adults. Her team was the first to enroll pediatric subjects with a non-lethal disease as gene therapy participants. The team completed both a re-administration study and, with Spark Therapeutics (of which she is a scientific founder), a Phase 3 registration gene therapy trial for congenital blindness, the first randomized, controlled, multi-center gene therapy Phase 3 gene therapy trial targeting a genetic disease. This work led to the first approved gene therapy for inherited disease in USA (2017) and in Europe (2018) and more recently in the UAE (2019). This is also the first approved gene therapy product targeting a retinal disease worldwide. Through her Center, the Center for Advanced Retinal and Ocular Therapeutics (CAROT) at the University of Pennsylvania, Dr. Bennett continues to develop gene-based therapies for other retinal degenerative diseases and to tackle some of the limitations of current gene therapy technologies. She mentors scientists and physicians at all career stages, serves on a number of advisory panels, and is an active member of non-profit patient-oriented foundations.

Bill Merigan, PhD
Dr. Merigan’s current research interests include understanding the function of retinal ganglion cells (RGCs) in the fovea of normal macaques as well as developing optogenetic and cell-based therapies for restoring vision loss. These projects are complementary, since the quality of restored vision in many vision restoration approaches depends on knowledge of the specialized function of the ganglion cell classes mediating vision and how best to drive them. His expertise comes from years of studying the parallel pathways from the macaque retina to the brain, using visual psychophysics, in which monkeys maintain steady fixation in order that test stimuli can be placed at retinal locations to be tested. Recently, in collaboration with David Williams, he has developed a macaque model for in vivo measurement of the function of RGCs using a calcium indicator inserted into RGCs by intravitreal injection. In some cases, optogenetic agents have also been inserted into the same RGCs in order to examine optogenetic vision restoration. The well-known challenge of these studies is that transgene expression (GFP, G-CaMP, or optogenetics) is typically confined to a narrow annulus around the fovea, apparently a result of the ILM as a barrier to vector penetration. Recently Dr. Merigan has been able to spatially extend the ring of RGC expression substantially by treatment of the monkey with cyclosporine prior to injection.
