ASP7317 for Geographic Atrophy | Plus, Moo Adam, MD, on IV-Free Surgery

Guests: Marci English, MPH – Senior Vice President, Biopharma and Ophthalmology Development, Astellas Pharma | Erin Kimbrel, PhD – President, Astellas Institute for Regenerative Medicine (AIRM); Head of Cell and Gene Therapy Research, Astellas Pharma | Murtaza Adam, MD – Chair of Clinical Research, Colorado Retina Associates Hosts: John Kitchens, MD, Scott Krzywonos Show Summary Recorded on the final day of ARVO 2026 in Denver, John Kitchens, MD, invites Marci English, MPH, and Erin Kimbrel, PhD, from Astellas to review some of the most significant cell therapy data to emerge in retina in recent years: the phase 1b interim results for ASP7317, an investigational RPE cell therapy that showed functional visual acuity gains in patients with advanced GA. The conversation covers what made earlier cell therapies fail, what's different now, the path to a registration trial, and two additional pipeline programs: ASP2767 (a gene therapy for glaucoma) and ASP2020 (an immune-evasive RPE cell therapy for Stargardt disease). The Vitreoretinal View segment features Moo Adam, MD, who has been performing IV-free vitreoretinal surgery since 2018, now accounting for roughly 70% of his cases. He breaks down patient selection, practical logistics, and why the approach could serve as a bridge to office-based surgery. John and Scott then cover the realities of office-based surgery and speculate what needs to change for retina surgeons to embrace office-based surgery. Hosts: John Kitchens, MD, Scott Krzywonos Topics Covered ASP7317 Phase 1b Interim Results * ASP7317: investigational RPE cell therapy derived from human embryonic stem cells, delivered via subretinal transplantation in advanced GA secondary to AMD * Three dose cohorts with severity stratification; BCVA improvements observed in multiple patients, including gains of 2 lines * GA lesion area stabilized in treated eyes; only 1 month of immunosuppression required * Mechanism: likely a combination of cell replacement, phagocytic debris clearance, and trophic factor secretion * Why earlier RPE transplantation attempts failed: engraftment and immune rejection; advances in differentiation technique and surgical delivery have changed the picture Pipeline & Path Forward * Astellas plans to engage regulators in the coming months with the goal of moving directly to Phase 3; functional BCVA endpoints expected to be central to the registrational design * Complement inhibitors and ASP7317 seen as complementary across the GA spectrum: slowing progression in early disease, potentially restoring function in advanced disease * ASP2020: iPS-derived RPE cell therapy for Stargardt disease, Phase 1 expected in 2026; EVOLVE natural history study ongoing * ASP2767: AAV gene therapy for neuroprotection of retinal ganglion cells in glaucoma; IND filing anticipated shortly Vitreoretinal View: IV-Free Surgery (Moo Adam, MD) * Oral sedation plus sub-Tenon's block replaces IV anesthesia in approximately 70% of Dr. Adam's cases; in practice since 2018 with published safety data * Patient benefits: no fasting, no anesthesiologist copay, no GLP-1 or anticoagulation concerns; appropriate patients can drive themselves home * Patient selection is key, and active patient communication during surgery is essential Office-based Surgery in 2026 * Office-based surgery context: the financial model isn't there yet; no facility fee reimbursement in the office setting, and organized ophthalmology advocacy has stalled Key Takeaways * ASP7317 Phase 1b data showed cell-based therapy led to functional BCVA gains in advanced GA. * Astellas views complement inhibitors and ASP7317 as complementary tools, not competitors, across the GA disease spectrum. * IV-free vitreoretinal surgery is practical, patient-friendly, and already in routine use — but the path to office-based surgery still requires a reimbursement solution.

Clorinda Walley, President & CEO of Good Days, on Patient Assistance Funding | Plus, Image of the Month with Prof. Paulo Stanga: Papillophlebitis on the Silverstone RGB

Guests: Clorinda Walley – President & CEO, Good Days | Prof. Paulo Stanga – Founder & Chief Medical Officer, The Retina Clinic London; Professor of Ophthalmology, UCL Institute of Ophthalmology Show Summary This episode of RetinUp pulls back the curtain on Good Days, one of the most important — and least understood — resources in retina practice. Clorinda Walley, Good Days President & CEO, joins John and Scott to explain how the organization works, how it's funded, who qualifies, and what retina specialists can do to help sustain it. The conversation covers everything from the mechanics of fund allocation to the policy threats currently on Good Days's radar. The episode then moves to the inaugural Image of the Month, featuring Prof. Paulo Stanga, who presents a case of papillophlebitis initially referred as a branch retinal vein occlusion. The case demonstrates how ultra-widefield RGB imaging with the Optos Silverstone RGB changed the clinical picture before the patient ever entered the exam room. Hosts: John Kitchens, MD, and Scott Krzywonos Topics Covered Good Days in 2026 (Clorinda Walley) * What is Good Days? * Types of assistance (copay, premium, and travel support across multiple disease categories) and who is eligible for support * Funding sources for Good Days * How retinal vascular disease assistance operates separately from GA assistance * What happens when a program is funded—and when funding runs out * Good Days’ advocacy in DC and beyond * Getting your patients enrolled in Good Days Image of the Month: Papillophlebitis (Prof. Paulo Stanga) * Case presentation: patient referred for a clinical trial with presumed branch retinal vein occlusion * Ultra-widefield RGB imaging with the Optos Silverstone upon referral * Final diagnosis: papillophlebitis * Clinical workflow advantages of pre-visit imaging Key Takeaways * Good Days is a critical safety net for Medicare patients who cannot afford their retinal treatments, but its programs depend entirely on ongoing donations — funding can close without warning. * Retina specialists can directly support Good Days by getting on the notification list, posting donation signage, and advocating with pharma partners for continued funding. * Retina practice as we know it is supported by Good Days—but Good Days itself is only around as long as their donation base shows up. * Ultra-widefield imaging captured early in an appointment changes clinical workflow: Prof. Stanga's case demonstrates that RGB imaging can redirect a diagnosis before the physician enters the room. * True-color RGB ultra-widefield imaging with swept-source OCT provides a more complete picture of the retina than two-channel systems, particularly at the vitreoretinal interface and in patients with media opacity.

Darius Moshfeghi, MD, on the SOL-1 Study | Plus, Heads-Up 3D Visualization and Medicare Cut Concerns

Show Summary This episode of RetinUp opens with a timely policy discussion between the hosts about proposed Medicare and Medicaid funding cuts, exploring what they could mean for retina practices and their most vulnerable patients. The Vitreoretinal View segment features John Kitchens, MD, sharing his decade-long experience with heads-up 3D visualization. He reviews what makes it transformative for training and surgical outcomes, why widespread adoption has been slower than expected, and what might finally tip the scales. In the main interview, Stanford's Darius Moshfeghi, MD, joins Scott and John to break down the SOL-1 Phase 3 superiority study on Axpaxli (OTX-TKI), Ocular Therapeutix's investigational bioresorbable intravitreal hydrogel incorporating axitinib. He discusses his unique role as an independent rescue monitor, explains the study's novel design, unpacks what the superiority outcome over aflibercept actually means for clinical practice, and previews what the SOL-R study may tell us next. Hosts: John Kitchens, MD, Scott Krzywonos Guests: Darius Moshfeghi, MD – Chief, Retina Division; Professor, Byers Eye Institute, Stanford University School of Medicine Topics Covered SOL-1 Study: Design, Findings & Context (Darius Moshfeghi, MD) * The independent rescue monitor role: what it is, how it worked, and why it was created for SOL-1 * SOL-1’s study design, superiority outcome, and floaters data (and why they were not clinically concerning) * Superiority vs. non-inferiority: implications for labeling, step therapy avoidance, and physician adoption * How retina specialists could integrate Axpaxli into their practice protocols * How SOL-R differs from SOL-1, and what SOL-R might show us Vitreoretinal View: Heads-Up 3D Visualization * Origins of heads-up 3D: TruVision and Alcon NGenuity * Zeiss and Heidelberg heads-up visualization systems * Why John adopted NGenuity early and continues to use it * Key benefits: surgical video quality, fellow training, and real-time coaching * Cost considerations and other reasons why adoption has remained low * The anterior segment opportunity: how cataract surgery economics may drive broader uptake Medicare & Managed Care Policy Concerns * Proposed $200 billion in federal budget cuts and the potential impact on Medicare and Medicaid * Risk of increased step therapy, Avastin-first policies, and tiered drug coverage * Access-to-care concerns for Medicaid patients, particularly at academic medical centers * The difference between traditional Medicare and managed Medicare (Medicare Advantage) * Historical context: past Congressional threats to Medicare reimbursement and how they've played out Key Takeaways * The independent rescue monitor role pioneered in SOL-1 reflects a novel, collaborative approach to adjudicating vision-threatening events in clinical trials. * Physicians will likely adapt AXPAXLI into existing treat-and-extend protocols; SOL-R's more traditional design may generate data that resonates more directly with clinical practice. * SOL-1 is the first superiority study in retina/ophthalmology, demonstrating that a single injection of Axpaxli (Ocular Therapeutix) outperforms aflibercept 2mg (Regeneron) on vision maintenance — with durability extending well beyond current approved dosing intervals. * Heads-up 3D visualization offers meaningful advantages for surgical training and video quality, but high costs for integrated systems and declining surgery center reimbursements continue to limit adoption. * Proposed federal budget cuts to Medicare and Medicaid represent a real threat to retina practices and patient access, particularly for drug coverage and underserved populations.
