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

    MAY 14

    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 AMDThree dose cohorts with severity stratification; BCVA improvements observed in multiple patients, including gains of 2 linesGA lesion area stabilized in treated eyes; only 1 month of immunosuppression requiredMechanism: likely a combination of cell replacement, phagocytic debris clearance, and trophic factor secretionWhy 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 designComplement inhibitors and ASP7317 seen as complementary across the GA spectrum: slowing progression in early disease, potentially restoring function in advanced diseaseASP2020: iPS-derived RPE cell therapy for Stargardt disease, Phase 1 expected in 2026; EVOLVE natural history study ongoingASP2767: 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 dataPatient benefits: no fasting, no anesthesiologist copay, no GLP-1 or anticoagulation concerns; appropriate patients can drive themselves homePatient 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.

  2. 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

    APR 30

    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 supportFunding sources for Good DaysHow retinal vascular disease assistance operates separately from GA assistance What happens when a program is funded—and when funding runs outGood Days’ advocacy in DC and beyondGetting 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 occlusionUltra-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.

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

    APR 16

    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-1SOL-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 adoptionHow retina specialists could integrate Axpaxli into their practice protocolsHow 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 NGenuityZeiss and Heidelberg heads-up visualization systemsWhy John adopted NGenuity early and continues to use itKey benefits: surgical video quality, fellow training, and real-time coachingCost considerations and other reasons why adoption has remained lowThe 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 MedicaidRisk of increased step therapy, Avastin-first policies, and tiered drug coverageAccess-to-care concerns for Medicaid patients, particularly at academic medical centersThe 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.

    MAR 5

    RetinUp Mailbag – Cash Pay Models, Emerging Therapies, and Tech Adoption During Reimbursement Reductions

    Hosts: John Kitchens, MD Scott Krzywonos Show SummaryIn this special RetinUp Mailbag episode, John Kitchens and Scott Krzywonos answer listener questions from retina specialists around the country about three issues: cash-pay diversification, the future of emerging therapies in light of payer realities, and how practices can realistically adopt expensive new technology as reimbursements decline. The conversation explores whether concierge retina models could emerge in certain markets, how insurers may respond to high-cost innovations like gene therapy and tyrosine kinase inhibitors, and what practical frameworks practices use when deciding whether to invest in new surgical or imaging equipment. Throughout the episode, a central theme emerges: innovation in retina continues to accelerate, but reimbursement pressure is forcing practices to rethink business models, technology adoption, and long-term sustainability. Topics Covered Cash-Pay Diversification in RetinaListener question from Jed Assam, MD (VRA Vision, Sioux Falls, South Dakota) Whether concierge retina could work, and whether VIP-style care models might translate to retina practicesPotential cash-pay services such as photobiomodulation (PBM) therapyOperational considerations for scheduling concierge visits separately from standard clinic flowGeographic limitations for cash-pay models in smaller markets Future Therapies and Insurance CoverageListener question from Deepak Sambhara, MD (Eye Clinic of Wisconsin, Wausau, Wisconsin) How payers may respond to upcoming therapies such as tyrosine kinase inhibitors and gene therapyThe likelihood of step therapy policies changingPricing challenges for long-duration treatmentsEconomic implications of one-time gene therapy approaches Technology Adoption in an Era of Declining ReimbursementListener question from Priya Vakharia, MD (Retina Vitreous Associates of Florida, Tampa, Florida) How practices decide when to adopt new surgical technologyCost pressures from declining surgical reimbursementEvaluating investments in surgical and imaging equipment The potential role of AI-driven analysis in improving efficiency and clinical decision-making Key TakeawaysConcierge-style retina care may be viable in affluent metropolitan markets but remains niche.Insurance economics will strongly influence how quickly new therapies reach patients.Practices increasingly rely on ROI analysis and efficiency gains when deciding whether to adopt new technologies.Artificial intelligence may help practices manage growing data complexity, though its financial model remains uncertain.
