Summary of Key Points from the Oculis Holding (OCS) Fireside Chat Industry Overview - The discussion revolves around advancements in therapies for retinal disorders, particularly focusing on dry age-related macular degeneration (AMD), Stargardt disease, retinitis pigmentosa, and diabetic macular edema (DME) [1][2][3][4][5]. Core Insights and Arguments Unmet Medical Needs - There is a pressing need for effective treatments for retinal disorders, especially for conditions like dry AMD, geographic atrophy (GA), and retinitis pigmentosa [3][4]. - Gene therapy has shown promise in treating inherited retinal diseases, with Luxturna being a notable example for RPE65 mutations [4]. Clinical Endpoints and Biomarkers - Key clinical endpoints for evaluating therapies include best corrected visual acuity, contrast sensitivity, and anatomical biomarkers assessed through OCT imaging [5][6][7]. - The ellipsoid zone is highlighted as a critical marker for photoreceptor health, with advancements in OCT technology enhancing its assessment [56]. Adoption Factors for Novel Therapies - Factors influencing the adoption of new retinal therapies include ease of administration, patient compliance, and payer reimbursement challenges [9][10][11][12]. - Non-invasive treatments, such as topical eye drops, are favored due to their convenience compared to invasive procedures like intravitreal injections [41][42]. Specific Drug Mechanisms and Developments - **Elamipretide** targets mitochondrial dysfunction in dry AMD, aiming to protect at-risk photoreceptors and potentially improve vision [14][15][16][20]. - **Telarabine** is designed to reduce toxic bisretinoids in Stargardt disease and GA, addressing a significant unmet need as there are currently no approved therapies for Stargardt disease [23][24][30]. - **MCO-10** is a mutation-agnostic gene therapy for retinitis pigmentosa and Stargardt disease, utilizing optogenetics to restore vision by targeting remaining bipolar cells [32][33][34]. Regulatory and Commercial Considerations - The FDA has provided feedback indicating that targeting mitochondria to reduce photoreceptor loss is an acceptable strategy for dry AMD treatment [18][19]. - The breakthrough therapy designation for telarabine is expected to facilitate a faster regulatory pathway, with an NDA submission anticipated in the first half of the following year [31][83]. Important but Overlooked Content - The socioeconomic factors affecting patient compliance and access to treatments are significant, with many patients facing logistical challenges in attending frequent treatment sessions [12][11][52]. - The potential for combination therapies, where different mechanisms may work synergistically, is acknowledged but requires further exploration [70][74]. Conclusion - The ongoing developments in retinal therapies present significant opportunities for addressing unmet medical needs in various retinal disorders. The focus on patient-centric approaches, including non-invasive delivery methods and robust clinical endpoints, is crucial for the successful adoption of these therapies in clinical practice [80][81].
