“半年一针”药械控释疗法，正重构湿性AMD治疗路径

Core Viewpoint - The article discusses the advancements in the treatment of neovascular age-related macular degeneration (nAMD) through the development of Duravyu, a drug-device combination product by EyePoint, which aims to reduce the treatment burden associated with frequent injections [2][14]. Group 1: Product Development and Clinical Trials - EyePoint's Duravyu has completed patient recruitment for its Phase III LUGANO study within 7 months, enrolling over 400 subjects, marking a significant step towards commercialization [2]. - The preliminary data from the LUGANO trial is expected to be released in mid-2026, with the LUCIA study results anticipated in the second half of 2026 [2]. - Duravyu aims to provide a "six-month injection" treatment regimen, addressing the frequent injection dilemma faced by nAMD patients [2][14]. Group 2: Challenges in Current Treatments - nAMD is a leading cause of severe central vision loss in the elderly, with current anti-VEGF therapies requiring 6 to 12 injections per year, creating a significant treatment burden [3]. - The pharmacokinetic challenges in the posterior segment of the eye necessitate the development of implantable drug delivery systems (IDDS) to maintain stable drug concentrations [3][8]. Group 3: Duravyu's Mechanism and Advantages - Duravyu utilizes EyePoint's proprietary Durasert technology to deliver vorolanib, a multi-target tyrosine kinase inhibitor, through a biodegradable implant [9][12]. - The product is designed to be injected through a standard syringe, simplifying the procedure and reducing the learning curve for healthcare providers [12]. - The release profile of Duravyu can be finely tuned to ensure sustained therapeutic effects while minimizing the need for additional interventions [12][13]. Group 4: Market Implications and Future Directions - The success of Duravyu could significantly impact EyePoint's valuation and provide a model for the future development of sustained-release formulations in ophthalmology [14]. - The article emphasizes the importance of balancing efficacy, safety, and commercial viability in the design of drug-device combination products like Duravyu [14]. - The ongoing evolution of ocular IDDS is expected to lead to innovative solutions that address the treatment burden of nAMD and improve patient outcomes [13][14].
