European Health Technology Assessment Considerations Related to Gene Therapies in Eyecare: The Neovascular Age-Related Macular Degeneration Example

Gene therapies that induce the body to produce therapeutic anti-vascular endothelial growth factor (anti-VEGF) proteins are an emerging topic related to neovascular age-related macular degeneration (nAMD). Continuous delivery of anti-VEGF protein directly to the target tissue offers the possibility of lifelong efficacy without the need for repeated and frequent eye injections. This novel approach could revolutionize patient management through optimizing clinical outcomes while simplifying service delivery. However, such gene therapies are anticipated to face unique challenges related to patients’ access and health technology assessment (HTA), and their integration into real-world eyecare practices. This article presents key elements raised at the European Access Academy (EAA) Fall convention (held in Rome in October 2024) regarding anticipated HTA challenges for gene therapies in nAMD. The important role of HTA and policymakers in ensuring that emerging gene therapies are accessible to all eligible patients is also highlighted. This article mainly focuses on the need for a fit-for-purpose EU HTA framework to address the widely varying utilization of standard of care in nAMD clinical practice, and to incorporate considerations about the long-term durability of gene therapies in nAMD. The importance of integrating real-world evidence (RWE) into the EU HTA framework is also discussed.
