Abstract
Introduction: Neovascular age-related macular degeneration (nAMD) represents a leading cause of severe visual impairment in individuals over 50 years of age in developed nations. Intravitreal anti-vascular endothelial growth factor (VEGF) injections have become the standard of care for treating nAMD; however, monthly or bimonthly dosing represents significant time and cost burden due to the disease's chronic nature and limited medication half-life.
Areas covered: This review summarizes innovative therapeutics and delivery methods for nAMD. Emerging methods for extended drug delivery include high molar concentration anti-VEGF drugs, intravitreal sustained-release polymers and devices, reservoirs for intravitreal delivery, suprachoroidal delivery of small molecular suspensions and gene therapy biofactories. In addition to VEGF-A, therapies targeting inhibition of VEGF-C and D, the angiopoetin-2 (Ang-2)/Tie-2 pathway, tyrosine kinases, and integrins are reviewed.
Expert opinion: The evolving therapeutic landscape of nAMD is rapidly expanding our toolkit for effective and durable treatment. Recent FDA approvals of faricimab (Vabysmo) and high-dose aflibercept (Eylea HD) for nAMD with potential extension of injection intervals up to four months have been promising developments for patients and providers alike. Further research and innovation, including novel delivery techniques and pharmacologic targets, is necessary to validate the efficacy of developing therapeutics and characterize real-world outcomes, demonstrating promise in expanding treatment durability.
期刊介绍:
Expert Opinion on Biological Therapy (1471-2598; 1744-7682) is a MEDLINE-indexed, international journal publishing peer-reviewed research across all aspects of biological therapy.
Each article is structured to incorporate the author’s own expert opinion on the impact of the topic on research and clinical practice and the scope for future development.
The audience consists of scientists and managers in the healthcare and biopharmaceutical industries and others closely involved in the development and application of biological therapies for the treatment of human disease.
The journal welcomes:
Reviews covering therapeutic antibodies and vaccines, peptides and proteins, gene therapies and gene transfer technologies, cell-based therapies and regenerative medicine
Drug evaluations reviewing the clinical data on a particular biological agent
Original research papers reporting the results of clinical investigations on biological agents and biotherapeutic-based studies with a strong link to clinical practice
Comprehensive coverage in each review is complemented by the unique Expert Collection format and includes the following sections:
Expert Opinion – a personal view of the data presented in the article, a discussion on the developments that are likely to be important in the future, and the avenues of research likely to become exciting as further studies yield more detailed results;
Article Highlights – an executive summary of the author’s most critical points.
