Study population: Patients with age related macular degeneration. Main outcome measures: Three-year cost of therapy when considering medication as well as travel costs and time spent in transit.Results: Based on cost data derived purely from wholesale acquisition cost and projected injection frequency over the first three years of treatment, faricimab is less expensive than ranibizumab and aflibercept by $37,709 and $6359, respectively. Aflibercept is less expensive ranibizumab by $31,350 over the first 3 years of treatment. When considering even small distances traveled by patients, these cost differences grow, amplified at even larger distances: at 25 miles, ranibizumab becomes $38,814 and $32,133 more expensive than faricimab and aflibercept, respectively. Aflibercept becomes $6681 more expensive than faricimab. At 100 miles, ranibizumab becomes $41,502 and $34,038 more expensive than faricimab and aflibercept, respectively. Aflibercept becomes $7464 more expensive than faricimab.Conclusion: Longer acting anti-VEGF therapies may differ not only in their wholesale acquisition cost, but also in the frequency of per label injections and associated clinic visits. Taking into account distance and time cost of travel may contribute to a more holistic view of cost differences among these therapies.Keywords: distance cost, travel cost, longer acting therapy, macular degeneration, anti-VEGF injections
