Patients diagnosed ≤1 year with ≤2 prior αVEGF injections Highly positive, statistically non-inferior DAVIO 2 results despite tough to treat population Average of 10 injections per year prior to enrollment Aflibercept arm (q8w) had nearly 25% supplementation rate despite receiving on-label injections Supplement-free eyes did the best visually and, in those eyes, DURAVYU performed numerically better than aflibercept visually In DAVIO 2, eyes that were pseudo naïve1 had fewer supplements than the overall cohort We believe the inclusion of treatment naive patients not only expands the potential patient population but also increases the probability of success
