UBX1325 Phase 2 ENVISION Study in Patients with Neovascular AMD Additional Insights from Secondary Analysis UBX1325 monotherapy did not achieve non-inferiority through 24 weeks due, in part, to an unexpected 3.5 letter gain in the anti-VEGF control arm UBX1325 maintained visual acuity in patients with ongoing active disease through 24 weeks with less than one letter mean decrease from baseline 52% of UBX1325-treated patients did not require anti-VEGF treatment through 24 weeks UBX1325 was well tolerated with no instances of intraocular inflammation A single dose of run-in aflibercept may not have been sufficient to get patients entering study to anti-VEGF BCVA plateau UBX1325 may be more effective in patients with longer disease duration who may have greater senescence burden Phase 2 ENVISION Part A Study Data Highlights

Summary of UBX1325 ENVISION Phase 2 Study in nAMD Was generally well tolerated with no intraocular inflammation Maintained visual acuity through 24 weeks in patients with active disease; there was a 3.5 letter gain in aflibercept arm at 2 weeks and non-inferiority to aflibercept was not met May have greater treatment effect in patients with AMD diagnosis greater than two years based on post-hoc assessments Allowed 52% of patients to avoid anti-VEGF treatment for at least 6 months @Vicki Can we make the this slide a little more punchy/less flat?
