All objectives successfully met: Proof of Concept for Vorolanib in wet AMD Positive Safety Data No ocular SAEs reported No drug-related systemic SAEs reported Ocular AEs - majority mild and to be expected EFFICACY and DURABILITY Positive Efficacy Data Stable VA and OCT Median time to supplemental anti-VEGF: 6 months 76 % rescue-free up to 4 months 53 % rescue-free up to 6 months 41 % rescue-free up to 9 months Clinically significant reduction in treatment burden by 79 % at six mo – 75 % at 8 mo SAFETY DAVIO Take Home Messages: EYP-1901 Phase 1 Clinical Trial Met All Objectives
EYP-1901 – Vorolanib in Bio-erodible Durasert A Novel Approach to Wet AMD Therapy 5 Vorolanib as an Oral Therapy Receptor-binding, small molecule tyrosine kinase inhibitor (TKI) Activity against all isoforms of VEGF and PDGF Oral vorolanib previously studied in a wet AMD ph1 and ph2 programs1,2 Strong efficacy signal but systemic toxicity halted the ph2 study No ocular toxicity noted Jackson et al. JAMA Ophthalmol 2017 Cohen MN et al. Br J Ophthalmol. 2021
Bioerodible Durasert® Platform: injectable, sustained-delivery technology Similar to YUTIQ®, Retisert®, and Vitrasert® Main difference: No polyimide shell ---> Bioerodible Drug release dynamics Initial burst from surface of implant Constant, zero-order kinetic release rate for months Designed for approximately six month or longer efficacy EYP-1901 – Vorolanib in Bioerodible Durasert A Novel Approach to Wet AMD Therapy
