Sozinibercept, a Proprietary VEGF-C/D “Trap” Inhibitor, Has the Potential to Address the Limitations of Anti-VEGF-A Therapies The Problem The Solution Wet AMD is a multi-factorial disease. Treatment with VEGF-A inhibitors upregulates VEGF-C/D, driving angiogenesis and vascular permeability. When used in combination with any VEGF-A inhibitor, sozinibercept completely blocks VEGFR-2 and VEGFR-3 signaling. 1 Faricimab also has inhibitory effect on Ang-2. a Bevacizumab is used ’off-label’ for the treatment of neovascular (wet) AMD Faricimab (Vabysmo®)1 SOZINIBERCEPT

The Phase 3 clinical trial masked data are incomplete and subject to additional analysis once unmasked. There is no assurance that standard of care monotherapy in our Phase 3 clinical trials will yield similar results to our prior clinical trials or previously published clinical trials with anti-VEGF-A monotherapies. As a result, there can be no assurance that topline results for sozinibercept from the Phase 3 clinical trial, if completed, will be consistent with results from masked data available to date. Pooled safety analysis of 399 patients for completed sozinibercept trials Data Monitoring Committee (“DMC”) regularly reviews data from ongoing Phase 3 COAST and ShORe studies Safety data from our completed sozinibercept trials show sozinibercept combination therapy has a safety and tolerability profile comparable to standard of care anti-VEGF-A monotherapy.

Phase 3 Clinical Program Is Informed by Phase 2b Results and Optimized for Success Hierarchical primary analysis first conducted in the high-responding occult and minimally classic population (RAP absent), followed by total patient population Two robust pivotal trials studying sozinibercept in combination with Eylea® and Lucentis® in treatment naïve patients with wet AMD Phase 3 designed to support broad label for use in combination with any VEGF-A inhibitor for all wet AMD patients (treatment naïve and prior treated)
Phase 3 Wet AMD Trials COAST and ShORe Are Well Advanced Topline Data Anticipated for COAST in Early 2Q CY 2025 and ShORe in Mid-CY2025 Design Multi-center, double-masked, randomized (1:1:1), sham control Treatment naïve wet AMD patients Regulatory Quality ~90% power, 5% type I error rate Sample Size COAST n=998; ShORe n=986 Comparators 2 mg Eylea® q8w (COAST) & 0.5 mg Lucentis® q4w (ShORe)
Phase 3 Primary and Secondary Endpoints Primary Efficacy Endpoint at Week 52 to Support BLA Submission Primary Endpoint Key Secondary Endpoints (Baseline to Week 52) Mean change from baseline in BCVA at week 52 Proportion of participants gaining ≥15 letters Proportion of participants gaining ≥10 letters Change in choroidal neovascularization area Proportion of participants with absence of both sub-retinal fluid and intra-retinal cysts
