EYP-1901 - Potential Twice a Year Anti-VEGF Treatment 8 | EYEPOINT PHARMACEUTICALS PIPELINE Our goal is nothing short of transforming the treatment of wet AMD, diabetic retinopathy, and retinal vein occlusion
PIPELINE EYP-1901 Opportunity to transform the treatment of wet AMD The need... Currently, wet AMD patients often lose vision despite anti-VEGF therapy due to undertreatment The EYP-1901 solution... Potential twice yearly in-office injection of anti-VEGF therapy Anti-VEGF therapy (vorolanib) delivered via intravitreal injection using bioerodible Durasert Sustained, stable release may lead to better visual outcomes through steady receptor blocking 9 | EYEPOINT PHARMACEUTICALS VEGF-vascular endothelial growth factor
Real world need... today's wet AMD treatments still result in vision loss over time PIPELINE EYP-1901 Adjusted Mean Change From Baseline in VA Letter Score 3 6 12 Month 12 p=0.67† Aflibercept Ranibizumab 1.52 1.01 -0.19 1.24 0.71 -0.30 Follow-up (Month) Lotery et al., Eye (2017) 31, 1697–1706 RETROSPECTIVE STUDY OF 3350 RANIBIZUMAB AND 4300 AFLIBERCEPT TREATMENT-NAIVE EYES WITH WET AMD 4 3 2 1 0 -1 -2 -3 -4 0 10 | EYEPOINT PHARMACEUTICALS
EYP-1901 Intravitreal delivery of vorolanib using a bioerodible formulation of Durasert® Vorolanib Tyrosine kinase inhibitor (TKI) studied as an oral therapy for wet AMD through Phase 2 with strong clinical signal and no significant ocular adverse events Blocks all 3 isoforms of VEGFR, the main driver of the proliferation of blood vessels that are the hallmark of wet AMD PIPELINE EYP-1901 The EYP-1901 solution 11 | EYEPOINT PHARMACEUTICALS VEGFR- vascular endothelial growth factor receptor

A potent inhibitor of VEGFR Vorolanib blocks VEGFR2 at the same level as sunitinib, a proven anti-VEGF therapy The inhibitor constant (Ki) of sunitinib for VEGFR is reported to be low (5 ng/mL), an indication of strong inhibition. Since Ki is related to IC50, similar inhibition Ki is expected for vorolanib. PIPELINE EYP-1901 13 | EYEPOINT PHARMACEUTICALS IC50 – half maximal inhibitory concentration Head-to-head study completed by Tyrogenix
Oral vorolanib clinical results – Phase 1 Demonstrated clinical activity in wet AMD Phase 1 trial design Open label, 24 weeks, dose escalation, no control, oral delivery; 80% of eyes enrolled previously treated; 4 eyes treatment naïve N=35; 25 completers Phase 1 results BCVA was maintained to within 4 letters of baseline at the 24-week endpoint, or improved in all but 1 participant 60% (15/25) of patients required no rescue injection while on oral vorolanib therapy Excluding the 50 mg low dose, 72% of completers required no Anti-VEGF injection through the duration of the study (6 months) Mean OCT thickness in completers was reduced by -50 +/- 97 µm; Mean OCT thickness in treatment-naïve patients was reduced by ~80 µm PIPELINE EYP-1901 14 | EYEPOINT PHARMACEUTICALS OCT – ocular coherence tomography Study performed by Tyrogenex
Oral vorolanib clinical activity in wet AMD Phase 2 trial Less rescue vs placebo for all doses with no ocular toxicity PIPELINE EYP-1901 Strict pre-defined rescue criteria with anti-VEGF therapy Any increase in fluid on OCT compared to screening visit 2 (~14 days after an IVT injection) New or increased macular hemorrhage by fundus photography In the placebo group, 12.5% of subjects with unilateral disease at baseline developed exudative AMD in their fellow eyes by 52 weeks, compared with 3.8% (1/26), 0%(0/27) and 0%(0/23) in the 50 mg, 100 mg, and 200 mg groups, respectively. * Normalized for number of months on study Study performed by Tyrogeix 15 | EYEPOINT PHARMACEUTICALS
