Slide 19: Cataract imbalance not observed with monthly dosing in DAYLIGHT
Cataract imbalance in GLEAM and GLIMMER not observed with monthly dosing in DAYLIGHT, which indicates that exposure or accumulation does not play a significant role GLEAM + GLIMMER DAYLIGHT DAZZLE BEACON (DME) (wAMD) (wAMD) (RVO) Duration of Follow-Up 64 Weeks 48 Weeks 52 Weeks 48 Weeks Tarcocimab A
Slide 20: Tarcocimab has a higher cataract incidence. What do we believe it is related to?
Tarcocimab has a higher cataract incidence. What do we believe it is related to? • The triggering insult seems to be localized to the back of the lens. A progressive posterior subcapsular cataract is a noticeable finding. Week 32 Week 44 Week 48 Inferotemporal injection Diabetic patient treated with
Slide 21: Cataract incidence seems specific to diabetic patients with retinopathy
Tarcocimab has a higher cataract incidence. What do we believe it is related to? • Seems to be highly specific to diabetic patients with diabetic eye disease (retinopathy). ‒ wAMD patients receiving 12 monthly doses in DAYLIGHT over one year did not show an increased cataract incidence. ‒ RVO patien
Slide 22: Local insult in a susceptible environment
The higher cataract incidence seen with tarcocimab seems to be a relationship between a local insult in a susceptible environment Diabetic patients with retinopathy are the susceptible population The lens in diabetics is under metabolic duress The posterior lens capsule is more fragile in diabetics
Slide 23: Gel-like consistency and higher cataract incidence. Can it be solved?
The gel-like consistency of tarcocimab results in a higher cataract incidence in diabetic patients with retinopathy. Can it be solved? An improved formulation for all antibody biopolymer conjugates is a plausible solution Improved injection procedure (decreased injection time and force needed) Impro
Slide 24: What do we believe the cataract incidence is not related to?
Tarcocimab has higher cataract incidence. What do we believe it is not related to? Patient Characteristics Injectors Animal Toxicology Not related to Not related to Not related to age Not site related Not seen in non- mid-term diabetes duration Mean (SD) age at baseline was The cataract events occur
Slide 25: Conclusions
Conclusions GLEAM and GLIMMER did • The initial matched phase demonstrated robust efficacy not meet the primary • Individualized dosing with tarcocimab maintained initial BCVA gains, with half or more of endpoint the patients consistently on 6-month dosing Tarcocimab continues to • 1/2 of patients a
