Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

|---|---|---|---|
| Primary | Change From Baseline in BCVA Measured by the ETDRS Letter Score at Week 36 | At Week 36 | BCVA: Best-Corrected Visual Acuity; ETDRS: Early Treatment Diabetic Retinopathy Study; ETDRS letter score (ranging from 0 to 100 letters). A higher letter score means a better outcome (better visual acuity) |
| Secondary | Number of Active Injections From Baseline to Week 64 | From baseline to Week 64 | Active injections refer to the number of injections that were actually administered, as opposed to the number of planned injections. |
