- Kaplan-Meier analyses of the proportion of treated subjects remaining rescue-free through Month 10 [ Time Frame: Baseline through 10 months ]Assessment of the percentage of subjects remaining rescue free at Month 10
- Mean change from baseline in best corrected visual acuity (BCVA) as assessed using the early treatment of diabetic retinopathy (ETDRS) protocol (range, 0 [worst] to 100 [best]) to the average BCVA ETDRS letter score at Months 9 and 10 [ Time Frame: Baseline through 10 months ]Assessment of change in BCVA from baseline compared to the average BCVA scores (ETDRS) at Months 9 and 10
- Mean change from baseline in BCVA (ETDRS letter score) to all visits [ Time Frame: Baseline through 12 months ]
BCVA = best corrected visual acuity; ETDRS = early treatment of diabetic retinopathy
BCVA ETDRS range = 0 (worst) to 100 (best)
Assessment of change in BCVA (ETDRS letter score) from baseline at all visits
- Mean change from baseline in central subfield thickness (CST [μm]) to the average of Months 9 and 10 scores [ Time Frame: Baseline through 10 months ]Assessment of change in CST (μm) measurement from baseline compared to the average OCT CST (μm) measurements at Months 9 and 10
- Mean change from baseline in CST (μm) at all visits [ Time Frame: Baseline through 12 months ]
CST = central subfield thickness
Assessment of change in CST (μm) measurement from baseline at all visits
- Mean change from thickest observed CST (μm) prior to enrollment (pre-enrollment baseline) at all visits [ Time Frame: Screening through 12 months ]
CST = central subfield thickness
Assessment of change from thickest observed CST (μm) prior to enrollment (pre-enrollment baseline) compared to CST (μm) at all visits
- Time to rescue treatment [ Time Frame: Baseline through 12 months ]Assessment of time to rescue treatment over 12 months of treatment
- Mean number of intravitreal injections [ Time Frame: Baseline through 12 months ]Assessment of the mean number of intravitreal injections over 12 months of treatment
- Proportion of subjects with absence of exudation (intra-/sub-retinal fluid/cystoid edema) at Months 9 and 12 of treatment [ Time Frame: Baseline through 12 months ]Assessment of the percentage of subjects with absence of exudation (intra-/sub-retinal fluid/cystoid edema) at Months 9 and 12 of treatment
- Proportion of subjects who gained ≥ 15 ETDRS letters at Months 9 and 12 of treatment [ Time Frame: Baseline through 12 months ]
ETDRS = early treatment of diabetic
Assessment of the proportion of subjects who gained ≥ 15 ETDRS letters at Months 9 and 12 of treatment
- Proportion of subjects who lost ≥ 15 ETDRS letters at Months 9 and 12 of treatment [ Time Frame: Baseline through 12 months ]
ETDRS = early treatment of diabetic
Assessment of the percentage of subjects who lost ≥ 15 ETDRS letters at Months 9 and 12 of treatment
- Proportion of subjects with BCVA worse than 20/200 (Snellen equivalent) at Months 9 and 12 of treatment [ Time Frame: Baseline through 12 months ]
Assessment of the percentage of subjects with BCVA worse than 20/200 (Snellen equivalent) at Months 9 and 12 of treatment
A vision score of 20/20 is considered normal. A vision score of 20/200 is considered legally blind.
