Outcomes

Primary Outcome Measures

Change From Baseline in Best Corrected Visual Acuity (BCVA) (Letters Read) at Week 48 - Study Eye
BCVA (with spectacles or other visual corrective devices) was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) testing at 4 meters and reported in letters read correctly. Baseline was defined as the last measurement prior to first treatment. An increase (gain) in letters read from the baseline assessment indicates improvement. One eye (study eye) contributed to the analysis.

Secondary Outcome Measures

Average Change From Baseline in BCVA (Letters Read) Over the Period Week 36 Through Week 48 - Study Eye
BCVA (with spectacles or other visual corrective devices) was assessed using ETDRS testing at 4 meters and reported in letters read correctly. For each subject, this endpoint was defined as the average of the changes from baseline to Weeks 36, 40, 44, and 48. Baseline was defined as the last measurement prior to first treatment. An increase (gain) in letters read from the baseline assessment indicates improvement. One eye (study eye) contributed to the analysis.
Proportion of Subjects With Positive q12 (Every 12 Weeks) Treatment Status at Week 48
Positive q12 treatment status was defined as IVT injections per planned dosing regimen (one injection every 12 weeks "q12w", after the initial three loading injections every 4 weeks "q4w"). A disease activity assessment (DAA) was performed at pre-specified visits (Weeks 16, 20, 28, 32, 40, 44) to identify q8w (one injection every 8 weeks) need. The estimate for the proportion of subjects with a positive q12w status at Week 48 were derived from Kaplan-Meier time to event analyses for the event of first q8w need, applying event allocations (in case of lack of efficacy and/or lack of safety=efficacy/safety approach) and censoring as described in the SAP. Censored subjects were considered to be not anymore under risk for a q8 need identification at later visits. Corresponding 95% Confidence Intervals (CIs) were derived from the LOGLOG transformation. No hypothesis testing was performed. This outcome measure was pre-specified for brolucizumab 3mg and 6 mg arms only.

Change From Baseline in Visual Function Questionnaire (VFQ-25) Composite Score at Week 24, Week 48, Week 72, and Week 96
The National Eye Institute Visual Function Questionnaire-25 (VFQ-25) is a validated questionnaire that collects 25 vision-targeted responses from age-related macular degeneration (AMD) subjects. The 25 questions pertain to global vision rating (1), difficulty with near vision activities (3), difficulty with distance vision activities (3), limitations in social functioning due to vision (2), role limitations due to vision (2), dependency on others due to vision (3), mental health symptoms due to vision (4), driving difficulties (3), limitations with peripheral (1) and color vision (1), and ocular pain (2). Each response is converted to a 0 to 100 sub-scale, with the lowest and highest possible scores set at 0 and 100 points, respectively. The overall composite score (0 to 100) is obtained by averaging the 25 sub-scale scores. A high score represents better functioning.
Percentage of Subjects With Induced or Boosted Anti-drug Antibody (ADA) Status at Week 48 (Brolucizumab Only)

ADA induced was defined as ADA negative at predose with postdose titer value greater than or equal to a titer of 30 at any timepoint. ADA boosted was defined as ADA positive at predose with postdose titer values that increased by at least two dilutions (9-fold) from their respective predose value at any time point. Hypothesis testing not pre-specified.

5. Study Description

Brief Summary
The purpose of this study is to compare brolucizumab (RTH258) ophthalmic solution for intravitreal (IVT) injection at two dosage levels (3 mg and 6 mg) to aflibercept ophthalmic solution for IVT injection (2 mg) in subjects with untreated active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) in the study eye.
Detailed Description
Subjects were randomized to brolucizumab 3 mg, brolucizumab 6 mg,and aflibercept 2 mg in a 1:1:1 ratio. Subjects in all treatment arms received 3 monthly loading doses (Day 0, Week 4 and Week 8), followed by a maintenance regimen, until the end of the study (Week 96/Exit). All subjects attended pre-specified visits every 4 weeks. Subjects in the brolucizumab 3 mg and brolucizumab 6 mg arms followed a q12w/q8w maintenance regimen. Within the q12w/q8w regimen, the initial treatment after the loading phase was q12w (1 injection every 12 weeks). If disease activity was identified by the masked investigator at any of the disease activity assessments, dosing was adjusted to q8w (1 injection every 8 weeks) ("q12w/q8w regimen"). Once subjects were adjusted to the q8w interval, they stayed on that interval until the end of the study. Subjects in the aflibercept 2 mg arm followed a q8w maintenance regimen until the end of the study. Results reported up to Week 48 are based on the database locked for the primary analysis at Week 48. Results reported after Week 48 are based on the database locked at the end of study (final analysis).

Description
Positive q12 treatment status was defined as IVT injections per planned dosing regimen (one injection every 12 weeks "q12w", after the initial three loading injections every 4 weeks "q4w"). A disease activity assessment (DAA) was performed at pre-specified visits (Weeks 16, 20, 28, 32, 40, 44) to identify q8w (one injection every 8 weeks) need. The estimate for the proportion of subjects with a positive q12w status at Week 48 were derived from Kaplan-Meier time to event analyses for the event of first q8w need, applying event allocations (in case of lack of efficacy and/or lack of safety=efficacy/safety approach) and censoring as described in the SAP. Censored subjects were considered to be not anymore under risk for a q8 need identification at later visits. Corresponding 95% Confidence Intervals (CIs) were derived from the LOGLOG transformation.

Change From Baseline in Visual Function Questionnaire (VFQ-25) Composite Score at Week 24, Week 48, Week 72, and Week 96
Description
The National Eye Institute Visual Function Questionnaire-25 (VFQ-25) is a validated questionnaire that collects 25 vision-targeted responses from age-related macular degeneration (AMD) subjects. The 25 questions pertain to global vision rating (1), difficulty with near vision activities (3), difficulty with distance vision activities (3), limitations in social functioning due to vision (2), role limitations due to vision (2), dependency on others due to vision (3), mental health symptoms due to vision (4), driving difficulties (3), limitations with peripheral (1) and color vision (1), and ocular pain (2). Each response is converted to a 0 to 100 sub-scale, with the lowest and highest possible scores set at 0 and 100 points, respectively. The overall composite score (0 to 100) is obtained by averaging the 25 sub-scale scores. A high score represents better functioning.
