Official title: A Twelve-Month, Randomized, Double-Masked, Multicenter, Phase III, Two-Arm Study Comparing the Efficacy and Safety of Brolucizumab 6 mg Versus Aflibercept in Chinese Patients With Neovascular Age-Related Macular Degeneration
To compare brolucizumab to aflibercept in Chinese patients with untreated active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD)
Read the detailed description
This was a randomized, double-masked, multicenter, parallel-group, active-controlled study. The study included 14 scheduled visits over 48 weeks. After confirmation of eligibility at baseline, participants were randomized in a 1:1 ratio to one of the 2 treatment arms:
- Brolucizumab 6 mg: 3 monthly intravitreal injections of brolucizumab 6 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 12 weeks (q12w regimen) or 8 weeks (q8w) up to Week 40 or Week 44, depending on disease activity status.
- Aflibercept 2 mg: 3 monthly intravitreal injections of aflibercept 2 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 8 weeks (q8w) up to Week 40. Disease activity assessments (DAAs) were conducted by the masked investigator for both treatment arms at Weeks 16, 20, 32 and 44 to determine the regimen of brolucizumab arm (i.e., q12w or q8w).
- Being tested

Measured: Baseline, Week 48
Secondary outcomes (50)
Average Change From Baseline Over the Period of Week 36 to Week 48 in Best-Corrected Visual Acuity in Study Eye
BCVA was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts.
Visual function of the study eye was assessed using the ETDRS protocol. Participants with a BCVA ETDRS letter score between 78 and 23 ETDRS letters (inclusive) at Screening and Baseline in the study eye were included.
Min and max possible scores are 0-100 respectively. A higher score represents better functioning.
Last observation carried forward (LOCF) was used for the imputation of missing values.
Measured: Baseline, over the period Week 36 to Week 48
q12w Treatment Status at Week 48 (for Subjects Randomized to Brolucizumab 6 mg Only) - Probability
The estimate for the proportion of participants with a positive q12w treatment status was derived from Kaplan-Meier time-to-event analyses for the event "first q8w-need", applying a "q8w-need" allocation in case of missing or confounded data attributable to lack of efficacy and/or lack of safety for the purpose of analysis. The proportion of participants with a positive q12w treatment status was derived as follows according to the "sufficient efficacy and safety" approach: the q8w-need assessment was imputed as "Yes" at the disease activity assessment (DAA) visit following early treatment/study discontinuation due to lack of efficacy and /or lack of safety of the study treatment (applicable to both missing and non-missing DAAs).
Measured: Week 44
q12w Treatment Status at Week 48 Within the Subjects With no q8w Need During the First q12w Cycle (Week 16 and Week 20) (for Subjects Randomized to Brolucizumab 6 mg Only) - Probability
The estimate for the proportion of participants with a positive q12w treatment status was derived from Kaplan-Meier time-to-event analyses for the event "first q8w-need", applying a "q8w-need" allocation in case of missing or confounded data attributable to lack of efficacy and/or lack of safety for the purpose of analysis.
The analysis of "q12w treatment status within the participants randomized to brolucizumab 6 mg and with no q8w need during the first q12w cycle" was based on the subset of FAS participants randomized to brolucizumab 6 mg with no identified q8w-need at Week 16 and Week 20.
Measured: Week 44
Number (%) of Participants With q8w Treatment Need as Assessed by the Investigator at First Disease Activity Assessment (DAA) Visit
For both arms, the treatment was initiated with 3 monthly injections at Weeks 0, 4 and 8 (loading phase). Week 12 was scheduled as a "no injection visit" for both arms per protocol. Therefore, by Week 16, the planned treatment exposure was identical between the treatment arms, allowing a matched comparison of brolucizumab and aflibercept up to 8 weeks after loading.
Measured: Week 16

Items within each subscale are averaged together to create 12 subscale scores. An overall composite score was calculated by averaging vision-targeted subscale scores, excluding the general health rating question. All items are scored so that a high score represents better visual functioning.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
To compare brolucizumab to aflibercept in Chinese patients with untreated active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD)
Detailed description
This was a randomized, double-masked, multicenter, parallel-group, active-controlled study. The study included 14 scheduled visits over 48 weeks. After confirmation of eligibility at baseline, participants were randomized in a 1:1 ratio to one of the 2 treatment arms:
- Brolucizumab 6 mg: 3 monthly intravitreal injections of brolucizumab 6 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 12 weeks (q12w regimen) or 8 weeks (q8w) up to Week 40 or Week 44, depending on disease activity status.
- Aflibercept 2 mg: 3 monthly intravitreal injections of aflibercept 2 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 8 weeks (q8w) up to Week 40. Disease activity assessments (DAAs) were conducted by the masked investigator for both treatment arms at Weeks 16, 20, 32 and 44 to determine the regimen of brolucizumab arm (i.e., q12w or q8w).

Primary outcome
Change From Baseline at Week 48 in Best-Corrected Visual Acuity in Study Eye
Time frame: Baseline, Week 48
BCVA was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts. Visual function of the study eye was assessed using the ETDRS protocol. Participants with a BCVA ETDRS letter score between 78 and 23 ETDRS letters (inclusive) at Screening and Baseline in the study eye were included. Min and max possible scores are 0-100 respectively. A higher score represents better functioning. Last observation carried forward (LOCF) was used for the imputation of missing values.
