This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in participants with macular edema due to branch retinal vein occlusion (BRVO).
Study Type
INTERVENTIONAL
Allocation
RANDOMIZED
Purpose
TREATMENT
Masking
TRIPLE
Enrollment
553
Faricimab will be administered by intravitreal (IVT) injection as specified in each treatment arm.
Aflibercept 2 mg will be administered by IVT injection once every 4 weeks (Q4W) from Day 1 through Week 20 (a total of 6 injections).
The sham is a procedure that mimics an intravitreal (IVT) injection, but involves the blunt end of an empty syringe (without a needle) being pressed against the anesthetized eye. It will be administered to participants in both treatments arms at applicable visits to maintain masking.

Part 1: Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye at Week 24
Best Corrected Visual Acuity (BCVA) was measured on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters. The BCVA letter score ranges from 0 to 100 (best score), and a gain in BCVA from baseline indicates an improvement in visual acuity. The Mixed Model of Repeated Measures (MMRM) analysis included the categorical covariates of treatment arm, visit, visit-by-treatment arm interaction, baseline BCVA (continuous), and randomization stratification factors \[baseline BCVA (≥55 and ≤54 letters), and region (U.S. and Canada, Asia, and rest of the world)\] as fixed effects. An unstructured covariance structure was used. Missing data were implicitly imputed by MMRM model assuming missing at random. Treatment policy strategy (i.e., all observed values used) was applied to all intercurrent events (discontinuation of treatment due to AEs or lack of efficacy, use of prohibited therapy). 95% CI is a rounding of 95.03% CI.

The BCVA letter score ranges from 0 to 100 (best score), and a gain in BCVA from baseline indicates an improvement in visual acuity. The weighted percentage of participants was estimated based on the Cochran-Mantel Haenszel (CMH) weights stratified by randomization stratification factors \[baseline BCVA (≥55 and ≤54 letters), and region (U.S. and Canada, Asia, and rest of the world)\]. All observed values were used regardless of the occurrence of an intercurrent event (discontinuation of treatment due to AEs or lack of efficacy, use of prohibited therapy). Missing assessments were imputed by last observation carried forward. 95% CI is a rounding of 95.03% CI.

The core measure includes 25 items that comprise 11 vision-related subscales and 1 item on general health. The composite score ranges from 0 to 100, with higher scores indicating better vision-related functioning. For the MMRM analysis, the model adjusted for the treatment group, visit, visit-by-treatment group interaction, baseline NEI VFQ-25 Composite Score continuous), baseline BCVA score (≥55 and ≤54 letters), and region (U.S. and Canada, Asia, and the rest of the world). Observed NEI VFQ-25 assessments were used regardless of the occurrence of intercurrent events. Missing data were implicitly imputed. Invalid BCVA values were excluded. 95% CI is a rounding of 95.03% CI.

Number of Participants With Anti-Drug Antibodies (ADAs) to Faricimab at Baseline and Post-Baseline During the Study
Anti-drug antibodies (ADAs) against fariciamb were detected in plasma using a validated bridging enzyme-linked immunosorbent assay (ELISA). The number of participants with treatment-emergent ADA-positive samples includes post-baseline evaluable participants with at least one treatment-induced (defined as having an ADA-negative sample or missing sample at baseline and any positive post-baseline sample) or treatment-boosted (defined as having an ADA-positive sample at baseline and any positive post-baseline sample with a titer that is equal to or greater than 4-fold baseline titer) ADA-positive sample during the study treatment period. Treatment-unaffected ADA-positive is a post-baseline sample with a titer that is lower than 4-fold the ADA-positive baseline titer (faricimab arm) or the ADA-positive titer prior to first faricimab injection (aflibercept arm).
