Clinical Trial Summary

The purpose of this study was to evaluate the efficacy and safety of brolucizumab in treatment of patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO).

Description:

The study included Screening Period (Day -28 to Day -1), double-masked treatment period (Day 1 to Week 72), and post-treatment follow-up period (Week 72 to Week 76). Treatment visits were scheduled in 4-week intervals. After 6 initial monthly injections of brolucizumab or aflibercept (loading phase), subjects entered a one-year individualized flexible treatment (IFT) phase. During the IFT phase, an assessment of disease stability was performed at each monthly visit and subjects received either an active or a sham injection. Treatment with active was interrupted when disease stability was reached.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Best-corrected Visual Acuity (BCVA) at Week 24	BCVA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at an initial testing distance of 4 meters.; Min and max possible scores are 0-100 letters read respectively. A higher score represents better visual functioning.; Missing and censored BCVA values were imputed by Last observation carried forward (LOCF) as the primary approach. Observed values from both scheduled and unscheduled post-baseline visits were used for the LOCF imputation. For subjects with no post-baseline BCVA value, the baseline value was carried forward.	Baseline, Week 24
Secondary	Change From Baseline in BCVA Averaged Over Week 40 to Week 52	An average BCVA over week 40 to week 52 was calculated. BCVA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at an initial testing distance of 4 meters.; Min and max possible scores are 0-100 letters read respectively. A higher score represents better visual functioning.	Baseline, Week 40 to Week 52
Secondary	Change From Baseline in BCVA Averaged Over Week 64 to Week 76	An average BCVA over week 64 to week 76 was calculated. BCVA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at an initial testing distance of 4 meters.; Min and max possible scores are 0-100 letters read respectively. A higher score represents better visual functioning.	Baseline, Week 64 to Week 76
Secondary	Change From Baseline in BCVA by Visit up to Week 76	BCVA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at an initial testing distance of 4 meters. Min and max possible scores are 0-100 letters read respectively. A higher score represents better visual functioning.	Baseline and every 4 weeks from baseline up to Week 76
Secondary	Proportion of Participants With a Gain = 5, 10 and 15 Letters in BCVA by Visit Compared to Baseline	The summary by visit was conducted based on the BCVA observed from each of the corresponding visits.; BCVA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at an initial testing distance of 4 meters.; Min and max possible scores are 0-100 letters read respectively. A higher score represents better visual functioning.; Every 5 letters represents 1 line of vision on the reading chart.	Baseline and every 4 weeks from baseline up to Week 76
Secondary	Proportion of Participants With a Loss = 5, 10 and 15 Letters in BCVA by Visit Compared to Baseline	The summary by visit was conducted based on the BCVA observed from each of the corresponding visit.; BCVA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at an initial testing distance of 4 meters.; Min and max possible scores are 0-100 letters read respectively. A higher score represents better visual functioning.; Every 5 letters represents 1 line of vision on the reading chart.	Baseline and every 4 weeks from baseline up to Week 76
Secondary	Change From Baseline in CSFT Averaged Over Week 40 to Week 52	Change from baseline in central subfield thickness (CSFT) averaged over Week 40 to Week 52, measured in µm by Spectral Domain Optical Coherence Tomography (SD-OCT)	Baseline, Week 40 to Week 52
Secondary	Change From Baseline in CSFT Averaged Over Week 64 to Week 76	Change from baseline in central subfield thickness (CSFT) averaged over Week 64 to Week 76, measured in µm by Spectral Domain Optical Coherence Tomography (SD-OCT)	Baseline, Week 64 to Week 76
Secondary	Change From Baseline in CSFT by Visit up to Week 76	Change from baseline in central subfield thickness (CSFT) measured in µm by Spectral Domain Optical Coherence Tomography (SD-OCT)	Baseline, and every 4 weeks from baseline up to Week 76
Secondary	Proportion of Subjects With Presence of Retinal Fluid (Intra- and/or Subretinal Fluid) in the Study Eye by Visit up to Week 76	Presence of retinal fluid (intra- and/or subretinal fluid) assessed by Spectral Domain Optical Coherence Tomography (SD-OCT)	Every 4 weeks from week 4 up to Week 76
Secondary	Proportion of Subjects With a CSFT < 300 µm for the Study Eye by Visit up to Week 76	Central subfield thickness (CSFT) is measured in µm by Spectral Domain Optical Coherence Tomography (SD-OCT)	Every 4 weeks from week 4 up to Week 76
Secondary	Number of Injections Between Week 24 and Week 52 and Between Week 24 and Week 72	Number of administered injections during the individualized flexible treatment (IFT) period, between Week 24 and Week 52 and between Week 24 and Week 72 are presented	Week 24 to Week 52 and Week 24 to Week 72
Secondary	Time to Recurrence After Week 20 and up to Week 76	Recurrence is defined as the need for injection while showing a lack of disease stability for the first time after Week 20 and up to Week 76.; For subjects with recurrence after the Week 20 visit, time-to-event is calculated as (first time with the lack of disease stability - the injection date on Week 20 visit + 1). For subjects without recurrence after Week 20, the censoring time will be calculated as (last visit with disease stability assessment - the injection date on Week 20 visit + 1).	Week 20 to Week 76
Secondary	Number of Subjects With Ocular and Non-ocular AEs up to Week 52 and Week 76	Number of subjects with at least one ocular or non-ocular Adverse Events (AEs).	Baseline to Week 76
Secondary	Change From Baseline in Patient Reported Outcomes (NEI VFQ-25) at Week 24, Week 52 and Week 76	The National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) measures a patient's subjective assessment of vision-related Quality of Life (QoL).; The 11 subscales in the VFQ-25 are general vision, ocular pain, near activities, distance activities, social functioning, mental health, role difficulties, dependency, driving, color vision, and peripheral vision. The scores on the subscales were added together for a total score, which ranged from 0 to 100. A higher score indicated better vision-related quality of life.	Baseline, Week 24, Week 52 and Week 76
Secondary	Number of Subjects According to Their Anti-drug Antibody (ADA) Titer at Screening and Week 4, Week 12, Week 24, Week 36, Week 52 and Week 76	Anti-drug antibodies (ADA) levels were assessed from subjects assigned to brolucizumab treatment only.	Baseline, Week 4, Week 12, Week 24, Week 36, Week 52 and Week 76
