Summary
To compare brolucizumab to aflibercept in Chinese patients with untreated active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD)
Eligibility Criteria
Inclusion Criteria
- Written informed consent must be obtained before any assessment was performed.
- Male or female Chinese participants ≥ 50 years of age at the time of screening.
- Active CNV lesions secondary to AMD that affect the central subfield (including retinal angiomatous proliferation lesions with a CNV component) in the study eye at screening and confirmed by the Central Reading Center (CRC).
- Total area of CNV (including both classic and occult components) must comprise > 50% of the total lesion area in the study eye at screening and confirmed by the CRC.
- Intra and/or subretinal fluid affecting the central subfield of the study eye at screening and confirmed by the CRC.
- BCVA between 78 and 23 letters, inclusive, in the study eye at screening and baseline using ETDRS testing.
Exclusion Criteria
- Any active intraocular or periocular infection or active intraocular inflammation (e.g., infectious conjunctivitis, keratitis, scleritis, endophthalmitis, infectious blepharitis, uveitis) in study eye at baseline.
- Central subfield of the study eye affected by fibrosis or geographic atrophy assessed by color fundus photography at screening and confirmed by the CRC.
- Total area of fibrosis ≥ 50% of the total lesion in the study eye at screening and confirmed by the CRC.
- Subretinal blood affecting the foveal center point and/or ≥ 50% of the lesion of the study eye at screening and confirmed by the CRC.
- Previous treatment with any approved or investigational drugs for nAMD in the study eye (other than vitamin supplements).
- Retinal pigment epithelium rip/tear in the study eye at screening.
- Current vitreous hemorrhage or history of vitreous hemorrhage in the study eye within 4 weeks prior to baseline.
