Intravitreal Brolucizumab in Neovascular Age-related Macular Degeneration With Limited Response to Aflibercept

• Male or female patients ≥ 50 years of age.
• Patients with active subfoveal or juxtafoveal Type 1, 2 or 3 CNV secondary to AMD.
• Pre-treatment with intravitreal aflibercept in a treat and extend regimen with 2-weeks steps and failing to be extended by two weeks to either 6-weeks intervals, 8 week intervals or 10 week intervals without showing CNV activity (at least 2 attempts to extend).
• The total area of CNV (including both classic and occult components) encompassed within the lesion must be ≥ 50% of the total lesion area.
• The total lesion area ≤ 12 disc areas for minimally classic or occult with no classic component and ≤ 9 disc areas (5400μm) in greatest linear dimension with predominantly classic lesions.
• Patients who have a BCVA of at least 20/160 (letter score 40 letters) in the study eye using ETDRS charts.
• Willing and able to give written informed consent according to legal requirements, and who have signed the consent form prior to initiation of any study procedure including withdrawal from exclusionary medications for the purpose of this study.
• Willing and able to comply with study procedures.

Exclusion Criteria:

• Subretinal hemorrhage in the study eye that involves the center of the fovea, if the size of the hemorrhage is either ≥ 50% of the total lesion area or ≥ 1 disc area in size.
• Presence of a retinal pigment epithelial tear involving the fovea in the study eye.
• Patients with angioid streaks or precursors of CNV in either eye due to other causes, such as ocular histoplasmosis, trauma, or pathologic myopia.
• Concurrent disease in the study eye that could compromise visual acuity or require medical or surgical intervention during the 12 months study period.
• Vitreous hemorrhage or history of retinal detachment or macular hole (Stage 3 or 4) in the study eye.
• Active intraocular inflammation (grade trace or above) in the study eye.
• Any active infection involving ocular adnexa including infectious conjunctivitis, keratitis, scleritis, endophthalmitis, as well as idiopathic or autoimmune-associated uveitis in either eye.
• History of uncontrolled glaucoma in the study eye (defined as intraocular pressure ≥ 25 mmHg despite treatment with anti-glaucoma medication).
• Aphakia with absence of the posterior capsule in the study eye.
• Any prior treatment in the study eye with radiation therapy, subfoveal focal laser photocoagulation, vitrectomy, transpupillary thermotherapy.
• History of submacular surgery or other surgical intervention for AMD in the study eye, glaucoma filtration surgery, corneal transplant surgery.
• Extracapsular extraction of cataract with phacoemulsification within three months preceding Baseline, or a history of post-operative complications within the last 12 months preceding Baseline in the study eye (uveitis, cyclitis, etc.).
• Use of other investigational drugs at the time of baseline, or within 30 days or 5 half- lives of baseline, whichever is longer (excluding vitamins and minerals).
• Previous violation of the posterior capsule in the study eye unless it occurred as a result of YAG posterior capsulotomy in association with prior, posterior chamber intraocular lens implantation.
• History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use an investigational drug or that might affect interpretation of the results of the study or render the subject at high risk for treatment complications.
• Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test (>5 mIU/ml).
• History of hypersensitivity or allergy to fluorescein.
• Inability to obtain OCTs, OCTAs, fundus photographs or fluorescein angiograms of sufficient quality.
