A 60-week, Phase IIIb, Randomized, Multi-center Study Assessing the Efficacy and Safety of a Personalized Monotherapy Regimen of Brolucizumab in Patients With Symptomatic Macular Polypoidal Choroidal Vasculopathy (PROUD Study)

CRTH258AKR03

This study is a 60-week, two-arm, randomized, open-label, active-controlled, multi-center study in patients with Polypoidal choroidal vasculopathy (PCV) who have not previously received anti-Vascular endothelial growth factor (VEGF) treatment.

Inclusion Criteria: 1. Signed informed consent must be obtained prior to participation in the study. 2. Participants ≥ 50 years of age at Screening. Study eye: 3. Presence of active polypoidal lesions in the macula as shown by Indocyanine green angiography (ICGA) AND presence of serosanguinous maculopathy, i.e., exudative or hemorrhagic features involving the macula on color fundus photography (CFP), Fluorescein angiography (FA) and spectral domain optical coherence tomography (SD-OCT) AND presence of Intraretinal fluid (IRF) or Subretinal fluid (SRF) that affects the central subfield as seen by SD-OCT. 4. Best-corrected visual acuity (BCVA) score must be ≤ 78 and ≥ 24 letters at 4 meters starting distance using early treatment diabetic retinopathy study (ETDRS) visual acuity charts at both Screening and Baseline. 5. Greatest liner dimension (GLD) of the total lesion area (branching vascular network \[BVN\] + polypoidal lesion) \< 5400 μm (equivalent to 9 macular photocoagulation study \[MPS\] Disc Area) as delineated by Indocyanin green angiography (ICGA). Exclusion Criteria: Ocular conditions: 1. Concomitant conditions or ocular disorders in the study eye at Screening or Baseline which could, in the opinion of the Investigator, prevent response to study treatment or may confound interpretation of study results, compromise visual acuity or require planned medical or surgical intervention during the first 12-month study period. 2. Any active intraocular or periocular infection or active intraocular inflammation (IOI) (e.g., infectious conjunctivitis, keratitis, scleritis, endophthalmitis, infectious blepharitis, uveitis) in study eye or fellow eye at Screening or Baseline. 3. Uncontrolled glaucoma in the study eye defined as intraocular pressure (IOP) \> 25 mmHg on medication, or according to Investigator's judgment, at Screening or Baseline. 4. Any Polypoidal choroidal vasculopathy (PCV) masquerades like macular aneurysms, macular telangiectasia, etc. in study eye. 5. Total area of subretinal hemorrhage larger than 9 DA (Disc Area) or comprising ≥ 50% of the lesion area or presence of vitreous hemorrhage in study eye. Ocular treatments in the study eye: 6. Previous treatment with any anti-Vascular endothelial growth factor (VEGF) drugs or investigational drugs at any time prior to Baseline. 7. Previous use of intraocular or periocular steroids within the 6-month period prior to Baseline. 8. Macular laser photocoagulation (focal/grid) or Photodynamic therapy (PDT) at any time prior to Baseline and peripheral laser photocoagulation within 3 months prior to Baseline. Systemic conditions or treatments: 9. Stroke or myocardial infarction during the 6-month period prior to Baseline. 10. Systemic anti-VEGF therapy any time prior to Baseline.
