study of innovative multimodal imaging biomarkers to predict anatomical outcome in naive patients with wamd treated with brolucizumab.

Conditions: Neovascular Age-related Macular Degeneration

Summary: the purpose of this study was to identify innovative early imaging parameters as predictors of the long-term clinical response to brolucizumab in terms of fluid resolution in patients with wet age-related macular degeneration (wamd) to evaluate their potential in supporting the choice of treatment regimen (q12w or q8w).

the study was a one-year, open-label, single arm, multicenter, phase iv study in patients with wamd. the study planned to enroll approximately 263 (male and female) patients aged 50 years or older with untreated active subfoveal choroidal neovascularization (cnv) secondary to wamd in the study eye from approximately 30 centers in italy. the duration of the study treatment for enrolled patients was a maximum of 48 weeks, consisting of 8 weeks of three monthly loading doses and 40 weeks of maintenance regimen period (q8w or q12w) according to disease activity assessment.

Eligibility criteria:
inclusion criteria: * signed written informed consent must be obtained prior to participation in the study * active choroidal neo-vascularization (cnv) secondary to amd that affects the central subfield, including retinal angiomatous proliferation (rap) with a cnv component, confirmed by presence of active leakage from cnv seen by fluorescein angiography (or other imaging modalities) and sequelae of cnv, e.g. pigment epithelial detachment (ped), subretinal or sub-retinal pigment epithelium (sub-rpe) hemorrhage, blocked fluorescence, macular edema in the study eye at screening; * presence of intraretinal fluid (irf) or subretinal fluid (srf) affecting the central subfield (study eye), as seen by sd-oct in the study eye at screening; * best-corrected visual acuity (bcva) score greater than or equal to 23 letters measured at 4-meters starting distance using early treatment diabetic retinopathy study (edtrs) visual acuity charts at both screening and baseline visits in the study eye. exclusion criteria: * any active intraocular or periocular infection or active intraocular inflammation (e.g. infectious conjunctivitis, keratitis, scleritis, endophthalmitis, infectious blepharitis) in study eye at screening or baseline; * not interpretable octa and sd-oct images according to investigator's clinical judgment at screening in the study eye; * concomitant conditions or ocular disorders in the study eye, at screening or baseline which, in the opinion of the investigator, could prevent response to study treatment or may confound interpretation of study results, compromise visual acuity or require planned medical or surgical intervention during the course of the study; * 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; * previous treatment with any anti-vascular endothelial growth factor (anti-vascular endothelial growth factor (vegf)) drugs or investigational drugs (other than vitamin supplements) in the study eye at any time prior to screening; * systemic anti-vegf therapy at any time; * stroke or myocardial infarction in the 6-month period prior to baseline.
