Neovascular Age Related Macular Degeneration, nAMD
About this trial
This is an interventional treatment trial for Neovascular Age Related Macular Degeneration
Eligibility Criteria
Inclusion Criteria:
- Initial diagnosis of nAMD within 9 months prior to the screening visit
- Previous treatment with at least three anti-VEGF intravitreal injections for nAMD per standard of care within 6 months prior to the screening visit
- Demonstrated response to prior anti-VEGF intravitreal treatment since diagnosis
- Availability of historical VA data prior to the first anti-VEGF treatment for nAMD up to the screening visit
- BCVA of 34 letters or better (20/200 or better approximate Snellen equivalent), using Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters
- All subtypes of nAMD lesions are permissible
- Sufficiently clear ocular media and adequate pupillary dilation to allow for analysis and grading by the central reading center of FP, FA, ICGA, FAF, and OCT images
Exclusion Criteria:
Study Eye
- History of vitrectomy surgery, submacular surgery, or other surgical intervention, all for AMD
- Prior treatment with Visudyne, external-beam radiation therapy, or transpupillary thermotherapy
- Previous treatment with corticosteroid intravitreal injection
- Previous intraocular device implantation (not including intraocular lens implants)
- Previous laser (any type) used for AMD treatment
- Treatment with anti-VEGF agents other than ranibizumab within 1 month prior to the randomization visit
- Concurrent conjunctival, Tenon's capsule, and/or scleral condition in the supero temporal quadrant of the eye that may affect the implantation, subsequent tissue coverage, and refill-exchange procedure of the PDS implant
- Subretinal hemorrhage that involves the center of the fovea, if the hemorrhage is greater than 0.5 disc area (1.27 mm2) in size at screening
- Subfoveal fibrosis or subfoveal atrophy
- Retinal pigment epithelial tear
- Any concurrent intraocular condition
- Active intraocular inflammation (grade trace or above)
- History of vitreous hemorrhage
- History of rhegmatogenous retinal detachment
- History of rhegmatogenous retinal tears or peripheral retinal breaks within 3 months prior to the randomization visit
- History of pars plana vitrectomy surgery
- Aphakia or absence of the posterior capsule
- Spherical equivalent of the refractive error demonstrating more than 8 diopters of myopia
- Preoperative refractive error that exceeds 8 diopters of myopia, for patients who have undergone prior refractive or cataract surgery
- Intraocular surgery (including cataract surgery) within 3 months preceding the randomization visit
- Uncontrolled ocular hypertension or glaucoma
- History of glaucoma-filtering surgery, tube shunts, or microinvasive glaucoma surgery
- History of corneal transplant
Fellow (Non-Study) Eye
• Non-functioning fellow eye
Either Eye
- Prior treatment with brolucizumab (at any time prior to the screening visit)
- Prior participation in a clinical trial involving anti-VEGF drugs within 6 months prior to the randomization visit
- Choroidal neovascularization due to other causes, such as ocular histoplasmosis, trauma, central serous chorio-retinopathy, or pathologic myopia
- Any history of uveitis
- Active infectious conjunctivitis, keratitis, scleritis, or endophthalmitis

Arm 2
Experimental
Experimental
Implant arm
Intravitreal arm
Participants will have the implant (pre-filled intraoperatively with ranibizumab 100 mg/mL) surgically inserted on Day 1. After Day 1, patients in the implant arm will attend monthly study visits, and receive implant refill-exchanges with ranibizumab 100 mg/mL at Week 24 and Week 48. At the Week 48 study visit, patients will move to the long term extension phase of the study and continue receiving refill-exchanges Q24W until the end of study. Patients will attend monthly visits up to Week 96 and bi-monthly visits, thereafter
Participants will receive intravitreal ranibizumab 0.5 mg injections starting on Day 1. Patients will receive intravitreal ranibizumab 0.5 mg Q4W until Week 44. At the Week 48 study visit, patients will receive the PDS implant (pre-filled intraoperatively with ranibizumab 100 mg/mL), move to the long-term extension phase of the study and receive Q24W refill exchanges until the end of study. If patients are unable to attend the Week 48 visit due to extenuating circumstances, they should return no later than the next scheduled visit (Week 52), when they will receive the PDS implant. Patients will attend monthly visits up to Week 96 and bi-monthly visits, thereafter.
