Researchers are looking for new ways to treat neovascular age-related macular degeneration (NVAMD).
Available standard (usual) treatments for NVAMD, such as aflibercept, may not work for every person. Researchers want to learn if a trial medicine called tiespectus (also called MK-8748 or EYE201) can treat NVAMD.
The goal of this trial is to learn if tiespectus works as well as aflibercept to treat NVAMD.
Has treatment naive choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) including subfoveal, juxtafoveal and extrafoveal lesions or retinal angiomatous proliferations (RAP) and polypoidal choroidal vascularization (PCV) lesions in at least one eye (study eye)
The diagnosis of neovascular age-related macular degeneration (NVAMD) must have been made within 21 days prior to starting study treatment
Has uncontrolled blood pressure at screening
History of any prior macular laser photocoagulation in the study eye
History of uveitis in either eye
History of cataract surgery, minimally invasive glaucoma surgery, or Yttrium-Aluminium Garnet (Yag) laser capsulotomy in the study eye within 90 days before entering the study
Parallel

Mean Change in Best-Corrected Visual Acuity (BCVA) [Early Treatment of Diabetic Retinopathy Study (ETDRS Letters)] From Baseline to Year 1
Participants' BCVA in the study eye will be measured using the Early Treatment of Diabetic Retinopathy (ETDRS) methodology. The ETDRS letter score ranges from 0 to 100, with a higher score indicating better visual acuity. Mean change in ETDRS letters from baseline to Year 1 will be assessed.
Mean Change in BCVA (ETDRS Letters) From Baseline (Day 1) Over Time to Year 1
Participants' BCVA in the study eye will be measured using the Early Treatment of Diabetic Retinopathy (ETDRS) methodology. The ETDRS letter score ranges from 0 to 100, with a higher score indicating better visual acuity. The mean change in BCVA from baseline over time to year 1 will be assessed.
Proportion of Participants Who Gain ≥5 ETDRS Letters at Year 1
Participants' BCVA in the study eye will be measured using the Early Treatment of Diabetic Retinopathy (ETDRS) methodology. The ETDRS letter score ranges from 0 to 100, with a higher score indicating better visual acuity.
Proportion of Participants Who Gain ≥10 ETDRS Letters at Year 1
Participants' BCVA in the study eye will be measured using the Early Treatment of Diabetic Retinopathy (ETDRS) methodology. The ETDRS letter score ranges from 0 to 100, with a higher score indicating better visual acuity.
Proportion of Participants Who Gain ≥15 ETDRS Letters at Year 1
Participants' BCVA in the study eye will be measured using the Early Treatment of Diabetic Retinopathy (ETDRS) methodology. The ETDRS letter score ranges from 0 to 100, with a higher score indicating better visual acuity.
