A Clinical Trial of EYE201/MK-8748 in People With Macular Degeneration (MK-8748-002)

Phase 3RecruitingNCT07440225

EyeBiotech Ltd.960 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.

Time frame: Baseline and Year 1

Secondary Outcomes

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.

Time frame: Up to Year 1

Proportion of Participants Who Gain ≥5 ETDRS Letters at Year 1

Time frame: Year 1

Proportion of Participants Who Gain ≥10 ETDRS Letters at Year 1

Time frame: Year 1

Proportion of Participants Who Gain ≥15 ETDRS Letters at Year 1

Time frame: Year 1

Proportion of Participants Who Lose ≥5 ETDRS Letters at Year 1

Time frame: Year 1

Proportion of Participants Who Lose ≥10 ETDRS Letters at Year 1

Time frame: Year 1

Proportion of Participants Who Lose ≥15 ETDRS Letters at Year 1

Time frame: Year 1

Mean Change in Spectral Domain Optical Coherence Tomography (SD-OCT) Central Subfield Thickness (CST) From Baseline (Day 1) To Year 1

CST will be measured in microns using SD-OCT. Mean change in CST from baseline to Year 1 will be assessed.

Time frame: Baseline and Year 1

Number of Participants who Experience One or More Systemic Adverse Events (AEs)

An AE is any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related. Therefore, an AE can be any unfavorable and unintended sign (including an abnormal clinical laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

Time frame: Up to approximately 96 weeks

Number of Participants who Experience One or More Ocular AEs

An ocular adverse event (OAE) is defined as any untoward medical occurrence involving the eye or ocular adnexa (including eyelids, conjunctiva, lacrimal apparatus, extraocular muscles, and orbit) that: Occurs or worsens after the first administration of the investigational product (IP) or a study-related ocular procedure, and does not necessarily have a causal relationship with the IP or procedure. OAEs include, but are not limited to, changes in: Symptoms (e.g., ocular pain, photophobia, floaters, blurred vision), Visual function (e.g., best-corrected visual acuity \[BCVA\], visual field). Intraocular pressure (IOP), Anterior segment findings (e.g., conjunctival hyperemia, keratitis, anterior chamber inflammation), Posterior segment findings (e.g., vitreous inflammation, retinal hemorrhages, retinal tears or detachment, macular edema), or ocular adnexa (e.g., eyelid edema, ptosis)

Time frame: Up to approximately 96 weeks
