  • Difference of \<10% in ECD at screening between the 2 eyes as measured by specular microscopy and determined by the independent reading center
  • Availability of historical visual acuity (VA) data and spectral-domain optical coherence tomography (SD-OCT). Additionally, fluorescein angiography or color fundus photography can both be used to support participant eligibility per protocol at investigator discretion
  • Availability of comprehensive historical anti-vascular endothelial growth factor (VEGF) injection data, including agent administered and date of administration from the time of diagnosis, or for at least 2 years prior to screening if diagnosis was made more than 2 years before screening
  • Response to at least two prior anti-VEGF IVT injections as determined by the investigator based on the following:
    • Overall decrease in nAMD disease activity detected on historical or screening OCT
    • Stable or improved best-corrected visual acuity (BCVA)
  • BCVA of 34 letters (approximate 20/200 Snellen equivalent) or better, using Early Treatment of Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters at screening and enrollment
