  • Willing and able to sign the study written informed consent form (ICF)
  • Men and women aged 50 to 85 years diagnosed with nAMD at screening
  • Under active anti-VEGF treatment for nAMD with at least 3 injections within 6 months prior to screening
  • Response to anti-VEGF therapy defined as reduction in central retinal thickness by 50 micrometers or at least 30% reduction in fluid by OCT compared to worst disease
  • Best corrected visual acuity (BCVA) between 20/63 and 20/400 (63 to 19 ETDRS letters) for first patient in each cohort; BCVA between 20/40 and 20/400 (73 to 19 ETDRS letters) for other cohort members
  • Must be pseudophakic (at least 3 months after intraocular lens implantation) in the study eye
  • Female subjects must have been postmenopausal for at least 1 year
Not Eligible

You will not qualify if you...

  • Active or history of retinal detachment in the study eye
  • Uncontrolled glaucoma or ocular hypertension
  • Use of drugs known to have retinal toxicity
  • History of intraocular surgery
