This research study will examine the safety and effectiveness of ONS-5010 in participants with AMD. The goal is to prevent vision loss by evaluating the effectiveness of ONS-5010 as compared with ranibizumab.

Inclusion Criteria:

• Active primary Subfoveal Choroidal Neovascularization lesions secondary to Age-related macular degeneration (AMD) in the study eye

• Best corrected visual acuity of 25-67 letters read (20/50 to 20/320 Snellen equivalent)

• Study eye must:

  • Have active leakage on Fluorescein Angiogram involving the fovea
  • Have edema involving the fovea
  • Be free of scarring, fibrosis, or atrophy involving the central foveal zone

Exclusion Criteria:

• Previous subfoveal focal laser photocoagulation in the study eye
• Laser photocoagulation (juxtafoveal or extrafoveal) in the study eye within 1-month preceding randomization
• Any concurrent intraocular condition in the study eye that may require medical or surgical intervention or contribute to vision loss within 1 year
• Active intraocular inflammation (grade trace or above) in the study eye
• Current vitreous haemorrhage in the study eye
• Polypoidal choroidal vasculopathy (PCV) in the study eye
• History of idiopathic or autoimmune-associated uveitis in either eye
• Infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye
• Uncontrolled glaucoma in the study eye (defined as intraocular pressure ≥30 mmHg despite treatment with anti-glaucoma medication)
• Premenopausal women not using adequate contraception
• Current treatment for active systemic infection
• Known allergy to any component of the study drug or history of allergy to fluorescein , not amenable to treatment

Data will not be shared until all global regulatory filings are complete.
