Screening Stage

Formal Criteria Application

Clinician’s Expert Judgment (Manual Screening)

1. Automated Screening

• Aged 50 years or older

• Confirmed diagnosis of nAMD in at least one eye

• Previously treated with at least three monthly intravitreal anti-VEGF injections (with drugs different from faricimab)

• Injection interval approximately aligning with the trial’s window

• Meeting broad visual acuity criteria

• Absence of recent contraindicating surgery

(Not applicable)

2. Manual Screening

• Demonstrates an ongoing need for treatment (i.e., incomplete or unstable disease control)

• Assessed sufficient media clarity and fixation: By scrutinizing recent OCT, fundus photos, and clinical notes for artifacts or pathologies that would preclude quality imaging.

• Assessed Likely BCVA ≥ 24 letters: By reviewing recent visual acuity records from clinical notes.

• Assessed ability and willingness for follow-up: By contacting the patient directly via telephone to confirm their commitment, logistical feasibility, and understanding of the study requirements.

3. In-Person Screening

• Sufficient media clarity and fixation to permit high-quality imaging

• BCVA of at least 24 ETDRS letters

• Able and willing to attend regular follow-up visits for the 56-week study period

(Formal confirmation and final data collection at the visit)
