Primary Outcome Measures :
  1. The rate of change in GA lesion area as measured by fundus autofluorescence (FAF) over the 52 weeks of treatment [ Time Frame: 52 Weeks ]
    The primary efficacy endpoint

  2. The incidence and severity of ocular and systemic adverse events from treatment with NGM621 administered every 4 or 8 weeks compared to Sham [ Time Frame: 52 Weeks ]
    The primary safety endpoints

Ages Eligible for Study:   55 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female (non-pregnant, non-lactating) subjects ≥ 55 years
  • Standard luminance BCVA score of 34 letters or better using ETDRS charts at the starting distance of 4 meters (approximately 20/200 Snellen equivalent or better) in study eye
  • Clinical diagnosis of GA secondary to AMD:

    1. Total GA area must be ≥ 2.5 and ≤ 17.5 mm²
    2. If GA is multifocal, at least one focal lesion must be ≥ 1.25 mm² (0.5 DA), with the overall area of GA ≥ 2.5 and ≤ 17.5 mm²
    3. Well demarcated GA with no anatomical evidence of current or prior CNV in the study eye

Exclusion Criteria:

Study Eye

  • GA secondary to a condition other than AMD in either eye (e.g., monogenetic macular dystrophies like Stargardt disease, cone rod dystrophy, or toxic maculopathies)
  • Any history of or active choroidal neovascularization (CNV)

Both Eyes

  • Any history of or active bacterial, viral, fungal, or parasitic infection in either eye in the 3 months prior to randomization
