Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 55 or older with GA due to AMD who can undergo intravitreal injections, comply with follow-up visits, and meet the study's contraception and safety requirements.
✕Probably not a fit
Patients with non-AMD causes of retinal degeneration, very advanced GA with extensive central atrophy, or those unwilling/unable to receive intravitreal injections are unlikely to benefit from this trial.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Participants are randomized to receive intravitreal ONL1204 (two dose levels and treatment frequencies), avacincaptad pegol, or sham injections and are followed over scheduled clinic visits. The trial collects safety data and measures of anatomic lesion growth and visual function using retinal imaging and vision tests. Inclusion criteria focus on adults 55 and older with GA secondary to AMD who can attend study visits and meet contraception requirements. The goal is to determine whether ONL1204 can protect retinal cells and slow GA progression compared with sham or an active comparator.
Why it matters
Potential benefit: If successful, ONL1204 could slow geographic atrophy progression and help preserve vision in people with GA from AMD.
How similar studies have gone: Related complement-targeting therapies have shown some ability to slow GA in prior trials, while ONL1204 is a novel, first-in-class mechanism with limited human data so far.
