Analysis shows relationship between geographic atrophy growth, worsening vision loss
Key takeaways:
- A post hoc analysis found a relationship between geographic atrophy growth and worsening vision loss.
- Fewer patients who received avacincaptad pegol had a loss of 10, 15 or 20 letters from baseline.
A relationship was found between geographic atrophy growth and worsening vision loss in a post hoc analysis of the phase 3 GATHER1 and GATHER2 pivotal clinical trials investigating avacincaptad pegol, according to Iveric Bio.
“This is the first time a relationship between disease progression and worsening visual acuity has been observed in GA, connecting anatomy and function,” Carl Danzig, MD, said in a press release. “These data suggest that in the ACP-treated group, the reduction in growth of GA resulted in an overall lower rate of vision loss.”

Danzig presented the findings at the Association for Research in Vision and Ophthalmology meeting in New Orleans.
At 12 months, fewer patients who received avacincaptad pegol (ACP) had a loss of 10, 15 or 20 letters from baseline at two consecutive visits compared with sham, according to the release.
A previously released post hoc analysis found that there was a 56% risk reduction in the rate of persistent vision loss in patients with geographic atrophy (GA) who received ACP 2 mg compared with sham over 12 months of treatment.
