GOLDEN STUDY: A Study to Assess Safety and Efficacy of Multiple Doses of IONIS-FB-LRx in Participants With Geographic Atrophy Secondary to Age-Related Macular Degeneration (AMD)

The study will assess the rate of change of the area of GA secondary to AMD by measuring FAF in up to 330 participants with GA due to AMD being treated with IONIS-FB-LRx. The study is a Phase 2, double-masked, randomized, stratified, placebo-controlled study conducted at multiple centers. It is an adaptive design in which three dose levels will be evaluated in a subset of participants (Stage 1) and, following an interim analysis, the number of participants in two of the dose cohorts will be expanded (Stage 2).

• Best-corrected visual acuity (BCVA) letter score of 35 letters (approx. 20/200 Snellen equivalent) or better on the ETDRS chart
• Must have clear ocular media and adequate pupillary dilation in the study eye to permit high-quality fundus imaging

Exclusion criteria

• Clinically-significant abnormalities in medical history

• Prior treatment with another investigational drug, biological agent, or device
• Other protocol-specified inclusion/exclusion criteria may apply
