Brief summary

The purpose of this study is to assess the Safety and Efficacy of IONIS-FB-Lrx for up to 120 patients with Geographic Atrophy secondary to Age Related Macular Degeneration

Detailed description

This study will assess changes in complement factor B over a 69-week treatment period in a patient population 55 and older with well-demarcated Geographic Atrophy secondary to Age Related Macular Degeneration

Interventions

Single Dose of IONIS-FB-Lrx administered once weekly for weeks 1-3, and every other week or less frequently until week 70

DRUGPlacebo (sterline saline 0.9%)

Calculated volume to match active comparator. Administered subcutaneously weekly for weeks 1-3, and every other week or less frequently until week 70

Design outcomes

Primary

MeasureTime frameDescription
Efficacy of IONIS-FB-LrxUp to 74 weeksThe Efficacy of IONIS-FB-Lrx will be measured by the percent change in plasma complement factor B level

Secondary

MeasureTime frameDescription
Incidence and severity of adverse events that are related to treatment with IONIS-FB-LrxUp to 86 weeksThe safety and tolerability of IONIS-FB-Lrx will be assessed by determining the incidence and severity of adverse events that are related to treatment with IONIS-FB-Lrx
Proportion of patients in each treatment group achieving a >50% reduction of plasma complement factor BUp to 74 weeksProportion of patients in each treatment group achieving a \>50% reduction of plasma complement factor B from Baseline to Post-Treatment
Effect of IONIS-FB-Lrx on the rate of change of the area of GA secondary to AMDUp to 74 weeksEffect of IONIS-FB-Lrx on the rate of change of the area of GA secondary to AMD as measured by Fundus Autofluorescence from Baseline to Post-Treatment
Effect of factor B reduction on other components of the complement pathways in AMD patientsUp to 74 weeksEffect of factor B reduction on other components of the complement pathways such as AH50, CH50 and Bb in AMD patients from Baseline to Post-Treatment
