IONIS-FB-LRx is a specific antisense oligonucleotide (ASO) targeting complement factor B (CFB). IONIS-FB-LRx effectively reduces circulating levels of CFB. IONIS-FB-LRx can be used for geographic atrophy (GA) research[1][2].
in vivo
IONIS-FB-Lrx is administered by subcutaneous injection every four weeks and targets CFB’s hepatic expression[2].
