IONIS-FB-L

Generation 2+ LICA antisense drug

IONIS-FB-LRx is a Generation 2+ ligand-conjugated antisense (LICA) drug designed to reduce the production of complement factor B (FB). Genetic association studies have shown that overaction of this cascade has been associated with the development of several complement-mediated diseases, including dry age-related macular degeneration (AMD). FB, a key regulatory protein, is produced predominately in the liver and circulates at high levels throughout the vascular system, including in capillaries in the eye. 1-5

About AMD

AMD is the leading cause of central vision loss in developed countries. It is estimated that more than three million people in the United States will be affected by the disease by 2020.6. AMD is believed to be a systemic disease with local disease manifestation at the aging retinal macula. AMD gradually destroys vision in the center of the visual field due to progressive damage of the retina.7
