The present invention relates to RNAi agents, e.g.,
double stranded RNAi agents, targeting the
Kallikrein B,
Plasma (Fletcher Factor) 1 (KLKB1)
gene, the
Factor XII (Hage- man Factor (F12)
gene, or the Kiningen 1 (KNG1)
gene, and methods of using such RNAi agents to inhibit expression of a KLKB1 gene, an F12 gene, and / or a KNG1 gene, and methods of treating subjects having an hereditary an- gioedema (HAE) and / or a
contact activation pathway-associated disorder.
