About Arrowhead Pharmaceuticals

Arrowhead Pharmaceuticals develops medicines that treat intractable
diseases by silencing the genes that cause them. Using a broad portfolio
of RNA chemistries and efficient modes of delivery, Arrowhead therapies
trigger the RNA interference mechanism to induce rapid, deep, and
durable knockdown of target genes. RNA interference, or RNAi, is a
mechanism present in living cells that inhibits the expression of a
specific gene, thereby affecting the production of a specific protein.
Arrowhead’s RNAi-based therapeutics leverage this natural pathway of
gene silencing. The company’s pipeline includes ARC-520 and ARC-521 for
chronic hepatitis B virus infection, ARC-AAT for liver disease
associated with alpha-1 antitrypsin deficiency, ARC-F12 for hereditary
angioedema and thromboembolic disorders, ARC-LPA for cardiovascular
disease, and ARC-HIF2 for renal cell carcinoma.
