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, 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.
