PASADENA, Calif.--(BUSINESS WIRE)--Nov. 13, 2020-- Arrowhead Pharmaceuticals, Inc. (NASDAQ: ARWR) today announced positive clinical data from multiple product candidates in its cardiometabolic pipeline at the American Heart Association (AHA) Scientific Sessions 2020.

Javier San Martin, M.D., chief medical officer at Arrowhead, said: “The data presented at AHA on our cardiometabolic pipeline continue to show strong and consistent response across a range of lipid parameters. There remains significant residual cardiovascular risk despite recent scientific advances, and we believe that our cardiometabolic pipeline has the ability to target new therapeutic targets and address multiple lipid parameters associated with increased cardiovascular risk.”

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.
