Home > Press > Arrowhead Presents ARC-520 and ARC-521 Clinical Data at The International Liver Congress(TM)

Abstract:
Arrowhead Pharmaceuticals Inc. (NASDAQ: ARWR) today presented clinical data from a Phase 2 study of ARC-520 and a Phase 1/2 study of ARC-521, the company's prior generation investigational medicines that were being studied for the treatment of chronic hepatitis B virus (HBV) infection, at The International Liver Congress™ 2017 (ILC), the annual meeting of the European Association for the Study of the Liver (EASL).

Arrowhead Presents ARC-520 and ARC-521 Clinical Data at The International Liver Congress(TM)

Pasadena. CA | Posted on April 20th, 2017

Together, these presentations demonstrate that in human clinical studies, RNAi interference (RNAi) as a mechanism can rapidly and significantly reduce HBV viral antigens. In addition, RNAi appears to synergize with current standard-of-care nucleotide and nucleoside analogues (NUCs) to rapidly lower serum levels of HBV DNA. Arrowhead is currently developing ARO-HBV, a follow-on product candidate that utilizes the company's next generation, proprietary subcutaneously administered delivery vehicle, as a potentially curative therapy for patients with chronic hepatitis B infection.

Bruce Given, M.D., chief operating officer, head of R&D for Arrowhead Pharmaceuticals, said: "Arrowhead's ARC-520 and ARC-521 clinical studies have generated important data that continue to inform and guide the development path of ARO-HBV, our follow-on candidate against chronic HBV. We saw reductions in hepatitis B surface antigen, or HBsAg, of up to 3 logs following multiple doses with ARC-520 in combination with a NUC. HBV DNA was reduced by several logs and became undetectable in many patients. In addition, early data from the ARC-521 study indicate that RNAi therapeutics can be active against HBV gene products derived from both cccDNA and integrated HBV DNA. These data are consistent with findings from a long-term study in chimpanzees that we reported on previously. We view these results as validation for the use of RNAi in HBV, and believe ARO-HBV has the potential to serve as a cornerstone therapy for combinations intended to cure chronic HBV."

About Arrowhead Pharmaceuticals, Inc.
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.
