PASADENA, Calif.--(BUSINESS WIRE)--Arrowhead Pharmaceuticals Inc. (NASDAQ: ARWR) today announced that it has submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for an adaptive Phase 2/3 trial with the potential to serve as a pivotal registrational study of ARO-AAT, the company’s second generation subcutaneously administered RNA interference (RNAi) therapeutic being developed as a treatment for a rare genetic liver disease associated with alpha-1 antitrypsin deficiency (AATD).
Bruce Given, M.D., chief operating officer and head of R&D at Arrowhead, said: “Our discussions with the FDA have been productive and helpful as we moved through the process of determining the Phase 2/3 adaptive trial design with appropriate surrogate endpoints. We look forward to initiating this trial and moving closer to potentially providing patients, physicians, and the alpha-1 community with a much-needed therapy for alpha-1 liver disease.”
Pending regulatory review, the company intends to initiate the adaptive design, Phase 2/3 study of ARO-AAT in patients with AATD associated liver disease. The proposed primary objectives are to evaluate safety and pharmacodynamic dose response, and to evaluate efficacy, defined as an improvement in a histologic grading scale of AATD associated liver disease, and no worsening of liver fibrosis based on Ishak score on end of study biopsy.
Arrowhead intends to initiate the study at various sites in the U.S. in the second quarter of 2019, followed by various international sites in Europe, pending regulatory submission and review. The company plans to provide additional study details following its initiation.
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.
