Arrowhead Pharmaceuticals Files for Regulatory Clearance to Begin Phase 1 Study of ARO-ANG3

— Arrowhead to host R&D Day October 16, 2018 to discuss ARO-ANG3 and its emerging pipeline of RNAi therapeutics

PASADENA, Calif.--()--Arrowhead Pharmaceuticals Inc. (NASDAQ: ARWR) today announced that it has filed an application for approval to begin a Phase 1 clinical trial of ARO-ANG3, an RNAi-based investigational medicine targeting angiopoietin like protein 3 (ANGPTL3) being developed for the treatment of dyslipidemias and metabolic diseases. ARO-ANG3 will be the fourth therapeutic candidate to enter clinical studies that leverages Arrowhead’s Targeted RNAi Molecule (TRiM™) platform.

Chris Anzalone, Ph.D., president and CEO of Arrowhead Pharmaceuticals, said: “The ARO-ANG3 program has moved rapidly through preclinical development and we are thrilled to now submit the regulatory filing ahead of schedule. After positive initial signs of tolerability and activity with ARO-AAT and ARO-HBV, our first two clinical programs leveraging the TRiM™ platform, we are moving into the ARO-ANG3 clinical program with confidence.”

Pending approval, Arrowhead intends to proceed with AROANG1001, a Phase 1 single and multiple dose study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effect of ARO-ANG3 in adult healthy volunteers and dyslipidemic patients. The study is designed to enroll up to 70 subjects.

An application was submitted to an ethics committee in compliance with the Clinical Trial Notification process of the Australian Department of Health and Ageing, Therapeutic Goods Administration.

As a reminder, Arrowhead will host a Research & Development (R&D) Day to discuss ARO-ANG3 and its emerging pipeline of RNAi therapeutics that leverage the Company’s proprietary Targeted RNAi Molecule (TRIM™) platform on October 16, 2018 in New York City.

The R&D Day will feature presentations by Ira Goldberg, M.D. (NYU Langone Medical Center), who will discuss the current treatment landscape and unmet medical need for patients with dyslipidemia and hypertriglyceridemia.

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.
