Arrowhead Pharmaceuticals Files IND for Phase 2b Study of ARO-ANG3 for Treatment of Mixed Dyslipidemia

PASADENA, Calif.--(BUSINESS WIRE)--Arrowhead Pharmaceuticals Inc. (NASDAQ: ARWR) today announced that it has submitted an Investigational New Drug Application (IND) to the U.S. Food and Drug Administration (FDA) for a Phase 2b dose-finding clinical study of ARO-ANG3, the company’s investigational RNA interference (RNAi) therapeutic being developed as a treatment for patients with mixed dyslipidemia.

Javier San Martin, M.D., chief medical officer at Arrowhead, said: “Cardiovascular disease remains the major cause of death, even after advances in therapies that reduce LDL cholesterol. This highlights the need for new therapies that can help patients at risk for cardiovascular disease to optimize their lipid profiles and protect them from atherosclerosis progression and cardiovascular events. By inhibiting ANGPTL3, Arrowhead’s investigational ARO-ANG3 is designed to reduce triglycerides and decrease LDL cholesterol in patients with mixed dyslipidemia. We have been very encouraged by the clinical data from this program to date and look forward to further assessing the safety and efficacy of ARO-ANG3 in the upcoming Phase 2b study.”

Following FDA’s review of the IND, the company intends to initiate AROANG3-2001, a Phase 2b dose-finding clinical study in patients with elevated triglycerides and low-density lipoprotein cholesterol (LDL-C). The primary objective of the study is to evaluate the safety and efficacy of ARO-ANG3 in adults with mixed dyslipidemia and to select a dosing regimen for later stage clinical studies in this patient population. The study is designed to include a total of 180 participants in three cohorts. All dose cohorts will enroll in parallel, with 60 participants per cohort randomly assigned in a 3:1 ratio to receive ARO-ANG3 or placebo.

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.
