Listen to the news
  • ARO-ALK7 is the first investigational RNAi therapeutic to enter clinical studies that targets a gene expressed in adipose tissue
  • Study initiation highlights Arrowhead's leadership in the delivery of siRNA to multiple tissues and cell types throughout the body utilizing its proprietary and differentiated Targeted RNAi Molecule (TRiM™) platform
  • In preclinical studies, ARO-ALK7 silenced Activin receptor-like kinase 7 (ALK7) expression in adipose tissue, which led to reduced body weight and fat mass with preservation of lean muscle

Arrowhead Pharmaceuticals, Inc. (NASDAQ:ARWR) today announced that it has dosed the first subjects in a Phase 1/2a clinical trial of ARO-ALK7, the company's investigational RNA interference (RNAi) therapeutic being developed as a potential treatment for obesity. ARO-ALK7 is designed to intervene in a known pathway that signals the body to store fat in adipose tissue. The study initiates in otherwise healthy obese subjects using single and multiple escalating doses of ARO-ALK7 monotherapy and is expected to progress rapidly to investigate combinations of ARO-ALK7 with tirzepatide in obese patients with and without type 2 diabetes.
