Arrowhead Pharmaceuticals is advancing two RNAi-based therapies, ARO-INHBE and ARO-ALK7, into clinical trials for obesity treatment, targeting novel mechanisms of action.
ARO-INHBE, designed to reduce hepatic expression of the INHBE gene, has shown potential in preclinical studies to reduce body weight and fat mass while preserving lean muscle mass.
A Phase 1/2a clinical trial for ARO-INHBE is planned, including a combination arm with tirzepatide, with regulatory clearance sought in New Zealand.
ARO-ALK7, the second obesity candidate, is also slated for clinical trial initiation by the end of 2024, expanding Arrowhead's pipeline in metabolic diseases.
