Arrowhead Pharmaceuticals Inc. announced that it has filed an application for clearance to initiate a Phase 1/2a clinical trial of ARO-RAGE, the company's investigational RNA interference therapeutic designed to reduce production of the receptor for advanced glycation end products (RAGE) as a potential treatment for asthma and other inflammatory pulmonary diseases. An application for approval of the clinical trial was submitted to a local Ethics Committee and to the New Zealand Medicines and Medical Devices Safety Authority for review by the Standing Committee on Therapeutic Trials. Pending clearance, Arrowhead intends to proceed with ARORAGE-1001, a Phase 1/2a study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ARO-RAGE in up to 64 healthy volunteers and in up to 16 patients with asthma.
