Arrowhead Pharmaceuticals Initiates Dosing Phase 1/2 Study of ARO-ENaC for Treatment of Cystic Fibrosis
ARO-ENaC is designed to reduce activity of the epithelial sodium channel alpha subunit in the airways of the lung. In patients with CF, dysfunction in the cystic fibrosis transmembrane conductance regulator (CFTR) causes increased ENaC activity which contributes to airway dehydration and reduced mucociliary transport. This predisposes patients to persistent lung infections, structural damage, and progressive loss of pulmonary function. ENaC has been extensively explored as a potential therapeutic target for CF, but the development of inhaled small molecule ENaC inhibitors has been limited by on-target renal toxicity and short duration of action in the lung.
AROENaC1001 is a Phase 1/2 dose-escalating study to evaluate the safety, tolerability, and pharmacokinetic effects of ARO-ENaC in up to 24 normal healthy volunteers and to evaluate the safety, tolerability, and efficacy in up to 30 patients with CF. Exploratory objectives in patients with CF include assessing the effects of ARO-ENaC on changes in lung clearance index (LCI) and evaluating changes in forced expiratory volume (FEV1).
