Study of ARO-MMP7 Inhalation Solution in Healthy Subjects and Patients With Idiopathic Pulmonary Fibrosis

October 13, 2025 updated by: Arrowhead Pharmaceuticals

A Phase 1/2a Study Evaluating the Effects of ARO-MMP7 Inhalation Solution in Healthy Subjects and Patients With Idiopathic Pulmonary Fibrosis

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of ARO-MMP7 in normal healthy volunteers (NHVs) and in participants with idiopathic pulmonary fibrosis (IPF). The study will initiate with NHVs receiving single ascending doses of ARO-MMP7. Following evaluation of safety and pharmacodynamic (PD) data, participants will receive multiple doses of ARO-MMP7.
