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

July 13, 2026 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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: Day 1 up to Day 85
An adverse event (AE) was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to study drug. TEAEs were defined as AEs with onset after administration of the study drug, or when a pre-existing medical condition increases in severity or frequency after study drug administration. A summary of all Serious Adverse Events (SAEs) and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
