Overview
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.

Inclusion Criteria (IPF Participants):
- Age ≥ 45 years at Screening
- Clinical diagnosis consistent with IPF based upon established criteria confirmed by review of high-resolution computed tomography (HRCT) and surgical lung biopsy findings (if available)

- Stable IPF disease at Screening with minimum life expectancy of ≥ 12 months from Screening
- Female participants cannot be pregnant or lactating
- Male and female participants of childbearing potential must agree to use highly effective contraception and must not donate eggs/sperm during the study and for at least 90 days following end of study or last dose of study drug, whichever is later.
