Conditions

Idiopathic Pulmonary Fibrosis

Brief summary

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.

Interventions

DRUGARO-MMP7 Inhalation Solution

ARO-MMP7 by inhalation of nebulized solution

DRUGPlacebo

Calculated volume of normal saline (0.9% NaCl) to match active treatment by inhalation of nebulized solution

Inclusion criteria

(NHVs): * Normal pulmonary function tests at Screening * Normal electrocardiogram (ECG) at Screening * Non-smoking * 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. 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) * Safely able to undergo bronchoscopy * 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.

Exclusion criteria

(NHVs): * Acute lower respiratory infection within 30 days prior to first dose or acute upper respiratory infection within 7 days prior to first dose * Positive coronavirus disease (COVID-19) test during Screening window * Any history of chronic pulmonary disease or anaphylaxis * Human immunodeficiency virus (HIV) infection, seropositive for hepatitis B virus (HBV), seropositive for hepatitis C virus (HCV) * Uncontrolled hypertension * History of significant cardiac disease * History of major surgery within 12 weeks prior to first dose * Unwilling to limit alcohol consumption to within moderate limits for the duration of the study * Use of illicit drugs * Use of an investigational agent or device within 30 days prior to first dose

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)Day 1 up to Day 85An 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.

Secondary

MeasureTime frameDescription
Change From Baseline to the End of Study (EOS) in Forced Expiratory Volume in One Second (FEV1)Baseline, EOS (up to Day 85)FEV1 was measured using Spirometry.
Change From Baseline to the EOS in Forced Vital Capacity (FVC)Baseline, EOS (up to Day 85)FVC was measured using Spirometry.
Change From Baseline to the EOS in Diffusing Capacity for Carbon Monoxide (DLCO)Baseline, EOS (up to Day 85)DLCO measures gas diffusion from the alveoli to the blood and is impaired by alveolar filling processes, interstitial lung diseases (ILDs), and emphysema. DLCO was measured in milliliters (mL)/minute (min)/millimeters of mercury (mmHG).

IPF Cohorts: Tmax of ARO-MMP7Pre-dose up to 6 hours post-dose on Days 1, 15, and 29
Urine PK of ARO-MMP7: Recovery of Unchanged Drug in Urine Over 0 to 24 Hours (Amount Excreted; Ae) in NHVs Enrolled in SAD CohortsPre-dose up to 24 hours post-dose on Day 1

Participant flow

Pre-assignment details

The study was divided into 3 groups: normal healthy volunteers (NHV) single ascending dose (SAD) cohorts, NHV multiple ascending dose (MAD) cohorts, and idiopathic pulmonary fibrosis (IPF) cohorts. A total of 105 participants were randomized and received treatment. Of the randomized participants, 82 were NHVs and 23 were participants with IPF.
