November 3, 2026 updated by: Avalyn Pharma Inc.

A Multinational, Long-Term, Safety and Tolerability, Open-Label Extension Study of Subjects Who Have Participated in Avalyn Pharma Studies of Inhaled Antifibrotic Agents (AP-LTE-008 [SAIL])

This is an open-label extension study for participants who were previously enrolled in and completed an Avalyn Pharma Sponsored study with an inhaled antifibrotic, such as AP01. Eligible participants will have their final dose of drug at the end of study visit from the lead-in study and first AP-LTE-008 study visit on the same day.

Detailed Description

All participants will receive 100 mg inhaled pirfenidone inhalation solution (AP01) taken twice daily using the eFlow Nebulizer System.

The study will consist of a Screening/Baseline Visit, an open-label Treatment Period, and a Follow-up/End of Study (EOS) phone call. During the open-label Treatment Period, subjects will receive study drug (AP01 from their lead-in study). Subjects will complete an EOS follow-up phone call approximately 2 weeks after their last dose of study drug.

A paper dosing diary will be used to monitor adherence along with returns of any unused investigational product.

Description

Inclusion Criteria:

  • Previously participated in an Avalyn-sponsored inhaled antifibrotic clinical study for subjects with either idiopathic pulmonary fibrosis (IPF) (IPF subjects are excluded from the US and Canada) or progressive pulmonary fibrosis (PPF) and with the approval of the Study Physician.

Previous participation is defined as: Having completed the final visit of the Treatment Period on the full dose of study drug (either active or placebo).

  • Male subjects and female subjects of childbearing potential (FOCBP) agree to use highly effective contraception measures from the time of first dose of study drug (for the male subject) or the signing of the informed consent form (ICF) (for the female subject), during the study, and until 90 days after the last dose of study drug. Subjects agree not to donate eggs or sperm during the same period.

Exclusion Criteria:

  • Have not previously participated in an Avalyn-sponsored inhaled antifibrotic lead-in study or if the subject was permanently discontinued from the lead-in study for any reason. Subjects who discontinued study drug but continued to attend study visits are ineligible.
  • Subjects who experienced an exacerbation of asthma or of chronic obstructive pulmonary disease (COPD) requiring oral or systemic corticosteroids within 3 months of Day 1 (Screening/Baseline Visit).
  • Subjects who experienced an acute exacerbation of IPF (IPF subjects are excluded from the US and Canada) or of PPF within 3 months of Day 1 (Screening/Baseline Visit).
  • Participation in a concurrent clinical study or in a clinical study in which any other investigational drug product aside from the Avalyn nebulized antifibrotic medication from their lead-in study was administered within the previous 30 days, or 5 half-lives of the previously administered investigational product, whichever is shorter. Subjects may be enrolled in registries.
  • History of hypersensitivity and/or allergic reaction to pirfenidone or the excipients to be used in this study.

The incidence of adverse events will be evaluated from the time of signing of the informed consent until approximately 2 weeks after the last dose of study drug. Examples of potential adverse events include: respiratory symptoms, liver toxicity, and skin conditions. Study participants will be monitored for adverse events via the following: vital signs (blood pressure assessed using a sphygmomanometer, temperature assessed by thermometer, pulse and respiratory rate assessed by pulse oximeter), oxygen saturation, spirometry, physical exams, blood chemistry, and quality of life assessments.

Through end of study; average of 6 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To evaluate the long-term effect of Avalyn nebulized antifibrotic medications on lung function the change from baseline in forced vital capacity (FVC) will be evaluated.
Time Frame: Through end of study; average of 6 years

FVC will be evaluated via spirometry.

Through end of study; average of 6 years
To evaluate the long-term effect of Avalyn nebulized antifibrotic medications on stabilization of disease.
Time Frame: Through end of study; average of 6 years

Stabilization of disease will be based on computational analysis of quantitative high-resolution computed tomography (HRCT) to assess the extent and pattern of interstitial lung disease present on the HRCT scans (methodologies developed by Qureight).

Through end of study; average of 6 years
To evaluate the long-term impact of Avalyn nebulized antifibrotic medications on subject-reported quality of life (QoL).
Time Frame: Through end of study; average of 6 years

This outcome will evaluate the change from baseline in the 'Living with Pulmonary Fibrosis Symptoms and Impact Questionnaire' (L-PF) total score. The L-PF is a 23-point questionnaire with lower scores equating to 'less symptomatic' and higher scores equating to 'more symptomatic.'

Through end of study; average of 6 years
