Safety and Preliminary Efficacy of hUCMSC-EVs in Interstitial Lung Disease
A Clinical Study to Explore the Safety and Preliminary Efficacy of Human Umbilical Cord Mesenchymal Stem Cell-Derived Extracellular Vesicles in the Treatment of Interstitial Lung Disease
This is an exploratory, randomized, single-blind, placebo-controlled, multiple-dose, dose-escalation clinical study. The study aims to evaluate the safety and preliminary efficacy of nebulized inhalation of Human Umbilical Cord Mesenchymal Stem Cell-Derived Extracellular Vesicles (hUCMSC-EVs) in patients with interstitial lung disease (ILD).
This study is designed to include three sequential dose cohorts-low, medium, and high-with dose escalation proceeding in an ascending order. Eligible subjects will be enrolled and randomized sequentially, with a planned enrollment of 8 subjects per cohort. Within each cohort, subjects will be randomly assigned in a 3:1 ratio to receive either hUCMSC-EVs or saline placebo.

Change from Baseline in Forced Vital Capacity (FVC)
Zeitfenster: From first dose to Week 24
|
Forced Vital Capacity (FVC) will be assessed using standardized spirometry in accordance with American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines.
Measurements will be performed at Baseline (prior to first dose) and at scheduled post-baseline visits.
Spirometry will be conducted using a calibrated spirometer.
Results will be summarized as absolute change from baseline and percent predicted normal values.

Change from Baseline in Diffusing Capacity of the Lung for Carbon Monoxide (DLCO)
Zeitfenster: From first dose to Week 24
|
Diffusing Capacity of the Lung for Carbon Monoxide (DLCO) will be assessed using the single-breath method in accordance with ATS/ERS guidelines.
Hemoglobin-corrected DLCO values will be recorded if applicable.
Measurements will be performed at Baseline and at scheduled post-baseline visits.
Results will be summarized as absolute change from baseline and percent predicted normal values.

Change from Baseline in St. George's Respiratory Questionnaire (SGRQ) Total Score
Zeitfenster: From first dose to Week 24
|
The St. George's Respiratory Questionnaire (SGRQ) is a disease-specific instrument designed to measure health-related quality of life in patients with chronic respiratory diseases.
The Total Score is calculated as a weighted sum of the domain scores and ranges from 0 to 100, with higher scores indicating worse health-related quality of life.
A change of 4 units is generally considered the minimal clinically important difference (MCID).
