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)
Periodo de tiempo: 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)
Periodo de tiempo: 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
Periodo de tiempo: 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).
