A Clinical Study of REGEND001 for the Treatment of Chronic Obstructive Pulmonary Disease (COPD)
14 de setembro de 2026 atualizado por: Regend Therapeutics
A Multicenter, Randomized, Blinded, Placebo-Controlled Confirmatory Clinical Trial of Autologous REGEND001 Cell Therapy for the Treatment of Chronic Obstructive Pulmonary Disease (COPD)
Chronic obstructive pulmonary disease (COPD) is a common, progressive, and heterogeneous respiratory disorder.
It is associated with substantial morbidity and mortality worldwide, leading to progressive decline in lung function, impaired quality of life, and a significant healthcare burden.
REGEND001, made from airway basal stem cells with ability to regenerate lung tissue, is promising to COPD treatment.
In this study, a multicenter, randomized, blinded, placebo-parallel-controlled trial is performed to verify the efficacy and safety of REGEND001 in treatment of COPD patients with emphysema.

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Change from baseline in the measured Diffusing Capacity of the Lung for Carbon Monoxide (DLCO）
Prazo: Week 52 after treatment
|
The change from baseline in measured DLCO is defined as the difference between the absolute measured DLCO value at baseline and that measured at the assessment time point after treatment.
|
Week 52 after treatment
|
Medidas de resultados secundários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Change from baseline in COPD Assessment Test (CAT) score
Prazo: Week 12, 24 and 52 after treatment
|
The change from baseline in CAT score is defined as the difference between the CAT score at baseline and the CAT score measured at the specified post-treatment assessment time point.
|
Week 12, 24 and 52 after treatment
|
|
Proportion of subjects with a ≥2-point improvement or worsening from baseline in CAT score
Prazo: Week 12, 24 and 52 after treatment
|
Minimal clinically important difference for CAT is recognized as 2 points.
|
Week 12, 24 and 52 after treatment
|
|
Change from baseline in DLCO
Prazo: Week 12, 24 and 52 after treatment
|
DLCO is assessed by absolute measured value, hemoglobin (Hb)-corrected measured/predicted ratios and corresponding area under curve (AUC).
|
Week 12, 24 and 52 after treatment
|
|
Proportion of subjects with a ≥11% relative improvement or worsening from baseline in absolute measured DLCO
Prazo: Week 12, 24 and 52 after treatment
|
