A Clinical Study of REGEND001 for the Treatment of Chronic Obstructive Pulmonary Disease (COPD)

14 september 2026 uppdaterad av: 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.

Primära resultatmått

Resultatmått
Åtgärdsbeskrivning
Tidsram
Change from baseline in the measured Diffusing Capacity of the Lung for Carbon Monoxide (DLCO)

Åtgärdsbeskrivning
Tidsram
Change from baseline in COPD Assessment Test (CAT) score
Tidsram: 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
Tidsram: 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
Tidsram: 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
Tidsram: Week 12, 24 and 52 after treatment
Minimal clinically important difference (MCID) of DLCO is recognized as 11%.
Week 12, 24 and 52 after treatment
Change from baseline in alveolar volume (VA)
