A Clinical Study of REGEND001 for the Treatment of Chronic Obstructive Pulmonary Disease (COPD)
14. September 2026 aktualisiert von: 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.

|
Week 12, 24 and 52 after treatment
|
|
Change from baseline in DLCO
Zeitfenster: Week 12, 24 and 52 after treatment
